Waste not, want not

Bacteria-driven cell produces hydrogen for fuel while cleaning wastewater

By harnessing the efforts of billions of bacteria, researchers have engineered a bio-filtration system that produces hydrogen gas while cleaning wastewater gas that could potentially fuel other machines. Up to 100 percent more efficient at producing hydrogen than similar bio-filtration systems, the new device has the added benefit of being able to digest human or animal waste, plant material or just about any organic matter.

Hong Liu and Bruce Logan of Penn State University and Stephen Grot of Ion Power, Inc. of New Castle, Del. announced their findings online April 22, 2005, in the journal Environmental Science and Technology.

This research was supported by NSF Award #0401885:
Improving Power Generation in Microbial Fuel Cells http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=0401885

Additional Award information
The recent innovation builds upon an NSF Small Grant for Exploratory Research (SGER). For 15 years, NSF has made a small number of SGER grants--each for 1 to 2 years duration and for amounts up to $200,000--that address especially novel, or urgent, research ideas. Logan credits his SGER award with providing a critical spark that helped drive his microbial fuel-cell research.

The SGER research generated an earlier NSF press release, and an animation of the bio-filtration device. Both can be found at: http://www.nsf.gov/news/news_summ.jsp?cntn_id=100337

NSF Award #0331824:
SGER: Determination of the Potential for Direct Generation of Electricity from Wastewater Using a Microbial Fuel Cell http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=0331824

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering, with an annual budget of nearly $5.47 billion. NSF funds reach all 50 states through grants to nearly 2,000 universities and institutions. Each year, NSF receives about 40,000 competitive requests for funding, and makes about 11,000 new funding awards. The NSF also awards over $200 million in professional and service contracts yearly.
