Strong commitment and action from traditional diesel truck manufacturers to launch electric trucks is pointing to a promising move towards heavy-duty electrification. While heavy-duty electric trucks account for only 2.7% of all US trucks, they amount to almost 22% of fuel use from the trucking sector and 7% of total road transport emissions. However, heavy-duty trucking has been traditionally considered to be the most difficult to electrify due to its long-haul nature. How many heavy trucks actually travel long-haul vs. short-haul? How many vehicles can be electrified based on the range available in today’s trucks? What does that mean for % VMT electrified and oil displacement? In this insight, we answer these questions and discuss our outlook for US heavy-duty truck electrification, as well as the upside potential.
