TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The process (P1) further involves using electricity produced from the renewable energy resource to reduce an amount of carbon dioxide to a first amount of carbon monoxide and oxygen. In the process (P1), the producing hydrogen is done by electrolysis of water using electricity generated from the renewable energy resource (R1), and the renewable energy resource (R1) comprises wind or solar energy. The producing hydrogen further involves producing oxygen as a by-product and using the oxygen in a downstream process. The carbon monoxide and produced hydrogen are converted to at least one of methane and methanol via a catalytic process. The oxygen is utilized in the gasification of a carbon feedstock to produce a second amount of carbon monoxide, and where the second amount of carbon monoxide is utilized in a downstream process. When the produced hydrocarbon material comprises methanol, and then the method further involves converting the methanol to at least one of the group consisting of aromatic hydrocarbons and/or olefins. The produced hydrogen is reacted with carbon monoxide in presence of the recovered carbon dioxide to produce methanol. When the produced hydrocarbon material comprises methane, and then the method further involves converting the methane to methanol, where the methane is then converted into at least one of syngas, second hydrogen supply, carbon monoxide and methanol. The methane is converted into at least carbon monoxide and the second hydrogen supply, where the carbon monoxide is directed for use in the production of methanol, and where the methanol is produced by reacting the carbon monoxide and at least one of the produced hydrogen from the renewable energy resource and the second hydrogen supply in presence of the recovered carbon dioxide. When the produced hydrocarbon material comprises methane, and then the method further involves converting the methane into at least one of the group consisting of syngas, components of syngas, hydrogen, and carbon monoxide, and using the hydrogen or carbon monoxide from the converting of methane, if present, to produce methanol. Preferred System: In the system (S1), the second element comprises an electrolytic cell for the electrolysis of water for producing hydrogen using electricity generated from the renewable energy resource (R1). When the produced hydrocarbon material comprises methanol, and then the system further comprises a fourth element for converting the methanol to at least one of aromatic hydrocarbons and/or olefins. When the produced hydrocarbon material is methane, and then the system further comprises a fourth element for converting the methane to methanol. Preferred Components: The waste stream or industrial element comprises an exhaust gas from a gas turbine engine. EXAMPLE - No suitable example is given.
