The possibility of using indigenous renewable energies for electrolytic hydrogen production in Crete has been investigated. Hydrogen can be used for de-carbonization of the transportation sector in the island replacing all existing conventional vehicles with fuel cell electric vehicles. The required H2 has been estimated as well as the electricity needed for its production via water electrolysis. Solar and wind energy is currently used for electricity generation with solar-PV systems and wind farms in Crete generating a significant amount of the island’s electricity consumption. The size and the cost of the solar-PV systems and the wind farms required for electricity generation, needed in electrolytic H2 production, have been estimated. The hydrogen required for powering all fuel cell vehicles in Crete has been estimated at 53,037 tonsH2/year and the electricity required for its electrolytic production at 3,826,563 MWh. The size of the solar-PV systems generating the electricity required in water electrolysis is estimated at 2,710 MWp while their cost at bil.$ 3.25.  The size of the wind farms generating the electricity required in water electrolysis is estimated at 1,501 MWel while their cost at bil.$ 1.50.  It is concluded that local renewable energies can be used for electrolytic H2 production in Crete although their installation cost is high. The results can be used for the creation of a roadmap regarding the de-carbonization of the island’s transportation sector.
