Finance: New Report on Geothermal Resource Risk Mitigation

Comparative Analysis of Approaches to Geothermal Resource Risk Mitigation (ESMAP)


Despite over 100 years of development and an estimated global potential of 70 to 80 GW, only about 15 percent of the known reserves are presently exploited and producing electricity.

The real or perceived uncertainty regarding the steam resource capacity during the early stages of geothermal field development makes it very difficult to mobilize the required risk capital, especially through the private sector, for the exploration drilling required to confirm the size, temperature, pressure, chemistry, and potential production rate of the resource.

Addressing this challenge is even more relevant given that the majority of sites suitable for development around the world are green fields (i.e., new fields), where the resource risks are often perceived to be especially high. A common theme that is apparent when reviewing global experience is that successful scale-up of geothermal development has benefited from some form of government facilitated support. While such support can come in many forms that can improve the overall profitability of geothermal projects, there are some schemes that specifically incentivize mobilization of risk capital into geothermal exploration drilling.
