Gravity-based long-duration energy storage
Energy Vault develops gravity-based long-duration energy storage solutions. Their proprietary technology uses composite blocks and automated crane systems to store energy by lifting and lowering heavy masses, providing grid-scale storage with high efficiency and long life.
Founded in 2017 by Robert Piconi and Andrea Pedretti, Energy Vault pioneered the gravity energy storage concept with tower-based systems. The company went public on the NYSE in 2022 and has expanded its product portfolio to include a range of gravity storage architectures.
