Lazio
Geothermal Brine Project
-
ENEL has operated geothermal power plants in Italy since 1911
-
Lazio project area is in Cesano geothermal field, a well understood “Caldera” geological setting with underlying deep reservoir
-
Geologically de-risked due to ENEL’s extensive exploration drilling in the 1970s/1980s
-
Invested value: geophysics, 16x deep wells data and pilot plant trials
-
Geothermal fluid reservoir defined by drilling: 150-200°C at 1500m depth
-
Positive reservoir assessment in 2023 by STEAM (ex. ENEL project engineers) reported elevated levels of lithium, potassium & boron within the brines
-
Project area consists of 6 exploration licences covering 11,086 hectares containing historical wells
