Hystar Announces Strategic Collaboration with McDermott to Develop 100 MW Green Hydrogen Plant Design
Hystar AS (www.hystar.com), a leading provider of the world’s most efficient PEM electrolysers, today announced a strategic collaboration with McDermott (www.mcdermott.com) 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 modularized 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 optimized 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.
