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.

Halt! Propose a working alternative first, we'll talk about banning later.

Electricity. It doesn't leak from cables.
Now: we need to get away from solutions that involve pressurised gas being piped or transported around the world. =)

https://en.wikipedia.org/wiki/Corona_discharge
"[...] Corona discharge from high voltage electric power transmission lines constitutes an economically significant waste of energy for utilities."
https://en.wikipedia.org/wiki/Overhead_power_line
"Transmission higher than 132 kV poses the problem of corona discharge, which causes significant power loss and interference with communication circuits. [...]"
It might be unexpected and surprising, but yes, electricity does leak from cables!

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.
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?
