Woniltni

Woniltni makes industrial equipment that converts liquefied natural gas (LNG), natural gas chilled to an extremely cold liquid state for transport, back into usable gas for power plants and city-gas networks, and also develops hydrogen-related technologies including hydrogen storage alloys and hydrogen reformers that extract hydrogen fuel from fossil fuels.

Its customers include energy infrastructure operators and, notably, South Korean naval defence programmes, where it supplies components related to air-independent propulsion systems for submarines. The company is listed on KOSDAQ, South Korea's tech and small-cap exchange, and its business spans both the LNG energy infrastructure and defence supply chains.
