Electrolysis systems for several megawatts of powerFirst demonstrator in 2023 using a Hoeller stackRolls-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.Hydrogen is an increasingly attractive power source to fuel the green energy transition and demand for ‘green’ hydrogen – whose production creates no CO2 – is expected to rise significantly. It is needed for fuel cells and hydrogen engines, for the production of synthetic…
