Recently, 10 hydrogen buses developed by the Ningbo Green Power Hydrogen Technology Research Institute debuted at the Boao Forum for Asia Annual Conference 2021. The buses covered a combined mileage of 20,000 kilometers shuttling Forum participants, attracting much attention.
These hydrogen buses were independently developed by the State Power Investment Corporation Hydrogen Energy Company. State Power Investment's subsidiaries, Ningbo Green Power Hydrogen Technology Research Institute and Ningbo Green Power Fuel Cell Co., Ltd., participated in the development and production.
The main duties of the hydrogen buses at Boao include airport transfer, shuttling for exclusive events, and emergency standby. Each vehicle, 11 meters long and seating 45 passengers, is equipped with a fuel cell system independently developed by State Power Investment. It takes about 20 minutes to fill up with hydrogen and has a range of up to 650 kilometers.
The bus emits 70 kg less carbon dioxide every 100 km than a regular bus, which is equivalent to the amount of carbon dioxide absorbed by roughly 14 ordinary trees during one day, or the amount exhaled by an adult in about 50 days.
Engineers from Ningbo Green Power Hydrogen Technology Research Institute were stationed at Boao to provide regular maintenance for the buses. They have been working continuously for more than a month.
"In Boao, Hainan, the outdoor temperature is normally above 30°C and the air humidity is high. Sometimes, we have to discharge cooling water and replace meters under the scorching sun. Once, one of my colleagues had a heat stroke during the task," said an engineer from Ningbo Green Power Hydrogen Technology Research Institute. "But when the hydrogen bus drivers told us that the hydrogen car was efficient, quiet, and comfortable to drive, we felt that it has all been worthwhile."
Hydrogen buses will be officially put into operation in Ningbo before September this year; the prototype is in the final testing and commissioning stage. The first 20 hydrogen energy buses will be manufactured in the first half of this year. Compared with lithium battery vehicles, hydrogen energy battery vehicles are more environmentally-friendly, achieving zero emissions and zero pollution.
