HydroCosm 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.
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
HYDRO-ELECTRENERGY INCHydro-Electrenergy Inc. is developing the Hydro-Electrenergy system, a proposed perpetual-motion apparatus intended to generate a continuous electric current by using gravity, buoyancy, and other natural forces rather than burning fossil fuels. The company says the electricity could also support hydrogen extraction from water, with a decentralized setup designed to provide energy without ongoing fuel costs or emissions. Its work centers on replacing conventional fossil-fuel energy with what it describes as a direct use of nature’s powers.BAY SHORE, NY
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
Plug Power IncPlug Power develops and manufactures hydrogen fuel-cell and hydrogen-generation technologies as part of an end-to-end hydrogen ecosystem. The company says it created the first commercial market for fuel cells in material handling and has expanded into electrolyzers, hydrogen production and liquefaction, cryogenic infrastructure, and power generation.SLINGERLANDS, NY
