Nikkiso Clean Energy & Industrial Gases Group is a wholly owned subsidiary of Nikkiso Co., Ltd., a company publicly traded on the Tokyo Stock Exchange (TSE: 6376). Founded in 1950 and headquartered in Southern California, the group operates in more than 20 countries with over 1,800 employees. Its core focus is cryogenic engineering technologies supporting the energy transition, particularly in hydrogen, ammonia, LNG, CO2, and industrial gases.
The company is structured around six specialized business units: Cryogenic Pumps, Cryogenic Process Systems, Heat Exchanger Systems, Fueling Solutions, Energy Infrastructure and Strategic Projects, and Cryogenic Services. These units deliver bespoke, turnkey solutions and operate independently of molecule sales, meaning the group's revenue derives from engineering and equipment rather than the sale of the gases themselves.
With more than 70 years in operation, Nikkiso CEIG supports energy infrastructure projects across a global footprint. Its technical domains span cryogenic engineering, cryogenic pumps, cryogenic process systems, heat exchanger systems, fueling solutions, energy infrastructure, and cryogenic services - covering the full lifecycle of cryogenic applications from design through ongoing service and support.
