Heating homes with hydrogen is neither cheap nor environmentally friendly

• sp332 4y ago
  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.

  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.

    > Is it possible to retrofit these to burn H2 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.
