Are gravity batteries a viable alternative to a mined lithium ion?

Their costs fluctuate with geopolitics and supply chain dependencies—China currently controls an estimated 72% of the lithium-ion market. These factors push many governments and companies to explore alternatives that can operate without relying heavily on mined materials. A gravity battery, at its core, leverages potential energy.

Can gravity batteries coexist?

Gravity batteries, pumped hydro, lithium-ion systems, hydrogen fuel cells, and thermal storage could all coexist, each playing its part. Gravity batteries shine for large, long-term capacity needs in locations suited to tall structures or deep shafts.

Are gravity batteries a new technology?

Gravity batteries are not an entirely new concept. Pumped hydroelectric storage, a century-old technology, lifts water from a lower reservoir to a higher one using surplus power, then releases it to generate electricity when needed.
