Could diesel's continued dominance in transport sectors like shipping and trucking be safeguarded by new technological advancements?
In the ever-evolving world of transportation, the trucking industry is witnessing significant changes as it navigates the path towards sustainability. An international group of researchers has built a machine learning (ML) system that accelerates the identification of new fuel mixtures, potentially shortening the process by finding promising compositions in a matter of hours [1].
Meanwhile, decision-makers planning fleet enhancements are focusing on emissions-cutting technologies. For instance, near-zero-emission vehicles with integrated components like selective catalytic reduction systems are gaining attention [2]. However, current advancements in diesel technology for reducing emissions in the trucking industry, particularly in North America, are centred around improving efficiency and optimising diesel engines rather than replacing them entirely [1][2].
Daimler Truck, a leading manufacturer, is intensifying its investment in diesel engine development, planning a next-generation engine rollout starting in 2026. This new engine series aims to deliver major efficiency improvements while maintaining competitive emissions performance beyond 2030 [1][2]. The Heavy-Duty Diesel Platform (HDEP) powers several engines, offering a cost-effective global supply and market-specific customization [1].
Despite global pressure towards zero-emission vehicles, diesel is still considered the most viable option currently, particularly for heavy-duty and long-haul trucks in North America, due to infrastructure and technology maturity challenges around electric and hydrogen alternatives [1][2]. Advances are expected to address emissions reductions within internal combustion technology, likely through enhancements in combustion efficiency, aftertreatment systems, and possibly integrating mild hybrid systems [1][2].
Regulatory environments have shifted, such as the rollback of California’s stricter emissions standards, easing the transition pressure on fleets moving from diesel to zero-emission vehicles but still maintaining stricter federal NOₓ limits for new engines [3].
Amidst these advancements, the shipping and logistics industry is reassessing the pros and cons of transitioning from diesel. One innovative solution comes from California-based startup, Forum Mobility, which offers a subscription model for trucks and charging stations, making the transition to electric vehicles simpler for fleet managers [4]. A logistics client running 50 trucks daily now has several battery-electric vehicles and high-voltage charging stations, complementing its diesel models [4].
Technological improvements have also made diesel a greener choice for organizations aiming for sustainability goals. For instance, a lubricant has been developed that increases fuel efficiency in internal combustion engines by up to 8.4%, based on four years of controlled testing [5]. The graphene liquid concentrate boosts fuel efficiency during increased engine loads and enhances diesel engine performance in generators [5].
Artificial intelligence (AI) is being used in the shipping and trucking industry to support cleaner diesel operations. AI is being used to formulate biodiesel from ingredients like used cooking oils and to offset rising fuel costs, automating steps to find reasonably priced carriers and predicting fluctuating diesel prices, aiding budget planning [6]. These offerings will remain valuable until cleaner diesels become accessible and affordable.
Built-in sensors in trucks alert technicians to emissions-elevating problems, helping fleet managers optimise sustainability by identifying which aging vehicles to replace first [7]. For every electric truck, there are 1,100 internal combustion engine trucks [8]. Fleet managers must consider factors like charging station locations and government grant eligibility when considering a switch to electric trucks [8].
In conclusion, the trucking industry’s diesel advancements currently revolve around next-generation diesel engine designs that improve fuel efficiency and reduce nitrogen oxide (NOₓ) and particulate emissions by employing cutting-edge combustion and aftertreatment technologies. These are intended to keep diesel trucks compliant with emissions standards while addressing economic and infrastructure realities, particularly in North America where zero-emission truck adoption faces hurdles [1][2][3]. New technologies and business models offer greener alternatives without requiring a complete replacement of diesel fuels.
