  • 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, with their size being largely determined by the local conditions (not scalable).
  • the invention has for its object to find a method with the comparatively inexpensive energy stored and can be removed again, 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 For storing energy, preferably electrical energy, 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 is liquefied by means of 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.

  • the pressure increase can in principle be mechanical, z. B. by means of a piston pump, done, but the required (electrical) energy leads to a reduction in the overall efficiency of the process.
  • the pressure of the air is only increased thermally by increasing the temperature of the air in a sealed vessel until it has reached the required process pressure. Subsequently, the temperature of the air at ambient temperature, or if a waste heat source is available, brought to the temperature level of the waste heat source.

  • the individual stages of the Rankine engine drive turbines via turbines.
  • the electrical energy generated by the power generators is, in addition to the electrical energy generated by the power generator of the main turbine, fed into the power grid to be supplied.
  • the arrangement for carrying out the method comprises a single-stage or multi-stage compressor, a liquefaction expansion turbine, through which a second mass flow of air exiting from the last stage of the compressor is passed; at least one countercurrent heat exchanger, which serves to exchange heat between the second mass flow emerging from the liquefaction expansion turbine and the first mass flow, an expansion valve, via which the first mass flow is isenthalp relaxed to a condensing pressure, a phase separator, in which the liquefied air from the gaseous fraction ( Cold steam), a thermally insulated storage tank for storing the liquefied air, a regasification unit adapted to increase the pressure in liquid air taken out of the storage tank and bring the temperature of the air to at least ambient temperature, and Turbine, which can be driven by means of the compressed air generated in the regasification unit.

  • the second mass flow is not liquefied, but by means of the liquefaction-expansion turbine 4 polytropically relaxed from point C to point I. During the relaxation, the second mass flow performs mechanical work which, since the waves of the liquefaction expansion turbine 4 and the compressor 1 are mechanically coupled to each other by means of a transmission (not shown), is fed to the compression process.
