Korea Gas Corp. (KOGAS) is kicking efforts into high gear to verify a hydrogen mixing technology to reduce greenhouse gas emissions, in accordance with international standards, and meet the government’s carbon neutrality goal.
KOGAS, charged with the responsibilities of stabilizing the supply of natural gas to houses and businesses, is shifting to becoming an eco-friendly energy entity with a focus on hydrogen.
KOGAS is to supply natural gas as mixed with hydrogen as part of ESG management.
Specifically, KOGAS, or general city gas operators, will build a hydrogen mixing facility at their static pressure facility to supply natural gas and hydrogen via the city gas pipe networks.
It means that mixing natural gas with hydrogen could lower greenhouse gas emissions.
Korea’s annual consumption of natural gas stands at 40 million tons. KOGAS estimates that mixing natural gas with hydrogen with 10 percent by would reduce natural gas use of 1.29 million tons.
It means CO2 emissions may be decreased by 3.55 million tons annually.
Hydrogen mixing before a hydrogen-only network is built is a nationwide, efficient hydrogen supply option. Supplying natural gas mixed with hydrogen via the city gas pipe networks will allow not only household gas boilers, gas stoves, industry boilers and compressed natural gas buses but also every device using city gas, such as gas turbines for power generation, to use hydrogen together.
Korea has launched a team comprising of KOGAS and Korea Gas Safety Corp. to verify the mixing of natural gas with hydrogen.
The government has come up with a stage-by-stage verification plan with the commercialization of city gas mixed with hydrogen at a 20 percent rate, increasing hydrogen demand to 1.07 million tons and reducing greenhouse gas emissions to 7.5 million tons.
KOGAS has begun to conduct verification case analyses related to overseas verification cases, build experimental facilities and develop verification operation technologies related to hydrogen mixing.
In March, KOGAS struck an MOU to cooperate in the development of green hydrogen pipeline hydrogen mixing technologies.
In May, KOGAS struck a MOU on technology consulting service on mixing and transiting hydrogen via city gas pipe network with DNV. DNV is an international accredited registrar and classification society headquartered in Høvik, Norway. DNV is implementing about 70 hydrogen projects in Europe and other areas.
Mixing natural gas with hydrogen and supplying it via the city gas pipeline network could reduce not only the consumption of gas, but will also cut down on greenhouse gas emissions.
Factors such as the characteristics of the texture of the pipeline, acceptance of surrounding facilities, and the safety of combustion facilities need to be taken into account.
KOGAS plans to explore improvement tasks by evaluating an impact on city gas pipeline according to hydrogen mixing density degrees (20 percent, 50 percent and 100 percent) with DNV down the road.
KOGAS aims to verify the commercializing of mixing hydrogen 20 percent by 2025 and later the corporation plans to implement changing natural gas pipelines for power plants into hydrogen-only networks to supply high-density hydrogen.
KOGAS Increases Hydrogen Supply Prices for Transportation Hydrogen Charging Stations
KOGAS, an institution specializing in the supply of hydrogen, announced a 12.2 percent rise in hydrogen gas prices compared to a first joint purchase price for nine hydrogen stations, including the Imam Gas Station in Gwangju, on Aug. 31.
The upward hydrogen price adjustment .is attributable to rising byproduct hydrogen purchase and hydrogen tube trailer transportation costs, coupled with a surge in crude prices and raw material prices, caused by Russia’s war with Ukraine.
KOGAS has had meetings with the central and local governments, public entities, hydrogen suppliers and charging station operators to discuss the operation of the sustainable transportation hydrogen market and formed a consensus on the inevitability of increasing hydrogen supply prices.
