Does this address the various costs of replacing the existing heating systems which run on gas in some form? Is it possible to retrofit these to burn H2 - if so, it would be far less of an impact that ripping them all out to replace them with heat pumps. And, of course, you need environment-friendly refrigerant in said heat pumps.

Yes and no. Yes in theory. But hydrogen burns much hotter, has a higher flame speed (spark -> boom!, not woosh!), and burns in a much greater range of concentrations in air, so leaks are...dangerous. Hydrogen is also very good at leaking.

I wouldn't have it near my house.

Edit: insulate and triple-glaze. Then you have a much smaller problem to solve, for both heating and cooling.

> Yes and no.

They're trying out this exact thing in the Netherlands right now. Appears to be technically feasible.
