Evaluation of the Shallow Geothermal Potential for Heating and Cooling and Its Integration in the Socioeconomic Environment: A Case Study in the Region of Murcia, Spain

In order to boost the use of shallow geothermal energy, reliable and sound information concerning its potential must be provided public energy decision-makers, among others. To this end, we developed a GIS-based methodology that allowed us estimate resource, economic environmental at regional scale. Our method focuses on closed-loop borehole heat exchanger systems, which are by far systems most utilized for heating cooling purposes, whose demands similar throughout year in study area applied. The resource was assessed based thermal properties from surface depth 100 m, considering water saturation grade materials. Additionally, climate building characteristics data were also used as main input. G.POT assessing annual specific extraction (sHe) rate estimation both and, first time, cooling. applied Region Murcia (Spain) thematic maps created with outputting results. They offer insight toward can extracted (MWh/year) (W/m); technical potential, making distinction over zones region; cost possible ground source pump (GSHP) installation, associated payback period producing energy; finally, GHG emissions savings derived usage. model output rates, compared those VDI 4640, prove slightly higher than previous one.
