Largest electrolyzer system in US goes live in New York State

Cummins Inc.’s zero-emissions division, Accelera, has deployed the largest US-built proton exchange membrane (PEM) electrolyzer system—a 35 MW unit—at Linde’s hydrogen plant in Niagara Falls, New York. Powered entirely by local renewable hydroelectric energy, this system produces green hydrogen by splitting water into hydrogen and oxygen without emissions. Manufactured in Minnesota, the modular and scalable electrolyzer is designed to decarbonize industrial processes and enable commercial-scale green hydrogen production, supporting both energy efficiency and regional industrial needs. The project marks a significant milestone in advancing clean hydrogen technology in North America and reinforces New York’s leadership in the clean energy transition. Beyond environmental benefits, it is expected to stimulate local job creation and economic growth. Accelera, with over 600 PEM electrolyzers deployed globally—including previous 20 MW and 25 MW systems in Canada and Florida—demonstrates its commitment to expanding green hydrogen production capacity.
