Recent Developments

• In February 2025, the Act on the Capture, Transport, Storage and Utilization of Carbon Dioxide came into effect in South Korea, establishing a legal and institutional framework for the development of CCUS technologies, including CO₂ injection and utilization applications. The legislation is expected to support investment and commercialization of carbon management technologies in South Korea.
• In 2025, Korea National Oil Corporation (KNOC) continued preparations for the Donghae-1 depleted gas field CCS demonstration project, which aims to inject approximately 1.2 million tonnes of CO₂ annually into the offshore reservoir. The project supports the development of CO₂ injection, monitoring, and geological storage technologies in South Korea.
• In November 2025, Korean researchers presented studies on CO₂-EOR and CO₂ storage at the Fall Joint Conference of Korean resource and petroleum engineering societies. The research evaluated different CO₂ injection scenarios for improving oil recovery while increasing long-term CO₂ retention, supporting the development of integrated EOR and carbon-storage technologies.

Expert Views

Experts believe that South Korea’s CO₂ EOR market will grow gradually rather than rapidly. The country has strong energy, chemical, engineering, and manufacturing capabilities, but limited domestic oil production restricts the size of the local EOR opportunity.

The strongest future potential is likely to come from the integration of CO₂ EOR with CCUS. This approach may support oil recovery while also creating a use or storage pathway for captured carbon.

Experts also identify major risks, including high capital expenditure, uncertain oil prices, limited suitable reservoirs, environmental approval, and the cost of transporting CO₂. Government incentives, carbon pricing, and international cooperation will be important for commercial development.
