This scene is representative of the broader situation in Nanhai district, where only about half of the over 380 hydrogen buses remain operational. Officials from the Foshan municipal government revealed that other districts within the city have also halted hydrogen bus services. These include lower-than-anticipated demand for public transit, financial constraints limiting government subsidies, the high initial purchase price of hydrogen buses, and persistently high hydrogen fuel prices. Most of Foshan’s hydrogen buses, approximately 1,000 units, were procured between 2018 and 2019, with no new purchases made since 2021. Despite subsidies, hydrogen buses were significantly more expensive than their electric counterparts.
