The first molecule of green hydrogen was produced by a 30-megawatt (MW) German energy plant powered by a 50MW wind farm, according to an announcement on Tuesday, November 10.The latest milestone marks the start of integrated system testing, with all major components now operating together ahead of the plant’s full commissioning in 2027.Calling it “an important milestone,” Holger Kreetz, COO of Uniper, one of the companies leading the project, said, “the hydrogen economy needs more than electrolyzers…it is crucial that the entire process chain functions reliably in operation.”Wind-powered electrolysisThe system uses renewable electricity from the connected wind farm to split water into hydrogen and oxygen, a process called electrolysis. The process is carried out in a pressure-alkali electrolyzer comprising three modules, each with a capacity of 10 MW. The electrochemical conversion of water into hydrogen and oxygen takes place inside the stacks, two of which are present in each module.According to the company, the green hydrogen produced as a part of this project will be fed into Central Germany’s industrial hydrogen pipeline network, supplying chemical manufacturers and, in the future, supporting hydrogen-powered urban transportation.Green hydrogen was produced more than three years after construction began at the Bad Lauchstädt Energy Park near Leipzig. The plant is expected to become fully operational next year.Upon completion, the project is expected to produce up to 3,000 tons of green hydrogen per year. Almost 75 percent of the annual green hydrogen production from the fully operational plant would be supplied via a 15-mile (25-kilometer) pipeline to TotalEnergies, a refining and petrochemical facility at the Leuna Chemical Complex.”With the production of the first hydrogen, we are getting closer to our common goal of transferring renewable energy into an industrially usable energy source,” said Konstantin von Oldenburg, Managing Director of VNG H&V.However, two partner energy companies, Uniper and VNG Handel & Vertrieb (VNG H&V), which are leading the project, have not revealed a firm timeline for reaching the plant’s full production capacity.Future directionWith the plant now producing its first hydrogen, engineers will focus on fine-tuning the integrated system before it enters commercial operation.The next phase will focus on optimizing how electricity generation, electrolysis, gas treatment, and hydrogen transport work together under real-world operating conditions while coordinating the plant’s technical processes.Moving forward, the pipeline infrastructure is expected to connect the wider hydrogen core network of Germany, spread across nearly 5600 miles (9000 kilometers). According to the statement, for this wide-scale expansion, salt cavern storage could be added to the site in the later phase of the project.Besides the German plant, advances in green hydrogen technology are also underway in the Middle East, with Saudi Arabia set to become a world leader in clean energy technology. In September this year, the construction of the world’s largest green hydrogen facility was completed in the country. NEOM Green Hydrogen and Ammonia project is one of the most ambitious green-hydrogen developments ever undertaken.Once operational, the facility will produce up to 600 tons per day of carbon-free hydrogen, converted into green ammonia for global export, providing a practical blueprint for green hydrogen at scale.
