A comprehensive review on CO2 capture and storage (CCS) technology in global scenario.

Due to increasing concentrations of anthropogenic carbon dioxide in the atmosphere, the problem of climate change due to global warming is becoming biggest concern. According to latest report of Intergovernmental Panel on Climate Change (IPCC), it is indicated that to constraint warming at 1.5 oC, global anthropogenic CO2 emissions would need to minimized by 45% till 2030 from 2010 levels and become net zero by 2050. One way to do this is by reducing the concentration of carbon dioxide from the atmosphere. The promising technology which could reduce CO2 concentrations from the atmosphere is the CO2 capture and storage (CCS) technology. The CCS technology involves the method of capturing effluent CO2 emitted on large scale from sources like power stations and prevent it from entering into atmosphere. Further, the captured CO2 is stored in subsurface geological formations from where it is transported to the desired site through pipelines, ships etc. for industrial and Enhanced Oil Recovery process (EOR). Low level of experience and awareness about technology in society negatively impact the successful deployment CCS projects. It is recognized that renewable power (such as wind, solar, etc.) represents only one element of technologies that will be required to deliver a technically and economically feasible energy system. In this context, CCS is known to play a vital role, providing significant value through flexible operation. However, despite of wide applications and its technical advantages, CCS has not yet been implemented on a larger scale with the ambitions formed a decade ago. This paper aims to review the importance of CCS projects in the global scenario by understanding various advantages that this technology offers to the people and various factors like environmental, technical, social and economic factors affecting the implementation of CCS technology which will describe the feasibility of this technology on a larger scale in the particular region about which was thought nearly a decade ago.
