10 kV "double ring network + double radiation" power grid structure
The reliability of the comprehensive power grid has reached the international advanced level
As a bus driver
Zhang Yanru from gasoline cars, gas cars
To hydrogen fuel cell vehicles have been driven
"Unlike gasoline cars that need to be heated up in advance,
Nor is it like pure electric vehicles charging slowly,
High low temperature loss.
Hydrogen fuel cell vehicle refueling fast,
Low temperature start-up of -30°C can be achieved.
Vehicle operation is labor-saving and quiet,
It 'eats' hydrogen,
But water is discharged. ”
Zhang Yanru said

Hydrogen energy is a green, low-carbon and clean energy
Has a fast replenishment speed of energy
Features of less time
Compared to traditional fossil fuel vehicles
Hydrogen fuel cell vehicles
Every 100 km
Reduce CO2 emissions by about 70 kg
That's the equivalent of 14 average trees absorbing in a day
Compared with traditional fossil energy vehicles, hydrogen fuel cell vehicles can reduce carbon dioxide emissions by about 70 kilograms per 100 kilometers, which is equivalent to the absorption of 14 ordinary trees a day.

Conducive to post-match reuse
Follow the design
Only stay after the Winter Olympics
15,000 square meters of temporary construction
The rest will be torn down
They all return things to their original owners
Accept the next environmental "task"
Behind the green Olympic concept
It is China's great power
As the first commitment
A country that has achieved carbon neutrality in the Olympic Games
China will write history
