Complementary toanalogue sites, other investigation programmes like nuclear waste storage, capture and geological storage of CO2 and oil and gasfield development will provide useful information and experiences.


WP_2.1 - Drilling and well completion technologies (BRGM, ETHZ, GFZ, ÍSOR, LIAG)

Sub-Programme 2 – SP2 (GFZ)Accessing and Engineering the reservoir

The activities proposed within this workpackage span from laboratory testing of spallation drilling to the development and testing ofsingle-well circulation systems. Such a system will be established at the Geozentrum Hannover/Germany to supply office andlaboratory buildings with geothermal heat, allowing an evaluation of the cost-efficiency of this concept of this technology. Other issuesin drilling are connected with the high temperatures found for supercritical reservoirs. Major efforts are made within the EERA jointprogramme on geothermal energy in the Icelandic Deep Drilling Project (IDDP) to both drill into condition of supercritical water andprogramme on geothermal energy in the Icelandic Deep Drilling Project (IDDP) to both drill into condition of supercritical water anddevelop high temperature measurement tools. Other important issues related to drilling such as underbalanced drilling for thedevelopment of EGS sites and the development of suitable completion technologies will be addressed within a not yet defined time, iffunding becomes available.

WP 2 2 Engineering a Reservoir (BRGM CNR CNRS CRES ETHZ GFZ ÍSOR LIAG TNO)WP_2.2 - Engineering a Reservoir (BRGM, CNR, CNRS, CRES, ETHZ, GFZ, ÍSOR, LIAG, TNO)Stimulation methods applied in previous projects and at existing wells (Basel, Soultz, Groß Schönebeck, Hannover …) will beevaluated. If funding becomes available, testing of the newly developed methods in new or existing wells will help to demonstrate andrefine methods. In addition, the possibility for using alternative to water heat carrier fluids will be evaluated. A particular focus in thedevelopment of stimulation methods will be on the understanding and mitigation of induced seismicity and efforts will be made tobetter understand the seismic and geomechanic processes to evaluate the natural seismic hazards in selected areas in Europe.Finally, guidelines for licensing procedures will be developed and proposed to overcome the potential deadlock in permitting causedby the fear of unwanted seismic events.

WP 2.3- Innovative technologies for well logging (BRGM, CNRS, GFZ, ÍSOR, LIAG)WP_2.3 Innovative technologies for well logging (BRGM, CNRS, GFZ, ÍSOR, LIAG)Well logging tools developed for oil and gas industry can be applied for geothermal reservoir characterization however the hightemperature conditions present in the geothermal wells limit or inhibit their range of operation. New high-temperature down-holesensing tools will be developed and a new analysis approach for monitoring of dynamic processes in deep geothermal systemsincluding supercritical fluid systems will be tested.


WP 3 1 Heat transfer process (BRGM GFZ ÍSOR KIT)

Sub-Programme 3 – SP3 (KIT)Process Engineering and Design of the Power System

WP_3.1 Heat transfer process (BRGM, GFZ, ÍSOR, KIT)Numerical tools, laboratory and on-site tests will be performed for the design of the more efficient heat extraction from the geothermalfluid. Also the working fluid and its coupling to the geothermal water lead to complex interactions within the heat exchanger. A keyaspect for the heat transfer is also material selection in order to realise an enduring and efficient heat transfer.

WP 3 2 P t (CNR CRES GFZ KIT)WP_3.2 Power systems (CNR, CRES, GFZ, KIT)New binary power conversion systems will be tested in the range of 50 KW, to be able to offer low maintenance, reliable small-scalesolutions for remote areas without access to a power distribution grid. Such a unit will be commissioned, tested in Groß Schönebeckand shipped to Indonesia for further on-site use. Larger power stations (approx. 1 MW) will be set up and tested at Groß Schönebeckand in Indonesia to provide sustainable base-load power and test different power plant layouts for optimized net-power output.y

WP_3.3 Storage and provision of heat and chill (BRGM, CNR, CNRS, CRES, GFZ, KIT, LNEG)Dependant on the geothermal fluids conditions, like mass flow and temperature, and urban surrounding, flexible systems might beconsidered for combined production of electricity and heat. Producing heat or chill for a district heating system has consequences forthe electrical power loop due to the seasonal fluctuations Geothermal reservoirs offer the opportunity to store thermal energy in thethe electrical power loop due to the seasonal fluctuations. Geothermal reservoirs offer the opportunity to store thermal energy in thesubsurface so that the geothermal power system will be designed considering not only provision but also storage of heat or chill.


WP 4.1 Improvement of sustainability of geothermal resources (BRGM, CEGL, CNR, CNRS, ETHZ, GFZ, ISOR, TNO)

Sub-Programme 4 – SP4 (ISOR)Operation and Management of Geothermal Systems

Thesemodels will be complemented by laboratory measurements on rock cores and analogue materials. In addition, surface and down-holemonitoring methods will be applied to observe and detect changes occurring during the exploitation stage. Such monitoring will beperformed at Groß Schönebeck Soultz and at some high temperature wells in Icelandperformed at Groß Schönebeck, Soultz and at some high temperature wells in Iceland.

WP_4.2. Chemical and biological processes in reservoirs and surface installations (BRGM, CEGL, CNR, ETHZ, GFZ, ÍSOR, LIAG)Scaling and precipitation of salts will be monitored in wells as well as by numerical and laboratory testing. Long-term fluid-rockinteraction experiments at simulated in-situ condition in the laboratory will provide insight into the processes and rates of change inthe permeability development of reservoir rocks.

WP_4.3 Prolonged lifetime of boreholes and system components (BRGM, GFZ, ÍSOR)Corrosion and scaling are major problems when geothermal water flows through pipes, pumps and heat exchangers. To reduce theseeffects, detailed knowledge of local concentrations of salt, scale and minerals at each point in the cycle will be improved as well as, g , p y pthe knowledge of chemical processes for material selection and for the prevention of corrosion. Materials and tools will be developedto withstand corrosive conditions in geothermal wells and tested at the Groß Schönebeck site within the joint programme.

Sub-Programme 5 – SP5 (CEGL)Sustainability, Environment and Regulatory Framework

The total LCA includes traditional LCA, which is an established decision support tool with risk analysis and life cycle costs (LCC). Theintegration of all these tools overcomes the limitations of tradition LCA by including social and economic factors necessary for thesustainable use of a geothermal resource. This approach will be refined for existing systems in operation and be applied for theplanning of new operations.

WP 5 2 Social multi criteria evaluation (CEGL CRES)WP_5.2 – Social multi-criteria evaluation (CEGL, CRES)The SMCE is a new approach for energy policy analysis using tools from different disciplines such as sociology, economics, statisticsetc. This approach will be applied for the evaluation of a potential geothermal project, where public opposition and environmentalconcerns need to be addressed and weighed against economic interests and the security of energy supply.

ÍWP_5.3 Risk assessment and mitigation (CEGL, ETHZ, GFZ, ÍSOR, TNO)The sustainable geothermal development depends on the ability to assess and mitigate the risks associated to the different phases ofthe single project. For the investors the most relevant risks are mainly related to the uncertainties in assessing the resource duringthe exploration phase and to predict the production performance during the project life but in some cases the environmentalsustainability and social acceptance represent potential hurdles. Induced seismicity is a specific risk associated to the EGS projecty p p p y p p jdevelopment. In this WP the risk assessment tools and mitigation actions will be developed.
