Process modelling and techno-economic analysis of natural gas combined cycle integrated with calcium looping
Calcium looping (CaL) is promising for large-scale CO2 capture in the power generation and industrial sectors due to the cheap sorbent used and the relatively low energy penalties achieved with this process. Because of the high operating temperatures the heat utilisation is a major advantag...

description |
Calcium looping (CaL) is promising for large-scale CO2 capture in the power
generation and industrial sectors due to the cheap sorbent used and the
relatively low energy penalties achieved with this process. Because of the
high operating temperatures the heat utilisation is a major advantage of the
process, since a significant amount of power can be generated from it.
However, this increases its complexity and capital costs. Therefore, not only
the energy efficiency performance is important for these cycles, but also the
capital costs must be taken into account, i.e. techno-economic analyses are
required in order to determine which parameters and configurations are
optimal to enhance technology viability in different integration scenarios.
In this study the integration scenarios of CaL cycles and natural gas
combined cycles (NGCC) are explored. The process models of the NGCC and CaL
capture plant are developed to explore the most promising scenarios for
NGCC-CaL integration with regards to efficiency penalties. Two scenarios are
analysed in detail, and show that the system with heat recovery steam
generator (HRSG) before and after the capture plant exhibited better
performance of 49.1% efficiency compared with that of 45.7% when only one
HRSG is located after the capture plant. However, the techno-economic
analyses showed that the more energy efficient case, with two HRSGs, implies
relatively higher cost of electricity (COE), 44.1€/MWh, when compared to that
of the reference plant system (33.1€/MWh). The predicted cost of CO2 avoided
for the case with two HRSGS is 29.3 €/ton CO2. |
