Iljin Hysolus

Iljin Hysolus makes high-pressure hydrogen storage tanks, the cylinders that hold compressed hydrogen fuel inside vehicles such as passenger cars and commercial buses, as well as diesel particulate filters that reduce exhaust emissions from older vehicles.

Its customers include hydrogen-vehicle manufacturers and operators of commercial fleets, and its products sit within Korea's government-supported clean-energy and emissions-reduction programmes. Listed on KOSPI, Korea's main stock exchange, the company operates across two distinct lines: hydrogen storage systems and environmental emissions-control devices.
