Energy research and development profile of Australia  

SciTech Connect

Australia is a large, sparsely populated country with an economy based traditionally on raw materials exports. Though still a major international trader in minerals and agricultural products, Australia has suffered a decline in productivity, employment, exports, and economic growth since the 1950s. Most energy research and development (R and D) and policymaking activities are carried out under the National Energy Research, Development, and Demonstration (NERDD) program. The NERDD program priorities include, among others, production of liquid hydrocarbon fuels from natural gas or coal-derived synthesis gas and oil and gas exploration, assessment, and recovery technology (high priority); production of liquid fuels from coal and oil shale by hydrogenation or pyrolysis, coal gasification, and achievement of cost reductions in coal and oil shale exploration and assessment techniques (medium priority); and in-situ coal gasification (low priority). Bilateral agreements for energy R and D with other countries are carried out under the Australian Department of National Development and Energy. Australia currently has agreements related to oil, gas, shale, and coal liquids R and D with the UK, the US, Japan, and West Germany.

statistics and information agency. The Institute’s mission is better health and wellbeing for Australians through better health and welfare statistics and information. The Australasian Association of Cancer Registries (AACR) is a collaborative body representing state and territory cancer registries in Australia and New Zealand. Most are members of the International Association of Cancer Registries. The AACR was formed in November 1982 to provide a formal mechanism for promoting uniformity of collection, classification and collation of cancer data. The objectives of the AACR are to: • Achieve national agreement on cancer-specific data definitions and coding and to encourage compliance with such agreements. As far as possible, data definitions and coding should be consistent with existing International Association of Cancer Registries (IACR) protocols and conventions. Facilitate the production of Australian, state and territory and national statistical publications on cancer that are comparable with each other and with international statistical publications. Improve the operational efficiency, and data completeness and quality, of the state and territory and New Zealand cancer registries through collaborative sharing of information. Contribute to national cancer control development in Australia and New Zealand through the regular and timely publication of local and national cancer statistics and the provision of data for cancer control research and health promotion. Contribute national data to international publications of the IACR. Contribute to international cancer coding and statistical analysis developments via members ’ involvement with IACR. Facilitate national epidemiological research projects on cancer (given appropriate local and AIHW ethics committee approvals).CANCER SERIES Number 28

Geothermal development in Australia  

DOE Green Energy (OSTI)

In Australia, natural hot springs and hot artesian bores have been developed for recreational and therapeutic purposes. A district heating system at Portland, in the Otway Basin of western Victoria, has provided uninterrupted service for 12 Sears without significant problems, is servicing a building area of 18 990 m{sup 2}, and has prospects of expansion to manufacturing uses. A geothermal well has provided hot water for paper manufacture at Traralgon, in the Gippsland Basin of eastern Victoria. Power production from hot water aquifers was tested at Mulka in South Australia, and is undergoing a four-year production trial at Birdsville in Queensland. An important Hot Dry Rock resource has been confirmed in the Cooper Basin. It has been proposed to build an HDR experimental facility to test power production from deep conductive resources in the Sydney Basin near Muswellbrook.

Cutting Australia’s Carbon Abatement Costs with Nuclear Power  

E-Print Network (OSTI)

The Australian Government Treasury modelling of a carbon price shows that Australia must purchase the benefits of overseas abatement efforts if it is to meet its emission reduction target by 2050. That is, foreign abatement will be required to supplement domestic abatement efforts. If more domestic abatement were available, fewer foreign credits would be needed. As an example, the analysis here shows that for the core Treasury policy scenario, Australia could save up to $185 billion net in abatement costs by 2050 if 25 gigawatts of nuclear generation capacity were built instead of building new fossil fuel generators.

Residential Water Conservation in Australia and California  

E-Print Network (OSTI)

In much of the Western United States, reducing residential water use is a major source of water conservation, especially as population growth urbanizes agricultural land. While estimates of the potential of conservation are useful, the experience of Australia provides a realistic target for residential water conservation. Although reliability of urban water use data is often questionable, it is clear that Australians use less water than Californians, with a similar climate, economy, and culture. Per-capita usage is compared, and explanations for use differences are offered. If California had the same residential water use rates as Australia, it could have reduced gross urban water use by 2,600 GL (2.1 million acre-feet) in 2009 and potentially saved 1,800 GL (1.5 million acre-feet) for consumptive use by others.

Goodwyn project under way off NW Australia  

SciTech Connect

This paper reports that the $2 billion (Australian) Goodwyn field development project on Australia's Northwest Shelf is under way with installation of a 17,500 metric ton steel platform jacket. Northwest Shelf project operator Woodside Petroleum Pty. Ltd. and partners are continuing with an extensive exploration program in the Northwest Shelf area. The group expects to begin soon a wide ranging 3-D seismic survey over the WA-28-P license area and the Northwest Shelf production permits. The goal is to identify new and appraise existing oil and gas prospects in the region for an exploratory drilling campaign to begin in first half 1993. Finding more gas reserves would bode well for extending existing LNG contracts with Japan or competing for new markets in Japan, South Korea, and Taiwan.

Evidence of progress. Measurement of impacts of Australia's S and L program from 1990-2010  

Science Conference Proceedings (OSTI)

Australia first put categorical energy efficiency labels on residential appliances in the mid-1980s, and the first Minimum Energy Performance Standards (MEPS) for refrigerators was implemented in 1999. Updated in 2005, these MEPS were aligned with US 2001 levels. Considered together, these actions set Australia apart as having one of the most aggressive appliance efficiency programs in the world. For these reasons, together with good data on product sales over time, Australia represents a potentially fruitful case study for understanding the dynamics energy efficiency standards and labeling (EES and L) programs impacts on appliance markets. This analysis attempts to distinguish between the impacts of labeling alone as opposed to MEPS, and to probe the time-dependency of such impacts. Fortunately, in the Australian case, detailed market sales data and a comprehensive registration system provides a solid basis for the empirical evaluation of these questions. This paper analyzes Australian refrigerator efficiency data covering the years 1993-2009. Sales data was purchased from a commercial market research organization (in this case, the GfK Group) and includes sales and average price in each year for each appliance model – this can be used to understand broader trends by product class and star rating category, even where data is aggregated. Statistical regression analysis is used to model market introduction and adoption of high efficiency refrigerators according to logistic adoption model formalism, and parameterizes the way in which the Australian programs accelerated adoption of high-efficiency products and phased out others. Through this analysis, the paper presents a detailed, robust and quantitative picture of the impacts of EES and L in the Australian case, but also demonstrates a methodology of the evaluation of program impacts that could form the basis of an international evaluation framework for similar programs in other countries.

Beginning of an oil shale industry in Australia  

Science Conference Proceedings (OSTI)

This paper discusses how preparations are being made for the construction and operation of a semi commercial plant to process Australian oil shale. This plant is primarily designed to demonstrate the technical feasibility of processing these shales at low cost. Nevertheless it is expected to generate modest profits even at this demonstration level. This will be the first step in a three staged development of one of the major Australian oil shale deposits which may ultimately provide nearly 10% of Australia's anticipated oil requirements by the end of the century. In turn this development should provide the basis for a full scale oil shale industry in Australia based upon the advantageously disposed oil shale deposits there. New sources of oil are becoming critical since Australian production is declining rapidly while consumption is accelerating.

The contribution that Australian universities make to research training in Australia a) Contribution of research training programs to Australia’s competitiveness in the areas of science, research and innovation Australian universities are clearly the primary research training platform in regards to science, research and innovation. Commonwealth research training scheme funding is accessed by The University of Notre Dame Australia (UNDA) to provide, primarily, relief from tuition fees for higher degree by research students. Only a very minimal amount of RTS funding is used to fund skills acquisition and professional development for research active staff and students at UNDA. Other programs within UNDA that are linked to RTS include a limited injection of funding into student research project costs and general research capacity building. UNDA has undergone a sustained growth in its research student population; our enrolled research students have increased seven-fold between 2002 and 2008. RTS funding has significantly supported this growth and, as a result, the capacity to support research in other ways has remained limited. One example of where the University has achieved success on a limited budget has been in the implementation of a “Research Incentive Scheme ” that rewards research output and acts as a catalyst for future research initiatives. In the context of seeking to achieve excellence in niche research UNDA has expanded its research program in the

Structural evolution of the Permian-Triassic Cooper basin, Australia: Relation to hydrocarbon trap styles  

SciTech Connect

The structural and depositional history of the Cooper basin in eastern central Australia has revealed that the basin is a mildly compressional structural depression controlled by northwestrending and northeast-trending pre-Permian basement features. Pronounced pre-Permian compressions are indicated by northeast-trending major structures, the Gidgealpa-Merrimelia-Innamincka and Murteree-Nappacoongee trends. Detailed chronostratigraphic facies analysis, with closely spaced palynological control, of the Patchawarra Formation revealed that two pronounced phases of uplift occurred during the Sakmarian. The major intrabasin highs were rejuvenated during these tectonic events, as documented by crestal unconformities (middle and upper Patchawarra unconformities). Evidence of each event is dominantly tectonic in character, with similar depositional patterns over these highs related to each event. These events are also recognizable in midflank areas and basin margins with contemporaneous deposition in deeper parts of the basin. Results from this research show potential for future hydrocarbon discoveries within structural, stratigraphic, and structural/stratigraphic traps in the Cooper basin. Various trap styles are closely associated with faults, unconformities, and lateral facies changes. Lowside fault closures, onlap plays, and unconformity traps are expected to be well developed along intrabasinal highs, basin margins, and preexisting structures. The primary reservoir targets would be deltaic sequences comprising shoreline sandstones, distributary and delta-mouth bar deposits that may be well developed in synclinal areas, and flanks of intrabasin highs in the Copper basin.

APPLICATIONS OF GIS IN COMMUNITY-BASED FOREST MANAGEMENT IN AUSTRALIA (AND NEPAL) By  

E-Print Network (OSTI)

Community forestry is now a popular approach in forest management globally. Although local communities have previously been involved in forest management in various minor ways, community-based forestry is very new in the Australian context. Because of the multiple interests of forest users and other community interest groups, a wider range of up-to-date information is being requested in community forestry, than has been used in ‘conventional ’ government-based forest management in the past. The overall aim of this research was to explore the potential and constraints for the application of Geographic Information System (GIS) technology in community forest management in Australia and to relate the results also to Nepal. Specific objectives were to: (i) review the applications of GIS in forestry and community forestry worldwide, (ii) determine stakeholders ’ views on their requirements for the use of GIS in community-based forest management, (iii) prepare and demonstrate various practical applications of GIS requested by community groups in the Wombat State Forest, (iv) identify the strengths and limitations of GIS in community forestry, and (v) relate findings on GIS

OTEC thermal resource report for Dampier Land, Australia  

DOE Green Energy (OSTI)

The region off Dampier Land, Australia was selected for study as a potential OTEC site. The region examined was between 13--18/sup 0/ South latitude and 118--121/sup 0/ East longitude. Data coverage was sparse, but the existing data demonstrated a fine potential for Ocean Thermal Energy Conversion (OTEC) use. The maximum temperature gradient remains relatively stable throughout the year. The annual average ..delta..T at 1000 meters is 22.6/sup 0/C. At 600 meters, an annual average ..delta..T greater than 20/sup 0/C is obtainable. The continental shelf off Dampier Land is very wide; thus, the distance to water 1500 meters deep may be as much as 480 kilometers (260 nautical miles). Water 1000 meters deep lies at least 265 kilometers (143 nautical miles) offshore. This distance is a major problem, perhaps necessitating the use of a plant ship. Tropical storms can be a problem between December and April. The ocean off Dampier Land has an upper mixed layer throughout the year. Currents are generally moderate, although the surface circulation pattern changes during the year.

Electric power industry restructuring in Australia: Lessons from down-under. Occasional paper No. 20  

SciTech Connect

Australia`s electric power industry (EPI) is undergoing major restructuring. This restructuring includes commercialization of state-owned electric organization through privatization and through corporatization into separate governmental business units; structural unbundling of generation, transmission, retailing, and distribution; and creation of a National Electricity Market (NEM) organized as a centralized, market-based trading pool for buying and selling electricity. The principal rationales for change in the EPI were the related needs of enhancing international competitiveness, improving productivity, and lowering electric rates. Reducing public debt through privatization also played an important role. Reforms in the EPI are part of the overall economic reform package that is being implemented in Australia. Enhancing efficiency in the economy through competition is a key objective of the reforms. As the need for reform was being discussed in the early 1990s, Australia`s previous prime minister, Paul Keating, observed that {open_quotes}the engine which drives efficiency is free and open competition.{close_quotes} The optimism about the economic benefits of the full package of reforms across the different sectors of the economy, including the electricity industry, is reflected in estimated benefits of a 5.5 percent annual increase in real gross domestic product and the creation of 30,000 more jobs. The largest source of the benefits (estimated at 25 percent of total benefits) was projected to come from reform of the electricity and gas sectors.

Health impact assessment in Australia: A review and directions for progress  

Science Conference Proceedings (OSTI)

This article provides an overview of Health Impact Assessment (HIA) within Australia. We discuss the development and current position of HIA and offer some directions for HIA's progression. Since the early 1990s HIA activity in Australia has increased and diversified in application and practice. This article first highlights the emergent streams of HIA practice across environmental, policy and health equity foci, and how these have developed within Australia. The article then provides summaries of current practice provided by each Australian state and territory. We then offer some insight into current issues that require further progression or resolution if HIA is to progress effectively in Australia. This progress rests both on developing broad system support for HIA across government, led by the health sector, and developing system capacity to undertake, commission or review HIAs. We argue that a unified and clear HIA approach is required as a prerequisite to gaining the understanding and support for HIA in the public and private sectors and the wider community.

Laurentia, Australia, and Antarctica as a Late Proterozoic supercontinent. Constraints from isotopic mapping  

Science Conference Proceedings (OSTI)

The reconstruction of Laurentia, Australia, and Antarctica into a Proterozoic supercontinent is evaluated by analyzing the fit of Precambrian provinces defined by isotopic and geochronologic mapping. The analysis is complicated by allochthonous segments of the Antarctic and eastern Australian margins. Removal of the allochthonous provinces produces a closer fit of the continents; there is a match of Early Proterozoic basement between southwestern Laurentia and the only exposure of craton known from the paleo-Pacific margin of Antarctica. In addition, western Laurentia is brought closer to the Australian Gawler block, consistent with provenance interpretations of the Belt Supergroup. Removal of the allochthonous provinces by right-lateral translation relative to the Antarctic craton margin places them in a pre-750 Ma position where they could be southwestward extensions of the Yavapai-Mazatzal and Grenville provinces of southern Laurentia. This modified reconstruction leads to a prediction of extensive Archean basement in Antarctica between the South Pole and Victoria Land, a prediction partly borne out by Archean rocks in the Miller Range of the Transantarctic Mountains; it also predicts the presence of 1.4 Ga rapakivi granites in the Transantarctic Mountains basement. This configuration implies assembly of the Australia-Antarctica Gondwana margin by terrane accretion following, or accompanied by, left-lateral translation. 27 refs., 2 figs., 1 tab.

The correlation of 27 day period solar activity and daily maximum temperature in continental Australia  

E-Print Network (OSTI)

We report the first observation of a 27 day period component in daily maximum temperature recorded at widely spaced locations in Australia. The 27 day component, extracted by band pass filtering, is correlated with the variation of daily solar radio flux during years close to solar minimum. We demonstrate that the correlation is related to the emergence of regions of solar activity on the Sun separated, temporally, from the emergence of other active regions. In this situation, which occurs only near solar minimum, the observed 27 day variation of temperature can be in phase or out of phase with the 27 day variation of solar activity. During solar maximum correlation of temperature and solar activity is much less defined. The amplitude of the 27 day temperature response to solar activity is large, at times as high as 6 degrees C, and much larger than the well documented temperature response to the 11 year cycle of solar activity. We demonstrate that the 27 day temperature response is localised to the Australia...

Estimating parameters of coalescing compact binaries with a detector network including LIGO Australia  

E-Print Network (OSTI)

One of the goals of gravitational-wave astronomy is simultaneous detection of gravitational-wave signals from merging compact-object binaries and the electromagnetic transients from these mergers. With the next generation of advanced ground-based gravitational wave detectors under construction, we examine the benefits of the proposed extension of the detector network to include a fourth site in Australia in addition to the network of Hanford, Livingston and Cascina sites. Using Bayesian parameter-estimation analyses of simulated gravitational-wave signals from a range of coalescing-binary locations and orientations, we study the improvement in parameter estimation. We find that an Australian detector can break degeneracies in several parameters; in particular, the localization of the source on the sky is improved by a factor of ~4, with more modest improvements in distance and binary inclination estimates. This enhanced ability to localize sources on the sky will be crucial in any search for electromagnetic c...

We find that an Australian detector can break degeneracies in several parameters; in particular, the localization of the source on the sky is improved by a factor of ~4, with more modest improvements in distance and binary inclination estimates. This enhanced ability to localize sources on the sky will be crucial in any search for electromagnetic counterparts to detected gravitational-wave signals.

NABERS: Lessons from 12 Years of Performance Based Ratings in Australia  

E-Print Network (OSTI)

The National Australian Built Environment Rating System (NABERS) has been operating for 12 years as a performance based rating system for the energy/greenhouse efficiency of office buildings in Australia. During this period, the scheme has been expanded to include performance based energy and water ratings for offices, hotels and shopping centres, plus performance based rating tools for office indoor environment and waste. NABERS has achieved significant success in transforming the energy efficiency of the office building stock, particularly with respect to the landlord operated services in the higher-quality end of the market. NABERS ratings have become established as a core valuation in the market for sale or lease of these buildings. The declaration of NABERS ratings has recently become mandatory for commercial sale and lease transactions over 2000m2. In this paper, the history of the NABERS scheme is outlined, with particular emphasis on the key lessons learnt and the underlying factors that have contributed to successes and failures along the way. Directions for future development are also discussed.

"Minimalist model of ice microphysics in mixed-phase stratiform clouds." Geophysical Research Letters, 40(14), doi:10.1002/grl.50700. Nordic winter landscape. Mixed-phase stratiform clouds are common features in the Arctic environment. They contain a mix of ice and "supercooled" water that, despite the freezing temperatures, remains in liquid form. Scientists aren't sure why these clouds exist in the Arctic for long periods of time, even while steadily losing ice particles through precipitation.

Giants in the Sky Giants in the Sky For original submission and image(s), see ARM Research Highlights http://www.arm.gov/science/highlights/ Research Highlight A few large particles in a crowd of tiny ones have often been ignored when calculating the amount of sunlight bounced back into space in clean-sky conditions. Scientists at Pacific Northwest National Laboratory found that these "giant" particles have a larger-than-expected impact on the amount of sunlight reflected away from Earth, by as much as 45 percent. They also showed that particles larger than one micron (0.000039 inch) occur much more frequently than expected, up to 85 percent of the time. "Many routine measurements are unable to sample large particles, thus they may overlook the residence of many 'Gullivers in the country of Lilliput,' said Dr. Evgueni

Native Students and the Gains from Exporting Higher Education: Evidence from Australia  

E-Print Network (OSTI)

This paper proposes a general equilibrium model with non-pro…t publicly subsidized universities to show that native applicants do not have to lose from exporting higher education, as suggested by standard trade models. The gains from exporting higher education that initially accrue to universities will be redistributed to natives through increased investment in research and teaching. With Australian university-level data from 2001 to 2007, the empirical investigation identi…es the impact of exporting higher education on native enrollment using the instrumental variable approach: the enrollment of one more foreign student leads to the enrollment of about 0.75 more Australian native students.

Author manuscript, published in "12th Conference of International Building Performance Simulation Association, Sydney: Australia (2011)" IMPACT OF THE CLIMATE ON THE DESIGN OF LOW-ENERGY BUILDINGS  

E-Print Network (OSTI)

The work presented in this paper aims to compare two different climates in Australia and Reunion Island and to identify the similarities in terms of bioclimatic design of low energy building. This approach is to perform a real evaluation of the sensation of thermal comfort in the workplace for different climates on the basis of the "bioclimatic chart " developed by Baruch Givoni. This article discusses the comparison of the thermal comfort levels obtained in the same building located in Australia and Reunion Island for different climatic zones. Both countries are influenced by the ocean and the altitude but are located at very different latitudes. Australia is a large area with several types of climate: temperate in south-eastern and south-west, desert or semi-arid in most parts of the territory, and tropical climate in the northern zone of the continent. Reunion has a tropical climate that can be affected by the altitude. Bioclimatic design strategies are different for wet and dry tropical climates, but in terms of targets at low energy, some basic principles can be identical and can be applied around the world. If a building is well designed and well adapted to its local climate, it is possible to apply the same design rules and standards for all buildings and two for these two different climates.

Climate change vulnerability assessments as catalysts for social learning: four case studies in south-eastern Australia  

SciTech Connect

Technical assessments of vulnerability and/or risk are increasingly being undertaken to assess the impacts of climate change. Underlying this is the belief that they will bring clarity to questions regarding the scale of institutional investments required, plausible adaptation policies and measures, and the timing of their implementation. Despite the perceived importance of technical assessments in 'evidence-based' decision environments, assessments cannot be undertaken independent of values and politics, nor are they capable of eliminating the uncertainty that clouds decision-making on climate adaptation As such, assessments can trigger as many questions as they answer, leaving practitioners and stakeholders to question their value. This paper explores the value of vulnerability/risk assessments in climate change adaptation planning processes as a catalyst for learning in four case studies in Southeastern Australia. Data were collected using qualitative interviews with stakeholders involved in the assessments and analysed using a social learning framework. This analysis revealed that detailed and tangible strategies or actions often do not emerge directly from technical assessments. However, it also revealed that the assessments became important platforms for social learning. In providing these platforms, assessments present opportunities to question initial assumptions, explore multiple framings of an issue, generate new information, and galvanise support for collective actions. This study highlights the need for more explicit recognition and understanding of the important role social learning plays in climate change vulnerability assessments and adaptation planning more broadly.

The history of HDR research and development  

DOE Green Energy (OSTI)

An energy source rivaling the sun exists in the form of the heat emanating from the interior of the earth. Although limited quantities of this geothermal energy are produced today by bringing natural hot fluids to the surface, most of the earth`s heat is trapped in hot dry rock (HDR). The application of hydraulic fracturing technology to tap this vast HDR resource was pioneered by Los Alamos National Laboratory beginning in 1970. Since that time, engineered geothermal reservoirs have been constructed and operated at numerous locations around the world. Major work at the US HDR facility at Fenton Hill, NM, and at the British HDR site in Cornwall, UK, has been completed, but advanced HDR field work continues at two sites on the island of Honshu in Japan and at Soultz in northeastern France. In addition, plans are currently being completed for the construction of an HDR system on the continent of Australia. Over the past three decades the worldwide research and development effort has taken HDR from its early conceptual stage to its present state as a demonstrated technology that is on the verge of becoming commercially feasible. Extended flow tests in the United States, Japan, and Europe have proven that sustained operation of HDR reservoirs is possible. In support of these field tests, an international body of scientists and engineers have pursued a variety of innovative approaches for assessing HDR resources, constructing and characterizing engineered geothermal reservoirs, and operating HDR systems. Taken together, these developments form a strong base upon which to build the practical HDR systems that will provide clean energy for the world in the 21st century.
