Title:
BULK BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/109987
Kind Code:
A1
Abstract:
The invention relates to a bulk battery for a reversible conversion of electrical energy into a combination of potential and kinetic energy of bulk material, comprising a support structure (1) comprising at least one upper hopper (3) for storing the bulk material, positioned above at least one lower hopper (2) for storing the bulk material. Each lower hopper (2) has a lower discharge cap (6) at its lower part and each upper hopper (3) has an upper discharge cap (7) at its lower part. In the direction of circulation of the bulk material, at least one conveying device (5), which is connected to a power source and suitable for conveying the bulk material from the lower hopper (2) to the upper hopper (3) and for converting electrical energy into a combination of potential and kinetic energy of the bulk material, is arranged between at least one lower hopper (2) and at least one upper hopper (3). Further, in the direction of circulation of the bulk material, at least one generator (4, 10, 11, 12, 13), which is connected to a power grid or a battery and suitable for converting the combination of potential and kinetic energy of the bulk material into electrical energy, is arranged between at least one upper hopper (3) and at least one lower hopper (2). The lower discharge cap (6), the upper discharge cap (7), the conveying device (5) and the generator (4, 10, 11, 12, 13) are connected to a control unit (14). The invention further relates to a method of converting electrical energy into a combination of potential and kinetic energy of bulk material, a method of converting a combination of potential and kinetic energy of bulk material into electrical energy, a method for preheating and/or drying material to be torrefied, a method for heating an external torrefaction reactor (17), use of the bulk battery for torrefying bulk material, and a corresponding computer program [product], a computer-readable storage medium, and a data carrier signal.
