The Air Battery represents a quantum leap in traditional CAES technology. Housed in a purpose-fitted container, the Air Battery provides flexible energy storage able to be scaled over time or physically moved to different sites. Which Air Battery is right for me? The best way to answer this is to establish how much energy you need and for how long.
Designing a compressed air energy storage system that combines high efficiency with small storage size is not self-explanatory, but a growing number of researchers show that it can be done. Compressed Air Energy Storage (CAES) is usually regarded as a form of large-scale energy storage, comparable to a pumped hydropower plant.
When needed, the system releases the high-pressure air through water chambers to drive turbines and generate electricity. “With the AirBattery, we’re introducing a storage solution that finally matches the scale and rhythm of renewable energy,” said Or Yogev, Founder and CEO of Augwind.
The project’s multiweek storage cost per kilowatt-hour of only $10 to $15 positions it as a competitive alternative to battery-based solutions. Augwind is currently working with utilities, energy traders, and cavern owners in Germany to secure permits and finalize system design. AirBattery also promises to reduce grid expansion costs.
Unlike lithium-ion batteries, AirBattery is built with local materials, runs in a closed water system, and offers nearly unlimited storage duration, limited only by the size of the cavern. German engineering firm Fichtner Group has validated the system’s performance and economic feasibility.
The high pressure system with a storage volume of only 0.55 m3 that we mentioned earlier, is an example of this type of system. 9 As noted, its electrical efficiency is only 11-17%, but the system also produces sufficient heat to produce 270 litres of hot water per day.
