Despite dominance of diesel, trucks to evolve towards electrification

Commercial vehicles will continue to run on diesel fuel for the foreseeable future, according to new research from analyst firm Markit.

Sixty-six percent of new medium and heavy commercial vehicles sold in the US will be fueled by diesel (diesel and diesel hybrid) in 2040, compared to nearly 80 percent today.

The study was completed between January and July of 2018.

Diesel is expected to remain the dominant fuel type globally through 2040 due to increases in fuel economy which will play a major role in keeping diesel competitive versus alternative powertrains, the study says.

Range and load capacity requirements from long-haul, on-highway trucking will keep diesel relevant in the short- and long-term, while other propulsion types will grow in popularity as technology continues to advance.

?Understanding the future course of commercial trucking is so important because its impacts will reverberate far beyond just the trucking industry and through a whole host of industries,? said Daniel Evans, vice president of the IHS Markit downstream practice and co-author of the study. ?Trucking accounts for half of diesel demand globally, or one-sixth of oil demand, making the future of trucking critically important for the oil industry. A holistic, system-wide view is needed to see the full picture of this new reality of transportation.?

While diesel does remain dominant, the report and forecast indicate a 15 percent compound annual growth rate (CAGR) for battery electric vehicles in the US during the timeframe, as adoption rates increase in medium-duty trucks.

This growth is driven from an increase in urban trucking ton-km and advancements in battery technology allowing for more mainstream adoption ? particularly among class 4 and 5 trucks with lighter payloads.

The study also highlighted a view on total cost of ownership (TCO), with modeling suggesting BEV struggles in competitiveness compared to diesel and natural gas (CNG and LNG).

Additionally, the weight requirements of the battery pack cause limitations on the hauling capacity of the truck. Currently, to achieve equivalent range compared to a diesel class-8 truck, the subsequent battery pack weight required would result in a large cargo capacity penalty.

Due to the initial cost disadvantage of these alternative powertrains, larger truck fleets will be the first to adopt alternative powertrain technologies. Smaller fleets and owner-operators encompass a large share of the market, leading to the slower adoption curve seen in the study.

Also, larger fleets will have the capacity to implement a diversified fleet in a more strategic manner, allowing for alternative propulsion options to be implemented in areas that maximize their fuel saving benefits and minimize the range and payload penalty.

?The regulatory environment will have a large impact on the pace of change in the industry between now and 2040,? said Matt Trentacosta, automotive advisory consultant for IHS Markit and a co-author of the study.

?A diesel ban within city centers has the potential to cause fleet owners to adjust their strategy alongside OEMs and suppliers,? he said. ?In addition, trucking impacts energy consumption and any dramatic change could elicit a major disruption in the energy markets.?
