Quest One and MAN Energy Solutions have initiated the construction of a large-scale PEM electrolyzer demonstration plant in Augsburg, Germany. This joint project aims to optimize plant operations and refine the service concept through test operations and field data. The demonstration plant will provide valuable insights into the construction phases, dimensions, inner workings, and infrastructure of large electrolyzers. It is expected to be operational by mid-2025, allowing visitors to experience the technology firsthand. The collaboration emphasizes the importance of industrial-scale electrolyzers to meet the rising demand for green hydrogen, with a focus on decarbonizing the industrial sector. The project also seeks to continuously enhance the performance and operating parameters of the Modular Hydrogen Platform, a scalable system designed for industrial hydrogen production. Supported by the PEP.IN research project, funded under the H2Giga hydrogen lighthouse initiative, the development of the demonstration plant aims to drive advancements in PEM electrolyzer series production to make green hydrogen more cost-effective and competitive. Overall, the project highlights a significant step towards sustainable hydrogen production and industrial decarbonization.
