Trends in Research on Latent Heat Storage Using PCM, A Bibliometric Analysis

Abstract

Latent heat thermal energy storage (LHTES) is particularly noteworthy thermal energy storage (TES) technology due to its high energy storage density. LHTES involves the use of phase change materials (PCMs) to store thermal energy, which can subsequently be used for heating and cooling applications as well as power generation. This paper outlines the techniques and tools employed to analyze existing literature on TES and LHTES systems research. Bibliometric, a statistical approach to analyzing written publications in specific fields of research, is used to identify significant findings and determine the course of scientific output. A strategic analysis of knowledge development is crucial for detecting opportunities and advancements within the field. This research offers valuable insights into the publication trends within the fields of TES and LHTES over the last three decades. Additionally, the study conducts a thorough examination of the geometric configurations of LHTES systems and their potential impacts on ongoing and future research. By tracking publication rates over thirty years, this study provides a comprehensive overview of how research in TES and LHTES has evolved. Understanding these trends helps researchers and policymakers gauge the growth and relevance of these fields in the context of energy storage and thermal management.
