Southern California Zero Emission Truck Infrastructure Study
SCAG’s “Southern California Zero Emission Truck Infrastructure Study,” published in July 2026, creates strategies and recommendations for expanding a regional network of public charging and fueling stations for zero-emission (ZE) trucks and supports statewide efforts to transition medium- and heavy-duty trucks to alternative fueling technologies. The study recommends a phased approach to station deployment and the infrastructure to address the needs of various truck markets as they transition to ZE fleets.
The study focused on battery electric and hydrogen fuel cell truck technologies, assessing their infrastructure requirements and integration into a regional network of fueling sites. The study identified how zero-emission truck infrastructure (ZETI) can support diverse operational models and regional zero-emission goals. The study also outlined how different technologies could complement each other to address varying operational needs of different service sectors. The recommendations reflect a mix of technologies and operational needs. A technical advisory committee of public and private sector stakeholders contributed comprehensive perspectives on the developing ZE landscape.
The study was funded by funded in part by the California Energy Commission’s Research Hub for Electric Technologies in Truck Applications Program in partnership with the Electric Power Research Institute.
