Building energy loads in cold climates may be largely offset with solar energy if seasonal thermal energy storage is employed. This article describes a full-scale experimental solar thermal system equipped with a 36 m 3 buried water tank for seasonal storage. The solar thermal system provides space heating and domestic hot water to an …
1. Introduction. Seasonal thermal energy storage (STES) systems are used to store excess solar energy in summer to supply domestic hot water and space heating in winter, effectively solving the problem of seasonal mismatch between solar energy supply and demand [1], [2], [3].The advantages of solar STES system mainly …
Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes. This paper is focused on TES technologies that …

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. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. …
STES works by collecting "sustainable heat", often produced by solar thermal panels, or "waste heat", which is generally recovered from an industrial process and which would be lost under …
Ground-coupled heat pumps (GCHP) integrated with inter-seasonal underground thermal energy storage systems are being investigated as an alternative way of heating and cooling buildings. This paper presents an experimental study of the coolth charging of an inter-seasonal underground thermal storage system using a 7.68 m2 unglazed solar collector.
Seasonal thermal energy storage (STES) is a promising key technology that can minimize the imbalance between the availability of solar energy and thermal energy demand. In this paper, a solar-assisted ground-coupled heat pump (SAGCHP) system that meets the DHW demand of 960 students was investigated by means of …

Thermal Energy Storage – Seasonal Thermal Energy Storage. Thermal Energy Storage is the key to doubling the Coefficient of Performance of Ground Source Heat Pumps. ICAX uses ThermalBanks to store heat energy from one season to another by exploiting the thermal inertia of the ground: heat only moves very slowly through the ground.
Electric thermal energy storage (e.g. Siemens Gamesa ETES) and power-to-molecules (e.g. Hydrogen) are the most promising seasonal storage technologies for the future. However, both options have a low level of technology maturity and have low cycle efficiency, causing notable energy losses.
Seasonal Heat Storage integrates the strengths of solar thermal collection in summer with seasonal thermal storage in ThermalBanks – in order to deliver heat through heat pumps more efficiently in winter. Low Carbon Economy. Nearly half the energy consumed in the UK is used in buildings – mostly for heating, cooling, lighting.
