6 FAQs about [Ground energy storage high energy off the ground]

What is underground thermal energy storage?

Underground thermal energy storage (UTES) is a form of STES useful for long-term purposes owing to its high storage capacity and low cost (IEA I. E. A., 2018). UTES effectively stores the thermal energy of hot and cold seasons, solar energy, or waste heat of industrial processes for a relatively long time and seasonally (Lee, 2012).

What is underground thermal energy storage (Utes)?

Alessandro Casasso, ... Rajandrea Sethi 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.

Why is the underground a good place to store thermal energy?

The underground is suitable for thermal energy storage because it has high thermal inertia, i.e. if undisturbed below 10-15 m depth, the ground temperature is weakly affected by local above ground climate variations and maintains a stable temperature [76, 77, 78].

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.

What are the limitations of underground thermal energy storage systems?

However, as reported by Lanahan and Tabares-Velasco (2017), limitations of underground thermal energy storage systems applied with elements such as energy piles include the comparatively large amount of heat loss compared to insulated water tank or gravel tank systems (Schmidt and Mangold, 2006; Rad and Fung, 2016).

Where is thermal energy stored?

There are three typical underground locations in which thermal energy is stored: boreholes, aquifers, and caverns or pits. The storage medium typically used for this method of thermal energy storage is water. Boreholes are man-made vertical heat exchangers that work to transfer heat between the energy carrier and the ground layers.
