Reykjanes Power is working on the Iceland Deep Drilling Project at the Reykjanes Peninsula in Iceland. On the 25th of January 2017 at 4,659 meters depth it reached a milestone. Temperature at the bottom of the well has already measured at 427°C, with fluid pressure of 340 bars.
The Iceland Deep Drilling Project
The National Energy Authority of Iceland (Orkustofnun)(OS) and four of Iceland’s leading energy companies: Hitaveita Sudurnesja (HS), Landsvirkjun, Orkuveita Reykjavíkur and Mannvit Engineering established this project called “Deep Vision” (IDDP).
The aim is to improve the economics of geothermal energy production. The strategy is to look at the usefulness of supercritical hydrothermal fluids as an economic energy source. In conclusion this will make it possible to tap the temperatures of more than 400 °C (750 °F) by drilling to depths greater than 4.000 meters. The drilling is at a rifted plate margin on the mid-oceanic ridge. Producing steam from a well in a reservoir hotter than 450 °C (840 °F) — at a proposed rate of around 0.67 cubic metres per second (24 cu ft/s) should be sufficient to generate around 45 MW. As a result of that the project could be a major step towards developing high-temperature geothermal resources.
“Deep Vision” recognised at its inception that much research would be needed.
Funding has come from the members of the consortium. The International Continental Scientific Drilling Program and the US National Science Foundation have contributed funding as well.
Researchers from UC Davis, UC Riverside, Stanford University, and the University of Oregon have taken the opportunity to collaborate with IDDP. They have aimed their investigation to gain information about extracting energy from hot rocks on land.
