Skip Tech is working to deliver a commercial hydrogen-bromine flow battery to address the needs of the Long Duration Energy Storage (LDES) market.

The founders have achieved a scientific breakthrough where previous attempts have failed. They are able to contain the hydrogen-bromine reaction through a patent-pending novel liquid membrane, innovative mechanical engineering, and material science.

This breakthrough allows Skip Tech to create a sustainable, scalable, and cost competitive battery that combines high energy density, customizable power output and safety better than any competitor currently on the market.

Skip Tech batteries work through a reversible electrochemical reaction that uses hydrogen bromide (HBr) as the electrolyte. HBr is split into H2 and Br2 during the charging phase when power flows into the system. The hydrogen ions react at the anode to become hydrogen gas and the bromide ions react at the cathode to become liquid bromine. During the discharging phase, the hydrogen gas and the liquid bromine are split into their corresponding ions again and release energy. The recharge cycle adds electric energy to the system and the HBr splits back into H2 and Br2. No chemicals are permanently changed or lost during this process since the batteries are closed cycle systems.
