German electrolyzer manufacturer Sunfire has launched HyLink Alkaline 23, a new 50-megawatt outdoor pressurized alkaline electrolyzer system, calling it the platform that will carry industrial green hydrogen projects from pilots into triple-digit-megawatt deployments.
The Dresden-based company says the new module multiplies the installed capacity of its previous 10-megawatt design by five and reduces total installed costs by up to 50% for large green hydrogen plants. HyLink Alkaline 23 is built around Sunfire's second-generation 30 bar(g) pressurized alkaline stack, which is already running in industrial reference plants across Europe.
How the design cuts costs
Higher operating pressure trims downstream compression requirements, while centralizing balance-of-plant components, integrating air cooling as standard and increasing prefabrication shortens installation. In a 100-megawatt plant scenario, Sunfire estimates the new module reduces the number of required electrolyzer units from 10 to two and eliminates the need for a dedicated electrolyzer building.
Market context
The launch lands as Western project developers struggle to hit unsubsidized cost targets and as the United States winds down hydrogen hub tax incentives. By contrast, European projects continue to commit gigawatt-scale offtake. Sunfire has shipped hardware into several of those, and competes against long-duration storage and PEM electrolyzer rivals for refinery, ammonia and steel customers.
Adjacent customer momentum
Solid-state and battery players are also racing to scale industrial systems for the same heavy-industry decarbonization market that Sunfire serves. Sunfire's HyLink Alkaline 23 will be available for orders from project developers planning triple-digit megawatt installations from 2027 onward, the company said.
Outlook
Whether HyLink can hold its 50% cost-down claim through field deployment will be the key question for project sponsors. With its existing 10-megawatt fleet as proof, Sunfire is one of the few Western suppliers with a real shot at delivering on the gigawatt-class projects that European policy still backs.
