ST-1.1 Energy-Efficient Vehicles

From March 2006 through mid-2010, AC Transit operated three fuel cell buses, logging over 270,000 miles and carrying over 700,000 passengers, all while achieving significantly greater overall energy efficiency than diesel buses.

Now, AC Transit is taking delivery of twelve, new, third-generation fuel cell buses. The new buses feature a redesigned chassis that is 5,000 pounds lighter than the earlier  buses. Each new bus is powered by a 120 kW fuel cell power system, built by UTC Power of Connecticut, and an advanced lithium ion energy storage system by Enerdel of Indiana.

Hydrogen tanks on the roof give the bus a range of 354 to 386 km (220 to 240 miles), and batteries recharged during braking can provide extra power for acceleration and climbing steep grades.
