The study on identification of natural molecular hydrogen potential in Morocco, conducted for Office National des Hydrocarbures et des Mines (ONHYM), was the first assessment of the potential for natural hydrogen occurrence conducted at a national scale for any country in the world. Field and laboratory work confirmed the occurrence of natural hydrogen in two highly promising areas, with thousands of H2 seeping structures mapped. Further studies are now required to ascertain the potential for producing natural hydrogen from those regions.
