“…Since the energy level of low-temperature waste heat is close to the temperature requirement of domestic heating and hot water supply, efforts have been made to the utilization of low-temperature waste heat [7]. Absorption heat pumps, which can be driven by lowtemperature waste heat, are widely adopted and have shown promising applications [8,9].…”

Mobilized thermal energy storage (M-TES) system can balance the spatial mismatch between the waste heat source and the end-user side. In this study, an experimental test rig has been built to study the dynamic discharging characteristics and the storage performance of a three-phase absorption thermal energy storage (ATES) system. The test rig consists of an electric chiller, electric heaters, a control cabinet, plate heat exchangers and detachable storage tanks for mobilized applications. LiCl solution is chosen as a working fluid for its high energy storage density (ESD). The performances of the proposed storage system under three application scenarios, namely cooling, heating and combined cooling and heating were investigated. The experimental results show that the proposed storage system can achieve the ESD for 484~598 (kJ/kg solution) under different working conditions. The test results verify the potential mobilized application of three-phase ATES in district heating and cooling systems.

“…In fact, the challenge is to adopt or select the suitable ESS while being eco-friendly, which imposes choosing storage systems such as mechanical energy storage [14] and hydrogen fuel cell [15]. The former is usually used in short-term applications when a fast response is required and has been frequently used in small grids district systems [16,17]. It is found mainly in three different forms: flywheel [18], pumped hydro [19], and compressed air [20].…”
