Cost-benefit analysis of carbon dioxide capture and storage considering the impact of two different climate change mitigation regimes

This study examines a typical decision-making process aimed at assessing the merits of constructing a new coal-fired power plant with three possible investment options: two with different Carbon Dioxide Capture and Storage (CCS) plants and one without. A Costs-Benefits Analysis (CBA) is carried out considering that the industrial investment may be affected by two alternative climate change mitigation regimes. The results show the impact of specific climate change mitigation regimes on the balance between the financial value and the socio-economic implications of investment in a CCS oxy-combustion or post-combustion plant. Therefore, this study aims to define which CCS plant option is the optimal investment choice that could be considered a financial and socio-economically sustainable climate change strategy.
