The objective of the GEORISK project in the framework of Horizon 2020, is to facilitate the development of deep geothermal projects (geothermal heating or geothermal power) by developing suitable insurance schemes to mitigate the risks inherent to geothermal drilling. The first step of the project, presented here, is to set-up a risk register and propositions to assess those risks. Based on an extensive literature review, and on the knowledge from the expert of the project, the risk register aims at defining a comprehensive list of the risks associated with the development of deep geothermal projects given the current understanding and feedbacks. Considering the knowledge at the beginning of a geothermal project, the risk register also highlights the risks that would need mitigation through insurance schemes. The register contains 54 risks which are grouped in 6 categories. On top of listing the risks associated with geothermal drilling, the register will be useful for listing associated technical mitigation measures, considering that the insurance schemes will be needed only if the technical solutions are uneconomical. In the risk analysis step, each risk is then given a score via two usual risk indicators (degree of damage and likelihood of occurrence) and ranked. This step is performed by asking stakeholders to answer a questionnaire. Risk analysis is performed for different type of energy use, different countries and different geological settings. Main results for one group are presented and show that the main risks according to the respondents are mostly related to the uncertainties of the subsurface.
