The development of the green hydrogen industrial clusters requires multi-stakeholder engagement and coordination in the design of the overarching policy framework and in its implementation. These guidelines provide information on its development and dialogues among government, the private sector and academia. They are published with the aim to support the establishment of the GHIC, leveraging a versatile and scalable model. As a result, the clusters will promote the uptake of green hydrogen in local industry, its decarbonization and the development of new low-carbon industries, all contributing to achieving inclusive and sustainable industrial development and the Nationally Determined Contributions (NDCs) under the Paris Agreement.
