Lengthy-haul trucking sits on the heart of the trade’s decarbonization problem. A number of powertrain choices are actually technically viable, however their operational match varies extensively relying on responsibility cycle, route construction, fueling entry, and fleet economics. The consequence for a lot of fleets is uncertainty reasonably than readability.
NACFE has taken a intentionally empirical method to this downside by grounding evaluation in real-world fleet operations reasonably than fashions or projections. Its latest long-haul analysis centered on Class 8 sleeper and day cab vans working beneath return-to-base and over-the-road situations, capturing how totally different powertrain applied sciences carry out in stay business service.
The work examined 4 propulsion classes: diesel and renewable diesel, pure gasoline and renewable pure gasoline, battery electrical, and hydrogen gas cell. Taking part automobiles have been already deployed in income service and instrumented with standardized telematics, permitting NACFE to check efficiency utilizing constant metrics whereas preserving operational context. This mix of quantitative information and qualitative fleet perception is central to NACFE’s method.
Fleet choice additionally mattered. NACFE evaluated a broad pool of candidates and narrowed participation primarily based on sensible standards, together with vans in energetic operation, willingness to share information transparently, and openness to on-site engagement. The ensuing combine averted expertise advocacy in favor of illustration throughout powertrains, geographies, and working fashions.
Somewhat than positioning one resolution as dominant, the findings spotlight tradeoffs. Diesel and renewable diesel proceed to supply operational familiarity and infrastructure depth. Pure gasoline reveals strengths in particular long-haul patterns the place fueling entry is effectively established. Battery electrical and hydrogen gas cell platforms reveal promise, however with constraints that stay extremely depending on route design, dwell time, and supporting infrastructure.
By anchoring evaluation in fleet information, NACFE shifts the long-haul powertrain dialog away from assumptions and towards operational match. For fleet operators, OEMs, and policymakers, the worth lies not in definitive solutions, however in a clearer understanding of the place every expertise performs effectively right now and the place additional growth or infrastructure funding remains to be required.
