assessment of the prospects for oil and gas (ore, water, hydrogen) of large prospecting areas. The mobile direct search technology has been tested at hydrogen degassing sites in various regions of the world, including search areas in Europe. 

The results of instrumental measurements indicate that signals at hydrogen frequencies are almost always recorded within basaltic volcanoes. When scanning the section, hydrogen responses are recorded from the upper edges of basalt volcanoes to their roots. Consequently, basalt volcanoes are a kind of channels through which hydrogen migrates to the upper horizons of the section and further into the atmosphere. Within many basaltic volcanoes at depths of 68 km or 69 km, deep (living) water is synthesized. Hydrogen-enriched water is healing and can be used for health purposes. Hydrogen deposits can be formed by basalt volcanoes in adjacent seal-covered reservoirs It should be considered fundamentally important that experimental studies carried out at numerous sites have shown the possibility (and expediency) of using this method to detect and localize hydrogen accumulation centres, as well as to determine the depths of its predicted deposits. In further studies in this direction, it is advisable to pay attention to the types of reservoirs in which hydrogen can be accumulated, as well as seal rocks that will contribute to the preservation of deposits. 

The use of mobile, low-cost direct prospecting methods will significantly speed up the exploration process for natural hydrogen, as well as reduce the financial costs of its implementation.
