Energy Vault (2011; Lugano CH; 9 staff; https://energyvault.ch/)
An energy storage company that uses gravity to regain electricity from lifted blocks, a mechanism comparable to pumped hydro plants. They employ a low tech but mostly automated solution that relies on proven technology to cheaply store energy. Many of the drawbacks of pumped hydro plants can be circumvented and it can be employed on a much smaller and local scale. The plants have “a capacity of between 10 and 35MWh and a power output of between 2 and 5MW”.
As energy storage is a key technology for the transition to renewable energies low-cost storing solutions are important for a stable grid.
Leadership: Robert Piconi (CEO)
Note: Not to be confused with Energy Vault from Chicago an eclectic infrastructure development company for smart-grid and storage.
