Hydrogen can be safely stored without using high pressures. For example: "Hydrides chosen for storage applications provide low reactivity (high safety) and high hydrogen storage densities." https://en.wikipedia.org/wiki/Hydrogen_storage#Chemical_storage https://en.wikipedia.org/wiki/Hydrogen_storage#Chemical_stor.... It almost seems like Elon doesn't like fuel cells because of his battery investments.
