Supercritical water could lead to biomass-to-fuel conversion on a large scale
New catalyst for hydrogen fuel cells resists CO contamination
New hydrogen production method could reduce need for fossil fuels
Next generation of biofuels is still years away
The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply, after years of broken promises and hype promoting a next-generation fuel source cleaner ...
Yeast uses CO2 to boost bioethanol production
Introducing four genes from bacteria and spinach has enabled researchers at the Delft University of Technology to improve the production of bioethanol with yeast by using carbon dioxide. Their findings were ...
Transportation fuels from woody biomass promising way to reduce emissions
(Phys.org) —Two processes that turn woody biomass into transportation fuels have the potential to exceed current Environmental Protection Agency requirements for renewable fuels, according to research published ...
Cost-saving measure to upgrade ethanol to butanol—a better alternative to gasoline
Scientists today reported a discovery that could speed an emerging effort to replace ethanol in gasoline with a substantially better fuel additive called butanol, which some experts regard as "the gasoline of the future." ...
Photovoltaics beat biofuels at converting sun's energy to miles driven
In 2005, President George W. Bush and American corn farmers saw corn ethanol as a promising fossil fuel substitute that would reduce both American dependence on foreign oil and greenhouse gas emissions. Accordingly, the 2005 ...
Bioengineered marine algae expands environments where biofuels can be produced
(Phys.org)—Biologists at UC San Diego have demonstrated for the first time that marine algae can be just as capable as fresh water algae in producing biofuels.
Mixing processes could increase the impact of biofuel spills on aquatic environments
Ethanol, a component of biofuel made from plants such as corn, is blended with gas in many parts of the country, but has significantly different fluid properties than pure gasoline. A group of researchers from the University ...
Fuel cells operating directly on ethanol
(Phys.org) -- Researchers at the Center for Energy Research at UC San Diego recently demonstrated the best performance for solid oxide fuel cells (SOFCs) operating directly on ethanol without external reformation. ...
US looks ahead after ethanol subsidy expires
After a series of bitter political fights, the US Congress allowed a subsidy for ethanol fuel to expire at the end of 2011, ending a program harshly criticized by environmentalists and others.
Study questions cost-effectiveness of biofuels and their ability to cut fossil fuel use
A new study by economists at Oregon State University questions the cost-effectiveness of biofuels and says they would barely reduce fossil fuel use and would likely increase greenhouse gas emissions.
Second-generation ethanol processing cost prohibitive: study
Costs for second-generation ethanol processing, which will ease the stress on corn and sugarcane, are unlikely to be competitive until 2020, according to a unique Queen's University study.
