In sites where plant space is at a premium, customers may choose to install their electrolyzers outside. In other cases, customers may prefer to configure an electrolyzer for a more turnkey operation. To fulfill those requirements, Nel Hydrogen recommends containerization.
The M Series MC250 and MC500 units are supplied and placed in free-standing containers for ultimate flexibility.
Containerized M Series electrolyzers can generate up to492 Nm3/hour of hydrogen gas at 99.9995% purity on-demand. Common applications include industrial process gas, renewable energy storage, and hydrogen fueling.
Features
Pure hydrogen at process pressure – up to 30 barg (435 psig) hydrogen and 99.9995% purity
Cost-effective hydrogen supply – tracks electric costs
Increased safety – caustic chemicals are not used
Virtually zero stored hydrogen – removes the hazard of flooding the space
Large capacity with minimal footprint – only a fraction of space needed compared to storing large volumes of gas or liquid hydrogen
Dependable supply of hydrogen—field-proven reliability
Containerized design – versatile plant configurations
Automated – safe operation without manual involvement
