Hydrogen pathways depend on local circumstances

Hydrogen is viewed as a contributor to decarbonisation in an increasing number of countries around the world. But national strategies to build out the sector vary considerably

It is widely acknowledged that hydrogen has the ability to contribute to the decarbonisation of the energy and industrial markets and therefore assist with global efforts to meet emissions control requirements. But for the foreseeable future there will be continued debate about the relative contribution of the various ways to produce hydrogen, differentiated by an associated colour from a palette relating to the environmental credentials of feedstocks and production methods. For the short- to mid-term, the consensus appears to favour investment in blue hydrogen, derived from natural gas with CO₂ abatement. However, this moves in the longer term to an ever-increasing contribution of green hyd
