Definitions
- the invention relates to an electricity generation installation comprising a heat storage.
- thermal storage of an installation according to the invention is inserted between a heat source and a steam power cycle.
- solar power plants include thermal storage, with storage periods of up to 15 hours.
- Storage technologies are essentially based on the sensible heat of materials and are therefore low energy densities, typically between 20 and 50 kWh / m 3 . It being understood that the energy density is the ratio between the useful thermal energy restored to the power cycle and the volume occupied by the storage material.
- Phase change materials such as, for example, nitrate salts, are also studied for their best energy density, between 50 and 100 kWh / m 3 .
- the low conductivity of these materials limits the return power of the stored thermal energy.
- the costs, availability and risks of nitrates can be prohibitive.
- the subject of the invention is an installation for producing electricity from a heat source, making it possible to dissociate electricity production from the use of said heat source over time.
- thermochemical storage device coupled to a cycle of power (CDP)

- thermochemical storage device coupled by mass and / or heat to a power cycle, it becomes possible to shift the electrical production over time to tighter and more interesting periods of time. an environmental or economic point of view.
- thermochemical storage system involves on the one hand a reversible chemical reaction between a solid and a gas (for example: Ca (OH) 2 ° CaO + H 2 O, and on the other hand another monovariant transformation involving the same reactive gas (eg H 2 0 change in liquid / vapor state)
- a gas for example: Ca (OH) 2 ° CaO + H 2 O
- another monovariant transformation involving the same reactive gas eg H 2 0 change in liquid / vapor state
- This method makes it possible to control the operation of the storage and destocking phases, this enthalpy being stored without loss as long as the reagents (CaO and H 2 0 in the previous example) are kept separately, this which allows, for example, to shift the storage and restitution of several days. It is thus possible to carry out a long-term storage of the heat, the losses by sensible heat being negligible
- thermochemical storage device allowing high storage energy densities, typically between 100 and 600 kWh / m 3 of storage material, depending on the nature of the reactive couples, while avoiding the disadvantages noted in the state of the art relating to the availability and risks associated with the storage material.

- the proposed designs allow the operation of a thermal power plant using for example solar energy as external source of heat, driving in a wide range of storage / retrieval scenarios from continuous production day and night, to a production of duration limited during peak periods.
- Thermochemical storage is integrated between the energy source and the steam power cycle. It allows operation of a longer duration than that from the sole use of intermittent energy (solar) or even continuous power cycle.
- the duration of storage could vary between 4h and 10h, while the retrieval period could vary between 1h and 14h.
- thermochemical storage with a power cycle make it possible to reduce, depending on the type of integration envisaged, the amount of heat taken from the source. external, ie the amount of heat released to the environment.
- the proposed integrations thus make it possible, according to proposed configurations, to increase the efficiency, to reduce the size of the solar field in the case of a thermodynamic solar power station, or to reduce the size of the exchangers for heat discharges towards the ambient environment.

STC to the mood).
- thermochemical storage device STC thermochemical storage device
- the heat recovered on this expanded steam can be either sensible (desuperheating the steam) or latent if it condenses directly into the storage reactor (thus removing the condenser from the CDP).

- thermochemical reactor 12 This is to achieve a thermal coupling of the thermochemical reactor 12 and the heat source 1 with the preheater 6 / evaporator 2 / superheater 7 of the power cycle.
- This configuration corresponds to a recovery of the condensation heat of the CDP power cycle to the evaporator 11 of the thermochemical storage STC so that the STC and CDP assembly operates at a higher temperature.
- the CDP cycle operates at higher pressure and thus has improved performance.
- external energy 1 which may for example be solar energy
- a steam generator 2 for operating a conventional Rankine cycle.
- the thermochemical reactor 12 is heated for the decomposition of the reagent.
- Steam produced water vapor in this example
