Photovoltaic Small-Scale Wastewater Treatment Project for Rural and New-Cultivated Areas in  

E-Print Network (OSTI)

Abstract—The problem of wastewater treatment in Egypt is a two-fold problem; the first part concerning the existing rural areas, the second one dealing with new industrial/domestic areas. In Egypt several agricultural projects have been initiated by the government and the private sector as well, in order to change its infrastructure. As a reliable energy source, photovoltaic pumping systems have contributed to supply water for local rural communities worldwide; they can also be implemented to solve the problem “wastewater environment pollution”. The solution of this problem can be categorised as recycle process. In addition, because of regional conditions past technologies are being reexamined to select a smallscale treatment system requiring low construction and maintenance costs. This paper gives the design guidelines of a Photovoltaic Small-Scale Wastewater Treatment Plant (PVSSWTP) based on technologies that can be transferred. Keywords—Renewable energy sources, Photovoltaic, small-scale projects, wastewater treatment. I.

Investigating the option of installing small scale \\{PVs\\} on facility rooftops in a green supply chain  

Science Journals Connector (OSTI)

Abstract Industry practitioners and policy makers are under increasing pressure to promote green supply chains through the integration of renewable energy sources. Changing facilities from net energy users to net energy producers is a major concern for supply chain managers who are interested in greening their business. Building integrated photovoltaics (BIPV) is an innovative design idea to achieve energy positive buildings. In a BIPV building, photovoltaic (PV) arrays are integrated into the structure of the building in order to transform the incident solar radiation to clean energy that can be used in facility operations. This option is dependent on the economic attractiveness of the solar PVs, which, in return, depends on the policies (incentives, subsidies, feed-in tariff) in effect at the facility location, the efficiency of the \\{PVs\\} installed, and the amount of incident solar radiation at the facility location. We present an economic model that calculates the cost per kWh capacity of solar \\{PVs\\} installed and then integrate the decision of installing \\{PVs\\} of different sizes on the facility rooftops of a supply chain subject to the different environmental policies available. We study the implications of our model based on a sensitivity analysis for different carbon credit prices, PV generation costs, and feed-in tariff prices.

Economic evaluation of small-scale photovoltaic hybrid systems for mini-grid applications in far north Cameroon  

Science Journals Connector (OSTI)

A comparison between photovoltaic hybrid systems (PVHS), standalone photovoltaic (PV) and standalone diesel generator options is performed using the net present value (NPV) technique. A typical village mini-grid energy demand of 7.08 kWh/day is considered in the computation of energy costs and breakeven grid distances. A first sensitivity analysis is conducted using remote diesel prices of 0.8 €/l, 0.98 €/l, 1.12 €/l, 1.28 €/l with a PV module cost of 7.5 €/Wp. A second sensitivity analysis is also done using PV module costs of 5.25 €/Wp, 6 €/Wp, 6.75 €/Wp, 7.5 €/Wp with a diesel price of 1.12 €/l. The energy cost for the diesel option was found to be 0.812 €/kWh at a diesel fuel price of 1.12 €/l. The sensitivity analyses showed that minimum energy costs were attained in PVHS at renewable energy fractions in the range 82.6–95.3%. In the second sensitivity analysis the energy costs and breakeven grid distances were found to be in the ranges 0.692–0.785 €/kWh and 5.1–5.9 km respectively. For a PV module cost of 5.25 €/Wp, the lowest energy cost for the PVHS option was 0.692 €/kWh at a final renewable energy fraction of 95.3% with the diesel generator hours being 37 h compared to 2075 h in the standalone diesel generator option. Consequently, a 30% reduction in custom duties and taxes on imported PV modules and sub-systems would increase the use of small-scale and climate friendly PV mini-grids in remote areas of far north Cameroon that have an annual insolation of at least 5.55 kWh/m2/day.

Maximizing the Value of Photovoltaic Installations on Schools in California: Choosing the Best Electricity Rates  

SciTech Connect

Schools in California often have a choice between multiple electricity rate options. For schools with photovoltaic (PV) installations, choosing the right rate is essential to maximize the value of PV generation. The rate option that minimizes a school?s electricity expenses often does not remain the most economical choice after the school installs a PV system. The complex interaction between PV generation, building load, and rate structure makes determining the best rate a challenging task. This report evaluates 22 rate structures across three of California?s largest electric utilities--Pacific Gas and Electric Co. (PG&E), Southern California Edison (SCE), and San Diego Gas and Electric (SDG&E)--in order to identify common rate structure attributes that are favorable to PV installations.

Tracking the Sun VII: An Historical Summary of the Installed Price of Photovoltaics in the United States from 1998 to 2013  

SciTech Connect

As the deployment of grid-connected solar photovoltaic (PV) systems has increased, so too has the desire to track the cost and price of these systems. This report helps to fill this need by summarizing trends in the installed price of grid-connected PV systems in the United States from 1998 through 2013, with partial data for the first half of 2014. The analysis is based on project-level data for more than 300,000 individual residential, commercial, and utility-scale PV systems installed across 33 states and representing 80% of all grid-connected PV capacity installed in the United States through 2013. It is essential to note at the outset what the data presented within this report represent. First, the data consist of prices paid to project developers or installers (prior to receipt of any incentives), and for a variety of reasons, those prices may differ from the underlying costs borne by project developers/installers. Second, the data are historical, focusing primarily on projects installed through the end of 2013, and therefore do not reflect the price of projects installed more recently (with the exception of the limited set of results presented for systems installed in the first half of 2014); nor are the data indicative of prices currently being quoted for prospective projects to be installed at a later date. For these reasons and others, the results presented in this report may differ from current PV price or cost benchmarks. Third, by focusing on the up-front price paid by the PV system owner prior, the report does not capture trends associated with PV performance or other factors that impact the levelized cost of electricity for PV. Finally, the underlying data collected for this report include third party owned (TPO) projects where either the system is leased to the site-host or the generation output is sold to the site-host under a power purchase agreement. For a subset of TPO systems, the installed price data represent appraised values rather than transaction prices, and those projects were removed from the data sample in order to eliminate any associated bias. The report presents one set of installed price trends for residential and commercial PV systems, and another set for utility-scale PV. In all cases, installed prices are identified in terms of real 2013 dollars per installed watt (DC-STC), prior to receipt of any direct financial incentives or tax credits. This report separately summarizes installed price data for utility-scale PV projects, drawing upon data also presented in LBNL’s companion report, Utility Scale Solar 2013: An Empirical Analysis of Project Cost, Performance, and Pricing Trends in the United States. For our purposes, utility-scale PV is defined to consist of ground-mounted projects larger than 5 MW. The sample of installed price data includes 97 projects with commercial operation dates spanning the period 2007- 2013. Several important features of the utility-scale data are worth noting, in addition to those noted earlier for the dataset as a whole. First, the sample includes only fully operational projects for which all individual phases are in operation and treats all phases as a single project with a commercial operation date based on the final phase. Second, installed prices reported for utility-scale projects often reflect transactions that occurred several years before project completion; the prices reported for some of these projects may not fully capture recent reductions in module costs or other changes in market conditions, and thus may exhibit a relatively large “temporal lag”.

Hoopa Valley Small Scale Hydroelectric Feasibility Project  

SciTech Connect

This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California (http://www.hoopa-nsn.gov/). This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

Electric grid dependence on the configuration of a small-scale wind and solar power hybrid system  

Science Journals Connector (OSTI)

Results are presented from the modeling of a small-scale distributed power system containing power demands, photovoltaic arrays, small-scale wind turbines and an electric grid connection. Detailed models of the photovoltaic array and the wind turbine are briefly explained in addition to the solar and wind recourse models. A subunit is defined to consist of a power demand together with power contributors. It is shown how the grid dependency (or renewable energy contribution) is affected by the connection of subunits and according to the relationship between the power demand patterns and renewable resource patterns. The outcome from several case studies is presented using simulated power demands and renewable resources. In a scenario with subunit power demands characteristic for a large household and a small factory, it is shown that the coupling of subunits reduces annual grid power transfers by more than 10% and increases the renewable power contribution to the demand by almost 7%.

Integrating Small Scale Distributed Generation into a Deregulated Market: Control Strategies and Price Feedback  

E-Print Network (OSTI)

Small scale power generating technologies, such as gas turbines, small hydro turbines, photovoltaics, wind turbines and fuel cells, are gradually replacing conventional generating technologies, for various applications, in the electric power system. The industry restructuring process in the United States is exposing the power sector to market forces, which is creating competitive structures for generation and alternative regulatory structures for the transmission and distribution systems. The potentially conflicting economic and technical demands of the new, independent generators introduce a set of significant uncertainties. What balance between market forces and centralized control will be found to coordinate distribution system operations? How will the siting of numerous small scale generators in distribution feeders impact the technical operations and control of the distribution system? Who will provide ancillary services (such as voltage support and spinning reserves) in the new competitive environment? This project investigates both the engineering and market integration of distributed generators into the distribution system. On the technical side, this project investigates the frequency performance of a distribution system that has multiple small scale generators. Using IEEE sample distribution systems and new dynamic generator models, this project develops general methods for

The solar photovoltaic feed-in tariff scheme in New South Wales, Australia  

Science Journals Connector (OSTI)

Abstract Solar Photovoltaic (PV) electricity systems are part of Australia's energy supply matrix. In the case of New South Wales (NSW), the state government has had to deal with a complex policy problem. In order to play its role in the federal Small-scale Renewable Energy Scheme, the NSW government initiated the 7 year Solar Bonus Scheme in 2010. However, in attempting to maximise community investment in small-scale solar PV systems, it relied on faulty financial modelling that applied a generous Feed-in Tariff (FiT) and underestimated the level of investor participation and installed capacity. Consequently, the scheme has resulted in very high public costs that will require policy changes that bring investors and energy retailers into conflict, and unpopular electricity retail price adjustments. This paper uses a structured case and stakeholder analysis to critically analyse the FiT policy, while also highlighting important lessons for policymakers engaging in FiT design.

NETL: Carbon Storage - Small-Scale Field Tests  

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

Small-Scale Field Tests Small-Scale Field Tests Carbon Storage Small-Scale Field Tests The U.S. Department of Energy (DOE) is supporting a number of small-scale field tests (injection of less than 500,000 million metric tons of CO2 per year) to explore various geologic CO2 storage opportunities within the United States and portions of Canada. DOE's small-scale field test efforts are designed to demonstrate that regional reservoirs have the capability to store thousands of years of CO2 emissions and provide the basis for larger volume, commercial-scale CO2 tests. The field studies are focused on developing better understanding 11 major types of geologic storage reservoir classes, each having their own unique opportunities and challenges. Understanding these different storage classes provides insight into how the systems influence fluids flow within these systems today, and how CO2 in geologic storage would be anticipated to flow in the future. The different storage formation classes include: deltaic, coal/shale, fluvial, alluvial, strandplain, turbidite, eolian, lacustrine, clastic shelf, carbonate shallow shelf, and reef. Basaltic interflow zones are also being considered as potential reservoirs. These storage reservoirs contain fluids that may include natural gas, oil, or saline water; any of which may impact CO2 storage differently. The data gathered during these small-scale tests provides valuable information regarding specific formations that have historically not been evaluated for the purpose of CO2 storage. The Carbon Storage Program strategy includes an established set of field test objectives applicable to the small-scale projects:

Streamers generation by small-scale drift-Alfvén waves  

SciTech Connect

Excitation of streamers by modulationally unstable small-scale drift-Alfvén wave (SSDAW) is investigated. It is found that the excitation depends strongly on the propagation direction of the SSDAW, and the ion and electron diamagnetic drift waves are both unstable due to the generation of streamers. It is also shown that zonal flows can be effectively excited by the SSDAW with the propagation direction different from that for streamer excitation.

ABSTRACT From an economic perspective, small-scale geothermal heating systems and ground water source heat pump schemes can be assessed using similar approaches. In particular, assessment shows that heat pump schemes can be economic in the U.K., especially for buildings with moderately high and continuous heating demand, with access to shallow, free-flowing ground water, in areas where prices for conventional fuels are high.

Small Scale Coal Biomass Liquids Production Using Highly Selective Fischer  

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

Small Scale Coal Biomass Liquids Production Using Highly Selective Fischer Tropsch Catalyst Small Scale Coal Biomass Liquids Production Using Highly Selective Fischer Tropsch Catalyst Southern Research Institute Project Number: FE0010231 Project Description Fischer-Tropsch (FT) process converts a mixture of carbon monoxide and hydrogen, called syngas, into liquid hydrocarbons. It is a leading technology for converting syngas derived from gasification of coal and coal-biomass mixtures to hydrocarbons in coal to liquids (CTL) and coal-biomass to liquids (CBTL) processes. However, conventional FTS catalysts produce undesirable waxes (C21+) that need to be upgraded to liquids (C5-C20) by hydrotreating. This adds significantly to the cost of FTS. The objectives of this project are (i) to demonstrate potential for CBTL cost reduction by maximizing the production of C5-C20 hydrocarbon liquids using a selective FTS catalyst and (ii) to evaluate the impacts of the addition of biomass to coal on product characteristics, carbon foot print, and economics.

Preliminary Scaling Estimate for Select Small Scale Mixing Demonstration Tests  

SciTech Connect

The Hanford Site double-shell tank (DST) system provides the staging location for waste that will be transferred to the Hanford Tank Waste Treatment and Immobilization Plant (WTP). Specific WTP acceptance criteria for waste feed delivery describe the physical and chemical characteristics of the waste that must be met before the waste is transferred from the DSTs to the WTP. One of the more challenging requirements relates to the sampling and characterization of the undissolved solids (UDS) in a waste feed DST because the waste contains solid particles that settle and their concentration and relative proportion can change during the transfer of the waste in individual batches. A key uncertainty in the waste feed delivery system is the potential variation in UDS transferred in individual batches in comparison to an initial sample used for evaluating the acceptance criteria. To address this uncertainty, a number of small-scale mixing tests have been conducted as part of Washington River Protection Solutions’ Small Scale Mixing Demonstration (SSMD) project to determine the performance of the DST mixing and sampling systems.

Preliminary experimental analysis of a small-scale prototype SWRO desalination plant, designed for continuous adjustment of its energy consumption to the widely varying power generated by a stand-alone wind turbine  

Science Journals Connector (OSTI)

Abstract Given the significant water-energy problems associated with many remote and arid areas of the planet, most studies, projects and developments of installations for the production of fresh water using desalination technologies powered by renewable energy sources have focussed on small-scale stand-alone systems. The most commonly used energy sources have been solar photovoltaic and wind and the most widely applied desalination technology that of reverse osmosis (RO). Most of the systems use batteries as a means of mass energy storage and the RO plants normally operate at constant pressure and flow rate. This paper presents a small-scale prototype SWRO (seawater reverse osmosis) desalination plant designed to continuously adapt its energy consumption to the variable power supplied by a wind turbine (WT), dispensing with mass energy storage in batteries and proposing the use of a supercapacitor bank as a dynamic regulation system. A description is given of the tests performed to date with the SWRO desalination plant connected to the conventional grid while controlling the number of pressure vessels that are connected/disconnected to/from the system and regulating their operating pressures and flow rates (within predetermined admissible limits) to maintain a constant permeate recovery rate and adapt the energy consumption of the plant to a widely varying simulated wind energy supply. One of the most important conclusions that can be drawn from the studies undertaken is the feasibility of adapting the consumption of the prototype of the SWRO desalination plant to widely varying WT-generated power. Despite using various time interval lengths in which it was assumed that the WT output power remained constant, a perfect fit was not obtained between the theoretical WT-generated power and the power consumed by the SWRO desalination plant, nor was it possible to maintain a constant permeate recovery rate at each instant.

Low-cost small scale processing technologies for production applications in various environments—Mass produced factories  

Science Journals Connector (OSTI)

The requirements for chemical and food production technologies will change in the future as a result of shorter time to market and increasing market volatility. Especially the rising use of renewable resources will require the implementation of flexible and fast to install small-scale production technologies. The increasing number of necessary apparatuses and their distributed operation, however, will constitute major challenges, both economically and procedurally. The proposed solution to face the economic challenge is modularization and standardization. For food production, dewatering represents a key issue. Thus, biomass processing should first be divided into small-scale water separation steps and then into further large-scale processing steps. As dewatering usually happens thermally and heat exchangers often benefit from the economies of scale, heat supply and energy consumption or heat transfer with little capital investment are further issues. Therefore, temperature levels should be decreased and the use of solar heat increased. For the production of biofuels and chemicals from biomass, process integration and process simplification are proposed to improve the efficacy of production equipment and processes. Choosing raw materials with molecular structures, similar to the desired chemical building block, will lower the need for heat exchange and make small-scale manufacturing of fuels and chemicals possible.

Small Scale Clustering of Late Forming Dark Matter  

E-Print Network (OSTI)

We perform a study of the non-linear clustering of matter in the Late Forming Dark Matter (LFDM) scenario in which dark matter results from the transition of non-minimally coupled scalar field from radiation to collisionless matter. A distinct feature of this model is the presence of a damped oscillatory cut-off in the linear matter power spectrum at small scales. We use a suite of high-resolution N-body simulations to study the imprints of LFDM on the non-linear matter power spectrum, the halo mass function and the halo density profiles. The model satisfies high-redshift matter power spectrum constraints from Lyman-$\\alpha$ forest measurements. We find suppressed abundance of low mass halos ($\\sim 10^{9}-10^{10}$ h$^{-1}$ M$_\\odot$) at all redshifts compared to a vanilla $\\Lambda$CDM model. Furthermore, in this mass range we find significant deviations with respect to predictions from the Sheth-Tormen mass function. Halos with mass $M\\gtrsim 10^{11}$ h$^{-1}$ M$_\\odot$ show minor departures of the density pr...

Developments in a small scale test of violence  

Science Journals Connector (OSTI)

Utilising recent advances in diagnostic technologies a test is under development to obtain a numerical value for the violence of response to thermal stimuli on a small explosive sample. The assembly is designed to accept pressed explosive pellets which enables the test to be conducted at the small-scale development stage and thus is anticipated to be of use in the screening of new materials. Building on previously published work describing the test development twenty-three new cook-off experiments have been conducted. Eleven explosive compositions were subjected to the same slow heat input profile. As a sample rapidly decomposed part of the steel confinement was designed to rupture producing a pellet whose velocity was measured using a Heterodyne Velocimeter (Het-V). Temperatures of the confinement unit were also recorded. A development aim is to interpret this data to provide useful information on the violence of decomposition. This is discussed in the paper and leads to the data from these experiments being presented in order of increasing violence of response.

ARCADE small-scale docking mechanism for micro-satellites  

Science Journals Connector (OSTI)

The development of on-orbit autonomous rendezvous and docking (ARD) capabilities represents a key point for a number of appealing mission scenarios that include activities of on-orbit servicing, automated assembly of modular structures and active debris removal. As of today, especially in the field of micro-satellites ARD, many fundamental technologies are still missing or require further developments and micro-gravity testing. In this framework, the University of Padova, Centre of Studies and Activities for Space (CISAS), developed the Autonomous Rendezvous Control and Docking Experiment (ARCADE), a technology demonstrator intended to fly aboard a BEXUS stratospheric balloon. The goal was to design, build and test, in critical environment conditions, a proximity relative navigation system, a custom-made reaction wheel and a small-size docking mechanism. The ARCADE docking mechanism was designed against a comprehensive set of requirements and it can be classified as small-scale, central, gender mating and unpressurized. The large use of commercial components makes it low-cost and simple to be manufactured. Last, it features a good tolerance to off-nominal docking conditions and a by-design soft docking capability. The final design was extensively verified to be compliant with its requirements by means of numerical simulations and physical testing. In detail, the dynamic behaviour of the mechanism in both nominal and off-nominal conditions was assessed with the multibody dynamics analysis software MD ADAMS 2010 and functional tests were carried out within the fully integrated ARCADE experiment to ensure the docking system efficacy and to highlight possible issues. The most relevant results of the study will be presented and discussed in conclusion to this paper.

The feed-in tariff in the UK: A case study focus on domestic photovoltaic systems  

Science Journals Connector (OSTI)

This paper explores the photovoltaic (PV) industry in the United Kingdom (UK) as experienced by those who are working with it directly and with consideration of current standards, module efficiencies and future environmental trends. The government's consultation on the comprehensive review for solar PV tariffs, proposes a reduction of the generation tariff for PV installations in the UK of more than 50%. The introduction of the Feed-In Tariffs scheme (FITs) has rapidly increased deployment of PV technologies at small scale since its introduction in April 2010. The central principle of FIT policies is to offer guaranteed prices for fixed periods to enable greater number of investors. A financial analysis was performed on two real-life installations in Cornwall, UK to determine the impact of proposed cuts to the FIT will make to a typical domestic PV system under 4 kW. The results show that a healthy Return on Investment (ROI) can still be made but that future installations should focus on off-setting electricity required from the national grid as a long term push for true sustainability rather than subsidised schemes. The profitability of future installations will have to be featured within in-service and end-of-service considerations such as the feed-in tariff, module efficiencies and the implications of costs associated with end-of-life disposal.

THE EXTREME SMALL SCALES: DO SATELLITE GALAXIES TRACE DARK MATTER?  

SciTech Connect

We investigate the radial distribution of galaxies within their host dark matter halos as measured in the Sloan Digital Sky Survey by modeling their small-scale clustering. Specifically, we model the Jiang et al. measurements of the galaxy two-point correlation function down to very small projected separations (10 h{sup -1} kpc {<=} r {<=} 400 h{sup -1} kpc), in a wide range of luminosity threshold samples (absolute r-band magnitudes of -18 up to -23). We use a halo occupation distribution framework with free parameters that specify both the number and spatial distribution of galaxies within their host dark matter halos. We assume one galaxy resides in the halo center and additional galaxies are considered satellites that follow a radial density profile similar to the dark matter Navarro-Frenk-White (NFW) profile, except that the concentration and inner slope are allowed to vary. We find that in low luminosity samples (M{sub r} < -19.5 and lower), satellite galaxies have radial profiles that are consistent with NFW. M{sub r} < -20 and brighter satellite galaxies have radial profiles with significantly steeper inner slopes than NFW (we find inner logarithmic slopes ranging from -1.6 to -2.1, as opposed to -1 for NFW). We define a useful metric of concentration, M{sub 1/10}, which is the fraction of satellite galaxies (or mass) that are enclosed within one-tenth of the virial radius of a halo. We find that M{sub 1/10} for low-luminosity satellite galaxies agrees with NFW, whereas for luminous galaxies it is 2.5-4 times higher, demonstrating that these galaxies are substantially more centrally concentrated within their dark matter halos than the dark matter itself. Our results therefore suggest that the processes that govern the spatial distribution of galaxies, once they have merged into larger halos, must be luminosity dependent, such that luminous galaxies become poor tracers of the underlying dark matter.

Small-Scale Spray Releases: Initial Aerosol Test Results  

SciTech Connect

One of the events postulated in the hazard analysis at the Waste Treatment and Immobilization Plant (WTP) and other U.S. Department of Energy (DOE) nuclear facilities is a breach in process piping that produces aerosols with droplet sizes in the respirable range. The current approach for predicting the size and concentration of aerosols produced in a spray leak involves extrapolating from correlations reported in the literature. These correlations are based on results obtained from small engineered spray nozzles using pure liquids with Newtonian fluid behavior. The narrow ranges of physical properties on which the correlations are based do not cover the wide range of slurries and viscous materials that will be processed in the WTP and across processing facilities in the DOE complex. Two key technical areas were identified where testing results were needed to improve the technical basis by reducing the uncertainty due to extrapolating existing literature results. The first technical need was to quantify the role of slurry particles in small breaches where the slurry particles may plug and result in substantially reduced, or even negligible, respirable fraction formed by high-pressure sprays. The second technical need was to determine the aerosol droplet size distribution and volume from prototypic breaches and fluids, specifically including sprays from larger breaches with slurries where data from the literature are scarce. To address these technical areas, small- and large-scale test stands were constructed and operated with simulants to determine aerosol release fractions and generation rates from a range of breach sizes and geometries. The properties of the simulants represented the range of properties expected in the WTP process streams and included water, sodium salt solutions, slurries containing boehmite or gibbsite, and a hazardous chemical simulant. The effect of anti-foam agents was assessed with most of the simulants. Orifices included round holes and rectangular slots. The round holes ranged in size from 0.2 to 4.46 mm. The slots ranged from (width × length) 0.3 × 5 to 2.74 × 76.2 mm. Most slots were oriented longitudinally along the pipe, but some were oriented circumferentially. In addition, a limited number of multi-hole test pieces were tested in an attempt to assess the impact of a more complex breach. Much of the testing was conducted at pressures of 200 and 380 psi, but some tests were conducted at 100 psi. Testing the largest postulated breaches was deemed impractical because of the large size of some of the WTP equipment. This report presents the experimental results and analyses for the aerosol measurements obtained in the small-scale test stand. It includes a description of the simulants used and their properties, equipment and operations, data analysis methodologies, and test results. The results of tests investigating the role of slurry particles in plugging small breaches are reported in Mahoney et al. (2012). The results of the aerosol measurements in the large-scale test stand are reported in Schonewill et al. (2012) along with an analysis of the combined results from both test scales.

Two key technical areas were identified where testing results were needed to improve the technical basis by reducing the uncertainty due to extrapolating existing literature results. The first technical need was to quantify the role of slurry particles in small breaches where the slurry particles may plug and result in substantially reduced, or even negligible, respirable fraction formed by high-pressure sprays. The second technical need was to determine the aerosol droplet size distribution and volume from prototypic breaches and fluids, specifically including sprays from larger breaches with slurries where data from the literature are scarce. To address these technical areas, small- and large-scale test stands were constructed and operated with simulants to determine aerosol release fractions and net generation rates from a range of breach sizes and geometries. The properties of the simulants represented the range of properties expected in the WTP process streams and included water, sodium salt solutions, slurries containing boehmite or gibbsite, and a hazardous chemical simulant. The effect of antifoam agents was assessed with most of the simulants. Orifices included round holes and rectangular slots. For the combination of both test stands, the round holes ranged in size from 0.2 to 4.46 mm. The slots ranged from (width × length) 0.3 × 5 to 2.74 × 76.2 mm. Most slots were oriented longitudinally along the pipe, but some were oriented circumferentially. In addition, a limited number of multi-hole test pieces were tested in an attempt to assess the impact of a more complex breach. Much of the testing was conducted at pressures of 200 and 380 psi, but some tests were conducted at 100 psi. Testing the largest postulated breaches was deemed impractical because of the much larger flow rates and equipment that would be required. This report presents the experimental results and analyses for the aerosol measurements obtained in the small-scale test stand. It includes a description of the simulants used and their properties, equipment and operations, data analysis methodologies, and test results. The results of tests investigating the role of slurry particles in plugging small breaches are reported in Mahoney et al. (2012). The results of the aerosol measurements in the large-scale test stand are reported in Schonewill et al. (2012) along with an analysis of the combined results from both test scales.

Residential photovoltaic systems costs  

SciTech Connect

A study of costs associated with the installation and operation of a residential photovoltaic system has been conducted to determine present and projected (1986) status. As a basis for the study, a residential photovoltaic system design projected for 1986 was assumed, consisting of two principal components: a roof-mounted array and a utility-interactive inverter. The scope of the study encompassed both silicon and cadmium sulfide photovoltaic modules. Cost estimates were obtained by a survey and study of reports generated by companies and agencies presently active in each of the subsystem area. Where necessary, supplemental estimates were established as part of this study. The range of estimates for silicon-based systems strongly suggest that such systems will be competitive for new installations and reasonably competitive for retrofit applications. The cadmium-sulfide-based system cost estimates, which are less certain than those for silicon, indicate that these systems will be marginally competitive with silicon-based systems for new construction, but not competitive for retrofit applications. Significant variations from the DOE system price sub-goals were found, however, particularly in the areas of array mounting, wiring and cleaning. Additional development work appears needed in these areas.

Cosmic string cusps with small-scale structure: Their forms and gravitational waveforms  

Science Journals Connector (OSTI)

We present a method for the introduction of small-scale structure into strings constructed from products of rotation matrices. We use this method to illustrate a range of possibilities for the shape of cusps that depends on the properties of the small-scale structure. We further argue that the presence of structure at cusps under most circumstances leads to the formation of loops at the size of the smallest scales. On the other hand we show that the gravitational waveform of a cusp remains generally unchanged; the primary effect of small-scale structure is to smooth out the sharp waveform emitted in the direction of cusp motion.

A study of small-scale energy networks of the Japanese Syowa Base in Antarctica by distributed engine generators  

Science Journals Connector (OSTI)

Abstract Fuel traffic to the Syowa Base of the South Pole is increasing from Japan, with growing research and observation occurring every year. Limits to fuel traffic and the spread of green energy utilization are topics of interest for Syowa Base; this research considers the construction of a Syowa Base small-scale energy network (Syowa Base Micro-Grid: SBMG) for the purposes of reducing fuel consumption and increasing green energy utilization. The number of engine generators, the operation plan for the battery’s charge and discharge, and the introduction of an exhaust heat pump provided a means by which the load factor of the engine generator could be maintained high value from the fluctuations of green energy. This might be accomplished by modifying the main power supply of Syowa Base into a distributed power supply system rather than a conventional central power supply system. The relationship between the amount of green energy (photovoltaics and wind power generation) connected to the proposed power supply distribution and the amount of fuel consumed by the engine generators and backup boiler was clarified. Moreover, the outside temperatures, insulation levels, and wind velocity at the Syowa Base change seasonally, resulting in large changes in the SBMG operation method. Therefore, differences in the operation methods between the proposed power supply distribution system and the conventional central power supply were assessed during the summer (January), winter (July), and mid-season (October), and the resulting differences in fuel consumption were clarified.

Photovoltaic waste assessment in Italy  

Science Journals Connector (OSTI)

Abstract At present, photovoltaics is, after hydro and wind power, the third most important renewable energy source in terms of its capacity to be globally installed; furthermore, for two years in a row, it was the number one new source of electricity generation installed in the European Union. Italy became the second country in the European Union concerning the cumulative installed power of PV (in 2013, the Italian PV cumulative power reached over 17,620 MW), which was also the result of the very attractive support policy. In connection with this development, the issue has emerged about the treatment and disposal of photovoltaic waste when the operative time (approximately twenty-thirty years) of the photovoltaic systems ended. The European Union, to address this environmental impact, passed the Directive 2012/19/EU to increase the amount of waste of electrical and electronic equipment in the form of photovoltaic panels that have been appropriately collected and treated to reduce the volume that become disposed. This paper aims to provide an assessment of the potential waste arising in Italy from the use and end-of-life phases of these renewable energy systems in the coming years and their disposal and/or recycling. Based on the lifetime of 25 years of photovoltaic panels, the estimate has been referred to two periods of waste generation (2012–2038 and 2039–2050). The importance of managing this flow of waste to enhance the correct disposal of the hazardous substances as well as the importance of the recovery and recycling of valuable resources has also been underlined.

Nanostructured photovoltaics  

Science Journals Connector (OSTI)

Energy and the environment are two of the most important global issues that we currently face. The development of clean and sustainable energy resources is essential to reduce greenhouse gas emission and meet our ever-increasing demand for energy. Over the last decade photovoltaics, as one of the leading technologies to meet these challenges, has seen a continuous increase in research, development and investment. Meanwhile, nanotechnology, which is considered to be the technology of the future, is gradually revolutionizing our everyday life through adaptation and incorporation into many traditional technologies, particularly energy-related technologies, such as photovoltaics. While the record for the highest efficiency is firmly held by multijunction III–V solar cells, there has never been a shortage of new research effort put into improving the efficiencies of all types of solar cells and making them more cost effective. In particular, there have been extensive and exciting developments in employing nanostructures; features with different low dimensionalities, such as quantum wells, nanowires, nanotubes, nanoparticles and quantum dots, have been incorporated into existing photovoltaic technologies to enhance their performance and/or reduce their cost. Investigations into light trapping using plasmonic nanostructures to effectively increase light absorption in various solar cells are also being rigorously pursued. In addition, nanotechnology provides researchers with great opportunities to explore the new ideas and physics offered by nanostructures to implement advanced solar cell concepts such as hot carrier, multi-exciton and intermediate band solar cells. This special issue of Journal of Physics D: Applied Physics contains selected papers on nanostructured photovoltaics written by researchers in their respective fields of expertise. These papers capture the current excitement, as well as addressing some open questions in the field, covering topics including the III–V quantum well superlattice and quantum dot solar cells, Si quantum dot tandem cells, nanostructure-enhanced dye-sensitized solar cells and nanopatterned organic solar cells. We thank all the authors and reviewers for their contribution to this special issue. Special thanks are due to the journal's Publisher, Dr Olivia Roche and the editorial and publishing staff for their help and support.

Prevalence of Small-scale Jets from the Networks of the Solar Transition Region and Chromosphere  

E-Print Network (OSTI)

As the interface between the Sun's photosphere and corona, the chromosphere and transition region play a key role in the formation and acceleration of the solar wind. Observations from the Interface Region Imaging Spectrograph reveal the prevalence of intermittent small-scale jets with speeds of 80-250 km/s from the narrow bright network lanes of this interface region. These jets have lifetimes of 20-80 seconds and widths of 300 km or less. They originate from small-scale bright regions, often preceded by footpoint brightenings and accompanied by transverse waves with ~20 km/s amplitudes. Many jets reach temperatures of at least ~100000 K and constitute an important element of the transition region structures. They are likely an intermittent but persistent source of mass and energy for the solar wind.

Solar wind energy and momentum from the emergence of new small?scale flux  

Science Journals Connector (OSTI)

Recent Hinode observations have shown the remarkably rapid reconfiguration of the Sun’s small?scale magnetic flux. On the size?scale of granules solar magnetic flux is reconfigured over only 10 minutes. On the larger scales of supergranules magnetic flux is continually and rapidly reconfigured over about a day. We discuss how the reconfiguration processes observed by Hinode TRACE and SOHO may be related. The emergence of new magnetic flux continually drives reconnection between smaller emerging loops and overlying closed or open fields. Ultimately the energy and momentum from this emerging flux is converted into kinetic energy to drive the solar wind and thermal conductive and radiative energy in closed loops. Thus we describe the relationship between emerging small?scale magnetic flux and the momentum and energy that drives the solar wind and heats the corona.

Structural Code Considerations for Solar Rooftop Installations.  

SciTech Connect

Residential rooftop solar panel installations are limited in part by the high cost of structural related code requirements for field installation. Permitting solar installations is difficult because there is a belief among residential permitting authorities that typical residential rooftops may be structurally inadequate to support the additional load associated with a photovoltaic (PV) solar installation. Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure to a basic determinate beam. This method of analysis neglects the composite action of the entire roof structure, yielding a conservative analysis based on a rafter or top chord of a truss. Consequently, the analysis can result in an overly conservative structural analysis. A literature review was conducted to gain a better understanding of the conservative nature of the regulations and codes governing residential construction and the associated structural system calculations.

Zonal flows generated by small-scale drift-Alfven modes  

SciTech Connect

The generation of zonal flows by small-scale drift-Alfven (SSDA) modes is investigated. It is shown that these zonal flows can be generated by a monochromatic wave packet of SSDA modes propagating in the ion diamagnetic drift direction. The corresponding zonal-flow instability resembles a hydrodynamic one. Its growth rate depends on the spectrum purity of the wave packet; it decreases for relatively weak spectrum broadening and the instability turns into a resonant one, and eventually is suppressed, as the broadening increases. A general conclusion of this work is that the SSDA modes are less effective for driving zonal flows than standard drift modes.

Liquid dispersion and holdup in a small-scale upflow hydrotreater at high temperatures and pressure  

Science Journals Connector (OSTI)

Residence time distribution experiments were carried out at high temperatures and pressure in a small-scale upflow reactor. A diluted and a non-diluted bed were tested. Middle distillates and hydrogen were used as feeds. The axial dispersion model was used to describe the liquid flow through the packed bed. The dependency of Pe and liquid holdup on feed velocity and temperature was examined. The behaviour of the beds tested at hot flow conditions is compared with that of identical beds tested at ambient conditions using toluene as liquid feed and the effect of liquid-phase properties is discussed.

Legal obstacles and incentives to the development of small scale hydroelectric potential in Michigan  

SciTech Connect

The legal and institutional obstacles to the development of small-scale hydroelectric energy at the state level is described. The Federal government also exercises extensive regulatory authority in the area. The first obstacle which any developer must confront in Michigan is obtaining the authority to utilize the river bed, banks, and flowing water at a proposed dam site. This involves a determination of ownership of the stream banks and bed, and the manner of obtaining either their title or use; and existing constraints with regard to the use of the water. Michigan follows the riparian theory of water law. The direct regulation; indirect regulation; public utilities regulation; financing; and taxation are discussed.

Technology transfer of small-scale energy technologies in the US Pacific Territories  

SciTech Connect

From 1977 to 1981 the Department of Energy has awarded 32 grants for small-scale energy projects in the US Pacific Territories. A critical issue with these projects has been transferring the technology within the community once the project has been completed. Certain projects are more successful at this than others. There are elements common to projects which are the most successful in this regard. In addition, there appear to be five different types of technology transfer processes. This paper identifies these processes, illustrates each with a case study, and points out the common elements. Perhaps this information can be used when designing other projects to facilitate technology transfer in developing countries.

Legal obstacles and incentives to the development of small scale hydroelectric power in New York  

SciTech Connect

The legal and institutional obstacles to the development of small-scale hydroelectric energy at the state level are discussed. The Federal government also exercises extensive regulatory authority in the area, and the dual regulatory system from the standpoint of the appropriate legal doctrine, the law of pre-emption, application of the law to the case of hydroelectric development, and an inquiry into the practical use of the doctrine by the FERC is examined. The first step the small scale hydroelectric developer must take is that of acquiring title to the real property comprising the development site. The real estate parcel must include the requisite interest in the land adjacent to the watercourse, access to the underlying streambed and where needed, the land necessary for an upstream impoundment area. Land acquisition may be effectuated by purchase, lease, or grant by the state. In addition to these methods, New York permits the use of the eminent domain power of the state for public utilities under certain circumstances.

Small-scale instrumentation for nuclear magnetic resonance of porous media  

Science Journals Connector (OSTI)

The investigation of fluids confined to porous media is the oldest topic of investigation with small-scale nuclear magnetic resonance (NMR) instruments, as such instruments are mobile and can be moved to the site of the object, such as the borehole of an oil well. While the analysis was originally restricted by the inferior homogeneity of the employed magnets to relaxation measurements, today, portable magnets are available for all types of NMR measurements concerning relaxometry, imaging and spectroscopy in two types of geometries. These geometries refer to closed magnets that surround the sample and open magnets, which are brought close to the object for measurement. The current state of the art of portable, small-scale NMR instruments is reviewed and recent applications of such instruments are featured. These include the porosity analysis and description of diesel particulate filters, the determination of the moisture content in walls from gray concrete, new approaches to analyze the pore space and moisture migration in soil, and the constitutional analysis of the mortar base of ancient wall paintings.

Photovoltaic Materials  

SciTech Connect

The goal of the current project was to help make the US solar industry a world leader in the manufacture of thin film photovoltaics. The overall approach was to leverage ORNL’s unique characterization and processing technologies to gain a better understanding of the fundamental challenges for solar cell processing and apply that knowledge to targeted projects with industry members. ORNL has the capabilities in place and the expertise required to understand how basic material properties including defects, impurities, and grain boundaries affect the solar cell performance. ORNL also has unique processing capabilities to optimize the manufacturing process for fabrication of high efficiency and low cost solar cells. ORNL recently established the Center for Advanced Thin-film Systems (CATS), which contains a suite of optical and electrical characterization equipment specifically focused on solar cell research. Under this project, ORNL made these facilities available to industrial partners who were interested in pursuing collaborative research toward the improvement of their product or manufacturing process. Four specific projects were pursued with industrial partners: Global Solar Energy is a solar industry leader in full scale production manufacturing highly-efficient Copper Indium Gallium diSelenide (CIGS) thin film solar material, cells and products. ORNL worked with GSE to develop a scalable, non-vacuum, solution technique to deposit amorphous or nanocrystalline conducting barrier layers on untextured stainless steel substrates for fabricating high efficiency flexible CIGS PV. Ferro Corporation’s Electronic, Color and Glass Materials (“ECGM”) business unit is currently the world’s largest supplier of metallic contact materials in the crystalline solar cell marketplace. Ferro’s ECGM business unit has been the world's leading supplier of thick film metal pastes to the crystalline silicon PV industry for more than 30 years, and has had operational cells and modules in the field for 25 years. Under this project, Ferro leveraged world leading analytical capabilities at ORNL to characterize the paste-to-silicon interface microstructure and develop high efficiency next generation contact pastes. Ampulse Corporation is developing a revolutionary crystalline-silicon (c-Si) thin-film solar photovoltaic (PV) technology. Utilizing uniquely-textured substrates and buffer materials from the Oak Ridge National Laboratory (ORNL), and breakthroughs in Hot-Wire Chemical Vapor Deposition (HW-CVD) techniques in epitaxial silicon developed at the National Renewable Energy Laboratory (NREL), Ampulse is creating a solar technology that is tunable in silicon thickness, and hence in efficiency and economics, to meet the specific requirements of multiple solar PV applications. This project focused on the development of a high rate deposition process to deposit Si, Ge, and Si1-xGex films as an alternate to hot-wire CVD. Mossey Creek Solar is a start-up company with great expertise in the solar field. The primary interest is to create and preserve jobs in the solar sector by developing high-yield, low-cost, high-efficiency solar cells using MSC-patented and -proprietary technologies. The specific goal of this project was to produce large grain formation in thin, net-shape-thickness mc-Si wafers processed with high-purity silicon powder and ORNL's plasma arc lamp melting without introducing impurities that compromise absorption coefficient and carrier lifetime. As part of this project, ORNL also added specific pieces of equipment to enhance our ability to provide unique insight for the solar industry. These capabilities include a moisture barrier measurement system, a combined physical vapor deposition and sputtering system dedicated to cadmium-containing deposits, adeep level transient spectroscopy system useful for identifying defects, an integrating sphere photoluminescence system, and a high-speed ink jet printing system. These tools were combined with others to study the effect of defects on the performance of crystalline silicon and

Investment Timing and Capacity Choice for Small-Scale Wind PowerUnder Uncertainty  

SciTech Connect

This paper presents a method for evaluation of investments in small-scale wind power under uncertainty. It is assumed that the price of electricity is uncertain and that an owner of a property with wind resources has a deferrable opportunity to invest in one wind power turbine within a capacity range. The model evaluates investment in a set of projects with different capacity. It is assumed that the owner substitutes own electricity load with electricity from the wind mill and sells excess electricity back to the grid on an hourly basis. The problem for the owner is to find the price levels at which it is optimal to invest, and in which capacity to invest. The results suggests it is optimal to wait for significantly higher prices than the net present value break-even. Optimal scale and timing depend on the expected price growth rate and the uncertainty in the future prices.

Observations of small-scale plasma density depletions in arecibo HF heating experiments  

SciTech Connect

Observations of incoherent scattering of electromagnetic waves at UHF from Langmuir waves by a new scheme involving linear frequency modulation (chirping) of a UHF transmitter and the demodulation (dechirping) of the received signals have been applied during HF heating experiments. These observations show that the high power HF wave used for ionospheric modification creates small-scale plasma depletions instantly on a time scale of 5 ms. For a plasma frequency of 5.1 MHz, plasma frequency gradient of the order of 50 kHz/km, and power density input of the HF heater wave of 8.0 x 10/sup -5/ W/m/sup 2/ the depletion ranged from 3 to 5%. This appears to provide direct evidence that the HF-induced modifications involve Langmuir waves trapped in density cavities. copyrightAmerican Geophysical Union 1987

Approach to designing a solar concentrator for small-scale remote power application  

Science Journals Connector (OSTI)

A small-scale concentrated solar power (CSP) unit was designed to provide electricity and hot water using an organic Rankine cycle (ORC) for Egypt as part of an undergraduate capstone project. The system was designed for a target power output of 3 kW. It uses parabolic troughs to heat ethylene glycol used as the heat transfer fluid which absorbs heat in the trough collector and transfers it to the working fluid through a heat exchanger. The system consists of 9 parabolic troughs and a total aperture area of 67 m2 providing the required 3 kW of energy to the ORC. One parabolic trough was manufactured to test its thermal efficiency according to ASHRAE standard 93-2003 [Methods of Testing to Determine the Thermal Performance of Solar Collectors (ASHRAE Inc. 1791 Tullie Circle NE Atlanta GA 30329 2003)] and compared it to its calculated value. A simple microcontroller-based system was used to track the sun.

ORIGIN OF MACROSPICULE AND JET IN POLAR CORONA BY A SMALL-SCALE KINKED FLUX TUBE  

SciTech Connect

We report an observation of a small-scale flux tube that undergoes kinking and triggers the macrospicule and a jet on 2010 November 11 in the north polar corona. The small-scale flux tube emerged well before the triggering of the macrospicule and as time progresses the two opposite halves of this omega-shaped flux tube bent transversely and approach each other. After {approx}2 minutes, the two approaching halves of the kinked flux tube touch each other and an internal reconnection as well as an energy release takes place at the adjoining location and a macrospicule was launched which goes up to a height of 12 Mm. Plasma begins to move horizontally as well as vertically upward along with the onset of the macrospicule and thereafter converts into a large-scale jet in which the core denser plasma reaches up to {approx}40 Mm in the solar atmosphere with a projected speed of {approx}95 km s{sup -1}. The fainter and decelerating plasma chunks of this jet were also seen up to {approx}60 Mm. We perform a two-dimensional numerical simulation by considering the VAL-C initial atmospheric conditions to understand the physical scenario of the observed macrospicule and associated jet. The simulation results show that reconnection-generated velocity pulse in the lower solar atmosphere steepens into slow shock and the cool plasma is driven behind it in the form of macrospicule. The horizontal surface waves also appeared with shock fronts at different heights, which most likely drove and spread the large-scale jet associated with the macrospicule.

Small-scale turbulence affects the division rate and morphology of two red-tide dinoflagellates  

Science Journals Connector (OSTI)

The effects of small-scale turbulence on two species of dinoflagellates were examined in cultures where the turbulent forces came randomly from all directions and were intermittent both spatially and temporally; much like small-scale turbulence in the ocean. With Lingulodinium polyedrum (Stein) Dodge (syn. Gonyaulax polyedra), division rate increased linearly (from ?0.35 to 0.5 per day) and the mean cross-sectional area (CSA) decreased linearly (from ?1100 to 750 ?m2) as a function of the logarithmic increase in turbulence energy dissipation rate (?). These effects were noted when ? values increased between ?10?8 and 10?4 m2 s?3. However, when ? increased to ?10?3 m2 s?3, division rate sharply decreased and mean CSA increased. Over the same range of ?, Alexandrium catenella (Wheedon and Kofoid) Balech had its division rate decrease linearly (from ?0.6 to 0.45 per day) and its CSA increase linearly (from ?560 to 650 ?m2) as a function of the logarithmic increase in ?. Even at the highest ? examined (?10?3 m2 s?3), which may be unrealistically high for their ambits, both L. polyedra and A. catenella still had fairly high division rates, ?0.2 and 0.45 per day, respectively. Turbulence strongly affected chain formation in A. catenella. In non-turbulent cultures, the mode was single cells (80–90% of the population), but at ? of ?10?5 to 10?4 m2 s?3, the mode was 8 cells per chain. At the highest ? (?10?3 m2 s?3), the mode decreased to 4 cells per chain. The vertical distributions of A. catenella populations in relation to hydrographic flow fields were studied in the summers of 1997 and 1998 in East Sound, Washington, USA (latitude 48°39?N, 122°53?W). In both summers, high concentrations of A. catenella were found as a subsurface bloom in a narrow depth interval (?2 m), where both current shear and turbulence intensity were at a minimum. Other researchers have shown that A. catenella orients its swimming in shear flows, and that swimming speed increases with chain length. These responses, when combined with our observations, support a hypothesis that A. catenella actively concentrates at depths with low turbulence and shear.

Beyond heat baths: Generalized resource theories for small-scale thermodynamics  

E-Print Network (OSTI)

Small-scale heat exchanges have recently been modeled with resource theories intended to extend thermodynamics to the nanoscale and quantum regimes. We generalize these theories to exchanges of quantities other than heat, to baths other than heat baths, and to free energies other than the Helmholtz free energy. These generalizations are illustrated with "grand-potential" theories that model movements of heat and particles. Free operations include unitaries that conserve energy and particle number. From this conservation law and from resource-theory principles, the grand-canonical form of the free states is derived. States are shown to form a quasiorder characterized by free operations, d-majorization, the hypothesis-testing entropy, and rescaled Lorenz curves. We calculate the work distillable from, and we bound the work cost of creating, a state. These work quantities can differ but converge to the grand potential in the thermodynamic limit. Extending thermodynamic resource theories beyond heat baths, we open diverse realistic systems to modeling with one-shot statistical mechanics. Prospective applications such as electrochemical batteries are hoped to bridge one-shot theory to experiments.

The pretreatment process for BNFL, Inc.'s Hanford River Protection Project is to provide decontaminated low activity waste and concentrated eluate streams for vitrification into low and high activity waste glass, respectively. The pretreatment includes sludge washing, filtration, precipitation, and ion exchange processes to remove entrained solids, cesium, transuranics, technetium, and strontium. The cesium (Cs-137) and technetium (Tc-99) ion exchange removal is accomplished by using SuperLig 644, and 639 resins from IBC Advanced Technologies, American Fork, Utah. The resins were shown to selectively remove cesium and technetium (as anionic pertechnetate ) from alkaline salt solutions. The efficiency of ion exchange column loading and elution is a complex function involving feed compositions, equilibrium and kinetic behavior of ion exchange resins, diffusion, and the ionic strength and pH of the aqueous solution. A previous experimental program completed at the Savannah River Tech nology Center2 demonstrated the conceptualized flow sheet parameters with an Envelope C sample from Hanford Tank 241-AN-107. Those experiments also included determination of Cs and Tc batch distribution coefficients by SuperLig 644 and 639 resins and demonstration of small-scale column breakthrough and elution. The experimental findings were used in support of preliminary design bases and pretreatment flow sheet development by BNFL, Inc.

Inflation that runs naturally: Gravitational waves and suppression of power at large and small scales  

E-Print Network (OSTI)

We point out three correlated predictions of the axion monodromy inflation model: large amplitude of gravitational waves, suppression of power on horizon scales and on scales relevant for the formation of dwarf galaxies. While these predictions are likely generic to models with oscillations in the inflaton potential, the axion monodromy model naturally accommodates the required running spectral index through Planck-scale corrections to the inflaton potential. Applying this model to a combined data set of Planck, ACT, SPT, and WMAP low-$\\ell$ polarization cosmic microwave background (CMB) data, we find a best-fit tensor-to-scalar ratio $r_{0.05} = 0.07^{+0.05}_{-0.04}$ due to gravitational waves, which may have been observed by the BICEP2 experiment. Despite the contribution of gravitational waves, the total power on large scales (CMB power spectrum at low multipoles) is lower than the standard $\\Lambda$CDM cosmology with a power-law spectrum of initial perturbations and no gravitational waves, thus mitigating some of the tension on large scales. There is also a reduction in the matter power spectrum of 20-30\\% at scales corresponding to $k = 10~{\\rm Mpc}^{-1}$, which are relevant for dwarf galaxy formation. This will alleviate some of the unsolved small-scale structure problems in the standard $\\Lambda$CDM cosmology.

Department of Energy Small-Scale Hydropower Program: Feasibility assessment and technology development summary report  

SciTech Connect

This report summarizes two subprograms under the US Department of Energy's Small-Scale Hydroelectric Power Program. These subprograms were part of the financial assistance activities and included the Program Research and Development Announcement (PRDA) feasibility assessments and the technology development projects. The other major subprograms included engineering research and development, legal and institutional aspects, and technology transfer. These other subprograms are covered in their respective summary reports. The problems of energy availability and increasing costs of energy led to a national effort to develop economical and environmental attractive alternative energy resources. One such alternative involved the utilization of existing dams with hydraulic heads of <65 ft and the capacity to generate hydroelectric power of 15 MW or less. Thus, the PRDA program was initiated along with the Technology Development program. The purpose of the PRDA feasibility studies was to encourage development of renewable hydroelectric resources by providing engineering, economic, environmental, safety, and institutional information. Fifty-five feasibility studies were completed under the PRDA. This report briefly summarizes each of those projects. Many of the PRDA projects went on to become technology development projects. 56 refs., 1 fig., 2 tabs.

Magnetic reconnection between small-scale loops observed with the New Vacuum Solar Telescope  

E-Print Network (OSTI)

Using the high tempo-spatial resolution H$\\alpha$ images observed with the New Vacuum Solar Telescope, we report the solid observational evidence of magnetic reconnection between two sets of small-scale anti-parallel loops with an X-shaped topology. The reconnection process contains two steps: a slow step with the duration of more than several tens of minutes, and a rapid step lasting for only about three minutes. During the slow reconnection, two sets of anti-parallel loops reconnect gradually, and new loops are formed and stacked together. During the rapid reconnection, the anti-parallel loops approach each other quickly, and then the rapid reconnection takes place, resulting in the disappearance of former loops. In the meantime, new loops are formed and separate. The region between the approaching loops is brightened, and the thickness and length of this region are determined to be about 420 km and 1.4 Mm, respectively. During the rapid reconnection process, obvious brightenings at the reconnection site an...

Small-scale biomass gasification CHP utilisation in industry: Energy and environmental evaluation  

Science Journals Connector (OSTI)

Abstract Biomass gasification is regarded as a sustainable energy technology used for waste management and producing renewable fuel. Using the techniques of life cycle assessment (LCA) and net energy analysis this study quantifies the energy, resource, and emission flows. The purpose of the research is to assess the net energy produced and potential environmental effects of biomass gasification using wood waste. This paper outlines a case study that uses waste wood from a factory for use in an entrained flow gasification CHP plant. Results show that environmental impacts may arise from toxicity, particulates, and resource depletion. Toxicity is a potential issue through the disposal of ash. Particulate matter arises from the combustion of syngas therefore effective gas cleaning and emission control is required. Assessment of resource depletion shows natural gas, electricity, fossil fuels, metals, and water are all crucial components of the system. The energy gain ratio is 4.71MJdelivered/MJprimary when only electricity is considered, this increases to 13.94MJdelivered/MJprimary if 100% of the available heat is utilised. Greenhouse gas emissions are very low (7–15 g CO2-e/kWhe) although this would increase if the biomass feedstock was not a waste and needed to be cultivated and transported. Overall small-scale biomass gasification is an attractive technology if the high capital costs and operational difficulties can be overcome, and a consistent feedstock source is available.

Legal obstacles and incentives to the development of small scale hydroelectric power in Maryland  

SciTech Connect

The legal and institutional obstacles to the development of small-scale hydroelectric energy at the state level in Maryland are described. The Federal government also exercises extensive regulatory authority in the area. The dual regulatory system is examined with the aim of creating a more orderly understanding of the vagaries of the system, focusing on the appropriate legal doctrine, the law of pre-emption, application of the law to the case of hydroelectric development, and an inquiry into the practical use of the doctrine by the FERC. In Maryland, by common law rule, title to all navigable waters and to the soil below the high-water mark of those waters is vested in the state as successor to the Lord Proprietary who had received it by grant from the Crown. Rights to non-navigable water, public trust doctrine, and eminent domain are also discussed. Direct and indirect regulations, continuing obligations, loan programs, and regional organizations are described in additional sections.

Photovoltaic effects in  

Science Journals Connector (OSTI)

The theory and quantitative analysis of photovoltaic effects in an inhomogeneous semiconductor with a position-dependent energy gap in the presence of a temperature gradient are presented. Transport equations based on the thermodynamics of irreversible processes are used to develop the theory. The transformation of the initial equations and suitable assumption led to a formula revealing and arranging all photovoltaic effects occurring in a semiconductor. Four effects: the bulk photovoltaic Tauc effect; the mobility position-dependence photovoltaic effect; the thermophotovoltaic effect; and the classical Seebeck thermoelectric effect are revealed. Quantitative relations between particular effects and factors determining their significance are shown by means of numerical analysis and suitable diagrams.

Technical evaluation of a small-scale reverse osmosis desalination unit for domestic water  

Science Journals Connector (OSTI)

Tunisian standards for drinking water tolerate a maximum Total Dissolved Salts (TDS) of 1.5 g/L. The domestic water presents usually a salinity greater than 0.5 g/L. In the last few years, several small capacity reverse osmosis desalination prototypes have been marketed. They are used to desalinate brackish water with TDS lower than 1.5 g/L. The performances of such type of RO units with respect to the Tunisia tap waters are needed. A technico-economical evaluation of small-scale (100 L/day) reverse osmosis desalination unit has been studied. Water pre-treatment is composed of three filtration operations. Water is pumped through the RO membrane with maximum pressure of 6 bars. Before use, the desalinated water is treated with UV light. The salinity and the temperature of the tested domestic water are located respectively between 0.5 and 1.3 g/L and between 12 and 29°C. The pre-treatment allows eliminating all the suspension matters, as the turbidity and the Solid Density Index are reduced to zero FTU and surrounding one unit respectively. No chemicals are used in the pre-treatment, so membrane scaling can not be avoided if reject water presents a high scaling power. The supersaturation relative to calcium carbonate and gypsum were estimated for reject water. Their values indicate that the tested waters have no risk to scale the RO membrane. The recovery rate of the RO unit was evaluated vs. different operating conditions such as applied pressure, raw water TDS and water temperature. The small capacity unit was able to deliver a treated water of a 100 mg/L TDS with a conversion rate ranging between 25 and 37%. The water treatment cost was evaluated at 0.01 €/L which is roughly the tenth of that of bottled table water.

Roofs can also host photovoltaic (PV) modules that convert sunlight to electricity. In this study we assess the effects of installing a building integrated photovoltaic (BIPV) roof on an office building in Yuma, AZ. The system consists of thin film PV laminated to a white membrane, which lies above a layer of insulation. The solar absorptance of the roof decreased to 0.38 from 0.75 after installation of the BIPV, lowering summertime daily mean roof upper surface temperatures by about 5 °C. Summertime daily heat influx through the roof deck fell to ±0.1 kWh/m2from 0.3-1.0 kWh/m2. However, summertime daily heat flux from the ventilated attic into the conditioned space was minimally affected by the BIPV, suggesting that the roof was decoupled from the conditioned space. Daily PV energy production was about 25% of building electrical energy use in the summer. For this building the primary benefit of the BIPV appeared to be its capacity to generate electricity and not its ability to reduce heat flows into the building. Building energy simulations were used to estimate the cooling energy savings and heating energy penalties for more typical buildings.

Efficient scale for photovoltaic systems and Florida's solar rebate program  

Science Journals Connector (OSTI)

This paper presents a critical view of Florida's photovoltaic (PV) subsidy system and proposes an econometric model of PV system installation and generation costs. Using information on currently installed systems, average installation cost relations for residential and commercial systems are estimated and cost-efficient scales of installation panel wattage are identified. Productive efficiency in annual generating capacity is also examined under flexible panel efficiency assumptions. We identify potential gains in efficiency and suggest changes in subsidy system constraints, providing important guidance for the implementation of future incentive programs. Specifically, we find that the subsidy system discouraged residential applicants from installing at the cost-efficient scale but over-incentivized commercial applicants, resulting in inefficiently sized installations.

Atomistic modeling of nanowires, small-scale fatigue damage in cast magnesium, and materials for MEMS.  

SciTech Connect

Lightweight and miniaturized weapon systems are driving the use of new materials in design such as microscale materials and ultra low-density metallic materials. Reliable design of future weapon components and systems demands a thorough understanding of the deformation modes in these materials that comprise the components and a robust methodology to predict their performance during service or storage. Traditional continuum models of material deformation and failure are not easily extended to these new materials unless microstructural characteristics are included in the formulation. For example, in LIGA Ni and Al-Si thin films, the physical size is on the order of microns, a scale approaching key microstructural features. For a new potential structural material, cast Mg offers a high stiffness-to-weight ratio, but the microstructural heterogeneity at various scales requires a structure-property continuum model. Processes occurring at the nanoscale and microscale develop certain structures that drive material behavior. The objective of the work presented in this report was to understand material characteristics in relation to mechanical properties at the nanoscale and microscale in these promising new material systems. Research was conducted primarily at the University of Colorado at Boulder to employ tightly coupled experimentation and simulation to study damage at various material size scales under monotonic and cyclic loading conditions. Experimental characterization of nano/micro damage will be accomplished by novel techniques such as in-situ environmental scanning electron microscopy (ESEM), 1 MeV transmission electron microscopy (TEM), and atomic force microscopy (AFM). New simulations to support experimental efforts will include modified embedded atom method (MEAM) atomistic simulations at the nanoscale and single crystal micromechanical finite element simulations. This report summarizes the major research and development accomplishments for the LDRD project titled 'Atomistic Modeling of Nanowires, Small-scale Fatigue Damage in Cast Magnesium, and Materials for MEMS'. This project supported a strategic partnership between Sandia National Laboratories and the University of Colorado at Boulder by providing funding for the lead author, Ken Gall, and his students, while he was a member of the University of Colorado faculty.

Small-scale hydroelectric power demonstration project: Broad River Electric Cooperative, Inc. , Cherokee Falls Hydroelectric Project: Final technical and construction cost report  

SciTech Connect

The purpose of this report is to fulfill part of the requirement of the US Department of Energy (DOE) Cooperative Agreement Number FC07-80ID12125 of the Small Scale Hydropower Program and is submitted on behalf of the Broad River Electric Cooperative, Inc. of Gaffney, South Carolina. The project was initially studied in 1978 with construction commencing in January, 1984. The primary work elements of the project consisted of the renovation of an existing dam and a new powerhouse. The dam was rehabilitated and flashboards were installed along the top of the structure. The powerhouse was supplied with a single open pit turbine and a new substation was constructed. The project generated power in December of 1985 but has been plagued with numerous problems compounded by a flood in March, 1987 causing extensive damages. The flood of March, 1987 resulted in filing of litigative action by the developers against their project managers and engineers which has yet to reach settlement and will possibly culminate in court sometime during the fall of 1988.

Small-scale circulating fluidized bed combustor (CFBC) system for heat and power in remote areas  

SciTech Connect

Demand for heating and electric power has steadily increased in remote areas. The use of locally available fuel to achieve self sufficiency has become an important objective. Energy demands may require steam generation for district heating, power generation and process consumption. In addition, the steam generation unit can also be required to burn waste that includes MSW and sewage sludge. To meet these demands, new systems must be installed that use local fuel. This paper describes a lower cost CFBC for use in remote areas. With the support of DOE METC, in late summer 1994, DONLEE performed a test burn at its 10 MM btu/hr pilot CFBC using subbituminous coal from Wyoming. The Wyoming coal`s sulfur dioxide emissions were very low due to the low sulfur content of the Wyoming coal and the excellent efficiency at temperatures as low as 1,500 F thereby indicating no limestone addition was needed for sulfur capture. The CFBC testing indicated emissions met all of the environmental requirements, both Federal and state. These requirements include: particulates, SO{sub 2}, CO, NO{sub x}, opacity, chlorinated dioxins/furans, etc. The unit can be fabricated in modules, making the installation easier and less expensive for use in remote areas. The design is highly reliable and can be fully automated thereby requiring limited staffing.

A cross-sectional review: Impacts and sustainability of small-scale renewable energy projects in developing countries  

Science Journals Connector (OSTI)

Abstract Access to sustainable and affordable energy services is a crucial factor in reducing poverty in developing countries. In particular, small-scale and community-based renewable energy projects are recognized as important forms of development assistance for reaching the energy poor. However, to date only a few empirical evaluations exist which analyze and compare the impact of these projects on local living conditions and their sustainability ex-post implementation. To better understand the impacts and the conditions that influence sustainability of these projects, the research presented in this paper evaluated 23 local development projects post implementation. By applying an standardized evaluation design to a cross-sectional sample in terms of renewable energy sources (solar, wind, biomass, hydro), user needs (electricity, food preparation, lighting, productive uses), community management models, finance mechanisms and geographical locations, the review results provide valuable insights on the underlying conditions that influence the success or failure of these small-scale local energy interventions. The empirical evidence suggests that the sustainability of small-scale energy implementations (?100 kW) in developing countries is determined by the same factors, independent of the socio-cultural, political and ecological context. These findings allow to better predict the long-term success of small sustainable energy projects in developing countries, this can help to improve project designs and increase the certainty for future investment decisions.

Sun Valley Photovoltaic Power Project, Phase 1. Final report, June 1, 1978-February 28, 1979  

SciTech Connect

An application experiment was devised for fabrication, installation, operation, and evaluation of a concentrating photovoltaic system for direct conversion of sunlight to electricity. If the experiment is performed, the photovoltaic system will be connected to an electric motor load and to an electric utility system. Provisions will be made to allow the motor load to be supplied with power from either the photovoltaic system or the utility system. When the demand of the motor load is low, the photovoltaic system will deliver excess power to the utility system for use elsewhere. Thus, the experimental installation has been designed with sufficient flexibility to enable several modes of operation to be evaluated. This type of application is a typical example of on-site power generation at an individual load center involving two-way energy exchange with the adjacent utility system. Because a growing market for photovoltaic systems in this type of application is expected in the 1980's, the experiment will provide needed information in a timely manner. The experiment was devised jointly by the Los Angeles Department of Water and Power (LADWP) and its subcontractor, Spectrolab, Inc. LADWP will furnish a site and operate the equipment after installation. The subcontractor will manufacture and furnish a concentrating photovoltaic array with a power rating of approximately 200 kilowatts at one kilowatt per square meter of insolation. Other required equipment will be purchased to specification from appropriate suppliers. The photovoltaic system represents a state-of-the-art design at the time this report was prepared. However, minor design improvements may be made prior to and during system installation. All phases of fabrication, installation and operation will be documented through formal reports. The results of the experiment will contribute to the goals of the National Photovoltaic Conversion Program.

Photovoltaic power without batteries for continuous cathodic protection and an alternate photovoltaic/ultracapacitor combined power source  

SciTech Connect

The Coastal Systems Station (COASTSYSTA) designed, installed, and started up on 20 January 1990, a state-of-the-art stand-alone photovoltaic powered impressed current cathodic protection system (PVCPSYS) not requiring any backup power for steel and iron submerged structures. The PVCPSYS, installed on a 775-foot steel sheet piling of a Navy dock bulkhead, provides complete, continuous corrosion protection. The PVCPSYS has been in operation for more than five years, has not required any repair or maintenance, and is environmentally clean. Initial cost savings of the PVCPSYS versus conventional cathodic protection system was $46,000. A second PVCPSYS was installed on another 800-foot bulkhead on 21 May 1993. It is also providing complete corrosion protection without backup power. Performance is well documented. Other potential applications are moth-balled ships, locks, dams, bridges, pipelines, and similar structures. These systems are considered a major advance by Sandia and the Department of Defense (DOD) Photovoltaic Review Committee. An ultracapacitor, a recent hi-tech development that is environmentally clean, will be incorporated in the PVCPSYS when required to enhance the system`s capability. A photovoltaic/ultracapacitor (or equivalent) combined power source operating under adverse conditions, and/or to satisfy or meet regulations will assure cathodic protection, including pipelines carrying combustibles or other products that could otherwise create environmental problems. Patents are pending on this PVCPSYS and the photovoltaic/ ultracapacitor powered systems.

Comparative cost evaluation of heating oil and small-scale wood chips produced from Euro-Mediterranean forests  

Science Journals Connector (OSTI)

Abstract This work performs a cost evaluation of small-scale produced wood chips from forests in the Euro-Mediterranean region to be used for heating purposes. The study is focused on forests located in the Argençola municipality (Catalonia, northeastern Spain). The use of such easy-to-produce biofuel is appealing since it may be used as a valid substitute of heating oil to produce thermal energy in the same area where it is produced, thus minimizing transportation requirements and reducing dependence on the rising prices of heating oil. Additionally, it allows facing environmental and social concerns related to the current lack of management in the forests under analysis, which has led to an important increase in the biomass stock and wildfires risk. As wildfires in the Euro-Mediterranean region generate important impacts, an average economic cost of wildfires has been evaluated in this paper. The economic assessment of small-scale production and consumption of wood chips as proposed in this study has shown interesting economic benefits when compared with current heating oil prices. Results indicate that it is a realistic option since production costs range from 12.2 €/GJ to 18.5 €/GJ depending on the applied forestry practices, whereas current cost of heating oil is about 23.9 €/GJ. A sensitivity analysis has also been conducted to assess the impact of the data with higher uncertainty on the final results. It has been shown that the key factors that determine the viability of the proposed model are heating oil price, biomass stock growth rate, transportation requirements and applied forest management practices. Results presented prove that wood chips cost is quite independent of fossil fuel prices, thus higher fossil fuel prices greatly favors the use of wood chips when produced and consumed in the same area, thus minimizing transportation requirements. In addition, higher biomass growth rates than those considered in this work may reduce the final cost of small-scale produced wood chips.

Multijunction Photovoltaic Technologies for High-Performance Concentrators: Preprint  

SciTech Connect

Multijunction solar cells provide high-performance technology pathways leading to potentially low-cost electricity generated from concentrated sunlight. The National Center for Photovoltaics at the National Renewable Energy Laboratory has funded different III-V multijunction solar cell technologies and various solar concentration approaches. Within this group of projects, III-V solar cell efficiencies of 41% are close at hand and will likely be reported in these conference proceedings. Companies with well-developed solar concentrator structures foresee installed system costs of $3/watt--half of today's costs--within the next 2 to 5 years as these high-efficiency photovoltaic technologies are incorporated into their concentrator photovoltaic systems. These technology improvements are timely as new large-scale multi-megawatt markets, appropriate for high performance PV concentrators, open around the world.

Moreover, it considers photovoltaic (PV) conversion, the photovoltaic cell, and the performance evaluation of PV cells, module, panels and arrays that include: current?voltage (I–V) characteristics, power–voltage (P–V) characteristics. The chapter also studies the effect of irradiance on a PV cell voltage and current, the equivalent circuit of a solar cell, and the connection of the PV devices (parallel and series). The chapter explores ways of optimization PV arrays: maximum power point trackers, sun trackers, batteries' use, and proper matching with loads and solar concentration. It talks about photovoltaic systems: stand-alone and interactive, PV sizing of a stand-alone PV systems, PV applications, and utility interconnection issues and requirements.

Nanowires enabling strained photovoltaics  

SciTech Connect

Photovoltaic nano-devices have largely been relying on charge separation in conventional p-n junctions. Junction formation via doping, however, imposes major challenges in process control. Here, we report on a concept for photovoltaic energy conversion at the nano scale without the need for intentional doping. Our approach relies on charge carrier separation in inhomogeneously strained germanium nanowires (Ge NWs). This concept utilizes the strain-induced gradient in bandgap along tapered NWs. Experimental data confirms the feasibility of strain-induced charge separation in individual vapor-liquid-solid grown Ge NW devices with an internal quantum efficiency of ?5%. The charge separation mechanism, though, is not inherently limited to a distinct material. Our work establishes a class of photovoltaic nano-devices with its opto-electronic properties engineered by size, shape, and applied strain.

Evolution of small-scale magnetic elements in the vicinity of granular-size swirl convective motions  

E-Print Network (OSTI)

Advances in solar instrumentation have led to a widespread usage of time series to study the dynamics of solar features, specially at small spatial scales and at very fast cadences. Physical processes at such scales are determinant as building blocks for many others occurring from the lower to the upper layers of the solar atmosphere and beyond, ultimately for understanding the bigger picture of solar activity. Ground-based (SST) and space-borne (Hinode) high-resolution solar data are analyzed in a quiet Sun region displaying negative polarity small-scale magnetic concentrations and a cluster of bright points observed in G-band and Ca II H images. The studied region is characterized by the presence of two small-scale convective vortex-type plasma motions, one of which appears to be affecting the dynamics of both, magnetic features and bright points in its vicinity and therefore the main target of our investigations. We followed the evolution of bright points, intensity variations at different atmospheric heig...

PRACTICAL APPLICATIONS OF PHOTOVOLTAICS IN AGRICULTURE AND HORTICULTURE  

Science Journals Connector (OSTI)

1. ABSTRACT The direct conversion of solar radiation into electricity is one of the promissing techniques of energy supply in remote areas. But also in industrialized regions like in Central Europe with a well developed electricity grid one could find a lot of econimic applications of photovoltaics even for a price of 5 ? 8 US Y/Wp. The German Ministry of Research and Technology has initiated a series of demonstration projects of photovoltaics. Our institute is responsible for some of them for agricultural and horticultural applications. At the moment several plants with an electric power in the range 35 W ? 150 W for irrigation of an experimental ecological garden, a series of allotments and a field for growing vegetables are planned. Further installations will provide drinking water for sheep, cattle and deer on the pasture. Within this program two projects for ventilation and lighting of fish ponds with a peak power of 1 kW will be built. Very interesting is the application of solar panels as power supply for remote stables. There is a power demand for milking machine, water pumping, freezing protection, lighting, electric tools, ventilation of pig stables and for small drying installations for hay and grain. Preliminary experiments on water pumping were performed but have to be extended to provide better design data. 2. KEYWORDS Photovoltaics in agriculture, solar water pumping, irrigation, photovoltaics for ventilation, power supply of remote stables, ventilation of fish ponds.

Photovoltaic power without batteries for continuous cathodic protection and an alternate photovoltaic/ultracapacitor combined power source  

SciTech Connect

The Coastal Systems Station (COASTSYSTA) designed, installed, and started up on 20 January 1990, a state-of-the-art stand alone photovoltaic powered impressed current cathodic protection system (PVCPSYS) not requiring any backup power for steel and iron submerged structures. The PVCPSYS, installed on a 775-foot steel sheet piling of a Navy dock bulkhead, provides complete, continuous corrosion protection. The PVCPSYS has been in operation for more than four years, has not required any repair or maintenance, and is environmentally clean. Initial cost savings of the PVCPSYS versus conventional cathodic protection system was $46,000. A second PVCPSYS was installed on another 800-foot bulkhead on 21 May 1993. It is also providing complete corrosion protection without backup power. These systems are considered a major advance by Sandia and the Department of Defense (DOD) Photovoltaic Review Committee. An ultracapacitor, a recent hi-tech development that is environmentally clean, will be incorporated in the PVCPSYS when required to enhance the system`s capability. A photovoltaic/ultracapacitor (or equivalent) combined power source operating under adverse conditions, and/or to satisfy or meet regulations will assure cathodic protection, including pipelines carrying combustibles or other products that could otherwise create environmental problems. Patents are pending on this PVCPSYS and the photovoltaic/ultracapacitor powered systems. The objective of the initial project was to successfully demonstrate that renewable energy can efficiently and economically replace, or be used instead of, continuous nonrenewable power sources. An opportunity to cleanly show that photovoltaic power is practical and reliable was the result of a recommendation to provide cathodic protection to the Naval Diving and Salvage Training Center bulkhead.

Redrawing the solar map of South Africa for photovoltaic applications  

Science Journals Connector (OSTI)

The South African solar map has been redrawn to make it applicable to photovoltaic installations. This has been done with the aim of reducing the cost of solar PV installations in South Africa through accurate energy resource assessment and competent system design. Climate data software as well as solar design software was used to aid this process. The new map provides an alternative to the map in current use, which only considers radiation, whereas many more factors affect the output of a panel, such as wind, cloud cover and humidity. All these are taken into account when drawing the new map.

Characteristic Requirements of a Small Scale Squirrel Cage Induction Generator for Effective Electricity Generation from Wind Energy  

Science Journals Connector (OSTI)

Abstract This paper proposes characteristic requirements of a small scale squirrel cage induction generator for effective electricity generation from wind energy. These characteristics are obtained from modeling and testing results. Investigation into comparative performances between Standard and high efficiency induction generators is given in order to find out the characteristic requirements of a suitable induction generator. Performances of various features of the machine structure are given. The suitable design of the induction generator based on empirical rules is also included. The investigation of power loss of the induction machine both in theory using FEM (Finite Element Method) and tests has been made. In addition, static var (Volt-Ampere reactive power) compensator using power electronic control to keep terminal voltage of a self-excited induction generator constant is explained. These results can be guidelines for machine development and control method for effective electricity generation.

FEMP--Photovoltaics  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Photovoltaics is a technology that converts radiant Photovoltaics is a technology that converts radiant light energy (photo) to electricity (voltaics). Photo- voltaic (PV) cells are the basic building blocks of this energy technology. PV cells (also called solar cells) are made of semicon- ductor materials, most typically silicon. The amount of electricity a PV cell produces depends on its size, its conversion efficiency (see box on reverse), and the intensity of the light source. Sunlight is the most common source of the energy used by PV cells to produce an electric current. It takes just a few PV cells to produce enough elec- tricity to power a small watch or solar calculator. For more power, cells are connected together to form larger units called modules. Modules, in turn, are connected to form arrays, and arrays can be

Temperature compensated photovoltaic array  

DOE Patents (OSTI)

A temperature compensated photovoltaic module comprises a series of solar cells having a thermally activated switch connected in parallel with several of the cells. The photovoltaic module is adapted to charge conventional batteries having a temperature coefficient differing from the temperature coefficient of the module. The calibration temperatures of the switches are chosen whereby the colder the ambient temperature for the module, the more switches that are on and form a closed circuit to short the associated solar cells. By shorting some of the solar cells as the ambient temperature decreases, the battery being charged by the module is not excessively overcharged at lower temperatures. PV module is an integrated solution that is reliable and inexpensive. 2 figs.

Evaluation of the photovoltaic generation potential and real-time analysis of the photovoltaic panel operation on a building facade in southern Brazil  

Science Journals Connector (OSTI)

Abstract Solar photovoltaic systems are an alternative to the current model of power generation, supplying clean energy with little environmental impact and no significant losses associated with distribution networks. This study aims to obtain data on electricity generation in real time for a photovoltaic panel installed in the city of Lajeado, Rio Grande do Sul, Brazil, comparing the electric power generation of the photovoltaic panel with the solar radiation data of the city, obtained with the use of a pyranometer. Data from incident solar radiation, measured in the city, on the period of 2007–2012 were used. Comparisons with data from power generation of the photovoltaic panel and assessment of the solar potential were performed. The photovoltaic panel has an area of 16.5 m2 and was installed on the campus of UNIVATES University Center, arranged so that it faces the true north and tilted at an angle of 24°, for better utilization of solar radiation incident along the year. At the end of this phase of the study, it was obtained an average power generation of 11.0 kWh/day and efficiency of the modules in the order of 12.6%.

A study on lubricant oil supply for positive-displacement expanders in small-scale organic Rankine cycles  

Science Journals Connector (OSTI)

Abstract Positive-displacement expanders, which are widely used in small-scale \\{ORCs\\} (Organic Rankine Cycles), need reliable LOS (Lubricant Oil Supply) to get well lubrication and sealing. In the present paper, the characteristics of two traditional LOS schemes are examined. Moreover, a modified one is proposed. Analyses of those elements that lead to work loss of lubricant oil supply have been carried out for all the three LOS schemes. The work loss of lubricant oil supply, which is caused by the employment of lubricant oil pumps, pressure drop in lubricant oil separator and other components contributing to work loss, is evaluated by a definition of WLLS (Work Loss Factor of Lubrication Oil Supply). Based on the thermodynamic model of ORC established, the calculation methods of WLLS are presented. Through analyses of LOS schemes and calculation of WLLS in two typical ORCs, it was found that the traditional LOS schemes either can not work reliably, or might cause up to 11.5% and 9.5% power decrease. The values can be reduced by half in the proposed LOS scheme, which can also work reliably. Accompanied with the advantages, the defects of the new scheme were also investigated.

Small scale laboratory studies of flow and transport phenomena in pores and fractures: Phase 2. Technical completion report  

SciTech Connect

Pore level laboratory experiments using microscopy permit the in situ visualization of flow and transport phenomena, that can be recorded on film or videotape. One of the principal tools for visualization is the etched glass micromodel, which is composed of a transparent two dimensional network of three dimensional pores. The spatial scale of interest in these models extends from the individual pore, up to a network of pores, perhaps with small scale heterogeneities. Micromodels are best used to help validate concepts and assumptions, and to elucidate new, previously unrecognized phenomena for further study. They are not quantitative tools, but should be used in combination with quantitative tools such as column studies or mathematical models. There are three applications: multi-phase flow, colloid transport, and bacterial transport and colonization. Specifically the authors have examined behavior of relevance to liquid-liquid mass transfer (solubilization of capillary trapped organic liquids); liquid-gas mass transfer (in situ volatilization); mathematical models of multi-phase pressure-saturation relationships; colloid movement, attachment and detachment in the presence of fluid-fluid interfaces, clay interference with multi-phase flow; and heterogeneity effects on multi-phase flow and colloid movement.

Dynamic performance estimation of small-scale solar cogeneration with an organic Rankine cycle using a scroll expander  

Science Journals Connector (OSTI)

Small-scale solar thermal cogeneration shows promise as an effective way to get increased benefit out of a given solar availability, since it does not waste potential during summer after the water capacity is heated. In this paper a scroll expander is tested in a small organic Rankine cycle (ORC) and used to calibrate a static expander model. Validation of the scroll expander model shows agreement generally within 10% for the shaft power, 5% for the rotational speed and 6 K for the exhaust temperature, with some outliers at very low pressure ratios. This calibrated model is then incorporated into a larger dynamic model of a solar thermal cogeneration system, designed for some larger dwelling unit or small commercial establishment that requires a larger volume of hot water. An annual simulation is conducted using a collector area of 50 m2, and the scroll expander shows a maximum isentropic efficiency of 59% while the ORC efficiency is 3.47%. The total energy produced is 1710 kWh and the hot water available is on average 2540 L/day. The maximum instantaneous power that can be produced by the system is 676 W, and it is possible to shift the time period that the system is producing power to match the peak demand period by adjusting the solar store volume.

Floating Piston Expander Development for a Small?Scale Collins Type 10 K Cryocooler for Space Applications  

Science Journals Connector (OSTI)

Future spacecraft cooling and sensing systems will require advanced multi?stage cryocoolers capable of providing continuous cooling at multiple temperature levels ranging from 10 K to 95 K. Stirling and pulse?tube cryocoolers have achieved compactness and reliability by adopting mechanically simple cold head configurations at the expense of thermodynamic efficiency. Large?scale terrestrial cryogenic refrigerators achieve much higher efficiencies by employing complex designs but their high efficiency is not retained at the small scale required for spacecraft cryogenic cooling. AMTI in collaboration with MIT is developing a multi?stage 10 K cryocooler that applies modern microelectronic sophistication to achieve high efficiency in a reliable compact design. The cryocooler is based upon a novel modification of the Collins cycle a cycle commonly used in many high?efficiency terrestrial cryogenic machines. Innovations of the design include floating piston expanders and electro?magnetic smart valves which eliminate the need for mechanical linkages and reduce the input power size and weight of the cryocooler in an affordable modular design. This paper will present the design of the first generation prototype the results of development testing and the direction of future development efforts.

Small-scale mantle heterogeneity on the source of the Gran Canaria (Canary Islands) Pliocene–Quaternary magmas  

Science Journals Connector (OSTI)

New chemical and Sr–Nd–Pb isotopic data of the Plio-Quaternary mafic lavas of Gran Canaria are used to investigate their mantle source composition. The most prominent aspects of the new dataset are the slight isotopic differences between the Plio-Quaternary (Post-Roque Nublo Group) and the older Pliocene (Roque Nublo Group) mafic parental magmas, which reflect small-scale mantle heterogeneities. Melting of two mantle materials, one isotopically more depleted and similar to the Depleted Mantle (DM) and the other with more radiogenic Pb-isotope ratios comparable to a mantle with high U/Pb ratio (HIMU), accounts for the isotopic and trace element composition of the Pliocene–Quaternary magmas of Gran Canaria. Geochemical variations show that the Pliocene–Quaternary mantle source is compositionally and lithologically heterogeneous and supports the presence of a silica-deficient pyroxenite mantle component. The contribution of the pyroxenite component in the generation of the Roque Nublo and Post-Roque Nublo magmas is estimated to be in the range from 50 to 70%. Trace element ratios support mixing between the two mantle components (pyroxenite veins in a peridotite matrix) which obscure the original chemical and isotopic composition of these two end-members.

The results of a series of telephone interviews with groups of users of information on photovoltaics (PV) are described. These results, part of a larger study on many different solar technologies, identify types of information each group needed and the best ways to get information to each group. The report is 1 of 10 discussing study results. The overall study provides baseline data about information needs in the solar community. It covers these technological areas: photovoltaics, passive solar heating and cooling, active solar heating and cooling, biomass energy, solar thermal electric power, solar industrial and agricultural process heat, wind energy, ocean energy, and advanced energy storage. An earlier study identified the information user groups in the solar community and the priority (to accelerate solar energy commercialization) of getting information to each group. In the current study only high-priority groups were examined. Results from seven PV groups respondents are analyzed in this report: DOE-Funded Researchers, Non-DOE-Funded Researchers, Researchers Working for Manufacturers, Representatives of Other Manufacturers, Representatives of Utilities, Electric Power Engineers, and Educators.

NREL Center for Photovoltaics  

ScienceCinema (OSTI)

Solar cells, also called photovoltaics (PV) by solar cell scientists, convert sunlight directly into electricity. Solar cells are often used to power calculators and watches. The performance of a solar cell is measured in terms of its efficiency at turning sunlight into electricity. Only sunlight of certain energies will work efficiently to create electricity, and much of it is reflected or absorbed by the material that make up the cell. Because of this, a typical commercial solar cell has an efficiency of 15%?about one-sixth of the sunlight striking the cell generates electricity. Low efficiencies mean that larger arrays are needed, and that means higher cost. Improving solar cell efficiencies while holding down the cost per cell is an important goal of the PV industry, researchers at the National Renewable Energy Laboratory (NREL) and other U.S. Department of Energy (DOE) laboratories, and they have made significant progress. The first solar cells, built in the 1950s, had efficiencies of less than 4%. For a text version of this video visit http://www.nrel.gov/learning/re_photovoltaics_video_text.html

Analysis of design variables for an efficient natural gas steam reforming process comprised in a small scale hydrogen fueling station  

Science Journals Connector (OSTI)

Natural gas steam reforming process comprised in a small scale H2-fueling station for on-site hydrogen production was simulated and analyzed. The effects of process variables on the process efficiency of hydrogen production were investigated, and their optimum set point values were suggested to minimize the sizes of the process sub-units and to secure a stable operability of the reforming process. Steam to carbon (S/C) ratio of the reforming reactants was found to be a crucial parameter mostly governing both the hydrogen production efficiency and the stable operability of the process. In this study, a process run was assumed stable if feed water (WR) as a reforming reactant could have been completely evaporated into dry steam through a heat recovery steam generator (HRSG). The optimum S/C ratio was 3.0 where the process efficiency of hydrogen production was maximized and the stable operability of the process was secured. The optimum feed rates of natural gas (NGR) and WR as reforming reactants and of natural gas (NGB) as a burner fuel were also determined for a target rate of hydrogen production, 27 Nm3/h. Set point temperatures of the combustion flue gas (CFG) and the reformed gas (RFG) from the reformer had no effects on the hydrogen production efficiency, however, they were important parameters affecting the stable operability of the process. The effect of the set point temperatures of the RFG from cooler and the CFG from HRSG on the hydrogen production efficiency was not much significant as compared to the S/C ratio, but needed to be adjusted because of their considerable effects on the stable operability of the process and the required heat transfer areas in cooler and HRSG.

Investigations of ash fouling with cattle wastes as reburn fuel in a small-scale boiler burner under transient conditions  

SciTech Connect

Fouling behavior under reburn conditions was investigated with cattle wastes (termed as feedlot biomass, FB) and coal as reburn fuels under a transient condition and short-time operation. A small-scale (30 kW or 100,000 Btu/hr) boiler burner research facility was used for the reburn experiments. The fuels considered for these experiments were natural gas (NG) for the ashless case, pure coal, pure FB, and blends of coal and FB. Two parameters that were used to characterize the ash 'fouling' were (1) the overall heat-transfer coefficient (OHTC) when burning NG and solid fuels as reburn fuels, and (2) the combustible loss through ash deposited on the surfaces of heat exchanger tubes and the bottom ash in the ash port. A new methodology is presented for determining ash fouling behavior under transient conditions. Results on the OHTCs for solid reburn fuels are compared with the OHTCs for NG. It was found that the growth of the layer of ash depositions over longer periods typically lowers OHTC, and the increased concentration of ash in gas phase promotes radiation in high-temperature zones during initial periods while decreasing the heat transfer in low-temperature zones. The ash analyses indicated that the bottom ash in the ash port contained a smaller percentage of combustibles with a higher FB percentage in the fuels, indicating better performance compared with coal because small particles in FB burn faster and the FB has higher volatile matter on a dry ash-free basis promoting more burn out. 16 refs., 12 figs., 6 tabs.

High-temperature hydrogen-air-steam detonation experiments in the BNL small-scale development apparatus  

SciTech Connect

The Small-Scale Development Apparatus (SSDA) was constructed to provide a preliminary set of experimental data to characterize the effect of temperature on the ability of hydrogen-air-steam mixtures to undergo detonations and, equally important, to support design of the larger scale High-Temperature Combustion Facility (HTCF) by providing a test bed for solution of a number of high-temperature design and operational problems. The SSDA, the central element of which is a 10-cm inside diameter, 6.1-m long tubular test vessel designed to permit detonation experiments at temperatures up to 700K, was employed to study self-sustained detonations in gaseous mixtures of hydrogen, air, and steam at temperatures between 300K and 650K at a fixed initial pressure of 0.1 MPa. Hydrogen-air mixtures with hydrogen composition from 9 to 60 percent by volume and steam fractions up to 35 percent by volume were studied for stoichiometric hydrogen-air-steam mixtures. Detonation cell size measurements provide clear evidence that the effect of hydrogen-air gas mixture temperature, in the range 300K-650K, is to decrease cell size and, hence, to increase the sensitivity of the mixture to undergo detonations. The effect of steam content, at any given temperature, is to increase the cell size and, thereby, to decrease the sensitivity of stoichiometric hydrogen-air mixtures. The hydrogen-air detonability limits for the 10-cm inside diameter SSDA test vessel, based upon the onset of single-head spin, decreased from 15 percent hydrogen at 300K down to between 9 and 10 percent hydrogen at 650K. The one-dimensional ZND model does a very good job at predicting the overall trends in the cell size data over the range of hydrogen-air-steam mixture compositions and temperature studied in the experiments.

Science Journals Connector (OSTI)

It is an inevitable trend for China to develop green technologies to help the country to produce cleaner energy and to consume it more efficiently under the pressure of energy security concern the nation’s emissions trajectory and sustainable economic development. The abundant solar resources in West China provide a big potential to utilize the solar energy. Under the promotion of key incentive policies including both feed-in-tariff (FIT) mechanisms and government rebate programs China has become a major global solar force in photovoltaic (PV) industry both in manufacturing and in the installation of flat-plate products with 16 GW production and 2.75 GW installation achieved in the year 2011. As a branch of PV technology concentrating photovoltaics (CPV) technology with several years’ development history in China is presently moving from pilot facilities to commercial-scale applications. Several MW-CPV power plants have been installed by both domestic and western companies in China factories with several hundred-MW production capacity are being planned or built. Sustainable performance and reliability improvement of CPV modules a vertical integration of supply chain in CPV industry aiming at a cost reduction a sufficient grid infrastructure for facilitating the West-East and North-South electricity transmission will promote Chinese CPV market to actually initiate develop and mature.

The factors (environmental benefits, health benefits, network benefits, need for new production capacity, etc.) promoting solar or other renewable sources of electricity in other countries are also present in Canada, but effective policy mechanisms to stimulate Canada's photovoltaic industry are only starting to appear. Discussions of policy options focused initially on renewable portfolio standards and then on feed-in tariffs. This paper reviews the Japanese and Australian experience with capital incentives to stimulate the residential market for photovoltaics. It demonstrates the ability of a market-sensitive program to stimulate industrial growth, achieve unit cost reductions and shift the market to include a large grid-tied share. Residential respondents to surveys report high costs as their primary barrier to installing photovoltaic systems and state a strong preference for capital incentives to reduce their investment costs. The Canadian government needs a market stimulation policy if it is to join those countries where a decentralized photovoltaic generation system strengthens the electricity supply system. A balanced solar energy market stimulation program is proposed that combines a feed-in tariff with a declining capital incentive.

Photovoltaic cell assembly  

DOE Patents (OSTI)

A photovoltaic assembly for converting high intensity solar radiation into lectrical energy in which a solar cell is separated from a heat sink by a thin layer of a composite material which has excellent dielectric properties and good thermal conductivity. This composite material is a thin film of porous Al.sub.2 O.sub.3 in which the pores have been substantially filled with an electrophoretically-deposited layer of a styrene-acrylate resin. This composite provides electrical breakdown strengths greater than that of a layer consisting essentially of Al.sub.2 O.sub.3 and has a higher thermal conductivity than a layer of styrene-acrylate alone.

Photovoltaic solar concentrator  

DOE Patents (OSTI)

A photovoltaic solar concentrator is disclosed with one or more transverse-junction solar cells (also termed point contact solar cells) and a lens located above each solar cell to concentrate sunlight onto the solar cell to generate electricity. Piezoelectric actuators tilt or translate each lens to track the sun using a feedback-control circuit which senses the electricity generated by one or more of the solar cells. The piezoelectric actuators can be coupled through a displacement-multiplier linkage to provide an increased range of movement of each lens. Each lens in the solar concentrator can be supported on a frame (also termed a tilt plate) having three legs, with the movement of the legs being controlled by the piezoelectric actuators.

Small-Scale Water Ingression and Crust Strength Tests (SSWICS) SSWICS-6 test data report : thermal hydraulic results, Rev. 0.  

SciTech Connect

The Melt Attack and Coolability Experiments (MACE) program at Argonne National Laboratory addressed the issue of the ability of water to cool and thermally stabilize a molten core/concrete interaction (MCCI) when the reactants are flooded from above. These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching. However, due to the integral nature of these tests, several questions regarding the crust freezing behavior could not be adequately resolved. These questions include: (1) To what extent does water ingression into the crust increase the melt quench rate above the conduction-limited rate and how is this affected by melt composition and system pressure? (2) What is the fracture strength of the corium crust when subjected to a thermal-mechanical load and how does it depend upon the melt composition? A series of separate-effects experiments are being conducted to address these issues. The first employs an apparatus designed to measure the quench rate of a pool of corium ({approx} {phi} 30 cm; up to 20 cm deep). The main parameter to be varied in these quench tests is the melt composition since it is thought to have a critical influence on the crust cracking behavior which, in turn, alters quench rate. The issue of crust strength is being addressed with a second apparatus designed to mechanically load the crust produced by the quench tests. This apparatus measures the fracture strength of the crust while it is either at room temperature or above, the latter state being achieved with a heating element placed below the crust. The two apparatuses used to measure the melt quench rate and crust strength are jointly referred to as SSWICS (Small-Scale Water Ingression and Crust Strength). This report describes results of the sixth water ingression test, designated SSWICS-6. This test investigated the quenching behavior of a fully oxidized PWR corium melt containing 15 wt% siliceous concrete at a system pressure of 1 bar absolute. The report includes a description of the test apparatus, the instrumentation used, plots of the recorded data, and some rudimentary data reduction to obtain an estimate of the heat flux from the corium to the overlying water pool.

A two dimensional thermal network model for a photovoltaic solar wall  

SciTech Connect

A two dimensional thermal network model is proposed to predict the temperature distribution for a section of photovoltaic solar wall installed in an outdoor room laboratory in Concordia University, Montreal, Canada. The photovoltaic solar wall is constructed with a pair of glass coated photovoltaic modules and a polystyrene filled plywood board as back panel. The active solar ventilation through a photovoltaic solar wall is achieved with an exhaust fan fixed in the outdoor room laboratory. The steady state thermal network nodal equations are developed for conjugate heat exchange and heat transport for a section of a photovoltaic solar wall. The matrix solution procedure is adopted for formulation of conductance and heat source matrices for obtaining numerical solution of one dimensional heat conduction and heat transport equations by performing two dimensional thermal network analyses. The temperature distribution is predicted by the model with measurement data obtained from the section of a photovoltaic solar wall. The effect of conduction heat flow and multi-node radiation heat exchange between composite surfaces is useful for predicting a ventilation rate through a solar ventilation system. (author)

Thin film photovoltaic panel and method  

DOE Patents (OSTI)

A thin film photovoltaic panel includes a backcap for protecting the active components of the photovoltaic cells from adverse environmental elements. A spacing between the backcap and a top electrode layer is preferably filled with a desiccant to further reduce water vapor contamination of the environment surrounding the photovoltaic cells. The contamination of the spacing between the backcap and the cells may be further reduced by passing a selected gas through the spacing subsequent to sealing the backcap to the base of the photovoltaic panels, and once purged this spacing may be filled with an inert gas. The techniques of the present invention are preferably applied to thin film photovoltaic panels each formed from a plurality of photovoltaic cells arranged on a vitreous substrate. The stability of photovoltaic conversion efficiency remains relatively high during the life of the photovoltaic panel, and the cost of manufacturing highly efficient panels with such improved stability is significantly reduced.

Solar Installation Labor Market Analysis  

SciTech Connect

The potential economic benefits of the growing renewable energy sector have led to increased federal, state, and local investments in solar industries, including federal grants for expanded workforce training for U.S. solar installers. However, there remain gaps in the data required to understand the size and composition of the workforce needed to meet the demand for solar power. Through primary research on the U.S. solar installation employer base, this report seeks to address that gap, improving policymakers and other solar stakeholders understanding of both the evolving needs of these employers and the economic opportunity associated with solar market development. Included are labor market data covering current U.S. employment, expected industry growth, and employer skill preferences for solar installation-related occupations. This study offers an in-depth look at the solar installation sectors. A study published by the Solar Foundation in October 2011 provides a census of labor data across the entire solar value chain.

Photovoltaic solar concentrator module  

SciTech Connect

This invention consists of a planar photovoltaic concentrator module for producing an electrical signal from incident solar radiation which includes an electrically insulating housing having a front wall, an opposing back wall and a hollow interior. A solar cell having electrical terminals is positioned within the interior of the housing. A planar conductor is connected with a terminal of the solar cell of the same polarity. A lens forming the front wall of the housing is operable to direct solar radiation incident to the lens into the interior of the housing. A refractive optical element in contact with the solar cell and facing the lens receives the solar radiation directed into the interior of the housing by the lens and directs the solar radiation to the solar cell to cause the solar cell to generate an electrical signal. An electrically conductive planar member is positioned in the housing to rest on the housing back wall in supporting relation with the solar cell terminal of opposite polarity. The planar member is operable to dissipate heat radiated by the solar cell as the solar cell generates an electrical signal and further forms a solar cell conductor connected with the solar cell terminal to permit the electrical signal generated by the solar cell to be measured between the planar member and the conductor.

25 Year Lifetime for Flexible Buildings Integrated Photovoltaics  

SciTech Connect

Although preliminary proof-of-principle of the efficacy of barrier materials and processes, first developed by Battelle at PNNL and commercialized by Vitex, has been demonstrated at the laboratory scale, there are several challenges to the practical commercial implementation of these developments in the Buildings Integrated Photovoltaics (BIPV) market. Two important issues that are addressed in this project are identifying a low cost substrate material that can survive in the outside environment (rain, heat, dust, hail, etc.) for 25 years and developing an encapsulation method for the photovoltaic (PV) cells that can meet the required barrier performance without driving the cost of the total barrier package out of range (remaining below $3.00/Wp). Without these solutions, current encapsulation technologies will limit the use of PV for BIPV applications. Flexible, light-weight packaging that can withstand 25 years in the field is required for a totally flexible integrated PV package. The benefit of this research is to make substantial progress in the development of a cost-effective, viable thin film barrier package which will be a critical enabling technology to meet the Solar America Initiative cost and device reliability goals, and to make photovoltaics (PV) more cost-competitive with electricity generated using fossil fuels. Increased PV installations will enable increased US electrical capacity and reduce dependence on imported oil through increased utilization of a widely abundant source of renewable energy (sunlight).

Process Development for Nanostructured Photovoltaics  

SciTech Connect

Photovoltaic manufacturing is an emerging industry that promises a carbon-free, nearly limitless source of energy for our nation. However, the high-temperature manufacturing processes used for conventional silicon-based photovoltaics are extremely energy-intensive and expensive. This high cost imposes a critical barrier to the widespread implementation of photovoltaic technology. Argonne National Laboratory and its partners recently invented new methods for manufacturing nanostructured photovoltaic devices that allow dramatic savings in materials, process energy, and cost. These methods are based on atomic layer deposition, a thin film synthesis technique that has been commercialized for the mass production of semiconductor microelectronics. The goal of this project was to develop these low-cost fabrication methods for the high efficiency production of nanostructured photovoltaics, and to demonstrate these methods in solar cell manufacturing. We achieved this goal in two ways: 1) we demonstrated the benefits of these coatings in the laboratory by scaling-up the fabrication of low-cost dye sensitized solar cells; 2) we used our coating technology to reduce the manufacturing cost of solar cells under development by our industrial partners.

Empirically Derived Strength of Residential Roof Structures for Solar Installations.  

SciTech Connect

Engineering certification for the installation of solar photovoltaic (PV) modules on wood roofs is often denied because existing wood roofs do not meet structural design codes. This work is intended to show that many roofs are actually sufficiently strong given the conservatism in codes, documented allowable strengths, roof structure system effects, and beam composite action produced by joist-sheathing interaction. This report provides results from a testing program to provide actual load carrying capacity of residential rooftops. The results reveal that the actual load carrying capacity of structural members and systems tested are significantly stronger than allowable loads provided by the International Residential Code (IRC 2009) and the national structural code found in Minimum Design Loads for Buildings and Other Structures (ASCE 7-10). Engineering analysis of residential rooftops typically ignores the system affects and beam composite action in determining rooftop stresses given a potential PV installation. This extreme conservatism combined with conservatism in codes and published allowable stress values for roof building materials (NDS 2012) lead to the perception that well built homes may not have adequate load bearing capacity to enable a rooftop PV installation. However, based on the test results presented in this report of residential rooftop structural systems, the actual load bearing capacity is several times higher than published values (NDS 2012).

Photovoltaic Technology Basics Photovoltaic Technology Basics Photovoltaic Technology Basics August 16, 2013 - 4:47pm Addthis Text Version Photovoltaic (PV) materials and devices convert sunlight into electrical energy, and PV cells are commonly known as solar cells. Photovoltaics can literally be translated as light-electricity. First used in about 1890, "photovoltaic" has two parts: photo, derived from the Greek word for light, and volt, relating to electricity pioneer Alessandro Volta. And this is what photovoltaic materials and devices do-they convert light energy into electrical energy, as French physicist Edmond Becquerel discovered as early as 1839. Becquerel discovered the process of using sunlight to produce an electric current in a solid material. But it took more than another century to truly

High Penetration Photovoltaic Case Study Report  

SciTech Connect

Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

Next-Generation Photovoltaic Technologies

Next-Generation Photovoltaic Next-Generation Photovoltaic Technologies Next-Generation Photovoltaic Technologies Print Monday, 06 February 2012 15:48 Organic solar cells based on the polymer/fullerene bulk heterojunction (BHJ) model represent one of the most promising technologies for next-generation solar energy conversion due to their low cost and scalability. Traditional organic photovoltaics (OPVs) are thought to have interpenetrating networks of pure polymer and fullerene layers with discrete interfaces. Researchers at Argonne National Laboratory, working with collaborators from the University of Chicago, LBNL, and NIST, used ALS Beamline 11.0.1.2 to perform resonant soft x-ray scattering (RSoXS) on PTB7/fullerene BHJ solar cells to probe performance-related structures at different length scales. These solar cells set a historic record of conversion efficiency (7.4%). The RSoXS demonstrated that the superior performance of PTB7/fullerene solar cells is attributed to surprising hierarchical nanomorphologies ranging from several nanometers of crystallites to tens of nanometers of nanocrystallite aggregates in intermixed PTB7-rich and fullerene-rich domains, themselves hundreds of nanometers in size. This work will lead the research community to rethink ideal OPV morphologies, reconsider which structures should be targeted in OPVs, and enable the rational design of even higher-performance organic solar cells.

Steady-State Screening-Photovoltaic Spatial Solitons in the  

Science Journals Connector (OSTI)

The theory of the screening-photovoltaic solitons is improved in biased photorefractive-photovoltaic crystals. When the photovoltaic effect is negligible, the screening-photovoltaic solitons are the screening ones, and their space-charge field is the space-charge field of the screening solitons. If the external field is absent, the screening-photovoltaic solitons are the photovoltaic ones on the open- and closed-circuit conditions, and their space-charge field is of the photovoltaic solitons. We also show theoretically that the screening and the photovoltaic solitons on the open- and closed-circuit conditions may be studies together as the screening-photovoltaic solitons.

EDIA-EISCAT comparison between small scale F-region irregularities and large scale electron density structures at sub-auroral latitudes  

Science Journals Connector (OSTI)

Small scale sub-auroral F-region irregularities were observed on 6–7 February 1984 by the two HF radars of the EDIA experiment while the EISCAT UHF system was scanning the ionosphere between 57° and 66° invariant latitude at a slightly different longitude. The bistatic EDIA system was mainly designed to detect the F-region irregularities at sub-auroral latitudes and to measure their perpendicular velocities. This paper is devoted to an examination of the morphology of the irregularity regions detected by the HF radars and of their production mechanisms, by comparison with the horizontal and vertical electron density profiles measured by EISCAT. It is shown that decametric irregularities observed at about 360–430 km height are not associated with any large scale horizontal density gradients in the F-region (350km). However, a strong north-south gradient observed at lower altitudes (150–200km), which is likely to indicate the southern boundary of the high energy particle precipitation zone, is well correlated with the strong scattering regions observed by the HF radars. The EISCAT electron temperature measurements at 350km height also show horizontal gradients which are well correlated with the small scale F-region irregularities. We discuss implications of these observations on the mechanisms of production of irregularities in the sub-auroral F-region.
