C0₂ Neutral energy system utilising the subsurface. WP4 Geo-model development, reservoir modelling and GIS

This report is part of the energy research project CO₂ Neutral energy system utilising the subsurface (CONvert). The overall project objective is to analyse the techno-economic feasibility of an integrated energy system, where the subsurface is utilised for thermal energy production and storage, as well as temporary CO₂ storage (Figure 1).
WP4 will identify subsurface geological structures and reservoir sandstones and will select the most attractive sites for storage of CH4 /CO₂ , hot water, CO₂ and geothermal production. Productivity and injectivity are vital for the usability of the subsurface and governs the configuration of the individual subsurface installations. Subsurface reservoir modelling allows for simulation of both energy extraction (geothermal energy production) and storage. Different scenarios can be examined, and potential synergy effects can be optimized in the operating phase, but also facilitates the costly and uncertain exploration and installation phase. The WP4 aims at facilitating strategic decision making regarding early and future use of the subsurface as an active. All relevant data will be transferred to a GIS geodatabase.
