[0001] 1 STORAGE OF ELECTRICITY USING AN ELECTROLYSABLE METAL AS A VECTOR 1. TECHNICAL FIELD AND PRIOR ART The storage of electrical energy is one of the main obstacles to the implementation of intermittent energies produced by wind turbines, solar thermal, or photovoltaic light. . The energy storage methods currently used, in the absence of knowing how to store the electricity directly, are based on compressed air, hydrogen, hydraulic potential energy, flywheel etc. The quantities of energy In the case of the use of a carrier gas, this gas must be strongly compressed and stored under pressure, which in the case of hydrogen poses some serious safety problems. The use of hydrogen as an energy vector is developing in Germany around a so-called "power to gas" concept which consists in storing the electrical energy produced and not consumed in the form of hydrogen electrolysis under pressure, and injecting it on demand into the natural gas distribution networks so as to boost it. Another way to meet the energy demand is to burn the hydrogen stored in a high temperature steam turbine or to fuel a fuel cell. An alternative to the storage of hydrogen is the storage of zinc produced by electrolysis of zinc sulphate which can restore hydrogen under pressure by acid attack in a suitable reactor. This process of hydrogen generation was used during the First World War to inflate the observation balloons. Zinc is a particularly interesting material for the development of electrochemical storage solutions: its metallurgy is well known, and it is produced via an industrial mass process: electrolysis in sulfuric medium. Zinc is both a very abundant element (availability 100 times greater than lithium) and whose physicochemical properties are well known. It has the advantage of having a high energy content (> 1 kWh / kg zinc) while still being electrolyzable in an aqueous medium. This is what sets it apart from other metals with a high energy density (magnesium, aluminum), which themselves can only be electrolysed in molten salts medium, zinc being the last most reductive material that can be electrolyzed. in an aqueous medium. This is particularly related to the fact that hydrogen has an electrode overvoltage greater than that of zinc deposit. As a result, zinc is at the heart of electrochemical applications: its primary manufacture is by electrolysis, but also it is recycled by electro-refining and it is deposited as protection by electroplating. It is also historically the most used material as anode in batteries. Other metals such as iron or manganese could be used in this concept although being less energetic than zinc. 2. PRIOR ART Patent WO 2011/015723 describes a high-capacity electricity and hydrogen cogeneration device that can be operated with a single cell comprising two electrodes, for example titanium nitride and copper and alternatively allowing electrolysing an electrolysable metal (the latter may be zinc), then to restore hydrogen and electricity by cell dissolution effect. The device described can also work with differentiated cells and electrodes to optimize the operating parameters. The described electrochemical storage system operates for example with an electrolyte composed mainly of sulphate and sulfuric acid and with the following electrochemical mechanisms: at the charge (electrical storage): the metal is deposited on the negative and the oxygen at the positive-discharge (electric storage): the metal is put back in solution to the negative by generating sulfate of degree 2 and water and hydrogen is released in the positive. French Patent No. 3009654 describes a massive electricity storage system which uses an electrolysable metal as a vector in which this metal is deposited on a mobile structure in the pool and then put back into solution in attack reactors in which the hydrogen is produced under pressure all transfers being fully robotic. The object of the invention is a device for storing electrical energy in the form, for example, of zinc and of acid sulphate solution, which restores hydrogen under pressure on demand in a single reactor.

FIG. 5/5 gives a section of the closure of the capacity in a 2nd embodiment. DETAILED DESCRIPTION OF AN EMBODIMENT In a preferred embodiment of the invention, the zinc is deposited during the period electricity must be stored, and attacked when we want to produce hydrogen in the same equipment. This equipment consists of a horizontal high pressure tank Rep 200 crossed by a hollow shaft Rep 305.
[0002] This tank has an autoclave Rep 214 removable closure consisting of a lid with a conical bearing, a conical segment Rep 216, a segmented segmented rod Rep 217. Pressure screws implanted in ears welded on the cover allows to closely-tighten the conical seal between the inner wall of the capacity and the conical bearing surface of the lid Rep 215.
[0003] On this through shaft are fixed discs of dielectric composite material Rep 402. Rep. 406 spacers allow, according to their nature, spacing them, isolating them from one another or bypassing them on the central bar Rep 304. At each of its ends the shaft Rep 305 is equipped with a system rotating seal 5 Rep 204 and a slip-on manifold Rep 205. The sealing system consists of a Rep 300 sealable metal o-ring with a lip seal Rep 301. Rep 303 is used to purge the joint. A gear motor Rep 206 is mounted on one end of the shaft Rep 307 and allows it to make a rotation of 1/2 turn.
[0004] Discs of composite material Rep 401 are interposed between the mobile discs Rep 402 with a pitch of about 10 mm. These discs are centered by the fixed bars Rep 208 spaced by Rep spacers 407 and form a one-piece assembly with the support of the bars Rep 309.The mobile discs Rep 402 are guided at their periphery by a plurality of rollers Rep 405 supported by the discs Rep 401 This assembly 15 is recentered in the capacity by the bosses Rep 308. On each movable disk are fixed on both faces vis-à-vis two sheets of stainless steel or titanium in the form of a half-moon Rep 403 serving cathode and receive zinc deposition Fe or Mn. On each of the fixed discs Rep 401 are fixed on both faces facing each other four sheets in the form of a half-moon. On the lower part of these fixed disks these sheets are made of nickel made of copper, of carbon fabric or of stainless steel: they play the role of counter electrode during the acid attack of zinc. On the top: they are made of lead or titanium nitride, and play the role of anode during the deposition phase of zinc.
[0005] Depending on the type of material of the spacers Rep 407 and Rep 406, the fixed and mobile electrodes may be connected in a "press filter type" structure (the power supply is connected to the fixed end electrodes) or be paralleled by via the Rep 208 fixed bars and the Rep 304 rotary bar. A Rep205 rotary pad connector makes it possible to electrically connect the Rep 30 304 bar to the continuous electrical supply Rep 600, itself connected to a 10KV network. Rep 601 The Rep200 capacity is connected to a high pressure separator tank Rep 201 via a couple of valves Rep210. At the outlet of the balloon Rep 201 is disposed, after an isolation valve Rep 227, a hydrogen purification system Rep 500 and a weir Rep 501. The capacitor Rep 200 is connected to a circuit on which are arranged in series. : a high pressure motor valve, a low pressure separation tank, a regulation valve Rep209, a circulation pump Rep 224, a low pressure tank Rep 222, a second high pressure motor valve. A weir valve Rep 213 isolates the ball Rep 202. A ball containing neutral gas Rep 220 can inerter the capacity Rep 200 and balloons Rep 201 and 202.
[0006] A lift pump Rep 212 transfers electrolyte from the reservoir Rep 222 to the capacity Rep 200. METHOD 15 STORAGE OF ENERGY To deposit the zinc during periods of overproduction of the electrical network: The valves Rep 210 are closed to isolate the ball Rep 201 The electrodes Rep 403 of the mobile disks Rep 401 are placed in the high position: high above the horizontal diametral plane of the capacitance Rep200, opposite the lead electrodes Rep 404 of the fixed disks Rep 400. The capacitor Rep 200 and the Ball Rep 202 is completely filled by starting the pump Rep 224. The inter-electrode spaces are scanned from top to bottom by the electrolyte flow of the pump Rep 224.
[0007] The electrodes are then polarized by the feed Rep 600. The zinc is deposited on the mobile electrodes Rep 403 and the oxygen which is released concentrates in the degassing drum Rep 202. When the pressure therein is sufficient the weir opens by regulating the pressure in the balloon Rep 202 to a few bars. The level in the flask is regulated by the valve Rep 212 and the pump Rep 223.
[0008] 302 95 36 6 DESTOCKING HYDROGEN The production of high pressure hydrogen is carried out according to the following procedure: The power supply of the electrodes is cut off; the oxygen skirt of the balloon Rep 202 is purged by the complete electrolyte filling to the weir Rep 213. The electrolyte level in the balloon Rep 200 is reduced to a few cm below its diametral plane by injecting neutral gas via the valve Rep 226. The motorized valves Rep 203 are closed, the valves Rep 210 are open, the valve 10 Rep 227 and closed. The purification is in hydrogen pressure until weir Rep 501 closed the inflatable O-ring Rep 302 is supported by a neutral gas pressure. The shaft Rep 305 is progressively half a turn to plunge the mobile electrodes in the electrolyte thus causing the dissolution of zinc and the evolution of hydrogen.
[0009] The electro-chemical battery effect produced by the dissolution makes it possible to recover low-voltage electrical current between the fixed and moving electrodes in the low position. This energy is converted by a BARLOW wheel-running unit and a Rep 602 inverter which allows low-voltage alternating current to be injected into a user network Rep 603. INDUSTRIAL APPLICATIONS 25 This high-capacity electrical storage can be used in photovoltaic or thermal solar power plants to ensure nighttime production and wind turbine fields to smooth their production. 9.ABREGE: Energy storage based on electrolessable sulphate-based electrical energy, making it possible to produce pressurized hydrogen without the need for a compressor within the same reactor. 10.
