The lead partner in Project Greensand, INEOS, has already applied for approval on behalf of licence partners Wintershall Dea (now Harbour Energy) and Nordsøfonden for Denmark''s first large-scale CO 2 storage facility, and is now working hard to start CO 2 storage in the North Sea by the end of 2025 or the beginning of 2026.
A numerical investigation of combined heat storage …
Heat storage capabilities of deep sedimentary geothermal reservoirs are evaluated through numerical model simulations. We combine storage with heat extraction in a doublet well system when storage phases are …
Storage Reservoir Operation and Management | SpringerLink
Schematic longitudinal cross-section of a drinking water reservoir serving also for flood protection and exhibiting thermal stratification. Several potential technical measures which increase management options are indicated: a pre-dam for sediment and nutrient control, supplemented by an underwater pre-dam serving the same purpose; various options for water …
Hydrogen storage capacity of salt caverns and deep aquifers …
The energy storage capacity (in TWh H2) of each of the structures analyzed and the number of analogous structures securing storage throughput demand in the aquifers are shown in Fig. 5 and Table 13. The variable results of the working capacity translate into the number of structures needed to secure the storage throughput in a given case.
Deep and shallow geothermal energy
Deep geothermal energy; Shallow geothermal energy; Long experience with deep geothermal energy (depth: 800–3000 metres) For many years, GEUS has conducted research and consultancy in connection with the assessment of the deep geothermal resources in Denmark. Often in close cooperation with private companies and public-sector institutions.
Pumped Storage Hydropower | Department of Energy
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
Denmark''s first CO2 storage facility is now ready to …
The thorough technical verification ensures that the stored CO2 remains safely and permanently in the closed Nini West reservoir 1,800 metres below the North Sea seabed, as expected. This is clear after the results of …

We develop a 3D model for a high-temperature aquifer thermal energy storage sys-tem using analysis of geological core data, sedimentological description, geophysi-cal data including well logs and ...
Optimal carbon storage reservoir management through deep reinforcement ...
All deep neural network models are implemented in PyTorch. Reservoir simulations are performed using the compositional reservoir simulator CMG–GEM, hereafter referred to as CMG for short [95]. Each simulation run uses a different permeability realization from the 400-realization ensemble, and the simulation results are saved for every 30 d.
