example 1

[0119] A) Equipment

[0120] use figure 2 device shown in. The lower steel drum (1 ) with inner liner (2) has a nominal capacity of 200 liters and dimensions D=580mm and H=860mm. The sodium reservoir (4) arranged above the lower steel drum has dimensions D=580mm and H=400mm. From β″-Al 2 o 3 121 ceramic tubes fabricated and closed at the bottom are immersed in the lower steel drum (1) (2). The ceramic tube has dimensions Da=24mm, Di=20mm, L=820mm.

[0121] Sodium, 83 liters in total, in tube and sodium reservoir. Sulfur with a net volume of 145 liters flows in the lower drum and around the tubes. Each ceramic tube has a negative power inlet lead (12) located inside. These power inlet leads are protected against short circuits by fuses and attached at the top to a common collector rail (14). The positive power inlet lead (15) is arranged between the ceramic tubes and contacts the graphite non-woven fabric fixed around the ceramic tubes. Each ceramic tube with two redo...

example 2

[0129] A) Equipment

[0130] The 43 drum units described in Example 1 were placed in a 40' container. The drum units are electrically connected in series by aluminum rails. In this way, the open circuit voltage rises to 89.4 volts. A 4-quadrant thyristor rectifier DC-AC converter (10000A, 120 Volts) is used which enables controlled charge-discharge and charge of the drum unit. The electrical connections are made via aluminum rails.

[0131] B) prepare

[0132] All 43 drum elements were heated to 290°C before being charged with liquid sodium and liquid sulfur. The temperature is maintained within ±10K by adjusting the heat transfer medium circuit in the heat exchange tube (16) to a suitable temperature.

[0133] C) Charging / discharging

[0134] In automatic operation, the elementary assembly was subjected to 1000 charge / discharge cycles. In each case a discharge of more than 10 hours and a subsequent charge of more than 10 hours were carried out. The discharge power is ...

Abstract

The apparatus for storing electrical energy, comprises material A an alkali metal and material S sulfur, and two outer containers containing containers BA and BS joined by a solid electrolyte E. The materials A and S are contained separately from one another in a respective container BA and BS. The containers are arranged one above the other. The containers BA and BS are joined by the solid electrolyte E, which is permeable to cations. The containers BA and BS are contained in an outer container. The containers BA and BS are arranged one above the other as pair of barrels. The apparatus for storing electrical energy by materials A and S that form a redox couple, comprises the materials A and S, and two outer containers containing containers BA and BS joined by a solid electrolyte E. The materials A and S are contained separately from one another in a respective container BA and BS. The containers are arranged one above the other. The containers BA and BS are joined by the solid electrolyte E, which is permeable to cations. The containers BA and BS are contained in an outer container. The containers BA and BS are arranged one above the other as pair of barrels. The materials form a redox couple. The alkali metal such as sodium is present as melt, and ceramic tubes are held in an inner side formed from the electrolyte E. Rooms over standpipe communicate with the overlying common alkali metal such as sodium reservoir. The electrolyte E consists of a ceramic or cation-conducting glass. Two barrels are adjusted in a transport container, where an electrical pole is connected in series connection. A steel plate barrel (3) is a lower inner barrel, and comprises an interior trim made of an aluminum magnesium alloy. An independent claim is included for a method for storing and for transporting electrical energy below use of an electrochemical reactor.

Description

technical field [0001] The present invention relates to an improved industrial plant for large-scale storage of energy and a method for storing and transmitting electrical energy through such a plant. Background technique [0002] In the case of fossil fuel burning power stations, the generation of electricity is accompanied by CO 2 emissions and thus have a significant impact on the greenhouse effect. The generation of energy based on renewable energy carriers, eg wind, solar, geothermal or hydropower, avoids this disadvantage. However, currently these renewable energy carriers are not available whenever required depending on the consumption situation. Additionally, the energy generating location may be different from the energy consuming location. In order to compensate for this inherent shortcoming in the system, storage, buffering and possibly transmission of the generated energy is necessary. [0003] Energy from sources such as wind turbines, solar panels cannot be...
