Definitions

  • the present application relates to methods and systems for providing storable and transportable carbon-based energy sources using carbon dioxide as a carbon source and using electrical energy.
  • Carbon dioxide CO 2 (usually called carbon dioxide) is a chemical compound of carbon and oxygen. Carbon dioxide is a colorless and odorless gas. It is a natural constituent of the air at a low concentration and occurs in living things during cellular respiration, but also in the combustion of carbonaceous substances with sufficient presence of oxygen. Since the beginning of industrialization, the proportion of CO 2 in the atmosphere has increased significantly. The main reason for this is man-made - the so-called anthropogenic - CO 2 emissions. The carbon dioxide in the atmosphere absorbs part of the heat radiation. This property makes carbon dioxide a so-called greenhouse gas (GHG) and is one of the contributors to the global greenhouse effect.
  • GFG greenhouse gas
  • Greenhouse gas (GHG) issuers such as industrial companies (eg car manufacturers) 1 or power plant operators 2, invest or operate, for example, wind farms 3 at other locations as part of balancing projects in order to generate energy without GHG emissions.

  • Numerous companies are trying to buy a "climate-neutral" vest in this way.
  • Wind and solar power plants that convert renewable energy into electrical energy have a transient power output, which greatly complicates a plant operation according to the requirements of an electrical grid and investment and operating costs for additional reserve and frequency control systems requires.
  • the power generation costs of wind farms or solar power plants are substantially increased in comparison to power plants which can directly follow the power requirements of the interconnected grid.
  • carbon dioxide! 5 is used as a carbon source.
  • the carbon dioxide is released taken from a combustion process or an oxidation process of carbon by means of CO 2 separation. It is provided electric DC power.
  • the DC power is largely generated by renewable energy, and it is used to conduct electrolysis to produce 5 hydrogen as an intermediate.
  • the carbon dioxide is then reacted with the hydrogen to convert these products to methanol or other hydrocarbon.
  • a LO transformation of siliceous starting material takes place in a reduction process to silicon, wherein the energy for this reduction process is largely provided by renewable energies. Part of the reaction products of this reduction process is then used in the process for methanol production, in which process for L5 methanol production synthesis gas of carbon dioxide and hydrogen is used, as mentioned.
  • the conversion of silicon dioxide-containing starting material to silicon can be carried out as a supplementary process step to the claimed process or combine with it.
  • the conventional power supply according to the invention becomes particular
  • the electrical energy from wind and / or solar power plants is not fed according to the invention in a network, but directly in a Silicon-Fire plant in storage and transportable forms of energy 5 (preferably converted into hydrocarbons such as methanol). This means that renewable energies are converted chemically into storage and transportable forms of energy.
  • interconnected network can be fed.
  • This feed is optional.

  • the "chemical part" of the Silicon-Fire system can be shut down or switched off relatively quickly and easily, and the decision-making authority is also the responsibility of the operator of the Silicon-Fire system.
  • the energy form can be used, which is provided with the Silicon-Fire system.
  • methanol can be stored in order to be able to provide additional electrical energy in the event of peak energy demand in the electrical grid.
  • methanol may be burned in thermal power plants as needed, or electric power may be generated in fuel cells (for example, direct methanol fuel cells, MFC).
  • the present invention is based on the production of hydrogen by means of electrical energy as far as possible from wind and / or solar power plants in combination with the direct conversion of the hydrogen to a hydrocarbon. Hydrogen is therefore not stored or highly compressed or cooled and transported over longer distances, but serves as an intermediate, which is implemented at the site of its production. According to the invention, an energy conversion process in which solar or wind energy is converted into electrical energy is followed by material-converting (chemical) processes, namely the intermediary provision of hydrogen and the conversion of the hydrogen together with carbon dioxide to a hydrocarbon (e.g., methanol).
