Description

[0001] The invention relates to a device for producing hydrogen.

[0002] DE 20 2023 105 065 U1 discloses a system for producing hydrogen from water using a high-temperature electrolyzer. Using solar energy, liquid water is evaporated and then fed to the high-temperature electrolyzer.

[0003] The invention is based on the object of designing a device for producing hydrogen that is particularly ecological and practical.

[0004] This object is achieved with a device for producing hydrogen which has at least the following features: a) a support device, b) several photovoltaic modules attached to the support device in a predetermined geometric arrangement, c) an energy storage device for storing the electrical energy generated by the photovoltaic modules, d) a collecting device for collecting rainwater and a water storage tank connected to the collecting device in which collected rainwater can be stored, e) an electrolysis device to which water from the water reservoir and electrical energy from the energy storage device can be supplied, wherein the electrolysis device is designed to split the supplied water into gaseous hydrogen and oxygen by means of the electrical energy and to provide the hydrogen and oxygen separately from one another at respective output connections.

[0005] Such a device can be designed similarly to a tree and can therefore be set up in many locations without great effort. The support device serves to hold and support the photovoltaic modules. The photovoltaic modules can be attached to the support device at a fixed position and in a fixed spatial orientation. As explained below, the photovoltaic modules can also be arranged adjustably on the support device. The photovoltaic modules can, for example, be arranged in such a way that they collect rainwater and direct it to the collection device and / or the water storage tank. The water storage tank can, for example, be located underground.

[0006] The collection device is used to collect rainwater. The collected rainwater can then be fed to the water storage tank, for example, via a pipe. The collection device can be installed independently of the photovoltaic modules, e.g., at a distance from the photovoltaic modules. In this case, only the rainwater collected by the collection device is fed to the water storage tank.

[0007] According to an advantageous embodiment of the invention, the collection device is spatially coupled to the photovoltaic modules so that rainwater collected by the photovoltaic modules can be directed into the collection device and thus into the water storage tank. This enables a particularly space-saving, compact design of the device. The relatively large photovoltaic modules already provide a relatively large collection area for rainwater. This relatively large collection area is advantageously used to collect collected rainwater and store it in the water storage tank so that the precipitation can be used effectively even in periods of little rain. The collection device can, for example, be arranged in the immediate vicinity of the support device and / or underneath the photovoltaic modules so that collected rainwater flows from the photovoltaic modules to the collection device under the influence of gravity.

[0008] If the collecting device is not spatially coupled to the photovoltaic modules in order to collect the rainwater collected by the photovoltaic modules, it can be arranged adjacent to the photovoltaic modules, for example, and offer a correspondingly large collecting area. If the collecting device is designed such that it is spatially coupled to the photovoltaic modules, the collecting device can be made significantly smaller than if it were arranged externally. For example, the collecting device can then be designed as a gutter or funnel. In an advantageous embodiment, part of the collecting device can be spatially coupled to the photovoltaic modules in order to collect the rainwater collected by the photovoltaic modules, and another part of the collecting device can be arranged at a distance from the photovoltaic modules in order to collect rainwater independently of the photovoltaic modules and feed it to the water storage tank.

[0009] The electrolysis device can advantageously be operated directly with the resources provided by the device according to the invention, namely the collected rainwater from the water reservoir and the electrical energy generated by the photovoltaic modules and stored in the energy storage device. Therefore, in one advantageous embodiment, it is possible for the device according to the invention to be designed as a self-sufficient system for producing hydrogen. The system can then be self-sufficient, at least with regard to the required electrical energy and water, and is thus not dependent on external sources.

[0010] However, it is also possible, for example, to bridge dry seasons or periods of low solar radiation, to supply part of the required electrical energy and / or part of the required water from external sources. In this case, the device according to the invention can, for example, have a mains connection for connection to the power grid and / or a water connection for connection to the water network. The device according to the invention can then operate at least largely autonomously.

[0011] For example, the photovoltaic modules can be permanently arranged in a funnel shape, allowing them to collect rainwater particularly efficiently and direct it to the collection device. In this case, the adjustment device explained below is not absolutely necessary.

[0012] According to an advantageous embodiment of the invention, the support device has an adjustment device with which one, several or all of the photovoltaic modules can be adjusted with regard to their position in at least one spatial direction. This has the advantage that further advantageous functions can be implemented with the device according to the invention, with which the efficiency and effectiveness of the device can be significantly improved. For example, the photovoltaic modules can be adjusted in at least two spatial directions by means of the adjustment device, in particular out of the xy plane (horizontal plane). The adjustment device allows the photovoltaic modules to be individually adjustable. It is also possible for the adjustment device to individually adjust the photovoltaic modules as a whole unit or in several individual groups.To carry out the adjustment movements, the adjustment device can have one or more servo motors, for example in the form of linear drives, for example with stepper motors.

[0013] In a further advantageous embodiment, the photovoltaic modules cannot be individually adjusted by the adjustment device, but can always be arranged relative to one another in a fixed spatial configuration, e.g., in the previously explained funnel shape. Then, for example, only the entire fixed arrangement of photovoltaic modules in the funnel arrangement can be adjusted in terms of their position in at least one spatial direction by the adjustment device, e.g., in order to optimally align the photovoltaic modules arranged in the funnel shape with respect to the position of the sun.

[0014] According to an advantageous embodiment of the invention, the adjustment device is configured to optimally align the photovoltaic modules with respect to the position of the sun. This allows the electrical energy yield to be optimized. The adjustment device can, in particular, be configured to optimally align the photovoltaic modules with the direction of solar radiation depending on the time of day and / or the calendar date.

[0015] According to an advantageous embodiment of the invention, the adjustment device is configured to optimally align the photovoltaic modules with respect to the position of the sun only during a rain-free period. This has the advantage that a different adjustment characteristic of the photovoltaic modules can be implemented during a non-rain-free period. Depending on whether a rain-free period or a non-rain-free period (rainy period) is present, the adjustment device can implement a respective adapted adjustment characteristic of the photovoltaic modules. For example, during a rainy period, the photovoltaic modules can be adjusted in order to optimally direct the rainwater collected by the photovoltaic modules to the collection device.

[0016] The adjustment device can, for example, determine whether a rain-free period exists or not according to a scheme explained below.

[0017] According to an advantageous embodiment of the invention, the adjusting device is configured to adjust the photovoltaic modules into a funnel shape during a rainy period, wherein the funnel shape gathers the rain falling onto the photovoltaic modules in a funnel-like manner and guides it to a water intake opening of the collection device. This optimizes the utilization rate of the rainwater as best as possible. For example, during other time phases, i.e., when there is no rainy period, the photovoltaic modules can be adjusted by means of the adjusting device into a flat position in which the photovoltaic modules are arranged essentially in one plane or at least parallel to one another.

[0018] According to an advantageous embodiment of the invention, the adjusting device has a controller that is configured to control the adjustment of the photovoltaic modules, wherein the controller is configured to detect whether or not a rainy period is present at the location of the device. Such a controller can, for example, be designed as an electronic controller, e.g. a controller controlled by a computer program. The controller can, for example, have a rain sensor to record the actual amount of rain falling per unit of time at the installation location of the device. Alternatively or additionally, the controller can, for example, be connected to an external information source, e.g. via the Internet, in order to retrieve and evaluate weather data and to deduce from this whether or not a rainy period is present. Depending on the recorded data on the amount of rain falling at the location of the device, the controller can, for example,By comparing the minimum rainfall value with a minimum rainfall value, it is determined whether a rain-free period or a rainy period is required for the adjustment of the photovoltaic modules. For example, the minimum rainfall value can be set so that, in light drizzle, the photovoltaic modules are not yet adjusted to a funnel shape, but continue to adjust the photovoltaic modules based on the position of the sun. Only when the rain starts to fall heavily can the photovoltaic modules be adjusted to the funnel shape.

[0019] The control system can be configured to adjust the photovoltaic modules into the funnel shape by means of the adjustment device during a rainy period and to adjust them into the flat position during a rain-free period.

[0020] The general geometry of the support structure and the arrangement of the photovoltaic modules on the support structure can be implemented in a variety of ways. In a first advantageous variant, the photovoltaic modules can be arranged in at least two rows to form an elongated chain with at least two rows. If the photovoltaic modules are then adjusted to a funnel shape, they take on the form of an elongated V-shaped gutter, through which the rainwater is directed into an elongated collecting device located below the V-shaped gutter arrangement, which can be designed as a comparatively narrow gutter.

[0021] According to an advantageous embodiment of the invention, the photovoltaic modules are arranged in a ring shape on the support device. For example, the photovoltaic modules can be arranged in a ring around a center of the support device. This is a particularly advantageous arrangement of the photovoltaic modules for the compact design of the device and for the efficient adjustment of the photovoltaic modules into a round funnel shape, in this case. The photovoltaic modules can be arranged around a center of the support device, for example, like the petals of a plant.

[0022] According to an advantageous embodiment of the invention, the photovoltaic modules are arranged around a center of the support device. The photovoltaic modules can be attached directly to the support device. The photovoltaic modules can also be attached to the support device via a respective holder. According to an advantageous embodiment, one, several or all of the holders can have an outer contour that is wedge-shaped and oriented towards the center. The wedge-shaped contour towards the center makes it possible to form a round funnel particularly efficiently during a rainy period, in which the holders and photovoltaic modules are arranged relatively close together even in the center, thus enabling a particularly high degree of rainwater collection.

[0023] A further advantage of the previously described bracket design is that commercially available rectangular photovoltaic modules can be used. The wedge-shaped design is then realized via the brackets. It is also conceivable for one, several, or all photovoltaic modules to have an outer contour that is wedge-shaped and aligned toward the center. Then, the particularly efficient collection functionality described above can be realized directly by the photovoltaic modules. The brackets and / or photovoltaic modules can, for example, have a triangular outer contour or a pentagonal outer contour.

[0024] According to an advantageous embodiment of the invention, the device has at least one first gas storage container, to which the gaseous hydrogen obtained by the device is supplied. This has the advantage that the device can also operate autonomously with regard to hydrogen storage, at least during certain periods of time. Gaseous hydrogen can then be withdrawn from the first gas storage container as needed, e.g., to refuel a hydrogen-powered vehicle.

[0025] It is also possible for the device to have a reformer. The device can then be configured to convert the resulting gaseous hydrogen into methanol using the reformer. The liquid methanol can then be temporarily stored in a liquid tank.

[0026] The gaseous oxygen produced during electrolysis can either be released directly into the atmosphere. Alternatively, the gaseous oxygen can be stored. In this case, it is advantageous if the device has at least a second gas storage container to which the gaseous oxygen produced by the device is fed. The gaseous oxygen can then be used for other applications as needed.

[0027] According to an advantageous embodiment of the invention, the device has at least one support leg to which the adjustable carrier device is fastened, wherein at least the adjustable carrier device is positioned on the ground via the at least one support leg. The support leg can be designed as a comparatively slender leg compared to the planar extent of the photovoltaic modules. In this way, little space is required on the ground for the installation of the device according to the invention. This has the advantage that the device according to the invention can also be installed in areas that are also used for other purposes, e.g. agricultural land or parking spaces for vehicles. The device according to the invention can then be designed similarly to a tree with the photovoltaic modules or the carrier device held on the support leg.

[0028] In an advantageous embodiment, the rainwater collection device can be arranged below the photovoltaic modules at a central location on the support leg. The support leg can have an internal hollow channel to direct the rainwater collected by the collection device to the water storage tank.

[0029] For the purposes of the present invention, the indefinite term "a" is not to be understood as a numerical term. Therefore, if, for example, a component is mentioned, this is to be interpreted as "at least one component." Angles expressed in degrees refer to a circle of 360 degrees (360°).

[0030] The invention will be explained in more detail below using exemplary embodiments and drawings. Fig. 1 a device for producing hydrogen in a schematic representation, Fig. 2 a concrete constructive embodiment of a device according to the invention in perspective view, Fig. 3 a support leg of the device according to Fig. 2, Fig. 4 a support device with photovoltaic modules attached to it, Fig. 5 the order pursuant to Fig. 4 in a different perspective view, Fig. 6 the order pursuant to Fig. 5 when adjusting the photovoltaic modules into a funnel shape.

[0031] The Fig. The device 1 shown in Figure 1 has a support device 2 to which several photovoltaic modules 3 arranged in a predetermined geometric arrangement are attached. Furthermore, the device 1 has an energy storage device 4 in which electrical energy generated by the photovoltaic modules 3 can be stored. The device 1 also has a collecting device 5 for collecting rainwater, e.g., rainwater collected by the photovoltaic modules 3. The collecting device 5 is connected via a line 12 to a water reservoir 6 in which collected rainwater 7 can be stored.

[0032] The device 1 further has an electrolysis device 8, to which the water 7 from the water storage tank 6 can be fed via a line 14. In addition, electrical energy from the energy storage device 4 or directly from the photovoltaic modules 3 can be supplied to the electrolysis device 8. The electrical energy is used by the electrolysis device 8 to carry out electrolysis, in which the water 7 is split into gaseous hydrogen and gaseous oxygen. The hydrogen can be fed, for example, via a line 15 to a first gas storage tank 9, in which the hydrogen is initially stored. The gaseous hydrogen can be withdrawn from the first storage tank 9 via a withdrawal connection 16, as required. The gaseous oxygen can be supplied to a second storage tank 17 via a line 18.If required, gaseous oxygen can be withdrawn from the second gas storage container 17 via a withdrawal connection 19.

[0033] The device 1 also has an adjustment device 13, by means of which one, several or all photovoltaic modules 3 can be adjusted with regard to their position in at least one spatial direction.

[0034] It can also be seen that the device 1 has a support leg 11 that is positioned on the ground 21. At least the support device 2 with the photovoltaic modules 3 and at least parts of the adjustment device 13 are attached to the support leg 11. The collecting device 5 can also be attached to the support leg 11. The support leg 11 thus forms a central support device that can be designed similarly to the trunk of a tree.

[0035] In the Fig. 1 shows, by way of example, that the gas storage tanks 9, 17 and the water storage tank 6, as well as the electrolysis device 8, are arranged underground, i.e., below the surface of the ground 21. The remaining elements are arranged above ground. However, this distribution is not necessarily required in every case. It is also conceivable that one or both of the gas storage tanks 9, 17 and / or the water storage tank 6 and / or the electrolysis device 8 are arranged above ground.

[0036] To control the adjustment of the photovoltaic modules 3 and to carry out further control and regulation functions, the device 1 can have an electronic controller 10. By means of the controller 10, e.g. in conjunction with a rain sensor connected to it, it can be determined automatically whether a sufficient amount of rain is falling at the installation location of the device 1 to justify aligning the photovoltaic modules 3 by means of the adjustment device 13 not with the position of the sun 20, but rather moving them into a funnel shape through which as much rainwater as possible can be collected and fed to the collection device 5. If the controller 10 determines that there is no rain or too little rain, the controller 10 can adjust the photovoltaic modules 3 again by controlling the adjustment device 13 such that their orientation is optimized for absorbing sunlight.

[0037] If there is no direct sunlight, the controller 10 can be configured to adjust the orientation of the photovoltaic modules 3 to the brightest point in the sky using the adjustment device 13. For this purpose, the controller 10 can, for example, have a camera for detecting the brightest point in the sky. Alternatively, the controller 10 can iteratively detect the optimal alignment to the brightest point in the sky by repeatedly readjusting the orientation of the photovoltaic modules 3. The controller 10 can evaluate the amount of electricity generated by the photovoltaic modules 3 and adjust the photovoltaic modules 3 to achieve a maximum.

[0038] The Fig. 2 shows a device according to the invention with further details. It can be seen that the support leg 11 can be constructed in several parts, e.g., with three support leg segments 22 fastened to the base 21 in the shape of a triangle. The support leg segments 22 fork toward the support device 2. As part of the adjustment device 13, a servomotor 23, e.g., a linear motor, controllable by the controller 10 can be fastened to each forked section of a support leg segment 22. The support device 2 can have an adjustable, annular frame 24, which is fastened to the three servomotors 23 in the manner of a three-point fastening.

[0039] The Fig. 3 shows the supporting leg 11 according to Fig. 2 as a single part with the servomotors 23 attached to it. The servomotors 23 are each connected to the respective support leg segment 22 via a joint. The joint allows each servomotor 23 to pivot about an axis.

[0040] As the Fig. As illustrated in Figure 4, the photovoltaic modules 3 can be designed as conventional rectangular modules. Each photovoltaic module 3 is mounted on a bracket 25. A bracket 25, together with the photovoltaic module 3 mounted thereon, forms a solar panel. The device has several solar panels arranged in a circle.

[0041] The brackets 25 are wedge-shaped towards the center 28 of the arrangement in order to form the narrowest possible funnel in the center region for collecting rainwater. The photovoltaic modules 3 are pivotally coupled to the annular frame 24 via their respective brackets 25 at a location remote from the center 28. In the area of ​​the center 28, the brackets 25 are pivotally coupled to a central mounting element 27. The central mounting element 27 is connected to the annular frame 24 via connecting arms 29. The connecting arms 29 are connected to one another in the area of ​​the central mounting element 27 via a coupling element 26. The coupling element 26 can be adjusted linearly along the central mounting element 27, as the Fig. 5 and Fig. 6. By this adjustment, the arrangement of the photovoltaic modules 3 can be changed from a substantially flat, level arrangement, as in the Fig. 2, Fig. 4 and Fig. 5 is recognizable, in a Fig. 6 shown funnel shape can be adjusted.

[0042] The Fig. 5 and Fig. 6 each show only one half of the arrangement of the photovoltaic modules 3 and their holders 25.

[0043] The servomotors 23 can be used to track the entire arrangement of the photovoltaic modules 3 according to the position of the sun, for example by changing the Fig. 2 recognizable inclination of the photovoltaic modules 3 into a different orientation towards the sun.

[0044] The underlying idea is the integration of a funnel function of the photovoltaic modules 3 into a structure that can pivot, for example, around two axes (here x and y). The funnel function requires several large-area plates formed by solar panels. These are individually guided on the annular frame 24 along their central axis. Furthermore, they are rotatably mounted on the annular frame 24. They thus possess two degrees of freedom: translational along their central axis and rotational around the annular frame 24.

[0045] The funnel function is controlled, for example, by a servo motor that moves the central mounting element 27 in the z-axis. For this purpose, it is connected to the central mounting element 27 on one side and is supported on the other side by the flange on the ring-shaped frame 24, as shown in the Fig. 6 can be seen.

[0046] Up to this point, the system has exclusively served as a funnel. By adding servomotors, e.g., linear motors, pivoting around two axes is possible. For this purpose, three servomotors 23 are mounted at the maximum distance from each other (120°) to the ring-shaped frame 24, as shown in the Fig. 2. On the other side, the servo motors 23 are fixedly mounted. This design allows the hopper to be pivoted and precisely aligned to an object by the control system 10.

[0047] In the Fig. Figure 3 shows the structure for which the dynamic hopper was developed. The support leg 11 of the structure represents the bearing of the servo motors 23, which are arranged centrally at an angle of 120° to each other. The dynamic hopper is the main movable assembly, as shown in the Fig. 4 to 6. The annular frame 24 is the central component. The annular frame 24 is connected to the bearings by the servomotors 23. Since the servomotors 23 can be controlled individually, the annular frame 24 can be oriented in any direction.

[0048] This system makes it possible to align the photovoltaic modules 3 according to the brightest light source. On the annular frame 24 there are six brackets 25 which are arranged in a circle around the center 28. The brackets 25 support the photovoltaic modules 3 and, in their second function, together form the funnel. The brackets 25 are directly connected to a linear guide, which is connected to the counterpart by a bivalent bearing (e.g. ball head bearing) on ​​the annular frame 24. This connection means that the solar blades only have two degrees of freedom: one along their central axis and one around the annular frame 24. At the center of the assembly is the central mounting element 27, which centers and adjusts the solar blades. A further servo motor allows the central mounting element 27 to be moved vertically along the coupling element 26.The annular frame 24 and the coupling element 26 can be firmly connected as a single unit. When the central mounting element 27 reaches its lowest position, the solar panels form a funnel with a hole in the center, as shown in the figure. Fig. 6 shows. Once the central mounting element 27 has reached its uppermost position, the solar panels, and thus the photovoltaic modules 3, are in one plane, as shown in Fig. 5 shows.

[0049] The funnel-shaped design allows the rain to be collected and drained through a centrally mounted pipe. It is advantageous for this to happen if the ring-shaped frame 24 moves to a horizontal position when it rains. As soon as it stops raining, the solar panels return to a flat position, and the ring-shaped frame 24 aligns the solar panels to the brightest spot.

[0050] The device combines the two functions of tracking solar systems and the funnel function. For example, when combined with an electrolysis system, a self-sufficient, stand-alone system can be created. The three-point bearing also makes it possible to control the linear motors individually, without the need for a second motor to respond.
