Research of Supercritical Water May Bring Geothermal Revolution (Geothermania)

In recent years, a large effort has been done to utilize a heat from the earth. Geothermal companies all over the world try to make another step to this goal. They get started an intensive research of supercritical fluids, mainly supercritical water (SCW).

SCW is a specific state of water which is very hot and under so much pressure that it exists somewhere between water and steam.  The boundary of this state are conditions with temperature higher than 374°C (705°F) and pressures over 22.1 MPa. SCW has several interesting features; its main disadvantage is the fact that it is very corrosive. On the other hand, advantages can be utilized in several industry segments.
