From scientific results to management policies

1. From scientific results to management policies Teodóra Szőcs Joerg Prestor, György Tóth, Annamária Nádor, Andrej Lapanje and the TRANSENERGY team Final Event of project TRANSENERGY – Transboundary geothermal energy resources of Slovenia, Austria, Hungary and Slovakia Vienna, 24th of June 2013

2. From scientific results … http://transenergy-eu.geologie.ac.at Geological 3D models Reservoir delineation Hydrogeochemistry Modelled depressions in the Pannonian aquifers Temperature map of basement

3. Consequences of regional flow systems TransEnergy Project Main aquifers/ geothermal reservoirs: Multilayered porous intergranular sediments; Lime stones, dolomites. SK A HU SLOV Pannonian Basin - hot sedimentary aquifer: utilization of geothermal energy ≈ thermal groundwater / fluid abstraction ICPDR, 2009 Governance of transboundary aquifers and resources is needed !

4. Energy policy (2009/28/EC) Integrated resource management of hydrogeothermal systems – two main policy aspects Water policy (2000/60/EC) Groundwater within aquifer and groundwater body Environmental objectives: Constant level / no intrusions protection of thermal water RBMPs : A, HU, SK, SI 2009 – 2015 – 2021 – Geothermal energy stored beneath the surface Energy objectives: Significant specific increments increased utilization of thermal water NREAPs: A, HU, SK, SI 2010 – 2020– 2030 Division of management of geothermal resources between two sectors is still seen as an obstacle to integration!

5. Energy policy (2009/28/EC) Strengths and weaknesses Water policy (2000/60/EC) Programmes of measures (RBMPs) Common Implementation Strategy Guidance Groundwater body delineation, Status assessment, Monitoring Just guidance!

6. EU Danube Region Strategy (EUSDR) 4 pillars, 11 priority areas Renewable energyGeothermal energy  Groundwater  Long term sustainable management is needed Water qualityGroundwater quality- Coordination through the ICPDR (WFD- DRBMP) Common basis for closer cooperation and governance at state levels Groundwater poorly, while geothermal energy better represented in EUSDR

7. Constraints for ranking in use of thermal water • WFD: • Priority of groundwater dependent ecosystems • Priority of drinking water utilization • Overall importance of public participation • Priority of existing utilizations • National specific priorities: • According to the existing acts and laws • Economic pressures (CH productions) • Environmental pressures • Pressures from environmentalist, public, etc. • Pressures of rising groundwater, „flood” protection • Pressures of local, regional interest (development plans, lobbies) • Neighbouring country’s specific priorities, • other than the home-country’s ones • drinking water and public health • medicinal purposes (balneology) • agriculture, livestock, and fish-farming • nature conservation • economic → energy use • other Vienna Basin

Ecosystems versus thermal water extractions Esztergom, Šturovo wells and springs Patince-spa, Csokonai-, Lilla springecosystems under rehabilitation SK Amsterdam centre Hun utca, egyedi panelház HU Tata spring group Pilis-hills Potential geothermal plant Gerecse-hills Hun utca, házsor Vértes-hills Main karstic recharge zones N Bakony-mountains

9. Long term sustainable management of geothermal resources Sustainability is reached when: • there is a favourable efficiency of resource exploitation, • the real expenses are not carried over to the next generation. What is local weakness (bad) and what is strength (good)? New potential tool for management: Benchmarking

10. Benchmarking10 main indicators to support long term sustainable transboundary thermal water management Balneological efficiency (10 m3/pers/day)

11. Very bad Bad Medium Benchmarking TTGWB „Mura – Zala“ in SI ? TTGWB „Mura – Zala“ in HU ? ?

12. Summary of Benchmarking in the TTGWB „Mura – Zala“ • Management efforts are not promoted adequately from user to user. • The 3 most significant issues to be promoted: • yearly reports of monitoring results - submitted by user and approved by granting authority, • critical level pointsof the abstracted wells - defined at least from other available data or locations, • public should get free accessible information, at least of quality status of waste water.

13. Conclusions • Joint cross borders models(geological, heat flow, groundwater flow and transport, hydro- and isotope geochemistry) enable us to understand the responses of natural systems to thermal water/energy extractions. • Geological Surveys are the organizations of choice. • Priorities have to be defined. • Benchmarking criteria should be applied and ranked in order to achieve a better evaluation of the use of the geothermal resource. It facilitates the management of priorities.
