“…Two further studies on assessing the geothermal potential at regional scale were done by Ondreka et al (2007) [23] and Gemelli et al (2011) [14]. Ondreka et al (2007) produced geothermal potential maps for two case study regions in south-western Germany, which took the thermal properties of the subsurface into account (based on the geology and hydrogeology).…”

GIS-based modelling of shallow geothermal energy potential for CO2 emission mitigation in urban areas

Keywords: GIS Urban planning Energy demand Geothermal energy iGuess Smart city energy a b s t r a c t Due to the rapidly increasing percentage of the population living in urban centres, there is a need to focus on the energy demand of these cities and the use of renewable energies instead of fossil fuels. In this paper, we develop a spatial model to determine the potential per parcel for using shallow geothermal energy, for space heating and hot water. The method is based on the space heating and hot water energy demand of each building and the specific heat extraction potential of the subsurface per parcel. With this information, along with the available space per parcel for boreholes, the percentage of the energy demand that could be supplied by geothermal energy is calculated. The potential reduction in CO 2 emissions should all possible geothermal energy be utilised, is also calculated. The method is applied to Ludwigsburg, Germany. It was found that CO 2 emissions could potentially be reduced by 29.7% if all space heating and hot water requirements were provided by geothermal energy, which would contribute to the sustainability of a city. The method is simple in execution and could be applied to other cities as the data used should be readily available. Another advantage is the implementation into the web based Smart City Energy platform which allows interactive exploration of solutions across the city.

GIS-supported mapping of low-temperature geothermal potential taking groundwater flow into account

et al. 2015

a b s t r a c tTo promote the utilization of ground-source heat pumps, a new methodology to calculate the lowtemperature geothermal potential (LTGP) of a region is presented. The methodology is applicable worldwide, and it considers both closed-and open-loop systems. This new approximation for closedloops calculates the admissible heat flux exchange with the ground according to an analytical solution of the heat transport equation in porous media. Open-loop systems are calculated as a function of a sustainable removable water flux and the temperature difference between groundwater and a referenced external body. The automated calculation in the setting of a GIS platform has allowed the performance of multilayered 3D mapping of the low-temperature geothermal potential for both types of exploitations considering all of the available information. An example of the application of the methodology in the Metropolitan Area of Barcelona (Spain) is also presented. Finally, a finite element analysis has been performed to quantify the accuracy of the method and the influence of heat advection processes in the LTGP.

Suitability Evaluation of Specific Shallow Geothermal Technologies Using a GIS-Based Multi Criteria Decision Analysis Implementing the Analytic Hierarchic Process

et al. 2018

Abstract:The exploitation potential of shallow geothermal energy is usually defined in terms of site-specific ground thermal characteristics. While true, this assumption limits the complexity of the analysis, since feasibility studies involve many other components that must be taken into account when calculating the effective market viability of a geothermal technology or the economic value of a shallow geothermal project. In addition, the results of a feasibility study are not simply the sum of the various factors since some components may be conflicting while others will be of a qualitative nature only. Different approaches are therefore needed to evaluate the suitability of an area for shallow geothermal installation. This paper introduces a new GIS platform-based multicriteria decision analysis method aimed at comparing as many different shallow geothermal relevant factors as possible. Using the Analytic Hierarchic Process Tool, a geolocalized Suitability Index was obtained for a specific technological case: the integrated technologies developed within the GEOTeCH Project. A suitability map for the technologies in question was drawn up for Europe.
