Hystar announces strategic collaboration with McDermott to develop 100 MW green hydrogen plant design

Hystar AS, a leading provider of the world’s most efficient PEM electrolysers, today announced a strategic collaboration with McDermott to develop a comprehensive 100-megawatt (MW) green hydrogen plant design. This collaboration marks a significant milestone in Hystar’s mission to accelerate global deployment of its large-scale green hydrogen solution.

Under the agreement, Hystar will provide its proprietary, high-efficiency and high-safety PEM electrolyser technology. McDermott will leverage its extensive global expertise as an engineering, procurement and construction (EPC) provider for major energy infrastructure. With more than a century of engineering excellence, McDermott has delivered numerous large-scale hydrogen, ammonia, and low-carbon projects. Its portfolio includes pre-FEED, FEED and EPC execution for blue and green hydrogen facilities, ammonia plants, hydrogen hubs, and modularised energy projects worldwide.

By combining Hystar’s game-changing electrolyser technology with McDermott’s proven hydrogen execution expertise, the companies will develop a full-facility reference design optimised for scalability, flexibility, safety, and cost efficiency.

The 100 MW reference plant will serve as a blueprint for future commercial hydrogen projects, enabling faster development and streamlined delivery for industries such as refineries, ammonia, steel, heavy transport, and synthetic fuels. The collaboration aims to offer customers an integrated, ready-to-deploy plant architecture that reduces technical risk, simplifies procurement, and shortens time to market.

The announcement was made during the Hydrogen Technology World Expo in Hamburg.

“This collaboration reflects our shared commitment to advancing the energy transition,” said Rob Shaul, McDermott’s Senior Vice President of Low Carbon Solutions. “By combining McDermott’s engineering and EPC expertise with Hystar’s innovative PEM technology, we’re creating a scalable solution to support future green hydrogen projects.”

Fredrik Mowill, Hystar CEO says: “Working with McDermott ensures that Hystar’s leading PEM technology can be scaled efficiently and deployed worldwide through a proven EPCI framework.”

This collaboration further strengthens Hystar’s position as a leading technology provider and demonstrates its continued commitment to enabling the transition to cost-effective green hydrogen worldwide.
