Science & Technology: British Company to Lead Research in Developing Cost-Effective Drilling Technology for Geothermal Systems

Geo-Drill: Cost-Effective Drilling Technology For Geothermal (News Release)

Geothermal is currently the most underutilised of renewable resources, principally due to the high costs associated with deep geothermal drilling. These high drilling costs are related to the increased drilling distance and tripping times, harsher environments (temperature, pressure and geothermal fluid composition), reduced information (e.g. drilling blind) and lithology.

Following its long history of expertise and knowledge in coatings, material properties and performance, TWI has teamed up with experts in geothermal drilling technology including operators, specialists with experience in materials performance in harsh geothermal environments and development of graphene based materials and coatings, and simulation experts, to develop a novel and cost-effective drilling technology for geothermal systems.

Project Geo-Drill, funded by the European Commission H2020 programme under Research and Innovation (Grant agreement number 815319), aims to develop “holistic” drilling technologies that have the potential to drastically reduce the cost of drilling to large depths and at high temperatures. Geo-Drill will, thus, enhance the growth of geothermal energy as it will enable the exploitation of deep geothermal energy to generate electricity while significantly reducing the environmental impact during drill activity by reducing the capital expenditure (CAPEX). The project kicked-off on 3rd April with a consortium meeting hosted by TWI and will run for a period of 42 months.
