The potential for hydrogen production from three major renewable resources (wind energy, solar energy and biomass) in Argentina is analyzed. This potential for the annual production of wind, solar and biomass hydrogen is represented with maps showing it per unit area in each department. Thus, by using renewable resource databases available in the country, a new Geographic Information System (GIS) of renewable hydrogen is created. In this system, several geographic variables are displayed, in addition to other parameters such as the potential for renewable hydrogen production per department relative to transport fuel consumption of each province or the environmental savings that would imply the production of hydrogen required to add 20% V/V to CNG, with the aim of developing the cleaner alternative CNG + H2 fuel. In order to take into account areas where energy development would be restricted, land use and environmental exclusions were considered. •Potential for renewable hydrogen production in Argentina is analyzed.•Fuel consumption requirement is contrasted with renewable hydrogen potential offer.•Argentina could produce ca. 1 billion metric tons/year of hydrogen from renewables.
