Fantastic if it pans out - Hydrogen generation

Curious report -- to be taken with a grain of salt as many of these "initial findings" turn out to be bad lab work or wishful thinking but still; from Yahoo/AFP:

New technique creates cheap, abundant hydrogen: report
US researchers have developed a method of producing hydrogen gas from biodegradable organic material, potentially providing an abundant source of this clean-burning fuel, according to a study released Monday.

The technology offers a way to cheaply and efficiently generate hydrogen gas from readily available and renewable biomass such as cellulose or glucose, and could be used for powering vehicles, making fertilizer and treating drinking water.

Numerous public transportation systems are moving toward hydrogen-powered engines as an alternative to gasoline, but most hydrogen today is generated from nonrenewable fossil fuels such as natural gas.

The method used by engineers at Pennsylvania State University however combines electron-generating bacteria and a small electrical charge in a microbial fuel cell to produce hydrogen gas.

Microbial fuel cells work through the action of bacteria which can pass electrons to an anode. The electrons flow from the anode through a wire to the cathode producing an electric current. In the process, the bacteria consume organic matter in the biomass material.

An external jolt of electricity helps generate hydrogen gas at the cathode.

So the heavy lifting here is done by bacteria, not by electricity. The electricity is just being used to extract the H2. Still:

"This process produces 288 percent more energy in hydrogen than the electrical energy that is added in the process," said Bruce Logan, a professor of environmental engineering at Penn State.

If this is able to scale up to industrial size, it will be a great source of hydrogen. Wonder how much more efficient it is than the current methane reformation process.
