摘要:

碳捕集与封存(CCS)及利用是实现CO2近零排放和碳中和目标的重要途径,但碳捕集成本和能耗的增加,使得系统能效降低。低能耗碳捕集技术的创新发展和高效可再生能源辅助碳捕集技术,是降低碳捕集能耗和提高系统能效的重要路径。总结了可再生能源与余热及其协同辅助碳捕集技术的类型和发展,综述分析了可再生能源中太阳能、地热能、风能、生物质能和余热以及多能耦合辅助碳捕集技术的最新进展及面临的主要问题,展望了未来利用可再生能源和余热辅助碳捕集技术的发展趋势。研究表明,随着可再生能源与余热开发利用技术的创新与发展,碳捕集成本降低的同时系统能效得到提高;综合利用和匹配太阳能制冷、热、电、光和化学转化辅助碳捕集技术,高效利用太阳能的潜力更大;可再生能源与余热及多能耦合辅助碳捕集,需重点研究工艺匹配、能量梯级优化利用,且综合评价与指标体系有待完善。

Abstract:

Carbon capture and storage technology(CCS)and its utilization are important for achieving near-zero CO2 emissions and carbon neutrality.However,the boost of cost and energy consumption of carbon capture will lower the energy efficiency of power systems.The innovation of low-energy carbon capture technology and development of carbon capture technology assisted by high-efficiency renewable energy are important ways to reduce the energy consumption in carbon capture and improve the energy efficiency of the system.The technologies of using renewable energy,waste heat and the combination of them to assist carbon capture are summarized.The status quo and problems of carbon capture technologies assisted by solar energy,wind energy,biomass energy,waste heat and multi-energy combination are analyzed and their development trends are foreseen.The review indicates that,with the innovation and development of renewable energy and waste heat utilization,the cost of CCS can be reduced and the energy efficiency of the system can be improved.Coupling the cooling,heating,powering and lighting by solar energy with chemical conversion in assisting CCS technology can explore the potential in solar energy efficient utilization.The key points of the carbon capture technology assisted by renewable energy,waste heat and combination of them focus on the process match,optimized cascade unitization of energy and the refining of comprehensive evaluation and index system.
