Yes, hydrogen buses are designed with safety in mind. The hydrogen tanks are built to withstand severe impacts, and there are multiple sensors and safety systems in place to detect and manage leaks or other potential issues.

The ticket prices for riding a hydrogen bus are generally comparable to those of traditional buses. While the operational costs for hydrogen fuel can be higher, many service providers work to keep fares affordable for passengers.

The frequency at which a hydrogen bus needs to refuel depends on several factors. On average, hydrogen buses can travel approximately 300 to 400 kilometers (about 186 to 250 miles) on a full tank of hydrogen. This means that under typical urban operating conditions, a hydrogen bus might need to refuel every day or every other day.
