Is this different in some way from natural gas? Why can't we use the existing storage and distribution infrastructure for natural gas for handling hydrogen?
Hydrogen is a much smaller molecule, so it leaks out of much smaller holes. It leeches into metals and causes hydrogen embrittlement. It is about 1/3 the energy density per volume of natural gas.
Natural gas distribution infrastructure is far leakier than you expect. It's a massive problem. We really need to get away from solutions that involve pushing gas through pipes.
