Challenges to the Carbon Dioxide Capture and Storage (CCS) Technology

Abstract

Carbon dioxide Capture and Storage (CCS) technology, which is one of the technologies against global warming, applied to the separation and capture of CO 2 gas and finally storage underground is attracting attention. There are several technologies being developed for CO 2 separation and capture, namely the chemical absorption method, physical absorption method, adsorbing separation method and membrane separation method. These are being developed to apply to postcombustion capture, oxyfuel postcombustion capture, etc. With regard to the CO 2 storage technologies, the method of injection into an aquifer is being developed as the major one, and studies on issues for actual technical application are being conducted in the form of engineering study on the assumed model area. In this report, our expectations toward actual application of the CCS technology, the trends of the CCS technology and other related matters are introduced. 

Integrated gasification combined cycle (IGCC) systems

“…As a result, it is not emitted to the atmosphere. Carbon capture technologies have been established and utilized in the chemical industry, for example, urea synthesis (Murai and Fujioka, 2008 ). A large-scale CCS project has been demonstrated in Canada since September 2000.…”

Comparison of absorption rates and absorption capacity of ammonia solvents with MEA and MDEA aqueous blends for CO2 capture

“…However, MEA presents some important disadvantages, such as low absorption capacity limited at 0.4 kg of CO 2 per kg of absorbent (Williams, 2006), it is highly corrosive and its absorption performance is strongly degraded when SO 2 , NO 2 , HCl, HF and O 2 are present in the exhaust gas. For this last issue, carbon capture by MEA aqueous solutions requires several pretreatment steps in order to eliminate undesirable chemical compounds, which leads to high capture costs estimated at around 60$/tonne of CO 2 (Murai and Fujioka, 2008). Finally, the stripping stage of MEA aqueous solutions (desorption) requires important amounts of energy to regenerate the solvent and free the CO 2 captured.…”

Study on the Seepage and Stability of Carbon Dioxide Geological Storage in Scrap Metal Mine: A Finite Difference Analysis

“…Many scholars in the world have put forward huge constructive methods and technology. Murai and Fujioka discussed the challenges to the carbon dioxide capture and storage (CCS) technology and listed the issues for actual technical application in the engineering [1]. Herzog scaled up the carbon dioxide capture and storage from megatons to gigatons [2].…”
