Blue hydrogenis hydrogen produced from natural gas with a process of steam methane reforming, where natural gas is mixed with very hot steam and a catalyst. A chemical reaction occurs creating hydrogen and carbon monoxide. Water is added to that mixture, turning the carbon monoxide into carbon d...
hydrogen. Carbon emissions generated during this process are captured and stored, rather than being released into the atmosphere. This makes blue hydrogen a lower-carbon alternative to traditional grey hydrogen where the emissions are not captured, though it still produces some carbon emissions whe...

The dominant benchmark method of hydrogen production issteam methane reforming(SMR). A modern SMR plant producesbetween nine and 11kg CO₂e per kg hydrogen; this is “grey” hydrogen. Adding conventional carbon capture and storage to SMR (to produce “blue hydrogen”) can reduce the carbon i...
‘Grey’ vs ‘Blue’ hydrogen Speed is of the essence when it comes to decarbonizing energy-intensive industries. The United Nations warned in October the world facescatastrophic climate changeif it does wean quickly itself from its dependence on coal, oil and other fossil fuels for economic gr...
Hydrogen is a promising energy carrier and feedstock alike for decarbonizing the energy, transport, and chemical sector and mitigating the effects of global warming. Identifying and realizing environmentally friendly hydrogen production pathways is, however, significantly impeded by the need for step-wis...
Hydrogen from these technologies is often associated with the respective colors grey, blue, turquoise, and green. The critical comparison of the technologies is objectified and quantified based on the methodology of life cycle assessment. For this purpose, the environmental impacts of the hydrogen ...
Even producing green hydrogen to displace current grey H2“is a worse use case” for renewable electricity, Liebreich added. In his speech, the analyst also declared that green hydrogen will require subsidies for a long time to come, and that the EU will not be able to reach its renewable ...
The blue hydrogen vs green hydrogen debate Blue hydrogeninvolves producing H2 for fuel using processes powered by natural gas. This produces greenhouse gas emissions which, when released into the atmosphere, labels the H2 as grey. What makes it blue is the same production process followed by carbo...
To cut carbon dioxide emissions, hydrogen production must shift from its current reliance on fossil fuels. The most common method yields“grey hydrogen”,made from natural gas but without emissions capture. “Blue hydrogen,” which is also made from natural gas but with the associated carbon emiss...
