Deep geothermal energy Status • Electricity is produced in 24 countries, amounting to a total of 73.5 TWh/yr based on an installed capacity of 12.6 GWe1 • Direct heating from DGE resources generated more than 0.263 EJ/yr in 2015 • The vast majority of production is from hydrothermal resources. Potential2 • IEA: by 2050, electricity generation could reach 1400 TWh/yr, which is almost a 20-fold increase from 2015 and avoids 800 Mt/yr of CO2 emissions. Direct heating could reach 5.8 EJ/yr (1600 TWh) • Achieving these targets requires significant research, development and demonstration of innovative technologies 1Bertani,

Geothermal energy – National opportunities Geothermal heat pump systems • Heating and cooling for buildings, roads and industrial processes • Interaction with other energy sources • National environment-friendly energy use

Deep geothermal energy • Power production and heat production for direct use • Synergies with the petroleum sector • Market opportunities for national industry


GeoS’ mission

Develop sustainable and commercially competitive solutions for geothermal energy technologies and their integration in the energy system nationally and worldwide


GeoS aims to • be an international hub for expertise in geothermal energy technologies • perform high-impact research that addresses critical challenges related to improved performance and increased application of geothermal energy technologies • enhance innovation and value creation within geothermal technologies for the user partners and promote environment-friendly industries and societies • transfer industrial and academic R&D excellence, knowledge and technology from petroleum to geothermal energy applications • offer an attractive researcher training programme leading to enhanced career opportunities • accelerate research activity throughout the centre period by developing additional national and international joint research projects among the centre partners and associates


GeoS’ approach - 1 Main research tasks form pivot points for organization of activities • Improved design and operation of GHP systems • Reduced cost of drilling and well construction — sustained well integrity and flow assurance • Improved reservoir characterization for evaluation of geothermal sites • Evaluation of potential under uncertainty — reduction of project-specific risks


GeoS’ approach - 2 Research organization based on strong interaction, intersectoral and interdisciplinary collaboration

WP 1 Design and operation of geothermal heat pump systems Improved design and operation of GHP systems WP leader Senior Scientist Jan Kocbach, CMR Main objective Increased efficiency and reduced cost in design and operation of GHP systems adapted to local conditions Motivation • Large national potential for including GHP systems in flexible energy systems due to their adaptability with respect to extraction and storage of energy • Need for tools and guidelines for both design and operational phase to know when and how to incorporate GHP systems, and to adapt to local conditions Research targets • Optimized energy extraction and storage for large- and medium-sized borehole fields in interaction with complex thermal load profiles • Active utilization of the convective energy contribution from groundwater flow when appropriate • Reliable and cost-effective GHP-based solutions for de-icing roads and bridges


WP 2 Geothermal well construction and flow assurance

Reduced cost of drilling and well construction — sustained well integrity and flow assurance WP leader Senior Research Scientist Erlend Randeberg, IRIS Main objective Reduced well construction cost and improved monitoring solutions for DGE systems, including long-lasting well integrity and flow assurance with respect to scale and corrosion management. Motivation •

Drilling and well construction are based on conventional technologies and represent 30-50% of the total development costs for a conventional hydrothermal plant

Improved solutions for drilling, completion and instrumentation of geothermal wells need to be developed for feasible large-scale extraction of geothermal energy

Research targets • Innovative and cost-effective drilling and well technology for hard, hot and fractured rock, with sustainable well completion • Smart, novel and cost-effective technologies for prediction, monitoring and mitigation of scale and corrosion under the harsh conditions associated with geothermal systems


WP 3 Geological characterization for evaluating geothermal prospects Improved reservoir characterization of geothermal sites WP leader Senior Researcher Jan Tveranger, Uni Research Main objective Improve geothermal site planning, performance-forecasting and risk-evaluation by developing innovative techniques for reservoir characterization, visualization and monitoring. Motivation • The up-front loading of costs combined with project-specific development risks, such as suboptimal well placements and over-estimation of potential production, are still barriers to industry growth • The potential energy production from different rock types is poorly understood • Transfer of geo-characterization methods and -workflows from the petroleum industry has significant potential to enhance understanding of geothermal reservoirs Research targets • Optimized methods and workflows for integrated geological, geophysical, geo-mechanical and flowfield characterization and for co-visualization and analysis of datasets for geothermal sites • Cost-effective characterization balanced against reduction of project-specific geological risks


WP 4 Dynamic processes in stimulation and operation of geothermal reservoirs Evaluation of potential under uncertainty — reduction of project-specific risks WP leader Researcher Eirik Keilegavlen, UiB Main objective Derive new and improved technologies for geothermal reservoir stimulation and for maintaining long-term sustainable operations, including the development of planning tools for investment decisions Motivation • The practical implications of combined subsurface dynamics are far from understood, and methods for evaluation of potential energy production as well as for risk assessment and mitigation are needed. • From an investment perspective, it is important to understand how technological uncertainty related to engineering in complex environments combined with uncertain geology should be included in a larger decision-making Research targets • Improved sustainability, risk-assessment and risk-mitigation related to stimulation and operation of geothermal reservoirs • Appropriate tools for decision-making under uncertainty related to investment, development and operation of geothermal facilities
