Under the new acquisition, Hoeller Electrolyzer’s technology will form the basis of a new range of mtu (Rolls Royce’s Power System Business Unit) electrolysers, with the companies saying development work is already underway.
H2 View understands in 2023, the mtu electrolyser will go into operation at Rolls Royce’s microgrid Validation Centre in Friedrichshafen, Germany, to demonstrate how an electrolyser will fit into the overall microgrid system, with an initial customer project already planned for 2024.
The mtu electrolysers are set to be launched at ‘several megawatt’ scale, with a total output of over 100MW achieveable by combining several electrolysers, according to Armin Fürderer, Head of Net Zero Solutions business unit of Power Systems at Rolls-Royce.
Hoeller Electrolyzer, based in Wismar, Germany, is said to be in the early-stage of developing ‘highly efficient’ polymer electrolyte membrane (PEM) stacks under the brand name Prometheus.
Dr. Otto Preiss, Chief Operating Officer and Chief Technology Officer, Rolls-Royce Power Systems, said, “By developing our own mtu electrolysers and by taking a majority stake in Hoeller Electrolyzers, we are methodically growing our hydrogen portfolio and securing access to this fascinating technology, which is not a pipe dream but has great market potential.
“This will enable us to supply complete hydrogen solutions and make a significant contribution to protecting the climate. Our complete hydrogen solutions will enable customers to store renewably produced energy in the form of hydrogen for use as and when required, or for further processing or onward sale.”
In November 2021, Rolls-Royce announced it was expanding its partnership on hydrogen fuel cells with cellcentric, by developing complete mtu hydrogen fuel cell solutions.
Matthias Kramer, Chief Financial Officer and Joint Managing Director of Hoeller Electrolyzer, commented, “In Rolls-Royce, not only have we found an important customer for our stacks, we have also secured an ideal partner and supporter who shares our vision of putting stacks into full production.”
