Our group started cooperating with IFP Energies nouvelles (French Institute of Petroleum: New Energy). The IFP’s young research group carries out researches on hydrogen degassing. The first meeting was held in September 2010 in the IFP’s main office in France, near Paris, where the parties presented their achievements in the field of studying hydrogen. The second meeting was held in October 2010 on the Russian Black Earth territory during the studies of hydrogen degassing structures – a circular depression with a diameter of 2.5 km.
