The Clean Hydrogen Coastline Programme is an integrated infrastructure initiative focusing on the real-world deployment of clean hydrogen along the entire value chain. It comprises several interconnected sub-projects covering hydrogen production through large-scale electrolysis, underground storage, and dedicated transport infrastructure. By developing and linking these elements under practical conditions, the programme aims to translate strategic hydrogen ambitions into operational projects. It addresses technical, regulatory, and organizational challenges that arise when implementing hydrogen infrastructure at scale. The Clean Hydrogen Coastline Programme therefore serves as a practical reference for future hydrogen developments and contributes concrete experience to the broader energy transition.
