| 摘要 |
The invention relates to a method for temporarily storing energy, wherein iron ore is reduced with hydrogen and the thus obtained intermediate product of reduced iron ore and optional accompanying substances is metallurgically processed, the hydrogen being produced by the electrolysis of water and the electrical energy required for electrolysis being regenerative energy, which stems from water power and/or wind power and/or photovoltaic power or other regenerative energy forms. The hydrogen and/or the intermediate product is produced independently of the current demand whenever sufficient regeneratively generated electrical energy is available. Any quantity of intermediate product not demanded is stored until demanded/used so that the regenerative energy accumulated therein is also stored. The invention also relates to a method for storing discontinuously generated energy, the discontinuously generated energy being supplied, when available or once it has been generated, to a process in which a storable intermediate product is produced from a starting material and the storable intermediate product is stored until it is required or demanded for production of a final product. |
