 This study develops an hourly power system simulation model to explore the optimal solution for a reliable and resilient near-zero power system in China, considering high-resolution geological constraints for carbon capture utilization and storage. The results show that allowing up to 20% abetted fossil fuel power generation in the power system could reduce the national total power shortage rate by up to 9.0% in 2050 compared with a zero-fossil fuel system and also increase system resilience by reducing power shortage during extreme climatic events.
