Sunfire has launched the HyLink® Alkaline 23, a new outdoor pressurised alkaline electrolyzer system, significantly reducing total installed costs (TIC) for industrial electrolysis projects.

At the core of HyLink® Alkaline 23 is Sunfire’s proven second-generation 30 bar(g) pressurised alkaline stack. The higher operating pressure significantly reduces downstream hydrogen compression requirements. The stack technology is already in operation in industrial plants across Europe, where it has demonstrated reliable performance in the production of green hydrogen.

 Sunfire has developed its existing 10-MW pressurised alkaline module for deployment in triple digit megawatt projects. The developed 50-MW module combines five times the installed capacity of the previous solution with a design fully optimised for outdoor deployment. For example, in a 100-MW project scenario, the number of required electrolyser modules is reduced from 10 to two and a dedicated electrolyzer building is no longer needed.

Christian von Olshausen, CTO of Sunfire, said: “With the new system, we are applying five key levers to improve project economics: First, we increase module capacity from 10 to 50 megawatts, significantly reducing material and component requirements. Second, the solution is fully designed for outdoor operation, eliminating buildings and building related infrastructure as major cost drivers. Third, key interfaces are already integrated into the system, substantially reducing complexity. Fourth, a high degree of prefabrication shortens installation time and minimises onsite effort. Fifth, the system is based on our proven 30bar stack technology with validated performance. Taken together, these five improvements reduce total installed costs for our customers by up to 50%.”

Nils Aldag, CEO of Sunfire, added: “We have actively shaped this market and, over the past 16 years, implemented projects ranging from several hundred kilowatts to low megawatt capacities and up to full industrial scale. Throughout this process, we have worked closely with our customers and developed a clear understanding of what matters in real‑world applications. Accordingly, our current 100-MW projects are repeat orders from existing customers.”
