Product Applications

Large-scale centralized green hydrogen production base: Integrated with renewable energy sources such as wind power and photovoltaics; used in integrated hydrogen production, storage, and transportation projects; supports hydrogen pipeline transmission and liquefaction storage & transportation.

Distributed hydrogen production in industrial parks: Replaces traditional coal-to-hydrogen and grey hydrogen supply; provides a stable hydrogen source for oil refineries, chemical plants, steel industry, etc.; can be integrated into hydrogen energy comprehensive stations.

On-site hydrogen production at hydrogen refueling stations: Solves the problems of high hydrogen transportation costs and unstable supply; especially suitable for small refueling stations far from the main pipeline network; supports the integrated development of 'wind-solar-hydrogen'.
