NOVELTY - Method of making a fuel comprising a nitrogen-based compound, comprises: (a) producing hydrogen and metal hydroxide by electrolysis of an aqueous solution containing a metal chloride; (b) exposing the metal hydroxide obtained by the electrolysis to an atmospheric fluid flow to sequester carbon dioxide from the atmosphere and produce at least one of metal carbonate and metal bicarbonate; and (c) reacting nitrogen with the hydrogen produced from the electrolysis to form ammonia.    USE - The method is useful for making a fuel comprising a nitrogen-based compound, which is useful for the transport and/or in propulsion systems.    ADVANTAGE - The method provides nitrogen based fuels, which does not: exacerbate the problem of global warming; and burn until water and excess engine heat are added for hydrolysis, thus provides valuable safety benefits to the automotive and aero industries. The method allows valuable mineral exploitation without the need to re-bore entrance holes into the coal seam or conduct additional extensive geological surveys.    DETAILED DESCRIPTION - Method of making a fuel comprising a nitrogen-based compound, comprises: (a) producing hydrogen and metal hydroxide by electrolysis of an aqueous solution containing a metal chloride, where the solution comprises components of water, sodium chloride, potassium chloride, magnesium chloride, sea water, salt well brine and/or calcium chloride; (b) exposing the metal hydroxide obtained by the electrolysis to an atmospheric fluid flow to sequester carbon dioxide from the atmosphere and produce at least one of metal carbonate and metal bicarbonate; and (c) reacting nitrogen with the hydrogen produced from the electrolysis to form ammonia.
