In recent years, analytical tools and approaches to model the costs and benefits of energy storage have proliferated in parallel with the rapid growth in the energy storage market. Some analytical tools focus on the technologies themselves, with methods for projecting future energy storage technology costs and different cost metrics used to compare storage system designs. Other
Renewable energy systems require energy storage, and TES is used for heating and cooling applications [53]. Unlike photovoltaic units, solar systems predominantly harness the Sun''s thermal energy and have distinct efficiencies. However, they rely on a radiation source for thermal support. TES systems primarily store sensible and latent heat.

Pit thermal energy storage systems for solar district heating. A large share of around 50% of the total energy demand in Europe is used for heating and cooling purposes (HRE 2019).As more than three-quarters of this demand is met by non-renewable energy sources, this sector is a large contributor to the production of greenhouse gas emissions (Eurostat 2022).
Thermal energy storage, commonly called heat and cold storage, allows heat or cold to be used later. Energy storage can be divided into many categories, but this article focuses on thermal energy storage because this is a key technology in energy systems for conserving energy and increasing energy efficiency.
