Thermal energy storage (TES) applications are increasingly focusing on form-stable eutectic phase change materials (FSEPCMs). These materials blend two or more phase change materials (PCMs) to provide a stable, lower melting point, greater latent heat of formation, and ideal shape for TES functions, such as freezing, warming, and chilling. This bibliometric study offers a comprehensive overview of FSEPCM research, covering various types, characteristics, preparation techniques, and applications, along with key trends and challenges. Despite the significant advancements, there is a notable research gap in the long-term stability and scalability of FSEPCMs for industrial applications. The novelty of this study lies in its extensive bibliometric analysis, which highlights the evolution of research in this field over the past few decades. By critically analysing the literature, the study identifies significant research issues, leading authors, and a wide range of data sources, including scientific journals, conference proceedings, and patents. The critical outcome of this review underscores the need for innovative solutions to enhance the performance and durability of FSEPCMs, paving the way for their broader adoption in TES applications.
