Definitions
- the invention relates to a metallurgical production plant, in particular an integrated metallurgical plant with an integrated steel plant, with consumers being present for electrical energy and/or for hydrogen.
- the invention also relates to a method for operating such a metallurgical production plant.
- the known metallurgical production plants typically buy their required electrical energy on the market and receive this via external power supply networks.
- the generation of electrical energy is traditionally based on fossil fuels or so-called nuclear energy.
- fossil fuels or so-called nuclear energy.
- a combustion reaction produces dust and CO2. The latter is responsible for global warming.
- a further disadvantage of the forms of energy mentioned and used traditionally is their storage capacity, which is only possible to a limited extent, and their reconversion into the same primary energy for the construction of an energy store, which is only possible with great effort.
- a method for producing steel is known in the prior art, for example from European Patent Specification EP 2 895 631 B1, in which iron ore is reduced with the aid of hydrogen and the intermediate product thus obtained from reduced iron ore and optionally accompanying substances is further processed metallurgically.
- the hydrogen is produced by electrolysis of water on the premises of a metallurgical plant i produced, the electrical energy required for the electrolysis being regenerative energy, which comes from hydroelectric power and/or wind power and/or photovoltaics or other regenerative forms of energy. Irrespective of the current demand, the hydrogen and/or the intermediate product are always generated when sufficient renewable energy is available.
- fuel cells are known in the prior art for generating electricity from a chemical reaction of hydrogen and oxygen. In addition to electricity, only heat and water are produced as end products.
- the chemical reaction within the fuel cell corresponds in principle to the so-called oxyhydrogen reaction, in which a mixture of hydrogen and oxygen is made to explode. In a fuel cell, however, the released energy does not fizzle out, but is converted into electrical energy. Fuel cells do not produce any harmful exhaust gases at the place where they are used.
- the invention is based on the object of further developing a known metallurgical production plant and a method for its operation, in which fossil fuels are already replaced by hydrogen produced in an environmentally friendly manner using an electrolysis device, such that the electrical energy for various consumers within the metallurgical production plant is also environmentally friendly provided.
- the metallurgical production plant according to the invention is characterized in that one of the consumers of hydrogen is a fuel cell for generating electricity from the hydrogen stored in the hydrogen store.
- the term "metallurgical production facility” means a metallurgical plant, preferably an integrated metallurgical plant, more preferably with integrated crude steel production and an integrated steelworks.
- hydrogen also includes hydrogen mixtures.
- renewable energy source includes all types of generating electricity from renewable energy, such as a wind turbine, a hydroelectric power plant, a solar power plant, etc.
- the claimed metallurgical production plant provides a coupled infrastructure of the energy sources “hydrogen” and "electrical energy”.
- a fuel cell and an electrolysis device which are coupled to one another via a hydrogen tank, both forms of energy, hydrogen and electricity, can be converted into one another as required and can thus be provided quickly and easily.
- the aspect "Hydrogen 1" within the metallurgical production plant according to the invention includes the generation of hydrogen with the help of electrical energy that is preferably provided regeneratively by electrolysis of water, the storage of the hydrogen produced in this way or of the hydrogen delivered by external providers by truck or train in the hydrogen storage tank, the optional Recovery of electrical energy from the hydrogen reactions within the fuel cell and the distribution of the hydrogen via the pipeline network located on the factory premises to the fuel cell and/or other direct consumers of the hydrogen within the metallurgical production plant.
- the hydrogen store is the central energy reservoir for the metallurgical production plant according to the invention.
- the aspect of "electrical energy" within the metallurgical production plant relates to its provision with the help of the fuel cell from the stored hydrogen and the use of the electrical energy obtained in this way by electrical consumers, particularly within the metallurgical production plant.
- the metallurgical production plant has a power grid located on the factory premises and the fuel cell can be coupled to it on the output side in order to feed in the electricity it provides, preferably when the demand for electrical energy in the production plant is particularly high.
- the external energy supplier of the metallurgical plant then no longer has to react to peak loads, for example when an electric arc furnace in the metallurgical production plant is switched on, because the peak loads can then be covered by the electrical energy provided by the fuel cell.
- the metallurgical production plant advantageously has its own electrical energy source, which it can access at any time as required, without having to consider the peak load times of the external energy supplier.
- other, preferably regenerative, energy sources can also be present on the factory premises, which can also be connected to the factory's own electricity network in order to feed electricity there.
- the connection of both the fuel cell and the other regenerative energy sources to the power grid located on the factory premises is advantageously carried out with the interposition of a grid synchronization device. This coordinates the feeding into the power grid as required at certain times and in certain situations.
- Both the operator of the metallurgical production plant and the energy supplier of the production plant can benefit from intelligent energy management that takes both hydrogen and electrical energy into account.

- the current generated in this way is preferably fed into a power grid 140 located on the factory premises, with an inverter 150 and possibly a transformer being connected in between. If there is excess electricity capacity, the electricity generated by the fuel cell can alternatively also be fed into an external electricity supply network 160 via the electricity network 140 on the factory premises, preferably with the interposition of a network synchronization device.
- the heat generated by the fuel cell 132 is used within the metallurgical production plant 100 by, for example, via a heat pipe network 190 located on the factory premises to heat consumers within the metallurgical production plant, such as. B. to heated buildings or service water heaters. Alternatively or additionally, the generated heat can also be given off to an external heating network.
