Finland is leading the race to decarbonise industrial heat emissions, using sand to produce fossil-free steam.

It’s a thermal battery to capture renewable peak output.
The headline is confusing.
Oh that’s clever. I hope it lives up to the claimed cost savings, because if it does it’s much more likely to see rapid adoption
This stored heat can be used in industrial processes regardless of real-time electricity availability.
If this scales and becomes affordable this can really have a big impact.
Would a solar collector do a more efficient job of heating this sand?
Of course you could use that source, but the topic here is not about the source of electrical energy. It is about storage and constant availability.
