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.

缓解当前的气候危机取决于可再生能源、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氢燃料经济性的有效整合。后一种新兴技术基于并将扩展为捕获使用和存储（CCUS）开发的技术。挪威和英国在欧洲领导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，到2030年，四个英国能源集群将大规模部署CCUS）。CCUS越来越受到全球关注。国际行动计划（如巴西、印度尼西亚和马来西亚）现在旨在实施陆上和海上CCUS，以实现雄心勃勃的净零排放目标。这个及时和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伙伴关系联系起来，输出知识和经验，并开展研究，以应对有关地质CO2和H2储存的全球挑战。一个成功的CCUS项目需要在机械稳定的地层中进行有效的地下储存。这就需要对地下岩石进行详细的多尺度表征，以确定其CO2储存能力、注入和储存期间的机械行为变化以及监测泄漏和可能的流体迁移的能力。英国项目团队开发了新技术，从实验室到现场规模对CCUS活动进行定量分析和监测;然而，这些技术的应用主要集中在主要针对砂岩地层的特殊海上欧洲站点，对CO2几乎没有反应。国际合作伙伴的拟议目标（以及潜在的，但以前被忽视的英国目标）涉及对二氧化碳更具反应性的岩性，如碳酸盐岩，玄武岩，页岩和煤层。巴西的CCUS计划包括所有这些岩性作为潜在的储层目标，这些岩性在圣保罗的巴拉那沉积盆地都有很好的代表性，并且所需的经验和基础设施到位（石油和天然气巨头的承诺），以快速有效地实施CCUS。在这些反应性更强的地层中，注入CO2可能引发多种CO2-流体-岩石反应，包括矿物溶解和沉淀机制，这可能危及储层完整性，限制注入能力和传输效率。英国项目的组成部分先前已经展示了如何根据其独特的地球物理特征在实验室规模上检测类似的矿物学变化，并进行实时监测，从而实现早期预警。该项目（EHMPRES）旨在开发一种准确的方法，利用巴拉那沉积盆地的新岩石样本，检测与孔隙流体替代同时发生的CO2引起的矿物变化，以提供CO2反应CCUS站点的第一个详细特征。该方法包括对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，为使用地震和电磁方法进行远程地球物理监测提供信息。EHMPRES将在NOC和IEE/USP的CO2储存和储层表征方面的世界领先专家之间建立一个新的国际合作，这对于解释CCUS目标的反应性地质复合体至关重要。我们的研究结果将扩展到H2存储（全球需求不断增加）和CO2增强地热回收，这两种策略在概念上与CCUS相似。该项目将成为英国-圣保罗州长期合作网络的基础，以开发和验证评估全球范围内储存天然气的各种反应储层的工具，加强英国在CCUS研究中的领导地位。
