Our First Innovation: CHEX Energy Storage
CHEX Energy Storage (CHEX) is our award-winning, patented energy storage technology, designed to solve key challenges associated with renewable energy integration, including energy curtailment and the need for long-duration storage solutions.
By combining compressed gas, water, and hydraulic systems, CHEX ES efficiently stores and recovers energy in a sustainable and scalable way. The technology enables excess renewable energy to be stored and used when demand increases or generation decreases, reducing wasted energy and improving energy reliability.
With a highly scalable design, CHEX can be adapted for different applications, from renewable energy projects to large-scale grid storage. Its sustainable operation avoids the use of harmful chemicals and enables long-duration energy storage without generating chemical waste or direct CO₂ emissions.
