A new tool boosts the aim of providing a consistent accounting framework for measurement and tracking of the carbon emissions associated with hydrogen production.
Governments and environmental agencies worldwide have aligned on three principles for green hydrogen production:
-
Additionality: Green hydrogen must be generated from new renewable projects to avoid using existing clean electricity facilities. This ensures hydrogen production contributes to the overall goal of decarbonisation.
-
Geographical correlation: The renewable energy used for hydrogen production should be sourced from within the same region. This principle emphasises the importance of aligning the location of renewable energy generation with the site of hydrogen production.
-
Time matching: Hydrogen producers must demonstrate that their electrolysers are consistently powered by 100% renewable energy. Annual time matching requires only that sufficient renewable energy has been sourced over a year. Hourly time matching ensures renewable energy is sourced only when the wind is blowing, or the sun is shining.
