Croatian Geothermal Potential are Conservatively Underestimated

Geothermal energy has enormous potential in Croatia, and the energy potential of shallow layers of soil, underground and surface water should not be ignored either. These were the main highlights of this year's first Seminar on the Possibilities of Renewable Energy Sources Implementatio named Energy from the Depths.

For example, the Croatian Hydrocarbons Agency (AZU) has designated 75 exploration areas and is currently conducting exploratory measurements of geothermal potential for use in district heating systems in Sisak, Velika Gorica, Osijek, Vinkovci, Zaprešić and Vukovar, after which two exploratory wells will be drilled. At the same time, the examples of cities such as Bjelovar show that, when there is will and desire, it is not difficult to start even very ambitious projects, all with the aim of becoming energy self-sufficient. In addition, AZU has recently announced a tender for concessionaires for six exploration areas for the power production from geothermal energy, with the first plants expected in 4 - 5 years. At the same time, the first Croatian geothermal power plant is unnecessarily burdened by a dispute over ownership, which, for now, has no end in sight. Finally, there is increasing interest in the use of geothermal water for heating greenhouses in agriculture. This should not be surprising, because the probability of finding (geo)thermal waters in Croatia is as high as 75%.

On the other hand, there are more and more people who decide to use ground-water and water-water heat pumps for heating, cooling and preparation of domestic hot water in the home, business premises and hotels, as well as in industry. Numerous completed projects, as well as those yet to be completed, show that everything is moving in the right direction.
