[PDF] Effects of thermal energy discharge on shallow groundwater

It is demonstrated that aquifer thermal energy discharge can affect aquifer bacteria and fauna, while at the same time controlling only a minor part of the total seasonal and spatial variability and therefore posing no likely threat to ecosystem functioning and drinking water protection in uncontaminated, shallow aquifers. The use of groundwater as a carrier of thermal

6 FAQs about [Shallow groundwater energy storage]

Is a shallow geothermal system a seasonal energy storage system?

However, a shallow geothermal system is not designated for seasonal energy storage. The system uses the steady earth temperature closer to the surface for daily cooling and heating . Therefore, this system's collector area is relatively equivalent to the building's cooling or heating load.

Where is shallow geothermal energy stored?

Shallow geothermal energy is stored in the Earth's uppermost layers, up to a few hundred meters deep, and can be extracted using a geothermal heat exchanger or ground source heat pump (GSHP). The heat exchanger paced 1 to 2 m below the surface from the shallow geothermal energy.

Are underground thermal energy storage systems sustainable?

The study aims to explore the potential of Underground Thermal Energy Storage (UTES) systems, including Aquifer Thermal Energy Storage (ATES) and Borehole Thermal Energy Storage (BTES), as sustainable solutions for managing energy supply and demand.

What is shallow groundwater?

Shallow groundwater is defined here as groundwater within the near-surface critical zone where annual aquifer temperature is highly variable (within approximately 6 m from land surface), and this variability is transferred to streams through groundwater discharge zones causing annual temperature signal mixing with characteristic outcomes.

Can shallow groundwater storage buffer plant water stress?

We show that as warming shifts the balance between water supply and demand, shallow groundwater storage can buffer plant water stress; but only where shallow groundwater connections are present, and not indefinitely. As warming persists, storage can be depleted and connections lost.

What are the standards for shallow geothermal energy?

There are national, local and industry standards (DB37/T 4308-2021 2021) and specifications (DZ/T 225-2009 2009) about the investigation and evaluation of shallow geothermal energy that provide calculation and assessment methods based on general geological and hydrogeological conditions.
