Replacing a gas boiler with a heat pump is "irrational"

Mike Patrick · 2023-03-23T10:51:22Z

I just came across this reportwhich is critical of the financial case for heat pumps. It's from an industry organisation(Energy & Utilities Alliance) I'd not heard of before which has a raft of papers on heating issues. I don't think they are a lobby group with a particular agenda (eg pro fossil fuels) so their points seem valid - as does their observation that the cons, as well as the pros, of heat pumps don't get proper coverage in the overall campaign to persuade the public to junk their gas boilers.

It seems to me that ‘Blue Hydrogen’ is a disaster in the offing and will do litle or nothing towards improving matters.

And green hydrogen?

Fantasy for now.

@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.
