Seasonal thermal energy storage: A techno-economic literature review
1. Introduction. The built environment accounts for a large proportion of worldwide energy consumption, and consequently, CO 2 emissions. For instance, the building sector accounts for ~40% of the energy consumption and 36%–38% of CO 2 emissions in both Europe and America [1, 2].Space heating and domestic hot water

It is proven that district heating and cooling (DHC) systems provide efficient energy solutions at a large scale. For instance, the Tokyo DHC system in Japan has successfully cut CO 2 emissions by 50 % and has achieved 44 % less consumption of primary energies [8].The DHC systems evolved through 5 generations as illustrated in

CALMAC IceBank Energy Storage Model C
Ice Bank model C tanks are second generation thermal energy storage. They come in different sizes to accommodate differing space constraints and offer a significant benefit— tanks can be bolted to each other due to their modular, internalized main headers. That means less distribution piping is needed. The result is reduced installation costs
Gravel-Water Thermal Energy Storage
Gravel-water thermal storage is a less-expensive version of tank storage, which is generally buried in the ground. These kinds of storage are mostly insulated on the side and the top. The storage media are normally a gravel and water mixture, which could also be sand or soil mixture with water [65,66].
