How much does gravity energy storage cost?
South African scientists have designed a novel gravity energy storage system that uses linear electric motors to vertically move multiple solid masses to store and discharge electrical energy. They say its levelized cost of storage (LCOS) is $137.20/MWh, but with efficiency improvements, it could drop to about $100/MWh
What is gravity storage?
The concept is quite similar to a hydro-pumped energy storage scheme, which has been around earlier. But instead using water in two different containers, Heindl’s Gravity Storage uses water and rocks in just one container. Besides being the most efficient, Gravity Storage also happens to be the cheapest energy storage.
What is gravity energy storage technology?
Fig. 1. Classification of energy storage technologies. Gravity energy storage technology (GES) depends on the vertical movement of a heavy object in a gravitational field to store or release electricity.
