Fingerprinting industrial CO2 and testing noble gas and clumped isotope tracers and the Carbon Management Canada Field Research Station Enquiry

该项目将产生与监测安全CO2储存和识别来自工程储存地点的计划外CO2迁移的全球问题相关的新知识。它包括在稳定、成团和惰性气体同位素地球化学测量技术方面的培训，并对联合王国工业过程中捕获的二氧化碳进行取样和分析。这些指纹技术被应用于追踪注入加拿大碳管理实地研究站的CO2，并利用这些技术来确定注入该站点的CO2的命运。该项目的初始阶段将以上述近期工作为基础，对从包括制氢、钢铁制造和水泥生产在内的工业流程中捕获的二氧化碳进行取样和惰性气体以及碳和氧稳定和聚集同位素分析。这些指纹将与发电厂捕获的二氧化碳的现有测量结果进行比较，以确定燃料源和工业过程的温度如何控制天然示踪剂指纹。这些分析的结果将用于评估这些自然指纹在确定不同工程储存库中注入的CO2的命运以及追踪CO2从储存地点的非计划迁移方面的有效性。该项目的第二部分将建立在爱丁堡大学和加拿大碳管理（CMC）研究人员之间的现有合作基础上，CMC在联邦政府投资490万美元后，在加拿大阿尔伯塔开发了实地研究站（FRS）设施。FRS旨在将CO2注入两个相对较浅的层位（300和500米深），从而能够大规模研究CO2从更深的CO2储存地点迁移时的行为。现场设计允许在不同深度的地下流体取样，我们将对注入现场的CO2进行惰性气体和聚集同位素分析，并将其与迁移的CO2样品中的测量结果进行比较。这些测量将用于确定注入的CO2在穿过地下迁移时的惰性气体和聚集指纹的保留情况，并确定注入的CO2的捕集机制和捕集效率程度。研究的最后阶段将把这种惰性气体和成团同位素数据与将在FRS使用的其他监测技术（例如稳定同位素测量）进行比较。这将与项目初始阶段在工业二氧化碳中测量的指纹相结合，并允许确定工业二氧化碳中的固有指纹在追踪二氧化碳注入工程储存地点时的迁移和命运方面的有效性。

This project will generate new knowledge relevant to the worldwide problem of monitoring secure CO2 storage and identifying unplanned CO2 migration from an engineered storage site. It includes training in stable, clumped and noble gas isotope geochemical measurement techniques and undertake sampling and analysis of captured COifrom industrial processes in the UK. These fingerprinting techniques are applied to tracing CO2 injected into the Carbon Management Canada Field Research Station and use these to identify the fate of the CO2 injected into the site. The initial phase of the project will build on the recent work outlined above and undertake sampling and noble gas and C and O stable and clumped isotope analysis of CO2 captured from industrial processes including hydrogen production, steel manufacturing and cement production. These fingerprints will be compared to existing measurements of captured CO2 from power plants to establish how the fuel source, and temperature of the industrial process controls the natural tracer fingerprint. The results of these analysis will then be used to assess how effective these natural fingerprints will be in determining the fate of the injected CO2 in different engineered storage reservoirs and in tracing unplanned migration of the CO2 out of the storage site. he second portion of the project will build on an existing collaboration between researchers at the University of Edinburgh, and Carbon Management Canada (CMC) who have developed the field research station (FRS) facility in Alberta, Canada, following a $4.9-million investment by the Federal Government. The FRS is designed to inject CO2 into two relatively shallow horizons (300 and 500 m depth), enabling a large scale study of how CO2 may behave if it migrates from a deeper CO2 storage site. The site design permits sampling of subsurface fluids at various depths, and we will perform noble gas and clumped isotope analysis on the CO2 injected into the site and compare it to measurements made in migrated CO2 samples. These measurements will be used to establish how well the noble gas and clumped fingerprint of the injected CO2 is retained as it migrates through the subsurface and identify trapping mechanisms and degree of trapping efficiency of the injected CO2. The final phase of the study will perform a comparison of this noble gas and clumped isotope data to other monitoring techniques which will be utilised at the FRS (e.g. stable isotope measurements). This will be combined with the fingerprints measured in industrial CO2 from the initial phase of the project and allow determination of how effective inherent fingerprints within industrial CO2 will be at tracing the migration and fate of that CO2 when it is injected into an engineered storage site.
