Scientists in Iceland drilled straight into 900°C magma by accident — so energy-dense was the well that resulted, it could produce nearly ten times the power of a conventional geothermal well
In 2009 a drill crew in northeast Iceland went looking for very hot water and hit something that was still moving. They were working at Krafla, a volcanic caldera about ten kilometres wide in one of the most active corners of Iceland. The plan was straightforward on paper: drill down more than four kilometres to reach water so hot and so compressed that it stops behaving like a liquid or a gas, a state scientists call supercritical. They never g…
In 2009, Icelandic engineers accidentally drilled directly into a magma chamber at 900°C under the Krafla volcano. This error gave rise to the first geothermal well "improved by magma" in the world, producing overheated steam at 450°C capable of generating up to ten times more electricity than a conventional well before its closure.
