The Müllerhütte is an off-grid cabin situated above 3,000 m and can only be reached on foot or by helicopter. In the past, the necessary energy was provided by a generator run on diesel transported by helicopter. The Müllerhütte wants to generate its own CO2-free energy, store it and use it during summer days, when it is open, to achieve 100% self-sufficiency and replace the diesel generator. GKN Hydrogen planned the modular construction of a hydrogen storage system based on metal-hydride technology. This system allows Müllerhütte to store the electricity in the form of electrolytic hydrogen produced by photovoltaics safely and compactly. A hydrogen storage system at an altitude of over 3,000 m makes this project unique. The major challenges faced by the storage unit of this project are robustness (altitude, temperature, and transport), modularity, light weight and remote control of the energy management system on the glacier.
