Energy Storage for Fuel Cell & Hybrid Electric Buses: Nickel Hydrogen Battery

The objective of this project is to design and develop a compact, lightweight and reliable energy storage for hybrid electric and fuel cell transit buses. The effort includes the development, demonstration and evaluation of the application of an innovative, segmented nickel-hydrogen battery to hybrid electric transit buses. This project will demonstrate and evaluate the commercial viability of a technology that was initially developed under a Defense Advanced Research Projects Agency program and further refined under the Department's Advanced Vehicle Program. The technology includes a hydrogen storage unit separate from the electrochemical reaction that permits hydrogen to be stored in a solid state, bonded to a metal alloy. The hydrogen is drawn upon when needed (applying an electrical load to the battery) and is returned to the storage unit when the battery is charged from the engine generation of electricity or from electricity provided by regenerative braking. The separate storage avoids hydrid breakdown that shortens the life of the nickel metal hydride batteries. Unlike other fuel cell products, the ElectraStor System does not require a renewable source of hydrogen or the storage of gaseous or liquid hydrogen that necessitates a potentially dangerous large on board supply of hydrogen. All of the hydrogen needed for the life of the ElectraStor products is contained safely within the metal alloy included within the separate ElectraStor storage unit.
