We used gaseous hydrogen in a process at the GM plant where I worked in the 1970's. It was nearly impossible to maintain the supply system completely free of small leaks. Hydrogen will leak thru sub-microscopic imperfections to pipe/fittings/solder joints that no other gas can pass.
The H2 system was in fact so dangerous GM's fire insurance company required ALL hydrogen distribution piping/valving be located outside on the roof. Only the shortest possible vertical drop to the point of use inside was permitted. Even then the system suffered occasional leaks/fires - also several small explosions - from leaking H2 gas.
Bottom line: High cost aside, bulk hydrogen is simply TOO DANGEROUS to be entrusted to the general motoring public!
