thermal energy storage

Cache Energy provides electrified heat and long-term thermal energy storage for global infrastructure. Its core system uses a chemical-bond storage material that does not react to flame, heat, or cold, allowing room-temperature storage with no moving parts in the charger/discharger, a 30+ year service life, and >90% thermal efficiency. The company offers a lease model with zero upfront capex, contract-backed maintenance and >99% uptime, and an advanced software stack for monitoring, optimization, and energy price forecasting.

ChefsFridge Co. operates a peer-to-peer food marketplace using temperature-controlled smart kiosks that connect local farmers and chefs directly with consumers. Kiosks offer 24/7/365 access to fresh, curated food, with multi-compartment temperature zones (frozen, refrigerated, ambient) and precise control. Consumers browse and reserve items via a mobile app and unlock compartments for pickup. The company also spun off ArcticRx and CryoVase to apply its thermal technology to pharmaceutical logistics and luxury perishables.

Electrified Thermal Solutions develops the Joule Hive™ Thermal Battery, which converts off-peak electricity into up to 1,800°C heat stored in electrically conductive firebricks (E-bricks) and delivers it to furnaces, boilers, kilns, or turbines. The technology was developed over 12+ years of materials research at MIT. The first commercial-scale unit was commissioned at Southwest Research Institute in San Antonio, Texas in February 2026. Headquarters and E-brick production facility are in Charlestown, MA, with a European office in Amsterdam.
