Long-term energy storage concept

Research progress of seasonal thermal energy storage

The concept of seasonal thermal energy storage (STES), which uses the excess heat collected in summer to make up for the lack of heating in winter, is also known as long-term thermal storage [4]. Seasonal thermal energy storage was proposed in the United States in the 1960s, and research projects were carried out in the 1970s.

Thermal Energy Storage

Long/Short-Term Storage. As with all energy storage technologies, a key characteristic of TES systems is the span of time between charging and discharging. This means that the exergy losses of storage are lower than with sensible storage concepts because adding energy does not also increase the temperature-difference with the environment

Underground Gravity Energy Storage: A Solution for Long-Term

The concept of storing energy in abandoned mine shafts is described in . Storing energy in underground mines has 100 to 1000 times more energy storage capacity than Gravitricity because of the additional storage sites on the top and bottom of the mine. UGES should also be used if the focus is long-term energy storage, such as seasonal, 3 or

This 5S concept is one of the keys for energy efficiency and sustainable energy systems as well as better future. Heat storage for long-term purposes requires running the charging phase all summer long. In the storage phase, rock particles with high internal energy are stored in a bed. Heat losses are the main concern during the storage period.
