1 Key factors and capacity building for developing geothermal energy Rolf Bracke, Karolina Andersson 2), Isabella Nardini, Stefan Schimpf-Willenbrink GZB International Geothermal Centre, Bochum, Germany 2) IGA International Geothermal Association IEA, Hanoi 2017

2 Capacity development is the process through which individuals, organizations and societies obtain, strengthen and maintain the capabilities to set and achieve their own development objectives over time. Capacity is about growth: growth of the individual in knowledge, skills and experience 2

3 5 key factors for developing geothermal resources & competences and capacity to match them 3

4 #1 What are the regional demands for electrical power and heat that might be supplied from a geothermal resource? EU Energy Demand: Light Emission at Night Geothermal Heat Flux Density Projects Light Emission by Night in Europe ( oevel.de/europ a_nacht.jpeg ) (Hurter et al.)

5 #2 What is the extent of the resource? Exploration & Geology 1. Geological, geophysical and geochemical Exploration 2. Integrated Data Interpretation 3. Conceptual geological Models 4. Reservoir Characterisation I. Moeck in: Best Practices in Geothermal Exploration (Harvey et al.)

6 #3 What is the resources sustainable capacity? Reservoir Engineering 1. Geophysical and petrophysical investigation and characterisation 2. Geomechanics and geohydraulics 3. Seismic interpretation 4. Surface & borehole geophysics 5. Reservoir simulation 6. Well stimulation and reservoir enhancement 7. Reservoir maintenance

7 #4 What are the available subsurface technologies for energy extraction from this resource? Drilling Technologies 1. Conventional Drilling Technologies 2. Novel well designs and workover 3. Well services 4. Non-conventional drilling technologies

8 #5 What are the available surface technologies for energy extraction from this resource? Infrastructure & Applications 1. Flash-Type & ORC-/Binary Powerplant Applications 2. Heating and Cooling of complex Infrastructures 3. Agriculture and Greenhouses 4. Hybrid Uses (e.g. Seawater Desalination) 5. Social and environmental aspects (e.g. micro-seismicity, noise, waste disposal)

9 So, how do the required scientific, economic, legal and engineering competences in academia, technology and crafting generate an added value? Quelle: BGR

18 Geothermal Education Opportunities IEA - Geothermal Conference Hanoi 15

19 Undergraduate Studies: Only a limited number of specific University Degree Programs are available. Many of them offer geothermal specialisation block courses integrated in programs of Geosciences, Georesources and types of Engineering. Graduate and Post-Graduate Studies: MSc Degree and PhD in geothermal-specific education, but only a few European Universities hold chairs in Geothermal Energy and rarely in English (e.g. Bochum). International Geothermal Education Opportunities: Short courses/training/workshops offered through International Organizations (e.g. IGA Academy, EGEC). Mobility Programs: Not specific mobility programmes for geothermal researchers and students. Nevertheless researchers and students can make use of general mobility programmes such as Erasmus, Erasmus+, Marie Curie Actions and Cost Actions. Vocational Training: Vocational High Schools and Vocational Training Centres are widespread in Europe, but do not offer a satisfactory preparation for market demand in the geothermal sector.

26 Final considerations Increasing demand of geothermal experts due to the growing geothermal energy sector. Training in geothermal exploration, exploitation and utilization is available mostly in EU, US, JAP, NZ, Africa, LA but still inadequate for supply the high skilled workforce needed in the geothermal sector. High lack of specialists in many fields of expertise on different levels of skills for both shallow and deep geothermal. Lack of multidisciplinary expertise. New & more competences are required. Stronger focus on Asia! IEA - Geothermal Conference Hanoi 32
