BASF has successfully inaugurated Germany's largest proton exchange membrane (PEM) electrolyzer at its Ludwigshafen site, marking a significant milestone in the production of zero-carbon hydrogen. With a connected load of 54 megawatts and an annual capacity of up to 8,000 metric tons, the electrolyzer is designed to supply the main plant with a substantial amount of green hydrogen. The project, named Hy4CHem, received substantial funding of €124.3 million from the German Federal Ministry for Economic Affairs and Climate Action and the State of Rhineland-Palatinate, with an additional investment of around €25 million from BASF. The integration of the water electrolyzer into the chemical production environment at Ludwigshafen showcases a direct and innovative approach towards reducing greenhouse gas emissions by up to 72,000 metric tons per year. Beyond serving as a chemical feedstock, the green hydrogen produced will also be utilized for mobility applications in the region, supporting the development of a hydrogen economy. Government officials and BASF representatives have highlighted the importance of this project in achieving climate targets and driving the transformation towards a more sustainable industrial sector. The collaboration between BASF, Siemens Energy, and governmental bodies emphasizes the commitment towards decarbonization and technological progress in the hydrogen sector. The green hydrogen initiative at Ludwigshafen not only signifies a step towards climate-neutral chemical production but also sets an example for future green hydrogen projects within the industry.
