The Korean Electric Power Corporation (KEPCO) is developing plans for a 500MW oxyfuel combustion, or IGCC with pre-combustion capture, to be located at either Samcheonpo or Taean in South Korea.
If realised, the project would aim to capture 1.2 million tonnes per annum of CO2, which would be transported by ship for storage offshore in deep saline formations. It is intended that at least 1Mtpa would be stored from 2019, and the plant would operate for around thirty years.
A survey of three to four potential saline formation storage sites is being conducted by industry and various government ministries, including Ulleung saline aquifer and Gorae gas reservoir. The Korean Ministry of Land, Transport, and Maritime affairs has announced the discovery of an offshore formation capable of holding around 5 billion tonnes of CO2, which could potentially serve CCS1 and CCS2.
Coal consumption accounts for 43.5% of South Korea’s fossil fuel CO2 emissions. In April 2010, South Korea brought its Basic Law on Low-Carbon GreenGrowth into force, which is hoped to boost the progress of CCS within the country. Korea-CCS2 is one of two demonstration projects currently being considered by the Korean government. See Timing below.
The government is also proposing a project to demonstrate post-combustion capture technology, which would capture up to 1.2Mtpa of CO2 from a 300MW coal power plant. A pre-feasibility study began in 2009. Injection start-up is planned in 2017. The project has been identified by the Global CCS Institute and by the International Energy Agency’s 2010 CCS progress report. All other details are confidential.
Korea-CCS2 has received government funding but project cost details are not available. However, CCS is known to fall within 17 of the country’s new areas of national growth.
The proposed CCS2 project is in the early stages of development and is dependent on the state choosing the capture technology to pursue. The government aims to have two demonstration projects up and running by 2014 with two commercial-scale plants operating by 2020.
