Ordos city in North China's Inner Mongolia autonomous region is making full use of its natural resources and geographical conditions to develop renewable forms of energy. 

The city is located between 37 and 40 degrees north latitude. It receives annual solar radiation of 5,600 to 6,000 megajoules per square meter, and Ordos’ annual average hours of sunshine can reach 3,100 hours.

Meanwhile, the city's Otog Banner, Otog Front Banner and Hanggin Banner are located in the narrow and long air outlet zone between Langshan and Yinshan mountains. 

They are the main channels for cold air flowing south from Siberia, making them ideally suited for wind power production. 

For the city's coal mining subsidence areas, reclamation areas and mining dumps, they have the advantage of being able to build large-scale photovoltaic power generation bases and large-scale wind power bases able to generate tens of millions of kilowatts.

By the end of 2020, the total installed capacity of new energy in Ordos city reached 3.13 million kilowatts, including 1.91 million kWh of photovoltaic power generation, 400,000 kWh of wind power, 760,000 kWh of hydropower, and 60,000 kWh of biomass.

Additionally, Ordos is projected to replace traditional heavy trucks with trucks powered by hydrogen energy. And the city's Ejin Horoo Banner is planning to develop full industrial chains featuring hydrogen energy.

"Ordos is rich in wind energy and water resources, has low hydrogen production costs, and has a wide range of application scenarios. It is very suitable for the development of the hydrogen energy industry," said Xu Jiangang, director of the development and reform commission of Ejin Horoo Banner.

Ordos now decommissions approximately 75,000 heavy trucks every year. Replacing each one with a hydrogen-powered heavy truck is estimated to reduce carbon dioxide emissions by 110 tons. 

That year, the city can directly reduce carbon dioxide emissions by 8.25 million tons and save nearly one-third of fuel costs per kilometer.

The first batch of pilot hydrogen vehicles in Ejin Horoo has now been rolled out, and it is expected that demonstration operations will begin after the completion of a hydrogen refueling station this year.
