Sorry this is a late reply. I can see that mentioning molten salt was a bit left-field, However, it is one of the more realistic ways to store the huge amounts of power needed to fuel an economy for a couple of weeks (which you need in northern europe if you want to use solar/wind). Here’s a link about it:

I am pro nuclear, but if we are going to descend into this renewable hell, then we need to actually think about how you store terawatt-hours of power. I really think that this kind of storage might be the nearest we have to a solution. we’ll only need it once we try to turn off the gas turbines, of course. It is fascinating that so many smart people don’t see that the whole jigsaw is missing vital pieces.
Don’t pay this! You just reinforce their predatory practices. How renewals at much higher prices are allowed - no clue!
Something similar happened to a company I know - it expired and was immediately bought by domain squatters, when they found them they were told that it couldn’t be sold back because the squatter had paid $XXXX for and had big plans (I assume it was BS, just a premise to get paid - no site was ever put on the domain)
Solution: they bought the .org version and bought the .com back a year later.
