Fast-Falling Battery Prices Boost Economic Benefits Expected from Heavy-Duty Vehicle Electrification

The report argues that falling battery prices, driven by economies of scale and innovation (Wright's Law), will make battery electric heavy-duty vehicles (BEHDVs) more affordable than diesel equivalents sooner than previously estimated. Using updated BNEF forecasts, the study finds that by 2030, BEHDVs will be cheaper to purchase than diesel versions for four out of five analyzed vehicle types. This economic shift enhances the total cost of ownership (TCO) advantage and suggests that the benefits of the US EPA's proposed Phase 3 emissions standards are likely to exceed initial predictions.

• Updated forecasts indicate that battery electric heavy-duty vehicles (BEHDVs) will reach price parity with diesel vehicles faster than previously expected. By 2030, BEHDVs are projected to be less expensive than diesel equivalents for four of the five vehicle types analyzed.
• Class 6-7 rigid trucks are expected to show the most significant upfront cost advantage by 2030, with battery-electric versions saving $29,000 compared to diesel equivalents.
• Long-haul tractor trucks are the most difficult to electrify due to their large battery requirements, but they are expected to achieve a lower total cost of ownership (TCO) than diesel trucks before 2030, even without government incentives.
• The report identifies a significant downward trend in battery pack costs: BNEF forecasts HDV battery packs will cost $85 per kWh in 2030, $65 per kWh in 2035, and $59 per kWh by 2040.
• The decline in battery costs is attributed to Wright's Law, where cumulative deployment leads to predictable cost reductions. This is supported by the scaling of battery production capacity, which is projected to increase by a factor of four in 2030 compared to 2022 levels.
• The transition to BEHDVs addresses severe public health issues in the U.S., where diesel emissions are estimated to cause 8,800 premature deaths annually and HDVs contribute over half of road vehicle nitrogen oxides (NOx) emissions.
• The economic findings suggest that the benefits of the US EPA's April 2023 proposal for Phase 3 HDV emissions standards are likely to be greater than those estimated in the agency's Draft Regulatory Impact Analysis.
