Description du projet
Augmenter la pression pour trouver des solutions de ravitaillement en hydrogène
Le recours à l’hydrogène en tant que carburant pourrait décarboner de nombreux secteurs qui dépendent actuellement des hydrocarbures pour leur énergie. Le secteur des transports est une application particulièrement prometteuse, mais en plus du développement de véhicules fonctionnant à l’hydrogène, nous devons disposer d’une infrastructure de ravitaillement en hydrogène à grande échelle. L’unité de compression ou unité de stockage à haute pression est le principal composant d’une station de ravitaillement en hydrogène. Sa fonction est d’augmenter la densité énergétique ou la quantité d’énergie dans un volume donné afin que ces véhicules puissent parcourir de longues distances. Stocker et fournir du carburant pour les grandes flottes d’autobus, de trains et de camions est encore plus difficile. Le projet COSMHYC XL, financé par l’UE, développe une solution de compression modulaire et scalaire innovante pour répondre aux différents besoins des stations de ravitaillement en hydrogène de très grande taille.
Objectif
Hydrogen mobility is one of the most promising solutions for a sustainable energy transition in large-scale transport modes, including trucks, busses, trains and professional vehicle fleets. For these applications, a dedicated hydrogen refuelling infrastructure is necessary, including hydrogen compressors able to meet challenging constraints in terms of flow rate and availability. The COSMHYC XL project aims at developing an innovative compression solution for extra large hydrogen refuelling stations, based on the combination of a metal hydride compressor and a diaphragm compressor. The solution will be scalable and modular and will therefore be adapted to the diversity of large-scale mobility applications. The combination of both technologies will provide a cost efficient solution, by reducing both the investment and the maintenance costs. Thanks to significant research and innovation activities, from core materials and components to system integration, the new compression solution will contain no critical raw materials. The hydrogen flow rates will be drastically increased, as well as the overall compression ratio. In addition, the reliability and availability of hydrogen refuelling stations will be significantly improved. An innovative system integration concept will enable to optimise the thermal synergies between both compressors and lead to an improved electrical efficiency by more than 30%, thereby contributing to reduce the production costs of hydrogen and making it a competitive fuel for large-scale mobility. COSMHYC XL will include the development of a 1/10 scale prototype, and a long-term test phase of 6 months under real conditions. Techno-economic analysis will be performed and an advisory committee will support the partners to better understand the needs of the market. Extensive communication, dissemination and exploitation activities will take place and maximise the economic, environmental and societal impacts of the project.
