摘要

中国煤电系统面临高碳排与可再生能源并网波动双重挑战。传统碳捕集、利用与封存（CCUS）技术虽具备规模化减排潜力，但存在成本高、能耗密集且挤占调峰空间等瓶颈，制约其工程化应用。钙循环技术兼具储能与碳捕集双重功能，结合时序用能优化可实现低碳导向下的高效调峰。本研究以600 MWe超临界机组为对象，构建CCS/CCU连续与间歇四种工艺，评估其质能平衡与技术经济性。结果表明：间歇运行相较于连续运行总投资增加24%~27%，但谷电策略大幅降低能耗成本，CCS-间歇与CCU-间歇单位减排成本较连续模式分别降低58%与43%。CCS-间歇工艺在峰谷电时段的电能输出功率分别达670.78 MWe与268.67 MWe，同步实现高效碳捕集与超300 MWe弹性调峰，为煤电低碳灵活转型提供可行路径。

Abstract

In the context of global efforts to address climate change and energy transition

the energy structure of China

which is dominated by coal power

faces challenges from the inherent high carbon emissions of coal-fired plants and the intermittency issues caused by the large-scale integration of renewable energy. Although traditional carbon capture

utilization

and storage (CCUS) technologies can reduce emissions

their continuous high energy consumption competes for valuable power regulation capacity during peak demand periods

while high operating costs further hinder large-scale deployment. To simultaneously address carbon reduction and grid peak load regulation

this paper proposes a calcium-looping CCUS system integrated with grid peak shaving. The core innovation lies in optimizing the temporal allocation of energy consumption. During peak electricity demand periods

the system primarily operates the carbonation reaction to capture CO

from flue gas

utilizing the reaction heat to assist in power generation

thereby meeting peak output demand and supporting the peak shaving capability of the plant. During off-peak hours at night

the system utilizes low-cost surplus energy (valley electricity) to drive the energy-intensive calcination for sorbent regeneration and subsequent processing. This design enables coal-fired power plants to effectively reduce carbon emissions while maintaining baseload power supply. In this paper

a 600 MWe supercritical coal-fired unit was used as the reference to respectively construct CCS-continuous

CCU-continu

ous

CCS-intermittent

and CCU-intermittent process flows. Based on the Aspen Plus® platform

the study simulated the material and energy balances of each process and evaluated their technical and economic feasibility. The results show that although the intermittent operation mode requires a total investment 24% higher than that of the continuous mode due to additional storage tanks and equipment

its strategy of fully utilizing valley electricity offers a disruptive cost advantage. The unit carbon emission reduction cost of CCS-intermittent and CCU-intermittent is over 58% and 43% lower than that of their continuous mode. Using the CCS-intermittent process

the power plant can output a net power of 670.78 MWe during peak periods and 268.67 MWe during off-peak periods

while simultaneously achieving carbon capture

demonstrating a peak-shaving capacity of over 300 MWe.
