Helium is a noble gas. It is the smallest of all known elements, the second lightest, and has the lowest boiling point -269°C.

As helium is lighter than air, it is actively being lost into space. However helium is also actively being created via the decay of naturally occurring radioactive elements in rocks over vast periods of time. The produced helium is liberated and carried in groundwater.

This is the setting for Helium One’s projects, where the released helium has been transported by groundwater and can accumulate in porous geological formations such as sandstone.

As a high-value product, liquid helium can be transported to port via ISO containers mounted onto trucks with no pipelines being necessary.
