Implication

System optimization modeling demonstrates a three-phase decarbonization pathway across 31 provinces, indicating regional resource coordination drives cost-effective industrial abatement.

Key Points

Evaluate cost-effective, spatially explicit deep decarbonization pathways for China's cement sector from 2025 to 2060 under dynamic policy and renewable energy constraints.
Developed a high-resolution whole-system optimization framework covering 31 mainland provinces from 2025 to 2060.
Evaluated competing routes including methane reforming, carbon capture and storage (CCS), and hydrogen-based carbon capture and utilization (CCU) alongside inter-provincial clinker and CO2 logistics.
Decarbonization achieves optimal cost-efficiency via a three-phase transition where CCS serves as a bridging mechanism before hydrogen-based CCU becomes competitive post-2052.
An interim emissions benchmark of approximately 400 Mt CO2 by 2040 is facilitated by inter-provincial clinker and CO2 transport from renewable-rich to demand-heavy regions.
Accelerating mitigation requires carbon-price growth exceeding 25 CNY/ton (3.5 USD/ton) CO2 per year, while hydrogen-based CCU adoption requires methanol prices above 2750 CNY/ton (382 USD/ton).
