The hype around using green or blue hydrogen as a decarbonization tool overlooks the fact that all hydrogen use can significantly increase global warming. How hydrogen is produced can have significant climate impacts. The push behind blue and green hydrogen as “clean” alternatives to grey hydrogen, which is produced using fossil fuels, overlooks the fact that both blue and green hydrogen production can generate even more greenhouse gas emissions than grey hydrogen. This two-page fact sheet outlines the potential harms and global warming impacts from blue and green hydrogen.
