Proven Core Technology

The power industry relies on technologies with a proven track record of dependable performance. SustainX combines mature industrial components with its patented thermodynamic and control innovations to deliver a storage solution that is comprised almost entirely of steel, water, and air.

SustainX's ICAES utilizes mechanical subsystems that have demonstrated decades of service in the wind and power generation industries. Proven electric-machine and crankshaft technology, in conjunction with our patented isothermal cycling technology, offers a high-efficiency means of transforming electrical energy to mechanical energy and vice versa. Additional benefits include known component lifetimes and well-understood maintenance intervals, resulting in a storage system with inherently low cost, long lifetime, and low maintenance.
