I mean the UK has 6% of its energy over the year come from solar, and 30% from wind, and installations are only accelerating, so this amount of installed solar is far from unrealistic.

Installing storage approximately doubles the LCOE of solar energy, so this is also feasible from a cost point of view as we get rid of dispatchable gas turbines.

Basically if we solve storage, we can get rid of nuclear, but not before.

I am not saying we should get rid of nuclear. I am saying we should keep some nuclear, also once we have got less gas and more storage. Does this resolve some things in this discussion for you?

You need H2 only after solar + EVs provides more than 24 hours of needed energy in an area. Although H2 does save on transmission costs for medium to long distance. One of the remarkable aspects of BYD Dolphin, now under $9000 for 32kwh battery is that the battery value alone is $260/kwh capacity, and if you never drove it, but sold electricity 2.6c/kwh higher at night than you pay at day, then you pay for the car in its entirety. Just batteries can be sold under $100/kwh in China, and you could make 200% ROI from 3c/kwh price differential. EVs and batteries can be paid by private sector instead of utility investment markup model.

H2 technologies are advancing, including storage and pipes. Electrical transmission is more than 10x more expensive than transmitting gas/H2, and saves money on that end relative to efficiency loss. Surplus solar with input cost at 2c/kwh or less achieves under $2/kg H2 target which is equivalent driving distance to $1/gallon gasoline, and 10c/kwh electric only value delivered energy, and 6c/kwh combined heat and electricity value.

Las Vegas has already achieved 97% storage supply for its needs - a city that barely sleeps at night.

Again, where is your evidence that it is not going to improve across the board, and will all fail?

"It's not all happening right now," is not even close to a convincing answer. If that was the reason to exclude any technology, there'd be none.

And it's an especially ironic answer given that it takes up to 20 years to commission a nuclear power plant. And they are down for scheduled maintenance for up to a month a year, etc.

OP sepcifically mentioned EVs. This sector is deflationary even in US, where better value/performance cars cost less every year. More dramatic deflation in less corrupt countries. Australia home solar costs under 1/3rd of US due to different politico-social corruption levels.

EVs and home solar are a great match that permits going offgrid at substantially lower cost if an EV is parked at home during day. That same dynamic allows a society/community to power itself through solar+batteries, and EVs parked at work. It's not a question of look at our corrupt obstructionist oligarchical monopoly state of societies for examples of lack of economic success as proof that it will forever be impossible.
