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.
