European renewable giant Vattenfall said that if it wins the tender for its lot at Hollandse Kust West, the company will build the world’s first hydrogen cluster as part of an offshore wind farm there. Three wind turbines will be equipped with electrolysers. The hydrogen they produce will be transported via a pipeline to the Port of Rotterdam and fed into the hydrogen network there. The hydrogen will then be transported to users via a network of pipes, in the same way as with natural gas. In the hydrogen cluster, which consists of three turbines, containers are placed on special platforms. These containers are filled with electrolyser modules, transformers and batteries. When working in tandem, these containers make it possible to convert the generated electricity in the wind turbines into hydrogen. The planned total capacity for the cluster is 45 MW.There are various plans for onshore hydrogen plants, but comparatively few for offshore production. In addition, it will ease pressure on the overloaded onshore electricity grids. Hydrogen will become an important part of the energy mix as part of a fossil-free energy supply. This is essential for the ongoing transition to a sustainable energy supply and increasing electrification. Earlier this year, Vattenfall received subsidies from the Scottish government to develop the world’s first hydrogen turbine off the coast of Aberdeen. Vattenfall wants to use Hollandse Kust West as a springboard for taking the next step and connecting multiple hydrogen turbines.Several new wind farms will be built off the coast of the Netherlands in the coming years. The next one scheduled for construction is Hollandse Kust West. The project consists of two parts, lot VI and lot VII, with lot VII primarily being assessed for system integration, i.e. plans to align the energy system of the future as closely as possible. Vattenfall is competing in both lots. The winner of the construction contract will be announced after the summer.
