A 100MWh gravity-based energy storage system developed by Energy Vault is expected to begin construction in China in the second quarter of this year, the Swiss-American startup has claimed.
Depending on the considered scenarios and assumptions, the levelized cost of storage of GES varies between 7.5 €ct/kWh and 15 €ct/kWh, while it is between 3.8 €ct/kWh and 7.3 €ct/kWh for gravity energy storage with wire hoisting system (GESH). The LCOS of GES and GESH were then compared to other energy storage systems.
Another gravity-based energy storage scheme does use water—but stands pumped storage on its head. Quidnet Energy has adapted oil and gas drilling techniques to create "modular geomechanical storage." Energy is stored by pumping water from a surface pond under pressure into the pore spaces of underground rocks at depths …

Gravity batteries might be the answer. The idea sounds simple – when there is plenty of green energy, the batteries use the power to lift a heavy weight either high into the air or to the top of a deep shaft. Then when the power is needed, winches gradually lower the weight, and produce electricity from the movement of the cables.
