AirBattery: Modular CAES for Grid Resilience

As lithium-ion batteries degrade and diesel peakers fail net-zero tests, a new class of energy storage is rising — one that spins like a generator, lasts for decades, and uses nothing more exotic than air. Tree’s AirBattery is a containerized, utility-scale CAES system delivering real inertia, black-start capability, and long-duration flexibility — without fire risk, toxic materials, or costly degradation.

This executive report reveals:

• Why low-inertia grids are failing faster, and how mechanical storage buys time.

• The hidden lifecycle costs of battery storage — and why round-trip efficiency isn’t everything.

• How AirBattery outperforms diesel on response time, safety, and lifetime cost.
