dc.description.abstractCalcium looping combustion (CaLC), which comprises an indirectly-heated calciner, is characterised with lower energy intensity and economic penalties compared to that of mature CO2 capture technologies. As CaLC is a standalone power boiler, integration of advanced power cycles can lead to further improvement in net efficiency and reduction in the cost of electricity. Therefore, this study aimed to propose routes for the integration of the supercritical CO2 cycle (sCO2) with CaLC and to evaluate their benefits with respect to the conventional steam cycle. Such processes were modelled in Aspen PlusTM. Moreover, the effect of the operating conditions on the techno-economic performance of the considered cases was evaluated. This study has shown that implementation of the optimised recompression sCO2 cycle with a clean gas cooler resulted in the net efficiency and break-even price of electricity of 37.3%HHV and 75.13 €/MWh, respectively. These are 0.7%HHV points lower and 26% higher, respectively, than that of the conventional coal-fired power plant without CO2 capture. Such performance, however, is superior to retrofits of coal-fired power plants with mature CO2 capture technologies as well as CaLC with a conventional steam cycle, proving the benefits of linking CaLC with advanced power cycles.en_UK
