Abstract. Large-scale energy storage technology is crucial to maintaining a high-proportion renewable energy power system stability and addressing the energy crisis and environmental problems. Solid gravity energy storage technology (SGES) is a promising mechanical energy storage technology suitable for large-scale applications.

This concept is known as gravity storage, as it stores electricity in the form of gravitational potential energy. This storage option provides better operating characteristics and economically sounds solution over conventional pumped hydro storage, and can be placed almost anywhere electricity storage is needed.

Compared with the gravity storage power plant using a single giant weight, the modular-gravity energy storage (M-GES) power plant has better flexibility in operation and manufacturing. Given the promising application of M-GES and the lack of control research, this paper investigates the control technologies of M-GES power plants.

As a branch of gravity energy storage, the M-GES power plant is a promising large-scale physical energy storage technology and is one of the alternatives to the widely used pumped storage technology. In response to the capacity limitation problem of M-GES power plants in large-scale scenarios due to the excessive number of units,

Power: 5 MW Energy: 35 MWh. Energy Vault places bricks, one top of another, to store potential energy and lowers bricks back toward ground, to release energy. Fully automated 6-arm crane operated by software, provides up to 5 MW of electricity without interruption. Can charge and discharge between 4 and 50 hours depending on product and

The Energy Vault storage center co-located with a grid-scale solar array. Image: Energy Vault . The company said its technology can economically serve both higher power/shorter duration applications with ancillary services from 2 to 4 hours and can also scale to serve longer-duration requirements from 5 to 24 hours or more.

The company built a structure consisting of hollow towers. The facility utilizes excess solar power in the system to pull up the weight, creating potential energy. When needed, the blocks are dropped and electric motors generate electricity. The technology is not much different from pumped storage hydropower. First gravity
