DETAILED DESCRIPTION - The process comprises transforming silicon dioxide-containing (101) or metal oxide-containing starting material into silicon (103) or metal in a reduction process (105), which is provided with a primary energy from a renewable energy source, and then utilizing part of the reaction products (102) of the reduction process in a process for producing methanol (104) with synthesis gas composed of carbon monoxide and hydrogen. The transformation step is a thermochemical or electrochemical transformation. The primary energy for the transformation is supplied by sun light, where a solar thermal plant is used in the case of the thermochemical transformation and a solar plant is used in the case of the electrochemical transformation. The reduction process is carried out at a temperature of 1630 degrees C, in an oxygen-poor or oxygen-free environment, and under the supply of hydrocarbon-containing gases such as methane, biogas or natural gas. The silicon is provided as a first storable and transportable energy carrier and the methanol from the carbon monoxide and hydrogen during the methanol production process is provided as further storable and transportable energy carrier. The energy for the conversion of the hydrocarbon-containing gases is provided from solar energy, where water or water vapor is contacted with the silicon in a first step to provide hydrogen, silicon dioxide and first energy quantity in an hydrolysis reaction and oxygen is contacted with the silicon in a second step to provide silicon dioxide and second energy quantity in an oxygen reaction. The gas oxidation process of the oxygen is carried out under the supply of hydrocarbon-containing gases such as methane, biogas or natural gas, to which synthesis gas composed of carbon monoxide and hydrogen is transformed. The hydrogen is generated in a hydrolysis step and reacts with carbon dioxide to carbon monoxide and water in a further step. In a further step, a portion of hydrogen with the carbon monoxide is converted to methanol. The carbon dioxide is extracted from a combustion process. The process is carried out in an open circuit by carrying out the reduction process in a first place to provide reaction products, transporting the part of the reaction products to a second place and utilizing the part of the reaction products in the second place.
