impact us and our customers,” said Chad Conley, vice president, vocational truck at Navistar Inc.“ While the goal is to reduce emissions from commercial trucks, CARB( California Air Resources Board) and EPA are approaching greenhouse gas emissions goals in different ways.”
Conley explained the approaches to addressing emissions( NOx) and greenhouse gas( CO2):
● EPA’ s clean trucks plan and greenhouse gas standards mandate an end result by limiting the average emissions that vehicles sold by a manufacturer can produce annually.
● CARB clean truck check, advanced clean trucks and advanced clean fleets programs mandate the percentage of sales or the fleet that need to be zero-emission vehicles.
Conley also noted that full or partial CARB standards have also been adopted by 16 states, the District of
Columbia and two provinces. Navistar’ s expectation, however, is that EPA GHG Phase 3 standards will be in place across the country and that Canada is expected to adopt them as well.
Developing Targeted Technologies
Different perspectives are required to develop target technologies, related Michael Young, product marketing manager for Detroit Engines at Daimler Truck North America.“ Different solutions are driven by customer needs so our zero-emission vehicle portfolio will cover three different technologies, including battery electric vehicles( BEVs), hydrogen fuel cell electric and hydrogen internal combustion engines,” he said.“ We believe this dual strategy of electric and hydrogen vehicles is the right answer.”
Daimler Truck also continues investing in clean diesel, Young noted.“ Zero-emission technology is moving fast, however the well-known hurdles of infrastructure and range capabilities will keep a large portion of the industry powered by internal combustion engines for the coming years,” he stated.“ Major vocational segments must be supported with diesel solutions.”
Young added that technical, customer and infrastructure needs must be met.“ Success toward zero emissions hinges on the whole system performing,” he said.“ Without all elements in place the market will not be ready.”
Focusing on a Range of Solutions At Peterbilt Motors Company, according to Mitesh Naik, director of product planning and strategy, regulatory compliance is focused on a range of solutions. Included are clean diesel and hydrogen internal combustion engines; hybrid, battery electric and fuel cell electric vehicles, and specification changes and credits.
Next generation medium-duty battery electric vehicles from the company will have a 150- to 200-mile range and a fast DC charging time of one to
