The Iceland Deep Drilling Project (IDDP) is a project a consortium of the National Energy Authority of Iceland (Orkustofnun) and three of Iceland's leading energy companies: Hitaveita Sudurnesja (HS), Landsvirkjun and Orkuveita Reykjavíkur. The consortium is referred to as 'Deep Vision'.[1][2]
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. This necessitates drilling to depths of greater than 4,000 metres (13,000 ft) in order to tap the temperatures of more than 400 °C (750 °F). The drilling is at a rifted plate margin on the mid-oceanic ridge.[2] 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. If this is correct, then the project could be a major step towards developing high-temperature geothermal resources.[3]
'Deep Vision' recognized at its inception that a lot of research would be needed into the poorly understood supercritical environment and as such sought to cincorporate the inclusion of the wider scientific community.[1]
Funding has come from the members of the consortium, the International Continental Scientific Drilling Program and the US National Science Foundation.[2]
