Stargate Hydrogen has reached an agreement to become the official aftermarket provider for Cummins HySTAT alkaline electrolyser systems. This partnership covers support and replacement parts for over 400 installed units globally.
Why it matters
The deal ensures long-term operational continuity for hundreds of industrial hydrogen production sites currently relying on legacy HySTAT infrastructure. It also signals a shift in aftermarket support strategies for large-scale energy equipment as original vendors optimize their portfolios.
The agreement covers more than 1,000 stacks deployed across 65 countries. This setup provides essential maintenance for an installed base of 400 HySTAT alkaline electrolyser systems, which use electrochemical cells to split water into hydrogen and oxygen.
The players
Stargate Hydrogen
A hydrogen technology firm founded in 2021 that specializes in electrolysis innovation and support services.
Cummins Inc
A global power leader that develops and manufactures hydrogen production technologies and energy infrastructure components.
The details
Stargate Hydrogen will manufacture and supply replacement stacks and provide technical services for the legacy HySTAT fleet. Alkaline electrolysers utilize a liquid alkaline electrolyte solution, typically potassium hydroxide, to facilitate the transport of ions between electrodes. As the approved vendor, Stargate must manage the lifecycle of these units, ensuring that performance metrics for gas purity and energy efficiency remain consistent with the original design specifications.
