Rolls-Royce is entering the hydrogen production market and acquiring a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer, whose innovative technology will form the basis of a new range of mtu electrolyzer products from its Power Systems division. Hoeller Electrolyzer, based in Wismar, Germany, is an early-stage technology company that is developing highly efficient polymer electrolyte membrane (PEM) stacks, under the brand name Prometheus, for the cost-effective production of hydrogen.
Rolls-Royce and Hoeller Electrolyzer are united by a shared belief in the opportunity of zero-carbon energy – both for power supply and the propulsion of heavy vehicles. With decades of experience and systems expertise, Rolls-Royce is going to develop a complete electrolyzer system and has a global sales and service network, which opens up the potential for significant worldwide sales.
Development work on the first mtu electrolyzer using a stack from Hoeller Electrolyzer is already underway. In 2023, it will go into operation at the Validation Center in Friedrichshafen to demonstrate how an electrolyzer fits into the overall architecture of a microgrid. An initial customer project is already planned for 2024.
