Analysis of the Suitability of the Use of Hydrocarbon Deposits for CO2 and Hydrogen Storage in the Northern Moravia Region

Abstract

Geological storage of CO₂ is the final link in the technological chain CCS (Carbon Capture and Storage), one of the possible technologies for reducing greenhouse gas emissions arising from the burning of fossil fuels. CCS is one of the key energy technologies of the Strategic Energy Technology Plan of the European Union (SET-plan). In the Czech Republic, activities in the field of CCS have focused on research and development projects, including the mapping of geological structures suitable for potential CO₂ storage and the transposition of relevant European legislation – see Act No. 85/2012 Coll., on the Storage of Carbon Dioxide into Natural Rock Structures. One of the options for geological storage of CO₂ is the use of mined or mined hydrocarbon deposits. However, these structures could also be operated as underground CO₂ reservoirs, enabling its reuse. Yet some of them could also be used for hydrogen storage if these locations are appropriately incorporated into the construction of a new hydrogen infrastructure. The report presents part of the research results related to hydrocarbon deposits in the North Moravia region.
