Abstract: Mobilized thermal energy storage (M-TES) systems present a viable alternative to traditional heating systems to meet the heat demands of dispersed consumers. This report uses a case study in Lebanon to provide a techno-economic evaluation of the M-TES system. The compatibility of M-TES with current heating systems was assessed by investigating the design specifications of the heating system. The results show that underfloor heating systems and fan coil heating systems are compatible with M-TES. Several operating schedules for M-TES were also developed, considering various transit methods. The study calculated the payback period (PBP) and net present value (NPV) for each case while estimating the costs and revenues for M-TES. Additionally, this study computed the quantity of CO 2 emissions reduction for different M-TES configurations. The optimal operating strategy involves using two containers and three transportation cycles per day, achieving the highest NPV, a PBP of 3 years, and a yearly CO 2 emissions reduction of 44,787.9 kg.
