Boryeong Station Fact Sheet: Carbon Dioxide Capture and Storage Project

Company/Alliance: Korea Electric Power Corporation (KEPCO)

Location: Boryeong Power Station (unit 8), South Korea

Feedstock: Coal

Size: 10 MW (slip-stream from 500MW unit)

Capture Technology: Post-combustion (KEPCO wet amine)

CO2 Fate: Vented

Timing: Operation started May 2013 for three years

Scale Up: Full Scale demonstration project by 2020

Motivation/Economics:

Estimated cost of the scale up project from 0.1 MW to 10 MW is US$42 million (2010-2014)

Comments:

This project initially started in October 2010 as a 0.1 MW test of the same amine capture process at the same site. After a successful operation, it was then expanded to its current 10MW size. KEPCO plans to scale-up the project into full size demonstration project by 2020.

KEPCO is using a proprietary solvent – KoSol-4 – in the Boryeong CCS pilot plant. CO2 capture is more than 90% with over 99% purity with this capture technology.

KEPCO is also testing other sorbents. At the KOSPO's Hadong Thermal Power Station in Hadong, Korea, a 0.5MW test of dry regerable sorbent started in 2010. The Hadong project in 2013 also scaled up to a 10MW slipstream at the same location testing the same absorbents.

The Korean Government has allocated US$1.74 billion for the demonstration of CCS in Korea and with this money it plans to have 2 demonstration projects in operation by 2020. US $1 billion from Government and US $0.74 billion from the private industry. The aim is that a new coal-fired power plant with CCS will take about 10-15% share in CO2 reduction by 2030.

The Korea Offshore CO2 Geological Storage Project from 2005-2015 has a budget of US$66 million to identify and locate suitable storage sites in offshore South Korea.
