as new greener methods of electricity generation will result in the hydrogen itself becoming even greener, which is a much better solution.
We'd need to step up the green electrickery production somewhat to replace all the transport power with the highly inefficient cracking of water to get hydrogen. We are barely able to produce a fraction of the uk's current elec usage with its currently available renewable capability, even if we scale up and use every possible renewable resource we may jsut be able to cover our own growing elec needs. And you want to throw all of our transport fuel needs into the mix too? You'd best get working on the technology then!
