Promethean Power Systems
Promethean’s thermal energy storage system uses proprietary phase-change materials to store large amounts of thermal energy. Our thermal battery enables installation and operation of distributed cold storage systems without the need for a diesel generator, thus making it economically viable to chill milk and produce at the source in weak and off grid settings where power is unreliable.

Thermal Battery for Refrigerated Transport
At the heart of our technology is our Thermal Storage System that is fitted on a truck. The technology operates as a battery which stores thermal (cold) energy. The battery consists of a mixture of Phase-Change Material (PCM) and a Heat Transfer Fluid (HTF). To charge the battery, we run a refrigeration cycle that cools the HTF and freezes the PCM. The compressor runs on standard grid electricity and needs about 4 hours of intermittent power to charge the battery which can cool for 8-12 hours.
