Hydrogen is going to become more commercially available with it being pushed into the steel industry. It is being trialed for direct injection into blast furnaces in order to reduce carbon emissions, and so far it has been going well. It will need more active supply to make an impact, amd that is already in the works.
Source: I work for a steel company who is trialing this currently, and hydrogen providers are stepping up their infrastructure as we speak
You're actually using the hydrogen instead of inefficiently turning it into electricity and driving electric vehicles with it, so I'm not sure why you thought this was relevant to bring up in a discussion about hydrogen fuel cell vehicles.
Completely correct observation. 70 % conversion of electricity to hydrogen 50 % loss for storage 70 % conversion back to electricity = 0.70.50.7 = 25 % efficiency. Absolutely abysmally low. Unless there is a lot of renewable in the electricity mix, it is even worse than ICE!
