HyLink Alkaline 23 is a new outdoor pressurized alkaline electrolyzer system. The 50-megawatt electrolyzer module is designed for the implementation of triple‑digit megawatt projects and reduces total installed costs (TIC) on the customer side by up to 50%. At the core of HyLink Alkaline 23 is this company’s proven second‑generation 30‑bar(g) pressurized 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. The new 50 MW-module combines five times the installed capacity of the previous solution with a design fully optimized for outdoor deployment.

As part of the new system design, key plant components have been centralized, additional components such as air cooling have been integrated as standard, and the level of prefabrication has been significantly increased. At the same time, system interfaces have been optimized. This substantially simplifies installation and commissioning while delivering significant cost reductions for the overall green hydrogen plant (TIC). In a 100-MW project scenario, the number of required electrolyzer modules is reduced from ten to two. The construction of a dedicated electrolyzer building is no longer necessary. HyLink® Alkaline 23 directly addresses the current requirements of large‑scale hydrogen projects in energy‑intensive industries such as refining, chemicals, and ammonia production, where hydrogen supply is being built up on an industrial scale with a lower carbon footprint. — Sunfire SE, Dresden, Germany
