Gaseous hydrogen is much more dangerous than natural gas (flame speed, range of air fraction for combustion, ability to escape seals, etc., etc.) and you need three times the volume to deliver the same energy.[1] I doubt there will be much reticulated use.

- epistasis 4y agoI'm hoping we can convince gas companies to convert into district heating companies. It's still the heating business, and uses pipes and liquids. They could make heat pumps far more efficient by using ground sources of heating and cooling, and maybe even shipping process heat from one building to another. It would be a it of a shift, but it uses the same core competencies and would allow them to survive. However I don't think there's a single gas company with management with the vision, innovation, and smarts to make the switch. It would take a new generation of management, that's smarter and more forward looking. Maybe a shareholder revolt at one could cause a change in management that would pioneer this change... how much does a gas company cost?
- lstodd 4y agoDistrict heating is hell. Most ex-Soviet/Warsaw pact countries tried to move from district to direct gas, or small CCGT plants (as in one for about 10000 people) exactly for this reason: maintenance is hell and losses are enormous. And that's in high-density urban. In low-density suburbs it won't ever fly.
