The influence of reinjection and hydrogeological parameters on thermal energy storage in brine aquifer

Dimensionless Thermal Efficiency Analysis for Aquifer Thermal Energy Storage

“…The performance of ATES systems under various hydrogeological properties and operating conditions remains an emerging subject of intensive research in the literature (Birdsell et al., 2021; Kranz & Frick, 2013; Liu et al., 2020; Vidal et al., 2022), and a more complete quantitative characterization of it constitutes a key step toward wider economic and scientific acceptance of this environmentally sustainable technology (Hoekstra et al., 2020). Heat losses from the stored plume arise from several dispersive processes.…”

“…Furthermore, ATES systems may also be combined or integrated synergistically with aquifer in-situ bioremediation systems (Ni et al, 2020;Wang et al, 2022), as changes in groundwater temperature can be exploited to alter biogeochemical processes and hasten or stimulate in-situ bioremediation processes (Bin Hudari et al, 2022;Keller et al, 2021;Regenspurg et al, 2020). The presence of three distinct temperature zones (background, cold well, warm well) in aquifers with ATES systems, together with advection caused by injection and extraction of water, may stimulate convective processes that facilitate the mixing required for in-situ chemical or biological remediation, and that move contaminants to regions where they can more easily be subjected to pump and treat (Zheng et al, 2022).The performance of ATES systems under various hydrogeological properties and operating conditions remains an emerging subject of intensive research in the literature (Birdsell et al, 2021;Kranz & Frick, 2013;Liu et al, 2020;Vidal et al, 2022), and a more complete quantitative characterization of it constitutes a key step toward wider economic and scientific acceptance of this environmentally sustainable technology (Hoekstra et al, 2020).
