SustainX's isothermal compressed air energy storage (ICAES™) technology is a site-anywhere, zero-emissions solution that enables power- and energy-scalable compressed air storage, without the need for caverns or natural gas combustion. SustainX achieves isothermal cycling by combining patented innovations with a design centered on proven industrial principles and mature core components; i.e., a mechanical drivetrain based on an electric machine and crankshaft. The result is long operating life and a disruptively low levelized cost of energy (LCOE) as compared to competing storage technologies.
