 NREL researchers partner with DOE and industry to develop next generation advanced heavy hybrid propulsion technologies and systems. These technologies and systems are projected to increase the fuel efficiency of heavy trucks (Class 3-8) and buses by as much as 100%, and improve their emissions to meet the Environmental Protection Agency's 2007-2010 emission standards.
"Hybrid technology has already demonstrated it can dramatically increase the fuel economy of cars," DOE Secretary Abraham said. "Our goal through this important AHHPS project is to achieve the same economic and environmental benefits for heavy commercial vehicles. In the process we also make our nation more secure by reducing our dependence on foreign sources of oil."

An objective for the hybrid powertrain technology is to develop and validate cost-effective, advanced next-generation heavy hybrid components and systems, which at the vehicle level could provide, contribute to, or enable a powertrain efficiency increase as high as 100% relative to today's conventional powertrain technology.
The AH2PS team also works to identify heavy hybrid vehicle system requirements using technical target setting, which will help industry meet the goals of the AH2PS project—to double the fuel economy for commercially viable vehicles. NREL researchers use the technical target setting process to find solutions that have the lowest associated R&D effort and life cycle cost.
