Overall environmental impacts of CCS technologies—A life cycle approach

Comparison of CO2 Capture Approaches for Fossil-Based Power Generation: Review and Meta-Study

“…For example, one study found that adding post-combustion solvent-based CO 2 capture to a classic pulverized coal power plant caused the average levelized cost of electricity (LCOE) to increase by 50-90% [20]. This means that, although the capture system may recover about 90% of the CO 2 actually generated by the facility, the average lifecycle GHG emissions reduction of the plants surveyed in this work is only in the range of 65-71%, which compares well to reported ranges of 50-75% in other studies [21][22][23].…”

“…Moreover, because the fuel use is so much higher, adding CO 2 capture to a combustion-based power plant makes the environmental impacts as much as 10-67% worse in many other kinds of environmental impact categories [21,22]. For example, one life cycle analysis study concluded that adding post-combustion capture to a coal combustion power plant causes 38% more fossil fuel consumption, 46% more toxicity impacts in humans, 58-59% more toxicity in freshwater, marine, and land-based ecosystems, and 67% more freshwater depletion [22].…”

Life cycle assessment demonstrates environmental co-benefits and trade-offs of low-carbon electricity supply options

“…This effect is large enough to result in life cycle GHG emissions of a natural gas power plant with CCS being comparable to those of coal-fired systems with CCS. The assumed rate of fugitive emissions in the natural gas chain is larger in our assessment than previously assumed due to new evidence on methane emissions from the natural gas system (58,94). Fugitive natural gas emissions across the supply chain are an important factor in determining life cycle GHG emissions, but the state of the science is not yet conclusive regarding either the magnitude of these emissions or how much they might differ by location and type of gas resource (61,95).…”

A Modified D Numbers Methodology for Environmental Impact Assessment

“…EIA problem is an identification of many factors involved in both harmful and beneficial about the project should be put into effect or which plan should be chosen in the decision making system. Some previous studies show the EIA framework has been developed in many fields (De Boer 2003;Lenzen et al 2003;Dreyer et al 2006;Wang et al 2006;Kiliç et al 2011;Zapp et al 2012;Sueyoshi, Goto 2012;Bigum et al 2012;Xu et al 2014;Jordan et al 2014;Zavadskas et al 2015) and many methods are applied in EIA such as Life cycle assessment (Tukker 2000;Riga et al 2015), group decision-making methods (Rikhtegar et al 2014) and so on (Miao et al 2014;Ma et al 2014;Ni et al 2014). In the real world, many potential environment assessment factors cannot be quantified accurately, they are qualitative or linguistic forms which lead to uncertainty, fuzziness and incompleteness.…”
