The concept of hydrogen hubs (or hydrogen valleys or clusters) is included in many global hydrogen strategies and roadmaps as an important mechanism to accelerate large-scale hydrogen industry development. Hub focussed developments make the development of common user infrastructure more cost-effective, promote efficiencies from economies of scale, foster innovation, and promote synergies from sector coupling.

A development opportunity centred around hubs encompasses a blend of elements, such as:

• Geographically defined scope, a hydrogen ecosystem that covers a specific geography.
• Substantial infrastructure facilities supportive of sizeable export and domestic hydrogen industry development.
• Broad value chain coverage, covering multiple steps in the hydrogen value chain.
• Supply of more than one end use, supplying more than one sector or application.
