Abstract
The present disclosure relates to thermochemical heat storage units. The teachings thereof may be embodied in systems and methods for operating, including charging and discharging, a thermochemical heat storage unit. For example, a method for operating a thermochemical heat storage unit may include: producing a first steam and feeding it to a heat exchanger; partially condensing the steam with release of its thermal energy, in the heat exchanger; subsequently pressurizing water condensed from the steam; feeding the pressurized water to the heat exchanger; evaporating the water into a second steam; and storing at least a portion of the second steam in a steam storage unit.
Claims7
A method for operating a thermochemical heat storage unit, the method comprising:
- producing a first steam and feeding the first steam to a heat exchanger;
- at least partially condensing the first steam with an at least partial release of its thermal energy, by means of the heat exchanger;
- and
- subsequently pressurizing water condensed from the first steam;
- returning at least some of the pressurized water to the heat exchanger;
- at least partially evaporating the water into a second steam by absorbing thermal energy previously released;
- and
- storing at least a portion of the second steam in a steam storage unit.
