Vallhyège is a hydrogen ecosystem project comprising two facilities at two separate sites. A 15 MW renewable hydrogen production site using electrolysis, located in Engis, capable of filling Tube Trailers and MEGCs. The site will be able to accommodate 50 MW of electrolysis, and this additional hydrogen will be distributed via the future Fluxys pipeline. The project also includes a hydrogen refuelling station within Trilogiport, primarily to refuel heavy duty trucks. The station has a refuelling capacity of 2.2 tonnes of hydrogen at 350 and 700 bar to accommodate all types of vehicles.
