Cache Energy develops a thermal storage system that stores energy in chemical bonds inside lime-derived pellets (starting from calcium hydroxide that converts to calcium oxide when heated) and releases heat when rehydrated. The pellets are designed to be stored in piles or silos, moved by conveyor belts or rail, and held under simple containment, with the company saying they can retain charge almost indefinitely. The system currently produces heat up to 550°C and Cache is developing a version capable of ~900°C to reach more industrial markets. Cache reports overall system efficiency around 95%, an hourly production rate equivalent to about 500 kilowatt-hours, and pellet costs of roughly $0.20–$0.40 per kilowatt-hour at current production. The company was founded in 2021 by Arpit Dwivedi and currently has one pilot reactor deployed with a customer. Future plans include shipping more reactors to customers and raising a Series A to scale deployments while keeping equipment and material costs low by using off-the-shelf parts.
