Sharing the risks and costs of biomass crops

September 4, 2013 4:09 pm | News | Comments

Farmers who grow corn and soybeans can take advantage of government price support programs and crop insurance, but similar programs are not available for those who grow biomass crops. A new study recommends a framework for contracts between growers and biorefineries to help spell out expectations and designate who will assume the risks and costs.

Policy issues plague hydropower as wind power backup

June 27, 2013 2:11 pm | by A'ndrea Elyse Messer, Penn State University | News | Comments

Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to recent research. Hydroelectric dams are controlled by guide curves that account for drinking water and droughts. They cannot simply release water to meet some electricity demand or hold back water when electricity is in low demand.

Power for seaports may be the next job for hydrogen fuel cells

June 27, 2013 8:01 am | News | Comments

Hydrogen fuel cells are already powering mobile lighting systems, forklifts, emergency backup systems and light-duty trucks, among other applications. Now, researchers at Sandia National Laboratories have found that hydrogen fuel cells may be both technically feasible and commercially attractive as a clean, quiet and efficient power source for ships at berth, replacing on-board diesel generators.

High-octane bacteria could ease pain at the pump

June 25, 2013 1:28 pm | News | Comments

By rerouting the metabolic pathway that makes fatty acids in E. coli bacteria, researchers at Harvard University have devised a new way to produce a gasoline-like biofuel. According to the scientists, who are tweaking metabolic pathways in bacteria, new lines of engineered bacteria can tailor-make key precursors of high-octane biofuels that could one day replace gasoline.

Solar plane to help ground energy use

June 19, 2013 1:01 am | by Seth Borenstein, AP Science Writer | News | Comments

When it's in flight, there's no roar of engines. It's strangely quiet. And as it crisscrosses the U.S., the spindly plane doesn't use a drop of fuel. Ernest Moniz, who heads the U.S. Department of Energy, praised the efficiency of the Solar Impulse plane at a news conference Monday in Washington, where the plane landed early Sunday morning. He said the solar-powered aircraft highlighted a cleaner energy future for the nation.

Study: Nation equipped to grow serious amounts of pond scum for fuel

May 22, 2013 9:02 am | by Tom Rickey, PNNL | News | Comments

A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year in the United States, one-twelfth of the country's yearly needs. The findings come from an in-depth look at the water resources that would be needed to grow significant amounts of algae in large, specially built shallow ponds.

Solar industry pushes for more use in Ga.

May 21, 2013 1:25 pm | by RAY HENRY - Associated Press - Associated Press | News | Comments

The solar industry in Georgia is pushing a power monopoly to expand its use of solar energy as it plans to meet the state's electricity needs over the next two decades. State utility regulators heard testimony Tuesday on the energy plans from Southern Co. subsidiary Georgia Power, which must submit new plans every three years.
