Definitions
- the invention relates to an offshore electrolysis plant and a method for operating an offshore electrolysis plant.
- An electrolysis system is a device that uses electricity to convert substances (electrolysis).
- electrolysis electrolysis
- electrolysis systems such as an electrolysis system for water electrolysis.
- Hydrogen is now generated from water, for example by means of proton exchange membrane (PEM) electrolysis or alkaline electrolysis.
- PEM proton exchange membrane
- the electrolysis systems use electrical energy to produce hydrogen and oxygen from the water supplied. This process takes place in an electrolysis stack composed of several electrolysis cells.
- water is introduced as the educt, with two fluid flows consisting of water and gas bubbles (O 2 or H 2 ) exiting after passing through the electrolysis cells.
- a resource can be hydrogen, in particular, which is generated by water electrolysis systems.
- so-called EE gas can be produced using hydrogen.
- renewable gas is a combustible gas that is obtained from renewable sources using electrical energy.
- Hydrogen is a particularly environmentally friendly and sustainable energy source. It has the unique feature Potential to realize energy systems, traffic and large parts of the chemical industry without CCd emissions. For this to succeed, however, the hydrogen must not come from fossil sources, but must be produced with the help of renewable energy.
- offshore electrolysis systems In offshore electrolysis systems, special attention must be paid to avoiding corrosion, because the presence of salt water can lead to significantly higher corrosion rates, which endangers longer uninterrupted operation of an electrolysis system.
- offshore electrolysis plants can be equipped with electrolysers and housed within closed housings, the containers. As a result, a certain degree of protection from external environmental influences can be achieved for the electrolyser. However, for operational reasons, the electrolyser has to be cooled in order to dissipate the waste heat from the electrolysis process to the environment.
- Efficient cooling and use of waste heat from an onshore electrolysis plant is described, for example, in EP 2623 640 A1 described.
- the efficiency of an electrolyser for generating hydrogen and oxygen by separating water is increased by storing waste heat generated in the electrolyser in a heat transfer medium, feeding the heat transfer medium to a water treatment plant and using the waste heat to produce deionized water from raw water in the water treatment plant will.
- the heat transfer medium is circulated in a closed circuit between the electrolyser and the water treatment system.
- a respective heat exchanger ensures that the heat is absorbed and dissipated from the housing of the electrolysis system as well as a corresponding heat transfer and supply to the water treatment system.
- a further object is to specify a method for operating an offshore electrolysis plant.
- an offshore electrolysis system comprising an electrolyzer arranged in a container and a heat exchanger which absorbs heat and dissipates process heat from the electrolysis is designed in a closed coolant circuit from the container, wherein a coolant pump for pumping the coolant in the coolant circuit is arranged in the container.
- the object directed to a method for operating an offshore electrolysis system is solved according to the invention by a method for operating an offshore electrolysis system with an electrolyzer arranged in a container, in which medium for absorbing heat and dissipating process heat from the electrolysis from the container is guided in a closed coolant circuit, with a coolant pump arranged in the container being operated.
- the invention is based on the knowledge that the more powerful offshore wind turbines that are being installed and their growing electrical generation capacity require correspondingly more powerful electrolytic systems. It is therefore expected that the performance class of an offshore electrolysis plant and their number will increase significantly in the future. The associated increasing requirements for safe and environmentally friendly operation in the maritime environment must be taken into account. Due to the scaling efforts towards larger offshore electrolysis plants, the question of environmental compatibility is moving into the focus of the discussion. Here, an operation that is as intrusive as possible from an environmental point of view is to be guaranteed. The solution to the cooling task for operation is therefore of particular importance with simultaneous operational reliability and performance of the offshore electrolysis system.
- the offshore electrolysis plant according to the invention recognizes and overcomes here for the first time the disadvantages of conventional open cooling approaches for the cooling medium.
- a coolant pump for promoting the coolant is arranged in the offshore electrolysis plant in the coolant circuit.
- the coolant pump is designed according to the cooling capacity.
- the coolant pump is therefore housed in the container itself, approximately in the vicinity of the electrolyzer to be cooled in the offshore electrolysis plant.
- a fixed coupling is also possible here by tightly flanging the coolant pump directly to the container, for example from the outside, so that an integral housing unit of the coolant pump is then formed with the container.
- the protection and cooling concept should therefore be understood within the scope of the invention in such a way that even if the coolant pump is flanged, screwed on or otherwise directly coupled to the container, the electrolyser and the coolant pump are seen as being housed in the same container, with a housing unit is formed. This is for maintenance and revision purposes on the coolant pump particularly advantageous because, if necessary, easier access to the coolant pump from the outside is possible. As a result, the particularly sensitive devices such as in particular the electrolyser, the heat exchanger and the coolant pump are protected for offshore use and the offshore electrolysis system is made up accordingly for offshore operation in a special way.
- a heat exchanger with a correspondingly large heat exchanger surface is provided in the closed coolant circuit for the heat dissipation of the process heat absorbed by the coolant, which heat exchanger can be immersed in the sea.
- the invention thus provides for the use of seawater as a heat sink in an almost large reservoir in front of the cooling medium, with only the heat being emitted by the heat exchanger immersed in the sea with a closed cooling circuit.
- the intervention of this construction from environmental point of view is low, especially since a material decoupling of coolant and sea water is provided.
- pivoting devices and/or hoists are provided on the offshore electrolysis plant, which enable corresponding movements of the heat exchanger such as immersion or lifting.
- the generally relatively large exchange surface for the large-area heat exchanger can advantageously be dimensioned and constructively designed for the necessary cooling capacity by means of a corresponding thermal engineering design.
- the heat exchanger in particular the large-area heat exchanger, has a pipe that is designed with ribs and/or fins on the coolant-carrying pipe outer surface and/or is guided in a large number of pipe bends.
- the heat exchanger can be designed as a meandering tube and/or tube provided with fins.
- the volume flow of the coolant can be divided over several parallel pipes in order to obtain a larger heat exchange surface.
- the pipeline in particular the pipeline bundle, is made of steel, preferably a corrosion-resistant stainless steel.
- the pipeline in particular the pipeline bundle, also advantageously has an anti-corrosion layer on the outer surface.
- the large-area heat exchanger immersed in seawater can be made of steel. Similar to ships, however, measures should preferably be taken to counteract corrosion, such as cathodic corrosion protection or the use of a sacrificial anode. Simple protective coatings, on the other hand, could reduce the desired heat transfer and are therefore not recommended unless the protective coating is adapted and suitable with regard to the influence on the heat transfer to be achieved.
- fouling This contamination of heat exchangers and heat exchangers, known as "fouling", and the resulting cleaning are always a challenge for the company.
- responsible for the different deposits are water with a high salt content, high temperatures and contamination in the water - as well as the cooling capacity of a heat exchanger The harder and thicker the deposits become, the poorer the heat transfer.
- the anti-corrosion layer has titanium. It can also be made of titanium. In a preferred embodiment, it is also possible to use pipelines made of titanium overall for the large-area heat exchanger.
- Titanium shows very good corrosion resistance to seawater.
- suitable insulators to separate the materials. Otherwise there is the potential that so-called local elements form, which can cause corrosion.
- Local elements are generally small-scale corrosion elements (or contact elements) that are hardly visible to the naked eye. Local elements can form at points of contact between two different metals as a result of the effects of moisture, for example caused by aerosols, and often cause considerable corrosion there.
- the large-area heat exchanger is arranged in a frame which includes the heat exchanger and holds the heat exchanger in position by means of fastenings for the respective operating state.
- a modular structure is realized with a module comprising the heat exchanger and the frame as a structural unit and auxiliary attachments, such as connections or flange connections for the pipelines for connection to the container of the offshore electrolysis plant.
- the heat exchanger that can be immersed in the seawater is housed in the frame, which preferably has the dimensions of a standard container in the logistics industry. This makes it particularly easy to transport the heat exchanger and, if necessary, to replace it after a certain operating time, which is advantageous for maintenance and service purposes.
- the frame with the large-area heat exchanger is therefore preferably fastened in such a way that, if necessary, it can be guided out or tilted out of the seawater.
- the frame with the large-area heat exchanger can preferably be tilted out via a rotatable attachment. It is particularly useful and advantageous to construct the large-area heat exchanger immersed in the seawater in such a way that it can be "folded out” or tilted out of the water with simple means, for example with the help of a cable winch. This can preferably be done by a rotatable or rotating - Be realized / tiltable fastening device on the frame.
- the possibility of folding the large-area heat exchanger out of the seawater is a particularly advantageous design development, especially given the requirements in the offshore area for an offshore electrolysis plant.
- Alternative pipe routings for the heat exchanger are conceivable, which do not require the removal of pipe sections to fold out the heat exchanger.
- the frame can be tilted around the heat exchanger via the rotatable attachment. With a corresponding flange connection for the flow and the return, which are attached and aligned exactly on the corresponding axis of rotation, only the flange needs to be opened and fitted with dummy disks to fold it out.
- hoses or bellows systems or combinations of these line elements as a connection to the container with the electrolyser in order to allow it to be folded up or tilted out without a pipeline having to be loosened, cut open or closed.
- hoses can also be made of suitable plastic.
- the offshore electrolysis system is designed with a connection unit for feeding in electrical current from an offshore wind turbine.
- the offshore electrolysis system according to the invention is installed on an offshore platform in the sea.
- Disused oil or gas platforms such as those found in abundance in the North Sea, for example, could serve as the basis for such wind power electrolysis.
- the hydrogen produced there could then be conveniently routed to onshore power plants via the existing natural gas pipelines.
- a coolant is guided in a closed coolant circuit for absorbing heat and dissipating process heat from the electrolysis from the container, with a coolant pump arranged in the container being operated .
- a coolant pump arranged in the container is in principle also understood to mean a fixed coupling by tightly flange-mounting the coolant pump directly to the container from the outside, so that a housing unit of the coolant pump is then formed with the container.
- this should be understood to mean that even when the coolant pump is flanged on or coupled the container, the electrolyzer and the coolant pump are housed in the same container, with a housin segnac being formed.
- heat is transferred from the coolant heated by the process heat to sea water and the coolant cools as a result.
- a damaging ingress of seawater into the coolant circuit is preferably monitored.
- a corresponding sensor for detecting leaks in the coolant circuit can be applied and used.
- a measurement of the electrical conductivity is preferably carried out using a conductivity sensor, which reacts correspondingly sensitively to a salt content caused by seawater, so that an undesired intrusion of seawater is indicated and appropriate countermeasures can be taken.
- seawater as a coolant in an open coolant circuit
- Electrolysis system according to the invention with a closed coolant circuit
- Electrolysis plant according to the invention.
- FIG. 1 shows an electrolysis system 1a in which an electrolyzer, not shown in detail, for example a PEM or Al-potassium electrolyzer, is arranged in a container 2 or other housing.
- the electrolyser is designed to generate hydrogen as a product from the electrolysis of water as a starting material.
- the electrolysis system 1a has an air cooler 6 for cooling and heat dissipation of the process heat during the operation of the electrolyser.
- a coolant circuit 3 ensures the circulation of a coolant, with a medium to be cooled being passed through a heat exchanger 4 with correspondingly large heat exchange surfaces to the atmosphere.
- a coolant pump 5 delivers the coolant.
- FIG. 2 shows an offshore electrolysis plant 1b, in which an electrolyzer (not shown in detail), for example a PEM or alkali electrolyzer, is arranged in a container 2.
- the offshore electrolysis plant lb is arranged on a support structure 10, an offshore platform, which is located above sea level 11 and is anchored to the seabed.
- An electrolyzer (not shown in detail), a coolant pump 5 and a heat exchanger (4) are provided in the container 2 .
- Seawater is used as the coolant and for cooling purposes pumped to the heat exchanger 4 by means of the coolant pump 5 from the sea harnessge.
- an intake socket 12 is provided under water in the suction line leading to the heat exchanger 4, in which the coolant pump 5 is inserted. builds is.
- the coolant pump 5 As shown in FIG. 2, is to be arranged inside the container 2, if the difference in height is too great, it may even happen that the vapor pressure of the sea water has a limiting effect and cavitation occurs. In this case, even with the most powerful pumps, it would not be possible to suck in the seawater, which is very disadvantageous for efficient cooling operation. Alternatively, the pump would have to be placed closer to the water surface, where it may be more exposed to environmental influences and where access for maintenance and repairs would be more difficult.
- the return line 13 is connected downstream of the heat exchanger (4).
- the return line 13 submerges below sea level 11 and returns the heated seawater.
- an open cooling concept has been implemented in the offshore electrolysis system lb, which uses seawater as a coolant and is not only disadvantageous from an environmental point of view in the maritime sector, but also with regard to operational safety and service life, which is explained below using a few selected aspects:
- sea water is sucked in through the suction nozzle 12 , which is below sea level 11 , with the aid of the powerful coolant pump 5 and conveyed through the heat exchanger 4 .
- the electrolyzer medium to be heated is conducted (not shown in FIG. 2), so that the heat is transferred directly to the seawater as a coolant.
- the heated sea water is returned to the sea via return line 13 through an outlet port.
- This cooling concept has disadvantages. In order to avoid blockages or defects in the coolant pump 5, it must be ensured that no larger foreign bodies or even marine life are sucked in. This can be done with complex filter systems, which can clog over time and therefore regularly need to be cleaned.

- this electrolysis system 20 overcomes the disadvantages of the embodiments described in FIGS. 1 and 2 above.
- the offshore electrolysis plant 20 shows a container 2 in which an electrolyzer, not shown in detail, for example a PEM or alkaline electrolyzer, is arranged.

- the 22 includes the heat exchanger 21 and holds the heat exchanger 21 in position for the respective operating state via the fastenings 24a, 24b.
- the operating position of the large-area heat exchanger 21 with immersion in the sea water or inspection or maintenance positions can be adjusted flexibly.
- a particularly efficient and heat sink is realized by the seawater, so that process heat from the electrolysis can be derived from the container (2) and the seawater can only be supplied via convection. Due to the closed coolant circuit (3), there is no damaging exchange of substances between the coolant circulated in the circuit and the seawater. These areas are fluidically separated from each other.
- the heat exchanger 21 has a pipe which is equipped with ribs and/or fins on the coolant-carrying pipe outer surface and/or is guided in a large number of pipe bends. This specific and particularly advantageous embodiment is not illustrated in more detail in FIG. 3 for reasons of clarity.
- the pipeline is made of steel and has an anti-corrosion layer on the outer surface.
- the invention thus provides for the use of seawater as a heat mesenke in an almost unlimited reservoir as a cooling medium, with a closed coolant circuit (3) only the heat is transferred to the sea water by the heat exchanger (21) immersed in the sea and is given off to this.
- a closed coolant circuit (3) only the heat is transferred to the sea water by the heat exchanger (21) immersed in the sea and is given off to this.
- large cooling capacities for offshore electrolysis can be realized and large heat flows from high-performance offshore electrolysers can be transferred to the seawater via the coolant.
- the impact of this construction from an environmental point of view is minimal, particularly since the coolant and seawater are materially decoupled.
- the numerous problems described during operation are avoided, in particular because no seawater is sucked in and instead there is a closed coolant circuit 3 . No foreign bodies can be sucked in, no undesirable inorganic layers or biofouling can form inside the heat exchanger 21, which increases operational reliability.

- FIG. 4 shows a further exemplary embodiment in a particularly advantageous embodiment of an offshore electrolysis system 20 according to the invention.
- the frame 22 with the heat exchanger 21 is fastened in such a way that, if necessary, it can be led out, tilted out or folded out of the sea water.
- a rotatable attachment 24a of the structural unit, comprising the frame 22 with the large-area heat exchanger 21 on the structure 10 is provided.
