Air Liquide announced that it is planning to build in Oberhausen, Germany, a renewable hydrogen production plant by electrolysis. With a total capacity to reach 30 megawatts (MW), a first phase of the project is expected to be operational by early 2023 with 20 MW. What is unique about this project is that the electrolyzer will be integrated into the existing local pipeline infrastructure of Air Liquide to supply key industries and mobility with renewable hydrogen in one of the most industrialized regions of Germany. To accelerate the implementation of this project, public funding has been granted by the German Federal Ministry of Economic Affairs and Energy. This worldscale electrolyzer will be the first to be built in the framework of the partnership between Air Liquide and Siemens Energy. The new Proton-Exchange Membrane (PEM) electrolyzer to be built by Air Liquide will produce renewable hydrogen from water and renewable electricity. The technological solution for the project is being developed in the framework of the previously announced partnership between Air Liquide and Siemens Energy. By 2023, the two partners will implement a 20 MW electrolyzer plant that will produce renewable hydrogen and renewable oxygen. In a second phase, Air Liquide has planned to increase the plant capacity to 30MW. The PEM electrolysis is expected to start operating in early 2023 and will be the first large-scale renewable hydrogen production connected to both existing hydrogen and oxygen pipelines, with nearly 15 large industrial sites already connected today. This will support sectors such as Steel, Chemicals, Refining and Mobility in North Rhine-Westphalia by accelerating the availability of gases produced with renewable electricity for their efforts to reduce their carbon footprint.
