Worldwide Hydrogen Production, at a Glance

in 2021


of worldwide Hydrogen Production came from Black & Brown, Grey or Blue Hydrogen.

Black or Brown Hydrogen Generated from different types of coal.
Grey Hydrogen Created when natural gas is split into hydrogen and CO2 usually through steam methane reformation – SMR.
Blue Hydrogen Also derived from natural gas but in this case the CO2 emissions are captured to be either used in industrial processes or stored underground using carbon capture utilisation and storage – CCUS.
