Yes, it is an unsolved problem. Even adding 8h backup battery puts solar on par with nuclear: https://www.nrel.gov/docs/fy23osti/85332.pdf (nuclear's capital costs are around $4000/kW).

And seasonal storage (enough energy to last for 2-3 weeks without sun/wind) does not even have a price tag, because it simply doesn't exist.

> And foreseeable technical advances will improve that while no comparable development is on the horizon for nuclear.

Nope. Renewables have comprehensively failed in providing a viable replacement for nuclear power. There is no reasonable pathway ahead with the current technologies for renewables to replace the reliable baseline generation.

It doesn't mean that solar/wind are useless, they work great in cases where the load can be shed, and in warm climates where electricity demand is not so critical.

BESS and solar are not on par with nuclear for several reasons: (1) there is a much faster construction pathway for solar+BESS than nuclear, (2) costs of both PV solar and BESS continue to go down every year, while nuclear doesn't have the same cost curve, (3) manufacturing capacity for solar and BESS continue to rise on the exponential piece of an S-curve (meaning, a consistent multiplicative increase every year) while nuclear construction rates don't look anything like that.

There is a root cause for this: both solar PV and battery storage can be mass-produced in factories, and current nuclear tech can't. If nuclear can get onto a similar growth trajectory, we'll be cooking.
