The applications of seasonal thermal energy storage (STES) facilitate the replacement of fossil fuel-based heat supply by alternative heat sources, such as solar thermal energy, geothermal energy, and waste heat generated from industries.
Direct seasonal thermal energy storage is more complicated because of the large number of PCMs storage units installed inside the tank and the high cost of heat insulation. Therefore, most of the current direct latent heat storage is based on short-term heat storage, and very few studies are aimed at long-term heat storage. Fig. 2.
Revelation of economic competitiveness of STES against existing heating options. Seasonal thermal energy storage (STES) holds great promise for storing summer heat for winter use. It allows renewable resources to meet the seasonal heat demand without resorting to fossil-based back up. This paper presents a techno-economic literature review of STES.
This paper reviews selected seasonal energy storage technologies, outlines potential use cases for electric utilities, identifies the technical challenges that could limit successful commercial deployment, describes developer initiatives to address those challenges, and includes estimated timelines to reach commercial deployment.
Common seasonal heat storage includes seasonal sensible heat storage, seasonal latent heat storage, and seasonal thermochemical heat storage. Among them, both sensible and latent heat are used to store solar energy directly in the material.
There is a wide variety of storage technologies competing to fulfil the requirements of a low carbon energy system. Thermal energy storage (TES) is the simplest and most well-established form of accommodating highly variable energy and demand in the transition to sustainable energy systems.
