The EVx energy storage tower lifts composite blocks with electric motors. Image: Energy Vault Energy Vault, maker of the EVx gravitational energy storage tower, has secured $100 million in series C funding.
How would a tower storage system work?
The storage system would work by stacking thousands of blocks in concentric rings around a central tower, which would require millimeter-precise placement of the blocks and the ability to compensate for wind and the pendulum effect caused by a heavy weight swinging at the end of a cable.
What is energy storage?
Energy storage represents a primary method for mitigating the intermittent impact of renewable energy. By dispatching stored energy to meet demand, a balance between supply and demand can be achieved. This involves storing energy during periods of reduced grid demand and releasing it during periods of increased demand .
