Not only does formic acid make hydrogen easier to store and transport, it's a very efficient hydrogen carrier, with 1 L (0.3 gal) of formic acid carrying 590 L (156 gal) of hydrogen.

New research shows that formic acid could be used as a safe, easy-to-transport source of hydrogen for fuel cells. Matthias Beller and his colleagues at the Leibniz Institute of Catalysis, in ...
