Since its inception on 7 July 2021, and with the support of the Government of China and the United Nations Industrial Development Organization (UNIDO), the International Hydrogen Energy Centre (IHEC) has been promoting the development of hydrogen energy, including through the world’s largest demonstration project – jointly led by IHEC and Beijing Sinohytec – of hydrogen fuel cell commercial vehicles during the 2022 Beijing Winter Olympics as more than 850 hydrogen fuel cell buses were used to transport athletes and officials with 9 green hydrogen refueling stations built in Zhangjiakou, Hebei Province. In total, the buses operated over 3.2 million kilometers and consumed around 200 tons of green hydrogen, which saved an estimated 2,000 tons of carbon.
