The suspension of Foshan’s hydrogen tram service after four and a half years reflects the challenges of implementing hydrogen technology on a large scale. Despite hydrogen’s promise as a clean energy source, issues such as high production costs, low ridership, and the need for robust public education and economic models have highlighted the complexities of transitioning to hydrogen-powered transportation. While this pause may seem like a setback, it offers valuable lessons for future green energy projects, emphasizing the need for a holistic approach that considers technological, economic, environmental, and social factors.
