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.

Ready to see how utilities are deploying compressed air as the clean, reliable backbone of future grids?

Tree AirBattery: Modular CAES for Sustainable Mining

Mining operations face steep energy costs and reliability risks. Energy can account for roughly 30% of a mine’s operating expenses, and off-grid power can cost up to $300/MWh. Traditionally this demand is met with diesel generators, which are expensive to run and maintain, expose mines to fuel-price volatility and carbon taxes, and generate significant emissions. Batteries (lithium-ion) offer emissions savings but carry safety and lifecycle downsides: they degrade over years and can ignite, releasing toxic smoke in confined spaces.

Data Centre Efficiency

Cooling systems alone account for up to 40% of a data centre's electricity usage. With millions of kilowatt-hours consumed annually to prevent servers from overheating, the cost of keeping data centres cool is both financially and environmentally significant.
