Finnish researchers have installed the world's first fully working "sand battery" which can store green power for months at a time.

The developers say this could solve the problem of year-round supply, a major issue for green energy.

Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind.

The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.

This could be a big step forward.

If this can scale economically, then it sounds like sand would be much easier to acquire and keep a supply chain of than lithium, cobalt, etc.

I agree Matt. This could be a game changer. There are so many great ideas and new technology being developed and the sooner they can scale up or come on stream the better.
