Green hydrogen drive could backfire without supply chain overhaul, study says

Green hydrogen—the cornerstone of net zero strategies around the world—could fail in becoming a truly sustainable fuel unless countries rapidly decarbonize their energy grids, according to research led by the University of Sheffield. In a study published in the journal Communications Sustainability, researchers have highlighted the decisive role that national energy mixes will play in determining the level of emissions involved in producing the fuel and its impact on the environment.
