Hydrogen Liquefaction Plants

Joule offers unique, complete liquefaction plant designs and technology to propel the global energy transition.

Our liquefiers are the most energy-efficient designs on the market utilizing hydrogen as the refrigerant in the main liquefaction cycle.


Reliability and Operability

Plug’s liquefaction technology centers around a gaseous nitrogen precooling stage and gaseous hydrogen refrigeration stage to reduce the required equipment. This design increases plant reliability and availability while minimizing parasitic losses like heat leak and seal gas losses.

Optimal Plant Efficiencies

Plug’s liquefiers are guaranteed to have a specific energy consumption (SEC) below 11 kWh/kg.

Maximized Plant Availability

Our 30-ton-per-day liquefiers utilize two, 50% hydrogen refrigeration compressors to maximize plant availability.

Trackable Performance

Plug’s liquefiers are fully instrumented to provide operators actionable information in real-time and track liquefier performance over the life of the plant.

With our ultra-efficient liquefiers, we strive to provide the lowest-cost liquid hydrogen to help promote the global hydrogen economy. Our liquefiers streamline the process of generation, liquefaction, and distribution.

Joule’s 15 ton-per-day and 30 ton-per-day liquefiers are engineered for high efficiency, reliability, and operational flexibility — providing consistent liquid hydrogen to customers.
