Description

[0001] The invention relates to a universal energy cell storage system based on the premises of the VDE / ETG study "The Cellular Approach." A mix of known features is combined with an M1 energy cell storage system, creating a synergistic effect on energy generation and consumption at the level of municipalities, cities, districts, and companies, in order to balance these locally in the future.

[0002] The universal energy cell storage system M 1 is based on a pumped storage principle that has two storage tanks, as underground storage M 3 and elevated storage M 4, which are connected to each other via riser and fall pipes M10, and one or more outflow collectors M9, to the underground storage system M3, as well as reversibly to the individual energy cell reactors M22, which are driven by feedwater turbine pumps M21, via one or more pumps per water turbine, with the support of the geodetic height of the operating fluid M8, from the elevated storage system M4. The operating fluid M8, consisting of pure water with possible chemical additives, is designed for a one-time filling of the pumped storage system M20, since it renews itself through the open access of atmospheric oxygen to the elevated tank M4, or through the constant circulation of the operating fluid M8, when one or more energy cell reactors M22 are in operation.

[0003] The nationwide possible installation of the universal energy cell storage system M 1 makes it independent of natural fir waters and thus saves valuable water resources over its entire service life.

[0004] The enormous water supply in the type of operating fluid M8 requires an optimized, compact design, depending on the full volume of the elevated storage tank M4, on the one hand, and the construction height in relation to the geodetic height, on the other. The geodetic height must ultimately be adapted to the building regulations. The interior installation area should also be optimally designed to synergistically connect all M23 power centers. All in all, this requirement can be represented by a cross-shaped building over 0 meters. The foundation with the underground storage tank below will take on a rectangular or square shape. Other designs arise from the variable power sizes.

[0005] Frequency-controlled turbine pumps M 14, which are supplied with electricity from the grid or by isolated power M 18 from the universal energy cell storage M 1, supply the elevated storage M 4 from the underground storage M 3. This occurs not only internally via the control systems M 15, but also via communication systems that synergistically interconnect and manage all energy cell storage units in a cellular approach, thus enabling sustainable development of the energy supply.

[0006] Directly above the underground storage tank M 3 , there are one or more energy cell reactors M 22, all-encompassing, within the universal energy cell storage tank M1, which are driven hydraulically contactless by the operating fluid M 8 via frequency-controlled turbine pumps M 16, from the public grid or from the isolated power grid M18, of the universal energy cell storage tank M1, supported by the hydrostatic pressure with the operating fluid M 8, from the elevated storage tank M 4. This is a technology that has been used for decades in boiler construction, on the Benson boilers, is fed hydraulically contactless into the economizer at high pressure and operates the water circulation in the steam boiler.The operating fluid M 8, after flowing through the energy cell reactors M 22, flows as directly as possible into the underground storage facility M 3. The grid generator M 19, which is coupled to each of the energy cell reactors M 22, generates a frequency-controlled current according to the specifications of the higher-level communication systems and feeds this current into the grid, primarily into the distribution grids and not directly into the transmission grids. Because the energy cell storage facility M 1 is equipped with a large number of energy cell reactors M 22, which form their own power centers M 23, it is possible to branch off a so-called island current M 18 from the grid generators M 19 for internal power plants M 17, but also individual energy cell reactors M 22, which are supplied by the universal energy cell storage facility M 1 via the operating fluid M 8, thus creating a synergy dependency.Here, too, in addition to the internal control systems M 15, the higher-level communication systems are also synergistically interconnected.

[0007] Further dependent systems are included in the energy cell storage system M 1, as feature combination M 1, and are technically explained and described in the sense of the first introduction to the description above. a) that the entire operating material M 8, in terms of quantity, fits in the underground storage M 3 or high storage M 4, and is transported between them in constant readiness. b) that the entire operating fluid M 8, constantly and advantageously, comes into contact with the oxygen in the air through the pump circulation and thereby assumes the outside temperature of the ambient air, to the advantage of certain individual features, such as the self-cleaning of the operating fluid M 8. c) that with the help of b) a cold water heat source M 7 is created, which can be used for cold water ring mains M 13, to increase the efficiency of the supply of the annual performance factor of heat pumps M 11 in houses and public institutions, municipalities and the like. This shows the synergistic effect between the energy storage cell M 1 and the large number of heat pumps M 11, for which a flow temperature of approx. 15 degrees on average over the year brings about an enormous increase in efficiency and thus also greatly increases the efficiency of the energy storage cell M 1 through better utilisation of the circulating temperature of the operating medium M8. d) a photovoltaic system M 2, on the roof and on the side walls of the energy storage cell M 1, contributes to maintaining the circulating water temperature of the operating fluid M 8 at an average cold water temperature M 7, even in winter, by means of a controllable immersion heater system M 5, in the underground storage tank M 3, as well as in the elevated storage tank M4, depending on the filling level in the storage tanks M3 and M4. e) the installed heat pumps M 6, in the system of the energy storage cell M 1, take over a district heating function by using the circulating water temperature of the operating medium M 8 and pumping this average cold water temperature M 7 up to an average district heating temperature M 12 and keeping it ready in one or more heat exchangers M 14, and feeding this water with a district heating temperature M 25 into the district heating network of a municipality or the like via a ring main, as usual is returned to the heat exchanger M 14 for further processing. f) That in accordance with universal requirements, the universal energy cell storage M1, due to its size of 3,400,000 kWh capacity, over 17 operating hours, belongs to the large storage power plants and should be able to help restore the supply to the public grid as quickly as possible in the event of a power failure (blackout). To do this, the energy cell M1 must have a battery block M27 with a capacity of around 40%, the size of the drive power of an energy cell reactor M22. The remaining 60% is provided by the high-bay storage M4. It is then possible to successively start up all other installed energy cell reactors M22, so that the universal energy cell storage M1 can start up its electricity production in island operation to supply its connected heat pumps M6 and M11, its turbine pumps M14 and M16 and other systems, all of which can also be supplied via the island power grid M18.

[0008] The energy cell storage system can also operate completely autonomously in an emergency, with two to three M22 energy cell reactors available for start-up power instead of the green electricity supplied from the public grid. This allows full operation to be carried out autonomously. This makes the system, as a universal energy cell storage system, autonomous and capable of black start.

[0009] Of course, it is also important that such a giant building, close to the city, is wooded with forests that “climb” up the facades and help to make the globally rising summer temperatures in a city more bearable.

[0010] Another idea is to include an H2 hydrogen production plant, produced using electrolysis. This could power a gas turbine (operational trials are underway), which could temporarily replace the output of the universal energy cell storage system in the event of dark days or blackouts. A material storage system (metal hydrides) is suitable for this purpose, as a seasonal storage system. This would completely protect a city, municipality, or the like from power outages and would no longer have to rely on fossil alternative energy. Another advantage of the energy cell storage system is that, thanks to its high efficiency, it can provide relatively inexpensive green electricity for the production of H2 hydrogen.
