PWRJOULE

Its design drops the complex pumps and membranes of conventional flow batteries in favor of solid state pumps, and uses a non-flammable, low-degradation chemistry. The company has completed proof of concept at technology readiness level 3 and is working toward levels 4 and 5 through joint R&D and SBIR-funded work, with plans for pre-commercial prototypes for utility and microgrid pilots. Target uses include grid storage, remote microgrids, EV charging buffers and backup power.

PWRJoule is based in Yuma, Arizona. It has partnered with Huron Industries, a woman-owned small business with Defense Department contracting experience, on SBIR and other government work.
