What went through your mind at this point?

Men det er vel godt at Sverige er delt op?

Luckily, storage systems make money out of this and are building out fast 😄

Danish municipalities are back to pen and paper (and that will NOT work well):

I'm not really qualified to comment, but before running with the conclusions of this study, check this thread:

My guess is Putin would like a Belarus scenario. But liking and getting are two very different things here.

But it's not really worth it to discuss individual factories, a kWh is a kWh, doesn't matter where it comes from or where it goes.
The questions are:
What's the cheapest energy in the daytime in the tropics? It's solar.
What's the cheapest energy in the tropics if you want 24/7 firming? If you have a reactor running now, it's cheaper to keep it running. If it's not built yet, it is quite likely to be undersold by the time it's done.

1) You're overestimating cost per kWh a bit, see chart. Also, these are Li ion batteries, the most performant type, overkill for stationary storage. Mass produced sodium batteries just came online. The trend in the graph will continue. I don't see why we couldn't do 20$/kWh, a factor of five.
2) There is no two-day dunkelflaute. There's daytime and nighttime. That's another factor two.
Suddenly it's looking quite realistic compared to the cost of the rest of the plant.

OK, I'll try to take one thing at a time:
1) We're talking about Africa. They don't have dark danish winters.
2) Let's aim for 1 kW/person. It could be more, depending on what kinds of production you want, but it's a simple starting point. If you have reliable sunlight every day, you then need 20 kWh/person.
3) Battery grid storage does exist, but it's just started. It's moving crazy fast, but Rome wasn't built in a day.
4) It's absolutely possible to procure 20 kWh battery per person. I think Norway must be pretty close, just with what's in their cars.
Why can't Africa have the same, and then a lot of PV?

I don't see why solar and batteries won't work for Africa?
Here in Denmark, solar lets us down during winter, but if you only need firming on a day to day basis, batteries are fine.

If only people in African countries had access to a better source of energy!
Like, it should be cheap. It should be easy to deploy with the local workforce and not require big centralized organizations. It should give a reliable output in all seasons, and preferably not depend on specific resources available to only a few nations.
If only such a thing existed!
