ETIP-DG or European technology and Innovation Platform for Deep Geothermal is an open stakeholder group working towards the objective of enabling deep geothermal technology. The group recently hosted its Annual General Meeting that offered an opportunity for projects to highlight their work and impacts on the deep geothermal. Project Geo-Drill, working towards an impact objective of making geothermal drilling cost-effective, presented its contribution towards decreasing the costs of deep geothermal – providing a cost-effective holistic drilling technology. The project was presented by Volker Wittig, Head of Advanced Drilling Technologies at Fraunhofer Research Institution for Energy Infrastructures and Geothermal Systems IEG, as participant of the session on “R&I to decrease costs and improve efficiencies” during the meeting.
Despite the opportunities offered by Engineered Geothermal Systems (EGS) also known as Enhanced Geothermal Systems, exploitation of deep geothermal continues to be a challenge. The latter stems from deep EGS in hard rock where the cost escalates due to increased drilling distance, increase in tripping times, harsher inherent environments and reduced information of lithology. Project Geo-Drill promises a holistic drilling technology that can potentially reduce the cost of drilling via its novel Down-The-Hole (DTH) hammer with increased rate of penetration, sensors for real time monitoring, and innovative coatings and materials that offers increased component life.
