Solar energy storage in summer and heating in winter
There are several types of STES technology, covering a range of applications from single small buildings to community district heating networks. Generally, efficiency increases and the specific construction cost decreases with size. UTES (underground thermal energy storage), in which the storage medium may be geological strata ranging from earth or sand to solid bedrock, or aquifers.UTES technologies include: The first is Thermochemical Storage (TCS), which could provide storage for weeks – or even months – with zero heat loss. It works by drawing heat from a thermal source such as a heat pump, electrical heating element or solar thermal collector to dehydrate an active material, thereby ‘charging’ the thermal store.

An overview of four methods. Winter heating is energy intensive, but it is possible to save up warmth over summer and release it over winter. Several seasonal heat storage systems are.
Seasonal storage of solar thermal energy through supercooled phase change materials (PCM) offers a promising solution for decarbonizing space and water heating in winter.
Seasonal thermal energy storage (STES) harvests and stores sustainable heat sources, such as solar thermal energy and waste heat, in summer and uses them in winter for heating purposes, facilitating the replacement of fossil fuel-based heat supply and coordinating the seasonal mismatch between heat supply and demand [7].
Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, [1] is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season.
