Most of the supporters of hydrogen trains are the Oil & Gas lobby, a traditionally conservative group. It's another, "Technology will save us from climate change!" scheme, which will allow unabated oil extraction to continue so we can make hydrogen fuel.
If I may?
Hydrogen, green hydrogen, can be produced from water, using electricity produced from renewables, like solar amd wind.
My own country is in the process of converting a decomissioned refinery into a hydrogen plant.
It may not solve much in the short term but as an energy reserve, hydrogen can find use directly as a fuel or for running gas turbines to produce electricity in replacement of conventional gas.
Green Hydrogen from Electrolysis is extremely inefficient (<30%). Renewable energy isn't without cost or environmental impact, so we need to responsible with how we use it. Unless the grid you're pulling from is 100% renewable and has excess power that is just being wasted, that renewable energy could be used elsewhere in a more efficient manner.
Regardless, it is a start. Unless we are to stumble upon the secret of cold fusion, we need to compromise in order to make any kind of move away from fossil energy.
The project I mentioned is to be a self contained system, reliant on renewables only, hence the green classification.
