Abstract

Carbon capture, utilization and storage (CCUS) is considered a major part of the Portuguese strategy for reducing CO2 emissions. Some industrial sectors, the most prominent being the cement sector, require the implementation of CO2 storage to reach carbon neutrality by 2050. This paper presents and characterizes the areas with potential for CO2 storage in mainland Portugal. The lithostratigraphic and tectonic frameworks of the onshore and offshore basins are presented; a site screening process was conducted, based on basin- and regional-scale assessments, resulting in the definition of eight possible storage clusters, seven of which are offshore. The storage capacity was estimated for those clusters, with a central (P50) value of 7.09 Gt; however, the most interesting locations are in the Lusitanian Basin (West Iberian Margin), both onshore and offshore, as they present high capacity and are located favourably in relation to the industrial CO2 emitters. Considering only the potential sites of this basin, their storage capacities are greater than 3 Gt CO2, of which 260 Mt are onshore.

葡萄牙具有CO2储存潜力的地质构造的识别和表征

碳捕获、利用和储存（CCUS）被认为是葡萄牙减少二氧化碳排放战略的主要组成部分。一些工业部门，最突出的是水泥部门，要求实施二氧化碳储存，以在2050年前实现碳中和。本文介绍并描述了葡萄牙大陆有潜力储存二氧化碳的地区。介绍了陆上和近海盆地的岩石地层和构造框架；根据盆地和区域规模的评估，进行了场地筛选过程，确定了八个可能的储存集群，其中七个在近海。估计了这些集群的存储容量，中心值（P50）为7.09 Gt；然而，最有趣的地点是卢西塔尼亚盆地（西伊比利亚边缘），包括陆上和海上，因为它们具有高容量，并且相对于工业二氧化碳排放国来说位置有利。仅考虑该盆地的潜在地点，其储存能力大于3 Gt CO2，其中260 Mt在陆上。专题收藏：本文是二氧化碳储存地球科学收藏的一部分，可在：https://www.lyellcollection.org/cc/geoscience-for-co2-storage

期刊介绍： Petroleum Geoscience is the international journal of geoenergy and applied earth science, and is co-owned by the Geological Society of London and the European Association of Geoscientists and Engineers (EAGE). Petroleum Geoscience transcends disciplinary boundaries and publishes a balanced mix of articles covering exploration, exploitation, appraisal, development and enhancement of sub-surface hydrocarbon resources and carbon repositories. The integration of disciplines in an applied context, whether for fluid production, carbon storage or related geoenergy applications, is a particular strength of the journal. Articles on enhancing exploration efficiency, lowering technological and environmental risk, and improving hydrocarbon recovery communicate the latest developments in sub-surface geoscience to a wide readership. Petroleum Geoscience provides a multidisciplinary forum for those engaged in the science and technology of the rock-related sub-surface disciplines. The journal reaches some 8000 individual subscribers, and a further 1100 institutional subscriptions provide global access to readers including geologists, geophysicists, petroleum and reservoir engineers, petrophysicists and geochemists in both academia and industry. The journal aims to share knowledge of reservoir geoscience and to reflect the international nature of its development.
