A leading company in large-scale hydrogen production has delivered a powerful electrolyzer system that will generate green hydrogen for one of the world’s 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.
