What is it about?
In our research, we delve into the complex landscape of greening transportation, focusing on the often-misunderstood environmental impact of Electric Vehicles (EVs) and a compelling alternative—e-fueled Internal Combustion Engines (ICEs). Contrary to popular belief, our findings reveal that the overall carbon dioxide (CO₂) emissions reduction potential between these technologies is remarkably similar. We challenge the notion of EVs as entirely emission-free by considering their life cycle and electricity generation phases. Notably, Electric Vehicles, while energy-efficient, face limitations in long-distance journeys due to their autonomy constraints and charging infrastructure. On the other hand, e-fueled ICEs, especially when employing Carbon Capture and Storage (CCS) in e-fuel production, showcase a significant advantage in certain emission phases. Our study underscores the need for a diversified approach to transportation decarbonization, suggesting that focusing solely on Electric Vehicles might not be the most efficient path. Exploring alternative fueling options like e-fuels, compatible with existing ICE vehicles, emerges as a crucial strategy for achieving a comprehensive and sustainable transition in the transportation sector.

Why is it important?
In this groundbreaking research, we unravel the complexities surrounding the decarbonization of transportation, particularly focusing on the environmental implications of Electric Vehicles (EVs) and the promising alternative of e-fueled Internal Combustion Engines (ICEs). Our study challenges prevailing assumptions by providing a holistic examination of emissions, encompassing not only driving phases but the entire life cycle and electricity generation aspects. What sets our work apart is the revelation that the overall carbon dioxide (CO₂) emissions reduction potential of e-fueled ICEs and EVs is remarkably similar, a finding that challenges the prevalent discourse on EVs as the sole solution for sustainable transportation. The timeliness of our research lies in the current global push towards electric mobility, making it crucial for policymakers, researchers, and the public to reevaluate existing perspectives. By advocating for a diversified approach and underscoring the viability of alternative fueling options like e-fuels, our work aims to shape a more nuanced and effective strategy for achieving a greener and sustainable future in the transportation sector. This timely insight into the comparative environmental impact of different powertrain technologies is poised to stimulate interest and discussions among a broad readership, influencing the ongoing discourse on the path to a more sustainable transportation landscape.
Perspectives
Crafting this article was an intellectually stimulating journey, fueled by a collective passion for unraveling the intricacies of transportation decarbonization. Collaborating with fellow researchers who share a commitment to understanding the environmental impact of emerging technologies, particularly Electric Vehicles (EVs) and e-fueled Internal Combustion Engines (ICEs), brought a sense of synergy to the project. The research process involved a deep dive into the nuances of powertrain emissions, challenging widely held assumptions and shedding light on the similarities in the overall carbon dioxide (CO₂) reduction potential between these technologies. Personally, this work has sparked a renewed interest in advocating for a diversified approach to sustainable transportation. It is my hope that this article serves as a catalyst for reshaping conversations in the field, encouraging a broader perspective on decarbonization strategies. In the rapidly evolving landscape of global mobility, where the push for electric solutions dominates discussions, I believe our findings provide a timely and valuable contribution, urging stakeholders to reconsider the singular focus on Electric Vehicles and explore alternative fueling options. Ultimately, I aspire for this work to spark meaningful dialogues and contribute to a more nuanced and effective trajectory for greening the future of transportation.
