No, turbo-alternators 'burning' hydrogen do exist. And green hydrogen (produced by renewables) is cheaper than pink hydrogen (produced by a nuclear reactor) because the total cost of renewables' electricity is lower than nuclear's.
I don’t see the connection with my comment but hydrogen is irrelevant and contributes less than a rounding error to global electricity generation. The technical components for a hydrogen based energy market do exist but are simply unviable financially. Nuclear also struggles to compete on the basis of price in competitive markets but is a genuinely low-carbon source of electricity. You could argue (I personally would not) that the higher cost of nuclear can be justified on this basis but the fact that hydrogen is an extremely potent greenhouse gas and is prone to leakage means it doesn’t even have that going for it.
