摘要
[目的]能源安全前提下的绿色低碳转型与工业结构调整是浙江省“碳达峰碳中和”工作面临的严峻挑战。由于浙江省煤电发电量占比较高,碳捕集利用与封存技术(CCUS)有望在浙江省能源与工业等领域的双碳技术体系中扮演重要角色,是实现化石能源大规模低碳利用的重要技术选择。[方法]从CO_(2)捕集、输送、利用与封存方面综述了浙江省CCUS技术的研究进展,介绍了浙江省CCUS工程示范项目的开展情况;总结了CCUS全链条各环节主要技术的特点,简要分析了当前CCUS技术发展的问题;展望了CCUS技术在浙江省的发展前景,并提出了发展建议。[结果]浙江省在CCUS各环节,特别是CO_(2)捕集方面拥有良好的技术储备。省内全流程示范项目工艺路线多样,捕集侧包括燃烧前和燃烧后捕集,利用与封存侧涵盖生物、矿化、化工利用及地质封存,各环节技术成熟度差异化较明显。项目规模较小,初投资和运行成本普遍较高,空间分布分散,不利于形成产业集群。[结论]需准确把握浙江省重点领域CCUS潜力和源汇条件,因地制宜推广CCUS集成项目,持续开展技术研发,并在激励机制、政策法规、商业模式等方面予以保障。
[Introduction]The green and low-carbon transformation and industrial restructuring under the premise of energy security is a serious challenge faced by Zhejiang Province to achieve its"carbon peaking and carbon neutrality"goals.Given the high proportion of coal-fired power generation in Zhejiang,carbon capture,utilization and storage(CCUS)technology,as an important choice to realize the low-carbon utilization of fossil energy,is vital to the"double carbon"technology system in the energy sector and industrial circle of the province.[Method]This paper presents a research review of CCUS technology from multiple aspects,including CO_(2) capture,transportation,utilization and storage,and introduces the development of CCUS demonstration projects in Zhejiang.This study summarizes the features of the major technologies throughout the full CCUS chain,and briefly analyzes the existing challenges amid the ongoing technological advancements.Besides,the prospect of CCUS technology in Zhejiang is explored along with corresponding suggestions.[Result]Zhejiang boasts a solid technical foundation in the field of CCUS,especially in CO_(2) capture,and has numerous fullchain demonstration projects employing various process routes,including pre-combustion and post-combustion capture(CO_(2) capture),biological,mineral,and chemical utilization(CO_(2) utilization),as well as geological storage(CO_(2) storage).However,technology readiness level differs largely across the process chain,in addition to other challenges,such as small scale,generally high initial capital and operating costs,and dispersed spatial distribution,which hinder the development of industrial clusters.[Conclusion]It is important to promote CCUS integration projects to adapt to local conditions,based on a thorough understanding of Zhejiang's potential and source/sink conditions related to CCUS in key areas.Additionally,continuous investment in technological research and development is necessary,along with guarantees in terms of incentive mechanisms,policies,regulations,and business models.
