Hydrogen Generation

Storing Power,

When generating cleaner, renewable hydrogen, Cummins electrolysis technology unlocks one of the most important sources of emission-free power available. We focus on both ends of the hydrogen equation, with expertise in hydrogen production as well as hydrogen fuel cells designed for numerous applications.



The electrolyzer splits water into hydrogen and oxygen. The hydrogen generated can then be used in industrial, chemical, or short- and long-term power applications. Cummins offers both alkaline or PEM electrolyzers as core technologies in a range of systems.

On-site hydrogen production .

On-site hydrogen production

Cummins on-site hydrogen generators–the HySTAT™ and HyLYZER™–are the result of years of continuous improvements in performance, flexibility, quality, and durability since 1948.

Our advanced systems range from 1Nm3/h up to 1000Nm3/h, ideal for indoor or outdoor housing, and deliver high-purity hydrogen with secure, simple operations, low maintenance, and worldwide support from installation to start-up.
