National Petroleum Council Report: "Diesel Engines Will Remain the Powertrain of Choice for Heavy Duty Vehicles For Decades to Come Because of Their Power and Efficiency."

The report – "Advancing Technology for America's Transportation Future" – was authored by the National Petroleum Council (NPC) at the request of the Energy Secretary Stephen Chu.  The two-year study examines fuels, technologies, industry practices, and government policies through 2030 for auto, truck, air, rail, and waterborne transport and potential industry and government actions that could reduce

Greenhouse gas (GHG) emissions from American transportation by 50 percent by 2050.

"The National Petroleum Council findings confirm what transportation officials and industry leaders have already determined – that the continued advancements in clean diesel technology will continue to make diesel the dominant power source for heavy-duty trucks throughout the United States for decades to come," said Allen Schaeffer, the Executive Director of the Diesel Technology Forum (DTF).

The NPC report states: "Diesel engines will remain the powertrain of choice for HD vehicles for decades to come because of their power and efficiency. There are, however, opportunities to improve the technology. Significant fuel economy improvements in diesel powered trucks are possible. Indeed, the fuel economy (mpg) for new Class 7&8 HD vehicles, which consume more than 70% of the fuel in the trucking fleet, could be doubled."

As The New York Times reported: "(A)t a briefing by the council, one member, William Reinert, the national manager in charge of the advanced technology group for Toyota's American sales unit, put it bluntly. 'Internal combustion engines are likely to be the dominant propulsion system for decades to come,' he said. Hybrids like his company's Prius and vehicles running on natural gas, diesel or cellulosic biofuels have internal combustion engines at their heart, he pointed out."

Over 80% of Freight in U.S. is Moved By Diesel Power
"Today, diesel powers more than 80 percent of freight movement in the U.S. and internationally more than 90 percent of global trade is moved by diesel engines," Schaeffer said.

"There is a reason today that diesel powers the overwhelming majority of the nation's commercial trucking, school and transit bus fleets," Schaeffer said. "Diesel's unmatched combination of availability, safety, energy-efficiency and economical operation and performance has made it the technology of choice, but it is also the environmental performance and prospects for even greater energy efficiency that make it the technology of choice for the future.

"The advances in diesel technology have improved efficiency and significantly reduced emission to the point that diesel engines are now near zero emissions. The NPC report also highlights that diesel technology will continue to advance in the coming years.  These are all reasons why the National Petroleum Council and transportation officials' project diesel will be the primary power behind freight transportation for many decades to come.  Diesel's role as a technology to increasingly power light-duty vehicles in the future was also recognized in the report."

Tens of Billions of Dollars and Decades Needed To Provide Alternative Fuel Infrastructure
The NPC report examined several alternative fuel sources including natural gas, which NPC said could make inroads into heavy-duty trucking "assuming that the current price spread between diesel and natural gas persists over time."

The report also highlighted the major infrastructure problems natural gas and other alternative fuel sources face.  "Deployment of a new fuel infrastructure is a significant hurdle to the adoption of new fuel-vehicle systems. It could cost tens to hundreds of billions of dollars to provide similar alternative fuel availability as the current gasoline infrastructure and will take decades to fully deploy.  Some fuels also require advances in supply-chain infrastructure technology to aid deployment. Specifically, advanced biofuels must overcome technology hurdles related to fuel manufacturing, and hydrogen must overcome technology hurdles related to dispensing infrastructure."

Less Than 10% of Freight Carriers Feel LNG Will Be Widely Adopted By Trucking Industry
The NPC study also coincides with a recent survey of industrial freight carriers which found less than 10 percent of senior executives currently "believe LNG will be widely adopted of over-the-road trucking."  The survey also found that while freight carriers were generally aware of LNG-powered vehicles, 72% felt that the technology had limited adoption potential for industrial freight.

"Government Policies Should Be Technology Neutral" Report Recommends
"The NPC report also recommended against having the government attempt to pick winners and loser in transportation," Schaeffer said.

The report stated: "There is a great deal of uncertainty regarding which individual fuel-vehicle systems will overcome technology hurdles to become economically and environmentally attractive by 2050. Therefore, government policies should be technology neutral while market dynamics drive commercialization."

"The NPC recommendation urging technology neutrality is one the Administration should heed, particularly given past experience favoring certain energy sources and technologies," Schaeffer said. 

ABOUT THE DIESEL TECHNOLOGY FORUM
The Diesel Technology Forum is a non-profit national organization dedicated to raising awareness about the importance of diesel engines, fuel and technology. Forum members are leaders in clean diesel technology and represent the three key elements of the modern clean-diesel system: advanced engines, vehicles and equipment, cleaner diesel fuel and emissions-control systems.
