Founded 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.
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
Marine Dolphin EnterprisesFounded in 2021, Marine Dolphin Enterprises is developing an offshore AEM electrolyzer that splits seawater into hydrogen and oxygen at roughly 10,000 feet below the surface. Its approach uses the ocean’s natural pressure to compress hydrogen during production, while drawing on Stanford-based electrode research led by Chief Science Officer Michael Kenney. The company is advancing prototypes with Product Design Experts and the University of Wyoming’s Hill Lab.SCARSDALE, NY
Power to HydrogenColumbus-based Power to Hydrogen develops and supplies modular Hybrid AEM electrolysers that split water into hydrogen and oxygen, from 10-kW demonstration units to systems built from 250-kW stacks for installations up to 25 MW. Its technology combines renewable-compatible dynamic operation with lower-cost, non-precious-metal components and a simpler balance of plant, and was invented through a U.S. Department of Energy project. Founded by Dr. Paul Matter and Christopher Holt, the company has piloted its systems with partners including Shell, Enel Green Power and EDP.COLUMBUS, OH
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
