Heating homes with hydrogen is neither cheap nor environmentally friendly

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.

So the article complains about people using hydrogen as a long-term energy storage solution and then at the end says people should use it as a long-sterm energy storage solution.
