Thirty-six miles off the coast of South Korea, the Donghae gas field is running dry. When it closes next year, its pipeline to the port of Ulsan could go into reverse, creating the Asian nation’s first major carbon-capture reservoir by injecting CO2 into the rock below the sea bed.
The plan is to store 400,000 tons of carbon dioxide emissions annually for 30 years from 2025, according to Korea National Oil Corp., which will run a feasibility study on the project this year. It would be South Korea’s first major carbon capture and storage (CCS) project and could become one of the biggest in the world.
