Founded in 2020 by four MIT PhD alumni, Amogy is known for turning ammonia into usable electricity for industries where conventional electrification is difficult. Its patented cracking technology has been proven in demanding settings, including a 2022 tractor demonstration and the retrofit of the NH3 Kraken, a 1957 tugboat that became the world’s first carbon-free ammonia-powered vessel. The company now operates ATHENA, a Houston testing and manufacturing facility opened in 2025 as it moves from demonstrations toward commercial deployment.
First AmmoniaFounded by CEO Joel Moser, First Ammonia is developing modular plants that make electric ammonia from water, air and variable renewable energy. The New York-headquartered company’s flagship facility in Victoria, Texas, is planned as a commercial-scale plant designed to adjust production to changing renewable power and is expected to begin operations in 2029. Its team brings experience in ammonia plant development, chemical and renewable-energy projects, infrastructure finance and energy policy.New York, 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
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
ETCH, IncFounded by Johns Hopkins materials scientist Jonah Erlebacher, ETCH, Inc. develops clean hydrogen and solid carbon from natural gas through its patented ETCH Process™. The process produces no carbon dioxide or toxic waste and uses no water, while scaling from distributed installations to utility-scale facilities. ETCH’s technology is designed to decarbonize existing industrial and power assets while creating usable solid carbon as a coproduct.BALTIMORE, MD
