Founded in 2008, Bettergy Corp. develops and commercializes energy and environmental technologies built around nanopore-engineered membranes. The company began as an energy-storage technology venture studying membrane advances and now applies that expertise to green hydrogen from ammonia, gas separation, water purification, and electrochemical energy systems. Its work has been supported by federal agencies including ARPA-E, the Department of Energy, NASA, and the U.S. Navy, alongside university collaborations with institutions such as the University at Buffalo and Virginia Tech.
Ecolectro, IncBorn from materials research at the University of Puerto Rico and Cornell University, Ecolectro develops membrane technology and electrolyzer systems for lower-cost green hydrogen production. Ithaca-based cofounders Gabriel Rodríguez-Calero and Kristina Hugar built the company around new polymer electrolyte materials designed to address the cost and durability challenges of water electrolysis. Its alkaline exchange materials are intended as a drop-in alternative for PEM electrolyzer stacks and are already in the marketplace.ITHACA, NY
LayerPure Technologies LLCFounded in May 2025, LayerPure Technologies LLC develops ultra-thin, anti-fouling membranes for high-rejection water treatment. Its membranes reach steady-state performance within 30 minutes and deliver more than 93% boron rejection in a single pass without pH adjustment. The company’s team brings more than 25 years of combined experience in membrane science and technology, while its early work has earned recognition in university pitch, venture, and technology-maturation competitions.
Evolve Hydrogen, IncFounded by two Long Island innovators who began experimenting in their garages, Evolve Hydrogen develops polymer-based electrolyzers that produce green hydrogen directly from seawater and other water sources. Its Evolve™ design avoids precious metals and desalination while using injection molding to support faster, simpler manufacturing. In 2022, the Stony Brook company won Phase One of the U.S. Department of Energy’s Hydrogen Shot H-Prize, one of only 10 winners and the sole company from the Northeast.EAST NORTHPORT, NY
HydroCosmHydroCosm develops distributed hydrogen-generation solutions that use existing water operations and pressurized water infrastructure to produce clean energy close to where it is needed. Founded by Frank Zammataro, the company focuses on recovering wasted energy from water systems with small hydroelectric generators and using it to power electrolyzers for hydrogen production. Its work also extends to hydrogen mobility solutions for public and private fleets and collaboration with governments on infrastructure standards.NEW YORK, NY
