depends if they produce the H2 centrally, then you have to distribute
it, or have "micro" production e.g. at petrol stations or fleet HQs

I think they're building a factory in Sheffield to knock out the
hydroliser/compressors in shipping containers. Obviously you've then got
to beef up the electrical distribution instead of hydrogen tankers.
