Techno-economic evaluation of CO2 transport from a lignite-fired IGCC plant in the Czech Republic
چکیده انگلیسی
In addition, further assessments are performed to evaluate the impact of impurities in the CO2 streams from the capture plant on the CO2 conditioning and transport costs for the four combinations of transport scenarios and technology options. The results show that the impurities present in the CO2 streams lead to increases in CO2 conditioning and transport costs ranging from 1.6 to 11.4% (0.2-1.9 €/tCO2). However, the energy and cost impacts associated with the impurities are highly dependent on the transport technology and transport delivery location scenario considered. Furthermore, the process energy and cost performances of two alternative CO2 liquefaction processes, designed to reduce CO2 losses through the purged gas, are also evaluated. These two alternative processes result in higher CO2 conditioning cost than the base case process, which suggests that reducing the CO2 losses compared to the base case would not be a good strategy, unless high costs (70-110 €/tCO2) were spent to capture the CO2 that is purged. Finally, the potential of train-based transport is evaluated beyond the four cases considered by comparing the CO2 conditioning and transport costs of pipeline and train transports as a function of the distance for different train conditioning cost scenarios and different project economic valuation periods. The results show that train-based transport could potentially be a cost-optimal alternative to pipeline-based transport for medium to long distances especially in cases where the additional conditioning costs of train-based transport compared to pipeline are limited, or in cases of financial risk-averse decisions.
