Seoul says it will supply more than 4,000 hydrogen cars by 2022.

The city said, "We plan to aggressively supply 1,000 units by adding 1,000 units to the 3,000 units announced in October last year."

Park Won Soon's exclusive car was also changed to hydrogen car.

Electric cars used as existing cars will be converted to general business vehicles in Seoul and used by employees.

Mayor Park will ride the hydrogen car at the '2019 World Cities Forum for Climate Change' held at COEX on the first day of using hydrogen car.

The city explained that the city is willing to expand its hydrogen car to cities around the world.

Seoul City supplied 591 hydrogen cars last year.

Next year, 1,854 units will be distributed.

Hydrogen stations are now increasing from four to ten next year.

Seoul's hope is that if the supply of hydrogen cars expands, the demand for hydrogen cars will be largely resolved.

In Seoul, there are more buyers than other cities and provinces, so you have to wait at least one year to buy a hydrogen car.

The city plans to establish a mid-to-long term strategy for building a 2030 hydrogen fueling station as soon as the results of the service for expanding the hydrogen car charging infrastructure are available.

Hydrogen cars produce electricity by combining hydrogen with oxygen in a vehicle's electricity generator (stack).

Although it is regarded as an eco-friendly vehicle that emits only water and air, it lacks infrastructure such as a charging station than electric vehicles, and high price and charging costs are considered disadvantages.

Park said, “In order to actively respond to the climate crisis, use of eco-friendly cars is a necessity, not an option. Said.
