UDC 662.997:621.181.6 ANALYSIS OF GLOBAL SCIENTIFIC RESEARCH IN THE FIELD OF SOLAR THERMAL ENERGY STORAGE SYSTEMS
Abstract
This article presents an in-depth analysis of international scientific research in the field of solar thermal energy storage technologies, with a particular focus on thermal energy storage systems. The study is based on scientific publications published between 2014 and 2024. Various technological approaches — latent heat storage, sensible heat storage, and thermochemical heat storage systems — were examined during the analysis. The technical parameters, advantages, disadvantages, and economic efficiency of each method were compared. The results contribute to identifying innovative directions in the development of solar thermal energy storage systems.
This analytical study employed a systematic methodology for reviewing scientific publications. Articles were selected from reputable scientific databases such as “Scopus”, “ScienceDirect”, “SpringerLink”, and “Web of Science”. The analysis covered scientific publications published between 2014 and 2024. The selected keywords included “Latent heat storage”, “Sensible heat storage”, and “Thermochemical heat storage”. The number of articles for each year was recorded in a dedicated table and presented in graphical form. The analysis was limited to scientific publications whose titles and topics corresponded specifically to the research focus.
The bibliometric analysis conducted shows that from 2014 to 2024, the number of publications on thermal energy storage technologies steadily increased, with the highest research activity observed in the field of latent heat storage.
Springer emerged as the leading platform with the highest number of publications in this area, while MDPI contained relatively fewer articles.
In terms of countries, China, the United Kingdom, and the United States were the most active in international research collaboration, with the Chinese Academy of Sciences and Tsinghua University leading in the number of publications.
