High school chemistry class? H2 is such a tiny molecule that leaks out of everything making it a nightmare to try and seal pipework, and it will permeate (and embrittle) metals, namely steel. It's idiotic to try and use it as a fuel. The money being wasted on H2 research should just go into purchasing more renewable power sources.
