Plug 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.

Ludlow Electrochemical HardwareIn Queensbury, Ludlow Electrochemical Hardware builds hydrogen technology and electrochemical equipment, including fuel-cell test stations and hydrogen-pump platforms. Established in 2014, the company grew from Dr. Ludlow’s electrochemical hydrogen-pump work, which dates to 2006, and operates from a 5,700-square-foot facility with round-the-clock testing capabilities. Ludlow also provides third-party testing and custom design and fabrication for fuel-cell, electrolysis, and hydrogen applications.QUEENSBURY, NY
Hydrogen Energy Systems, LLCFounded in Akron in 2007, Hydrogen Energy Systems, LLC develops hydrogen-fuel technology for internal-combustion engines, centered on its patented Hydrogen Mixing Block™. The device replaces a carburetor or electronic fuel injector so small engines can run mechanically on 100% compressed hydrogen, and the company has tested the system across engines from 6 to 13 horsepower. HES has also demonstrated the technology in a portable generator and a six-passenger golf shuttle prototype.AKRON, OH
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
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
