The widespread availability of a robust and efficient charging network is poised to revolutionize the electric truck industry by 2035. Recent research conducted by the Oeko-Institut sheds light on the potential for increased new registrations of battery electric trucks, with the goal of reaching 100% adoption. This article will delve into the key findings of the research, emphasizing the critical importance of a rapid and targeted rollout of a charging infrastructure for heavy-duty commercial vehicles.
The research conducted by the Oeko-Institut compared various drive technologies in road freight transport to determine their technical and economic potential. The results overwhelmingly point towards battery electric trucks as the most viable option for the future. Even with conservative assumptions about factors such as potential ranges and available charging options, battery electric trucks outperform trucks powered by fuel cells or overhead lines.
The Cost Factor and Uncertainty
When considering the total cost calculations, it becomes clear that fuel cell vehicles are significantly more expensive than their pure electric counterparts. This disparity stems from the considerable uncertainty surrounding hydrogen prices. On the other hand, trucks relying on overhead lines face a major limitation – they can only operate on routes equipped with these lines, Hindering the fleet electrification process.
Dr. Katharina Göckeler, project manager and expert in low-carbon freight transport at the Oeko-Institut, highlights the cost advantages of zero-emission vehicles over conventional diesel-powered heavy goods vehicles. By December 2023, when the truck toll imposes a surcharge of 200 euros per ton of carbon dioxide, all zero-emission vehicles will yield clear cost benefits. This realization further solidifies the case for transitioning to electric trucks.
The reduction in greenhouse gas emissions from road freight transport post-2030 is expected to be significant, eventually reaching zero in 2045. The increased adoption of battery electric trucks will contribute to this reduction, as electric drive technology is far more operationally efficient than traditional combustion engines. Consequently, the transition to electric trucks will lead to a decrease in final energy consumption in road freight transport.
To ensure the successful integration of electric trucks into the market, a substantial expansion of the public charging infrastructure for heavy-duty commercial vehicles is imperative. Specifically, charging hubs must be strategically established along motorways, capable of accommodating both overnight and rapid charging. The needs assessment suggests that around 55% of a truck’s total energy demand can be charged at the depot before departure, with another 25% charged overnight using public night charging systems (NCS) for multi-day journeys. The remaining energy requirement should be met through high power charging solutions en route.
Charging Infrastructure Requirements
According to Dr. Katharina Göckeler, approximately 2,000 Megawatt Charging System (MCS) charging points and roughly 40,000 Night Charging Systems (NCS) charging points are needed along Germany’s motorway network. MCS charging stations, which require a connection to the high-voltage grid, enable rapid charging within the legally prescribed 45-minute rest period after 4.5 hours of driving. Planning for the rollout of these charging stations should commence promptly to ensure seamless integration.
The research conducted by the Oeko-Institut offers valuable insights into the future of electric trucks. With a robust and well-performing charging network in place by 2035, the potential for achieving 100% new registrations of battery electric trucks is within reach. The advantages of electric trucks over other drive technologies, coupled with the cost benefits and environmental impact, make them an attractive option for the future. However, the expansion of the charging infrastructure is pivotal to the successful adoption of electric trucks. Initiatives to establish charging hubs and fulfill the energy requirements of heavy-duty commercial vehicles must be prioritized, ensuring a seamless transition towards a sustainable transportation industry.
