of the Chevrolet Equinox fuel cell vehicle in 2007. The HydroGen4 is
designed for a life cycle of two years/80,000 kilometers and can start and
run at sub-zero temperatures. It represents a considerable advancement
over the HydroGen3.
Hyundai introduced its new i-Blue Fuel Cell Electric Vehicle.
The i-Blue platform incorporates Hyundai's third-generation fuel cell
technology and is powered by a 100-kW electrical engine and fuel cell
stack. It is fueled with compressed hydrogen at 700 bar stored in a 115 liter
tank. The i-Blue is capable of running more than 600-km per refueling stop
and has a maximum speed of 165-km/h.
In 2010, Mercedes-Benz plans to launch the first series-production car
of the B-Class F-Cell vehicle. This F-Cell will contain the next generation
fuel cell engine with a redesigned stack that is 40 percent smaller and
produces 30 percent more power.
HYDROGEN BUS TECHNOLOGY
The Hydrogen Bus Technology Validation Program in Davis/
Sacramento, California is a multi-district partnership of the City of Davis,
Yolo County Transportation District (YCTD), University of California,
Davis (UC Davis), UniTrans (Transit authority for the City of Davis and
UC Davis), and NRG Tech.
The City of Davis receives the project funds for disbursement to the
other project partners. The program seeks to validate advanced clean fuel
technologies in a practical application.
Hydrogen fuel-based technologies hold great promise in reducing
carbon dioxide and toxic air emissions from mobile sources in meeting
current clean air standards and proposed greenhouse gas reductions.
The Hydrogen Bus Technology Validation Program will use the
hydrogen powered buses to provide service in the Davis/Sacramento
region. Some buses will operate on a blend of natural gas and hydrogen
using advanced internal combustion engines with technology developed
for NASA. Others will be Proton Exchange Membrane (PEM) fuel cell buses
and operate on compressed hydrogen. All the buses will be 40-foot transit
buses. After a testing period, UniTrans and YCTD will run the buses along
standard transit routes. The buses will refuel at the modified UniTrans
depot, which will support compressed hydrogen and hydrogen/natural
gas fueling.
