项目摘要

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.

该项目将产生与监视安全二氧化碳存储并识别从工程存储站点的计划外CO2迁移的全球问题有关的新知识。它包括对稳定，结块和高贵的气体同位素地球化学测量技术进行培训，并对英国被捕获的Coifrom工业过程进行采样和分析。这些指纹技术应用于追踪加拿大碳管理局现场研究站的二氧化碳，并使用这些技术来识别注射到该站点的二氧化碳的命运。该项目的初始阶段将建立在上面概述的最新作品的基础上，并进行采样以及贵重气体以及稳定的稳定的以及块状的同位素分析，对工业过程中捕获的二氧化碳分析，包括氢生产，钢制造和水泥生产。这些指纹将与来自发电厂捕获的二氧化碳的现有测量值进行比较，以确定燃料来源和工业过程温度如何控制天然示踪剂指纹。然后，这些分析的结果将用于评估这些天然指纹在确定不同工程储存储层中注入的二氧化碳的命运以及追踪二氧化碳在存储位置中的计划外迁移的效果。该项目的第二部分将建立在爱丁堡大学研究人员与加拿大碳管理公司（CMC）之间的现有合作的基础上，这些加拿大碳管理层（CMC）在联邦政府进行了490万美元的投资后，在加拿大艾伯塔省开发了现场研究站（FRS）设施。 FRS设计为将二氧化碳注入两个相对较浅的视野（300 m和500 m的深度），从而大规模研究CO2是否从更深的二氧化碳存储位点迁移。该站点设计允许在各个深度对地下流体进行采样，我们将对注入现场的二氧化碳进行崇高的气体和集结的同位素分析，并将其与迁移的二氧化碳样品进行比较。这些测量结果将用于确定注射二氧化碳的贵重气体和集结指纹在迁移到地下并识别注射CO2的捕获机制以及捕获效率的程度时，将保留了多样。该研究的最后阶段将对这种贵重气体和团结的同位素数据进行比较与将在FRS上使用的其他监测技术（例如稳定的同位素测量）。这将与从项目的初始阶段开始在工业二氧化碳中测得的指纹结合使用，并允许确定工业二氧化碳内部的固有指纹在追踪该二氧化碳的迁移和命运时将其注入工程存储地点时的迁移和命运。
