No, it's different with hydrogen. If you want green hydrogen, you'll waste at least 50% of energy. Then there are storage and flammability etc. We have everything we need for using hydrogen today, but somehow it is not used besides minor experiments.

Yeah, but does energy waste matter if the other option is that you turn wind or solar input off? It should not run during high peak, of course, but if there is more energy in the grid than it uses? Turn it into hydrogen.

And storage, strangely that safety topic never gets raised with nuclear. If we can build safe nuclear, we can build safe hydrogen storage.

We can safely store nuclear waste. What do you think happens to all the radioactive waste produced by hospitals ?

Shoved into tanks or old mines and hope nothing happens?

True, if we have huge surplus of renewables, then the cost doesn't matter that much.

As per storage. Nuclear is far less problematic to handle in many aspects. Hydrogen is notoriously hard to store and if we go at scale, there would be massive amounts of hydrogen stored everywhere. A tiny spark away of a huge bomb.

If we can build safe nuclear, we can build safe hydrogen storage.

They're facing entirely different problems.
