• Energy Vault places bricks, one top of another, to store potential energy and lowers bricks back toward ground, to release energy • Fully automated 6-arm crane operated by software, provides up to 5 MW of electricity without interruption • Can charge and discharge between 4 and 50 hours depending on product and customer needs
Charging = consumes electricity Charged Discharging = releases electricity
