Germany has achieved a major milestone in hydrogen production with the inauguration of the country's largest proton exchange membrane (PEM) electrolyzer at BASF's Ludwigshafen site. This electrolyzer, designed to produce zero-carbon hydrogen, has a significant 54 MW capacity, allowing it to supply one metric ton of hydrogen per hour to the main plant. The integration of the electrolyzer into the chemical production environment is a global first, with 72 stacks installed to reduce BASF's greenhouse gas emissions by up to 72,000 metric tons annually. The project, named Hy4CHem, received substantial funding of €124.3 million from the German government and BASF, signifying their commitment to sustainability and innovation. BASF plans to utilize the hydrogen as a chemical feedstock and support a hydrogen economy in the region, highlighting their dedication to reducing carbon footprints and promoting climate action.
