Nuclear, coal-fired electrical plants vulnerable to climate change

June 4, 2012 7:03 am | News | Comments

Warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants. A study by European and University of Washington scientists projects that in the next 50 years warmer water and low flows will lead to more such power disruptions.

Grid realities cancel out some of wind power's carbon savings

May 30, 2012 7:08 am | News | Comments

Wind energy lowers carbon emissions, but adding turbines to the current grid system does not eliminate emissions proportionally, according to a report by researchers at Argonne National Laboratory. To test how wind energy affects carbon dioxide emissions, Argonne scientists modeled the Illinois electric grid and tested how more wind power would affect the system.

Sandia technology used in Fukushima cleanup

May 29, 2012 4:34 am | News | Comments

A Sandia National Laboratories technology has been used to remove radioactive material from more than 43 million gallons of contaminated wastewater at Japan's damaged Fukushima Daiichi nuclear power plant. Sandia researchers had worked around the clock following the March 2011 disaster to show the technology worked in seawater, which was pumped in to cool the plant's towers.

Physicists set new record for graphene solar cell efficiency

'Negative leakage' could be key to reducing carbon emissions

May 24, 2012 6:54 am | News | Comments

The unilateral efforts of a single country or region to reduce the emissions of greenhouse gases could reduce exports, increase imports and lead to higher emissions elsewhere—what economists call "leakage." Unilateral efforts could, however, work better if other sources of energy were used as substitutes, thereby creating "negative leakage," according to research by University of Illinois energy policy experts.

New carbon dioxide-removing catalyst can take the heat

May 24, 2012 4:13 am | News | Comments

The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.
