Database of shallow geothermal energy installations in Catalonia (BdIGSCat)

Collection of heat exchange systems with the subsoil by using installed geothermal heat pumps or in the project phase

Database of shallow geothermal energy installations in Catalonia (BdIGSCat) is a compilation of information about heat exchange systems that utilise subsoil energy via geothermal heat pumps which have been already installed or under construction.

DATA AUGUST 2021

The thermal power installed and / or in project accounted for in Catalonia for air conditioning and production of ACS reaches 42,38 MWt

Overview

The main purpose of this database is to provide updated and georeferenced information about the implementation state of shallow geothermal energy systems in Catalonia. Knowing how much energy is produced by shallow geothermal resources will allow to quantity and foresee how this renewable energy resource could contribute to the decarbonisation of our economic model. On the other hand, knowing the specific characteristics of each geothermal installation allow promoting the utilisation of geothermal energy as well as bringing potential users closer to this technology and its functionality.

Utilisation of shallow geothermal energy is increasing and it is being promoted both by public and private sectors. However, an official registration of this type of systems still does not exist in Catalonia; therefore, the BdIGSCat database is a starting point of visualisation of shallow geothermal energy installations in Catalonia.

Different equipment and drilling detail

Information in this database is continuously updated with the newest data collected both from public and private sectors. Each geothermal installation registered in the database collects data about the building typology (private or public), technical characteristics of heat exchangers, energy collection field, how generated energy is used and total energy production potential.

The database was developed by ICGC within GeoEnergia project (Geothermal resources of Catalonia) with the support from Catalan Institute of Energy (ICAEN) and Catalan Agency of Water (ACA) and in collaboration with the Cluster de l'Energia Eficient de Catalunya (CEEC) team.



Last update of data: August 2021

The information compiled from the data collected from the BdIGSCat is consultable through the Geoindex-Surface geothermal viewer, which includes two layers of information: the location and the main characteristics of the facilities promoted by the public sector and a Counting by municipality of the installations promoted by the private sector on the update date.

Shallow geothermal data

The information in the BdIGSCat database presents synthesized information of the installed (or in project phase) thermal power attained from geothermal heat pumps which are producing air for conditioning or sanitary hot water (SHW) in Catalonia at the date of data actualization.

According to inventory of August 2021, the BdIGSCat database consists of 739 records, corresponding to different types of shallow geothermal installations distributed throughout the territory of Catalonia. Table 1 shows the summary of the thermal power distribution by type of heat exchange system.



(*) This corresponds to the term "known thermal power" which refers to real and proven data of the installed geothermal pump.

(**) This corresponds to the term "estimated thermal power" which refers to the data inferred from the total length of the heat exchangers of the geothermal field when the data of the installed ground-source heat pumps is unkown.



Status charts

The following graphs show the most relevant data included in the BdIGSCat database of shallow geothermal energy installations in Catalonia in August 2021. Data can be filtered by provinces, regions and municipalities by activating and deactivating the corresponding cells within the data selectors. Charts are dynamically updated.

 


  • In Catalonia, 67% of shallow geothermal heat pump installations have an installed thermal power less than or equal to 30 kWt (Fig. 01). 13% correspond to installations between 30 and 70 kWt and only 5% of installations have installed thermal power between 70 and 100 kWt. 13% of the facilities have installed power between 100 and 500 kWt. Only 8 installations throughout Catalonia have installed thermal power over 500 kWt.
  • Even public sector has only 14% of total geothermal heat pump installations, the total thermal power installed in this sector is 22.6 MWt (Fig. 02). Whereas in the private sector with significantly much number of installations up to 75%, the total thermal power installed in this sector is 18 MWt.
  • Vertical closed loop geothermal systems are the type of heat exchange scheme predominant in Catalonia for air conditioning and sanitary hot water production (SHW) and corresponds to 84.3% of all geothermal installations (Fig. 03).
  • According to BDIGSCat database there is a progressive increase of shallow geothermal energy installations and consequently a progressive increase in the total MWt installed (Fig. 04): from 30.3 MWt in July 2019 to 42.38 MWt in August 2021.
