Sunfire Launches 50 MW Pressurized Alkaline Electrolyzer Module

Sunfire has introduced a 50 MW pressurized alkaline electrolyzer module built on its second-generation 30 bar pressurized alkaline stack technology. The system represents a significant scaling increase from the company's existing 10 MW module and is designed for deployment in triple-digit megawatt projects.

The new module incorporates several cost-reduction features, including centralized key plant components, integrated air cooling, increased prefabrication, and optimized system interfaces. The outdoor-optimized design eliminates the need for dedicated electrolyzer buildings and reduces infrastructure requirements.

In a 100 MW project scenario, the modular approach reduces the number of required electrolyzer units from 10 to 2, simplifying installation and commissioning processes. According to Sunfire CTO Christian von Olshausen, the system applies five levers to improve project economics: increased module capacity, outdoor operation capability, integrated interfaces, high-degree prefabrication, and proven stack technology.

The pressurized alkaline stack operates at 30 bar(g), reducing downstream hydrogen compression requirements and lowering overall system complexity. Sunfire notes the stack is already operating in industrial plants across Europe for green hydrogen production.

The system targets large-scale hydrogen applications in refining, chemicals, and ammonia production. CEO Nils Aldag stated that current 100 MW projects represent repeat orders from existing customers, reflecting validated performance in real-world applications.
