Kenworth developing hydrogen fuel cell, Near Zero NOx CNG series hybrid Class 8 prototypes for SoCal ports; CNG hybrids

Green Car Congress

Kenworth is developing a prototype Class 8 hydrogen fuel cell tractor, using the Ballard Power Systems fuel cell to recharge the battery pack. The truck will use the currently available Cummins Westport ISL G Near Zero NOx engine fueled by compressed natural gas (CNG) to generate electrical power.

How to make heavy-duty electric trucks work in practice

Charged EVs

The far higher volumes of carbon dioxide per mile from heavy trucks make them an obvious target for zero-emission powertrains. Some makers suggest hydrogen fuel cells will be the way to go; the most promising application seems to be long-haul trucking with few or no stops. But today, heavy trucks remain a diesel world.

Software Upgrade to Prius PHEV NiMH Conversion Kit Enables All-Electric Driving At Up to 70mph

Green Car Congress

kWh NiMH plug-in hybrid (PHEV) conversion kit that enables all-electric mode driving at speeds of up to 70 miles per hour (until the battery pack is depleted) in a converted Prius. What we’re essentially offering is all-electric performance for about 25 miles at highway speeds. Poway, California-based Plug In Conversions Corp.

Argonne Study Examines Impact of Real World Drive Cycles on Efficiency and Cost of Different PHEV Configurations

Green Car Congress

Aymeric Rousseau, program manager at Argonne, presented a small slice of this wide study at the Advanced Automotive Battery Conference 2009 (AABC) this week in Long Beach. These were compared to a conventional HEV, using the same hybrid drive as the power split PHEV, and a conventional combustion engine vehicle. L/100km (35.6

Clearing the roadblocks to electrification of heavy-duty trucks

Charged EVs

Unlike individual car owners, fleet operators know exactly how many miles their vehicles travel, and they aren’t likely to be swayed by questions of styling or coolness factors—if you can demonstrate that an EV will save them money, then you should be able to make a sale. Most commercial trucks are engineered for 1.2 million miles.

As the off-road vehicle market rushes to electrify, standards are lagging behind

Charged EVs

When engineers specify components that aren’t automotive-rated, they are then forced to spend time in extensive testing to make sure their vehicles don’t catch fire. And there’s 40% of the Class 8 market and the medium-duty market that [drives] under 250 miles a day. With current technology, they can hit those numbers.
