video China commissions the world's first commercial gravity battery.

*"The principle of operation of a gravitational battery is much simpler than lithium-ion batteries. Basically, it's just a system of cranes that raise and lower concrete blocks.

The design include hoists that lift 30-ton composite blocks using an electric motor. The raised blocks are stacked on top of each other, which creates potential energy. At the moment when the consumer needs energy, the blocks fall under the influence of gravity, and the energy released in this process is collected and sent to where it required. The plant is capable of storing up to 100 MWh of energy and delivering 25 MW of power."*

Greatly inefficient. Overly complex & expensive

It seems like a few countries have adopted the idea, so perhaps they have figured it out or improved it.

Not this implementation. Pumped water or rocks… this is a dumb way to do it
