The Colours of Hydrogen Fuel Explained
Brown H2
- Brown Hydrogen is made from coal gasification.
- The process releases CO2 into the atmosphere.
- Production costs are from $1.2 to $2.1 per kg h2.
- Brown Hydrogen has the highest GHG emissions of 19t CO2 / tH2.

Grey H2
- Grey Hydrogen is made from steam methane reforming.
- The process releases CO2 into the atmosphere.
- Production costs are from $1 to $2.1 per kg h2.
- Grey Hydrogen has high GHG emissions of 11t CO2 / tH2.

Blue H2
- Blue Hydrogen is made from advanced gas reforming.
- The process injects carbon into a formation with some release of CO2 into the atmosphere.
- Production costs are from $1.5 to $2.9 per kg h2.
- Blue Hydrogen has low GHG emissions of 0.2t CO2 / tH2.

Advanced Gas Reformation
Green H2
- An electrolyser is a device that uses renewable energy to convert water into green hydrogen, a powerful fuel of the future that will help decarbonise hard to abate sectors.
- Green hydrogen holds the key to tackling climate change, but only if the hydrogen is made using 100% renewable energy sources, like wind, solar, geothermal, and hydro power.
- The process produces Zero CO Emission's
