BASF's largest proton exchange membrane (PEM) electrolyzer in Germany has commenced operations at its Ludwigshafen site, designed to produce zero-carbon hydrogen. With a connected load of 54 megawatts, the electrolyzer can supply up to one metric ton of hydrogen per hour to the main plant. The inauguration of the plant was attended by notable figures like the Rhineland-Palatinate State Minister for Climate Protection and the State Secretary at the German Federal Ministry for Economic Affairs and Climate Action. Built in partnership with Siemens Energy, the electrolyzer is integrated into the Ludwigshafen site's production and infrastructure, containing 72 stacks for the electrolysis process. This initiative aligns with BASF's goal to reduce greenhouse gas emissions by 72,000 metric tons annually at its main plant. The green hydrogen will be utilized as a feedstock for chemical products and to support the local hydrogen economy for mobility. The Hy4CHem project received funding of €124.3 million, with BASF contributing approximately €25 million. The collaboration signifies a significant step towards decarbonization in the industrial sector and showcases the potential of green hydrogen production in a chemical environment. The project has garnered praise from various officials for its role in advancing the hydrogen economy and achieving climate targets, emphasizing the importance of such technological progress in the industry.
