Green hydrogen has long been hailed as a key solution for decarbonizing heavy industries and transportation. Produced by splitting water molecules using renewable electricity, it offers a clean alternative to fossil fuels. However, recent research from Harvard University indicates that the costs associated with green hydrogen are significantly higher than previously projected. The study highlights that, when accounting for storage and distribution expenses, green hydrogen can be prohibitively expensive, often exceeding the costs of directly removing CO₂ from the atmosphere. belfercenter.org
This revelation underscores the need for substantial technological advancements and policy support to make green hydrogen a viable option for large-scale decarbonization. While the potential remains, addressing these economic challenges is crucial for integrating green hydrogen into the global energy mix.
