Finland has inaugurated an industrial-scale sand battery this week in the southern town of Pornainen, where it'll take over heating duties from an old woodchip power plant for the municipality. It's set to reduce carbon emissions from the local heating network by as much as 70%, and is the largest…
Anywhere with municipal heating really.
I can see the middle being 600C, the edges are probably cooler.
Yes, but in milder climates one needs heating for like four or five months only. Still great to reduce emissions and whatnot, but it’d sit idle the rest of the year.
Probably. But it’d be still nice to have specs on that.
