DNV to assess the viability of blending hydrogen into South Korea's gas transmission network
DNV has been selected by South Korea’s state-owned natural gas importer and transporter Korea Gas Corporation (KOGAS) to assess the viability of blending hydrogen into the nation’s gas transmission network.
KOGAS is the world’s largest importer of liquefied natural gas (LNG) and transports the regasified fuel nationwide through its extensive high-pressure gas pipeline network.
The two-year project will assess the scope for blending hydrogen with natural gas in KOGAS’ 5,000-kilometre-long domestic transmission network. More specifically, DNV will assess the pipeline network’s suitability for hydrogen blending, provide technical and advisory support to KOGAS’s hydrogen blending test project on Jeju Island and provide support to KOGAS in addressing the requirements of South Korea’s regulatory authorities in overseeing hydrogen’s integration and uptake.
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, construction and operation of hydrogen injection facilities and equipment, reviewing methods for controlling the concentration of hydrogen blending for customers, providing on-site technical support and data analysis for the hydrogen demonstration project and supporting KOGAS in addressing the requirements of the energy regulator through the application of knowledge gained in related projects internationally.
DNV is working globally with an increasing number of gas pipeline companies to safely repurpose gas transmission and distribution networks for the integration of blended and 100% hydrogen gas. In addition, DNV’s Spadeadam research facility in the UK is conducting full-scale testing on the safe transportation of hydrogen in gas networks through to the appliances in homes.
Using imported LNG, natural gas is responsible for around 26% of South Korea’s power generation capacity, a share expected to grow to 31% by 2050 as coal and nuclear plants are phased out in accordance with South Korea’s 2050 Carbon Neutral Strategy and 9th Electricity Plan.
South Korea adopted the Hydrogen Economy Roadmap in 2019 and established the Hydrogen Economy Commission in 2021 to oversee the development of a fully-fledged hydrogen economy to decarbonize transport, power generation and industry while also driving economic growth and global industrial competitiveness.
Up to 2040, KOGAS is planning to invest $37 billion internationally to establish renewable power generation facilities that produce hydrogen which will be imported, stored and transported through a specialized hydrogen pipeline network.
South Korea sees hydrogen as a potential driver of job creation and economic growth worth 43 trillion won ($43 billion). It is targeting hydrogen use to grow from 5.26 million tons per annum (Mtpa) at present to over 130,000 Mtpa by 2040, helping to develop large-scale stationary fuel cell power generation facilities and fuel cell electric vehicles (FCEVs).
South Korea has the highest share of industrial energy demand of all IEA member countries at 55% and the third-largest public investment in hydrogen after Germany and Japan. Hydrogen blending will support the decarbonization of South Korea’s manufacturing sector and is the backbone of the nation’s national hydrogen strategy.
