I read an article recently about an unusual increase of H2 in the atmosphere. Scientist as yet are unable to account for all the sources of this greenhouse contributor gas.
Might I suggest aluminum as a possible suspect? Al loves Oxygen and any time bare metallic Al comes into contact with water H2 becomes a high probability, especially when salts and minerals are present to act as catalysts. A beverage can in ocean water will dissolve into Al2 O3 and 3- hydrogen 2. That's a good amount of gas don't you think?
