NOVELTY - Providing an energy supply using a renewable energy source (210) involves: providing a first source of renewable energy, where the first source of renewable energy is intermittent or does not provide a sufficient amount of energy; providing energy from the first source of renewable energy to an electrolyzer (410) to produce an energy carrier through electrolysis; selectably reversing the electrolyzer for use as a fuel cell; and providing the energy carrier to the electrolyzer for the production of energy.    USE - For providing an energy supply using a renewable energy source (claimed); and for separated production of gases, including pressurized hydrogen and oxygen.    ADVANTAGE - The method provides sustainable economic development through integrated full spectrum production of renewable energy, which includes the use of an electrochemical or electrolytic cell, and for separated production of gases, including pressurized hydrogen and oxygen that tolerates impurities and products of operation and is reversible; and avoids depletion of natural resources and reduces destructive environmental impact such as pollution and toxic emissions as by-products of production.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for providing a continuous energy supply using renewable energy resources comprising: a first source of renewable energy; an electrolyzer coupled to the first source of renewable energy for producing an energy carrier, where the electrolyzer is configured for selectably reversible operation as a fuel cell using the energy carrier as a fuel; an energy carrier storage coupled to the electrolyzer for receiving the energy carrier from the electrolyzer or providing the energy carrier to the electrolyzer; and an energy storage coupled to the first source of renewable energy and the electrolyzer for selectively receiving energy from the first source of renewable energy and the electrolyzer and for selective providing energy from the first source of renewable energy and the electrolyzer.
