Achieving peak carbon dioxide emissions and accelerating decarbonization progress in the power industry is of paramount significance to Henan Province's objective of achieving carbon peak and neutrality. In this study, the Carbon Emission-Energy Integrated Model (iCEM) was employed to conduct scenario studies on the coal reduction and carbon reduction paths under the "dual-carbon" goal of Henan's power industry. The results indicated that, by considering measures such as optimizing the power source structure and technological progress, Henan Province's power industry carbon emissions will reach their peak between 2028-2033, with coal consumption in the power industry continuing to grow during the "14th Five-Year Plan" period. With a peak range between 2027-2031, the peak value increased by 1881, 1592, and 11.48 million tce, respectively, compared with that in 2020. To control coal in Henan Province under the constraint of carbon peak goals, it is proposed to develop clean energy sources such as wind and solar power, use more low-carbon or zero-carbon heat sources, increase the proportion of external electricity supply, and enhance energy-saving transformation in coal-fired power plants. Accelerating the elimination of backward units and energy-saving transformation of existing units, accelerating non-fossil energy development, advanced planning for external electricity supply, improving market mechanisms for the exit of coal-fired power plants and peak regulation, increasing system flexibility, and accelerating external policies to ensure clean energy security are effective paths for controlling coal and reducing carbon emissions in Henan's power industry. Additionally, inland nuclear power layout is one of the crucial paths to alleviate coal control pressure in Henan Province and achieve "dual-carbon" goals during the carbon-neutral stage. Therefore, it is imperative to conduct research on demonstrations in advance. Henan Province is highly dependent on energy from other provinces, and the power supply and demand situation in Henan Province will become increasingly tense in the future. It is necessary to support Henan Province from the State Grid and coordinate the construction of inter-provincial and inter-regional power transmission channels.
实现电力行业二氧化碳排放达峰并加速脱碳进程,对河南省实现碳达峰、碳中和目标至关重要。本研究采用碳排放-能源综合模型(iCEM),对河南电力行业“双碳”目标下的降煤减碳路径进行情景研究。结果表明,通过优化电源结构、技术进步等措施,河南省电力行业碳排放将于2028-2033年达峰,“十四五”期间电力行业煤炭消费仍将增长。峰值范围在2027-2031年,峰值较2020年分别增加1881、1592和1148万吨标准煤。为在碳达峰目标约束下控制河南煤炭消费,建议发展风能、太阳能等清洁能源,采用更多低碳或零碳热源,提高省外来电比例,加强燃煤电厂节能改造。加速淘汰落后机组和现有机组节能改造,加快非化石能源发展,提前规划省外来电,完善燃煤电厂退出和调峰市场机制,提高系统灵活性,加快出台保障清洁能源安全的外部政策,是河南电力行业控煤减碳的有效途径。此外,内陆核电布局是缓解河南省控煤压力、实现碳中和阶段“双碳”目标的关键路径之一,因此必须提前开展示范研究。河南省能源对外省依赖度高,未来河南省电力供需形势将日益紧张,有必要由国家电网给予支持,统筹建设省间和区域间输电通道。
