The geothermal potential in the Pannonian Basin in Central and Eastern Europe offers widespread energy production solutions for consumers. Both deep and shallow geothermal energy production have been strongly increasing in this century, and the ambitions for the next decade are even higher. The large majority of the territory of Hungary provides bright prospects for deep geothermal exploration. Furthermore, Hungary intends to switch from the use of natural gas to renewable energy, and geothermal is the most popular energy source in the country. In the previous decade, the volume of geothermal energy production almost doubled, and in this decade the government wishes to triple it. Therefore, the interest is more and more on new geothermal projects and technologies. However, the geological background is one of a high temperature basin and not volcanic, so the potential is limited and mainly focuses on heat production. When we discuss with energy consumer clients, we have to describe to them the geothermal opportunities. The GeoInnovator Team has prepared a large number of geothermal project concepts for its clients in recent years. The concept series includes widespread technical solutions for deep, shallow, complex and hybrid geothermal technologies. The first professional challenge is to prepare a geothermal energy profile for the consumers. In the previous century, one simple technical concept was forced on all geothermal projects. Nowadays, there are numerous technological opportunities to take into consideration. Only the integrated utilization of a realistic geothermal profile and a detailed consumer’s profile results in a technically and economically successful geothermal project! They provide essential input for the field management of the targeted reservoirs. The two profiles (geothermal and consumer’s) enable us to prepare an accurate list of facilities and precise cost as well as calculations on returns still in the concept phase of the project. The present paper collects the best project type practices and reviews the latest geothermal profile preparation methodology. Moreover, the GeoInnovator Team has also prepared a projection in order to calculate the details of the national plan to triple the geothermal energy production in ten years. It reviews the general national geothermal potential, the main geological structures, the possible project type models, their opportunities, as well as their aggregate capacities by 2030. This projection can serve as a geothermal database for the new renewable energy strategies of Hungary and the European Union.
