The Icelandic Deep Drilling Project (IDDP) is a consortium of three, Icelandic energy companies preparing to drill a 4-5 km deep drillhole into a high-temperature hydrothermal system. The goal is to reach 400-600°C (752-1112°F) supercritical hydrous fluid at a rifted plate margin on a mid-ocean ridge. The main purpose of the IDDP is to find out if it´s economically feasible to extract energy and chemicals out of hydrothermal systems at supercritical conditions.
Potential benefits of the IDDP include increased power output per well, perhaps by and order in magnitude, and production of higher-level, high-pressure, high-temperature steam. Also, the development of an environmentally-friendly energy source below currently producing energy fields. In addition, the extended lifetime of the exploited geothermal reservoirs. The IDDP consortium is composed of Hitaveita Suðurnesja (HS), Orkuveita Reykjavíkur (OR), Landsvirkjun (LV) and the National Energy Authority of Iceland (Orkustofnun).
