The new report sheds light on the challenges and opportunities in kickstarting 'green hydrogen' production to decarbonise the global economy. Currently, most hydrogen is produced as 'grey hydrogen' from natural gas, contributing to climate change. Green hydrogen, produced by splitting water using renewable energy, offers a carbon-free alternative. The report by Cambridge Econometrics and the University of Exeter explores the role of targeted government policies in fostering a cost-competitive green hydrogen industry globally. While green hydrogen has the potential to revolutionize sectors like fertiliser production and clean steel manufacturing, achieving cost competitiveness requires strong and sustained policy support. The report emphasizes the importance of policies like global mandates for green hydrogen usage and carbon pricing on hydrogen production. It also highlights regional disparities, showcasing countries like Brazil that can become leaders in green hydrogen production with adequate policy support. The University of Exeter's upcoming Climate Forum will further engage stakeholders to address the climate emergency and discuss actionable steps towards a sustainable future.
