Replacing a gas boiler with a heat pump is "irrational"
Posted by: @jamespipe@kev-m Why? Many countries are already producing green hydrogen.
There are some small scale experiments. Heating homes directly with H2, green or otherwise isn't currently viable. The infrastructure isn't suitable and it's an extremely inefficient E2E process. Production of H2 using excess RE might be viable. But green H2 production doesn't currently lend itself to ramping up and down and the alternative is lots of storage, which we don't have and costs a lot. A combined wind/green H2 system that can deliver nuclear levels of certainty is going to be very expensive.
Maybe not quite fantasy but it's a long way from reality.

Germany appears to be working towards having green Hydrogen as a key element of their energy mix.
Below are some interesting videos and information.
