Green WaHyVe - The Walloon hydrogen Valley

Country
Belgium

The primary objective of the Green WaHyVe project is to scale up and strengthen the existing local hydrogen valley, Vallhyège, transitioning from initial deployment to industrial-scale production and use of renewable hydrogen in both mobility and energy-intensive industries. By leveraging a proven foundation in heavy-duty mobility, the project aims to significantly expand demand and accelerate the market uptake of clean hydrogen across different sectors (industry, flexibility and special uses)
