WHAT IS SOLID BASED GRAVITY ENERGY STORAGE

What are the equipments for gravity energy storage

Solid Block Gravity Energy Storage ProcessA heavy solid block, such as a concrete block, is lifted to a higher elevation using a crane or a hoist and held in place.When energy is needed, the block is allowed to fall, which drives a generator to produce electricity.The block is then lifted back up to its original position, where it can be held until the next cycle.
