Definitions
- the invention relates to a storage power plant according to the preamble of independent claim 1 and a method for charging and discharging the energy storage devices of such a storage power plant according to the preambles of claims 5 and 6.
- renewable energies such as solar and wind energy
- thermal energy storage (often also referred to as heat storage) is already state of the art in solar thermal power plants.
- the charging of the thermal energy storage with solar energy is primarily fluid-based (e.g. using thermal oil).
- This concept can generally be transferred to storage power plants, whereby the thermal energy storage can also be charged using electrical energy or other fluid-bound heat flows (e.g. waste heat from industrial processes). Waste heat is excess heat (e.g. from an industrial process) that would otherwise be released into the environment unused.
- the maximum operating temperature of the thermal energy store varies depending on the type of energy flows during charging and the design of the thermal energy store.
- the (re)conversion of the stored energy takes place by means of a generator-bound steam turbine in a water-steam cycle.
- the temperature of the thermal energy storage thus influences the fluid temperature of the water-steam circuit.
- the use of the steam turbine requires minimum fluid parameters at the turbine inlet (minimum temperature in Dependency of the pressure) below which operation is not possible due to excessive wetness in the expansion process. Operation above the minimum fluid parameters (temperature increase or combined temperature and pressure increase) is possible within certain limits (until the maximum fluid parameters are reached) and can lead to increased circuit efficiency.
- thermal energy storage devices cannot currently be used as long-term storage devices.
- Chemical energy storage is more suitable for long-term storage than thermal energy storage.
- excess electrical energy can be used to generate hydrogen using electrolysis.
- the hydrogen can be burned in a hydrogen-fired gas and steam power plant for reverse flow.
- chemical energy storage devices have the disadvantage of higher electricity generation costs. Consequently, the upgrading of thermal energy storage to long-term storage has great economic potential.
- the object of the present invention is to provide a storage power plant with improved storage technology. Furthermore, it is the object of the present invention to show methods for charging and discharging the energy storage devices of such a storage power plant.
- the storage power plant comprises at least one water-steam circuit, the water-steam circuit comprising at least one steam turbine with a generator that is operatively connected to the steam turbine, and two energy storage devices.
- the energy storage devices are arranged and designed in such a way that they can deliver energy to the H2O flowing in the water-steam circuit in order to generate steam with defined steam parameters.
- H20 also referred to below as the working medium of the water-steam cycle, generally stands for water in different aggregate states (liquid, vapor).
- the steam that can be generated can be expanded in the steam turbine, with the rotational energy produced during the expansion of the steam being usable for driving the generator.
- the first energy store is designed as a thermal energy store and the second energy store is designed as a chemical energy store.
- the chemical energy storage device can be charged using electrical energy and includes an electrolyser for separating water from the water-steam cycle into hydrogen and oxygen and a first storage device for storing the hydrogen and a second storage device for storing the oxygen.
- the water-steam circuit includes a steam generator for the internal combustion of the hydrogen with the oxygen, the steam generator having a connection via which the steam that can be generated in the steam generator, H 2 O, can be fed for steam conditioning.
- the steam generator used for internal combustion is hereinafter referred to as Clean Steam Generator, CSG for short.
- the CSG generates water vapor through pressurized internal combustion of hydrogen and oxygen. This primarily generated water vapor is conditioned by the addition of H 2 O. This conditioned water vapor is described below referred to as CSG vapor. Chemical reactions can take place during conditioning.
- the storage power plant according to the invention thus combines the advantages of thermal energy storage with those of chemical energy storage's rule.
- Thermal energy storage devices gradually lose their stored energy over time due to heat losses, but hydrogen and oxygen can be stored with low time-dependent losses, which makes these substances a suitable storage medium for long-term energy storage devices (chemical energy storage devices, power to Eh & O 2 ).
- the storage power plant according to the invention can play a decisive role in power grids with a high proportion of volatile power sources (renewable energies).
- the energy stores thermal energy stores, chemical energy stores
- the chemical energy storage offers some advantages in terms of operational flexibility, e.g. through CSG
- the main advantage of the storage power plant according to the invention lies in the rare event of longer-term electricity production in the grid (eg dark lull, longer period without sunshine and wind). Due to the low time-dependent losses of the chemical energy store, the stored energy can be reliably discharged even after long downtimes, which means that the storage power plant also supplies a minimum amount of energy that can be planned in this case. Since her storage power plant according to the invention can be used in contrast to purely thermal storage power plants for long-term storage. However, the electricity production costs in the storage power plant according to the invention are lower than in a storage power plant with purely chemical energy storage. Through the targeted adjustment of the respective proportion of the two storage principles (thermal and chemical mixed), an individually optimized storage power plant can be achieved.
- An embodiment of the storage power plant according to the invention is characterized in that the water-steam circuit is designed as a closed circuit.
- the water required for the electrolysis is taken from the condensate of the water-steam cycle (mass balance is closed due to the internal combustion of the hydrogen and oxygen produced in the CSG).
- This closed circuit is an essential difference to other systems, e.g. storage power plants based on a gas turbine, which is fired with hydrogen from the electrolysis. There, the water is lost through the chimney, which leads to a significant water consumption.
- a further embodiment of the invention provides that the thermal energy store has a connection for supplying fluid-bound heat.
- This makes it possible to charge the thermal energy store additionally or alternatively (for electrical charging) by means of a fluid.
- a fluid can be, for example, thermal oil, which is heated by a solar thermal power plant and/or by waste heat from industrial processes.
- a possible difference in temperature of the working medium between the outlet of the thermal energy storage unit and the target parameters at the inlet to the steam turbine is compensated for by admixing CSG steam.
- a further embodiment of the invention provides that the connection on the CSG is actively connected to the capacitor and/or the thermal energy store.
- water and/or water vapor can be sprayed into the CSG and the vapor parameters of the CSG vapor can thus be adjusted.
- the water discharged from the capaci tor is first supplied to a preheater and then feeds the heated water to the CSG.
- the preheater can be operated, for example, by means of intermediate steam extraction from the steam turbine.
- the energy stores are generally and preferably charged at times when there is an oversupply of electrical energy.
- Part of the electrical energy is used to heat up the thermal energy store (power to heat).
- the energy can be introduced into the thermal energy store via fluid-bound heat, for example by means of waste heat introduction.
- Another part of the electrical energy is stored in the chemical energy store.
- water is broken down into hydrogen and oxygen by means of electrolysis and then stored in reservoirs (e.g. pressure tanks). How large the respective proportion of electrical energy is for charging the respective energy store can vary, even during the charging process, whereby a customer-optimized solution with low electricity production costs should be aimed for.
- the above-mentioned proportions of the electrical energy that is used to charge the respective energy store can also be zero, independently of one another.
- the water that is fed to the electrolyzer is preferably taken from the water-steam circuit. This results in a closed cycle, which means that the process can be operated without any significant water consumption (only a small amount of water to compensate for leaks). gene may be necessary) and the process is particularly suitable for use in dry regions.
- the water required for the electrolysis is recovered from the condensate of the water-steam cycle (mass balance is closed due to the internal combustion of the hydrogen and oxygen produced in the CSG). This closed cycle is a major difference compared to known methods.
- the inventive method for discharging the Energyspei cher a storage power plant according to one of claims 1 to 4, is characterized by the following process steps:
- thermal energy is transferred from the thermal energy storage device to the working medium in the water-steam circuit in order to bring about a temperature increase and/or phase change (evaporation).
- hydrogen and oxygen from the respective storage device oxygen storage device/hydrogen storage device
- Working medium is also injected into the CSG to condition the vapor produced during combustion.
- the working medium is primarily dem Water-steam circuit removed and can be pre-heated by regenerative pre-heating or by the thermal Energyspeieher.
- a possible temperature difference of the working medium between the outlet of the thermal energy storage device and the target parameters at the inlet to the steam turbine is compensated for by admixing CSG steam.
- the mode of operation division of energy flows and temperature levels between thermal energy storage and chemical energy storage
- the location of the steam injection depend on the respective application.
- thermal energy storage devices with temperature levels below the target temperature at the steam turbine inlet can therefore also be used for reverse flow by means of conventional water-steam circuits. No other energy sources are required, which leads to higher net electricity generation and self-sufficiency.
- the storage power plant can be operated even more flexibly thanks to the hot water/intermediate steam extraction.
- the warm water/steam can also be taken directly from the thermal energy store.
