“…As the temperature shifts for GWHPs remain within the limits of a ±6 K alteration recommended by the German norm VDI 4640 [69], no relevant change of microbial communities is thus expected. Mesophilic bacteria start appearing at 20 • C, and thermophilic bacteria appear at temperatures above 40 • C, which are typical of Aquifer Thermal Energy Storage (ATES) systems [27], where solar heat is injected during summer for its use during winter.…”

“…Another major concern is the possible (physio-)chemical alterations of groundwater due to temperature changes induced by the operation of GSHPs, in particular the temperature increases due to underground thermal energy storage [27]. Several studies were conducted in the Netherlands [28][29][30][31] and in Germany [32][33][34][35], where European trials of underground thermal energy storage are concentrated.…”

Ground source heat pumps (GSHPs) gained increasing interest owing to benefits such as low heating and cooling costs, reduction of greenhouse gas emissions, and no pollutant emissions on site. However, GSHPs may have various possible interactions with underground and groundwater, which, despite the extremely rare occurrence of relevant damages, has raised concerns on their sustainability. Possible criticalities for their installation are (hydro)geological features (artesian aquifers, swelling or soluble layers, landslide-prone areas), human activities (mines, quarries, landfills, contaminated sites), and groundwater quality. Thermal alterations due to the operation of GSHPs may have an impact on groundwater chemistry and on the efficiency of neighboring installations. So far, scientific studies excluded appraisable geochemical alterations within typical ranges of GSHPs (±6 K on the initial groundwater temperature); such alterations, however, may occur for aquifer thermal energy storage over 40 • C. Thermal interferences among neighboring installations may be severe in urban areas with a high plant density, thus highlighting the need for their proper management. These issues are presented here and framed from a groundwater quality protection perspective, providing the basis for a discussion on critical aspects to be tackled in the planning, authorization, installation, and operation phase. GSHPs turn out to be safe and sustainable if care is taken in such phases, and the best available techniques are adopted.

“…Along with warm or cold water, stored and recovered energy may originate from power-to-heat electricity [15], solar heat [16] or waste heat [17] sources. ATES systems are typically bi-directional systems, with a mono-well or a well doublet allowing for the injection and recovery of warm or cold water, able to run in heating and cooling mode [1,3,18]. The interested reader is referred to Hesaraki et al [2] and Xu et al [19] for detailed reviews of subsurface thermal energy storage.The interest aroused by thermal energy storage systems has increased in recent decades [20].…”

“…The interested reader is referred to Hesaraki et al [2] and Xu et al [19] for detailed reviews of subsurface thermal energy storage.The interest aroused by thermal energy storage systems has increased in recent decades [20]. The first ever thermal energy storage project was implemented in the 1960s in Shanghai, China [3,21]. Since then, ATES applications have extended worldwide, with more than 2800 running systems at the present time [3].…”

In the context of energy transition, new and renovated buildings often include heating and/or air conditioning energy-saving technologies based on sustainable energy sources, such as groundwater heat pumps with aquifer thermal energy storage. A new aquifer thermal energy storage system was designed and is under construction in the city of Liège, Belgium, along the Meuse River. This system will be the very first to operate in Wallonia (southern Belgium) and should serve as a reference for future shallow geothermal developments in the region. The targeted alluvial aquifer reservoir was thoroughly characterized using geophysics, pumping tests, and dye and heat tracer tests. A 3D groundwater flow heterogeneous numerical model coupled to heat transport was then developed, automatically calibrated with the state-of-the-art pilot points method, and used for simulating and assessing the future system efficiency. A transient simulation was run over a 25 year-period. The potential thermal impact on the aquifer, based on thermal needs from the future building, was simulated at its full capacity in continuous mode and quantified. While the results show some thermal feedback within the wells of the aquifer thermal energy storage system and heat loss to the aquifer, the thermal affected zone in the aquifer extends up to 980 m downstream of the building and the system efficiency seems suitable for long-term thermal energy production.

The integration of storage technologies into the hybrid energy system (HES) offers significant stability in delivering electricity to a remote community. In addition, the benefits of using storage devices for achieving high renewable energy (RE) contribution to the total energy supply are also paramount. The present study provides a detailed review on the utilization of pump‐hydro storage (PHS) related to the RE‐based stand‐alone and grid‐connected HESs. The PHS‐based HESs have been analyzed considering the technical details, including reliability, cost‐effectiveness, and environmental indicators. The optimization techniques are critically employed to the PHS‐based systems, including metaheuristics intelligent techniques, commercially available optimization and simulation tools, and recent advanced optimization tools. A comparative analysis of PHS integration to the stand‐alone and grid‐connected systems based on techno‐economic and environmental indicators over other storage technologies is also presented. The key technical and environmental challenges related to the PHS‐based HES are identified. Results from the recent research studies indicate that the PHS‐based HESs offer significant cost and environmental benefits over battery storage technologies. The study identifies that the particle swarm optimization is the mostly appreciated optimizing technique for cost‐effective energy supply and environmental aspects followed by hybrid optimization model for electric renewables and genetic algorithm.
