Zero-emission trucks (ZETs) are on the rise across the United States, with over 52,500 vehicles now on the road, marking a significant 76% increase from 2023. While ZETs currently represent only 2.3% of new truck registrations, there is a clear need to double deployment to meet federal climate targets. The dominance of battery-electric vehicles contrasts with the limited presence of hydrogen fuel cell electric trucks, emphasizing the current market landscape. Cargo vans are leading the ZET market, accounting for 89% of all deployments, while yard tractors have the highest market share within their segment, showcasing their cost-effectiveness and reliability, especially in specific environments. However, the pace of adoption slowed in the latter part of 2024 due to policy uncertainties and inconsistencies at the state level. States like California, Texas, and Florida are at the forefront of ZET deployment, with Maryland showing remarkable growth in 2024. The significance of targeted regulations is evident, as states embracing the Advanced Clean Trucks regulation are driving market certainty and encouraging investments. Despite barriers such as high costs and slow infrastructure development, initiatives like comprehensive policies, shared charging sites, and state-backed financing mechanisms are seen as crucial for accelerating the adoption of ZETs. While progress has been made, achieving a nationwide transition will require stronger policy alignment and federal support to ensure a cohesive approach towards zero-emission truck deployment.
