>I've tried to summarise what I was able to learn about it in this article :)

I literally wrote that I wrote the article myself.... 🙈

Yes, I get that. I'm an energy/mechanical engineer, and working as management consultant for the energy industry. It's a hard case. But the problem of renewables right now really is their intermittency... Solar PV has a load factor of 11-16 % over the course of the year, but in winter weeks you can easily get load factors of 1 %.

Space-based solar power can achieve close to 100 % load factor and delivers equally in summer and winter. From the value side, it provides much more than wind and solar do right now. But the cost side, of course, is also much more intensive. However, it appears to become economically feasible with launch costs decreasing further and further. If not as baseload than at least as peak capacity.

ESA is currently running two studies (results expected in the next months) which are expected to show that the cost of such a system could actually be further reduced if we were to use materials from the Moon.
