Ordos Ejin Horo International Airport in Inner Mongolia switched on a CO2 based heating and cooling system in March 2025. It runs on wind and solar power, covering more than 90% of the airport's energy use and cutting annual carbon emissions by about 9,500 tonnes. The system also eliminates fluorocarbon refrigerants and cooling water demand.

Good to see a concrete airport project instead of another MoU. The 21 million kWh and 9,500 tonnes of CO2 are actual numbers. Would like to know the capex and payback. Article only mentions operating costs down 50%, which is not the full financial picture.
The CO2 based system is interesting. Since it eliminates fluorocarbon refrigerants, the 9,500 tonne reduction likely includes avoided refrigerant GWP, not just combustion. That matters when comparing this to other airport retrofits. Also, 2 million cubic metres of natural gas saved is a solid number.
Wind and solar at an airport need firming. The hydrogen storage part is still a proposal. Curious how the airport handles days with low renewable output. Is the 21 million kWh generated on site or purchased from the grid? The article does not say.
This is the kind of pilot that gets replicated if the economics hold. The 800 million yuan programme for data centres, mines, transport, and desert is a signal. For Pakistan, the key is whether the tech transfers without the same subsidies and grid conditions.
The 60% drop in heating and cooling energy consumption is the real story. Airports are huge energy hogs. CO2 heat pumps are proven but rarely used at this scale. The 50% operating cost cut will get facility managers attention.
Good example of a coal-heavy region moving to clean energy. The airport project is small compared to Ordos coal output, but it shows a pathway. Would be useful to see how the hydrogen storage pilot performs before scaling it to industrial parks.
