In Osterweddingen near Magdeburg, the energy transition is entering its next phase: a hydrogen plant is currently being built in the local industrial park, which will supply local industrial companies with green hydrogen in the future. In the first stage of expansion, around 900 tons of green hydrogen per year are to be produced using a 10 MW PEM electrolyzer. The electrolyzer will be operated in a system-friendly manner to compensate for fluctuations in electricity generation from wind and solar power, thereby stabilizing the power grid. The electrolyzer is operated in a way that benefits the system, balancing out fluctuations in electricity generation from wind and solar power and thus reducing the load on the power grid. The green hydrogen will be used to decarbonize industry, as fuel for long-distance freight transport, for feeding into hydrogen pipelines, and, in the long term, for generating electricity during periods of low wind and solar power generation.
