Massive underwater spheres with volumes reaching 12,000 cubic meters are about to be deployed across the United States through an innovative energy storage deployment. The StEnSea (Stored Energy in the Sea) project includes these spheres, modernizing the methods for sustaining and directing energy storage. These gigantic structures hide what exactly they contain and function as a system.
The StEnSea project: A breakthrough in energy storage
Fraunhofer Institute created the StEnSea project to store energy within the ocean depths. Underwater spheres use natural deep-sea pressure to operate an innovative method for efficient energy storage. Renewable energy technology sees a significant step forward through this innovative project.
How the StEnSea system works
The StEnSea system applies pressure from deep ocean water as an energy storage technology. Water is pumped out from spheres when there is excess energy to leave a…
