It probably has some use for long duration storage and some industrial processes but that's about it. There will never be a hydrogen grid akin to a gas grid.

Why not? Natural gas boilers are banned from 2035. Hydrogen boilers will sure replace them. The energy density of hydrogen is much higher. Plus no carbon dioxide released when burnt.

Why not? Because it is hard to store, hard to transport, it leaks alot and will cause embrittlement to steel, so expect the maintenance of this gas grid to astronomical.

Also it takes about 3 units of electricity to produce 1 unit of hydrogen. A hydrogen boiler will take 1 unit of hydrogen and turn it into about 0.8 units of heat... It makes no economic sense.

For comparison a ASHP will use 1unit of electricity and produce between 2.5 and 3 units of heat.

I don't know how you can say that it's being ignored when there is a new research centre being built right next door to TWI who will also be involved in exploring storage solutions. Hydrogen is in some ways safer than propane because it is lighter than air and so that leaks dissipate into the atmosphere. Propane can collect in pockets on the ground.

I'm aware of the Hindenburg disaster but I know that whatever methods we settle on to store and transport hydrogen, it won't be in a balloon.

Oh well if TWI are building a research centre everything should be okay. Theyd be the last people I'd go to for advice.

I can say it because I know. The American standard for building transportation systems for hydrogen is 6 times bigger then the UK standard. Catastrophic failure due to hydrogen embrittlement and in particular in the heat affected zone and areas of stress concentration is not being sufficiently investigated.
Its not even known if standard construction techniques can be adopted for hydrogen
Fundamentals such as material qualification and laboratory testing of Industry standard materials is being ignored.

Even with all of that the skills knowledge and experience required to build pipelines to the high standards we set in this country for methame pipelines have all gone. Its a decade since we built anything of any consequence. People have retired, add IR35 into mix and the jobs will never be manned up with anything other than idiots chancers and cowboys.

Just how it is.

Which is where

My guess is nuclear and renewables.

I have asked the question before on threads on here about electric vehicles and heat pumps and not got an answer.

To me you have to explore other alternatives too that do not add carbon to the atmosphere.
