Analysis: Electric Heavy-Duty Vehicle Powertrains Can Provide Lower Total Cost of Ownership

For commercial medium- and major-duty electric motor vehicles, the adoption of a new know-how relies closely on its price tag relative to alternatives. A new report from the National Renewable Strength Laboratory (NREL) seeks to pinpoint the conditions for when battery electric powered or fuel cell electric powered commercial trucks offer you economic advantages around traditional diesel-fueled trucks by analyzing a essential metric — the full cost of ownership (TCO).

For many years, medium- and heavy-obligation vehicles have presented exceptional worries to decarbonization of the transportation sector. For one, these motor vehicles must face up to noticeably additional annual use than a personalized automobile. On typical, commercial Course 8 tractors can anticipate to travel 120,000 miles each and every yr. In addition, business autos are exceptionally major, ranging from 14,000-pound Course 4 delivery automobiles to Course 8 tractors hauling up to 80,000 pounds. Altogether, medium- and significant-duty trucks account for 26% of nationwide fuel use — irrespective of building up just 4% of the total vehicle population — and greenhouse gasoline emissions from medium- and weighty-duty vehicles continue on to maximize at a amount quicker than emissions from light-weight-duty autos in the United States. Having said that, new electric powered powertrain technologies offer you a pathway to decarbonization for this critical auto phase.

Spatial and Temporal Assessment of the TCO for Course 8 Tractors and Course 4 Parcel Delivery Vehicles compares six truck powertrain systems to quantify their TCO and determine running situations where by just about every technological know-how may have an financial benefit. The powertrains analyzed contain common diesel, diesel hybrid electric, plug-in hybrid electric, compressed organic gas, gasoline mobile electrical, and battery all-electrical.

“Our aim was to deliver a quantitative comparison of several powertrains to spotlight the prospective lifetime implications of each technological know-how,” mentioned Chad Hunter, guide writer of the report and previous NREL researcher. “This evaluation discovered that battery-electric powered and hydrogen-electric powered powertrains could have a competitive TCO as early as 2025, even for Course 8 vehicles, which are notoriously tricky to decarbonize.”

This TCO review quantifies indirect prices — for example, the charge of shed cargo capacity due to a heavier powertrain or the charge of dwell time invested refueling or recharging — along with the direct charges of acquiring, sustaining, fueling or charging, and driving a auto. Understanding these indirect charges is crucial to being familiar with the complete economic implications of a shift toward zero-emission transportation.

Introducing T3CO: An Integrated, Flexible TCO Modeling Method

The investigate leveraged NREL’s Transportation Technologies Total Value of Ownership (T3CO) modeling framework, which allows levelized assessments of the total everyday living-cycle prices of superior commercial automobiles. T3CO combines the electric power of two present NREL instruments, the Long run Automotive Units Know-how Simulator (FASTSim) and the Situation Analysis and Regionalization Investigation (SERA) design, to account for the various efficiency and economic requirements for medium- and hefty-responsibility autos.

“Total price tag of possession is a person of the most vital metrics for mass adoption of electrified professional vehicles,” reported Alex Schroeder, manager of NREL’s Advanced Automobiles and Charging Infrastructure team. “We identify that commercial car or truck technologies and functions will proceed to evolve and purposely sought to make T3CO versatile, extensible, built-in, and open up. A good deal of stakeholder input educated its progress, and we’re thrilled to see it evolve and develop by way of continued partnerships.”

T3CO options an stop-to-finish, integrated method for evaluating all expenses and enabling regular comparisons throughout technologies and vocations.

A Potential for Decarbonization of Large-Obligation Vehicles

Making use of the new T3CO design, NREL researchers assessed all immediate and oblique charges for every powertrain technological innovation for 3 distinctive truck vocations: Course 8 lengthy-haul (500–750-mile variety), Class 8 short-haul (300-mile vary), and Class 4 parcel shipping and delivery (120-mile selection). To further the investigation, scientists in contrast the powertrains for various timeframes to illustrate how battery and hydrogen fuel value reductions are vital to accelerating medium- and large-obligation motor vehicle electrification.

“Our investigation indicates that refueling and recharging charge administration must be a important target for upcoming research and improvement,” Hunter stated. “Electricity and hydrogen gas rates are central elements to the TCO of the battery and fuel mobile electric trucks evaluated in this report.”

At NREL, the Advanced Investigate on Integrated Electrical power Techniques (ARIES) investigate platform will aid R&D to obtain these engineering improvements and price tag reductions.

“One of the vital results from this analyze is that it aids us to hone upcoming investigation priorities,” Schroeder said. “The ARIES platform becoming set up at NREL is expressly developed to present expense-helpful megawatt-scale charging and superior-throughput hydrogen fueling.”

This extensive comparison across systems represents major coordination across the U.S. Department of Power Business of Strength Efficiency and Renewable Energy’s Hydrogen and Fuel Cell Technologies Business office and Car or truck Systems Place of work and leverages TCO studies designed by other DOE nationwide laboratories.
