While hydrogen fuel offers numerous advantages, there are also challenges and limitations which need to be considered.  One of the main challenges is the limited infrastructure for hydrogen refueling stations. Unlike traditional fuel stations, hydrogen refueling stations are still relatively scarce. The limited infrastructure can pose logistical challenges for commercial vehicle manufacturers and fleet operators, especially when planning long-haul routes or operating in areas with limited hydrogen infrastructure.  Another limitation is the high initial cost of hydrogen fuel cell vehicles. Currently, the production and deployment of hydrogen fuel cell vehicles are more expensive when compared to traditional internal combustion engine vehicles or even battery EVs. However, as technology continues growing, the cost is expected to decrease over time.  Despite these challenges, commercial vehicle manufacturers are actively working towards addressing them and investing in the development of hydrogen refueling infrastructure to support the growing demand for hydrogen fuel-powered vehicles.
