But Schmidt''s calculation of the lifetime cost per megawatt-hour for lithium-ion batteries, $367, is more than twice as much. Flow batteries, a promising grid-scale technology that stores charge in large tanks of liquid electrolyte, come in at $274 per megawatt-hour. Other gravity-based storage companies have their own twists on the technology.

Pumped hydro and Gravity Power both use hydraulic power and a liquid pump or turbine to move water or produce electricity. The difference is that the liquid medium in pumped hydro is the energy storage medium. The pump or turbine sits between the two water reservoirs and is used to move the water up or down the hill.
Specific gravity is a crucial aspect of battery health, as it indicates the state of charge and the overall condition of the battery. Specific gravity readings are taken to determine the concentration of sulfuric acid in the battery''s electrolyte. The specific gravity of a lead-acid battery should be between 1.265 and 1.299 when fully charged,
Unlike gravity batteries, pumped hydro is an established technology that provides more than 90% of the world''s high-capacity energy storage, according to the International Hydropower Association. But facilities are expensive to build and restricted by geography: the technology requires hills and access to water .

Yet gravity-based storage has some distinct advantages, says Oliver Schmidt, a clean energy consultant and visiting researcher at Imperial College London. Lithium-ion batteries, the technology of choice for utility-scale energy storage, can only charge and discharge so many times before losing capacity—usually within a few years.
A number of companies have invested considerably in gravity batteries, and boast impressive figures regarding energy efficiency and power storage. Scottish start-up Gravtricity claims to be able to power 63,000 homes through an hour of operation of its 20MW facility, while GravitySoilBatteries aims to provide up to 30,000kWh of storage at a
Simple, clever and durable: The technical concept of Gravity Storage uses the gravitational power of a huge mass of rock. It will store electricity of large capacity between 0,5 and 10 GWh and will close the gap between renewable energy production and 24/7 supply with zero carbon electricity: cost-efficient, at giga-scale, environmentally friendly.
