Efficient hydrogen producing – new method found

Bacteria and added electricity produce large amounts of hydrogenResearchers at Penn State University have produced hydrogen gas at efficiencies not found before. Tweaking an existing method that previously produced poor rates and yields, the scientists found they could produce nearly 300% the energy used to kickstart the reaction.

Electron-generating microbes produce an electric current that is run through a fuel cell containing biological matter. By adding an additional jolt of electricity at the cathode, the bacteria breaks down the organic matter into hydrogen, without releasing much in the way of greenhouse gases. Whilst this is an early result needing mass study and production, it’s a very promising discovery towards clean fuel.
