Sentinel data for the detection of naturally occurring hydrogen emanations (sen4H2)



There is considerable interest in the use of Hydrogen as an alternative to hydrocarbon energy sources.

However naturally occurring sources of hydrogen are not common and historically there has been significant controversy as to mechanisms that may be related to the generation of hydrogen.

It appears that natural emanations of hydrogen have been detected in several places (e.g. Russia, USA, Brazil and Mali) with several ongoing activities to drill and recover it. As with water and oil, hydrogen comes out of the ground in various places.

Even if the origin of these emanations is not yet very well understood, possible geophysical and environmental changes associated with their formation and continuous emissions were observed. These empirical observations have associated elliptic terrain depressions and vegetation changes on areas where significant hydrogen leakages are detected.

Several studies are currently being conducted by the IFP Energies nouvelles (IFPEN) in partnership with ENGIE to better constrain hydrogen generation and migration in the subsurface.

This project will integrate EO derived information in support of these studies to determine the potential utility of EO based approaches for the detection of areas where hydrogen may be found. The team will integrate data from Sentinels 1, 2 and 3 with available in-situ data, prototype and potentially validate novel EO-based analysis linked with in-situ data to assess the feasibility of automatically detecting areas of possible hydrogen emissions and thus enabling the development of new EO-based services in this emerging market.
