The Iceland Deep Drilling Project (IDDP) is a geothermal project established in 2000 by a consortium of 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. The consortium is referred to as "Deep Vision".
The aim is to improve the economics of geothermal energy production. Its strategy is to look at the usefulness of supercritical hydrothermal fluids as an economic energy source. This necessitates drilling to depths of greater than in order to tap the temperatures of more than . The drilling is at a rifted plate margin on the mid-oceanic ridge. Producing steam from a well in a reservoir hotter than —at a proposed rate of around should be sufficient to generate around 45 MW. If this is correct, then the project could be a major step towards developing high-temperature geothermal resources.
