Risks in the design of regional hydrogen hub systems: A review and commentary. [PDF]
Risk AnalAbstract Early investments in regional hydrogen systems carry two distinct types of risk: (1) economic risk that projects will not be financially viable, resulting in stranded capital, and (2) environmental risk that projects will not deliver deep reductions in greenhouse gas emissions and through leaks, perhaps even contribute to climate change.
