Update on CO2 emissions  

SciTech Connect

Emissions of CO2 are the main contributor to anthropogenic climate change. Here we present updated information on their present and near-future estimates. We calculate that global CO2 emissions from fossil fuel burning decreased by 1.3% in 2009 owing to the global financial and economic crisis that started in 2008; this is half the decrease anticipated a year ago1. If economic growth proceeds as expected2, emissions are projected to increase by more than 3% in 2010, approaching the high emissions growth rates that were observed from 2000 to 20081, 3, 4. We estimate that recent CO2 emissions from deforestation and other land-use changes (LUCs) have declined compared with the 1990s, primarily because of reduced rates of deforestation in the tropics5 and a smaller contribution owing to forest regrowth elsewhere.

Commitment accounting of CO2 emissions  

Science Journals Connector (OSTI)

The world not only continues to build new coal-fired power plants, but built more new coal plants in the past decade than in any previous decade. Worldwide, an average of 89 gigawatts per year (GW yr–1) of new coal generating capacity was added between 2010 and 2012, 23 GW yr–1 more than in the 2000–2009 time period and 56 GW yr–1 more than in the 1990–1999 time period. Natural gas plants show a similar pattern. Assuming these plants operate for 40 years, the fossil-fuel burning plants built in 2012 will emit approximately 19 billion tons of CO2 (Gt CO2) over their lifetimes, versus 14 Gt CO2 actually emitted by all operating fossil fuel power plants in 2012. We find that total committed emissions related to the power sector are growing at a rate of about 4% per year, and reached 307 (with an estimated uncertainty of 192–439) Gt CO2 in 2012. These facts are not well known in the energy policy community, where annual emissions receive far more attention than future emissions related to new capital investments. This paper demonstrates the potential for 'commitment accounting' to inform public policy by quantifying future emissions implied by current investments.

Systems Analysis Systems Analysis DOE/NETL possesses strong systems analysis and policy-support capabilities. Systems analysis in support of the Innovations for Existing Plants Program consists of conducting various energy analyses that provide input to decisions on issues such as national plans and programs, resource use, environmental and energy security policies, technology options for research and development programs, and paths to deployment of energy technology. This work includes technology, benefits, and current situation and trends analyses related to CO2 emissions control. Systems analyses and economic modeling of potential new processes are crucial to providing sound guidance to R&D efforts. Since the majority of new CO2 capture technologies are still at a bench scale level of development, a conceptual design is first generated with emphasis on mass and energy balances. Based on available data and/or engineering estimates, these systems are optimized, and "what-if" scenarios are evaluated to identify barriers to deployment and help the process developers establish system performance targets. Reports that have been generated describing systems analyses in support of carbon capture efforts are shown in the table below.

Post-Combustion CO2 Control Post-Combustion CO2 Control Post-combustion CO2 control systems separate CO2 from the flue gas produced by conventional coal combustion in air. The flue gas is at atmospheric pressure and has a CO2 concentration of 10-15 volume percent. Read More! Capturing CO2 under these conditions is challenging because: (1) the low pressure and dilute concentration dictate a high total volume of gas to be treated; (2) trace impurities in the flue gas tend to reduce the effectiveness of the CO2 separation processes; and (3) compressing captured CO2 from atmospheric pressure to pipeline pressure (1,200 - 2,200 pounds per square inch) represents a large parasitic energy load.

Life cycle assessment of CO2 emissions from wind power plants: Methodology and case studies  

Science Journals Connector (OSTI)

Wind energy plays an increasingly important role in the world’s electricity market with rapid growth projected in the future. In order to evaluate the potential for wind energy to mitigate the effects of climate change by reducing CO2 intensity of the energy sector, this study developed a new direct and simple method for estimating CO2 emissions per kWh produced during the life cycle of four representative wind power plants (three in developed countries and one in China). The life cycle analysis focuses on the wind power plant as the basic functional object instead of a single wind turbine. Our results show that present-day wind power plants have a lifetime emission intensity of 5.0–8.2 g CO2/kWh electricity, a range significantly lower than estimates in previous studies. Our estimate suggests that wind is currently the most desirable renewable energy in terms of minimizing CO2 emissions per kWh of produced electricity. The production phase contributes the most to overall CO2 emissions, while recycling after decommission could reduce emissions by nearly half, representing an advantage of wind when compared with other energy generation technologies such as nuclear. Compared with offshore wind plants, onshore plants have lower CO2 emissions per kWh electricity and require less transmission infrastructure. Analysis of a case in China indicates that a large amount of CO2 emissions could be saved in the transport phase in large countries by using shorter alternative routes of transportation. As the world’s fastest growing market for wind power, China could potentially save 780 Mtons of CO2 emissions annually by 2030 with its revised wind development target. However, there is still ample room for even more rapid development of wind energy in China, accompanied by significant opportunities for reducing overall CO2 emissions.

Energy use, cost and CO2 emissions of electric cars  

Science Journals Connector (OSTI)

We examine efficiency, costs and greenhouse gas emissions of current and future electric cars (EV), including the impact from charging EV on electricity demand and infrastructure for generation and distribution. Uncoordinated charging would increase national peak load by 7% at 30% penetration rate of EV and household peak load by 54%, which may exceed the capacity of existing electricity distribution infrastructure. At 30% penetration of EV, off-peak charging would result in a 20% higher, more stable base load and no additional peak load at the national level and up to 7% higher peak load at the household level. Therefore, if off-peak charging is successfully introduced, electric driving need not require additional generation capacity, even in case of 100% switch to electric vehicles. GHG emissions from electric driving depend most on the fuel type (coal or natural gas) used in the generation of electricity for charging, and range between 0 g km?1 (using renewables) and 155 g km?1 (using electricity from an old coal-based plant). Based on the generation capacity projected for the Netherlands in 2015, electricity for EV charging would largely be generated using natural gas, emitting 35–77 g CO2 eq km?1. We find that total cost of ownership (TCO) of current EV are uncompetitive with regular cars and series hybrid cars by more than 800 € year?1. TCO of future wheel motor PHEV may become competitive when batteries cost 400 € kWh?1, even without tax incentives, as long as one battery pack can last for the lifespan of the vehicle. However, TCO of future battery powered cars is at least 25% higher than of series hybrid or regular cars. This cost gap remains unless cost of batteries drops to 150 € kWh?1 in the future.

The effect of natural gas supply on US renewable energy and CO2 emissions  

Science Journals Connector (OSTI)

Increased use of natural gas has been promoted as a means of decarbonizing the US power sector, because of superior generator efficiency and lower CO2 emissions per unit of electricity than coal. We model the effect of different gas supplies on the US power sector and greenhouse gas (GHG) emissions. Across a range of climate policies, we find that abundant natural gas decreases use of both coal and renewable energy technologies in the future. Without a climate policy, overall electricity use also increases as the gas supply increases. With reduced deployment of lower-carbon renewable energies and increased electricity consumption, the effect of higher gas supplies on GHG emissions is small: cumulative emissions 2013–55 in our high gas supply scenario are 2% less than in our low gas supply scenario, when there are no new climate policies and a methane leakage rate of 1.5% is assumed. Assuming leakage rates of 0 or 3% does not substantially alter this finding. In our results, only climate policies bring about a significant reduction in future CO2 emissions within the US electricity sector. Our results suggest that without strong limits on GHG emissions or policies that explicitly encourage renewable electricity, abundant natural gas may actually slow the process of decarbonization, primarily by delaying deployment of renewable energy technologies.

Post-Combustion CO2 Capture for Existing PC Boilers by Self-concentrating Amine Absorbent Post-Combustion CO2 Capture for Existing PC Boilers by Self-concentrating Amine Absorbent Project No.: DE-FE0004274 3H Company will evaluate the feasibility of its "Self-Concentrating Absorbent CO2 Capture Process." The process is based on amines in a non-aqueous solvent which, upon reaction with CO2, separate into two distinct phases: a CO2-rich liquid phase and a dilute lean phase. The proposed process offers several potential advantages. Preliminary experimental data show that the process has the potential of reducing the total regeneration energy by as much as 70 percent. The solvent has high working capacity, thus required solvent volume would be lower than that required in a currently available amine system. This results in lower pumping requirements, lower auxiliary power demands, and reduced equipment size. In addition, since the solvent is non-aqueous, corrosion issues would be reduced. During the three-year project, an engineering design supported by laboratory data and economic justification will be developed to construct and operate a slipstream demonstration facility at an E-ON power plant in the United States as a next stage of commercialization development.

Decomposition analysis of CO2 emissions from electricity generation in China  

Science Journals Connector (OSTI)

Electricity generation in China mainly depends on coal and its products, which has led to the increase in CO2 emissions. This paper intends to analyze the current status of CO2 emissions from electricity generation in China during the period 1991–2009, and apply the logarithmic mean Divisia index (LMDI) technique to find the nature of the factors influencing the changes in CO2 emissions. The main results as follows: (1) CO2 emission from electricity generation has increased from 530.96 Mt in 1991 to 2393.02 Mt in 2009, following an annual growth rate of 8.72%. Coal products is the main fuel type for thermal power generation, which accounts for more than 90% CO2 emissions from electricity generation. (2) This paper also presents CO2 emissions factor of electricity consumption, which help calculate CO2 emission from final electricity consumption. (3) In China, the economic activity effect is the most important contributor to increase CO2 emissions from electricity generation, but the electricity generation efficiency effect plays the dominant role in decreasing CO2 emissions.

Hybrid Membrane/Absorption Process for Post-Combustion CO2 Capture Hybrid Membrane/Absorption Process for Post-Combustion CO2 Capture Project No.: DE-FE0004787 Gas Technology Institute is partnering with PoroGen Corporation and Aker Process Systems in a three-year effort to develop a hybrid technology for CO2 capture from flue gases based on a combination of solvent absorption and hollow fiber membrane technologies. The technology could also apply to removal of numerous other gas pollutants such as NOx and SOx, separation of CO2 from hydrogen in refinery streams, and separation of CO2 from natural gas (natural gas sweetening). The technology increases interfacial gas/liquid area by a factor of ten over conventional packed or tray columns, thus increasing mass transfer. The selectivity is controlled by the chemical affinity of CO2 with a hindered amine. The process results in lower steam regeneration energy, and the CO2 is generated at pressure, reducing compression costs. The project includes bench-scale testing on a 25 kWe-equivalent slipstream at Midwest Generation's Joliet Power Station.

The nexus of electricity consumption, economic growth and CO2 emissions in the BRICS countries  

Science Journals Connector (OSTI)

Abstract This study reexamines the causal link between electricity consumption, economic growth and CO2 emissions in the BRICS countries (i.e., Brazil, Russia, India, China, and South Africa) for the period 1990–2010, using panel causality analysis, accounting for dependency and heterogeneity across countries. Regarding the electricity–GDP nexus, the empirical results support evidence on the feedback hypothesis for Russia and the conservation hypothesis for South Africa. However, a neutrality hypothesis holds for Brazil, India and China, indicating neither electricity consumption nor economic growth is sensitive to each other in these three countries. Regarding the GDP–CO2 emissions nexus, a feedback hypothesis for Russia, a one-way Granger causality running from GDP to CO2 emissions in South Africa and reverse relationship from CO2 emissions to GDP in Brazil is found. There is no evidence of Granger causality between GDP and CO2 emissions in India and China. Furthermore, electricity consumption is found to Granger cause CO2 emissions in India, while there is no Granger causality between electricity consumption and CO2 emissions in Brazil, Russia, China and South Africa. Therefore, the differing results for the BRICS countries imply that policies cannot be uniformly implemented as they will have different effects in each of the BRICS countries under study.

Mitigating CO2 emissions by adjusting the power generation mix in Taiwan  

Science Journals Connector (OSTI)

In this paper, we employ a multi-objective programming model to estimate the power generation mix trade-off between generation costs and CO2 emissions in Taiwan. Eight policy scenarios are simulated and compared to the reference and base cases. The empirical results show that, for the electricity sector, CO2 emissions in 2010 could be set at 120% of the 1990 level, by way of promoting cogeneration and gas-fired generation capacity. The estimated per unit mitigation cost of CO2 emission would be US$358/ton. The policy implications are discussed and limitation of this study is also presented.

Spatial Disaggregation of CO2 Emissions for the State of California  

SciTech Connect

This report allocates California's 2004 statewide carbon dioxide (CO2) emissions from fuel combustion to the 58 counties in the state. The total emissions are allocated to counties using several different methods, based on the availability of data for each sector. Data on natural gas use in all sectors are available by county. Fuel consumption by power and combined heat and power generation plants is available for individual plants. Bottom-up models were used to distribute statewide fuel sales-based CO2 emissions by county for on-road vehicles, aircraft, and watercraft. All other sources of CO2 emissions were allocated to counties based on surrogates for activity. CO2 emissions by sector were estimated for each county, as well as for the South Coast Air Basin. It is important to note that emissions from some sources, notably electricity generation, were allocated to counties based on where the emissions were generated, rather than where the electricity was actually consumed. In addition, several sources of CO2 emissions, such as electricity generated in and imported from other states and international marine bunker fuels, were not included in the analysis. California Air Resource Board (CARB) does not include CO2 emissions from interstate and international air travel, in the official California greenhouse gas (GHG) inventory, so those emissions were allocated to counties for informational purposes only. Los Angeles County is responsible for by far the largest CO2 emissions from combustion in the state: 83 Million metric tonnes (Mt), or 24percent of total CO2 emissions in California, more than twice that of the next county (Kern, with 38 Mt, or 11percent of statewide emissions). The South Coast Air Basin accounts for 122 MtCO2, or 35percent of all emissions from fuel combustion in the state. The distribution of emissions by sector varies considerably by county, with on-road motor vehicles dominating most counties, but large stationary sources and rail travel dominating in other counties.The CO2 emissions data by county and source are available upon request.

Spatial Relationships of Sector-Specific Fossil-fuel CO2 Emissions in the United States  

SciTech Connect

Quantification of the spatial distribution of sector-specific fossil fuel CO2 emissions provides strategic information to public and private decision-makers on climate change mitigation options and can provide critical constraints to carbon budget studies being performed at the national to urban scales. This study analyzes the spatial distribution and spatial drivers of total and sectoral fossil fuel CO2 emissions at the state and county levels in the United States. The spatial patterns of absolute versus per capita fossil fuel CO2 emissions differ substantially and these differences are sector-specific. Area-based sources such as those in the residential and commercial sectors are driven by a combination of population and surface temperature with per capita emissions largest in the northern latitudes and continental interior. Emission sources associated with large individual manufacturing or electricity producing facilities are heterogeneously distributed in both absolute and per capita metrics. The relationship between surface temperature and sectoral emissions suggests that the increased electricity consumption due to space cooling requirements under a warmer climate may outweigh the savings generated by lessened space heating. Spatial cluster analysis of fossil fuel CO2 emissions confirms that counties with high (low) CO2 emissions tend to be clustered close to other counties with high (low) CO2 emissions and some of the spatial clustering extends to multi-state spatial domains. This is particularly true for the residential and transportation sectors, suggesting that emissions mitigation policy might best be approached from the regional or multi-state perspective. Our findings underscore the potential for geographically focused, sector-specific emissions mitigation strategies and the importance of accurate spatial distribution of emitting sources when combined with atmospheric monitoring via aircraft, satellite and in situ measurements.

Potential Energy Savings and CO2 Emissions Reduction of China's Cement Potential Energy Savings and CO2 Emissions Reduction of China's Cement Industry Title Potential Energy Savings and CO2 Emissions Reduction of China's Cement Industry Publication Type Report Year of Publication 2012 Authors Ke, Jing, Nina Zheng, David Fridley, Lynn K. Price, and Nan Zhou Date Published 06/2012 Publisher Lawrence Berkeley National Laboratory Keywords cement industry, china energy, china energy group, emission reduction, energy analysis and environmental impacts department, energy efficiency, industrial energy efficiency, Low Emission & Efficient Industry, policy studies Abstract This study analyzes current energy and carbon dioxide (CO2) emission trends in China's cement industryas the basis for modeling different levels of cement production and rates of efficiency improvement andcarbon reduction in 2011-2030. Three cement output projections are developed based on analyses ofhistorical production and physical and macroeconomic drivers. For each of these three productionprojections, energy savings and CO2 emission reduction potentials are estimated in a best practicescenario and two continuous improvement scenarios relative to a frozen scenario. The results reveal thepotential for cumulative final energy savings of 27.1 to 37.5 exajoules and energy-related directemission reductions of 3.2 to 4.4 gigatonnes in 2011-2030 under the best practice scenarios. Thecontinuous improvement scenarios produce cumulative final energy savings of 6.0 to 18.9 exajoules andreduce CO2 emissions by 1.0 to 2.4 gigatonnes. This analysis highlights that increasing energy efficiencyis the most important policy measure for reducing the cement industry's energy and emissions intensity,given the current state of the industry and the unlikelihood of significant carbon capture and storagebefore 2030. In addition, policies to reduce total cement production offer the most direct way ofreducing total energy consumption and CO2 emissions.

The dynamic links between CO2 emissions, economic growth and coal consumption in China and India  

Science Journals Connector (OSTI)

In this study, we employ recent and robust estimation techniques of cointegration to provide more conclusive evidence on the nexus of CO2 emissions, economic growth and coal consumption in China and India. Furthermore, the causal relationships among the variables are further examined using the Granger causality test. Our empirical results suggest that the variables are cointegrated in the case of China but not India. In other words, there is a long-run relationship between CO2 emissions, economic growth and coal consumption in China. Granger causality test for China reveal a strong evidence of uni-directional causality running from economic growth to CO2 emissions. Moreover, there is a bi-directional causality between economic growth and coal consumption as well as CO2 emissions and coal consumption in the short and long run. In the case of India, only a short-run causality is detected. Causality between economic growth and CO2 emissions as well as CO2 emissions and coal consumption are bi-directional. Nonetheless, there is only a uni-directional Granger causality running from economic growth to coal consumption in India. The implications of the results are further discussed.

Yung Journal Atmospheric Chemistry and Physics Volume 13 Pagination 4359-4372 Abstract Attributing observed CO2 variations to human or natural cause is critical to deducing and tracking emissions from observations. We have used in situ CO2, CO, and planetary boundary layer height (PBLH) measurements recorded during the CalNex-LA (CARB et al., 2008) ground campaign of 15 May-15 June 2010, in Pasadena, CA, to deduce the diurnally varying anthropogenic component of observed CO2 in the megacity of Los Angeles (LA). This affordable and simple technique, validated by carbon isotope observations and WRF-STILT (Weather Research and Forecasting model - Stochastic Time-Inverted Lagrangian Transport model) predictions, is shown to robustly attribute observed CO2 variation to anthropogenic or biogenic origin over the entire diurnal cycle. During CalNex-LA, local fossil fuel combustion contributed up to ~50% of the observed CO2 enhancement overnight, and ~100% of the enhancement near midday. This suggests that sufficiently accurate total column CO2 observations recorded near midday, such as those from the GOSAT or OCO-2 satellites, can potentially be used to track anthropogenic emissions from the LA megacity.

Decarbonization and the time-delay between peak CO2 emissions and concentrations  

E-Print Network (OSTI)

Carbon-dioxide (CO2) is the main contributor to anthropogenic global warming, and the timing of its peak concentration in the atmosphere is likely to govern the timing of maximum radiative forcing. While dynamics of atmospheric CO2 is governed by multiple time-constants, we idealize this by a single time-constant to consider some of the factors describing the time-delay between peaks in CO2 emissions and concentrations. This time-delay can be understood as the time required to bring CO2 emissions down from its peak to a small value, and is governed by the rate of decarbonizaton of economic activity. This decarbonization rate affects how rapidly emissions decline after having achieved their peak, and a rapid decline in emissions is essential for limiting peak radiative forcing. Long-term mitigation goals for CO2 should therefore consider not only the timing of peak emissions, but also the rate of decarbonization. We discuss implications for mitigation of the fact that the emissions peak corresponds to small bu...

Energy intensities and CO2 emissions in Catalonia: a SAM analysis  

Science Journals Connector (OSTI)

In this paper, we estimate sectoral energy intensities and CO2 emissions for the Catalonian economy. In order to evaluate energy intensities, we use the SAM (Social Accounting Matrix) multiplier analysis applied to a SAM of the economy. CO2 emissions are estimated by means of the Leontief input-output submodel of the SAM, together with a table of coefficients of emissions per unit of monetary expenditures. This new methodology allows us to dispense with energy input-output tables for the base period. Our results are of the same order of magnitude as others obtained by physical measurement methods. We also simulate how changes in demand and energy energy efficiency parameters may affect CO2 emissions for the economy.

CO2 emission reduction from natural gas power stations using a precipitating solvent absorption process  

Science Journals Connector (OSTI)

Abstract There has been a rapid increase in the use of natural gas for power generation based on gas turbine technology which elevates the importance of carbon dioxide (CO2) capture technology to reduce CO2 emissions from gas turbine based power stations. The low content of CO2 in the gas turbine exhaust results in low rates of CO2 absorption and larger absorption equipment when compared to studies done on coal fired power stations. Furthermore the high oxygen (O2) content in the exhaust gas adversely affects the solvent stability, particularly for the traditional amine based solvents. This paper describes how exhaust gas recirculation (EGR) along with CO2CRC's low cost “UNO MK 3” precipitating potassium carbonate (K2CO3) process can overcome the challenges of CO2 capture from gas turbine power stations. To further bring down the energy requirements of the capture process, heat integration of the UNO MK 3 process with power generation process is carried out. An economic analysis of the various retrofit options is performed. The current study shows that in the case of retrofitting the UNO MK 3 process to a natural gas combined cycle (NGCC), the use of EGR can reduce the energy penalty of CO2 capture by 15%, whilst a reduction of up to 25% can be achieved with the heat integration strategies described. Significantly the study shows that converting an existing open cycle gas turbine (OCGT) to a combined cycle with steam generation along with retrofitting CO2 capture presents a different steam cycle design for the maximum power output from the combined cycle with CO2 capture. Such a conversion actually produces more power and offers an alternative low emission retrofit pathway for gas fired power. Cost analysis shows that inclusion of the UNO MK 3 CO2 capture process with EGR to an existing NGCC is expected to increase the cost of electricity (COE) by 20%. However, retrofit/repowering of an underutilised or peaking OCGT station with the inclusion of CO2 capture can reduce the COE as well as produce low emission power. This is achieved by increasing the load factor and incorporating a purpose built steam generation cycle.

The Potential for Increased Atmospheric CO2 Emissions and Accelerated Consumption of Deep Geologic CO2 Storage Resources Resulting from the Large-Scale Deployment of a CCS-Enabled Unconventional Fossil Fuels Industry in the U.S.  

SciTech Connect

Desires to enhance the energy security of the United States have spurred significant interest in the development of abundant domestic heavy hydrocarbon resources including oil shale and coal to produce unconventional liquid fuels to supplement conventional oil supplies. However, the production processes for these unconventional fossil fuels create large quantities of carbon dioxide (CO2) and this remains one of the key arguments against such development. Carbon dioxide capture and storage (CCS) technologies could reduce these emissions and preliminary analysis of regional CO2 storage capacity in locations where such facilities might be sited within the U.S. indicates that there appears to be sufficient storage capacity, primarily in deep saline formations, to accommodate the CO2 from these industries. Nevertheless, even assuming wide-scale availability of cost-effective CO2 capture and geologic storage resources, the emergence of a domestic U.S. oil shale or coal-to-liquids (CTL) industry would be responsible for significant increases in CO2 emissions to the atmosphere. The authors present modeling results of two future hypothetical climate policy scenarios that indicate that the oil shale production facilities required to produce 3MMB/d from the Eocene Green River Formation of the western U.S. using an in situ retorting process would result in net emissions to the atmosphere of between 3000-7000 MtCO2, in addition to storing potentially 900-5000 MtCO2 in regional deep geologic formations via CCS in the period up to 2050. A similarly sized, but geographically more dispersed domestic CTL industry could result in 4000-5000 MtCO2 emitted to the atmosphere in addition to potentially 21,000-22,000 MtCO2 stored in regional deep geologic formations over the same period. While this analysis shows that there is likely adequate CO2 storage capacity in the regions where these technologies are likely to deploy, the reliance by these industries on large-scale CCS could result in an accelerated rate of utilization of the nation’s CO2 storage resource, leaving less high-quality storage capacity for other carbon-producing industries including electric power generation.

Options for reducing CO2 emissions from personal travel in Europe  

Science Journals Connector (OSTI)

Personal travel is an increasingly important aspect of European society. Our demand for travel, in terms of time, money and mobility, is steadily increasing. This growth has led to a number of undesirable effects, including a substantial contribution to global warming through the emission of carbon dioxide (CO2). To address this issue, a number of solutions are available. Already the technology is established for highly economical cars, but experience shows that incentives or regulations are required in order to stimulate widespread interest in saving fuel. Similarly, alternative fuels can offer considerable reductions in greenhouse emissions, depending on the source of the energy. In the longer run, it is essential that technological measures are complemented by policies to reduce the need to travel, whilst still maintaining accessibility. This paper presents a list of policies that are being investigated as part of a strategy for reducing CO2 emissions from personal travel in Britain.

Tropical forest responses to increasing [CO2]: current knowledge and opportunities for future research  

SciTech Connect

Elevated atmospheric [CO2] (ca) will undoubtedly affect the metabolism of tropical forests worldwide; however, critical aspects of how tropical forests will respond remain largely unknown. Here we review the current state of knowledge about physiological and ecological responses, with the aim of providing a framework that can help to guide future experimental research. Modelling studies have indicated that elevated ca can potentially stimulate photosynthesis more in the tropics than at higher latitudes, because suppression of photorespiration by elevated ca increases with temperature. However, canopy leaves in tropical forests could also potentially reach a high temperature threshold under elevated ca that will moderate the rise in photosynthesis. Belowground responses, including fine root production, nutrient foraging, and soil organic matter processing, will be especially important to the integrated ecosystem response to elevated CO2. Water-use efficiency will increase as ca rises, potentially impacting upon soil moisture status and nutrient availability. Recruitment may be differentially altered for some functional groups, potentially decreasing ecosystem carbon storage. Whole-forest CO2 enrichment experiments are urgently needed to test predictions of tropical forest functioning under elevated ca. Smaller scale experiments in the understory and in gaps would also be informative, and could provide stepping stones toward stand-scale manipulations.

Energy use and CO2 emissions reduction potential in passenger car fleet using zero emission vehicles and lightweight materials  

Science Journals Connector (OSTI)

Introduction of \\{ZEVs\\} (zero emission vehicles) and lightweight materials in a conventional steel-intensive internal combustion engine vehicle fleet will affect energy consumption and automotive material requirements. We developed a bottom-up dynamic accounting model of the light-duty vehicle fleet, including vehicle production and disposal, with detailed coverage of powertrains and automotive materials. The model was used to study the potential for energy consumption and CO2 emissions reduction of \\{ZEVs\\} and lightweight materials in the Colombian passenger car fleet from 2010 to 2050. Results indicate that passenger car stock in Colombia is increased by 6.6 times between 2010 and 2050. In the base scenario energy consumption and CO2 emissions are increased by 5.5 and 4.9 times respectively. Lightweighting and battery electric vehicles offer the largest tank-to-wheel energy consumption and CO2 emissions reductions, 48 and 61% respectively, compared to 2050 baseline values. Slow stock turnover and fleet size increment prevent larger reductions. Switching to electric powertrains has larger impact than lightweighting on energy consumption and CO2 emissions. Iron and steel remain major materials in new cars. Aluminum consumption increases in all scenarios; while carbon fiber reinforced polymer consumption only increases due to fuel cell hybrid electric vehicle or lightweight vehicle use.

Combining indicators of energy consumption and CO2 emissions: a cross-country comparison  

Science Journals Connector (OSTI)

When countries are compared in terms of their carbon emission intensities, carbon emissions are normally considered as a function of either energy consumption, GDP, population or any other suitable variable. These can be termed as partial indicators as they consider emissions as a function of only one variable. Simultaneous consideration of more variables affecting carbon emissions is relatively complex. In this paper, several variables are simultaneously considered in comparing carbon emissions of countries using a new mathematical programming methodology, called the Data Envelopment Analysis. We have illustrated the use of the methodology with four variables representing CO2 emissions, energy consumption and economic activity. The illustrative analysis shows that Luxembourg, Norway, Sudan, Switzerland and Tanzania have been considered the most efficient countries, followed by India and Nigeria. Central European countries such as Poland, Romania, the Czech Republic, and South Africa are the least efficient.

Abstract Climate change and global warming as the main human societies’ threats are fundamentally associated with energy consumption and GHG emissions. The residential sector, representing 27% and 17% of global energy consumption and CO2 emissions, respectively, has a considerable role to mitigate global climate change. Ten countries, including China, the US, India, Russia, Japan, Germany, South Korea, Canada, Iran, and the UK, account for two-thirds of global CO2 emissions. Thus, these countries’ residential energy consumption and GHG emissions have direct, significant effects on the world environment. The aim of this paper is to review the status and current trends of energy consumption, CO2 emissions and energy policies in the residential sector, both globally and in those ten countries. It was found that global residential energy consumption grew by 14% from 2000 to 2011. Most of this increase has occurred in developing countries, where population, urbanization and economic growth have been the main driving factors. Among the ten studied countries, all of the developed ones have shown a promising trend of reduction in CO2 emissions, apart from the US and Japan, which showed a 4% rise. Globally, the residential energy market is dominated by traditional biomass (40% of the total) followed by electricity (21%) and natural gas (20%), but the total proportion of fossil fuels has decreased over the past decade. Energy policy plays a significant role in controlling energy consumption. Different energy policies, such as building energy codes, incentives, energy labels have been employed by countries. Those policies can be successful if they are enhanced by making them mandatory, targeting net-zero energy building, and increasing public awareness about new technologies. However, developing countries, such as China, India and Iran, still encounter with considerable growth in GHG emissions and energy consumption, which are mostly related to the absence of strong, efficient policy.

Sequestering CO 2 significantly reduces the CO 2 emissions from the power plant itself, but this is not the total picture. CO 2 capture and sequestration consumes additional energy, thus lowering the plant's fuel to electricity efficiency. To compensate for this, more fossil fuel must be

Energy consumption and related CO2 emissions in five Latin American countries: Changes from 1990 to 2006 and perspectives  

Science Journals Connector (OSTI)

This study examines the primary energy consumption and energy-related CO2 emissions in Argentina, Brazil, Colombia, Mexico and Venezuela during the period 1990–2006. It also reviews important reforms in the energy sector of these countries as well as the promotion of energy efficiency (EE) and renewable energy sources (RES). Using a decomposition analysis, results indicate that even though significant reductions in energy intensity have been achieved in Colombia, Mexico and in a lesser extent in Brazil and Argentina, the reduction of CO2 emissions in these countries has not been significant due to an increased dependence on fossil fuels in their energy mix. Although the Latin American region has an important experience in the promotion of EE programs and renewable sources, the energy agenda of the examined countries focused mostly on the energy reforms during the analyzed period. The policy review suggests that further governmental support and strong public policies towards a more sustainable energy path are required to encourage a low carbon future in the region.

Investigating the impact of nuclear energy consumption on GDP growth and CO2 emission: A panel data analysis  

Science Journals Connector (OSTI)

Abstract This study investigates the influence of nuclear energy consumption on GDP growth and CO2 emission in 30 major nuclear energy consuming countries. The panel mode was used taking the period 1990–2010. The results of the study indicated that nuclear energy consumption has a positive long run effect on GDP growth while it has no long run effect on CO2 emission. The Granger causality test results also revealed that nuclear energy consumption has a positive short run causal relationship with GDP growth while it has a negative short run causal relationship with CO2 emission. Based on the results of this study, nuclear energy consumption has an important role in increasing GDP growth in the investigated countries with no effect on CO2 emission. Consequently, unlike fossil fuels which also increase GDP growth, nuclear energy consumption causes less damage to the environment. From the results of the study, a number of recommendations were provided for the investigated countries.

Observation of CH4 and other Non-CO2 Green House Gas Emissions from California  

SciTech Connect

In 2006, California passed the landmark assembly bill AB-32 to reduce California's emissions of greenhouse gases (GHGs) that contribute to global climate change. AB-32 commits California to reduce total GHG emissions to 1990 levels by 2020, a reduction of 25 percent from current levels. To verify that GHG emission reductions are actually taking place, it will be necessary to measure emissions. We describe atmospheric inverse model estimates of GHG emissions obtained from the California Greenhouse Gas Emissions Measurement (CALGEM) project. In collaboration with NOAA, we are measuring the dominant long-lived GHGs at two tall-towers in central California. Here, we present estimates of CH{sub 4} emissions obtained by statistical comparison of measured and predicted atmospheric mixing ratios. The predicted mixing ratios are calculated using spatially resolved a priori CH{sub 4} emissions and surface footprints, that provide a proportional relationship between the surface emissions and the mixing ratio signal at tower locations. The footprints are computed using the Weather Research and Forecast (WRF) coupled to the Stochastic Time-Inverted Lagrangian Transport (STILT) model. Integral to the inverse estimates, we perform a quantitative analysis of errors in atmospheric transport and other factors to provide quantitative uncertainties in estimated emissions. Regressions of modeled and measured mixing ratios suggest that total CH{sub 4} emissions are within 25% of the inventory estimates. A Bayesian source sector analysis obtains posterior scaling factors for CH{sub 4} emissions, indicating that emissions from several of the sources (e.g., landfills, natural gas use, petroleum production, crops, and wetlands) are roughly consistent with inventory estimates, but livestock emissions are significantly higher than the inventory. A Bayesian 'region' analysis is used to identify spatial variations in CH{sub 4} emissions from 13 sub-regions within California. Although, only regions near the tower are significantly constrained by the tower measurements, CH{sub 4} emissions from the south Central Valley appear to be underestimated in a manner consistent with the under-prediction of livestock emissions. Finally, we describe a pseudo-experiment using predicted CH{sub 4} signals to explore the uncertainty reductions that might be obtained if additional measurements were made by a future network of tall-tower stations spread over California. These results show that it should be possible to provide high-accuracy estimates of surface CH{sub 4} emissions for multiple regions as a means to verify future emissions reductions.

Greenhouse gas emission reduction anticipating CO2 capture. How ready are you?  

Science Journals Connector (OSTI)

The Dutch Ministry of Spatial Planning and the Environment (VROM) engaged Jacobs Consultancy to develop a definition and measuring tool aimed at quantifying the CO2 Capture Readiness of a combustion plant. The tool developed tests the level and completeness of pre-project execution information. The testing of pre-project information is a standard practice in the refining and petrochemical industry and Jacobs Consultancy has adapted and tailored these practices to develop the Capture Readiness tool. The tool was developed in 2008 and was pilot tested on two already permitted coal fired power plant projects in 2009. The Capture Readiness tool is similar in concept to the well known Project Definition Rating Index originally introduced by the Construction Industry Institute for Major Capital Projects. The tool quantifies the readiness of a project to accommodate future CO2 capture and parallels the phased approached to Major Capital Projects used by the Project Definition Rating Index. A short introduction to the application of the PDRI methodology to test the completeness of the project development information–often also referred to as Front End Loading or FEL, is included in this paper to establish the parallel approach we have used in the development of the Capture Readiness tool. The Jacobs Consultancy Capture Readiness tool is then discussed in more detail.

Inventory of China's Energy-Related CO2 Emissions in 2008  

SciTech Connect

Although China became the world's largest emitter of energy-related CO{sub 2} emissions in 2007, China does not publish annual estimates of CO{sub 2} emissions and most published estimates of China's emissions have been done by other international organizations. Undertaken at the request of the Energy Information Administration (EIA) of the US Department of Energy, this study examines the feasibility of applying the EIA emissions inventory methodology to estimate China's emissions from published Chinese data. Besides serving as a proof of concept, this study also helps develop a consistent and transparent method for estimating China's CO{sub 2} emissions using an Excel model and identified China-specific data issues and areas for improvement. This study takes a core set of data from the energy balances published in the China Energy Statistical Yearbook 2009 and China Petrochemical Corporation Yearbook 2009 and applies the EIA's eight-step methodology to estimate China's 2008 CO{sub 2} emissions. First, China's primary and secondary fuel types and consumption by end use are determined with slight discrepancies identified between the two data sources and inconsistencies in product categorization with the EIA. Second, energy consumption data are adjusted to eliminate double counting in the four potential areas identified by EIA; consumption data from China's Special Administrative Regions are not included. Physical fuel units are then converted to energy equivalents using China's standard energy measure of coal equivalent (1 kilogram = 29.27 MJ) and IPCC carbon emissions coefficients are used to calculate each fuel's carbon content. Next, carbon sequestration is estimated following EIA conventions for other petroleum products and non-energy use of secondary fuels. Emissions from international bunker fuels are also subtracted under the 'reference' calculation of estimating apparent energy consumption by fuel type and the 'sectoral' calculation of summing emissions across end-use sectors. Adjustments for the China-specific conventions of reporting foreign bunkers and domestic bunkers fueling abroad are made following IPCC definitions of international bunkers and EIA reporting conventions, while the sequestration of carbon in carbon steel is included as an additional adjustment. Under the sectoral approach, fuel consumption of bunkers and other transformation losses as well as gasoline consumption are reallocated to conform to EIA sectoral reporting conventions. To the extent possible, this study relies on official energy data from primary sources. A limited number of secondary sources were consulted to provide insight into the nature of consumption of some products and to guide the analysis of carbon sequestered in steel. Beyond these, however, the study avoided trying to estimate figures where directly unavailable, such as natural gas flaring. As a result, the basic calculations should be repeatable for other years with the core set of data from National Bureau of Statistics and Sinopec (or a similarly authoritative source of oil product data). This study estimates China's total energy-related CO{sub 2} emissions in 2008 to be 6666 Mt CO{sub 2}, including 234.6 Mt of non-fuel CO{sub 2} emissions and 154 Mt of sequestered CO{sub 2}. Bunker fuel emissions in 2008 totaled 15.9 Mt CO{sub 2}, but this figure is underestimated because fuel use by Chinese ship and planes for international transportation and military bunkers are not included. Of emissions related to energy consumption, 82% is from coal consumption, 15% from petroleum and 3% from natural gas. From the sectoral approach, industry had the largest share of China's energy-related CO{sub 2} emissions with 72%, followed by residential at 11%, transport and telecommunications at 8%, and the other four (commerce, agriculture, construction and other public) sectors having a combined share of 9%. Thermal electricity and (purchased) heat (to a lesser degree) are major sources of fuel consumption behind sectoral emissions, responsible for 2533 Mt CO2 and 321 Mt CO{sub 2}, respec

Optical emission studies of nitrogen plasma generated by IR CO2 laser pulses  

Science Journals Connector (OSTI)

Large-scale plasma produced in nitrogen gas at room temperature and pressures ranging from 4 ? 103 to 1.2 ? 105 Pa by high-power laser-induced dielectric breakdown (LIDB) has been investigated. Time-integrated optical nitrogen gas spectra excited from a CO2 laser have been measured and analysed. The spectrum of the generated plasma is dominated by the emission of strong N+ and N and very weak N2+ atomic lines and molecular features of N+2(B2?+u–X2?+g), N+2(D2?g–A2?u), N2(C3?u–B3?g) and very weak N2(B3?g–A3?+u). The relative intensities of the 0–0 band heads in the N2(C–B) and N+2(B–X) systems are very weak as compared with the chemiluminescence spectrum of nitrogen formed in a glow discharge. An excitation temperature Texc = 21?000 ± 1300 K was calculated by means of the relative intensity of ionized nitrogen atomic lines assuming local thermodynamic equilibrium. Optical breakdown threshold intensities in N2 at 9.621 µm have been determined. The physical processes leading to the LIDB of nitrogen in the power density range 0.4 J ?2 have been analysed. From our experimental observations we can suggest that, although the first electrons must appear via multiphoton ionization or natural ionization, electron cascade is the main mechanism responsible for the LIDB in nitrogen.

CO2 emission and firm heterogeneity: a study of metals and metal-based industries in India  

Science Journals Connector (OSTI)

Industrial energy efficiency has emerged as one of the key issues in India. The increasing demand for energy that leads to growing challenge of climate change has resulted major issues. It is obvious that high-energy intensity leads to high carbon intensity of the economy. This paper is an attempt to estimate the firm level CO2 emissions for the metals and metal-based industries in Indian manufacturing. Calculation of firm level emissions is carried out following IPCC reference approach methodology of carbon dioxide emission from fuel combustion. We tried to find out the inter-firm differences of CO2 emission in the metals and metal-based industries. Data for this study is collated from the CMIE PROWESS online database from 2000-2008, IEA energy statistics and IPCC conversion factors for each of the fuel types. This study found size, age, energy intensity and technology import intensity as the major determinants of CO2 emission intensity of Indian metal and metal-based firms. In addition capital and labour intensity of the firms are also related to the firms' emission intensity.

Development of Novel Carbon Sorbents for CO2 Capture Development of Novel Carbon Sorbents for CO2 Capture Project No.: DE-NT0005578 SRI International will develop a novel, high-capacity, carbon-based carbon dioxide (CO2) sorbent with moderate thermal requirements for regeneration. In the proposed process, CO2 is absorbed in a bed of carbon sorbent pellets and desorbed in a separate reactor that regenerates the sorbent and cycles it back to the absorber. The flue gas stream is cooled in a direct contact cooler (DCC) to decrease its temperature to near ambient conditions. The cooled flue gas from the DCC passes through the sorbent contained in a moving bed reactor, where CO2 is removed by adsorption. The CO2-laden sorbent is transported to a second moving bed reactor, where it is indirectly heated by steam coils to desorb the CO2. Project objectives are to validate the performance of the carbon-based sorbent concept on a bench-scale system, to perform parametric experiments to determine optimum operating conditions, and to evaluate the technical and economic viability of the technology.

Solid Sorbents as a Retrofit Technology for CO2 Capture Solid Sorbents as a Retrofit Technology for CO2 Capture Project No.: DE-FE0004343 ADA-ES Inc. is refining the conceptual design of a commercial solid sorbent-based, post-combustion CO2 capture technology through slipstream pilot testing and process modeling. A pilot unit (~1 MW) will be designed and constructed to demonstrate solid sorbent-based CO2 capture on actual flue gas. The pilot tests and process modeling will provide the information necessary to complete a techno-economic analysis of the technology. The design will be based on a 1 kW-scale transport reactor system built and demonstrated under an existing DOE/NETL CO2 capture project (Figure). There are several advantages solids offer over aqueous MEA. For example, solids have a working capacity over two times that of MEA, by weight, leading to lower regeneration energy attributable to less material to heat. The increased capacity, in conjunction with the lower heat capacity, results in a theoretical regeneration energy approximately half that of MEA, per kg of CO2. This indicates that solids can dramatically reduce the energy requirements for CO2 capture compared to aqueous systems. In addition, circulating less material in a solid-based system compared to aqueous MEA will likely lead to lower pressure drop, depending on the system configuration. Also, solids have the potential to be less corrosive than the solution used in aqueous MEA systems.

Cost of energy saving and CO2 emissions reduction in China’s iron and steel sector  

Science Journals Connector (OSTI)

Abstract This paper estimated the cost curve of energy saving and CO2 emissions reduction in China’s iron and steel sector. Forty-one energy saving technologies which are widely used or popularized are selected, their investments, operation costs, energy savings and CO2 abatement are collected and the data in 2010 are taken as a baseline. Then energy conservation supply curve and CO2 conservation supply curve under two different discount rates are calculated in the paper. These 41 technologies result in a saving contribution of 4.63 GJ/t and a CO2 abatement contribution of 443.21 kg/t. Cost-effectiveness of technologies was analyzed based on the fuel price and an estimated CO2 price. When comparing the result with the promoted technologies during the 12th five-year-plan, we found that some promoted technologies are not cost-effective in current situation. Three scenarios are set through changing the diffusion rate of technologies and the share of BOF and EAF, based on this energy saving potentials of technologies in 2020 and 2030 are forecasted. At the same time, we compared the change of the CSC depending on the year and the energy saving potentials in three scenarios of 2020 and 2030, respectively.

Current methods of CO2 post-combustion recovery from coal-fired power plants focus on such techniques as absorption in aqueous ethanolamine scrubbers - and this is now a mature technology unlikely to achieve a quantum change in either capacity or cost. The objective of this project is to develop a novel class of solvents for post-combustion recovery of CO2 from fossil fuel-fired power plants which will achieve a substantial increase in CO2 carrying capacity with a concomitant plummet in cost. The project team is a combination of chemical engineers and chemists with extensive experience in working with industrial partners to formulate novel solvents and to develop processes that are both environmentally benign and economically viable. Further, the team has already developed solvents called "reversible ionic liquids," essentially "smart" molecules which change properties abruptly in response to some stimulus, and these have quickly found a plethora of applications.

Quantification of fossil fuel CO2 emissions at the building/street scale for a large US city  

SciTech Connect

In order to advance the scientific understanding of carbon exchange with the land surface, build an effective carbon monitoring system and contribute to quantitatively-based U.S. climate change policy interests, fine spatial and temporal quantification of fossil fuel CO2 emissions, the primary greenhouse gas, is essential. Called the ‘Hestia Project’, this research effort is the first to use bottom-up methods to quantify all fossil fuel CO2 emissions down to the scale of individual buildings, road segments, and industrial/electricity production facilities on an hourly basis for an entire urban landscape. a large city (Indianapolis, Indiana USA). Here, we describe the methods used to quantify the on-site fossil fuel CO2 emissions across the city of Indianapolis, Indiana. This effort combines a series of datasets and simulation tools such as a building energy simulation model, traffic data, power production reporting and local air pollution reporting. The system is general enough to be applied to any large U.S. city and holds tremendous potential as a key component of a carbon monitoring system in addition to enabling efficient greenhouse gas mitigation and planning. We compare our estimate of fossil fuel emissions from natural gas to consumption data provided by the local gas utility. At the zip code level, we achieve a bias adjusted pearson r correlation value of 0.92 (p<0.001).

Energy conservation and CO2 emission reduction in China's 11th Five-Year Plan: A performance evaluation  

Science Journals Connector (OSTI)

Abstract In the 11th Five-Year Plan (FYP) (2005–2010), the Chinese Government initiated a series of energy-saving and emission reduction policies in many key fields in response to environmental pollution and climate change. This paper quantitatively evaluates the performance of energy conservation and CO2 emission reduction in this period, the impact of these policies and potentials, by integrating the contributions of energy conversion efficiency and energy utilization efficiency improvement, industrial restructuring, fuel mix shift and renewable energy development in a unified framework, as a first attempt to introduce energy conversion efficiency improvement into a decomposition approach. Comprehensive and specific policies are summarized as a policy list to be investigated. The results show that energy intensity and conversion efficiency effects were mainly responsible for driving down energy consumption, by 637.4 Mtce and 85.4 Mtce respectively, and they reduced CO2 emissions by 1345.3 Mt and 243.8 Mt respectively due to a significant improvement in the 11th FYP period. Most of the contributions made by the conversion efficiency effect (94%) come from thermal power generation, and the emission coefficient effect reduced CO2 emissions by 17.4 Mt through developing renewable energy. Economic growth is still the biggest driver of energy consumption and increasing emissions, while industrial restructuring and fuel mix shift effects contributed relatively little. Developing renewable energy and promoting economic restructuring to limit the increase of energy-intensive sectors are still the main challenges and the next policy focus to achieve the targets for energy saving and carbon emission reduction in the 12th Five-Year Plan.

Dynamic control of a stand-alone syngas production system with near-zero CO2 emissions  

Science Journals Connector (OSTI)

Abstract A series combination of steam methane reforming (SMR) and dry reforming of methane (DRM) is developed as a stand-alone syngas production (SASP) system in which the heat recovery mechanism can fully replace the hot/cold utilities. The optimum operating conditions can be found by using the optimization algorithm to maximize the syngas yield subject to near-zero CO2 emission constraints. Since the syngas yield and CO2 emissions are strongly affected by process interactions and unknown perturbations, the process control method is utilized to stabilize the SASP system. Through the Hammerstein model identification, nonlinear inversion and model-based control methods, it is verified that the multi-loop nonlinear control strategy can ensure satisfactory control performance.

PASSIVE WIRELESS SURFACE ACOUSTIC WAVE SENSORS FOR MONITORING SEQUESTRATION SITES CO2 EMISSION  

SciTech Connect

University of Pittsburgh’s Transducer lab has teamed with the U.S. Department of Energy’s National Energy Technology Laboratory (DOE NETL) to conduct a comprehensive study to develop/evaluate low-cost, efficient CO2 measuring technologies for geological sequestration sites leakage monitoring. A passive wireless CO2 sensing system based on surface acoustic wave technology and carbon nanotube nanocomposite was developed. Surface acoustic wave device was studied to determine the optimum parameters. Delay line structure was adopted as basic sensor structure. CNT polymer nanocomposite was fabricated and tested under different temperature and strain condition for natural environment impact evaluation. Nanocomposite resistance increased for 5 times under pure strain, while the temperature dependence of resistance for CNT solely was -1375ppm/?. The overall effect of temperature on nanocomposite resistance was -1000ppm/?. The gas response of the nanocomposite was about 10% resistance increase under pure CO2. The sensor frequency change was around 300ppm for pure CO2. With paralyne packaging, the sensor frequency change from relative humidity of 0% to 100% at room temperature decreased from over 1000ppm to less than 100ppm. The lowest detection limit of the sensor is 1% gas concentration, with 36ppm frequency change. Wireless module was tested and showed over one foot transmission distance at preferred parallel orientation.

Potential energy savings and reduction of CO2 emissions through higher efficiency standards for polyphase electric motors in Japan  

Science Journals Connector (OSTI)

Japan has shut down more than 70% of its nuclear power plants since the March 2011 Tohoku earthquake and the ensuing accident at the Fukushima Daiichi nuclear power plant. The country has been challenged with power shortages in the short-term and faces complex energy security decisions in the long-term. Japan has a long history of implementing energy conservation policies, such as the Top Runner Program, which covers 23 products including appliances and industrial equipment. However, Japan's efficiency policy for polyphase electric motors is considered below international standards. Polyphase electric motors accounted for about 55% of the nation's total power consumption in 2008. The aim of this study is to estimate potential energy savings and reduction in CO2 emissions (2014–2043) by examining scenarios involving adopting two different polyphase motor efficiency standards and comparing them to a base case and concludes by suggesting pathways for further policy development using the results obtained. The study finds that if level IE2 of the international efficiency standard IEC 60034-30 were implemented, it would save 8.3 TWh (or 0.03 quads) per year, which is equivalent to about 0.8% of Japan's total electric power consumption in 2010. If level IE3 of the IEC 60034-30 were implemented instead, it would save about 13.3 TWh (or 0.05 quads) per year. The corresponding cumulative energy savings and reduction in CO2 emissions for the IE2 scenario would be 249 TWh (or 0.85 quads) and 93 Mt. The corresponding cumulative energy savings and reduction in CO2 emissions for the IE3 scenario would be 398 TWh (or 1.36 quads) and 149 Mt.

An input-output analysis of regional CO2 emissions from the service sector: an application to Liaoning Province of China  

Science Journals Connector (OSTI)

Based on the input-output tables of Liaoning Province of China for 2007, this paper calculates direct and indirect CO2 emissions from the service sector. Total CO2 emissions of the service sector are decomposed into several effects, of which the spill-over and feedback effects are further decomposed into two parts: Energy Spill-over Effect (ESE) and Remnant Spill-over Effect (RSE); energy feedback effect and remnant feedback effect. The research shows indirect CO2 emissions derived from final demand of the service sector are far more than direct CO2 emissions, the main cause of which is the spill-over effect due to the strong pull effect of the service sector on other sectors. A further decomposition into the ESE reveals that the electricity and heating sector accounts for the largest percentage, with the coal-mining and washing sector second.

Geologic carbon sequestration as a global strategy to mitigate CO2 emissions: Sustainability and environmental risk  

SciTech Connect

Fossil fuels are abundant, inexpensive to produce, and are easily converted to usable energy by combustion as demonstrated by mankind's dependence on fossil fuels for over 80% of its primary energy supply (13). This reliance on fossil fuels comes with the cost of carbon dioxide (CO{sub 2}) emissions that exceed the rate at which CO{sub 2} can be absorbed by terrestrial and oceanic systems worldwide resulting in increases in atmospheric CO{sub 2} concentration as recorded by direct measurements over more than five decades (14). Carbon dioxide is the main greenhouse gas linked to global warming and associated climate change, the impacts of which are currently being observed around the world, and projections of which include alarming consequences such as water and food shortages, sea level rise, and social disruptions associated with resource scarcity (15). The current situation of a world that derives the bulk of its energy from fossil fuel in a manner that directly causes climate change equates to an energy-climate crisis. Although governments around the world have only recently begun to consider policies to avoid the direst projections of climate change and its impacts, sustainable approaches to addressing the crisis are available. The common thread of feasible strategies to the energy climate crisis is the simultaneous use of multiple approaches based on available technologies (e.g., 16). Efficiency improvements (e.g., in building energy use), increased use of natural gas relative to coal, and increased development of renewables such as solar, wind, and geothermal, along with nuclear energy, are all available options that will reduce net CO{sub 2} emissions. While improvements in efficiency can be made rapidly and will pay for themselves, the slower pace of change and greater monetary costs associated with increased use of renewables and nuclear energy suggests an additional approach is needed to help bridge the time period between the present and a future when low-carbon energy is considered cheap enough to replace fossil fuels. Carbon dioxide capture and storage (CCS) is one such bridging technology (1). CCS has been the focus of an increasing amount of research over the last 15-20 years and is the subject of a comprehensive IPCC report that thoroughly covers the subject (1). CCS is currently being carried out in several countries around the world in conjunction with natural gas extraction (e.g., 2, 3) and enhanced oil recovery (17). Despite this progress, widespread deployment of CCS remains the subject of research and future plans rather than present action on the scale needed to mitigate emissions from the perspective of climate change. The reasons for delay in deploying CCS more widely are concerns about cost (18), regulatory and legal uncertainty (19), and potential environmental impacts (21). This chapter discusses the long-term (decadal) sustainability and environmental hazards associated with the geologic CO{sub 2} storage (GCS) component of large-scale CCS (e.g., 20). Discussion here barely touches on capture and transport of CO{sub 2} which will occur above ground and which are similar to existing engineering, chemical processing, and pipeline transport activities and are therefore easier to evaluate with respect to risk assessment and feasibility. The focus of this chapter is on the more uncertain part of CCS, namely geologic storage. The primary concern for sustainability of GCS is whether there is sufficient capacity in sedimentary basins worldwide to contain the large of amounts of CO{sub 2} needed to address climate change. But there is also a link between sustainability and environmental impacts. Specifically, if GCS is found to cause unacceptable impacts that are considered worse than its climate-change mitigation benefits, the approach will not be widely adopted. Hence, GCS has elements of sustainability insofar as capacity of the subsurface for CO{sub 2} is concerned, and also in terms of whether the associated environmental risks are acceptable or not to the public.

Rapid growth in CO2 emissions after the 2008-2009 global financial crisis  

SciTech Connect

Global carbon dioxide emissions from fossil-fuel combustion and cement production grew 5.9% in 2010, surpassed 9 Pg of carbon (Pg C) for the first time, and more than offset the 1.4% decrease in 2009. The impact of the 2008 2009 global financial crisis (GFC) on emissions has been short-lived owing to strong emissions growth in emerging economies, a return to emissions growth in developed economies, and an increase in the fossil-fuel intensity of the world economy.

Will export rebate policy be effective for CO2 emissions reduction in China? A CEEPA-based analysis  

Science Journals Connector (OSTI)

Abstract China has adopted cancellation of export tax rebate policies on many occasions to push ahead energy conservation and emission reduction since 2007. By applying a CEEPA (China Energy & Environmental Policy Analysis system) model, this paper simulates the impacts of the cancellation of export rebates on CO2 emissions and socio-economic consequences in different scenarios so as to figure out whether it works. This paper covers three export rebate scenarios and makes comparisons between the impacts of export rebates on emission reduction effects and that of carbon tax policies. The conclusions are: 1) the current policy which cancels export rebates for key sectors can cut emissions at huge economic cost, yet it is unsustainable; 2) the policy which cancels export rebates for key sectors and meanwhile subsidizes sectoral outputs yields double dividends in the short term, thus can facilitate emission reduction yet the boost is limited; 3) the policy which cancels export rebates and boosts domestic demand helps improving residents' welfare in the short term while it may inflict pronounced social and economic impacts in the long run. So policy of this kind should be adopted with great caution; 4) export rebates generate far more economic costs than carbon tax policies in the long term, and don't contribute to optimizing the energy mix as well as the latter. In summary, canceling export rebates should not be regarded as a priority to encourage emission reduction.

Energy taxes and subsidies: their implications for CO2 emissions and abatement costs  

Science Journals Connector (OSTI)

Energy markets are often distorted, with the result that price does not equal the marginal social cost of production. Subsidies encourage consumption of energy and impose welfare losses independent of those arising from global warming. Fossil fuels, especially oil, are already taxed in many countries. The superimposition of a carbon tax on existing taxes could greatly increase the welfare loss from taxation if such taxes do not reflect externalities or user costs. Moreover, existing taxes affect relative fuel prices and may raise emission levels. The removal of subsidies and the restructuring of taxes so that fuel prices are brought into line with marginal social costs could result in emission abatement and lower abatement costs.

Control of CO2 emission through enhancing energy efficiency of auxiliary power equipment in thermal power plant  

Science Journals Connector (OSTI)

Abstract This paper describes the results of energy efficiency enhancement in 23 numbers of 210 MW coal fired power plants spread over India. Energy efficiency improvement of major auxiliary equipment with different plant load factors are summarized here with improved performance. The effect of plant load factor on all major auxiliary equipment and improvement in performance of auxiliary equipment are discussed in this paper. Operation of the plant at improved plant load factor reduced the specific auxiliary power from 11.23% at 70% PLF to 8.74% at 100% PLF that reduced the net auxiliary power by 9.1 MU/year that is an equivalent reduction of CO2 emission by 9500 t/year. Optimizing the excess air, controlling the furnace ingress, enhanced energy efficiency of individual equipment by proper maintenance, etc., improves the plant capacity and reduces the overall auxiliary power by about 1.5–2.1% of gross energy generation i.e., equivalent CO2 reduction of 23,000–32,400 t/year and release an additional power of about 3.5 MW (for a typical one 210 MW power plant) into grid.

High resolution fossil fuel combustion CO2 emission fluxes for the United States  

SciTech Connect

Quantification of fossil fuel CO{sub 2} emissions at fine space and time resolution is emerging as a critical need in carbon cycle and climate change research. As atmospheric CO{sub 2} measurements expand with the advent of a dedicated remote sensing platform and denser in situ measurements, the ability to close the carbon budget at spatial scales of {approx}100 km{sup 2} and daily time scales requires fossil fuel CO{sub 2} inventories at commensurate resolution. Additionally, the growing interest in U.S. climate change policy measures are best served by emissions that are tied to the driving processes in space and time. Here we introduce a high resolution data product (the 'Vulcan' inventory: www.purdue.edu/eas/carbon/vulcan/) that has quantified fossil fuel CO{sub 2} emissions for the contiguous U.S. at spatial scales less than 100 km{sup 2} and temporal scales as small as hours. This data product, completed for the year 2002, includes detail on combustion technology and 48 fuel types through all sectors of the U.S. economy. The Vulcan inventory is built from the decades of local/regional air pollution monitoring and complements these data with census, traffic, and digital road data sets. The Vulcan inventory shows excellent agreement with national-level Department of Energy inventories, despite the different approach taken by the DOE to quantify U.S. fossil fuel CO{sub 2} emissions. Comparison to the global 1{sup o} x 1{sup o} fossil fuel CO{sub 2} inventory, used widely by the carbon cycle and climate change community prior to the construction of the Vulcan inventory, highlights the space/time biases inherent in the population-based approach.

The effect of anthropogenic emissions corrections on the seasonal cycle of atmospheric CO2  

SciTech Connect

A previous study (Erickson et al. 2008) approximated the monthly global emission estimates of anthropogenic CO{sub 2} by applying a 2-harmonic Fourier expansion with coefficients as a function of latitude to annual CO{sub 2} flux estimates derived from United States data (Blasing et al. 2005) that were extrapolated globally. These monthly anthropogenic CO{sub 2} flux estimates were used to model atmospheric concentrations using the NASA GEOS-4 data assimilation system. Local variability in the amplitude of the simulated CO{sub 2} seasonal cycle were found to be on the order of 2-6 ppmv. Here we used the same Fourier expansion to seasonally adjust the global annual fossil fuel CO{sub 2} emissions from the SRES A2 scenario. For a total of four simulations, both the annual and seasonalized fluxes were advected in two configurations of the NCAR Community Atmosphere Model (CAM) used in the Carbon-Land Model Intercomparison Project (C-LAMP). One configuration used the NCAR Community Land Model (CLM) coupled with the CASA (carbon only) biogeochemistry model and the other used CLM coupled with the CN (coupled carbon and nitrogen cycles) biogeochemistry model. All four simulations were forced with observed sea surface temperatures and sea ice concentrations from the Hadley Centre and a prescribed transient atmospheric CO{sub 2} concentration for the radiation and land forcing over the 20th century. The model results exhibit differences in the seasonal cycle of CO{sub 2} between the seasonally corrected and uncorrected simulations. Moreover, because of differing energy and water feedbacks between the atmosphere model and the two land biogeochemistry models, features of the CO{sub 2} seasonal cycle were different between these two model configurations. This study reinforces previous findings that suggest that regional near-surface atmospheric CO{sub 2} concentrations depend strongly on the natural sources and sinks of CO{sub 2}, but also on the strength of local anthropogenic CO{sub 2} emissions and geographic position. This work further attests to the need for remotely sensed CO{sub 2} observations from space.

This paper shows the comparison results of operations of 4 space heating systems: the low-temperature radiant panel system without any additional thermal insulation of external walls (PH-WOI), the low-temperature radiant panel system with additional thermal insulation of external walls (PH-WI), the radiator system without any additional thermal insulation of external walls (the classical heating system) (RH-WOI), and the radiator system with additional thermal insulation of external walls (RH-WI). The operation of each system is simulated by software EnergyPlus. The investigation shows that the PH-WI gives the best results. The RH-WOI has the largest energy consumption, and the largest pollutant emission. However, the PH-WI requires the highest investment.

Household electricity consumption and CO2 emissions in the Netherlands: A model-based analysis  

Science Journals Connector (OSTI)

Abstract Twenty percent of the total energy consumption in the Netherlands comes from household electricity consumption. This comes from household electric appliances whose number has grown in recent years. The paper explores the effect of smart meter introduction, appliance efficiency and consumer behaviour on reducing electricity consumption in the Netherlands. It does so by combining two perspectives: a sociotechnical approach and a bottom up simulation approach. The range of scenarios explored through simulation in the paper provides an understanding of the interplay between efficiency, smart meter diffusion and consumer behaviour. The results show their effect on electricity consumption and suggest that further effort is required to control and reduce it. Insights from the paper suggest that future studies should disaggregate with respect to a number of factors.

Land and Water Use, CO2 Emissions, and Worker Radiological Exposure Factors for the Nuclear Fuel Cycle  

SciTech Connect

The Department of Energy Office of Nuclear Energy’s Fuel Cycle Technologies program is preparing to evaluate several proposed nuclear fuel cycle options to help guide and prioritize Fuel Cycle Technology research and development. Metrics are being developed to assess performance against nine evaluation criteria that will be used to assess relevant impacts resulting from all phases of the fuel cycle. This report focuses on four specific environmental metrics. • land use • water use • CO2 emissions • radiological Dose to workers Impacts associated with the processes in the front-end of the nuclear fuel cycle, mining through enrichment and deconversion of DUF6 are summarized from FCRD-FCO-2012-000124, Revision 1. Impact estimates are developed within this report for the remaining phases of the nuclear fuel cycle. These phases include fuel fabrication, reactor construction and operations, fuel reprocessing, and storage, transport, and disposal of associated used fuel and radioactive wastes. Impact estimates for each of the phases of the nuclear fuel cycle are given as impact factors normalized per unit process throughput or output. These impact factors can then be re-scaled against the appropriate mass flows to provide estimates for a wide range of potential fuel cycles. A companion report, FCRD-FCO-2013-000213, applies the impact factors to estimate and provide a comparative evaluation of 40 fuel cycles under consideration relative to these four environmental metrics.

Strategic electricity sector assessment methodology under sustainability conditions: a Swiss case study on the costs of CO2 emissions reductions  

Science Journals Connector (OSTI)

Growing concerns about social and environmental sustainability have led to increased interest in planning for the electricity utility sector because of its large resource requirements and production of emissions. A number of conflicting trends combine to make the electricity sector a major concern, even though a clear definition of how to measure progress toward sustainability is lacking. These trends include imminent competition in the electricity industry, global climate change, expected long-term growth in population and pressure to balance living standards (including per capital energy consumption). In order to approach this global problem on a regional level, a project has been established to develop planning methods for electrical power systems related to sustainability called SESAMS (Strategic Electricity Sector Assessment Methodology under Sustainability Conditions), under the Alliance for Global Sustainability formed by the Massachusetts Institute of Technology (MIT), the Swiss Federal Institutes of Technology (ETHZ and EPFL), and the University of Tokyo (UT). SESAMS 97 has brought together multi-attribute, multi-scenario electricity system planning, life-cycle assessment, and multi-criteria decision analysis to create an integrated methodology that has been demonstrated using a case study based on the Swiss electricity system. This case study has simulated system dispatch of the Swiss electricity system for 1296 scenarios over a study period from 1996 to 2025. The results for these scenarios include a wide range of direct and indirect sustainability measures, with conclusions that have focused primarily on cost and CO2 emissions. The pairwise scenario trade-off analysis facilitates searching the strategy option space by identifying the best and most robust options. Decision-makers benefit by being able to focus trade-off discussions on the dominant set of best choices for each trade-off pair, rather than covering the entire decision space.

Joining semi-closed gas turbine cycle and tri-reforming: SCGT-TRIREF as a proposal for low CO2 emissions powerplants  

Science Journals Connector (OSTI)

Methane conversion to a rich H2 fuel by reforming reactions is a largely applied industrial process. Recently, it has been considered for applications combined to gas turbine powerplants, as a mean for (I) chemical recuperation (i.e. chemical looping CRGT) and (II) decarbonising the primary fuel and make the related power cycle a low CO2 releaser. The possibility of enhancing methane conversion by the addition of CO2 to the steam reactant flow (i.e. tri-reforming) has been assessed and showed interesting results. When dealing with gas turbines, the possibility of applying tri-reforming is related to the availability of some CO2 into the fluegas going to the reformer. This happens in semi-closed gas turbine cycles (SCGT), where the fluegas has a typical 14–15% CO2 mass content. The possibility of joining CRGT and SCGT technologies to improve methane reforming and propose an innovative, low CO2 emissions gas turbine cycle was assessed here. One of the key issues of this joining is also the possibility of greatly reduce the external water consumption due to the reforming, as the SCGT is a water producer cycle. The SCGT-TRIREF cycle is an SCGT cycle where fuel tri-reforming is applied. The steam due to the reformer is generated by the vaporization of the condensed water coming out from the fluegas condensing heat exchanger, upstream the main compressor, where the exhausts are cooled down and partially recirculated. The heat due to the steam generation is recuperated from the turbine exhausts cooling. The reforming process is partially sustained by the heat recovered from the turbine exhausts (which generates superheated steam) and partially by the auto thermal reactions of methane with fresh air, coming from the compressor (i.e. partial combustion). The effect of CO2 on methane reforming (tri-reforming effect) increases with decreasing steam/methane ratio: at very low values, around 30% of methane is converted by reactions with CO2. At high values of steam/methane ratio, the steam reforming reactions are dominant and only a marginal fraction of methane is interested to tri-reforming. Under optimised conditions, which can be reached at relatively high pressure ratios (25–30), the power cycle showed a potential efficiency around 46% and specific work at 550 kJ/kg level. When the amine CO2 capture is applied, the specific CO2 emissions range between 45 and 55 g CO 2 / kW h .

Publisher Summary This chapter deals with an assessment of exiting potential, present status, and future trends of the development of various renewable energy technologies in India. The chapter also tries to correlate the overall development of the renewable energy sources in the context of carbon dioxide emission mitigation efforts. Some of the technologies, like solar water heaters, solar cookers, domestic PV lighting systems, and biogas plants for cooking and lighting have achieved a certain level of maturity to boost their scope of application in domestic sector. It reviews all of these developments. India has an extensive potential of renewable energy sources that can be developed as a significant source of energy at the local and regional level. Significant cost reduction as well as mitigation of other constraints will be needed for the renewable energy technologies to achieve their potential in supplying energy, and reduction in carbon dioxide emission in India.

Using annual numbers provides a reasonable estimation of emissions, but it provides no indication of the temporal nature of the emissions. Therefore, there is no way of understanding the impact on emissions from load shifting and peak shaving technologies such as thermal energy storage, on-site renewable energy, and demand control.

Reducing the CO2 emissions and the energy dependence of a large city area with zero-emission vehicles and nuclear energy  

Science Journals Connector (OSTI)

Abstract This paper aims to study the feasibility of implementing a strategic plan for a gradual introduction of zero-emission vehicles in the city of Madrid during 2014–2024. The study estimate the amount of emissions saved if the electrical energy needed for the vehicles is generated with nuclear power plants. The use of zero-emission vehicles could play an important role in reducing our dependence on oil and, therefore, changing the economy structure of the country. Therefore, as a representing city, Madrid's nowadays situation is studied. The city's vehicle fleet is first considered and classified. An average both daily and annually fuel consumption is made, in order to know the city's gasoline investment. Moreover, the health effects of air pollution, which is largely due to the city's vehicles, are statistically considered in order to analyze the economic impact of treating these effects. Furthermore, noise pollution and it's both direct and indirect consequences are studied. After having analyzed Madrid's situation, a comparison between some international cities and the Spanish capital is made, regarding their vehicle fleet and their environmental and economical consequences. European environmental policy and future criteria are exposed. Regarding the technical feasibility, two types of zero-emission technologies are considered, the battery-electric car and de hydrogen fuel cell vehicle (FCV). After having described the benefits and disadvantages of the use of zero-emission vehicles, a macroeconomic analysis is done in order to study the economic feasibility of the project. To do this, not only several economic variables, such as gross domestic product in the area, but also survey data, such as the average daily driving time are considered. Finally, a strategic plan for a gradual implementation of zero-emission vehicles in the city of Madrid is proposed, taking into account the quantity of emissions saved if the electrical energy needed is generated with nuclear power plants. In this plan, some policy actions are proposed for a gradual implementation. Policy actions such as special fees for those driving internal combustion engine vehicles, free parking for zero-emission vehicles or even a subsidized car replacement plan.

FutureGen: Pathway to Near-Zero Emissions and Sustainable Energy  

SciTech Connect

This presentation will highlight the U.S. Department of Energy’s (DOE) FutureGen project ? a $1 billion government-industry partnership to design, build, and operate a near-zero emissions coal-fueled power plant. The lead organization for the FutureGen initiative is the National Energy Technology Laboratory (NETL), a multi-purpose laboratory operated by the U.S. DOE’s Office of Fossil Energy. NETL has a mission to conduct R&D from fundamental science to technology demonstration for resolving the environmental, supply, and reliability constraints of producing and using fossil energy resources. The commercial-scale FutureGen R&D facility is a pathway toward future fossil-energy power plants that will produce hydrogen and electricity while nearly eliminating emissions, including carbon dioxide. The 275-megawatt FutureGen plant will initiate operations around 2012 and employ advanced coal gasification technology integrated with combined cycle electricity generation, hydrogen production, and carbon capture and sequestration. Low carbon emissions would be achieved by integrating CO2 capture and sequestration operations with the power plant.

Real-world fuel consumption and CO2 (carbon dioxide) emissions by driving conditions for light-duty passenger vehicles in China  

Science Journals Connector (OSTI)

Abstract The increasing discrepancy between on-road and type-approval fuel consumption for \\{LDPVs\\} (light-duty passenger vehicles) has attracted tremendous attention. We measured on-road emissions for 60 \\{LDPVs\\} in three China's cities and calculated their fuel consumption and CO2 (carbon dioxide) emissions. We further evaluated the impacts of variations in area-averaged speed on relative fuel consumption of gasoline \\{LDPVs\\} for the UAB (urban area of Beijing). On-road fuel consumption under the average driving pattern is 10 ± 2% higher than that normalized to the NEDC (new European driving cycle) cycle for all tested vehicles, and the on-road NEDC-normalized fuel consumption is higher by 30 ± 12% compared to type-approval values for gasoline vehicles. We observed very strong correlations between relative fuel consumption and average speed. Traffic control applied to \\{LDPVs\\} driving within the UAB during weekdays can substantially reduce total fleet fuel consumption by 23 ± 5% during restriction hours by limiting vehicle use and improving driving conditions. Our results confirmed that a new cycle for the type approval test for \\{LDPVs\\} with more real-world driving features is of great necessity. Furthermore, enhanced traffic control measures could play an important role in mitigating real-world fuel consumption and CO2 emissions for \\{LDPVs\\} in China.

A verification study on saving energy cost and reducing CO2 emission with large-scale geothermal heat pump systems in Korea  

Science Journals Connector (OSTI)

This paper presents economic and environmental effects by using monitoring data collected over a 2-yr period in geothermal heating and cooling facilities in Jungwon University Korea. The facility has heating capacity of 7045?kW and cooling capacity of 5947?kW. Such monitoring data are rarely reported in the literature; thus the evaluation based on long-term operational data will contribute greatly to the objective assessment of the geothermal heat pump system (GHPS) as a renewable energy resource. The effects of relative energy cost saving and reductions in CO2 emission were predicted for comparison with conventional heating and cooling systems. The GHPS was estimated to reduce energy costs by 76.4%–85.3% and yield a reduction of CO2 emission of 398–595 tons annually. We also conducted an economic analysis using the benefit/cost ratio (BCR) method according to scenarios in which the lifespan and discount rate for the GHPS were varied. Since the BCR for the GHPS was in the range of 1.99–3.58 (case 1) and 1.67–3.01 (case 2) GHPS is considered to be more economic than other types of heating and cooling systems. These results provide evidentiary data to help overcome skepticism over the applicability of large-scale GHPSs.

Future energy and emissions policy scenarios in Ireland for private car transport  

Science Journals Connector (OSTI)

In this paper we use a technological model of Ireland's future car stock to simulate the impact of a range of policy measures on the baseline trend in energy demand in the period to 2030. The policies and measures modelled comprise meeting deployment targets for electric vehicles and compressed natural gas vehicles, an EU regulation for the improvement of vehicle efficiency, implementation of a national biofuel obligation, as well as several behavioural measures (encouraging modal shifting and reduced travel demand). The impact of the different measures simulated is measured in terms of their contribution to meeting Ireland's ambitious targets for energy savings, for renewable energy penetration and for greenhouse gas (GHG) emissions reductions. The results point to a possible improvement of 32% in car stock efficiency, the achievement of 7.8% renewable energy share of road and rail transport and a 22% reduction in non-ETS private car CO2 emissions relative to 2009 levels. A scenario analysis on meeting the EV penetration target shows a significant range of CO2 emissions reductions depending on the cars (and mileage) displaced and on the electricity generation portfolio.

Comparative Analysis of Modeling Studies on China's Future Energy and Emissions Outlook  

SciTech Connect

The past decade has seen the development of various scenarios describing long-term patterns of future Greenhouse Gas (GHG) emissions, with each new approach adding insights to our understanding of the changing dynamics of energy consumption and aggregate future energy trends. With the recent growing focus on China's energy use and emission mitigation potential, a range of Chinese outlook models have been developed across different institutions including in China's Energy Research Institute's 2050 China Energy and CO2 Emissions Report, McKinsey & Co's China's Green Revolution report, the UK Sussex Energy Group and Tyndall Centre's China's Energy Transition report, and the China-specific section of the IEA World Energy Outlook 2009. At the same time, the China Energy Group at Lawrence Berkeley National Laboratory (LBNL) has developed a bottom-up, end-use energy model for China with scenario analysis of energy and emission pathways out to 2050. A robust and credible energy and emission model will play a key role in informing policymakers by assessing efficiency policy impacts and understanding the dynamics of future energy consumption and energy saving and emission reduction potential. This is especially true for developing countries such as China, where uncertainties are greater while the economy continues to undergo rapid growth and industrialization. A slightly different assumption or storyline could result in significant discrepancies among different model results. Therefore, it is necessary to understand the key models in terms of their scope, methodologies, key driver assumptions and the associated findings. A comparative analysis of LBNL's energy end-use model scenarios with the five above studies was thus conducted to examine similarities and divergences in methodologies, scenario storylines, macroeconomic drivers and assumptions as well as aggregate energy and emission scenario results. Besides directly tracing different energy and CO{sub 2} savings potential back to the underlying strategies and combination of efficiency and abatement policy instruments represented by each scenario, this analysis also had other important but often overlooked findings.

Analysis of Potential Energy Saving and CO2 Emission Reduction of Home Appliances and Commercial Equipments in China  

SciTech Connect

China is now the world's largest producer and consumer of household appliances and commercial equipment. To address the growth of electricity use of the appliances, China has implemented a series of minimum energy performance standards (MEPS) for 30 appliances, and voluntary energy efficiency label for 40 products. Further, in 2005, China started a mandatory energy information label that covers 19 products to date. However, the impact of these standard and labeling programs and their savings potential has not been evaluated on a consistent basis. This research involved modeling to estimate the energy saving and CO{sub 2} emission reduction potential of the appliances standard and labeling program for products for which standards are currently in place, or under development and those proposed for development in 2010. Two scenarios that have been developed differ primarily in the pace and stringency of MEPS development. The 'Continued Improvement Scenario' (CIS) reflects the likely pace of post-2009 MEPS revisions, and the likely improvement at each revision step considering the technical limitation of the technology. The 'Best Practice Scenario' (BPS) examined the potential of an achievement of international best practice MEPS in 2014. This paper concludes that under the 'CIS' of regularly scheduled MEPS revisions to 2030, cumulative electricity consumption could be reduced by 9503 TWh, and annual CO{sub 2} emissions would be 16% lower than in the frozen efficiency scenario. Under a 'BPS' scenario for a subset of products, cumulative electricity savings would be 5450 TWh and annual CO{sub 2} emissions reduction would be 35% lower than in the frozen scenario.

Solid Fuel - Oxygen Fired Combustion for Production of Nodular Reduced Iron to Reduce CO2 Emissions and Improve Energy Efficiencies  

SciTech Connect

The current trend in the steel industry is an increase in iron and steel produced in electric arc furnaces (EAF) and a gradual decline in conventional steelmaking from taconite pellets in blast furnaces. In order to expand the opportunities for the existing iron ore mines beyond their blast furnace customer base, a new material is needed to satisfy the market demands of the emerging steel industry while utilizing the existing infrastructure and materials handling capabilities. This demand creates opportunity to convert iron ore or other iron bearing materials to Nodular Reduced Iron (NRI) in a recently designed Linear Hearth Furnace (LHF). NRI is a metallized iron product containing 98.5 to 96.0% iron and 2.5 to 4% C. It is essentially a scrap substitute with little impurity that can be utilized in a variety of steelmaking processes, especially the electric arc furnace. The objective of this project was to focus on reducing the greenhouse gas emissions (GHG) through reducing the energy intensity using specialized combustion systems, increasing production and the use of biomass derived carbon sources in this process. This research examined the use of a solid fuel-oxygen fired combustion system and compared the results from this system with both oxygen-fuel and air-fuel combustion systems. The solid pulverized fuels tested included various coals and a bio-coal produced from woody biomass in a specially constructed pilot scale torrefaction reactor at the Coleraine Minerals Research Laboratory (CMRL). In addition to combustion, the application of bio-coal was also tested as a means to produce a reducing atmosphere during key points in the fusion process, and as a reducing agent for ore conversion to metallic iron to capture the advantage of its inherent reduced carbon footprint. The results from this study indicate that the approaches taken can reduce both greenhouse gas emissions and the associated energy intensity with the Linear Hearth Furnace process for converting iron ore to metallic iron nodules. Various types of coals including a bio-coal produced though torrefaction can result in production of NRI at reduced GHG levels. The process results coupled with earlier already reported developments indicate that this process technique should be evaluated at the next level in order to develop parameter information for full scale process design. Implementation of the process to full commercialization will require a full cost production analysis and comparison to other reduction technologies and iron production alternatives. The technical results verify that high quality NRI can be produced under various operating conditions at the pilot level.

The effects of financial development, economic growth, coal consumption and trade openness on CO2 emissions in South Africa  

Science Journals Connector (OSTI)

Abstract This paper explores the effects of financial development, economic growth, coal consumption and trade openness on environmental performance using time series data over the period 1965–2008 in case of South Africa. The ARDL bounds testing approach to cointegration has been used to test the long run relationship among the variables while short run dynamics have been investigated by applying error correction method (ECM). The unit root properties of the variables are examined by applying Saikkonen and Lütkepohl (2002. Econometric Theory 18, 313–348) structural break unit root test. Our findings confirmed long run relationship among the variables. Results showed that a rise in economic growth increases energy emissions, while financial development reduces it. Coal consumption has significant contribution to deteriorate environment in South African economy. Trade openness improves environmental quality by reducing the growth of energy pollutants. Our empirical results also verified the existence of environmental Kuznets curve. This paper opens up new insights for South African economy to sustain economic growth by controlling environment from degrdation through efficient use of energy.

CO2 Utilization CO2 Utilization Carbon Storage CO2 Utilization Focus Area Carbon dioxide (CO2) utilization efforts focus on pathways and novel approaches for reducing CO2 emissions by developing beneficial uses for the CO2 that will mitigate CO2 emissions in areas where geologic storage may not be an optimal solution. CO2 can be used in applications that could generate significant benefits. It is possible to develop alternatives that can use captured CO2 or convert it to useful products such chemicals, cements, or plastics. Revenue generated from the utilized CO2 could also offset a portion of the CO2 capture cost. Processes or concepts must take into account the life cycle of the process to ensure that additional CO2 is not produced beyond what is already being removed from or going into the atmosphere. Furthermore, while the utilization of CO2 has some potential to reduce greenhouse gas emissions to the atmosphere, CO2 has certain disadvantages as a chemical reactant. Carbon dioxide is rather inert and non-reactive. This inertness is the reason why CO2 has broad industrial and technical applications. Each potential use of CO2 has an energy requirement that needs to be determined; and the CO2 produced to create the energy for the specific utilization process must not exceed the CO2 utilized.

On Leakage from Geologic Storage Reservoirs of CO2  

SciTech Connect

Large amounts of CO2 would need to be injected underground to achieve a significant reduction of atmospheric emissions. The large areal extent expected for CO2 plumes makes it likely that caprock imperfections will be encountered, such as fault zones or fractures, which may allow some CO2 to escape from the primary storage reservoir. Leakage of CO2 could also occur along wellbores. Concerns with escape of CO2 from a primary geologic storage reservoir include (1) acidification of groundwater resources, (2) asphyxiation hazard when leaking CO2 is discharged at the land surface, (3) increase in atmospheric concentrations of CO2, and (4) damage from a high-energy, eruptive discharge (if such discharge is physically possible). In order to gain public acceptance for geologic storage as a viable technology for reducing atmospheric emissions of CO2, it is necessary to address these issues and demonstrate that CO2 can be injected and stored safely in geologic formations.

Synthesis, characterization and performance of single-component CO2-binding organic liquids (CO2BOL) for post combustion CO2 capture  

SciTech Connect

Carbon dioxide (CO2) emission to the atmosphere will increase significantly with the shift to coal powered plants for energy generation. This increase in CO2 emission will contribute to climate change. There is need to capture and sequester large amounts of CO2 emitted from these coal power plants in order to mitigate the environmental effects. Here we report the synthesis, characterization and system performance of multiple third generation CO2 binding organic liquids (CO2BOLs) as a solvent system for post combustion gas capture. Alkanolguanidines and alkanolamidines are single component CO2BOLs that reversibly bind CO2 chemically as liquid zwitterionic amidinium / guanidinium alkylcarbonates. Three different alkanolguanidines and alkanolamidines were synthesized and studied for CO2 capacity and binding energetics. Solvent performance of these three CO2BOLs was evaluated by batch-wise CO2 uptake and release over multiple cycles. Synthesis of CO2BOLs, characterization, CO2 uptake, selectivity towards CO2 as well as solvent tolerance to water will be discussed.

Science Journals Connector (OSTI)

The objective of this study is to describe the complete transport chain of CO2 between capture and storage including a ship transport. This last one is composed by the following steps: Shore terminal including the liquefaction, temporary storage and CO2 loading. Ship with a capacity of 30,000 m3. On or off shore terminal including an unloading system, temporary storage and export towards the final storage. Between all the possible thermodynamic states, the liquid one is most relevant two options are compared in the study (?50 °C, 7 bar) and (?30 °C, 15 bar). The ship has an autonomy of 6 days, is able to cover 1000 km with a cargo of 2.5 Mt/year. Several scenarios are studied varying the geographical position of the CO2 source, the number of harbours and the way the CO2 is finally stored. Depending on the option, the transport cost varies from 24 to 32 €/tCO2. This study confirms the conclusion of a previous study supported by ADEME, the cost transport is not negligible regarding the capture one when ships are considered. Transport by ship becomes a more economical option compared with an off shore pipeline when the distance exceeds 350 km and with an onshore pipeline when it exceeds 1100 km.

Co-benefits of mitigating global greenhouse gas emissions for future air quality and human health  

SciTech Connect

Reducing greenhouse gas (GHG) emissions also influences air quality. We simulate the co-benefits of global GHG reductions on air quality and human health via two mechanisms: a) reducing co-emitted air pollutants, and b) slowing climate change and its effect on air quality. Relative to a reference scenario, global GHG mitigation in the RCP4.5 scenario avoids 0.5±0.2, 1.3±0.6, and 2.2±1.6 million premature deaths in 2030, 2050, and 2100, from changes in fine particulate matter and ozone. Global average marginal co-benefits of avoided mortality are $40-400 (ton CO2)-1, exceeding marginal abatement costs in 2030 and 2050, and within the low range of costs in 2100. East Asian co-benefits are 10-80 times the marginal cost in 2030. These results indicate that transitioning to a low-carbon future might be justified by air quality and health co-benefits.

Different control strategies for a diesel parallel hybrid passenger car were evaluated through numerical simulations. Two different control strategies were analysed: the first focused on fuel consumption minimisation, the second on NOx emissions cuts. Each of these goals was addressed through two different methodologies, the first based on a group of heuristic laws, the second focused on the instantaneous minimisation of a cost function that takes into account both the fuel and battery energies. A first assessment of the potential of a diesel hybrid passenger car as far as fuel consumption and NOx emissions reductions are concerned was obtained.

Novel Co Novel Co 2 - PhiliC AbsorbeNts Summary The ability to separate a high pressure mixture of CO 2 and H 2 such that a high pressure stream of CO 2 for sequestration and a high pressure stream of H 2 for energy are produced remains an elusive goal. This research has identified a class of compounds that melt in the presence of high pressure CO 2 , forming a liquid phase composed of roughly 50wt% CO 2 and 50wt% of the compound. Unlike conventional solvents that require substantial depressurization during regeneration to release a low pressure CO 2 stream, these novel compounds completely release the CO 2 at many hundreds of psia as the compound solidifies. This work will reveal whether one of more of these compounds can selectively remove CO 2 from a mixture

Co Co 2 SequeStration Potential of texaS low-rank CoalS Background Fossil fuel combustion is the primary source of emissions of carbon dioxide (CO 2 ), a major greenhouse gas. Sequestration of CO 2 by injecting it into geologic formations, such as coal seams, may offer a viable method for reducing atmospheric CO 2 emissions. Injection into coal seams has the potential added benefit of enhanced coalbed methane recovery. The potential for CO 2 sequestration in low-rank coals, while as yet undetermined, is believed to differ significantly from that for bituminous coals. To evaluate the feasibility and the environmental, technical, and economic impacts of CO 2 sequestration in Texas low-rank coal beds, the Texas Engineering Experimental Station is conducting a four-year study

On the causal dynamics between economic growth, renewable energy consumption, CO2 emissions and trade openness: Fresh evidence from BRICS countries  

Science Journals Connector (OSTI)

Abstract The current study investigates the causal relationship between economic growth and renewable energy consumption in the BRICS countries over the period 1971–2010 within a multivariate framework. The ARDL bounds testing approach to cointegration and vector error correction model (VECM) are used to examine the long-run and causal relationships between economic growth, renewable energy consumption, trade openness and carbon dioxide emissions. Empirical evidence shows that, based on the ARDL estimates, there exist long-run equilibrium relationships among the competing variables. Regarding the VECM results, bi-directional Granger causality exists between economic growth and renewable energy consumption, suggesting the feedback hypothesis, which can explain the role of renewable energy in stimulating economic growth in BRICS countries.

Efficiency of Sequestrating CO Efficiency of Sequestrating CO 2 in the Ocean Richard Dewey (RDewey@uvic.ca ; 250-472-4009) University of Victoria, P.O.

The ocean, and ultimately ocean sediments, naturally represents the single largest sink of CO 2 , and annually sequesters several gigatons of carbon from the atmosphere.

CO2 interaction with geomaterials.  

SciTech Connect

This work compares the sorption and swelling processes associated with CO2-coal and CO2-clay interactions. We investigated the mechanisms of interaction related to CO2 adsortion in micropores, intercalation into sub-micropores, dissolution in solid matrix, the role of water, and the associated changes in reservoir permeability, for applications in CO2 sequestration and enhanced coal bed methane recovery. The structural changes caused by CO2 have been investigated. A high-pressure micro-dilatometer was equipped to investigate the effect of CO2 pressure on the thermoplastic properties of coal. Using an identical dilatometer, Rashid Khan (1985) performed experiments with CO2 that revealed a dramatic reduction in the softening temperature of coal when exposed to high-pressure CO2. A set of experiments was designed for -20+45-mesh samples of Argonne Premium Pocahontas No.3 coal, which is similar in proximate and ultimate analysis to the Lower Kittanning seam coal that Khan used in his experiments. No dramatic decrease in coal softening temperature has been observed in high-pressure CO2 that would corroborate the prior work of Khan. Thus, conventional polymer (or 'geopolymer') theories may not be directly applicable to CO2 interaction with coals. Clays are similar to coals in that they represent abundant geomaterials with well-developed microporous structure. We evaluated the CO2 sequestration potential of clays relative to coals and investigated the factors that affect the sorption capacity, rates, and permanence of CO2 trapping. For the geomaterials comparison studies, we used source clay samples from The Clay Minerals Society. Preliminary results showed that expandable clays have CO2 sorption capacities comparable to those of coal. We analyzed sorption isotherms, XRD, DRIFTS (infrared reflectance spectra at non-ambient conditions), and TGA-MS (thermal gravimetric analysis) data to compare the effects of various factors on CO2 trapping. In montmorillonite, CO2 molecules may remain trapped for several months following several hours of exposure to high pressure (supercritical conditions), high temperature (above boiling point of water) or both. Such trapping is well preserved in either inert gas or the ambient environment and appears to eventually result in carbonate formation. We performed computer simulations of CO2 interaction with free cations (normal modes of CO2 and Na+CO2 were calculated using B3LYP / aug-cc-pVDZ and MP2 / aug-cc-pVDZ methods) and with clay structures containing interlayer cations (MD simulations with Clayff potentials for clay and a modified CO2 potential). Additionally, interaction of CO2 with hydrated Na-montmorillonite was studied using density functional theory with dispersion corrections. The sorption energies and the swelling behavior were investigated. Preliminary modeling results and experimental observations indicate that the presence of water molecules in the interlayer region is necessary for intercalation of CO2. Our preliminary conclusion is that CO2 molecules may intercalate into interlayer region of swelling clay and stay there via coordination to the interlayer cations.

CO2 Sequestration short course  

SciTech Connect

Given the public’s interest and concern over the impact of atmospheric greenhouse gases (GHGs) on global warming and related climate change patterns, the course is a timely discussion of the underlying geochemical and mineralogical processes associated with gas-water-mineral-interactions encountered during geological sequestration of CO2. The geochemical and mineralogical processes encountered in the subsurface during storage of CO2 will play an important role in facilitating the isolation of anthropogenic CO2 in the subsurface for thousands of years, thus moderating rapid increases in concentrations of atmospheric CO2 and mitigating global warming. Successful implementation of a variety of geological sequestration scenarios will be dependent on our ability to accurately predict, monitor and verify the behavior of CO2 in the subsurface. The course was proposed to and accepted by the Mineralogical Society of America (MSA) and The Geochemical Society (GS).

Northern California CO2 Reduction Project  

SciTech Connect

C6 Resources LLC, a wholly owned subsidiary of Shell Oil Company, worked with the US Department of Energy (DOE) under a Cooperative Agreement to develop the Northern California CO2 Reduction Project. The objective of the Project is to demonstrate the viability of using Carbon Capture and Sequestration (CCS) to reduce existing greenhouse gas emissions from industrial sources on a large-scale. The Project will capture more than 700,000 metric tonnes of CO2 per year, which is currently being vented to the atmosphere from the Shell Martinez Refinery in Contra Costa County. The CO2 will be compressed and dehydrated at the refinery and then transported via pipeline to a sequestration site in a rural area in neighboring Solano County. The CO2 will be sequestered into a deep saline formation (more than two miles underground) and will be monitored to assure secure, long-term containment. The pipeline will be designed to carry as much as 1,400,000 metric tonnes of CO2 per year, so additional capacity will be available to accommodate CO2 captured from other industrial sources. The Project is expected to begin operation in 2015. The Project has two distinct phases. The overall objective of Phase 1 was to develop a fully definitive design basis for the Project. The Cooperative Agreement with the DOE provided cost sharing for Phase 1 and the opportunity to apply for additional DOE cost sharing for Phase 2, comprising the design, construction and operation of the Project. Phase 1 has been completed. DOE co-funding is provided by the American Recovery and Reinvestment Act (ARRA) of 2009. As prescribed by ARRA, the Project will stimulate the local economy by creating manufacturing, transportation, construction, operations, and management jobs while addressing the need to reduce greenhouse gas emissions at an accelerated pace. The Project, which will also assist in meeting the CO2 reduction requirements set forth in California?s Climate Change law, presents a major opportunity for both the environment as well as the region. C6 Resources is conducting the Project in collaboration with federally-funded research centers, such as Lawrence Berkeley National Lab and Lawrence Livermore National Lab. C6 Resources and Shell have identified CCS as one of the critical pathways toward a worldwide goal of providing cleaner energy. C6 Resources, in conjunction with the West Coast Regional Carbon Sequestration Partnership (WESTCARB), has conducted an extensive and ongoing public outreach and CCS education program for local, regional and state-wide stakeholders. As part of a long term relationship, C6 Resources will continue to engage directly with community leaders and residents to ensure public input and transparency. This topical report summarizes the technical work from Phase 1 of the Project in the following areas: ? Surface Facility Preliminary Engineering: summarizes the preliminary engineering work performed for CO2 capture, CO2 compression and dehydration at the refinery, and surface facilities at the sequestration site ? Pipeline Preliminary Engineering: summarizes the pipeline routing study and preliminary engineering design ?

Integrated Energy System with Beneficial Carbon Dioxide (CO2) Use  

SciTech Connect

To address the public concerns regarding the consequences of climate change from anthropogenic carbon dioxide (CO2) emissions, the U.S. Department of Energy National Energy Technology Laboratory (DOE-NETL) is actively funding a CO2 management program to develop technologies capable of reducing the CO2 emissions from fossil fuel power plants and other industrial facilities. Over the past decade, this program has focused on reducing the costs of carbon capture and storage technologies. Recently, DOE-NETL launched an alternative CO2 mitigation program focusing on beneficial CO2 reuse and supporting the development of technologies that mitigate emissions by converting CO2 to solid mineral form that can be utilized for enhanced oil recovery, in the manufacturing of concrete or as a benign landfill, in the production of valuable chemicals and/or fuels. This project was selected as a CO2 reuse activity which would conduct research and development (R&D) at the pilot scale via a cost-shared Cooperative Agreement number DE-FE0001099 with DOE-NETL and would utilize funds setaside by the American Recovery and Reinvestment Act (ARRA) of 2009 for Industrial Carbon Capture and Sequestration R&D,

Low-Pressure Membrane Contactors for CO2 Capture Low-Pressure Membrane Contactors for CO2 Capture Project No.: DE-FE0007553 Membrane Technology and Research, Inc. (MTR) is developing a new type of membrane contactor (or mega-module) to separate carbon dioxide (CO2) from power plant flue gas. This module's membrane area is 500 square meters, 20 to 25 times larger than that of current modules used for CO2 capture. A 500-MWe coal power plant requires 0.5 to 1 million square meters of membrane to achieve 90 percent CO2 capture. The new mega-modules can drastically reduce the cost, complexity, and footprint of commercial-scale membrane module integration. Energy savings due to low-pressure drops for gases circulated through the modules, as well as improved countercurrent flow, are additional benefits. The feasibility of using mega-modules in several different hybrid process designs is being evaluated for future development potential.

Implementation of the El Mar (Delaware) Unit CO2 flood  

SciTech Connect

Union Royalty, Inc., Amoco Production Company, and Enron Liquids Pipeline Company recently announced that they have commenced operations of an innovative enhanced oil recovery project at the El Mar (Delaware) Unit in Loving County, Texas, about 100 miles west of Midland, Texas. The project will convert the unit`s existing oil recovery system from a secondary (waterflood) system to a tertiary (CO2 flood) system designed to use carbon dioxide and water to increase crude oil production from the unit. What makes this EOR project unique is the creative deal structured by the partners involved. Amoco, Union Royalty, and Enron have worked out an unprecedented arrangement whereby Amoco essentially trades CO2 for an interest in Union Royalty`s future oil production from the unit. By pioneering this innovative deal new production life has been restored to a field that otherwise might dry up. Enron is participating in the project by transporting CO2 to the unit via a 40-mile expansion of its Central Basin Pipeline system from the Dollarhide oil field in Andrews county, Texas. The project will be implemented in four phases. The first phase in operation today comprises seven CO2 injection wells which have begun to process the reservoir with CO2. Plans now call for more CO2 injectors to be installed during the next three to five years until a total of 65 CO2 injectors and an on-site CO2 compression facility serve the unit`s 70 production wells.

Carbon dioxide emission reduction using molten carbonate fuel cell systems  

Science Journals Connector (OSTI)

Abstract The contribution of the molten carbonate fuel cell system (MCFCs) to carbon dioxide (CO2) emission reduction in power application is analyzed. \\{MCFCs\\} can separate and concentrate CO2 emitted from traditional thermal power plants (PPs) without reducing the plant's overall energy efficiency. \\{MCFCs\\} can also be used by itself as an effective CO2 separator or concentrator by managing the anode gas stream to increase the heat utilization of the system. The CO2 separated and concentrated by \\{MCFCs\\} is most effectively captured by condensation. \\{MCFCs\\} is currently used as a CO2 separator only to a limited extent due to its high cost and relatively small scale operation. However, \\{MCFCs\\} will substantially contribute to reduce CO2 emissions in power generation applications in the near future.

Industrial CO2 Removal: CO2 Capture from Ambient Air and Geological Sequestration  

SciTech Connect

This abstract and its accompanying presentation will provide an overview of two distinct industrial processes for removing carbon dioxide (CO2) from the atmosphere as a means of addressing anthropogenic climate change. The first of these is carbon dioxide capture and storage (CCS) coupled with large scale biomass production (hereafter referred to as bioCCS). The second is CO2 capture from ambient air via industrial systems (hereafter referred to as direct air capture (DAC)). In both systems, the captured CO2 would be injected into deep geologic formations so as to isolate it from the atmosphere. The technical literature is clear that both of these technologies are technically feasible as of today (IPCC, 2005; Keith, 2009; Lackner, 2009; Luckow et al., 2010; Ranjan and Herzog, 2011). What is uncertain is the relative cost of these industrial ambient-air CO2 removal systems when compared to other emissions mitigation measures, the ultimate timing and scale of their deployment, and the resolution of potential site specific constraints that would impact their ultimate commercial deployment.

Feed Systems Feed Systems Coal-CO2 Slurry Feeding System for Pressurized Gasifiers Massachusetts Institute of Technology Project Number: FE0012500 Project Description This project will develop and assess a slurry feeding system based on a suspension of coal in liquid CO2 that can be pumped into a high-pressure gasifier. The advantages of this solution are that CO2 has a low heat capacity, a low heat of vaporization and low viscosity. Thus, the liquid CO2 imposes a much smaller thermal load on the gasifier relative to a water slurry, and has the potential to improve the efficiency and economics of integrated gasification combined cycle (IGCC) power plants with carbon capture and dramatically reduce greenhouse gas emissions from coal fired power plants.

Assessment of CO2 capture options from various points in steam methane reforming for hydrogen production  

Science Journals Connector (OSTI)

Abstract Steam methane reforming (SMR) is currently the main hydrogen production process in industry, but it has high emissions of CO2, at almost 7 kg CO2/kg H2 on average, and is responsible for about 3% of global industrial sector CO2 emissions. Here, the results are reported of an investigation of the effect of steam-to-carbon ratio (S/C) on CO2 capture criteria from various locations in the process, i.e. synthesis gas stream (location 1), pressure swing adsorber (PSA) tail gas (location 2), and furnace flue gases (location 3). The CO2 capture criteria considered in this study are CO2 partial pressure, CO2 concentration, and CO2 mass ratio compared to the final exhaust stream, which is furnace flue gases. The CO2 capture number (Ncc) is proposed as measure of capture favourability, defined as the product of the three above capture criteria. A weighting of unity is used for each criterion. The best S/C ratio, in terms of providing better capture option, is determined. CO2 removal from synthesis gas after the shift unit is found to be the best location for CO2 capture due to its high partial pressure of CO2. However, furnace flue gases, containing almost 50% of the CO2 in produced in the process, are of great significance environmentally. Consequently, the effects of oxygen enrichment of the furnace feed are investigated, and it is found that this measure improves the CO2 capture conditions for lower S/C ratios. Consequently, for an S/C ratio of 2.5, CO2 capture from a flue gas stream is competitive with two other locations provided higher weighting factors are considered for the full presence of CO2 in the flue gases stream. Considering carbon removal from flue gases, the ratio of hydrogen production rate and Ncc increases with rising reformer temperature.

PLAINS CO2 REDUCTION (PCOR) PARTNERSHIP  

SciTech Connect

During the period of October 1, 2003, through September 30, 2005, the Plains CO2 Reduction (PCOR) Partnership, identified geologic and terrestrial candidates for near-term practical and environmentally sound carbon dioxide (CO2) sequestration demonstrations in the heartland of North America. The PCOR Partnership region covered nine states and three Canadian provinces. The validation test candidates were further vetted to ensure that they represented projects with (1) commercial potential and (2) a mix that would support future projects both dependent and independent of CO2 monetization. This report uses the findings contained in the PCOR Partnership's two dozen topical reports and half-dozen fact sheets as well as the capabilities of its geographic information system-based Decision Support System to provide a concise picture of the sequestration potential for both terrestrial and geologic sequestration in the PCOR Partnership region based on assessments of sources, sinks, regulations, deployment issues, transportation, and capture and separation. The report also includes concise action plans for deployment and public education and outreach as well as a brief overview of the structure, development, and capabilities of the PCOR Partnership. The PCOR Partnership is one of seven regional partnerships under Phase I of the U.S. Department of Energy National Energy Technology Laboratory's Regional Carbon Sequestration Partnership program. The PCOR Partnership, comprising 49 public and private sector members, is led by the Energy & Environmental Research Center at the University of North Dakota. The international PCOR Partnership region includes the Canadian provinces of Alberta, Saskatchewan, and Manitoba and the states of Montana (part), Wyoming (part), North Dakota, South Dakota, Nebraska, Missouri, Iowa, Minnesota, and Wisconsin.

Field Emission in CEBAF's SRF Cavities and Implications for Future Accelerators  

SciTech Connect

Field emission is one of the key issues in superconducting RF for particle accelerators. When present, it limits operating gradient directly or via induced heat load at 2K. In order to minimize particulate contamination of and thus field emission in the CEBAF SRF cavities during assembly, a cold ceramic RF window was placed very close to the accelerating cavity proper. As an unintended consequence of this, the window is charged by field-emitted electrons, making it possible to monitor and model field emission in the CEBAF cavities since in-tunnel operation began. From January 30, 1995, through February 10, 2003, there were 64 instances of spontaneous onset or change in cavity field emission with a drop in usable gradient averaging 1.4 ({sigma} 0.8) MV/m at each event. Fractional loss averaged 0.18 ({sigma} 0.12) of pre-event gradient. This event count corresponds to 2.4 events per century per cavity, or 8 per year in CEBAF. It is hypothesized that changes in field emission are due to adsorbed gas accumulation. The possible implications of this and other observations for the International Linear Collider (ILC) and other future accelerators will be discussed.

RESTRUCTURING OF THE JORDANIAN UTILITY SECTOR AND ITS ASSOCIATED GHG EMISSIONS: A FUTURE PROJECTION  

Science Journals Connector (OSTI)

As a small non?oil producing Middle Eastern country of a young and growing population and rapid urbanization Jordan like many countries all over the world was and is still facing the problem of meeting the rapidly increasing demand of electricity. The main objective of this study is to review many current aspects of the Jordanian electricity sector including electricity generation electricity consumption energy related emissions and future possibilities based on time series forecasting through the term of the Clean Development Mechanism (CDM) arrangement under the Kyoto Protocol in which the Hashemite Kingdom of Jordan had signed lately which allows industrialized countries with a greenhouse gas reduction commitment to invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries. Several scenarios are proposed in this study based on projected electricity consumption data until year 2028. Without attempting to replace the currently existing fossil?fuel based power plant technologies in Jordan by clean ones electricity consumption and associated GHG emissions are predicted to rise by 138% by year 2028; however if new clean technologies are adopted gradually over the same period electricity consumption as well as GHG emissions will ascend at a lower rate.

COMPARISON OF THREE METHODS TO PROJECT FUTURE BASELINE CARBON EMISSIONS IN TEMPERATE RAINFOREST, CURINANCO, CHILE  

SciTech Connect

Deforestation of temperate rainforests in Chile has decreased the provision of ecosystem services, including watershed protection, biodiversity conservation, and carbon sequestration. Forest conservation can restore those ecosystem services. Greenhouse gas policies that offer financing for the carbon emissions avoided by preventing deforestation require a projection of future baseline carbon emissions for an area if no forest conservation occurs. For a proposed 570 km{sup 2} conservation area in temperate rainforest around the rural community of Curinanco, Chile, we compared three methods to project future baseline carbon emissions: extrapolation from Landsat observations, Geomod, and Forest Restoration Carbon Analysis (FRCA). Analyses of forest inventory and Landsat remote sensing data show 1986-1999 net deforestation of 1900 ha in the analysis area, proceeding at a rate of 0.0003 y{sup -1}. The gross rate of loss of closed natural forest was 0.042 y{sup -1}. In the period 1986-1999, closed natural forest decreased from 20,000 ha to 11,000 ha, with timber companies clearing natural forest to establish plantations of non-native species. Analyses of previous field measurements of species-specific forest biomass, tree allometry, and the carbon content of vegetation show that the dominant native forest type, broadleaf evergreen (bosque siempreverde), contains 370 {+-} 170 t ha{sup -1} carbon, compared to the carbon density of non-native Pinus radiata plantations of 240 {+-} 60 t ha{sup -1}. The 1986-1999 conversion of closed broadleaf evergreen forest to open broadleaf evergreen forest, Pinus radiata plantations, shrublands, grasslands, urban areas, and bare ground decreased the carbon density from 370 {+-} 170 t ha{sup -1} carbon to an average of 100 t ha{sup -1} (maximum 160 t ha{sup -1}, minimum 50 t ha{sup -1}). Consequently, the conversion released 1.1 million t carbon. These analyses of forest inventory and Landsat remote sensing data provided the data to evaluate the three methods to project future baseline carbon emissions. Extrapolation from Landsat change detection uses the observed rate of change to estimate change in the near future. Geomod is a software program that models the geographic distribution of change using a defined rate of change. FRCA is an integrated spatial analysis of forest inventory, biodiversity, and remote sensing that produces estimates of forest biodiversity and forest carbon density, spatial data layers of future probabilities of reforestation and deforestation, and a projection of future baseline forest carbon sequestration and emissions for an ecologically-defined area of analysis. For the period 1999-2012, extrapolation from Landsat change detection estimated a loss of 5000 ha and 520,000 t carbon from closed natural forest; Geomod modeled a loss of 2500 ha and 250 000 t; FRCA projected a loss of 4700 {+-} 100 ha and 480,000 t (maximum 760,000 t, minimum 220,000 t). Concerning labor time, extrapolation for Landsat required 90 actual days or 120 days normalized to Bachelor degree level wages; Geomod required 240 actual days or 310 normalized days; FRCA required 110 actual days or 170 normalized days. Users experienced difficulties with an MS-DOS version of Geomod before turning to the Idrisi version. For organizations with limited time and financing, extrapolation from Landsat change provides a cost-effective method. Organizations with more time and financing could use FRCA, the only method where that calculates the deforestation rate as a dependent variable rather than assuming a deforestation rate as an independent variable. This research indicates that best practices for the projection of baseline carbon emissions include integration of forest inventory and remote sensing tasks from the beginning of the analysis, definition of an analysis area using ecological characteristics, use of standard and widely used geographic information systems (GIS) software applications, and the use of species-specific allometric equations and wood densities developed for local species.

Novel Electrochemical CO2 Removal Technology For Combustion of Fossil-Fuels  

SciTech Connect

Electrochemical gas separation concepts are often neglected when discussing options to manage CO2 emissions. Electrochemical approaches are selective and do not require periodic regeneration. This paper will review prior work on electrochemical CO2 separation and compare the parasitic energy penalties of this approach to more conventional approaches of capturing CO2 from flue gas streams. A new concept to reduce the electrochemical parasitic energy penalties will be introduced and a preliminary analysis of the concept will be discussed. Relative to a conventional monoethanolamine (MEA) solvent approach, electrochemical CO2 capture does require less energy on a per-mole-of-CO2 basis. However, there are trade-offs since an electrochemical pumping approach requires electrical energy, instead of lower grade thermal energy. Although there are several issues with electrochemical CO2 capture, efforts to reduce parasitic losses of CO2 separation may need to consider such novel alternatives.

CO2 laser frequency multiplication  

SciTech Connect

The duration of the mode-locked CO(2) laser pulses was measured to be 0.9 + or - nsec by the technique of (second harmonic) autocorrelation. Knowing the pulse duration, the spot size, and the harmonic conversion efficiency, a detailed fit of experiment to theory gave an estimate of the nonlinear coefficient of AgGaSe(2). d36 = 31 + or - V(1), in agreement with the most accurate literature values. A number of experiments were made with longer pulse trains in which the highest harmonic energy conversion reached 78%. The damage threshold was measured and it turned out to be related much more strongly to fluence than intensity. The shorter pulse trains had peak intensities of close to 300 MW 1/cm squared whereas the longer trains (3 usec) had intensities up to 40 MW 1/cm squared.

NETL: Ion Advanced Solvent CO2 Capture Pilot Project  

NLE Websites -- All DOE Office Websites (Extended Search)

Ion Advanced Solvent CO2 Capture Pilot Project Ion Advanced Solvent CO2 Capture Pilot Project Project No.: DE-FE0013303 ION Engineering is conducting small pilot-scale (~ 0.7 MW) testing of an advanced CO2 capture solvent technology that has previously undergone bench-scale testing. The small pilot-scale testing will involve continuous long-term operation in order to gather the necessary data ultimately required for further scale-up. Activities will include the design and fabrication of the 0.5-0.7 MWe (equivalent) slipstream pilot plant; scale-up of solvent manufacturing; testing, data collection, and analysis of solvent performance; degradation and air emission analysis; modeling and simulation for the detailed preliminary and final techno-economic analyses; and decommissioning of pilot plant equipment upon completion of solvent testing. The advanced solvent is anticipated to have significant operating and capital cost advantages over other solvents currently in development. Advantages include significant reductions in parasitic load and liquid flow rates which directly translate to smaller more efficient CO2 capture processes. Make-up water and amine emissions rates will be examined during this project. There is the potential that additional solvent, system, and integration savings will be identified, which could result in further operating and capital cost reductions.

Reducing CO2 in the transport sector in Japan  

Science Journals Connector (OSTI)

In this paper, we have investigated the cost-effectiveness of alternative fuel vehicles as a measure for CO2 reduction. Computed results indicate that the installation of alternative fuel vehicles is much more expensive than fuel switching in industry or the power generation sector. However, some economic incentives will make the price go down to the level at which alternative fuel vehicles are competitive with conventional vehicles. At the same time, mass production makes their prices go down although it is rather expensive at present. Then, we developed the scenarios in which CO2 emissions could be stabilised at the level in 1990. In the higher demand case (1.2%/yr.), it is indispensable to introduce alternative fuel vehicles into the market. Our model selects electric vehicles and compressed natural gas vehicles as cost-effective options. In the scenario where carbon tax revenue is not offset by subsidy, we have to impose prohibitively high carbon tax to suppress CO2. However, CO2 emission can be suppressed by a reasonable carbon tax if the tax revenue is returned to the market to subsidise alternative fuel vehicles and their infrastructures.

CO2 Sequestration in Basalt Formations  

NLE Websites -- All DOE Office Websites (Extended Search)

CO CO 2 SequeStratiOn in BaSalt FOrmatiOnS Background There is growing concern that buildup of greenhouse gases, especially carbon dioxide (CO 2 ), in the atmosphere is contributing to global climate change. One option for mitigating this effect is to sequester CO 2 in geologic formations. Numerous site assessments for geologic sequestration of CO 2 have been conducted in virtually every region of the United States. For the most part, these studies have involved storing CO 2 in saline formation, deep coal seams, and depleted oil and gas reservoirs. Another option, however, is basalt formations. Basalt is a dark-colored, silica-rich, volcanic rock that contains cations-such as calcium, magnesium, and iron-that can combine with CO 2 to form carbonate minerals. Basalt formations have not received much

Risk Assessment and Monitoring of Stored CO2 in Organic Rocks Under Non-Equilibrium Conditions  

SciTech Connect

The USA is embarking upon tackling the serious environmental challenges posed to the world by greenhouse gases, especially carbon dioxide (CO2). The dimension of the problem is daunting. In fact, according to the Energy Information Agency, nearly 6 billion metric tons of CO2 were produced in the USA in 2007 with coal-burning power plants contributing about 2 billion metric tons. To mitigate the concerns associated with CO2 emission, geological sequestration holds promise. Among the potential geological storage sites, unmineable coal seams and shale formations in particular show promise because of the probability of methane recovery while sequestering the CO2. However. the success of large-scale sequestration of CO2 in coal and shale would hinge on a thorough understanding of CO2's interactions with host reservoirs. An important parameter for successful storage of CO2 reservoirs would be whether the pressurized CO2 would remain invariant in coal and shale formations under reasonable internal and/or external perturbations. Recent research has brought to the fore the potential of induced seismicity, which may result in caprock compromise. Therefore, to evaluate the potential risks involved in sequestering CO2 in Illinois bituminous coal seams and shale, we studied: (i) the mechanical behavior of Murphysboro (Illinois) and Houchin Creek (Illinois) coals, (ii) thermodynamic behavior of Illinois bituminous coal at - 100oC ? T ? 300oC, (iii) how high pressure CO2 (up to 20.7 MPa) modifies the viscosity of the host, (iv) the rate of emission of CO2 from Illinois bituminous coal and shale cores if the cores, which were pressurized with high pressure (? 20.7 MPa) CO2, were exposed to an atmospheric pressure, simulating the development of leakage pathways, (v) whether there are any fractions of CO2 stored in these hosts which are resistance to emission by simply exposing the cores to atmospheric pressure, and (vi) how compressive shockwaves applied to the coal and shale cores, which were pressurized with high pressure CO2, determine the fate of sequestered CO2 in these cores. Our results suggested that Illinois bituminous coal in its unperturbed state, i.e., when not pressurized with CO2, showed large variations in the mechanical properties. Modulus varied from 0.7 GPa to 3.4 GPa even though samples were extracted from a single large chunk of coal. We did not observe any glass transition for Illinois bituminous coal at - 100oC ? T ? 300oC, however, when the coal was pressurized with CO2 at ambient ? P ? 20.7 MPa, the viscosity of the coal decreased and inversely scaled with the CO2 pressure. The decrease in viscosity as a function of pressure could pose CO2 injection problems for coal as lower viscosity would allow the solid coal to flow to plug the fractures, fissures, and cleats. Our experiments also showed a very small fraction of CO2 was absorbed in coal; and when CO2 pressurized coals were exposed to atmospheric conditions, the loss of CO2 from coals was massive. Half of the sequestered gas from the coal cores was lost in less than 20 minutes. Our shockwave experiments on Illinois bituminous coal, New Albany shale (Illinois), Devonian shale (Ohio), and Utica shale (Ohio) presented clear evidence that the significant emission of the sequestered CO2 from these formations cannot be discounted during seismic activity, especially if caprock is compromised. It is argued that additional shockwave studies, both compressive and transverse, would be required for successfully mapping the risks associated with sequestering high pressure CO2 in coal and shale formations.

Upper bound of polymeric membranes for mixed-gas CO2/CH4 separations  

Science Journals Connector (OSTI)

Abstract Membrane polymers with high permeability and high selectivity are preferred for gas separations. However, there exists a trade-off or upper bound, i.e., polymers with higher permeability often exhibit lower selectivity, and vice versa. The upper bound for separation of various gas pairs has been empirically drawn and theoretically rationalized using pure-gas data. However, for CO2/CH4 separation, the high pressure CO2 and non-methane hydrocarbons can plasticize polymers, increasing mixed-gas CO2 permeability and decreasing mixed-gas CO2/CH4 selectivity. This study aims to apply a modified free volume theory to interpret CO2/CH4 separation performance in polymeric membranes. The model satisfactorily describes the pure-gas upper bounds for various gas pairs including CO2/CH4, the effect of high pressure CO2 on mixed-gas CO2/CH4 separation properties, and the practical mixed-gas upper bound for CO2/CH4 separations. The CO2 is found to have an estimated glass transition temperature of 108 K. The assumptions of this model are discussed, and future work to improve this model is proposed.

9 - Oxyfuel combustion systems and technology for carbon dioxide (CO2) capture in power plants  

Science Journals Connector (OSTI)

Abstract: Oxyfuel combustion uses pure oxygen instead of air to burn carbonaceous materials, resulting in a CO2 separation efficiency theoretically close to 100 % should the fuel and oxygen be free of contaminants. This chapter examines several oxyfuel systems, considering two categories of power cycle – those based on steam cycles and those based on gas cycles – both of which generate oxygen using a cryogenic air separation unit. Also covered is the AZEP cycle, which belongs in the second category but which uses a ceramic membrane integrated into the system to separate oxygen from air. Oxy-combustion in IGCC plants and in gas turbine cycles integrating solid oxide fuel cells is also examined here as a low emission process. The technical issues and future potential for each option are discussed and reference is made to several pilot installations and ongoing R & D projects.

Options for CO2-lean hydrogen export from Norway to Germany  

Science Journals Connector (OSTI)

Norway is a nation with an abundant supply of energy, both from fossil and renewable resources. Due to limited domestic demand, Norway is today exporting large amounts of petroleum products. For the future, various options for export of CO2-lean energy exist, both from Northern and Southern Norway, and both from fossil sources (including carbon capture and storage), and renewable energies (particularly wind power). Transport vectors are hydrogen pipelines, liquid hydrogen ships and HVDC cables, and a plausible customer is central Europe due to its proximity, high population density and lack of domestic energy resources. Within the framework of the “NorWays” project, various options to deliver energy for hydrogen-based transportation from Norway to Germany were studied. Eight CO2-lean well-to-wheel energy export chains were evaluated with respect to efficiency, GHG emissions and other environmental impacts, costs and utilisation of Norwegian R&D experience. In the chosen scenarios, energy export via hydrogen pipelines and ships appeared energetically and economically interesting against existing approaches as NG and electricity export. Furthermore, increased utilisation of Norwegian R&D experience and higher value creation is anticipated by the export of a higher refined product.

(Denmark comparison is 1972 and 1991) With the third Conference of the Parties (COP-3) in Kyoto approaching, there is a great deal of excitement over policies designed to reduce future carbon dioxide (CO2) emissions from fossil fuels. At COP-3, more than 130 nations will meet to create legally binding targets for CO2 reductions. Accordingly, we have analyzed the patterns of emissions arising from the end uses of energy (and electricity production) in ten industrialized countries, with surprising and, in some cases, worrisome results. The surprise is that emissions in many countries in the early 1990s were lower than in the 1970s in an absolute sense and on a per capita basis; the worry

Forecast of Advanced Technology for Coal Power Generation Towards the Year of 2050 in CO2 Reduction Model of Japan  

Science Journals Connector (OSTI)

Abstract In the fossil fuel, coal is enough to get easily because it has supply and price stability brought about its ubiquitously. Coal is used for power generation as the major fuel in the world. However it is true that control of global warming should be applied to coal power generations. Therefore, many people expect CO2 reduction by technical innovation such as efficiency improvement, Carbon dioxide Capture and Storage (CCS). In case of coal power plant are considered for improving efficiency. Some of them have already put into commercial operation but others are still under R&D stage. Especially, the technical development prospect of the power plant is very important for planning the energy strategy in the resource-importing country. Japan Coal Energy Center (JCOAL) constructed a program to forecast the share of advanced coal fired plants/natural gas power plants towards the year of 2050. Then, we simulated the future prediction about 2 cases (the Japanese scenario and the world scenario). The fuel price and the existence of CCS were considered in the forecast of the technical development of the thermal power generation. Especially in the Japanese scenario, we considered the CO2 reduction target which is 80% reduction in 1990. In the world scenario, coal price had almost no influence on the share of coal fired plant. However, when the gas price increased 1.5% or more, the share of coal fired plant increased. In that case, CO2 emissions increased because coal-fired plant increased. Compared with both cases, the amount of CO2 in 2050 without CCS case was 50% higher than that of with CCS case. In Japanese scenario, achievement of 80% CO2 reduction target is impossible without CCS. If CCS is introduced into all the new establishment coal fired plant, CO2 reduction target can be attained. In the Japanese scenario, the gas price more expensive than a coal price so that the amount of the coal fired plant does not decline. Since the reduction of the amount of CO2 will be needed in all over the world, introductory promotion and technical development of CCS are very important not only Japan but also all over the world.

Environmental impact and techno-economic analysis of the coal gasification process with/without CO2 capture  

Science Journals Connector (OSTI)

Abstract Coal gasification, the technology for high-efficient utilization of coal, has been widely used in China. However, it suffers from high CO2 emissions problem due to the carbon-rich character of coal. To reduce CO2 emissions, different CO2 capture technologies are developed and integrated into the coal gasification based processes. However, involving CO2 capture would result in energetic and economic penalty. This paper analyses three cases of coal gasification processes from environmental, technical, and economical points of view. These processes are (1) a conventional coal gasification process; (2) a coal gasification process with CO2 capture and sequestration, in which CO2 is stored by mineral sequestration; (3) a coal gasification process with CO2 capture and utilization, in which CO2 is reused to produce syngas. The results show that the coal gasification process with CO2 capture and sequestration has advantage only in environmental aspect compared to the conventional process. The process with CO2 capture and utilization has advantages in both technical and environmental aspects while disadvantage in economic aspect. However, if the carbon tax higher than 15 USD/t CO2 is introduced, this disadvantage will be negligible.

Chapter 19 - Smart Energy Houses of the Future – Self-supporting in Energy and Zero Emission  

Science Journals Connector (OSTI)

Publisher Summary The energy-efficient design of buildings leans heavily on traditional methods, as developed by our ancestors; they are fundamental, sustainable concepts that exploit natural means to provide the interior microclimates for our living and working areas. The principles used today for low-energy building design are highly constrained by the needs of the housing market, national building codes and other restrictions that our ancestors never faced; available sites often do not allow free orientation or use of natural shade, lightweight construction avoids thermal mass, and generally the economics of house building tends towards minimum performance standards. Construction technology over the centuries has progressed from the provision of basic shelter and security to sophisticated city buildings capable of providing an indoor environment that is nowadays taken for granted: warmth, light and abundant energy, all in opposition to the natural climate. New residential buildings are being built to constantly improving energy efficiency standards, although internationally these standards vary widely. With the construction and operation of buildings accounting for some 40% of total carbon emissions in most developed countries, it is clear these standards will be tightened in future years to minimize energy consumption. The zero-energy house can be realized technically, and today, highly insulated and virtually airtight residences built to Passive House standards are being demonstrated; the demand for space heating in these buildings can be less than that for the hot water. There are at least three areas where ongoing developments in technology promise improved energy utilization efficiency in housing, these being heat pumps, combined heat and power (CHP), and advanced materials.

Interactions between measures for the support of electricity from renewable energy sources and CO2 mitigation  

Science Journals Connector (OSTI)

As Europe wants to move towards a secure, sustainable and competitive energy market, it has taken action, amongst other, to support electricity from renewable energy sources (RES-E) and to mitigate CO2 emissions. This paper first qualitatively discusses price- and quantity-based measures for RES-E deployment as well as CO2 mitigation. Next, a simulation model is developed to quantitatively discuss the effects of a tradable green certificate system, a premium mechanism, a tradable CO2 allowance system and a CO2 tax on both RES-E deployment and CO2 mitigation. A three-regional model implementation representing the Benelux, France and Germany is used. In a first step of simulations, all measures are implemented separately. In a second step, combinations of both RES-E supporting and CO2 mitigating measures are simulated and discussed. Significant indirect effects are demonstrated, especially for RES-E supporting measures on the reduction of CO2 emissions. Interactions between different measures show that the price level of quantity-based measures can be strongly influenced.

Optimal synthesis of a pressure swing adsorption process for CO2 capture  

SciTech Connect

The emission of carbon dioxide from cement industry and power plants that burn fossil fuels is the major cause for the accumulation of CO2 in the atmosphere, which causes long-range environmental problems. One option to mitigate the emission of CO2 is to capture it from the emission sources and store it to the ocean or depleted oil field or use it for enhanced oil recovery. CO2 recovery has been achieved by gas absorption employing solutions of carbonates and alkanolamines. However, this process is energy-intensive for the regeneration of solvent and also faces problems due to corrosion. Recently, the pressure swing adsorption (PSA) process has been considered as an alternative to the absorption process. PSA processes have been widely applied for the removal of CO2 from various feed mixtures, such as CO2 in the steam reformer off gas, landfill gas and natural gas. In all these commercial PSA cycles, the weakly adsorbed component in the mixture is the desired product and enriching the strongly adsorbed CO2 is not a concern. On the other hand, for the capture of CO2 for sequestration, it is necessary to concentrate the CO2 to a high purity to reduce the compression and transportation cost. Thus, it is necessary to develop a PSA cycle by which a high-purity product for the strongly adsorbed component with a high recovery is obtained. A multitude of PSA cycles and adsorbents have been developed for producing highly pure heavy component (CO2) from feedstock with low CO2 concentration. Kikkinides et al. suggested a 4-bed 4-step process with activated carbon as the sorbent and could recover 68% of CO2 at 99.997% purity. Chue et al. compared activated carbon and zeolite 13X on a 3-bed 7-step process and concluded that the latter is better than the former for CO2 recovery. However, the CO2 recovery was low in their process due to the lack of a countercurrent step in the chosen cycle. Choi et al. reported more than 70% CO2 recovery at more than 90% purity for a modified 3-bed 7-step cycle. However, they solved a very small two variable optimization problem, thus being a specialized case. Zhang et al. have given justifications for using a specific cyclic component step in the adsorption cycle in the context of CO2 capture by using a simplistic mathematical model for the PSA process. Reynolds et al. have suggested a variety of stripping PSA cycles for CO2 recovery at high temperature using a hydrotalcite-like adsorbent. In this study, a two-bed superstructure of the PSA process has been developed to optimally synthesize an appropriate cycle for CO2 capture. The superstructure considers all the possible operating steps in a PSA cycle with two beds. An optimal control problem with a PDE-based model for PSA system has been formulated in which different steps within a cycle are realized with the help of control variables changing with time. The optimization problem has been solved for three different cases of maximizing CO2 recovery (for a given purity), maximizing feed throughput and minimizing specific power (for a given level of CO2 purity and recovery). Current results indicate the superstructure-based approach as a promising technique for deriving optimal PSA cycles. Different cases with different number of control variables indicate convergence to a particular kind of PSA cycle with over 99% purity and recovery of CO2. The results obtained from optimization problem will also be compared with the optimal PSA cycle simulated more accurately in a dynamic simulation environment.

Geological Sequestration of CO2 by Hydrous Carbonate Formation with Reclaimed Slag  

SciTech Connect

The concept of this project is to develop a process that improves the kinetics of the hydrous carbonate formation reaction enabling steelmakers to directly remove CO2 from their furnace exhaust gas. It is proposed to bring the furnace exhaust stream containing CO2 in contact with reclaimed steelmaking slag in a reactor that has an environment near the unit activity of water resulting in the production of carbonates. The CO2 emissions from the plant would be reduced by the amount sequestered in the formation of carbonates. The main raw materials for the process are furnace exhaust gases and specially prepared slag.

GREENHOUSE GAS EMISSIONS CONTROL BY OXYGEN FIRING IN CIRCULATING FLUIDIZED BED BOILERS: PHASE II--PILOT SCALE TESTING AND UPDATED PERFORMANCE AND ECONOMICS FOR OXYGEN FIRED CFB WITH CO2 CAPTURE  

SciTech Connect

Because fossil fuel fired power plants are among the largest and most concentrated producers of CO{sub 2} emissions, recovery and sequestration of CO{sub 2} from the flue gas of such plants has been identified as one of the primary means for reducing anthropogenic CO{sub 2} emissions. In this Phase II study, ALSTOM Power Inc. (ALSTOM) has investigated one promising near-term coal fired power plant configuration designed to capture CO{sub 2} from effluent gas streams for sequestration. Burning fossil fuels in mixtures of oxygen and recirculated flue gas (made principally of CO{sub 2}) essentially eliminates the presence of atmospheric nitrogen in the flue gas. The resulting flue gas is comprised primarily of CO{sub 2}, along with some moisture, nitrogen, oxygen, and trace gases like SO{sub 2} and NO{sub x}. Oxygen firing in utility scale Pulverized Coal (PC) fired boilers has been shown to be a more economical method for CO{sub 2} capture than amine scrubbing (Bozzuto, et al., 2001). Additionally, oxygen firing in Circulating Fluid Bed Boilers (CFB's) can be more economical than in PC or Stoker firing, because recirculated gas flow can be reduced significantly. Oxygen-fired PC and Stoker units require large quantities of recirculated flue gas to maintain acceptable furnace temperatures. Oxygen-fired CFB units, on the other hand, can accomplish this by additional cooling of recirculated solids. The reduced recirculated gas flow with CFB plants results in significant Boiler Island cost savings resulting from reduced component The overall objective of the Phase II workscope, which is the subject of this report, is to generate a refined technical and economic evaluation of the Oxygen fired CFB case (Case-2 from Phase I) utilizing the information learned from pilot-scale testing of this concept. The objective of the pilot-scale testing was to generate detailed technical data needed to establish advanced CFB design requirements and performance when firing coals and delayed petroleum coke in O{sub 2}/CO{sub 2} mixtures. Firing rates in the pilot test facility ranged from 2.2 to 7.9 MM-Btu/hr. Pilot-scale testing was performed at ALSTOM's Multi-use Test Facility (MTF), located in Windsor, Connecticut.

The effect of CO2 regulations on the cost of corn ethanol production  

Science Journals Connector (OSTI)

To explore the effect of CO2 price on the effective cost of ethanol production we have developed a model that integrates financial and emissions accounting for dry-mill corn ethanol plants. Three policy options are modeled: (1) a charge per unit of life cycle CO2 emissions, (2) a charge per unit of direct biorefinery emissions only, and (3) a low carbon fuel standard (LCFS). A CO2 charge on life cycle emissions increases production costs by between $0.005 and $0.008 l?1 per $10 Mg?1 CO2 price increment, across all modeled plant energy systems, with increases under direct emissions somewhat lower in all cases. In contrast, a LCFS increases the cost of production for selected plant energy systems only: a LCFS requiring reductions in average fuel global warming intensity (GWI) with a target of 10% below the 2005 baseline increases the production costs for coal-fired plants only. For all other plant types, the LCFS operates as a subsidy. The findings depend strongly on the magnitude of a land use change adder. Some land use change adders currently discussed in the literature will push the GWI of all modeled production systems above the LCFS target, flipping the CO2 price from a subsidy to a tax.

Improving the Carbon Dioxide Emission Estimates from the Combustion of Fossil Fuels in California  

SciTech Connect

Central to any study of climate change is the development of an emission inventory that identifies and quantifies the State's primary anthropogenic sources and sinks of greenhouse gas (GHG) emissions. CO2 emissions from fossil fuel combustion accounted for 80 percent of California GHG emissions (CARB, 2007a). Even though these CO2 emissions are well characterized in the existing state inventory, there still exist significant sources of uncertainties regarding their accuracy. This report evaluates the CO2 emissions accounting based on the California Energy Balance database (CALEB) developed by Lawrence Berkeley National Laboratory (LBNL), in terms of what improvements are needed and where uncertainties lie. The estimated uncertainty for total CO2 emissions ranges between -21 and +37 million metric tons (Mt), or -6percent and +11percent of total CO2 emissions. The report also identifies where improvements are needed for the upcoming updates of CALEB. However, it is worth noting that the California Air Resources Board (CARB) GHG inventory did not use CALEB data for all combustion estimates. Therefore the range in uncertainty estimated in this report does not apply to the CARB's GHG inventory. As much as possible, additional data sources used by CARB in the development of its GHG inventory are summarized in this report for consideration in future updates to CALEB.

Techno-economic assessment of CO2 capture at steam methane reforming facilities using commercially available technology  

Science Journals Connector (OSTI)

This study aimed to identify the optimal techno-economic configuration of CO2 capture at steam methane reforming facilities using currently available technologies by means of process simulations. Results indicate that the optimal system is CO2 capture with ADIP-X located between the water–gas shift and pressure swing adsorption units. Process simulations of this system configuration showed a CO2 emission reduction of 60% at 41 €/t CO2 avoidance. This is at the lower end of the range reported in open literature for CO2 capture at refineries (26–82 €/t CO2) and below the avoidance costs for CO2 capture at natural gas-fired power plants (44–93 €/t CO2). CO2 avoidance costs are dominated by the natural gas consumption, responsible for up to 66% of total costs. Using imported steam and electricity can reduce CO2 avoidance costs by 45%. Addition of small amounts of piperazine to aqueous MDEA solutions results in up to 70% smaller absorbers or 10% lower reboiler heat duty. Optimising the whole capture process instead of individual units resulted in lower piperazine concentrations than the common industrial practice (3 mass% vs. 5 mass%). Finally, keeping the solvent rate constant when operating the capture unit below its design load resulted in a lower specific energy for CO2 capture than when the solvent rate was downscaled with the syngas flow.

Evaluation of CO2 enhanced oil recovery and sequestration potential in low permeability reservoirs, Yanchang Oilfield, China  

Science Journals Connector (OSTI)

Abstract Sequestrating CO2 in reservoirs can substantially enhance oil recovery and effectively reduce greenhouse gas emission. To evaluate the potential of CO2 enhanced oil recovery (EOR) and sequestration for Yanchang Oilfield in China, a screening standard which was suitable for CO2-EOR and sequestration in Yanchang Oilfield was proposed based on its characteristics of strong heterogeneity, high water content and severe fluid channeling after water flooding. In addition, an efficient calculation method – stream tube simulation method was presented to figure out CO2 sequestration coefficient and oil recovery factor. After screening and evaluating, it turned out that 148 out of 176 blocks in 22 oilfields were suitable for CO2-EOR and sequestration. CO2 flooding after water flooding can produce 180.21 × 106 t more crude oil and sequestrate 223.38 × 106 t CO2. The average incremental oil recovery rate of miscible reservoirs was 12.49% and the average CO2 sequestration coefficient was 0.27 t/t while the two values were 6.83% and 0.18 t/t for immiscible reservoirs. There are comparatively more reservoirs that are suitable for CO2-EOR and sequestration in Yanchang Oilfield than normal, which can obviously enhance oil recovery and means a great potential for CO2 sequestration. CO2-EOR and sequestration in Yanchang Oilfield has a bright application prospect.

Prevented Mortality and Greenhouse Gas Emissions from Historical and Projected Nuclear Power  

Science Journals Connector (OSTI)

In the aftermath of the March 2011 accident at Japan’s Fukushima Daiichi nuclear power plant, the future contribution of nuclear power to the global energy supply has become somewhat uncertain. ... It seems that, except possibly for Japan, the top five CO2-emitting countries are not planning a phase-down of pre-Fukushima plans for future nuclear power. ... In Japan, the future of nuclear power now seems unclear; in the fiscal year following the Fukushima accident, nuclear power generation in Japan decreased by 63%, while fossil fuel power generation increased by 26% (ref 15), thereby almost certainly increasing Japan’s CO2 emissions. ...

10 MW Supercritical CO2 Turbine Test  

SciTech Connect

The Supercritical CO2 Turbine Test project was to demonstrate the inherent efficiencies of a supercritical carbon dioxide (s-CO2) power turbine and associated turbomachinery under conditions and at a scale relevant to commercial concentrating solar power (CSP) projects, thereby accelerating the commercial deployment of this new power generation technology. The project involved eight partnering organizations: NREL, Sandia National Laboratories, Echogen Power Systems, Abengoa Solar, University of Wisconsin at Madison, Electric Power Research Institute, Barber-Nichols, and the CSP Program of the U.S. Department of Energy. The multi-year project planned to design, fabricate, and validate an s-CO2 power turbine of nominally 10 MWe that is capable of operation at up to 700°C and operates in a dry-cooled test loop. The project plan consisted of three phases: (1) system design and modeling, (2) fabrication, and (3) testing. The major accomplishments of Phase 1 included: Design of a multistage, axial-flow, s-CO2 power turbine; Design modifications to an existing turbocompressor to provide s-CO2 flow for the test system; Updated equipment and installation costs for the turbomachinery and associated support infrastructure; Development of simulation tools for the test loop itself and for more efficient cycle designs that are of greater commercial interest; Simulation of s-CO2 power cycle integration into molten-nitrate-salt CSP systems indicating a cost benefit of up to 8% in levelized cost of energy; Identification of recuperator cost as a key economic parameter; Corrosion data for multiple alloys at temperatures up to 650ºC in high-pressure CO2 and recommendations for materials-of-construction; and Revised test plan and preliminary operating conditions based on the ongoing tests of related equipment. Phase 1 established that the cost of the facility needed to test the power turbine at its full power and temperature would exceed the planned funding for Phases 2 and 3. Late in Phase 1 an opportunity arose to collaborate with another turbine-development team to construct a shared s-CO2 test facility. The synergy of the combined effort would result in greater facility capabilities than either separate project could produce and would allow for testing of both turbine designs within the combined budgets of the two projects. The project team requested a no-cost extension to Phase 1 to modify the subsequent work based on this collaborative approach. DOE authorized a brief extension, but ultimately opted not to pursue the collaborative facility and terminated the project.

Capture and Sequestration of CO2 at the Boise White Paper Mill  

SciTech Connect

This report documents the efforts taken to develop a preliminary design for the first commercial-scale CO2 capture and sequestration (CCS) project associated with biomass power integrated into a pulp and paper operation. The Boise Wallula paper mill is located near the township of Wallula in Southeastern Washington State. Infrastructure at the paper mill will be upgraded such that current steam needs and a significant portion of the current mill electric power are supplied from a 100% biomass power source. A new biomass power system will be constructed with an integrated amine-based CO2 capture plant to capture approximately 550,000 tons of CO2 per year for geologic sequestration. A customized version of Fluor Corporation’s Econamine Plus™ carbon capture technology will be designed to accommodate the specific chemical composition of exhaust gases from the biomass boiler. Due to the use of biomass for fuel, employing CCS technology represents a unique opportunity to generate a net negative carbon emissions footprint, which on an equivalent emissions reduction basis is 1.8X greater than from equivalent fossil fuel sources (SPATH and MANN, 2004). Furthermore, the proposed project will offset a significant amount of current natural gas use at the mill, equating to an additional 200,000 tons of avoided CO2 emissions. Hence, the total net emissions avoided through this project equates to 1,100,000 tons of CO2 per year. Successful execution of this project will provide a clear path forward for similar kinds of emissions reduction that can be replicated at other energy-intensive industrial facilities where the geology is suitable for sequestration. This project also represents a first opportunity for commercial development of geologic storage of CO2 in deep flood basalt formations. The Boise paper mill site is host to a Phase II pilot study being carried out under DOE’s Regional Carbon Partnership Program. Lessons learned from this pilot study and other separately funded projects studying CO2 sequestration in basalts will be heavily leveraged in developing a suitable site characterization program and system design for permanent sequestration of captured CO2. The areal extent, very large thickness, high permeability in portions of the flows, and presence of multiple very low permeability flow interior seals combine to produce a robust sequestration target. Moreover, basalt formations are quite reactive with water-rich supercritical CO2 and formation water that contains dissolved CO2 to generate carbonate minerals, providing for long-term assurance of permanent sequestration. Sub-basalt sediments also exist at the site providing alternative or supplemental storage capacity.

NLE Websites -- All DOE Office Websites (Extended Search)

CO CO 2 Sequestration in a Saline Reservoir and Depleted Oil Reservoir to Evaluate The Regional CO 2 Sequestration Potential of The Ozark Plateau Aquifer System, South-Central Kansas Background Carbon capture, utilization and storage (CCUS) technologies offer the potential for reducing CO 2 emissions without adversely influencing energy use or hindering economic growth. Deploying these technologies in commercial-scale applications requires adequate geologic formations capable of (1) storing large volumes of CO 2 , (2) receiving injected CO 2 at efficient and economic rates, and (3) retaining CO 2 safely over extended periods. Research efforts are currently focused on conventional and unconventional storage formations within depositional environments such as: deltaic, fluvial, alluvial,

Electricity generation from coal with CO2 capture by means of a novel power cycle  

SciTech Connect

Climate modelers have estimated that anthropogenic emissions of CO2 must be reduced substantially from the present rate to stabilize atmospheric concentration. To achieve this, electricity generation from fossil fuels with CO2 capture and direct sequestration may play an important role. If so, it will be worthwhile to consider power cycles that are designed to minimize atmospheric CO2 emissions and deliver CO2 ready for pipeline transport in addition to providing other desirable attributes of environmental performance and efficiency. One such novel approach, named the Matiant cycle, employs self generated CO2 as the working fluid with both Bryton and Rankine cycle turbines. Process modeling studies are being conducted at the NETL to investigate the promise of this cycle. In the work to be reported, synthesis gas is provided to the Matiant cycle by oxygen-blown dry coal entrained gasification. Oxygen for both the gasifier and the Matiant cycle is provided by use of an Ion Transport Membrane (ITM). ITM is a revolutionary approach for producing high purity oxygen from a high temperature pressurized air stream. ASPEC Plus is used as the simulation tool to compute energy balances and system performance. Two flowsheets are analyzed, the difference being the treatment of the low oxygen content raffinate stream from the ITM. Computed thermal efficiencies of the ITM/Matiant cycle are comparable to those of conventional IGCC without carbon capture. Specific carbon emissions per net MWh are many times lower for the new cycle than for other approaches being developed for power generation with CO2 capture, however. As much as 99.5% of the carbon in synthesis gas fed to the Matiant cycle could be recovered and removed in a pipeline as a high pressure liquid. Such high capture efficiencies at large central generating stations could allow use of fossil fuels without capture at smaller installations or by mobile sources, yielding a modest overall rate of CO2 emissions.
