Supercritical Geothermal Resources Studied
The Csdworkshops.geo.arizona.edu site chronicles the search for supercritical geothermal resources. The U.S. has undeveloped potential for developing high-enthalpy geothermal systems in the western USA, Hawaii and Alaska.

Worldwide, the search is led by a program in the volcanic caldera of Krafla in NE Iceland; the Iceland Deep Drilling Project (IDDP) drilled to 2.1 km depth when 900°C rhyolite magma flowed into the well. In 2014 the IDDP plans to drill again, this time to to 4.5 km in the Reykjanes geothermal field in SW Iceland, to renew the search.

Similar plans are also are already underway in the Taupo Volcanic Zone of New Zealand (Project HADES) and at the Japan “Beyond Brittle Project” at about ~500°C, notes the author.
