Solid gravity energy storage technology (SGES) is a promising mechanical energy storage technology suitable for large-scale applications. However, no systematic summary of this technology research and application progress has been seen. Therefore, the basic concept of SGES and conducted a bibliometric study between 2010 and 2021 is

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.

The plant has a speed of 0.5 m/s and a power capacity of 30 MW. The lifetime of the power generation system is 20 years. The UGES energy storage system assumes 40,000,000 tons of sand with an average generation head of 1000 m. The plant''s storage capacity is 98 GWh, and the energy storage investment costs costs.

Indeed, this is the case for all energy storage devices – batteries, pumped hydro and so on – as there is always some loss of energy as it is converted between forms, according to Green Gravity Founder and CEO, Mark Swinnerton. "Energy storage technologies can see efficiency levels of 50–90% depending on their nature," says

Solid gravity energy storage technology has excellent potential for development because of its large energy storage capacity, is hardly restricted by geographical conditions, and low cost. SGES is one of the ideal alternatives for wind power and photovoltaic energy storage in areas lacking PHES construction conditions.
