baseline in Italy
Studying migration of deep
seated gases, researchers of
Rome University have
performed geochemical
surveys over a wide range of
geological scenarios :
•
Volcanic areas
•
Tectonic areas
•
Adriatic through
•
As consequence CO2
baseline at regional and local
scale have been evaluated

•
Several areas suitable for CGS have been selected in
Italy (capacity about 12Gton)
•
No significant gas leakage has been found in the areas
suitable for CGS in Italy;
•
CO2 baseline at local and regional scales have been
acquired in central and south Italy (based on over
20.000 CO
2
measurements in soil air)
•
CO
2
continuous monitoring stations have been
installed in Italy both inland and offshore
•
Some industrial initiatives already exist in Italy
