Horizontal Systems (Very Shallow Geothermal Energy)

Horizontal Systems (Very Shallow Geothermal Energy)


Horizontal systems are basically geothermal heat collectors and all their special forms (heat basket, trench collector, capillary tube mats), which are installed at a depth of 1 – 5 m. In this depth range, the systems are mainly influenced by physical soil parameters, such as soil type and moisture, bulk density and climate (rain, temperature, solar radiation). The working group Shallow Geothermal Energy determines all project-relevant parameters through pedological field and laboratory investigations.
Since there are no absolutely valid determinations of the potential for these collector systems (such as a TRT for vertical systems), due to their very different shapes, among other things, very conservative rules of thumb must be used for their installation. For this reason, the working group Shallow Geothermal Energy is focusing on the precise determination of potential and adequate dimensioning of these systems. This enables a site-specific optimised and economic application of this technology even in narrowly defined urban areas.

    Abstract

    To reduce the total cost of low enthalpy geothermal systems by 20-30 % the project will improve actual drilling/installation technologies and designs of Ground Source Heat Exchangers (GSHE’s). This will be combined with an holistic approach for optimum selection, design and implementation of complete systems across different underground and climate conditions. The proposal will focus on one hand on the development of more efficient and safe shallow geothermal systems and the reduction of the installation costs. This will be realized by improving drastically an existing, innovative vertical borehole installation technology of coaxial steel GSHE and by developing a helix type GSHE with a new, innovative installation methodology. These GSHE’s will be installed to a depth of 40 – 50 meters ensuring improved safety and faster permitting.
