Membravo

Membravo is a technology startup that develops and manufactures advanced, high-performance polymer membranes designed for gas and liquid chemical separations in harsh industrial environments. Founded as a spinout from SRI International, the company utilizes proprietary membrane platforms engineered to withstand extreme temperatures, pressures, and chemically aggressive conditions where traditional separation technologies often fail. Their hollow-fiber membrane solutions act as selective molecular sieves, enabling the efficient recovery and purification of hydrogen, helium, solvents, and other critical materials without requiring energy-intensive cooling or pressure-swing processes. The technology is designed for modular, retrofit-ready integration into existing industrial infrastructure, allowing for seamless scaling from pilot deployments to full-scale operations.

By providing robust separation capabilities, Membravo helps industries across sectors—including energy, water treatment, semiconductor manufacturing, and chemical processing—reduce energy consumption, minimize waste, and improve resource recovery. The company addresses significant industrial bottlenecks where valuable products are otherwise lost or require costly processing. Their technology, which leverages over $10 million in U.S. Department of Energy–funded research, is aimed at decarbonizing heavy industry and increasing operational efficiency by enabling higher throughput and improved purity in complex process streams. The firm is currently engaged in pilot project discussions and deployments with major energy and industrial companies.
