摘要
逐步增强的稳定性和低碳化双重要求,决定了清洁煤电配套碳捕集、利用与封存(CCUS)和新能源发电配套储能成为我国电力领域未来发展的必然趋势.本文系统调研分析国内外清洁煤电、CCUS、新能源发电、储能等典型案例,研判技术发展趋势;采用涵盖全生命周期的平准化度电成本模型,测算现阶段、技术突破、商业化规模化3个阶段"清洁煤电+CCUS"的经济性及其变化,并从经济性、稳定性、安全性3个维度与"新能源+储能"进行对比分析,评估"清洁煤电+CCUS"的竞争力.分析表明:技术突破、CCUS商业化规模化将推动"清洁煤电+CCUS"成本降低30.3%～77.6%;当CCUS成本低于550元/t CO2时,"清洁煤电+CCUS"相比"新能源+储能"更有竞争力;当CCUS成本低于150元/t CO2时,"清洁煤电+CCUS"成本将低于"新能源+储能".基于二者的竞争性和协同性,测算分析了"清洁煤电+CCUS"的优势技术路线和应用场景.围绕提升清洁煤电的互补性、增强"清洁煤电+CCUS"的竞争性、推进煤电与新能源优化组合发展等方面,提出了零碳清洁煤电突破方向与技术路径:明确优先发展技术路线,加强变革性、颠覆性技术研发,提升清洁煤电机组调峰能力,促进煤电与新能源耦合协同发展,构建高端复合人才支撑体系.
Abstract
Considering the dual requirements of stability and low carbon,integrating clean coal power with carbon capture,utilization and storage(CCUS)and combining new energy power generation with energy storage have become the inevitable trends of China's power industry.This study investigates the typical cases regarding clean coal power,CCUS,new energy power generation,and energy storage in China and abroad,analyzing the trend of technological development.A levelling cost model is used to measure the economical efficiency and changes of"clean coal power+CCUS"in three stages:current stage,technological breakthroughs,and commercial application.The competitiveness of"clean coal power+CCUS"is evaluated by comparing it with the"new energy+energy storage"mode from three dimensions:economical efficiency,stability,and security.The results indicate that technological breakthroughs and commercialization of CCUS will reduce the cost of"clean coal power+CCUS"by 30.3%-77.6%.When the cost of CCUS is lower than 550 CNY/t CO2,"clean coal power+CCUS"is more competitive than the"new energy+energy storage"mode.When the cost of CCUS is lower than 150 CNY/t CO2,the cost of"clean coal power+CCUS"will be lower than that of"new energy+energy storage".Moreover,advantageous technical routes and application scenarios of"clean coal power+CCUS"are calculated and analyzed based on the competitiveness and synergy of"clean coal power+CCUS"and"new energy+energy storage".The breakthrough directions and technical path of zero-carbon clean coal power are proposed from the aspects of improving the complementarity of clean coal power,enhancing the competitiveness of"clean coal power+CCUS",and promoting the optimal combination of coal power and new energy.Furthermore,the following suggestions are proposed to promote the development of low-carbon clean coal:(1)clarifying the preferential technology route,(2)strengthening the research and development of transformative and disruptive technologies,(3)improving the peak shaving capability of clean coal-fired power units,(4)promoting the coupling and coordinated development of coal-fired power and new energy,and(5)establishing a high-end composite talent support system.
