Quest One PEM Electrolyzer Modular Hydrogen Platform
- Scalable Indoor-Solution with 77% system efficiency
- Industrial production of green hydrogen
- Combination of 10 MW blocks to multi-MW systems with electrolysis capacity of 100 MW and more
Highest efficiency and availability for large-scale hydrogen production
Modular, skid-mounted, ready-to-install: The Quest One MHP is a scalable platform for industrial production of green hydrogen based on PEM technology. 10-MW blocks can be combined into multi-MW systems for projects with an electrolysis capacity from 10 to more than 100 MW. The system is ready for indoor installation on pre-assembled skids. It is equipped with integrated process water treatment and an electrical power supply. Optionally, the system can be supplemented with fresh water and hydrogen treatment, as well as process heat recovery or oxygen utilization as required. The Quest One MHP electrolyzer stands out with its unrivalled system efficiency, high availability, and proven maintenance concept, which result in low hydrogen production costs and stable safe operation.
