Re: Not as green as 25kv overhead
>Natural gas is hydrogen bonded to carbon
Obvious solution is to combine the hydrogen with carbon = green carbon capture tech
Then distribute the resulting methane safely by pipeline into tanks on the train = simple existing technology
Use solar, wind or reliable nuclear electricity sent over low-loss 25KV overhead lines to split the methane into carbon and hydrogen. the hydrogen can then be fed to the fuel cell.
A future Britain could then develop some technology to allow trains to be powered by the waste carbon byproduct
