Storage of energy in the dimensions required for weeks with almost no wind is an unsolved problem. Right now, we can't store enough to make it through a single night without using fossil fuels. Most countries don't even have the capacity to store the energy for a single hour.

As we can store fossil fuels for weeks of demand, we can store the required energy in chemical form, no? Germany has huge natural gas storage, for ezample.

If you mean hydrogen, this video explains the issues better than I can: https://www.youtube.com/watch?v=Zklo4Z1SqkE

Doesn't need to be hydrogen - plenty of possible substances that could be used as storage (might not even need to be gaseous for some applications).

Geothermal and storage is worth investing in, investing in nuclear is not. NPPs are simply too expensive and you won't find investors unless you heavily subsidize it with tax money. Only compnies willing to invest in NPPs are those with virtually free money: the handful of AI big tech giants.

How can you be sure of that before even having a practical and proven solution for the required scale of storage?

We have proven solutions.

We're building the factories to make them as fast as we can find investors with money to spend on them, because they're already cheaper than fossil fuels which are themselves cheaper than nuclear.
