Abstract
In territory of Hungary, located in central part of Carpathian basin big amount (more than 3000) of abandoned CH-wells were drilled in course of oil and natural gas exploration estimated part are suitable after recompletion for production of geothermal fluids of high surface temperature more than 100oC and high production rate (up to 4000 cu.m./day).
These wells are useful for power generation by ORC or single flash method and coupled generation of heat and electricity by gas engine, absorption method of cooling based in production of geothermal fluids content high amount of dissolved gas with gas/water ratio up to 10.
Information is provided on the status of the geothermal energy utilization ñ geothermal based power generation and direct use ñ in Hungary with emphasis on developments between 1998ñ2001.
The parameters of direct use were decreased in this period and the proportion of geothermal energy utilization in the energy balance of Hungary, despite the significance proven dynamic reserves (with reinjection) of 380 Mm3/a with heat content of 63,5 PJ/a at T = 40 oC is remained very low (0,25%).
Hungary has the reliance on imported natural gas in 70% and practically only in 1-2 places are exist in the country an integrated multi-purpose approach where drinking water supply, direct use with reinjection, bathing and other uses are implemented in integrated cascading system (e.g. City Hodmezovasarhely).
Three important factors for this low utilization: is a lack of support from the state in first, no consistent legal background and overtaxing.
