Abstract

This study develops an hourly power system simulation model for China, considering high-resolution geological constraints for carbon-capture utilization and storage (CCUS) to explore optimal solutions for a reliable and resilient near-zero power system. Simulating 10,450 scenarios with varying electricity storage durations, interprovincial transmission capacities, and shares of abated fossil power with CCUS, the study finds that allowing up to 20% abated fossil fuel power generation could significantly reduce power shortages. A lowest-cost scenario with 16% abated fossil fuel power generation even reduces investment costs and enhances system resilience during extreme weather events.
