At an American Public Transportation Association conference in Anaheim, California, transit agencies discussed the challenges and lessons learned in transitioning to zero-emission bus fleets. Cliff Henke highlighted the hurdles, including limited bus manufacturers, escalating prices, and the need for infrastructure upgrades. Jennifer Sweten of the Missoula Urban Transportation District emphasized starting with infrastructure improvements for successful fleet electrification in harsh climates like Montana. Conversely, SunLine Transit Agency in California opted for hydrogen fuel cell technology due to the extreme heat of the Coachella Valley. Insights from agencies included the importance of full commitment to the transition, avoiding pilot projects, and seeking knowledge from experienced counterparts. While costs remain a concern, especially in the U.S., panelists agreed that the shift to clean buses was essential for environmental reasons, even if not immediately profitable. The Federal Transit Administration provides grants to aid in purchasing low-emission buses and infrastructure support, but the economic payback may not be immediate. Despite this, the consensus was that transitioning to zero-emission fleets is a necessary step towards mitigating transportation emissions and addressing environmental concerns, such as those raised by wildfires.
