These metrics position post-combustion as the option best suited for economic viability. However, it also has the highest CEI of 0.15 tCO2
This paper evaluates the feasibility of implementing post-combustion carbon capture, storage, and utilization (CCSU) technologies in NGCC power plants
Conclusion The economic analysis shows that the static investment cost of the integrated plant is 54.28% higher than that of the single power plant, and the
Post-combustion carbon capture (PCC) is a promising way to decarbonize the natural gas combined cycle (NGCC). However, capturing CO2 from the
This study evaluated different post combustion capture process modifications for SCPC and NGCC power plant. * Post combustion capture process improvements that are already well established such as intercooling in the absorber and improved heat integration with power plant, combined with improved solvents typical of those that are expected to become available by 2020, should substantially reduce the efficiency penalty on power plant. * Current stage of process design improvements and improvements in solvent properties leads to reducing efficiency penalty from 9.8% to 6.11% for super critical pulverised coal (SCPC) fired power plant with amine based solvent CO2 capture process base case. * Overall it can be noticed from this study that once all current improvements have been implemented in the solvent based post combustion capture process, different process modifications for SCPC and NGCC only bring slight improvements in the power plant efficiency penalty. * The performance and cost of different post combustion capture process modifications depend on the type of solvent used.
The main goal was to improve the flexibility and efficiency of carbon capture operations based on different electricity demands and flue gas conditions.
This report presents an Electric Power Research Institute (EPRI) assessment on the technical feasibility, performance, and associated costs of applying post-
This work aims to analyze the cost projection of natural gas combined cycles (NGCC) with post-combustion carbon capture (PCC) technology for two promising power plant configurations, namely: conventional NGCC and exhaust gas recirculation (EGR). Twelve study cases were evaluated in this work: Conventional NGCC (NGCC) and NGCC with exhaust gas recirculation (EGR), considering two technological maturity statuses, FOAK and NOAK plants, at different carbon capture levels (see Table 1). Capital cost for conventional NGCC power plant with PCC technology by type of plant (FOAK and NOAK) at different capture levels. Capital cost for EGR power plant with PCC technology by type of plant (FOAK and NOAK) at different capture levels. For example, for a conventional NGCC plant with a 90% carbon capture rate (NF-90%), the BAU value for a FOAK plant is $169.0/tCO2 compared to the $132.4/tCO2 for a NOAK plant (NN-90%), which represents a cost reduction equal of 21.6% (see Supplementary Table S5 in the Supplementary Information section).
