Adele Hydrogen is proud to contribute its Pathfinder electrode technology to Alpine Hydrogen, a project submitted under the EU Hydrogen Bank auction to supply green hydrogen to industrial customers in Tyrol, Austria.
The project brings together Green Hydrogen Development & Investment GmbH, Adele Hydrogen SAS, and RCT GH Hydrogen with a shared ambition: combine robust alkaline electrolysis with breakthrough electrode performance to improve the economics of green hydrogen production in Europe. According to recent public coverage, the project targets approximately 500 tonnes of green hydrogen per year and could reduce CO2 emissions by more than 4,000 tonnes annually.
For Adele Hydrogen, the key message is clear. Pathfinder electrodes do not only improve electrolysis performance. They also change the design equation of the plant itself. By enabling much higher rated capacity from the same stack size, Pathfinder makes it possible to conceive electrolyser installations that are significantly more compact. This can reduce capex per installed MW while increasing hydrogen output from a given footprint.
This performance gain must go hand in hand with flexibility. A cost-competitive hydrogen asset is not just efficient at nominal load. It must also respond to the power system it is connected to. With Pathfinder, alkaline electrolyser installations can operate more dynamically, which improves their ability to benefit from volatile electricity prices and balancing opportunities. In practical terms, this supports lower production costs and a path toward best-in-class LCOH.
Recent reporting on Alpine Hydrogen highlighted that Adele Hydrogen’s electrode materials can increase electrolysis performance by 250% and allow alkaline systems to operate at 5 MW instead of 2 MW on the original platform, while reaching up to 1,000 Nm3 of hydrogen production per hour. It also underlined the value of greater process flexibility for grid integration and balancing services.
At Adele Hydrogen, we believe this is exactly where the market is going. Green hydrogen projects must be designed not only for efficiency, but for compactness, flexibility, and superior economics in real operating conditions.
Alpine Hydrogen is an important illustration of that vision in action.
