Grey Hydrogen is produced through steam methane reforming, which is the most common form of hydrogen production. It generates a significant amount of CO₂ emissions.
Brown Hydrogen
Brown Hydrogen is made from coal gasification, producing even higher CO₂ emissions than grey hydrogen, making it one of the most carbon-intensive forms of hydrogen.
Blue Hydrogen
Blue Hydrogen is derived from natural gas through steam reforming, with carbon capture and storage (CCS) technology used to reduce CO₂ emissions.
Turquoise Hydrogen
Turquoise Hydrogen is produced through methane pyrolysis, which splits natural gas into hydrogen and solid carbon, reducing CO₂ emissions compared to grey and brown hydrogen.
Pink Hydrogen
Pink Hydrogen is hydrogen produced through the electrolysis of water using electricity generated from nuclear power.
Green Hydrogen
Green Hydrogen is produced through electrolysis of water using renewable energy sources like solar or wind power, resulting in zero carbon emissions.
