>When probed on how to address intermittency, many wind and solar advocates propose things like hydrogen storage, giant flywheels, compressed air, or other solutions that are currently in the prototyping stage and have yet to actually be deployed to a grid and demonstrate viability. Cryogenic energy storage ("liquid air") plants have been deployed - a 15 MWh (5 MW peak) grid-scale demonstration plant has been operating in Greater Manchester near where I live since 2018, and there's a permanent 250 MWh (50 MW peak) plant under construction on the opposite side of the city region. Granted that peak energy usage in the UK today was around 42 GW, so it's a small fraction (OTOO a tenth of a percent at peak) of what's needed, but... it's coming. I fully agree with you, though, that nuclear is needed. Renewables + storage can't be the complete answer. I'm a wind, solar and nuclear advocate.
