6 FAQs about [Underground thermal energy storage application case]

What is underground thermal energy storage?

Rajandrea Sethi, in Encyclopedia of Energy Storage, 2022 The expression Underground Thermal Energy Storage (UTES) identifies shallow geothermal systems where heat from external sources (solar thermal collectors, industrial processes, combined heat and power systems) is stored seasonally into the ground to be used during periods of higher demand.

What is underground thermal energy storage (Utes)?

Underground Thermal Energy Storage (UTES) technologies need to be further developed and need to become an integral component in the future energy system infrastructure to meet variations in both the availability and demand of energy.

What is underground heat storage?

Ibrahim Dincer, Marc A. Rosen, in Exergy Analysis of Heating, Refrigerating and Air Conditioning, 2015 Underground heat storage, or underground thermal energy storage (UTES), has storing temperature range from around 0 °C to up to 40-50 °C. This operating temperature range is suitable for heating and cooling applications in HVAC.

What is the European underground thermal energy storage Alliance?

We suggest to launch the European Underground Thermal Energy Storage Alliance as part of the mission to bring Europe to the forefront of HT-UTES technology development and valorise the market Surface installation of the HT-ATES in Middenmeer, the Netherlands with connection to the heat network. Source: ECW Energy

What is Aalborg thermal energy storage?

Source: Aalborg Thermal energy storage is already implemented in heating networks in the form of surface tanks storage and, although still highly limited, by UTES to support the use of surplus heat from industry and the implementation of renewable heat sources such as bio-Combined Heat and Power (CHP), geothermal, and solar energy.

What is the difference between ground source heat pump and underground thermal energy storage?

In ground source heat pump systems the heat exchange between energy geostructures and the surrounding ground should be maximised. In contrast in underground thermal energy storage systems the heat exchange between energy geostructures and the surrounding ground should be minimised to preserve heat storage.
