Seasonal thermal energy storage (STES) is a highly effective energy-use system that uses thermal storage media to store and utilize thermal energy over cycles, which is crucial for accomplishing low and zero carbon emissions.
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.
Within SolSpaces a new solar heating system, including adsorption storage for seasonal energy storage with binderless zeolite 13X as adsorbent, has been developed. The system concept is similar to the MonoSorp project with the difference that air solar collectors were used ( Fig. 13 ), therewith eliminating the need for a water to air heat
Thermal energy storage ( TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
Seasonal TES entails storing heat or cold when demand is low and then using it months later when demand is high. Possible storage systems include underground water tanks, underground aquifers, adiabatic compressed air and liquid air. Seasonal storage typically requires considerable planning and co-ordination between end-use demands and energy
The seasonal thermal storage technology is one of the most effective solutions for these problems, but the traditional seasonal thermal storage system encounters problems of large heat loss and low system efficiency.
This study focuses on the seasonal characteristics of heat and moisture migration in the soil, and the change frequency of boundary conditions is not high. So, four time steps (0.25 d, 0.5 d, 1 d and 2 d) are set for analysis. The temperature and moisture content in feature point 1, 3 and 5 can be shown in Fig. 10.

Seasonal thermal energy storage (TES) has been utilized to mitigate this mismatch by storing excessive solar energy in summer and releasing it for space and water heating in winter when needed 9
Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, 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.
By storing excess heat from solar panels or thermal power stations of more than 110 °C in summer, a medium deep borehole thermal energy storage (MD-BTES) can be operated on temperature levels
Seasonal storages make it possible to meet the seasonal heating or cooling demand with renewable energy sources produced months earlier. This can be especially valuable for meeting the expected increases in winter electricity demand amid the greater adoption of heat pumps in district heating networks, homes and other buildings.
Preliminary studies have shown that sugar alcohols (C4-C6 polyalcohols) may be used as the next generation seasonal heat storage materials [1], [2]. These materials have high latent heat of fusion, proper melting points (80–160 °C) for residential heating, and an evident supercooling effect for long-term low-loss liquid storage [3].

Seasonal storage: alternatives to the alternative. In an update to a report it published earlier this year, Norway-headquartered consultancy DNV GL outlined the role it sees for both seasonal heat
Humankind can effectively utilize only part of the solar energy reaching a surface of the Earth. It is due to the low density of the solar radiation and its unfavorable distribution. The majority of solar energy falls to the low latitude countries, where space-heating requirements are marginal. In these countries the solar heat is used for preparing water for washing or
The main goal of seasonal thermal energy storage (STES) is to store energy produced during summer as heat and reuse it during the winter months to heat buildings. The thermal energy is stored deep underground or just below the surface.
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.
Seasonal storage of solar thermal energy or of waste heat from heat and power cogeneration plants will significantly contribute to substitute fossil fuels in future energy systems. More than 30 international research and pilot seasonal thermal energy stores (TES) have been realized within the last 30 years. The dimensions of these pilot and

In the current era, national and international energy strategies are increasingly focused on promoting the adoption of clean and sustainable energy sources. In this perspective, thermal energy storage (TES) is essential in developing sustainable energy systems. Researchers examined thermochemical heat storage because of its benefits
Another popular alternative for seasonal heat storage is the thermochemical heat storage, which has multiple GJ/m 3 storage capacity and negligible heat loss [55], [13]. However sugar alcohols, in particular, xylitol, has a much lower melting point and can utilize liquid water as the working fluid.
ThermalBanks™ store heat between seasons. A Thermal Bank is a bank of earth used to store solar heat energy collected in the summer for use in winter to heat buildings.
The seasonal heat storage containing 140 C water will be used to store renewable energy obtained from solar, wind and other renewable sources. It also enables the storage of waste heat. Energy stored in the seasonal heat storage will replace the use of natural gas in the winter season and reduce carbon dioxide emissions from heat
Seasonal thermal energy storage (often referred to as STES) is a method of storing thermal energy for later use, typically over long time periods (which can go as far as months or even a full year).
MgCl2 hydrates are considered as high-potential candidates for seasonal heat storage materials. These materials have high storage capacity and fast dehydration kinetics. However, as a side reaction to dehydration, hydrolysis may occur. Hydrolysis is an irreversible reaction, which produces HCl gas thus affec
Seasonal Thermal Energy Storage (STES) takes this same concept of taking heat during times of surplus and storing it until demand increases but applied over a period of months as opposed to hours. Waste or excess heat generally produced in the summer when heating demand is low can be stored for periods of up to 6 months.
The possibility of converting the stored heat back to electricity is also investigated in the NewSETS project. The heat transfer to and from the storage medium is done via a patented pipe system, which is already successfully demonstrated in Polar Night Energy''s 3 MWh pilot plant in Hiedanranta, Tampere, Finland.
