A new industrial-scale 'sand battery' has been announced for Finland, which packs 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be about 10 times bigger than a pilot plant that’s been running since 2022.

    How does it hold warmth months at a time? Seems a little hard to believe, but if it’s true, that’d be great. I hope this isn’t something that’s spoken of once and never again.
