“…Underground Thermal Energy Storage (TES) for cooling and heating of buildings has been employed in the United States [2][3][4][5], Europe [6][7][8][9][10][11], and other countries [12][13][14][15]. Recently, they have become more popular, considering the problems caused by the depletion of fossil fuels and the increase in global warming [16]. The ATES systems are generally considered as an economically viable tool for the seasonal storage of thermal energy [17].…”

“…They compared the di erent zonation patterns and determined the in uence of well-to-well distances. Jeon et al [16] conducted a sensitivity analysis of recovery e ciency in two cases of hightemperature ATES system with a single well to select the key parameters. For a fractional factorial design used to choose input parameters with uniformity, they considered the optimal Latin hypercube sampling with an enhanced stochastic evolutionary algorithm.…”

In this research, a con ned aquifer with low groundwater ow was considered to meet the cooling and heating requirements of residential complexes. The complexes were located in the cities of Ahvaz, Ardabil, Bandar Abbas, Esfahan, Kerman, Rasht, Tehran, and Zahedan. The complex in Ardabil mostly required heating, the ones in Ahvaz and Bandar Abbas mostly required cooling, and the complexes in other cities required both heating and cooling. Four di erent alternatives of Aquifer Thermal Energy Storage (ATES) were analyzed in this study. These alternatives consisted of using ATES: 1) alone for cooling, 2) coupled with a conventional refrigeration system or a chiller for cooling, 3) by employing at plate solar collectors for heating, and 4) by employing at plate solar collectors and a heat pump for heating. Thermal energy recovery factor and the annual Coe cient Of Performance (COP) of the alternatives were determined. The results showed that for buildings located in cities with mild climatic conditions (such as Esfahan), where the annual heating and cooling energy requirements were almost equal, the use of ATES would be highly recommendable, no matter through what alternative considered in this investigation.

“…For example, this could have a significant improvement for the recovery efficiency of HT-ATES wells that experience high heat losses during storage. Previous studies [31,52,53] evaluated the effect of several HT-ATES storage conditions on the recovery efficiency at V in = V out , and showed that energy losses can vary significantly. Therefore, it is recommended to analyse the combined effect of both varying storage conditions and the effect of volume (im)balance on recovery efficiency to get insight in the optimal combination of both factors for a given scenario.…”

Towards Sustainable Heat Supply with Decentralized Multi-Energy Systems by Integration of Subsurface Seasonal Heat Storage

In the energy transition, multi-energy systems are crucial to reduce the temporal, spatial and functional mismatch between sustainable energy supply and demand. Technologies as power-to-heat (PtH) allow flexible and effective utilisation of available surplus green electricity when integrated with seasonal heat storage options. However, insights and methods for integration of PtH and seasonal heat storage in multi-energy systems are lacking. Therefore, in this study, we developed methods for improved integration and control of a high temperature aquifer thermal energy storage (HT-ATES) system within a decentralized multi-energy system. To this end, we expanded and integrated a multi-energy system model with a numerical hydro-thermal model to dynamically simulate the functioning of several HT-ATES system designs for a case study of a neighbourhood of 2000 houses. Results show that the integration of HT-ATES with PtH allows 100% provision of the yearly heat demand, with a maximum 25% smaller heat pump than without HT-ATES. Success of the system is partly caused by the developed mode of operation whereby the heat pump lowers the threshold temperature of the HT-ATES, as this increases HT-ATES performance and decreases the overall costs of heat production. Overall, this study shows that the integration of HT-ATES in a multi-energy system is suitable to match annual heat demand and supply, and to increase local sustainable energy use.

Geochemical Changes Associated with High-Temperature Heat Storage at Intermediate Depth: Thermodynamic Equilibrium Models for the DeepStor Site in the Upper Rhine Graben, Germany

et al. 2021

The campus of the Karlsruhe Institute of Technology (KIT) contains several waste heat streams. In an effort to reduce greenhouse gas emissions by optimizing thermal power consumption on the campus, researchers at the KIT are proposing a ‘DeepStor’ project, which will sequester waste heat from these streams in an underground reservoir during the summer months, when the heat is not required. The stored heat will then be reproduced in the winter, when the campus’s thermal power demand is much higher. This paper contains a preliminary geochemical risk assessment for the operation of this subsurface, seasonal geothermal energy storage system. We used equilibrium thermodynamics to determine the potential phases and extent of mineral scale formation in the plant’s surface infrastructure, and to identify possible precipitation, dissolution, and ion exchange reactions that may lead to formation damage in the reservoir. The reservoir in question is the Meletta Beds of the Upper Rhein Graben’s Froidefontaine Formation. We modeled scale- and formation damage-causing reactions during six months of injecting 140 °C fluid into the reservoir during the summer thermal storage season and six months of injecting 80 °C fluid during the winter thermal consumption season. Overall, we ran the models for 5 years. Anhydrite and calcite are expected mineral scales during the thermal storage season (summer). Quartz is the predicted scale-forming mineral during the thermal consumption period (winter). Within ~20 m of the wellbores, magnesium and iron are leached from biotite; calcium and magnesium are leached from dolomite; and sodium, aluminum, and silica are leached from albite. These reactions lead to a net increase in both porosity and permeability in the wellbore adjacent region. At a distance of ~20–75 m from the wellbores, the leached ions recombine with the reservoir rocks to form a variety of clays, i.e., saponite, minnesotaite, and daphnite. These alteration products lead to a net loss in porosity and permeability in this zone. After each thermal storage and production cycle, the reservoir shows a net retention of heat, suggesting that the operation of the proposed DeepStor project could successfully store heat, if the geochemical risks described in this paper can managed.
