Utilization of thermal water in the region and introduction to the web- based multi-lingual database Zalaegerszeg, M.Sc. Andrej Lapanje (GeoZS) Špela Kumelj (GeoZS) Zalaegerszeg, M.Sc. Andrej Lapanje (GeoZS) Špela Kumelj (GeoZS)

…on Slovenian side there are 13 users of thermal water at 11 localities on Hungarian part of project thermal water is used by 28 users at 20 localities… Direct use of geothermal energy is the only type of exploitation from geothermal reservoir sources in the T-JAM project area

Slides for presentation

PREPARATION OF QUESTIONNAIRE ON GEOTHERMAL DIRECT USE We use the standard internacional questionnaire form prepared by WGC (Lund et al.) We sent them together with short description to all direct heat users of geothermal energy in the T-JAM project area to fill in. The data we asked for are: -max. and avg. yield of the boreholes - inlet and outlet temperatures - purpose of use THE DATA ARE AS CREDIBLE AS THE RESULTS RECIEVED FROM USERS ARE CREDIBLE

Summary of geothermal utilization in the Mura-Zala basin Current overview shows the status as first half of 2010 Summary of geothermal utilization in the Mura-Zala basin Current overview shows the status as first half of 2010

Annual geothermal energy use in the regions and counties of both countries as of direct heat use category 1.Individual space heating (other than heat pumps) 2.Bathing and swimming 3.Space heating and air conditioning 4.District heating 5.Greenhouses Categories of use:

-Total flow rate at maximum utilization flow rate capacity of geothermal production wells in the Hungarian part is greater than that of the Slovenian part (greater area, longer history of utilisation) Hungarian part: 996 kg/s from 39 wells and spring in Hévíz which gives alone 400 kg/s. Slovenian part: 295 kg/s from the 25 wells. -Installed capacity of geothermal boreholes (maximum flow rate and the inlet and outlet temperature difference) Hungarian part:70,6 MWt, Slovenian part:38,83 MWt. DISCUSSION AND COMPARISON BETWEEN THE REGIONS OF BOTH COUNTRIES

-Average flow rate at annual utilization Hungarian part: 503,44 kg/s in total (or 50,5% of the total flow rate at maximum utilization), including 400 kg/s from the Hévíz spring Slovenian part: 124 kg/s (or 42% of the total flow rate at maximum utilization). -Geothermal energy used at annual utilization Hungarian part: 648 TJ/yr that correspond approximately to toe Slovenian part: 382 TJ/yr that correspond approximately to toe DISCUSSION AND COMPARISON BETWEEN THE REGIONS OF BOTH COUNTRIES

- Maximum available temperatures at wellheads In the Slovenian part the maximum available temperatures at wellheads are at Benedikt (78 °C at the Be-2/04 well), at Moravske Toplice Terme 3000 (72°C from the Mt-1, Mt-4 and Mt-5 wells), at Banovci Terme (68°C at the Ve-2 well) and at Lendava downtown (66°C from the well Le-2g). the Hungarian part, however, wellhead temperatures are even higher; the highest are at Zalakaros (106°C from the K-8 well, 96°C from the K-5 well), at Zalaegerszeg (98°C from the K-286 well) and at Lenti (70°C from the B-33 well DISCUSSION AND COMPARISON BETWEEN THE REGIONS OF BOTH COUNTRIES

Overview of geothermal energy direct use as of first half of necessity for systematic data collection and for improvement of the users' database with better data quality. - Recomendation for managment authorities (Energy bilance and monitoring). Number of geothermal direct heat use as well as the number of geothermal (ground source) heat pumps increases in both countries. CONCLUSIONS
