I’ve seen some videos about redox flow batteries and a bunch of other options that appear to be suitable for the grid. I’m really looking forward to seeingt hose in action, because I believe grid energy storage is absolutelyt crucial for getting rid of coal and oil.

However, even though converting electricity to something and then back to electricity is nice, there are many cases where you can take a shortcut. Various types of industry are using fossil fuels to produce heat, so if you give them electricity, they can produce heat when they need it. That’s not the only way, because you could also reduce the number of conversions by using the energy of windy and sunny days to produce heat and store it in hot sand. Later, when the factory needs the heat but the sun isn’t shining, they can just the heat stored in the sand.
