Sorry, you have succombed to what is a very widespread delusion, and a very dangerous one. For partially de-industrialised economies (such as in Europe and the US), it may appear that power and transport represent the bulk of energy use but this isn't even true itself. Most energy is used in industry, followed by heavy transport such as trucks, aviation and shipping.

Passenger vehicles and residential power use represent what is a tiny proportion of overall energy - cars represent 45% of all transport, and only 25% of all oil including feedstocks.

This is really not much.

We are being sold a lie about electrification, led by cynical institutions such as the IEA and IRENA who (lazily) allow us to believe that our oil dependency is not that bad, and cursory efforts (as you describe) will have a huge effect. They won't.

Having written a book on this, I have to start informing people: the conspiracy that hydrogen doesn't work, is too technologically difficult, or too expensive to produce - is precisely that. It is a narrative to maintain fossil energy & it's (government-supported) revenue to those involved throughout the value chain, indefinitely.

For industry, heavy transport, gas turbines (equal to today's renewables output if not a lot more), seasonal heating, balancing VRE intermittency etc - there is only one option. Batteries are not going to work in the vast majority of use cases.

If people don't recognise it's hydrogen, it may be too late.
