Building one of Europe’s largest Hydrogen Valleys to drive decarbonisation, innovation and sustainable growth.
The Castilla y León Hydrogen Valley project is a co-funded European initiative aimed at developing and demonstrating a large-scale hydrogen ecosystem in the Castilla y León region of Spain. The project integrates applications across mobility,
industry, and energy.
By 2028–2029, Castilla y León Hydrogen Valley aims to be fully operational, proving the financial viability and technical versatility of clean hydrogen as a cornerstone of the energy transition.
Castilla y León Hydrogen Valley includes 11 pilot sites across Castilla y León, each demonstrating a key element of the hydrogen value chain — from production and distribution to end use in transport, industry, and energy. Together, they form an integrated ecosystem proving the versatility and scalability of green hydrogen.
