RE: Prime Minister and Chancellor backing plans for new nuclear in Wales27 Sep 2021 18:07
IMO nuclear (an energy source) doesn't compete with H (an energy storage vector) instead it complements it. H created using nuclear powered electrolysis would be the vector to transfer energy to heavy goods vehicles, ships, various aircraft, etc, within which fuel cells will convert the H into electricity to power their electric motors. Trains however will continue to get their nuclear generated energy directly from the third rail.
