In sectors where it is difficult (or even impossible), use of low-carbon hydrogen will be a key driver for achieving carbon neutrality... Hydrogen is a form of energy, a fuel, but also a raw material for many heavy industries such as refining, chemicals, glass, etc... Where direct electrification of uses is still technologically difficult, if not impossible, or not economically profitable, use of decarbonised hydrogen can play a key role in achieving carbon neutrality.
