Hot Rocks  - a name I've encountered before, combined  with Energy Islands 

“The market for storing electricity from renewables is huge, and we expect that Grid Scale’s combination of a long discharge cycle and low cost will attract international interest.” 

The energy islands and the wind farms with a combined capacity of 5 GW are expected to be commissioned by 2030.

The North Sea energy island will have an initial capacity of 3 GW which could potentially be further scaled up to 10 GW offshore wind. This will be an artificial island.

The Baltic Sea energy island will be established on the island of Bornholm with a capacity of 2 GW.

Following the political decision to proceed with the projects, the Danish Energy Agency has instructed the Energinet to initiate site investigations, environmental and metocean studies and analysis for grid connection for the area of investigation.

Both energy islands will export power to the mainland of Denmark and neighboring countries and are intended to serve as a hub that collects electricity from the surrounding offshore wind farms and distributes the electricity between countries via electricity grid connections.

Feel free to join me at the Energy Islands Professionals Group:
