Hydrogen Reservoirs

A recent study published in the journal Science reveals the discovery of a large hydrogen gas deposit deep within the Bulqizë chromite mine, in Albania. The findings have sparked optimism among researchers that there may be substantial underground reservoirs of hydrogen capable of meeting global power demands for a low-carbon solution. Hydrogen can be burned without releasing greenhouse gases. 

While hydrogen is the most abundant element in the universe, access to it on Earth has been limited, as it tends to escape into the atmosphere. The existence of natural hydrogen seepages has been known for thousands of years, but it was believed that only small amounts of hydrogen could be found underground. This perception has been challenged in recent years, when significant hydrogen gas reservoirs were discovered in Mali, Europe and South America.

The research team believes that the Bulqizë mine holds 5,000 to 50,000 tons of hydrogen—well short of the millions of tons sought by energy-focused prospectors. Nevertheless, this discovery is confirmation that hydrogen gas can be trapped effectively underground. The technological means to efficiently extract and utilize these reservoirs are still in development.
