Industry Problem

Renewable power requires affordable, durable storage for periods longer than conventional lithium-ion batteries typically serve.

R&D Focus

Thermodynamic long-duration energy storage, closed-loop CO2 systems, turbomachinery, and grid-scale deployment.

Innovative Solution

The CO2 Battery stores energy by compressing and condensing CO2, then expands it through a turbine to generate electricity.

Solution Effectiveness

The company built a 2.5 MW / 4 MWh demonstration plant and has reported a commercial pipeline of about 9 GWh.
