A thermochemical energy storage system. The system includes a membrane-based thermochemical reactor having a solution channel having an absorbent-containing solution flowing therethrough and a refrigerant channel having a refrigerant flowing therethrough along with first and second fluid channels. A porous membrane is positioned between the refrigerant channel and the solution channel; the porous membrane permits flow of vapor molecules therethrough while restricting flow of absorbent molecules.

A low-temperature heat utilization assembly may be configured to decouple low-temperature heat from process gas at temperatures below 200? C. and to provide the process gas at a lowered intermediate temperature or at a still further lowered final temperature for at least one subsequent process. In the low-temperature heat utilization assembly the process gas may be fed to a first unit, by means of which the temperature may be lowered to the intermediate temperature. The process gas may in some cases be provided to a heat exchanger stage for further lowering to the final temperature. The first unit is an ORC unit for energy transformation of the heat energy into electrical energy and may be coupled to an electrical consumer unit. The ORC unit may be configured for energy feedback of electrical energy within the low-temperature heat utilization assembly or to a process upstream of the ORC unit.
