US 2014/0109563 A1 · METHOD AND APPARATUS FOR STORING ENERGY USING A COMBINED HEAT AND PRESSURE STORAGE DEVICE

Abstract

A method for storing energy using a combined heat and pressure storage device, includes mixing a gaseous first component and a liquid second component in an initial first step at a first pressure/temperature point to form a working medium. The working medium is compressed in a following step in such a way that the working medium has a second pressure/temperature point, at which the second component is at least partially gaseous. The compressed working medium is led into the combined heat and pressure storage device and stored there. In order to recover the energy, the working medium is expanded, whereupon the second component is at least partially liquefied. An apparatus for implementing the method is also provided.

Dependent claims

A method for storing energy using a combined heat and pressure storage device, the method comprising the following steps:

mixing a gaseous first component and a liquid second component at a first pressure/temperature point to form a working medium;
compressing the working medium to provide the working medium with a second pressure/temperature point, at which the second component is at least partially gaseous;
leading the compressed working medium into and storing the compressed working medium in the combined heat and pressure storage device;
and
expanding the working medium to at least partially liquefy the second component, for recovery of the energy.
