Korea Gas Corporation (KOGAS) had “successfully localized and verified” an ultra-low-temperature liquefied natural gas (LNG) pump, calling it a Korea-first achievement, according to the company’s statement.
The pump was selected in 2020 as a government-led localization project. Hyundai Heavy Industries Turbomachinery (HHI-TMC) developed ship-use prototypes over three years to secure core technology, but commercialization was delayed due to difficulties in conducting on-site demonstrations.
KOGAS signed an agreement with HHI-TMC in April last year to support localization of ultra-low-temperature pumps for land-based LNG terminals under Korea’s “K-testbed” program, which it described as a government-led platform that opens public infrastructure to support R&D, field demonstrations and market entry for startups and small and medium-sized enterprises.
KOGAS has taken part in the program for four consecutive years since 2021. Major components in the newly developed pump were designed and manufactured using domestic technology, including a cryogenic motor from the Korea Marine Equipment Research Institute (KOMERI) and bearings from Hanil Hightech.
For on-site validation, KOGAS provided a commissioning environment at its Pyeongtaek LNG Terminal for about seven months, from May through November 2025, and jointly conducted monitoring and reliability evaluations with the Korea Institute of Machinery & Materials (KIMM) and the Korean Register.
Korea Gas Corporation (KOGAS) is a Korean corporate entity established in 1983 that discloses activities spanning LNG infrastructure development and operation, including LNG terminal construction and operation and management of a nationwide gas supply pipeline network; it also states it imports LNG, regasifies it, and supplies gas to downstream customers, and discloses a total pipeline length of 5,248 km.
Hyundai Heavy Industries Turbomachinery (HHI-TMC) is a manufacturing business that describes its activities as producing turbomachinery, including cryogenic pumps.
