The Green Hydrogen Standard 2.0 will be launched by climate and energy leaders committed to move towards zero-emissions hydrogen by 2030. The next decade will see a huge increase in the use of green hydrogen and green hydrogen derivatives in major sectors like shipping, steelmaking and aviation. We need green hydrogen standards that define what renewable electricity can be used to produce green hydrogen and emissions thresholds aligned with our net zero ambitions. As regional and national standards are evolving, the global Green Hydrogen Standard is being updated to move towards full lifecycle analysis, address hydrogen leakage, and consider requirements for biomass as a source of energy for green hydrogen production.
