Nikkiso launches industry-leading fuel gas supply systems to support next-generation marine engines
12 December 2025
Temecula, Calif. – Nikkiso Clean Energy & Industrial Gases Group (Nikkiso CE&IG) has announced a major milestone in marine innovation with the launch of a new high-pressure fuel gas supply systems (FGSS) specifically designed to power the next generation of cleaner, more efficient ships with lower emissions and greater efficiency.
Nikkiso CE&IG’s innovation in FGSS manufacturing represents a future-proof solution - engineered to deliver and sustain pressures well beyond today’s standards of 380-420 bar, regardless of fuel source. This capability positions Nikkiso CE&IG at the forefront of marine propulsion technology, ensuring compatibility with current and next-generation engines as shipbuilders and operators transition to lower-carbon fuels like liquefied natural gas (LNG), ethane, ammonia and hydrogen.
For decades, most marine vessels have relied on low-pressure diesel systems, typically operating around 320 bar. However, as the global shipping industry accelerates toward decarbonization and tighter emissions standards, the demand for higher-pressure, more efficient fueling and alternative fuel sources is rising.
Nikkiso CE&IG’s innovation is built on the foundation of tens of millions of operating hours FGSS at pressures well beyond 420 bar in both offshore and onshore applications. For the marine market, Nikkiso CE&IG has supplied 40 vessels with FGSS operating at more than 380 bar, accumulating more than 500,000 operating hours of service.
Mike Wells, Vice-President of Product Management & Innovation at Nikkiso CE&IG, said: “This innovation is in direct response to the evolving demands of our clients, who look to us for reliable operation and a track record of delivery.
