This technology is a membrane-free electrolyzer that generates acidic and alkaline product streams from saltwater using hydrogen-mediated redox reactions, enabling efficient, low-voltage operation without ion-exchange membranes or fouling.
Large volumes of acids and bases are crucial for industries such as water treatment, mining, manufacturing, and carbon capture, among others. Conventional chlor-alkali and other electrolysis systems typically rely on expensive ion-exchange membranes and high-purity water, making them costly and prone to degradation. There is a need for an energy-efficient, membrane-free electrolysis system capable of processing impure or saline feedstocks without sacrificing performance or electrode longevity.
This technology enables the direct, low-energy conversion of saltwater into separate acid and base streams, eliminating the need for costly membranes or purified water. By using hydrogen as a redox mediator, it achieves efficient ionic separation at low voltages while avoiding scaling and fouling. The system supports continuous, durable operation using seawater or brine, lowering cost and energy use for chemical production and desalination byproduct treatment.
