The H part of this is made by ITM Power, ticker ITM, in whom one could actually buy a stake.
They are also involved in the UK pilot of feeding hydrogen into the gas mains in a town in the northeast. The feed is 20% which is near the maximum that can be burned in a standard gas appliance.
Somewhat negative commentary here https://www.rechargenews.com/energy-tra ... -1-1045075 In a 100% hydrogen network, not only would all gas-burning appliances — boilers, cookers, ovens, etc — need to be replaced, but the grid network would need to be upgraded to handle the smaller hydrogen molecules. All metal pipes would need to be replaced with polyethylene ones — including those ones hidden in walls and under floorboards in people’s homes — while all the valves and compressors across the network would also have to be swapped out.
Personally I will invest very little in 'green energy' at the moment as I think much of the sector is a variety of solutions looking for a viable problem. ITM for instance makes electrolisers, and in static applications one has to wonder about the wisdom of using electricity to make hydrogen to burn to make heat, when one can just create the heat directly from the electricity.
And if that comment above about the gas network is true, which I haven't seen before but hydrogen is indeed very 'leaky', then the whole idea of using the existing network falls on its face.
I think for the moment I shall leave green investment to the pros, and just hang on to their coat tails as an incidental part of IT portfolios.
