A Review on Energy Storage Technologies: Current Trends and Future Opportunities

Abstract

Despite the fact that numerous energy storage technologies have already been reviewed in the scientific literature, these innovations are right now at various stages of technological development, with only a few having been demonstrated for use on a large scale. The majority of research articles on energy storage give detailed descriptions of these technologies, but there is little data on how these technologies compared when used for energy storage. This paper provides a comprehensive review on energy storage concepts and also compares the different energy storage technologies in terms of research trends and future opportunities. Among the reviewed energy storage technologies, the thermochemical energy storage (TCES) method stands as an attractive and potential alternative to the conventional heat storage methods like sensible and latent thermal energy storage (STES and LTES) for several reasons that include: high energy storage density, minimal heat losses between the system and surroundings, and long term heat storage.
