Technology

Hydrogen Fuel cell Tram is a hydrogen electric tram that uses hydrogen to generate electricity. Its power source is electricity generated by a fuel cell, which supplies oxygen from the air to the hydrogen stored in the vehicle's rooftop hydrogen tank. It can travel over 200 km on a single charge and does not require external power supply facilities, such as large-scale power supply and substation facilities. It is constructed entirely without cables, eliminating the need for power lines within the city. Furthermore, it can be operated simply by laying tracks, allowing for flexible, cost-effective expansion of the route in the future.^[1]

It does not emit pollutants, so they effectively purify fine dust and improve air quality during operation. The 34 trains used on Daejeon Metro Line 2, operating for 19 hours, produce enough clean air to consume approximately 110,000 people in one hour.^[2]

Operations

In July 2024, Daejeon ordered 34 trains for Daejeon Metro Line 2. Operation is scheduled to start in 2028.^[3]
