There hasn’t been a lot of energy talk here on the Globalhood blog. Let’s change all that and kick things off with a recent article from Chuck Squatriglia at Wired about bacterially developed hydrogen.
Researchers at Penn State University say they’ve developed a way to use bacteria to extract hydrogen from almost any biodegradable organic substance, from grass clippings to wastewater.
Hydrogen is often touted as a virtually limitless source of clean energy, but its ecological benefits have been minimal because it is often produced using natural gas in a process that releases carbon dioxide — a problem the new method seems to solve.
The discovery, published Monday in Proceedings of the National Academy of Sciences, holds great promise for advancing hydrogen as a viable sustainable fuel because, the researchers say, it uses existing technology and can be put to use immediately.
“It’s crossed the line from a science-fair project to feasible technology,” said Bruce Logan, a professor of environmental engineering who led the research. “You can do it from any renewable organic matter.”
