“The TEA of CO2 capturing technology is important for the feasibility of the setup of the facility. A few researchers (Singh, Croiset et al. 2003, Schach, Schneider et al. 2010, Husebye, Brunsvold et al. 2012, Roussanaly, Brunsvold et al. 2013, Ali, Agbonghae et al. 2016, Li, Leigh et al. 2016, Hu, Xu et al. 2017, Rolfe, Huang et al. 2017, van der Spek, Sanchez Fernandez et al. 2017, Cau, Tola et al. 2018, Rolfe, Huang et al. 2018) have investigated the cost of CO2 capture and retrofitting in coal or natural gas-fired power plants using different methods like amine scrubbing or combustion with pure oxygen and recycling of flue gas. A cost summary from various researches including federal and academic institutes is shown in Table 1.
Table 1. Cost Comparison for CO2 Capturing and Unit Retrofitting
Type of Plant | Method | Cost ($/ton of CO2) | References |
---|---|---|---|
Coal-fired | MEA scrubbing | 53 | (Singh, Croiset et al. 2003) |
Coal-fired | O2/CO2 recycle combustion | 35 | (Singh, Croiset et al. 2003) |
– | MEA scrubbing | 32-76 | (Roussanaly, Brunsvold et al. 2013) |
Coal-fired | MEA scrubbing | 75.1 | (Li, Leigh et al. 2016) |
NGCC | MEA scrubbing | 92 | (DOE-NETL 2007) |
NGCC | MEA scrubbing | 83 | (DOE-NETL 2010) |
NGCC | MEA scrubbing | 74 | (Rubin and Zhai 2012) |
NGCC | MEA scrubbing | 95 | (EPRI 2009) |
NGCC | MEA scrubbing | 114 | (DOE 2010) |
The CO2 capture cost including the retrofitting to the power plant depends on various factors such as location, type of power plant, compositions of the flue gas, capture technology, capture amount and the ability of the power plant to supply utilities that are required in capturing unit.
