Exploring Hydrogen-Gas Reservoir

Feasible to have the existence of natural hydrogen-springs? Particularly, at a relatively shallower depths?

Feasibility of hydrogen gas getting explored in conjunction with any other liquid?

Whether the pressure forces which will be forcing the hydrogen up the well would possibly result from the same hydrogen gas contained in the hydrogen-sand in the immediate vicinity of the well or at a considerable distance way?

How about the porosity and homogeneousness of the geological formation which would serve as a reservoir to hold the hydrogen gas?

How about the existence of a porous rock to serve as a reservoir?

Whether the location of drilling wells are to be based on conventional anticlinal theory, or, on synclines as well?

What would be general areal/volumetric extent overwhich the strata above or below the hydrogen gas geological formation would remain cracked?

What would be the (intensity of dip / general dip / local dip / maximum dip) dip of the hydrogen-gas formation and the respective positions of anticlines and synclines?

What would be approximate range of pressures under which hydrogen gas will be existing before being tapped by wells?

What would be the relative proportion of the hydrogen gas and any other liquid and/or gas that will be contained in the hydrogen gas geological formation?

How complex would be the deduction and analysis of columnar structure of the hydrogen gas geological formation that could possibly be revealed by the study of the outcropping rocks and the drilling of hydrogen wells as against the investigations on the horizontal structure of the hydrogen gas geological formation?

Despite all the above investigations, whether, hydrogen gas will remain available in commercial quantities that is not exclusively confined to them (assuming that the origin of hydrogen gas has an important bearing upon its economic geology)?
