April 14 ,Sunfire has launched HyLink® Alkaline 23, 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 percent.
At the core of HyLink® Alkaline 23 is Sunfire’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.
Building on experience gained from ongoing industrial projects in the double‑digit megawatt range, Sunfire has specifically further developed its existing 10-MW pressurized alkaline module for deployment in triple‑digit megawatt projects. 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.
