6 FAQs about [Stone energy storage]
What is stone storage and how does it work?
The idea is that when excess energy is produced by intermittent renewable sources like wind and solar, this energy is used to pump very hot air into the stone storage, where the energy in the form of heat can be stored for many days with very little loss on average.
How does the energy storage system work?
When there is a surplus of electricity from wind or solar, the energy storage system is charged. This is done by compressing heat energy from one or more storage tanks filled with cool stones to corresponding storage tanks filled with hot stones. The passage discusses the method of energy storage using GridScale's technology.
How long can heat be stored in a stone-filled tank?
The heat can be stored in the stones for many days. When there is demand for electricity again, the process reverses, so the stones in the hot tanks become colder while they become warmer in the cold tanks.
Could stone storage technology be a big advantage in the green transition?

How long can a Gridscale electricity storage system last?
A GridScale electricity storage system can cost effectively store energy for up to about a week. While lithium batteries are only cost-effective for the supply of energy for short periods of up to four hours.
How does a rock storage system work?
With this rock storage, air heated by passing it through the hot rocks, can be used create steam which can run a conventional steam turbine and create electricity OR the hot air can be used to directly heat water for district heating. On an evening walk in my community in awe of biodiversity.
