The two-year project will assess the scope for blending hydrogen with natural gas in KOGAS’ 5,000km long pipeline.
DNV will evaluate the pipeline network’s suitability for hydrogen blending, provide technical and advisory support to KOGAS’ hydrogen blending test project on Jeju Island and support KOGAS in addressing South Korea requirements in overseeing hydrogen integration and uptake.
Lim Dong Ho, South Korea Market Area Manager at DNV, said, “DNV’s global technical expertise across the entire hydrogen value chain means we are uniquely placed to support the world’s largest liquefied natural gas (LNG) importer KOGAS in creating value from hydrogen while also helping South Korea’s transition to a decarbonised energy future.”
The work plan includes assessing and demonstrating the viability and impact of blending hydrogen with natural gas at various ratios in KOGAS’ transmission pipeline system, advising on the options and the construction and operation of hydrogen injection facilities and equipment.
DNV will also review methods for controlling the concentration of hydrogen blending for customers and providing on-site technical support and data analysis for the hydrogen demonstration project.
The company is currently working globally with a number of gas pipeline companies to safely repurpose gas transmission and distribution networks for the integration of blended 100% hydrogen gas.
Last year, DNV landed a three-year contract to demonstrate the safe use and conversion of pipelines to transport 100% hydrogen in the UK.
It has been engaged to provide the evidence for utilising local transmission systems (LTS) high pressure pipelines by gas distribution company, SGN, which manages around 3,100km of LTS pipelines in the UK.

Using imported LNG, natural gas is responsible for around 26% of South Korea’s power generation capacity and expected to grow to 31% by 2050 as coal and nuclear plants are phased out.
The South Korean Government announced plans to hit Net Zero by 2050, replacing coal-fired power generation with renewable sources and fossil fuelled vehicles with hydrogen-powered and battery-based electric vehicles.
KOGAS partnered with McDermott’s CB&I last year to explore large-scale liquid hydrogen storage in South Korea.
