Abstract

The invention relates to an offshore electrolysis plant including an electrolyzer, which is disposed in a container, and a heat exchanger, which is designed to absorb process heat from the electrolysis and to discharge said process heat out of the container in a closed coolant circuit. A coolant pump for conveying the coolant in the coolant circuit is disposed in the container. The invention also relates to a method for operating an offshore electrolysis plant having an electrolyzer disposed in a container. In the method, in order to absorb process heat from the electrolysis and to discharge said process heat out of the container, coolant is conducted in a closed coolant circuit, wherein a coolant pump disposed in the container is operated.

First claim

1 . An offshore electrolysis plant comprising an electrolyzer arranged in a container and a heat exchanger, which is designed for heat absorption and discharge of process heat from the electrolysis in a closed coolant circuit from the container, characterized in that a coolant pump for conveying the coolant in the coolant circuit is arranged in the container.

2 . The offshore electrolysis plant as claimed in claim 1 , in which a heat exchanger, which is immersible in the ocean, is provided in the closed coolant circuit for the heat dissipation of the process heat absorbed by the coolant.

3 . The offshore electrolysis plant as claimed in claim 2 , in which to provide a large heat exchanger surface, the heat exchanger has a pipeline, which is embodied having ribs and/or fins on the coolant-guiding pipe outer surface and/or is guided in a large number of pipe curves.

4 . The offshore electrolysis plant as claimed in claim 3 , in which the pipeline is made of steel, wherein the pipeline has a corrosion protection layer on the outer surface.

5 . The offshore electrolysis plant as claimed in claim 4 , in which the corrosion protection layer comprises titanium.

6 . The offshore electrolysis plant as claimed in claim 2 , wherein the heat exchanger is arranged in a framework, which encloses the heat exchanger and holds the heat exchanger in position for the respective operating state via fasteners.

7 . The offshore electrolysis plant as claimed in claim 6 , in which the framework having the heat exchanger is fastened such that if needed guiding or tilting out of the ocean water can be effectuated.

8 . The offshore electrolysis plant as claimed in claim 6 , in which the framework having the heat exchanger can be tilted out via a rotatable fastener.

9 . The offshore electrolysis plant as claimed in claim 1 , having a connection unit for feeding electric current from an offshore wind turbine.

10 . A method for operating an offshore electrolysis plant having an electrolyzer arranged in a container, in which coolant is guided out of the container in a closed coolant circuit for the heat absorption and discharge of process heat from the electrolysis, wherein a coolant pump arranged in the container is operated.

11 . The method as claimed in claim 10 , in which heat is transferred to ocean water in the closed coolant circuit from the coolant heated by the process heat and the coolant is thus cooled.

12 . The method as claimed in claim 10 , in which a damaging penetration of ocean water into the coolant circuit is monitored.
