Salgenx Unveils Hybrid Solar-Thermal Power System with Integrated Desalination and Grid-Scale Saltwater Battery Storage

Salgenx announces hybrid energy system with solar PV-driven supercritical CO₂ power generation, waste-heat desalination, and Salgenx saltwater battery storage.

MADISON, WI, UNITED STATES, October 17, 2025 /EINPresswire.com/ -- Salgenx, a leader in renewable energy innovation, has unveiled a revolutionary hybrid solar-thermal power generation system that combines photovoltaic, supercritical CO₂ turbine, and desalination technologies into one integrated platform—storing all generated electricity in Salgenx’s patented saltwater flow batteries for grid-scale deployment.

A New Standard for Solar Efficiency
• The system uses solar photovoltaic (PV) panels to power a supercritical CO₂ compressor in a Brayton Cycle, dramatically reducing internal power demands in the turbine cycle.
• At the same time, concentrated solar thermal collectors heat the compressed CO₂ to 500 °C or higher, enabling turbine efficiencies exceeding 40 percent—well above traditional thermal cycles.
• This dual solar input—electrical and thermal—maximizes total conversion efficiency and provides stable, dispatchable electricity rather than intermittent power.

Desalination from Waste Heat
• The waste heat from the turbine’s thermal cycle, normally released to the environment, is now harnessed to desalinate seawater or brine, converting low-value heat into a valuable freshwater by-product.
• This approach provides both clean power and clean water, addressing two global challenges simultaneously.

Stored in Salgenx Saltwater Batteries
• All generated electricity is stored in the Salgenx Grid-Scale Saltwater Battery, a non-toxic, flow-type energy storage system capable of handling megawatt-scale power.
• The battery uses abundant saltwater electrolytes and offers multi-day storage capacity, eliminating the need for lithium or rare-earth materials.
• With this configuration, solar-generated electricity can be dispatched on demand, stabilizing the grid and supporting 24-hour renewable operation.

Economic and Environmental Advantages
• Compared with standard solar PV (22 percent efficiency), the hybrid sCO₂ system offers greater total energy yield and firm, dispatchable power without relying on costly lithium-ion batteries.
• Integrated desalination adds a secondary revenue stream and enhances the sustainability profile of remote or coastal installations.
• The combined system reduces carbon intensity, water scarcity, and grid instability—three of the most pressing issues facing renewable energy adoption today.
