The mitigation of the current climate crisis depends on the effective integration of renewables, hydrocarbons, long-term subsurface storage of greenhouse gases, such as CO2, and promising new hydrogen (H2) fuel economy. The latter emerging technology builds on, and will extend, techniques developed for Capture Usage and Storage (CCUS). Norway and UK lead the existing and planned large scale CCUS projects in Europe, repurposing previous oil and gas extraction sites and infrastructure (e.g., four UK Energy clusters will deploy CCUS at scale by 2030). CCUS is of growing global interest. International action plans (e.g. Brazil, Indonesia and Malaysia) now aim to implement onshore and offshore CCUS to achieve ambitious Net Zero emissions targets. This timely and innovative project aims to connect UK expertise in environmental science and CCUS to new partnerships in these countries, exporting knowledge and experience, and conducting research to address global challenges concerning geological CO2 and H2 storage. A successful CCUS project requires efficient subsurface storage in mechanically stable formations. This requires detailed, multi-scale characterization of subsurface rocks to determine their CO2 storage capacity, changes in their mechanical behaviour during injection and storage, and the capacity to monitor the onset of leakage and possible fluid migration. Novel technologies have been developed by the UK project team to quantitatively characterise and monitor CCUS activities from laboratory- to field-scale; however, application of these techniques has focused on the exceptional offshore European sites that largely target sandstone formations, barely reactive to CO2. Proposed targets of international partners (and potential, but previously disregarded UK targets) involve more reactive to CO2 lithologies, e.g. carbonates, basalts, shales and coal beds. Brazil's CCUS plan includes all these lithologies as potential reservoir targets, which are all well-represented in the Paraná Sedimentary Basin, Sao Paolo, and the required experience and infrastructure in place (the oil and gas majors' commitment) for rapid and effective CCUS implementation. The diverse CO2-fluid-rock reactions that CO2 injection can trigger in these more reactive formations include combined mineral dissolution and precipitation mechanisms, which can jeopardize reservoir integrity, limit injection capacity and transmission efficiency. The UK project components have previously shown how similar mineralogical changes can be detected at the laboratory scale based on their distinct geophysical character, and monitored in real-time, thus enabling early warning. This project (EHMPRES) seeks to develop an accurate methodology to detect CO2-induced mineral changes occurring simultaneously with pore fluid substitution, using new rock samples from Paraná Sedimentary Basin, to provide the first detailed characterisation of CO2-reactive CCUS sites. The methodology involves a combined laboratory assessment of the chemical, hydraulic and mechanical properties of CCUS candidate samples, to provide the necessary understanding of CO2-rock geochemical and geomechanical interactions, together with the associated geophysical signatures, for informing remote geophysical monitoring using seismic and electromagnetic methods. EHMPRES will establish a new international collaboration between world-leading experts in CO2 storage and reservoir characterization from NOC and IEE/USP, essential to enable interpretation of reactive geological complexes targeted for CCUS. Our findings will be extendable to H2 storage (with an increasing demand worldwide) and CO2-enhanced geothermal recovery, both conceptually similar strategies to CCUS. This project will form the basis of a long-term UK-São Paulo state collaborative network to develop and validate tools to assess a wide range of reactive reservoirs for storing gas worldwide, reinforcing the UK leadership in CCUS research.

当前气候危机的缓解取决于可再生能源、碳氢化合物、二氧化碳等温室气体的长期地下储存以及有前途的新型氢（H2）燃料经济性的有效整合。后者的新兴技术建立在为捕获使用和存储 (CCUS) 开发的技术之上，并将对其进行扩展。挪威和英国引领欧洲现有和计划中的大型 CCUS 项目，重新利用以前的石油和天然气开采场地和基础设施（例如，四个英国能源集群将在 2030 年大规模部署 CCUS）。 CCUS 引起了全球日益增长的兴趣。国际行动计划（例如巴西、印度尼西亚和马来西亚）目前的目标是实施陆上和海上 CCUS，以实现雄心勃勃的净零排放目标。这一及时且创新的项目旨在将英国在环境科学和 CCUS 方面的专业知识与这些国家的新合作伙伴联系起来，输出知识和经验，并开展研究以应对有关地质二氧化碳和氢气储存的全球挑战。成功的 CCUS 项目需要在机械稳定的地层中进行有效的地下储存。这需要对地下岩石进行详细的多尺度表征，以确定其二氧化碳储存能力、注入和储存过程中机械行为的变化，以及监测泄漏和可能的流体运移的能力。英国项目团队开发了新技术，用于定量描述和监测从实验室到现场规模的 CCUS 活动；然而，这些技术的应用主要集中在欧洲特殊的近海地点，这些地点主要针对砂岩地层，几乎不与二氧化碳发生反应。国际合作伙伴提出的目标（以及潜在的，但之前被忽视的英国目标）涉及对二氧化碳岩性更具反应性，例如碳酸盐、玄武岩、页岩和煤层。巴西的 CCUS 计划将所有这些岩性作为潜在的储层目标，这些岩性在圣保罗巴拉那沉积盆地都有很好的代表性，并且需要快速有效实施 CCUS 所需的经验和基础设施（石油和天然气巨头的承诺）。在这些更具反应性的地层中，二氧化碳注入可能引发多种二氧化碳-流体-岩石反应，包括矿物溶解和沉淀的联合机制，这可能会危及储层完整性，限制注入能力和传输效率。英国项目组成部分此前已展示了如何根据其独特的地球物理特征在实验室规模检测类似的矿物学变化，并进行实时监控，从而实现早期预警。该项目 (EHMPRES) 旨在开发一种准确的方法，使用来自巴拉那沉积盆地的新岩石样本来检测与孔隙流体替代同时发生的二氧化碳引起的矿物变化，以提供二氧化碳反应性 CCUS 地点的首次详细表征。该方法涉及对 CCUS 候选样品的化学、水力和机械特性进行综合实验室评估，以提供对 CO2-岩石地球化学和地质力学相互作用的必要了解，以及相关的地球物理特征，从而为使用地震和电磁方法的远程地球物理监测提供信息。 EHMPRES 将在来自 NOC 和 IEE/USP 的二氧化碳封存和储层表征领域的世界领先专家之间建立新的国际合作关系，这对于解释 CCUS 的反应性地质复合体至关重要。我们的研究结果将扩展到氢气储存（全球需求不断增加）和二氧化碳增强地热回收，这两种策略在概念上与 CCUS 相似。该项目将构成英国-圣保罗州长期合作网络的基础，以开发和验证工具来评估全球范围内用于储存天然气的各种反应储层，从而加强英国在 CCUS 研究方面的领导地位。
