ISE and Crane Carrier Company will build series hybrid trash trucks
If there is any type of vehicle that would seem ideally suited to a hybrid drive application, it is a garbage truck (right, Volvo?). With the continuous stop and go driving involved with collecting the detritus of modern civilization there is plenty of opportunity for regenerative braking and electric launch. ISE Corporation already has a series hybrid system that they've developed for transit bus applications. ISE is partnering with Crane Carrier Company to build five series hybrid trash haulers for testing in New York, Chicago and Houston. The project is being organized by the Hybrid Truck Users Forum of CALSTART. ISE's ThunderVolt system is a self-contained hybrid drive system designed for installation into existing vehicle platforms. A pair of motor-generators are mated with a combining gearbox and replace the conventional transmission unit in buses and trucks. Electrical energy storage will be handled by either nickel metal hydride batteries or ultra-capacitors.

Series hydraulic systems may be better for large stop/start applications like trash trucks and city buses. As mass increases tanks become more efficient than batteries for regen energy storage. I'm not sure where the tipping point is, but I'd bet that it is around 20K/lbs gross vehicle weight. Ultracapacitors with electric helper motors may be an even better solution until the cost of the new batteries decreases.
