Technical ReportBiochar and bioenergy production for climate change mitigationCategory: Biochar - Documnet Type: Technical ReportThe world will increasingly depend on renewable energy with low or zero net greenhouse gas (GHG) emissions. This paper explores how science and the economic ‘rules of the game’ might realize the potential for the pyrolysis co-production of biochar and bio-oil to mitigate net GHG emissions while achieving other economic and environmental benefits....

Bio-Char Soil Management on Highly Weathered Soils in the Humid TropicsCategory: Biochar - Documnet Type: Technical ReportMaintaining an appropriate level of soil organic matter and biological cycling of nutrients is crucial to the success of any soil management in the humid tropics. Cover crops, mulches, compost, or manure additions have been used successfully, supplying nutrients to crops, supporting rapid nutrient cycling through microbial biomass, and helping to retain applied mineral fertilizers better....

Energy and Greenhouse Impacts of Biofuels: A Framework for AnalysisCategory: - Documnet Type: Technical ReportIn this paper, we review some of the basic energy balance and climate change impact issues associated with biofuels. For both the basic energy and greenhouse gas balances of producing and using a range of fuels, and for the increasingly debated and important issues of nongreenhouse gas impacts such as land, fertilizer,...

Alcohol Fuels from Biomass – Assessment of Production TechnologiesCategory: - Documnet Type: Technical ReportThe purpose of this study is to consolidate and document the progress to date and development status of biomass-to-alcohol (bioalcohol) production technologies, and to help guide continued development activities in the Western region and elsewhere. Specific objectives outlined for the study are to: ... More»Author: Dennis Schuetzle, Gregory Tamblyn and Frederick Tornatore - submitted on Mon, 11/03/2008 - 18:38. EPRI Solar Thermal Electric Technology UpdateCategory: Solar Energy - Documnet Type: Technical ReportAfter years of relative inactivity, the solar thermal electric (STE) industry is experiencing renewed activity and investment. The shift is partly due to new interest in large-scale centralized electricity generation, for which STE is well suited and offers the lowest cost for solar-specific renewable portfolio standards....

Biofuels at What Cost: Government Support for Ethanol and Biodiesel in the United StatesCategory: Policy Incentives - Documnet Type: Technical ReportGovernment subsidies-at both the state and federal levels-have long played an important role in the expansion of the biofuels industry in the United States. Liquid biofuels have been subsidized largely on the premise that they are domestic substitutes for imported oil, they reduce greenhouse gas (GHG) emissions, and they encourage rural development....
