Thermoelectric materials offer an opportunity for economic recovery of the waste heat from exhaust gases to reduce operational costs and CO2 emissions. An increase in thermoelectric conversion efficiency of a few percent, in power production, would translate to significant cost saving on a national scale, which is about several billions of Australian dollars worth of products per year in this area alone. Energy efficiency and clean, renewable energy will mean a stronger economy, a cleaner environment and greater energy independence for Australia. Success of this program will facilitate the development of thermoelectric materials and renewable energy technologies, which have enormous national and international markets.Read moreRead less

Long-term mechanical-flow performance of an enhanced geothermal reservoir. The project aims to improve methods to generate power from geothermal energy. Extraction of heat from deep earth is promising but so far inefficient. Heat is transferred when water is pumped underground, but recovery of heat is low and much water is lost. This project aims to investigate carbon dioxide (CO2) as an alternative to water. There are excellent prospects of relatively efficient recovery, and any loss of CO2 in ....Long-term mechanical-flow performance of an enhanced geothermal reservoir. The project aims to improve methods to generate power from geothermal energy. Extraction of heat from deep earth is promising but so far inefficient. Heat is transferred when water is pumped underground, but recovery of heat is low and much water is lost. This project aims to investigate carbon dioxide (CO2) as an alternative to water. There are excellent prospects of relatively efficient recovery, and any loss of CO2 in deep-earth geothermal reservoirs is beneficial because it represents permanent sequestration of carbon. The project plans to investigate the evolution of fluid-flow systems, recovery rate, long-term injectability, and mechanical-flow behaviour. Findings are expected to provide practical information on the geomechanical viability of this green power option.Read moreRead less

At a local level, the production of alternative transport fuels has the potential to provide rural Australia with a sustainable biomass-based industry. The establishment of fast growing wood plantations to supply the needs of the new industry can assist regions of low rain-fall and high salinity to recover. Exporting advanced Australian alternative fuels technology to other countries with similar energy and environmental problems will further enhance the economic and social benefit to Australia.Read moreRead less
