Cellulosic ethanol using gasification-fermentation.
April 1, 2008... The push for the United States to produce more biofuels was reinforced by the recent amendment to the 2005 Renewable Fuels Standard, setting a new target of 136 billion L (36 billion gal) by 2022. Cellulosic biofuels will play a major role in...

Rethinking thermochemical conversion of biomass into biofuel.
April 1, 2008... All fossil fuels found in nature--petroleum, natural gas, and coal, based on biogenic hypothesis--are formed through processes of thermochemical conversion (TCC) from biomass buried beneath the ground and subjected to millions of years of high...

Biomass feedstocks: opportunities to increase biofuels.(ENERGY ISSUES Series)
April 1, 2008... With increasing concerns over dwindling reserves and unstable supplies of petroleum coupled with climate change caused by the burning of fossil fuels, the search is on for cleaner energy. Biomass is a solar energy resource with the potential to...

Biofuel feedstocks: the risk of future invasions.
April 1, 2008... To reduce greenhouse gas emissions, expand domestic energy production, and maintain economic growth, public and private investments are being used to pursue dedicated feedstock crops for biofuel production. A variety of plant species, including...

Convergence of agriculture and energy: producing cellulosic biomass for biofuels.
April 1, 2008... Current biofuel production in the United States relies primarily on corn grain conversion to ethanol, and in 2007 approximately 26 billion L (7 billion gal) of ethanol were produced. It is estimated that an additional 30 to 34 billion L (8 to 9...
