DEEPEGS COORDINATOR DEEPEGS COORDINATOR DEEPEGS DEPLOYMENT OF DEEP ENHANCED GEOTHERMAL SYSTEMS FOR SUSTAINABLE ENERGY BUSINESS GEORG DRG -Open Conference 18-19 February 2016 Guðmundur Ómar Friðleifsson The DEEPEGS project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 690771

  2. DEEPEGS Project description DEEPEGS COORDINATOR DEPLOYMENT OF DEEP E NHANCED G EOTHERMAL S YSTEMS FOR SUSTAINABLE ENERGY BUSINESS • The DEEPEGS project is a demonstration project, supported by the European Commission, Horizon 2020. • The goal is to demonstrate the feasibility of enhanced geothermal systems (EGS) for delivering energy from renewable resources in Europe. • It is a 4 year project coordinated by HS Orka, Iceland, in cooperation with partners from Iceland, France, Germany, Italy, and Norway. Starting date was 1st December 2015. • The project will be testing stimulation technologies for EGS in deep wells in different geological settings, and intends to deliver new innovative solutions and models for wider deployments of EGS reservoirs with sufficient permeability to delivering significant amounts of geothermal power across Europe. • The project will demonstrate advanced technologies in three types of geothermal reservoirs, (i) in high enthalpy resource beneath existing hydrothermal field at Reykjanes with T up to 550°C and (ii) two very deep hydrothermal reservoirs in southern France with temperatures up to 220°C.

  5. DEEPEGS – objectives DEEPEGS COORDINATOR • To enhance understanding and accessibility of the deep geothermal potential • To improve and further develop methodologies and technologies • To apply the “ tool bag ” (methodologies and technologies), in partnership with industry to develop and/or enhance production at selected field locations. • To demonstrate the “ business case ” • To disseminate and communicate of the technology

DEEPEGS background experience DEEPEGS COORDINATOR Iceland Deep Drilling Project – IDDP Flow test 2010-2012 Superheated dry steam: 452°C, 140 bar, 3200 KJ/Kg – power output ~ 36 MW e Video clips at www.iddp.is Flow test continued 17. May 2011 – but needed to be stopped few days later. Continued 9.August 2011 but stopped 11. August for further modification. Opened again 27 th September 2011 for wet scrubbing and heat exchange test. From November 2011 to July 2012 flowing at 10-12 kg/sec

  16. DEEPEGS background experience DEEPEGS COORDINATOR Iceland Deep Drilling Project – IDDP Sequence of events: Apparently IDDP created a magmatic EGS system Thermally cracked the metamorphic contact aureole rocks by cold water drilling- and injection fluid Attracted 350 ° C two phase reservoir fluid from above – downwards - heating it up to 450 ° C Flowing the 450 ° C hot superheated steam - needing chemical mitigation for production By wet scrubbing Cl, S and SiO 2 were driven into the fluid phase – leaving pure steam for power production CO 2 proved to be lower than in atmosphere
