“…However, the reduction rate over the whole life cycle of only 59 to 60% may call into question the benefits of the huge investments that would be required for the deployment of a comprehensive CCS infrastructure in China. This rate is 14 percentage points lower than that calculated for India [6], mainly due to high coalbed methane emissions. Furthermore, it is presumed here that there would be no leakages at the storage sites.…”

“…This could lead to the conclusion being drawn that the cost barrier that needs to be overcome to achieve the economic viability of CCS plants is significantly lower in China than in industrialised countries. However, even in other emerging economies such as India [6], specific ambient conditions lead to higher plant investment costs.…”

Objective The aim of the present article is to conduct an integrated assessment in order to explore whether CCS could be a viable technological option for significantly reducing future CO 2 emissions in China.Methods In this paper, an integrated approach covering five assessment dimensions is chosen.Each dimension is investigated using specific methods (graphical abstract). ResultsThe most crucial precondition that must be met is a reliable storage capacity assessment based on site-specific geological data. Our projection of different trends of coal-based power plant capacities up to 2050 ranges between 34 and 221 Gt of CO 2 that may be captured from coal-fired power plants to be built by 2050. If very optimistic assumptions about the country's CO 2 storage potential are applied, 192 Gt of CO 2 could theoretically be stored as a result of matching these sources with suitable sinks. If a cautious approach is taken, this figure falls to 29 Gt of CO 2 . In practice, this potential will decrease further with the impact of technical, legal, economic and social acceptance factors. Further constraints may be the delayed commercial availability of CCS in China; a significant barrier to achieving the economic viability of CCS due to a currently non-existing nation-wide CO 2 pricing scheme that generates a sufficiently strong price signal; an expected life-cycle reduction rate of the power plant's greenhouse gas emissions of 59 to 60%; and an increase in most other negative environmental and social impacts. Conclusion and practice implicationsMost experts expect a striking dominance of coal-fired power generation in the country's electricity sector, even if the recent trend towards a flattened deployment of coal capacity and reduced annual growth rates of coal-fired generation proves to be true in the future. In order to reduce fossil fuel-related CO 2 emissions to a level that would be consistent with the long-term climate protection target of the international community to

Life cycle assessment of carbon capture and storage in saline aquifers for coal‐fired power generation: An Indian scenario

2022

Human activity is causing an increase in the atmospheric concentration of greenhouse gases (GHGs) resulting in global climate change. The use of carbon capture and storage (CCS) in energy supply systems is one method of reducing GHG emissions. Three pulverized coal‐fired power stations near the Krishna–Godavari basin with and without CCS have been evaluated using the life cycle assessment and economical approach. Mono‐ethanolamine (MEA) postcombustion CO2 capture, compression, transportation with the pipeline, and storage in the Krishna–Godavari basin are all part of the CCS system. Up to 89% of power plants’ CO2 emissions can potentially be reduced. The retrofitting of a CO2 capture unit into a power plant adds the most to emissions and the cost of the CCS system. There is a 66% rise in the electricity cost when CCS is implemented in an existing power station, with a capital cost of about US$3.4billion. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
