RCT Hydrogen, based in Konstanz, is starting the production of electrolysis systems for industrial hydrogen production at the Saarbrücken site. Manufacturing takes place at Brück GmbH, a manufacturer of forged and ring products for the mechanical engineering, energy, and wind power sectors. According to their own statements, both companies have signed cooperation agreements.
The annual production capacity is expected to be 250 MW. According to the company, the assembly of a 5 MW electrolyser will begin in June 2026. Delivery and commissioning at a German industrial customer are planned for 2026. Further systems with an electrolysis capacity of over 30 MW are in planning according to RCT Hydrogen. At Brück, the electrolyser stacks, which form the heart of the systems, are manufactured. The company intends to bring its experience from plant construction for oil and gas production.
Alkaline pressure electrolysis with a Chinese technology partner for hydrogen costs under 5 euros per kilogram
RCT Hydrogen relies on alkaline pressure electrolysis. Key components are supplied by the Chinese partner Guofuhee. According to the company, the essential manufacturing steps are to take place in Germany and Europe. The technology is TÜV-tested. Dr. Eric Rüland, Vice President Sales and Products at RCT Hydrogen, states a target price: "The high efficiency combined with the long service life of the electrolysis systems is a decisive competitive advantage for customers. This reliably brings low costs for green, CO2-free hydrogen of under 5.00 EUR per kilogram."
The companies RCT and Guofuhee are also linked in their corporate structure. Behind RCT Hydrogen is the Konstanz-based RCT GH GmbH. According to a public stock document, RCT GH is controlled by RCT Holding; the remaining 49 percent is held by GF Hydrogen Europe, the European company of Guofuhee.
Demonstration plant planned at the production site
A demonstration plant with a capacity of 2.5 MW is also planned at the Saarbrücken site. The hydrogen produced there is intended to replace natural gas in high-temperature processes. "We see the opportunity to use hydrogen in production here. This would be a first step away from fossil fuels in the industrial production of forged steel parts," says Frederic Scholl, Head of Business Development at Brück.
According to its own statements, RCT Hydrogen markets the systems in a "Hydrogen-as-a-Service" model. Industrial customers produce the hydrogen at their own site and use it directly on-site. In addition to industrial plants in the range of 1 to 5 MW, the company also wants to serve large projects from 100 MW.
