water temperature difference of hydraulic energy storage

What is high-temperature aquifer thermal energy storage (HT-Ates)?

Provided by the Springer Nature SharedIt content-sharing initiative High-temperature aquifer thermal energy storage (HT-ATES) systems can help in balancing energy demand and supply for better use of infrastructures and resources. The aim of these systems is to store high amounts of heat to be reused later.

How do thermal and hydraulic loads affect aquifer displacement?

Both thermal and hydraulic loads have an important effect on the displacements within the aquifer. Uplift is concentrated near the central well at the surface. The presented dimensional and numerical analysis can be extended to other applications related to the injection and extraction of hot water into/out of the underground.

Can aquifer thermal energy storage be used in urban areas?

Application of Aquifer Thermal Energy Storage with High Temperatures (HT-ATES) ranging from 60–90 ◦C is a promising technique to store large amounts of energy in urban areas. However, these areas typically lack information on hydrogeological and thermal parameters of the subsurface to determine the potential for energy storage.

Is water a suitable heat storage material?

Consequently, water is a suitable heat storage material, and water is today used as a heat storage material in almost all heat stores for energy systems making use of a heat storage operating in the temperature interval from 0 °C to 100 °C. 2.2. Principles of sensible heat storage systems involving water

Does water have a high heat storage density?

From Table 2.1 it appears that water has a very high heat storage density both per weight and per volume compared to other potential heat storage materials. Furthermore, water is harmless, relatively inexpensive and easy to handle and store in the temperature interval from its freezing point 0 °C to its boiling point 100 °C.

Does hot water affect hydraulic performance?

The determined aquifer and well characteristics indicate its suitability for an ATES. The tested formation did not show any alteration of the hydraulic performance due to the injection of hot water. This fact was indicated by SWTs performed before and after the two PPTs.

In this study, a multi-physics model was developed to systematically investigate the thermal-hydraulic behavior of HT-ATES in naturally fractured reservoirs. The model was validated against experimental data, showing excellent agreement with production temperatures, with deviations within 3.2 %.
