The report by Cambridge Econometrics and the University of Exeter delves into the potential of green hydrogen as a cost-competitive alternative to grey hydrogen in industries globally. Currently, most hydrogen production generates carbon dioxide, contributing to climate change. The study suggests that targeted policies like global mandates on green hydrogen usage and carbon pricing could drive the competitiveness of green hydrogen. Dr. Femke Nijsse highlights that while green hydrogen may not entirely live up to the hype, it stands as a crucial option for decarbonizing fertilizer production and clean steel making. The research underscores the necessity of sustained policy support to reach a 'tipping point' for cost-competitive green hydrogen. Furthermore, the report underscores the regional disparities, as seen in Brazil's potential to leverage its wind power for cost-competitive green hydrogen production. By implementing appropriate policies, Brazil could reduce import dependency and even become a regional exporter of low-carbon hydrogen products. The study emphasizes that even regions with abundant renewables face challenges like demand-supply imbalances without proper policy frameworks. Funded by the UK Government, the research aims to foster green hydrogen adoption for emissions reduction and transition towards renewable energy sources.
