This 43 minute YouTube video is about solving renewable energy storage. It is mostly in Dutch with English subtitles.
This is a very innovative pilot plant that uses basalt rock to store high heat. After the 30 minute point they interview the guy who explains that the Siemens Gamesa system they developed can replace the coal burning power plant, using most of the plant’s original equipment like turbines and generators.
I think this is really important because basalt rock is found everywhere and it’s low tech, it requires very little other than rocks, steel pipes and heat. The rocks can store heat during the summer days and the heat can be used in the winter. The storage system is simple and can run for decades.
