Abstract
Although uncertainties regarding natural hydrogen (H2) reserves remain high, exploration
activity is expanding across several countries. To date, the only active production site uses
this resource locally for electricity generation; however, operating companies could target
industrial markets where H2 can serve as both an energy source and a chemical feedstock.
Surface constraints and proximity to commercial markets will dictate distribution and
utilization strategies when alternative options are available. This study introduces a novel
tool that integrates surface and subsurface constraints to rank prospective exploration
areas, enabling companies to identify opportunities aligned with their specific corporate
profiles or business plans. The methodology is applied to western Colombia, a region
characterized by many surface constraints and known H2-generating source rocks; H2
surface emanations have also been documented. Western Colombia is structurally divided
by north–south mountain ranges (Cordilleras) that severely hinder east–west transportation
and contribute to regional energy insecurity. Using a comprehensive data compilation, this
study demonstrates how applying different weighting schemes to diverse geographical
and geological parameters can optimize site selection. The Medellín area ranks highest if
the target is the industrial market.
