AAT Geothermae d.o.o. (AATG) was founded in 2012 and is developing CLEAG’s first power plant in Draškovec, Croatia. AATG is wholly owned by CLEAG and owns a license to develop and operate CLEAG power plants throughout Croatia.

Ideal place for the first power plant

Draškovec is in the Pannonian Basin, a geological formation that extends under Hungary and parts of Hungary’s neighbors. It is particularly suited to geothermal projects: (1) It reliably offers a water temperature of 100°C at a depth of only 1,900 m, (2) extensively researched in the past 30 years (5000 research wells). Exploration is not difficult and the cost of drilling to such a depth is not prohibitive. In addition, the water under the Draškovec site is rich in natural gas. One cubic meter of geothermal water on the surface contains ±2 kg of methane, which translates into a volume gas/water ratio of 3:1, with a high caloric value of gas at 9.5 kWh/m3 + hot water energy.

The project team built close relationships with important decision-makers in the national government, regional authorities and local municipality. Politicians and opinion leaders at all levels are very keen to be part of an initiative that could see Croatia pioneer a brand-new energy technology. We have involved nearby universities and technical colleges to give them an opportunity to learn about our technology and to share their experience with us. We hope to give the people exposed to CLEAG’s technology the sense that they have a stake in its success.

The site in Draškovec has been acquired and developed by AATG and all necessary permits to start the construction have been successfully obtained. Furthermore, we already pipelined additional projects and are constantly scouting for future sites.
