It's only explosive when mixed with air in confined places, as is gasoline, LPG, CNG, steel, wood and flour. Unlike most others, confinement is a requirement, otherwise it escapes too quickly. See [1] for comparison.

For these reasons I suggest we should produce and store methane, though hydrogen issues aren't a showstopper and hydrogen fuel cells are more efficient.

- makomk 5y agoHydrogen is highly explosive at almost all concentrations in air, extremely easy to ignite, and leaks through most widely-used materials. It's much worse in all these aspects than common fuels like gasoline, LPG, natural gas, etc.
- labawi 5y agoWhile the claims are (likely) technically true, if you are trying to insinuate it is less safe, then that is a false conclusion. As an example, many garages ban LPG cars, but don't care about CNG, AFAICT, because LPG can pool around on the bottom, but methane is light and easily escapes. Hydrogen is even lighter and harder to contain. The link [1] has compelling arguments.
