Compressed air and heat can be used to store energy at half the price of lithium-ion.
Cheesecake Energy’s eTanker is a stationary, medium-to-long-term energy storage solution. It stores energy in a modular, containerized way that is cheap, reliable, and efficient. u200b The technology stores energy in the form of heat and pressurized air. Using our patented changes to old truck engines, we can turn them into zero-emission electrical power-conversion machines that can store energy and get it back. Our unique system architecture makes it possible to get low-cost performance in a small space, which is a big step forward for compressed air energy storage. u200b The system is safe, easy to use, can last for up to 25 years, and can save between 65% and 70% on turnaround time. u200bu200bu200b eTanker can discharge at full power for up to 20 hours and costs 30–40% less than lithium-ion batteries. It can also be used in different ways because power and energy can be scaled independently.
Positive facts about eTanker
Can be cycled10,000 times with negligible degradation
Can operate in a wider range of operating environments from -20ºC to +50ºC (-4 °F to +122 °F) compared to lithium-ion systems which are are efficient from 0 °C to +40 °C (32 °F to +104 °F)
70% turnaround efficiency
At the end of its 25 year lifetime, 99% of CEL eTanker can be fully recycled
Up to 40% cheaper than lithium-ion batteries
Less than 7 year payback and as little as 3 years in some key markets
Targeting a €270/kWh total installed price (150kW-30MW, 8 hour duration)
