The Southeastern Pennsylvania Transportation Authority (SEPTA) has introduced its first two hydrogen fuel-cell electric buses as part of its zero-emissions bus (ZEB) program. These buses are operating out of the Midvale depot in Philadelphia along Route 23, with plans for a total of 10 buses to enter revenue service. SEPTA is using this pilot program to monitor the performance of hydrogen buses across different terrains and weather conditions, gathering valuable data for future fleet decisions. The agency's long-term goal is to transition its diesel-electric hybrid buses to a fully zero-emissions fleet. The benefits of ZEBs highlighted by SEPTA include zero tailpipe emissions, lower greenhouse gas emissions compared to fossil-fuel vehicles, and decreased noise pollution due to the absence of traditional combustion engines. The new buses also feature custom exterior wraps by local artist Amberella, adding a unique touch to the initiative. Overall, the introduction of hydrogen fuel-cell electric buses represents a positive step towards improving air quality, promoting sustainability, and advancing innovative public transportation solutions in Philadelphia.
