"to productionise hydrogen in safer ways and wean us off our carbo"

Producing it safely is not the problem - getting the energy to produce it is.

Whatever way you make it needs energy - 2H2+O2 -> water +~~600kJ/mol So you need at least that and indeed a lot more to produce hydrogen gas. So >1MJ to produce about 70 litres of hydrogen gas.

Distribution and storage are also problems
