Rolls-Royce is coming into the hydrogen manufacturing market and buying a 54% majority stake in electrolysis stack specialist Hoeller Electrolyzer. The Hoeller expertise will type the premise of a brand new vary of mtu electrolyzer merchandise from the Rolls-Royce Energy Methods division.
Hoeller Electrolyzer, based mostly in Wismar, Germany, is an early-stage expertise firm that’s growing extremely environment friendly polymer electrolyte membrane (PEM) stacks, underneath the model identify Prometheus, for the cost-effective manufacturing of hydrogen.
Rolls-Royce’s first mtu electrolyzer will go into demonstrator operation in 2023. The core component is the electrolysis stack from Hoeller Electrolyzer, wherein Rolls-Royce has a 54% stake.
Demand for inexperienced hydrogen is anticipated to rise considerably. It’s wanted for gasoline cells and hydrogen engines, for the manufacturing of artificial drop-in fuels and for industrial processes that presently use hydrogen that’s not created in a carbon impartial course of. Consequently, high-performance electrolyzers are a key part of any hydrogen system.
By growing our personal mtu electrolyzers and by taking a majority stake in Hoeller Electrolyzers, we’re methodically rising our hydrogen portfolio and securing entry to this fascinating expertise, which isn’t a pipe dream however has nice market potential. This may allow us to provide full hydrogen options and make a big contribution to defending the local weather. Our full hydrogen options will allow prospects to retailer renewably produced vitality within the type of hydrogen to be used as and when required, or for additional processing or onward sale.
—Dr. Otto Preiss, COO and Chief Know-how Officer, Rolls-Royce Energy Methods
Based in 2016, Hoeller Electrolyzer has positioned itself, with Prometheus, as a participant within the area of high-efficiency PEM electrolysis stacks. Its founder, Stefan Höller, has greater than 1 / 4 of a century’s expertise of growing electrolysis expertise and has already registered 14 patents related with Prometheus. Notably excessive effectivity is promised by particular floor applied sciences for the bipolar plates which considerably cut back the usage of costly valuable metals platinum and iridium as catalysts, in addition to elevated output stress.
Our stack goes to provide hydrogen at a worth not beforehand thought doable.
—Stefan Höller, Managing Director, Hoeller Electrolyzer
Improvement work on the primary mtu electrolyzer utilizing a stack from Hoeller Electrolyzer is already underway. In 2023, it is going to go into operation on the Validation Middle in Friedrichshafen to exhibit how an electrolyzer matches into the general structure of a microgrid. An preliminary buyer venture is already deliberate for 2024.
We’re going to launch electrolyzers with a number of megawatts of energy proper from the beginning. A complete output of over 100 megawatts is conceivable by combining a number of electrolyzers.
—Armin Fürderer, who heads up the Internet Zero Options enterprise unit of Energy Methods
The fairness in Hoeller Electrolyzer now held by Rolls-Royce comes from departing minority shareholders and from a rise in share capital. Monetary particulars of the transaction usually are not being disclosed. Stefan Höller and Matthias Kramer will proceed to guide Hoeller Electrolyzer as a standalone firm, with the purpose of constructing a number one worldwide stack producer.
