| Abstract | The DEEPEGS project is a demonstration project supported by the European Commission. The goal is to demonstrate the feasibility of enhanced geothermal systems (EGS) for delivering energy from renewable resources in Europe. It is a four-years project led by HS Orka Iceland and in cooperation with partners from Iceland, France, Germany, Italy and Norway. The project is testing stimulation technologies for EGS in deep wells in different geological settings, which will deliver new innovative solutions and models for wider deployments of EGS reservoirs with sufficient permeability for delivering significant amounts of geothermal power across Europe. The project demonstrates advanced technologies in three geothermal reservoir types that provide unique condition for demonstrating the applicability of this “tool bag” on different geological conditions. It will demonstrate EGS for widespread exploitation of high enthalpy heat (i) beneath existing hydrothermal field at Reykjanes (volcanic environment) with temperature up to 550°C and (ii) very deep hydrothermal reservoirs at Valence (crystalline and sandstone) and Vistrenque (limestone) with temperatures up to 220°C. The consortium is industry driven with five energy companies that will implement the project goal through cross-fertilisation and sharing of knowledge. The companies are all highly experienced in energy production, and three of them are already delivering power to national grids from geothermal resources. There is a special focus on business cases to demonstrate significant advances in bringing EGS derived energy (TRL6-7) routinely to market exploitation, with the potential to mobilise project outcomes to full market scales following the end of DEEPEGS project. The consortium seeks to understand social concerns about EGS deployments, and will address those concerns in a proactive manner, where the environment, health and safety issues are prioritised, and awareness raised for social acceptance. Furthermore, the consortium will carry out risk analysis and implement, as a part of the R&D approaches and as a core part of the business case development, hazard mitigation plan. |
