Fleet managers of light commercial vehicles are exploring the economic implications of transitioning to cleaner solutions like hydrogen fuel cell electric vehicles (FCEVs) amidst strict transport emission regulations. While FCEVs have higher initial purchase costs, subsidies and economies of scale are expected to make them more affordable over time. The operating and maintenance costs of FCEVs offer advantages in energy and maintenance, making them competitive with diesel and BEVs in the long run. Total Cost of Ownership (TCO) analysis highlights the increasing viability of FCEVs as hydrogen costs decrease, particularly for long-distance fleets. Infrastructure development, such as the expansion of hydrogen refuelling stations through public and private initiatives, plays a crucial role in facilitating the transition to FCEVs. The collective efforts of countries and industries in developing a supportive infrastructure are essential for maximizing the economic benefits of adopting FCEVs.
