Heriot-Watt University's Research Gateway provides an overview of current status of carbon dioxide capture and storage technologies. The paper, published in Renewable and Sustainable Energy Reviews, discusses various aspects of carbon dioxide capture and storage (CCS), including capture, separation, transport, storage, leakage, monitoring, and life cycle analysis. The selection of specific CO₂ capture technology depends on the type of CO₂ generating plant and fuel used. Among those CO₂ separation processes, absorption is the most mature and commonly adopted due to its higher efficiency and lower cost. Pipeline is considered to be the most viable solution for large volume of CO₂ transport. Among those geological formations for CO₂ storage, enhanced oil recovery is mature and has been practiced for many years but its economical viability for anthropogenic sources needs to be demonstrated. There are growing interests in CO₂ storage in saline aquifers due to their enormous potential storage capacity and several projects are in the pipeline for demonstration of its viability. There are multiple hurdles to CCS deployment including the absence of a clear business case for CCS investment and the absence of robust economic incentives to support the additional high capital and operating costs of the whole CCS process. The paper also discusses various CO₂ capture technologies, including post-combustion, pre-combustion, and oxyfuel combustion. It compares the different combustion technologies for CO₂ capture and discusses the various separation technologies, including absorption, adsorption, chemical looping combustion, membrane separation, hydrate-based separation, and cryogenic distillation. The paper also discusses CO₂ transport, utilization, geological storage, and the barriers and opportunities for commercial deployment of CCS. The paper concludes that CCS is a crucial strategy for meeting CO₂ emission reduction targets and that further research and development are needed to overcome the challenges associated with CCS deployment.Heriot-Watt University's Research Gateway provides an overview of current status of carbon dioxide capture and storage technologies.
