碳中和目标下碳捕集、利用和封存技术的计量检测需求及挑战

Metrological Requirements and Challenges in Carbon Capture,Utilization and Storage Technologies for Achieving Carbon Neutrality

在碳中和目标下,碳捕集、利用与封存(Carbon Capture,Utilization and Storage,CCUS)体系作为重要减排手段,未来将以更快的速度和更大的规模在中国部署,并有望被纳入碳交易市场。在此过程中,流量测量、成分测量、二氧化碳泄漏检测、过程控制和效率评估对项目技术成本、运营安全、过程监管和环境将产生重大影响。对各影响因素开展测量和监测将是CCUS监管的关键。计量检测技术可为准确评价CCUS全过程经济性、有效性、持续性、安全性以及碳减排效果,提供可靠的测量方法和可信的数据基础。通过调研国内外CCUS领域计量检测技术进展,分析CCUS各环节面临的计量检测挑战,总结出CCUS发展中的具体计量检测需求,为未来计量检测更好地支持CCUS发展提出了建议。

In the context of carbon neutrality objectives,the Carbon Capture,Utilization,and Storage(CCUS)system,a vital method for emissions reduction,is expected to be deployed more rapidly and extensively in China.It is anticipated to integrate into the carbon trading market.Key aspects such as flow measurement,composition analysis,CO2 leakage detection,process control,and efficiency evaluation play critical roles in influencing the technical costs,operational safety,regulatory compliance,and environmental impact of CCUS projects.Effective measurement and monitoring are essential for the regulatory framework of CCUS.Metrology and testing technologies are imperative for providing accurate assessments of the economic viability,effectiveness,sustainability,and safety of CCUS processes,along with their carbon emission reduction impact.This paper investigates the advancements in metrology and testing technologies in the CCUS sector,both domestically and internationally.It analyzes the metrological challenges encountered in various stages of CCUS,including process control,purity analysis,and leakage detection.We summarize the specific measurement and testing needs in CCUS development and propose recommendations to enhance metrological support for the future progression of CCUS.
