“…One may wonder why this article does not quantify the geothermal potential from three aspects (Rman et al 2015a): potential of inactive wells, legislative and energy potentials as some of these data have tried to be gathered in the survey. Additionally, the sustainability of thermal water production from the regional Pannonian basin reservoirs is of major importance when planning further geothermal development (Buday et al 2015;Rman et al 2015b;Szanyi and Kovács 2010). The reason is that reliable geothermal source-specific data are extremely difficult to be provided to non-agencies.…”

Data on thermal water sources with outflow temperature of 30 °C and above were analyzed from the N-ern parts of Bosnia and Herzegovina, Serbia and Croatia, S-ern parts of Hungary, W-ern parts of Romania, and NE-ern parts of Slovenia, altogether from an area of 99,347 km 2. The overview identified 771 geothermal sources; only 7 were thermal springs. The average well depth is about 1.2 km. About 13% of wells are younger than 10 years, additional 17% below 30 years; while 26% are older than 50 years. Average thermal water outflow temperature is 54 °C being the highest, 170 °C, in Croatia. Most thermal water is produced from basin fill sediments-Lower and Upper Pannonian (Mio-Pliocene) loose sandstones which are tapped by 86% of wells. The rest appertains to basement rocks-fissured, fractured and karstified Paleozoic, Mesozoic and Middle Miocene metamorphic, carbonate and siliciclastic rocks. In total, 72% sources hold water rights, 6% mining rights, 2% geothermal rights and 1% has no rights. The permits allow much higher water abstraction as currently listed. Usage for bathing and balneology encompasses 24% of all active sources (155), some of these also with heating (23). 104 objects (16%) are used for heating, also district heating (13) and individual space heating (3). An additional 10% (70) are used in agriculture, mainly greenhouse heating. There are 41 reinjection wells (5%). It is primarily in Hungary that drinking water (17%), industrial usage (5%) and monitoring wells (2%) are also common.

“…Overproduction and failure to inject geothermal water may relate to lowering its level in the aquifer and production decline in the future (Szanyi and Kovács 2010;Axelsson 2010;Buday et al 2015). Another issue is also maximum utilisation of available resources, e.g., using cascaded systems.…”

Mogilno-Lodz Trough is located in central Poland. It is structural basin filled with Triassic-to-Quaternary sediments. Lower Jurassic formations in Poland have one of the best conditions for the heating purposes. Presently, on the area of the Trough, no geothermal plant operates, which utilises geothermal waters from Lower Jurassic formations. Sustainable use of geothermal waters covers, e.g., effective use of thermal energy from waters, before they are injected back to the deposit. Such sustainable use can be achieved in cascaded systems, utilising thermal energy of waters, which gradually lose temperature at following stages of cascaded systems. Geothermal waters and energy occurring in Lower Jurassic formations in Mogilno-Lodz Trough have been analysed in terms of chemical composition and temperature parameters. A dominant type of water is chloridesodium waters, with specific components contents, such as iodine, bromine, and iron. Lower Jurassic formations are deposited at different depths, which affects, to a high extent, water mineralization and temperature, as well as some elements contents. It has been demonstrated which parameters are decisive about a possibility of using them at particular stages of a cascaded system and where one should expect to find suitable conditions for particular applications.

“…Hungary's excellent geothermal potential, its different hydrogeothermal systems and its thermal water utilization options have been described in numerous studies over the past years (Szűcs and Madarász 2013). The country's heterogeneous geological and hydrogeological situation indicate that the scope of current geothermal methods (Buday et al 2015) could be extended.…”

There are many compelling arguments for using geothermal energy in Hungary. One of the most important is that the country could thereby exploit its abundant, relatively untapped network of geothermal reservoirs. These are considerably warmer and closer to the surface than in most of Europe. In the foreseeable future, Hungary’s geothermal resources can satisfy the conditions required for efficient energy production. The tremendous amount of energy stored in our geothermal reservoirs could satisfy much of the country’s long-term energy demand.Every geothermal project is designed to fulfill its project objectives by meeting time, budget, technical, and legal/regulatory provisions. Geothermal development is necessarily exposed to risks of varying degrees throughout its development, something which distinguishes geothermal from other kinds of renewable-energy projects. These risks most often concern the availability, amount, suitability, sustainability and use-potential of the geothermal resource, but may also include market, financing, commercial and macro-economic risks.
