Over two intense days in March, 2017, TNO and UniRoma1 personnel collected samples of gas bubbling out of pools and creeks in four different areas of central Italy – Latera, San Vittorino, Ailano, and Fiumicino.

This gas is naturally produced deep underground by geological processes, and TNO will use a very new technique, called isotopologues, to try and determine the actual depth where this gas was originally formed.

For the monitoring of CCS sites, this method could help determine the origin of a CO2 anomaly near the surface and help determine if a leak has occurred or not.
