In 2018, new legal framework was adopted - Croatia's energy resources have been consolidated in one place, which is the basis for creating a positive investment climate in a country that rationally manages its resources. In this regard, special emphasis was placed on the great potential of geotherms and the exploitation of geothermal water for energy purposes. The licensing process (hydrocarbon or geothermal) is carried out by the Croatian Hydrocarbon Agency established by the Government of the Republic of Croatia.
Croatia has an above-average geothermal gradient - even 60% higher than the European average and has the basic prerequisite for the use of geothermal water for energy purposes. Temperature rises around 4,9°C with every 100 m of depth at average. According to current estimates of existing geothermal sources, the current potential is 500 MW from geothermal energy.
Some of these are sources of very high temperatures, usually above 120 ° C or 150 ° C, which can be used for the production of electricity in geothermal energy, and sources with lower temperatures of 60°C or 80 ° C and higher, are suitable as hot water sources suitable for exploitation in district heating systems or in agriculture.
Geothermal potential in Croatia has been proven in cca existing 40 wells.
The Croatian Hydrocarbon Agency continues to work on the promotion and development of new models for geothermal energy management. Exploring potential sources of hot water involves making extremely expensive deep wells. This is high- risk investment that may not always produce a positive result.
Unlike other countries, in Croatia the process is simpler and provides a certain type of security because potentials have already been identified in previous oil and gas explorations. All data can be found in our Data Room.
