Patent AT-E399939-T1: [Translated] DEVICE FOR STORING THERMAL ENERGY FOR SUBSEQUENT CONVERSION INTO ELECTRICAL ENERGY

The device has at least one heat energy and pressure storage module. Each of these has a heat input transmission device (1) and a pressure reservoir (2). These are connected to each other for exchange of fluid (30). An energy conversion device is connected to the pressure reservoir for fluid exchange, and the energy accumulated as fluid pressure in the module, is converted into a second energy. The device may have several modules connected to a distributor (40), which intermittendly connects individual modules to the energy conversion device. The device is formed by a hydraulic motor (5) and an optional generator (6) connected to it. It has a heat exchanger (35) connected to it, which is connected via a circulation pump (9) to the solar connector. The heat input transmission device is a solar collector or an IC engine.
