Definitions

  • the invention relates to a method and an arrangement for storing energy in the form of liquid air, with which preferably electrical energy can be stored during off-peak periods of a power grid and removed again during peak load periods.
  • pumped storage power plants can achieve relatively high efficiencies of up to 80%, they can only be installed at a few suitable locations, their size largely being determined by local conditions (not scalable).
  • the invention has for its object to find a method with the comparatively inexpensive energy stored and removed again can, with a very high number of operating cycles should be achievable.
  • the process should allow total efficiencies of 50% or more.
  • the method should be feasible regardless of the geographical conditions at the place of use.
  • the system should be able to be realized in a relatively simple, modular construction of individual components available according to the prior art.
  • the inventive method for storing energy is divided into two phases (steps). In the first phase, energy available in excess is transferred into a storable form and stored (storage). In the second phase, if additional energy is needed, the stored energy is removed again (removal).
  • air is drawn in at the inlet (suction side) of a single or multi-stage compressor and the pressure of the air raised to a value higher than the ambient pressure, the air liquefied by means of an isenthalpic expansion and finally a thermally insulated storage tank fed.
  • the energy supplied to the compressor is thus transferred into a storable form, namely liquid air, which can be easily stored in a cryogenic tank.
  • the compressed air is cooled by cold steam.

Agencement pour le réalisation d'un procédé selon la revendication 1, avec un compresseur à un ou plusieurs étages avec un refroidissement intermédiaire (1), où un échangeur de chaleur à contre courant (2) est mis à contribution au niveau du dernier étage du compresseur, dont un côté peut être traversé par un flux d'air comprimé et dont l'autre côté peut être traversé par un flux de vapeur froide ; une turbine de détente et de liquéfaction (4) par laquelle un deuxième flux massique constitué par l'air sortant de l'échangeur de chaleur à contre courant (2) peut être mené ; un échangeur de chaleur de Claude (3), qui sert à l'échange de chaleur entre le flux massique sortant de la turbine de détente et de liquéfaction (4), ainsi qu'entre la vapeur froide générée par ailleurs lors du processus de liquéfaction de l'air, et un premier flux massique ; une soupape de détente (5), par l'intermédiaire de laquelle le premier flux massique peut être détendu de manière isenthalpique jusqu'à une pression de liquéfaction ; un séparateur de phases (6) dans lequel l'air liquéfié peut être séparé de l'air sous forme de gaz ; un réservoir de stockage (7) isolé thermiquement qui sert à stocker l'air liquéfié ; une unité de regazéification qui est installée pour augmenter la pression de l'air liquide prélevé à partir du réservoir de stockage (7) et à amener la température de l'air jusqu'à au moins la température de l'environnement ; une turbine principale (12) qui peut être entraînée par l'air sous pression généré dans l'unité de regazéification, où l'agencement comprend une machine de Rankine (9) à un ou plusieurs étages qui sert à la réalisation du processus de Rankine, où l'étage le plus bas de la machine de Rankine (9) est couplé thermiquement à l'unité de regazéification au moyen d'un échangeur de chaleur à contre courant dont un coté est branché entre la sortie du réservoir de stockage et l'entrée de la turbine principale (9) et dont l'autre côté peut être traversé par le flux du produit de refroidissement employé dans la machine de Rankine.
  9. Agencement selon la revendication 8, caractérisé en ce que le compresseur (1) est entraîné électriquement et, à la fois la turbine principale (12) et la turbine de Rankine (14), sont chacune couplées à un générateur électrique (13, 18), grâce auquel l'agencement est approprié pour l'accumulation d'énergie électrique.
