SOLUTIONS * USA - 1· Big-Rig Hybrids
People usually do not associate the word "green" with diesel trucks, but big diesels are getting cleaner
New York,NY,USA -Forbes, by Deborah Orr -19 Mar 2008: -- ... All new heavy-duty diesel engines sold in the U.S. after 2007 must meet strict new Environmental Protection Agency (EPA) standards that filter almost all the black soot particles and much of the nitrogen oxides that cause acid rain. The next set of standards, set to go into effect in 2010, will reduce nitrogen oxides even further... The dirty little secret of the cleaner diesel engines: they burn more fuel--a big problem for fleet operators facing a 44% rise in diesel fuel costs over the last year. Commercial vehicles--the main consumers of diesel fuel--can accumulate 75,000 miles in a year... Even a small decrease in fuel efficiency can make a big difference to truck operators' bottom lines... This is why heavy-duty truck manufacturers are now paying a lot of attention to diesel hybrids... A hybrid truck can deliver fuel savings of 5% to 60%, depending on how it is driven. For one type of hybrid technology, the EPA estimates the average urban delivery truck could save more than 1,000 gallons of diesel fuel per year... Hybrid power systems work best in vehicles that stop and start all the time, which means that they are ideal for delivery trucks, garbage trucks and school and city busses. For a long-haul vehicle, the savings would be significantly less... One way hybrids save energy is by using an electric motor, or even a pressurized hydraulic system, to boost the performance of the internal combustion engine when the vehicle is accelerating or under heavy load. The energy can be stored chemically (in a battery), electrically (in a capacitor) or mechanically (in a pressurized hydraulic system)... The Energy Policy Act of 2005 can provide federal tax credits of up to $12,000 per unit for diesel hybrid purchases... That may not be quite enough to offset an initial 35% premium over conventional vehicles, but with diesel averaging $3.88 a gallon nationwide, fleet operators will be weighing their options: pay more up front at the dealer or pay more at the pump for years to come...
