While studying chemistry in school, the test for hydrogen was a lighted splint held at the top of a test tube. It went with an audible 'pop' as the hydrogen exploded. The early blimps were filled with hydrogen and exploded spectacularly. That's why they changed to helium, which is inert. I hope the technology associated with hydrogen as a domestic and motor fuel is very advanced.
Yes, the industry my Dh worked in used hydrogen as a test for leaks. It’s because the molecules are smaller and will leak out of the tiniest of holes. Hydrogen also has to be manufactured, which uses electrify in itself. It’s only green if the process uses energy from reusable sources, which isn’t always possible.
My own ICE car is less than three years old. It’s very fuel-efficient compared to cars I’ve had in the past and if I sold it to go electric, someone else would be driving round in it, so I don’t see the point in ditching it. We also travel long distances and until the charging network has improved electric won’t be an option for us.
