Hydrogen Power Cleans Up Transit in China

China is ramping up investments in renewable energy in a concerted effort to combat pervasive air pollution problems. Evidence of this is the recent introduction in eastern Shandong Province of the world's first hydrogen-powered tram. The three-car tram accommodates 380 passengers and attains a speed of 70 km/hour (43 mph) for 100 km (62 miles). Hydrogen refueling requires only three minutes, and the only substance emitted is water. A mere 83 km of tram tracks exist nationwide, but a tenfold expansion in the tram network planned over five years should make this hydrogen fuel cell transit option more accessible.
