Calin SebarchieviciThermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that provide a way of valorizing solar heat and reducing the energy demand of buildings. The principles of several energy storage methods and calculation of storage capacities are described. Sensible heat storage technologies, including water tank, underground, and packed-bed storage methods, are briefly reviewed. Additionally, latent-heat storage systems associated with phase-change materials for use in solar heating/cooling of buildings, solar water heating, heat-pump systems, and concentrating solar power plants as well as thermo-chemical storage are discussed. Finally, cool thermal energy storage is also briefly reviewed and outstanding information on the performance and costs of TES systems are included.

About Me
Ioan Sarbu is a professor emeritus and doctoral supervisor of the Department of Civil and Building Services Engineering at the Polytechnic University of Timisoara (UPT), Romania. He earned his civil engineering diploma in 1975 and PhD in 1993. Joining UPT in 1978, he has dedicated nearly 50 years to teaching and research. He was designated a European Engineer by FEANI in 2001 and has supervised up to 20 PhD students, 50 MSc theses, and 200 graduate projects. In 2019, he was named Professor Emeritus and received the Romanian Academy’s “Henri Coandă” Award. In 2023, he won the “Best Paper Award” and in 2025 the "Research Excellence Award" from ScienceFather, India. His research spans refrigeration, heat pumps, solar energy, thermal comfort, energy efficiency, water and heat distribution, and numerical simulations and optimisations in building services. He is a member of ASHRAE, IAHR, and the Romanian Association of Building Services Engineers. He has authored 400+ papers, 41 books, 10 book chapters, 160+ indexed articles, and 60 conference papers. He holds 6 patents, 15 innovations, and 30 software programs. His H-index is 19 (Clarivate), 21 (Scopus), 25 (ResearchGate), and 29 (Google Scholar) as of December 2025. With over 17,000 citations (2,800+ in Clarivate), his global recognition includes listings in Who’s Who, biographical dictionaries, and numerous awards. He ranks in the top 0.5% of researchers worldwide per the 2025 ScholarGPS rankings.
