Largest US-built 35 MW PEM electrolyzer deployed at hydro-powered plant in Niagara Falls
InterestingEngineering.com | Sep 05, 2025
A leading company in large-scale hydrogen production has delivered a powerful electrolyzer system that will generate green hydrogen for one of the worlds largest industrial gas companies at their facility in New York.
Developed by Accelera, the zero-emissions business segment of Cummins Inc. the 35-megawatt (MW) proton exchange membrane (PEM) electrolyzer is the largest operational system of its kind in the US.
Powered by local renewable hydroelectric energy, the system is designed to generate green hydrogen at commercial scale and will support production at Lindes plant in Niagara Falls in New York State.
The successful delivery of this 35 MW electrolyzer system is a significant milestone for Accelera and for the advancement of clean hydrogen technology in North America, Des McMenamin, electrolyzers general manager at Accelera said.

The electrolyzer is trivial and useless, and given that energy, precious metals, is being wasted on this cheap exercise in greenwashing fossil fuels is an ethical disgrace of the highest order, particularly with electricity prices rising through the roof.
