World Hydrogen Day is celebrated to raise awareness of hydrogen's role in transitioning to a low-carbon economy. While hydrogen is already used in industries like oil refining, the majority is produced using CO2-intensive methods. Clean hydrogen, produced through carbon capture or electrolysis, has the potential to decarbonize industries and offer fuel alternatives. Scotland supports clean hydrogen in its planning system, particularly green hydrogen production. However, challenges remain in integrating green hydrogen into renewable energy projects due to separate planning processes. Scotland's National Planning Framework expresses support for hydrogen development, but implementation at individual planning levels is pending. Streamlining the consenting process for hydrogen projects connected to renewable energy sources is crucial for achieving net zero emissions.
