    The thing about hydrogen is that it is very reactive and wants to bond with something, anything. And if there is a single oxygen atom and a single hydrogen atom, they will combine into a hydroxyl (OH-) and then bond to either nitrogen or carbon.

Good point, but I'd imagine that the low mixing ratio of H2 makes it difficult to actually encounter O2 or anything else that it can readily bond to.

Trees, finding a way to convert it into other solids, and other novel ideas are the best bet. Whatever keeps it on the surface/in the ground. This won't solve our climate issues but the idea of vapor deposition of atmospheric carbon to create nanofibers is immensely cool.
