Electric semi-trucks are more expensive upfront but have lower total ownership costs
Electric semi-trucks are an emerging solution for decarbonizing the shipping sector and reducing local air pollution. They are zero-emission vehicles that offer several benefits, including improved safety, reduced noise, and lower total ownership costs. However, they also come with upfront costs that are significantly higher than their diesel counterparts.
The upfront cost of an electric semi-truck can be a major obstacle for carriers considering transitioning their fleets to electric. The purchase price of an electric semi-truck is currently up to 2.8 times higher than that of a diesel truck. For example, the Port of Oakland acquired Peterbilt 579EVs at a cost of $510,000 per semi-truck. The higher upfront cost is mainly due to the expense of the large batteries required for these heavy-duty vehicles.
However, electric semi-trucks have lower operating costs, which can provide a strong incentive for carriers to adopt them. Electricity is less expensive than diesel, and electric trucks have lower maintenance costs due to features like regenerative braking. A 2021 study estimated that an electric semi-truck with a 375-mile range would have a 13% lower total cost of ownership ($1.51 per mile) than a diesel model ($1.73 per mile), resulting in a net savings of $200,000 over the truck's lifetime.
While the initial investment in electric semi-trucks is higher, the total ownership costs are expected to be lower due to reduced fuel and maintenance expenses. This makes them a more cost-effective option in the long run, especially with the continued improvement in upfront and long-term economics, increased availability of charging infrastructure, and policy incentives promoting the adoption of electric vehicles.
The transition to electric semi-trucks is gaining momentum, with major fleets committing to transitioning at least 30% of their new heavy-duty truck purchases to zero-emission vehicles by 2030. While there are challenges, such as limited charger availability and manufacturing delays, initiatives like the Inflation Reduction Act and Infrastructure Investment and Jobs Act are addressing these issues. The increased adoption of electric semi-trucks will contribute significantly to reducing emissions and improving air quality and public health.

They produce zero emissions and have improved safety features
Electric semi-trucks are increasingly being seen as the future of the trucking industry. Companies like Walmart and Amazon are already adopting electric trucks, with Walmart aiming to reach zero emissions by 2040. In addition to helping the environment, electric semi-trucks also have improved safety features and produce zero emissions.
One of the most significant advantages of electric semi-trucks is their zero-emission status. By transitioning to electric models, major fleets are committing to reducing their environmental impact and improving public health. Diesel-fueled semi-trucks produce 18% of US vehicle emissions and emit pollutants that increase the risk of asthma attacks, heart attacks, strokes, lung cancer, and premature deaths. Implementing zero-emission trucking could prevent 66,800 premature deaths, 1.75 million asthma attacks, and 8.5 million lost workdays between 2020 and 2025. This would provide $735 billion in cumulative US public health benefits.
In addition to the environmental and health benefits, electric semi-trucks also offer improved safety features. For example, the Tesla Semi has a safety feature that can prevent jackknifing, a dangerous type of trucking accident where the trailer turns in the opposite direction of the cab, causing the truck to flip onto its side. The Tesla Semi's electric drivetrain includes individual motors for each wheel, allowing the truck to sense weight distribution and automatically correct and prevent jackknifing without driver intervention. Electric semi-trucks also use regenerative braking, which conserves energy and improves safety by eliminating the need for downshifting when driving down long or steep grades.
The eCascadia is another example of an electric semi-truck with advanced safety features. It includes Active Side Guard Assist (ASGA), which prevents the vehicle from turning right if there is a cyclist or pedestrian in the way. The eCascadia also has lane assist and other standard safety features that help operators avoid collisions. Volvo's VNR Electric comes with Active Driver Assist, a forward collision avoidance technology, and Active Grip Control, which improves maneuverability and control in slippery conditions, including gravel or weather-related loss of traction.
While the upfront costs of electric semi-trucks can be higher, the total cost of ownership is lower for electric vehicles due to reduced maintenance and fuel costs. As battery costs decrease and manufacturing scales up, the upfront costs of electric semi-trucks are expected to become more competitive with diesel models. With the right approach, electric semi-trucks have the potential to bring remarkable improvements to truckers, communities, and the environment.

There are limited charging stations for electric semi-trucks
Electric semi-trucks are heavy-duty vehicles that can help reduce emissions and slow global warming and climate change. While electric semi-trucks are anticipated to accelerate faster than traditional trucks, they may not be able to go as far as diesel trucks without recharging. The limited availability of charging stations is one of the challenges that companies face when considering the transition to electric semi-trucks.
There are 6,700 public DC (direct current) fast-charging stations in the United States, but most of them only serve passenger vehicles. The absence of a widespread heavy-duty truck charging network limits electric semi-trucks to regional routes with centralized private chargers at warehouses and trucking depots. The high-power charging requirements of electric semi-trucks present a unique set of challenges. Each kind of electric vehicle requires a different power level to charge, and offering high-power charging at the megawatt scale can require grid upgrades.
To address the limited availability of charging stations, the National Electric Vehicle Infrastructure Formula Program, part of the Infrastructure Investment and Jobs Act, requires states to plan for public charging stations every 50 miles along alternative fuel corridors. This legislation also funds research, demonstration, and deployment for low- and zero-emission transportation options, as well as expanded electric vehicle charging infrastructure for heavy-duty vehicles. Additionally, companies like Heliox and WattEV are providing rapid charging solutions for electric truck fleets, with high charging speeds and flexible options to meet the needs of the industry.
While the transition to electric semi-trucks comes with challenges, the benefits of reduced emissions, improved safety, and lower noise pollution are considerable. With investments in charging infrastructure and the development of new technologies, the electric trucking industry is moving towards a more sustainable future.
