Through our strong legacy and unique knowledge in advanced thermal cycle engineering, we have become a recognized expert in large scale Concentrated Solar Power Plants (CSP), a technology allowing renewable production on a stable basis, night and day, thanks to its ability to store large quantities of energy in a cost-efficient way.
1) Battery Storage. One of the most common and effective ways to store solar energy is through batteries. Batteries store excess energy generated during sunny periods for use during cloudy days or at night. Lithium-ion batteries, in particular, have gained prominence due to their high energy density and long lifespan.
