The present invention relates to a method of production of a fuel containing at least one hydrocarbon from a biomass, comprising the steps of: -A) chemical decomposition of the biomass in a solvent to at least one chemical intermediate compound chosen from the group consisting of a hexose, a pentose and a derivative of lignin, or a combination thereof, optionally produced together with at least one other target chemical, to form a first solution; - B) complete reduction of the first solution with a reducing agent to at least one hydrocarbon to form a fuel; wherein the steps A) and B) are performed below 300.degree.
