Product overview

Engineered for large-scale hydrogen production at 20 MW per line

Designed for larger hydrogen production plants. The 20 MW line lowers CAPEX and reduces plant complexity when scaling up production capacity.

The Metacon 20 MW alkaline electrolyser module combines PERIC's proven proven electrolyser technology with Metacon's expertise in engineering, automation, control systems and plant integration. The result is a complete, scalable hydrogen production solution designed for reliable operation and large-scale hydrogen production.

Suitable for applications such as refineries, ammonia production, steel manufacturing and large renewable hydrogen hubs, the 20 MW module can be deployed individually or in parallel as project capacity increases. By using larger production blocks, projects can reduce installation complexity and the number of system interfaces while retaining the flexibility needed for commercial operation.

The compact multi-level architecture can reduce steel structure costs by up to 30%, piping-related costs by up to 50%, and area-related infrastructure costs by up to 70% compared with conventional building-based solutions.

Benefits

Reduced footprint and lower CAPEX
Latest-generation PERIC pressurized alkaline stacks
Lower hydrogen cost over lifetime
One partner from design to service
European compliance, documentation and support
