Hydrogen fuel-cell buses have begun operation in Zhengzhou, Henan province in China.
The country’s first two hydrogen fuel cell buses started operation in the city on Wednesday.
The number of such buses will reach 10 by end-October.
Hydrogen consumption of the bus is less than 7.2 kilograms per 100 kilometers, while the driving range can reach more than 500 kilometers
The engines emit water that is clean enough to drink, instead of carbon dioxide – a greenhouse gas. It takes 3 to 5 minutes to refuel each bus, and they can travel for about 500 kilometres on a full tank.

According to Wikipedia, a fuel cell bus is a bus that uses a hydrogenfuel cell as its power source for electrically driven wheels, sometimes augmented in a hybrid fashion with batteries or a supercapacitor.
Several companies are conducting hydrogen fuel cell research and practical fuel cell bus trials. These include:
Daimler AG, with thirty-six experimental units powered by Ballard Power Systems fuel cells completing a successful three-year trial, in eleven cities, in January 2007.
Thor Industries (the largest maker of buses in the U.S.), based on UTC Power fuel cell technolog.
2 new H2 refueling stations⛽️ are coming to Rhineland Germany!
Both stations can supply up to 20 environmentally-friendly H2 buses with a total of 500kg of H2 on a daily basis👏https://t.co/BsSFYn9XIR#FutureOfTransport #hydrogen #mobility #CleanEnergy pic.twitter.com/4AW3CIBsnd
