Definitions

  • the invention relates to a method for decarbonizing an industrial site.
  • a method for decarbonizing and/or reducing the CO2 emissions of an industrial site includes the production of hydrogen at the industrial site by water electrolysis, with the electricity required for the water electrolysis being at least partially generated at the industrial site from at least one renewable energy source.
  • the method further includes using the produced hydrogen in at least one industrial application at the industrial site and/or as an energy source for heat and/or power generation at the industrial site.
  • hydrogen is both produced and consumed at the industrial site in a climate-friendly manner. Since hydrogen is an energy carrier that can be used in many different ways, it can make a particularly advantageous contribution to the decarbonization of the industrial site. For example, an external delivery that causes CO2 emissions of the hydrogen required for industrial processes can be avoided or at least reduced. Alternatively or additionally, the hydrogen produced can be used as a climate-friendly energy source to generate heat and/or electricity at the site, so that the site's carbon footprint can be further improved.
  • decarbonization means that there is a change in the way the industrial site is managed in the direction of lower carbon turnover.
  • the industrial site can be a production and/or development site of a company.
  • An industrial application can be understood as any form of industrial processes and procedures that are practice in an industrial context.
  • An industrial application can be a development process and/or production process of an industrial company.
  • the industrial site is a production and/or development site at which a hydrogen drive for vehicles, preferably motor vehicles, is developed and/or produced.
  • the at least one industrial application can include the development and/or production of a hydrogen drive for vehicles, preferably motor vehicles.
  • Hydrogen powertrains may include hydrogen fuel cells and/or hydrogen internal combustion engines.
  • the hydrogen can only be used, for example, for testing a hydrogen drive as part of a development process, for the initial refueling of vehicles that have been produced and/or for refueling as part of test drives.
  • At least part of the industrial water produced and treated at the industrial site is used for the water electrolysis.
  • This offers the advantage that this also means that water is used in an environmentally friendly manner, which Water management relieved, so that less waste water and waste water get into the environment. This further improves the environmental friendliness of the site.
  • Industrial water can be understood, for example, as water contaminated by a production process.
  • Industrial water can be understood, for example, as more general forms of waste water, emulsions and/or waste water that occur at the industrial site, which are treated and/or can be treated by appropriate treatment processes, so that the treated water can be used in water electrolysis.
  • emulsions are used for cooling and chip removal when a tool is engaged, so that industrial water or dirty water is produced, which is contaminated with solid particles, e.g. As aluminum, is enriched.
  • solid particles e.g. As aluminum
  • all other forms of waste water are also conceivable, such as are conceivable in a wide variety of applications, for example cleaning systems, at an industrial site. This can also be understood to mean the use of rainwater, which can be collected at the industrial site.
  • groundwater present at the industrial site is used for the water electrolysis.
  • the use of groundwater relieves the water supply from external sources and reduces the costs for the use of fresh water from a public supply. This further improves the environmental friendliness of the site.
  • Groundwater can in particular include the use of well water, which can be drawn from local wells at the industrial site. Groundwater can also be treated for use in water electrolysis.
  • the treatment of the industrial water and/or the groundwater can include the following steps: cleaning the water in a vacuum evaporator system, reverse osmosis and full desalination and/or deionization using a full desalination system.
  • the method further comprises using oxygen produced by the water electrolysis in at least one industrial application at the industrial site, for example in welding applications.
  • oxygen is used to burn the fuel gas, such as methane, argon, propane or hydrogen.
  • the use of the produced or excess hydrogen as an energy source for heat and/or electricity generation at the industrial site includes the use of at least part of the produced hydrogen for environmentally friendly heat and/or electricity generation by a power plant with combined heat and power located at the industrial site -Coupling, CHP.
  • the power plant can preferably be designed as a combined heat and power plant.
  • the innovative combined heat and power plant offers very high flexibility in power generation and is used individually when there are fluctuations in the power grid. Power is preferably generated to cover the peak loads in the power grid.
  • Power plants with combined heat and power use the simultaneous generation of mechanical energy and usable heat.
  • Power plants using cogeneration can include gas turbines, internal combustion engines and fuel cell systems. The advantage of such systems is that they can save up to a third of the primary energy compared to the separate generation of electricity and heat. Such systems are therefore particularly environmentally friendly.
  • the method comprises mixing part of the hydrogen produced with methane and temporarily storing the resulting hydrogen-methane mixture in an intermediate fuel store, e.g. B. in a pressure-resistant cryogenic tank in the liquid state and supplying the temporarily stored hydrogen-methane mixture as fuel to the power plant with combined heat and power.
  • an intermediate fuel store e.g. B. in a pressure-resistant cryogenic tank in the liquid state
  • a hydrogen-methane mixture as fuel for the power plant at the industrial site also allows the use of power plants designed for methane as fuel.
  • a hydrogen content of 30% is not exceeded.
  • the hydrogen produced can be used directly as fuel.
  • an emergency hydrogen supply can be set up, e.g. B. can ensure a hydrogen supply in the event of a failure of a hydrogen supply by water electrolysis.
  • a supply by an external supplier can e.g. B. via the delivery of liquid hydrogen in tanks.
  • the method comprises a methanation of carbon dioxide generated as exhaust gas from the power plant with combined heat and power using the hydrogen produced at the industrial site.
  • the CO2 emissions into the environment generated by the power plant are thus at least partially reduced according to this embodiment variant in that the CO2 generated is converted to methane by means of methanation and the methane generated is then fed back to the power plant as fuel. This can make a further contribution to the decarbonization of the site.
  • the method can optionally include using the methane produced by the methanation for mixing with part of the hydrogen produced and/or intermediate storage of methane produced by the methanation in the intermediate fuel store.
  • the methanation process is known per se from the prior art and does not need to be described in more detail here.
  • systems and catalysts known from the prior art can be used for separating the carbon dioxide from the exhaust gas of the power plant and for methanizing the carbon dioxide.
  • the fuel can also be supplied to the power plant of the industrial site without intermediate storage of the fuel mixture in an intermediate fuel store.
  • both pure manufactured Hydrogen as well as hydrogen produced which is mixed with methane when supplied, are supplied to the power plant.
  • the methane used for mixing can be provided both from methanation and from an existing external supply of methane. Simultaneous procurement from both methane sources is also possible.
  • the methane that comes from the external feed is preferably biomethane (synonymous with bio natural gas).
  • Biomethane is methane that is not of fossil origin but was produced from biogenic substances and is a component of biogas. This can make a further contribution to the decarbonisation of the site.
  • a hydrogen content of 30% is preferably not exceeded.
  • the method can be designed such that methane can be supplied to the power plant, both from external sources and from methanation, without prior mixing with hydrogen produced, both in the embodiment variant with and without intermediate fuel storage. This offers the advantage that operation of the power plant can be ensured even if hydrogen production fails or there is insufficient hydrogen production at the site.
  • the method can also include feeding heat and/or electricity generated by the cogeneration power plant located at the industrial site and not required at the industrial site into a public heating and/or electricity grid.
  • heat contained in the waste gas of the power plant can be at least partially recovered, e.g. B. by means of a heat exchanger, and used at the industrial site. This can make a further contribution to the decarbonisation of the site.
  • utilization of the power plant with combined heat and power generation can be actively controlled to stabilize or to compensate for fluctuations in the demand of the public heating and/or electricity network.
  • public heating and/or electricity grids are increasingly subject to greater fluctuations in demand, resulting from fluctuations in the supply of renewable energies (wind, sun, biomass, etc.), whose share in electricity and heat generation is constantly increasing.
  • the generation of hydrogen from at least one renewable energy source according to the invention allows an advantageous decoupling of these supply fluctuations to be achieved since the hydrogen produced can be temporarily stored. If there is now an undersupply in the public electricity and/or heat network, the capacity utilization of the power plant can be increased in order to increase the electricity and/or heat fed into the public network. If there is an oversupply in the public grid, the utilization of the power plant can be reduced accordingly.
  • the power plant can contribute to the stabilization of a public electricity and/or heating network.
  • waste heat generated in the production of hydrogen by water electrolysis can be fed into a local heating network at the industrial site.
  • the waste heat can preferably be obtained by means of a first heat exchanger from the hydrogen produced and/or by means of a second heat exchanger from oxygen produced by the water electrolysis.
  • heat can also be extracted from the heat obtained by the water electrolysis via a heat pump, e.g. B. for high-temperature networks.
  • a heat pump e.g. B. for high-temperature networks.
  • a proton exchange membrane (PEM) electrolyzer can be used for the water electrolysis.
  • a PEM electrolyser offers the advantage that it generates a relatively high output pressure of the products hydrogen and oxygen (up to 50 bar), so that less energy is required for any subsequent compression processes.
  • the PEM electrolyser works between room temperature and 80 °C, so that no particularly temperature-resistant materials are required and it can still be used as a waste heat source.
  • the modular design of PEM electrolysers is particularly advantageous, so that simple expansions of a system are possible and a system can be set up piece by piece.
  • Another great advantage of the PEM electrolyser is the short start-up times (5 to 10 minutes) and the large partial load capability (5% to 100% of the possible output), which, in combination with a renewable energy source, such as e.g. B. a photovoltaic system, are particularly advantageous. Therefore, a PEM electrolyzer is particularly advantageous compared to a high-temperature electrolyzer or an alkaline electrolyzer.
  • a nitrogen supply facility and/or compressed air supply facility provided on the industrial site can be used in at least one industrial application at the industrial site and in addition to cleaning the proton exchange electrolyser, preferably cleaning its proton exchange membrane , be used.
  • an existing nitrogen supply device such as this z. B. is used to provide inert gas in welding processes, can also be used to clean the electrolyser. This saves costs and indirectly makes a further contribution to the decarbonization of the industrial site through the double use of a nitrogen and/or oxygen system.
  • compressed air from the compressed air supply device is used additionally or exclusively for controlling the PEM electrolyzer. Advantages arise according to the above embodiment.
  • Compressed air is required to regulate the pneumatic control valves of the PEM electrolyser.
  • the control valves are used on both the water and the gas side. The advantage here is that the infrastructure already exists and can continue to be used in the electrolysis process.
  • a cooling water circuit provided at the industrial site can be used in at least one industrial application at the industrial site and additionally used to cool the hydrogen and/or oxygen produced by the water electrolysis.
  • a cooling circuit can advantageously be used twice at the industrial site and thus indirectly make a further contribution to the decarbonization of the industrial site.
  • the electricity required for the water electrolysis is generated from at least one renewable energy source at the industrial site.
  • this electricity is generated by means of a photovoltaic system and/or wind power plant arranged at the site and is at least partially temporarily stored in a store for electrical energy.
  • other regenerative energy sources e.g. biomass, geothermal energy, etc.
  • the electricity required for the water electrolysis can also be obtained from a public electricity network if required.
  • a water electrolysis fed by it can also be carried out when an intermediate power storage device is discharged or not enough electricity can be produced locally.
  • figure 1 shows a schematic process sketch for the production of hydrogen at the industrial site by water electrolysis and a use of the hydrogen produced in at least one industrial application and for heat and power generation.
  • the industrial site 100 is merely an example of a production and development site at which hydrogen drive systems for motor vehicles are developed and produced.
  • the industrial site is indicated here schematically by the area surrounded by reference number 100, within which, in addition to industrial processes 30, such as the development 30a and production 30b of a hydrogen drive, hydrogen is also produced and used locally, which is explained below.
  • water electrolysis describes the splitting of water (H 2 O) into the components hydrogen (H 2 ) and oxygen (O 2 ) by supplying electricity, two parts of the hydrogen product and one part of the oxygen product being produced.
  • the corresponding reaction equation is as follows: 2 *H2O ⁇ 2 *H2+ O2
  • a photovoltaic system 7 arranged at the industrial site generates electricity 3 from solar energy at the industrial site.
  • This stream 3 is used for water electrolysis 11.
  • the regeneratively generated electricity 3 can be temporarily stored in an electrical energy store 8 or fed directly to the electrolyser of the water electrolysis 11 .
  • the electrolyzer is a PEM electrolyzer 11.
  • electricity 3 from the public power grid 6b can also be fed to the PEM electrolyzer 11.

  • the water 12 is at least partly industrial water and/or groundwater that occurs at the industrial site and that is appropriately prepared beforehand for use in the water electrolysis. This is below in connection with figure 2 described in more detail.
  • the compressed air 16 is used to control the PEM electrolyzer 11 and the nitrogen 17 to clean the PEM electrolyzer 11.
  • the membranes of the PEM electrolyzer can be cleaned with the nitrogen 17 11 to be cleaned.
  • hydrogen 1 and oxygen 2 can be produced by splitting the water molecule.
  • Heat 4 is extracted from the PEM electrolyzer 11 and the hydrogen 1 produced via a first heat exchanger 15a and from the oxygen 2 produced via a second heat exchanger 15b. In figure 1 this is shown in a simplified way. The heat 4 is withdrawn from the hydrogen 1 and the oxygen 2 in a drying process.
  • An exemplary realization (only partly in figure 1 shown) provides that the hydrogen produced coming from the electrolyzer runs through a hydrogen separator (not shown) in which water is separated from the moist hydrogen.
  • heat is removed from the separated hydrogen, which still contains residual moisture, by means of the first heat exchanger 15a.
  • the cooled hydrogen then enters a hydrogen dryer (not shown), which removes any residual moisture from the hydrogen. From there, a resulting stream of water returns to the hydrogen separator.
  • the dried hydrogen from the hydrogen dryer is then compressed in the next step, and the compressor can have any number of compression stages.
  • the work introduced into the hydrogen and the associated heating of the hydrogen is withdrawn again by means of a cooling circuit before the hydrogen is stored in the hydrogen storage device 13 .
  • the cooling circuit will be discussed again in a later section.
  • An analogous process chain optionally results for the oxygen produced, with the second heat exchanger 15b being used in order to extract heat 4 from the oxygen, and no compressor being used before the oxygen 2 is stored in suitable oxygen reservoirs (not shown).
