"Green Gravity''s energy storage technology represents a breakthrough in the search for economic long-duration storage of renewable energy," he said.
In simple terms a gravity energy storage device uses an electric lifting system to raise one or more weights a vertical distance thereby transferring electrical energy to be stored as gravitational potential energy.
Gravity energy storage systems, using weights lifted and lowered by electric winches to store energy, have great potential to deliver valuable energy storage services to enable this transformation.
