The Castilla y León Hydrogen Valley project has been launched in Burgos, Spain, as a groundbreaking initiative to establish a fully integrated green hydrogen ecosystem. With a total investment of €380 million, including substantial backing from the EU's Clean Hydrogen Partnership, the project aims to play a vital role in Europe's clean energy transition and industrial decarbonization. The initiative, led by CARTIF and the Castilla y León Hydrogen Association (H2CYL), brings together 35 partners from nine European countries to build a complete hydrogen value chain from production to end use. At the heart of the project is the goal to produce over 16,800 tonnes of green hydrogen annually, leveraging the region's significant renewable resources, particularly its 7,200 MW of wind power capacity. This production is expected to lead to a reduction of up to 152,000 tonnes of CO₂ emissions per year, contributing to the region's energy security and reducing dependency on fossil fuels. The project will focus on various key areas, including the production of sustainable chemicals, energy-intensive industry decarbonization, zero-emission mobility through hydrogen-powered vehicles, and the establishment of hydrogen refueling infrastructure. Over its five-year lifespan, the project is set to generate 2,000 jobs, boosting economic growth and promoting innovation in the region. By collaborating with stakeholders across the EU, the Castilla y León Hydrogen Valley project will share best practices, technical insights, and policy guidance to contribute to the European Hydrogen Backbone. The project will also work on developing transnational hydrogen corridors to seamlessly integrate green hydrogen into Europe's energy networks. With a positive sentiment towards hydrogen, the project aims to highlight hydrogen as a cornerstone of the green economy with a strong focus on sustainability and innovation.
