German companies NorthH2, DOTI, and the Offshore-Windenergie Foundation have announced plans to collaborate on building a 10 MW offshore electrolyzer demonstrator at the Alpha Ventus wind farm in the North Sea. This initiative is part of the NORTHSEA Hydrogen project pipeline developed by NorthH2. The project aims to demonstrate the feasibility and efficiency of hydrogen production directly at sea by utilizing power generated by the wind farm for the proton exchange membrane electrolyzer. The electrolyzer will use power from Alpha Ventus to desalinate seawater, split it into hydrogen and oxygen, and explore reconversion during low-wind periods. The partners are investigating options for using the hydrogen produced at sea, considering future connectivity through the AquaDuctus pipeline. The project intends to provide crucial insights for operating offshore electrolyzers commercially, testing components under real conditions, and establishing regulatory frameworks. Andreas Wellbrock of NorthH2 emphasized the importance of this demonstrator in enhancing hydrogen production efficiency and sustainability. Karina Würtz of the Offshore-Windenergie Foundation highlighted the need to address technical and economic challenges in the offshore hydrogen sector. The partners aim to test the technology under North Sea conditions and optimize maintenance requirements. Overall, the project signals a positive step towards promoting green energy and overcoming challenges in offshore hydrogen production.
