Identification

Cheesecake Energy’s eTanker is a stationary, medium-long-duration energy storage solution which delivers cheap, reliable, efficient energy storage in a modular, containerised package. ​ The technology stores energy in the form of heat and pressurised air, adapting ex-service truck engines with our patented modifications to become zero-emission electrical power-conversion machines for putting energy into storage and recovering it from storage. Our proprietary system architecture unlocks low-cost performance in a compact footprint that represents a step change in compressed air energy storage capabilities.​ The system is safe, straightforward to operate, has a lifetime of up to 25 years and can deliver turnaround efficiencies of 65-70%. ​​​ eTanker can discharge at full power for up to 20 hours at 30-40% lower cost than lithium-ion batteries and can be deployed flexibly as power and energy are scaled separately from one another.
