A new method for biological hydrogen storage uses parts of the natural metabolism of acetic acid bacteria to convert hydrogen and carbon dioxide into formic acid.
Additionally, the newly developed technology can be used to remove toxic carbon monoxide from hydrogen containing gas mixtures (e.g. synthesis gas) and to convert it to carbon dioxide, and consequently into formic acid.
