Project description
Investigating underground mechanical discontinuities for safe CO2 geological sequestration
Within the context of the EU's commitment to eliminate CO2 emissions by 2050, Europe must undertake a series of parallel mitigation actions. One of them is the CO2 sequestration in geological repositories. However, a prerequisite for such an ambitious initiative is a deep understanding of the reservoir characteristics. CO2 injection operations could prove hazardous due to naturally-occurring or artificial underground mechanical discontinuities (MDs). The EU-funded DISCO2 STORE project will investigate MDs to provide a better interpretation of their effects as well as tools that will ensure safety in CO2 geological sequestration operations.
Objective
The current scientific consensus indicates that it is vital to reach zero carbon dioxide (CO2) emissions by 2050 in order to avoid a large number of negative and unprecedented impacts on our planet due to global warming, such as extreme weather events, significant sea level rise, extinction of species and loss of biodiversity, among many others. It is therefore clear that a series of parallel mitigation actions must be undertaken, among which CO2 sequestration in geological repositories plays a major role. A worldwide application of this technology can take place only if a long-term storage of CO2 is assured, which, in turn, depends on a deep understanding of the reservoir characteristics. In this context, naturally-occurring or artificial underground mechanical discontinuities (MDs) are ubiquitous features which constitute the primary reasons for possible hazards associated with CO2 injection operations. DISCO2 STORE consortium thoughtfully examines MDs, in order to provide new knowledge and tools towards a riskless CO2 injection practice. This enterprise is tackled by building an interdisciplinary and international network, gathering 12 institutions from EU and TC. It congregates 36 experienced researchers, from academic and non-academic institutions, that share their variety of research expertise by means of international secondments and promote high-level training in a topic of high social impact. In addition, 20 PhD students participate in the project, gaining knowledge and acquiring competences on this environmental hot topic, in an international and stimulating framework. The outputs of this ambitious research proposal permit a deeper understanding of the effects of MDs and contribute towards making CO2 geological sequestration operations a safer and more reachable alternative for the mitigation of the effects of global warming.
