Show Notes: Transitioning Transit Fleets to Zero Emissions

John Havrilla from Wendel, an architectural andengineering firm with an area of focus on facilities upgrades, discusses various aspects of transitioning transit fleets to alternative fuels, focusing on the challenges and solutions encountered in the process.

There was a discussion around first responder training and battery fires. Wendel created a white paper to discuss battery safety that can be found here: https://wendelcompanies.com/indoor-battery-electric-bus-charging/

Working closely with utilities is essential, John explains, as they play a significant role beyond providing power for electric vehicles (EVs). Collaborating on rate structures, managing demand charges, and structuring cost-effective plans for transit clients are key areas of focus. Phasing and transition plans are crucial to optimize utility benefits and accommodate evolving needs over time.

Space constraints pose significant challenges during the transition. John highlights the example of an older facility in Stanford, where structural modifications were necessary to accommodate new equipment for EV charging. Creative solutions, such as innovative placement of charging equipment, are employed to overcome these limitations while ensuring efficient operations.

When planning new facilities, flexibility in design is paramount to accommodate future transitions to alternative fuels. Factors such as reliable power access, site planning for power infrastructure, and potential space reservations for future fueling needs must be considered. The evolving requirements for parts storage and maintenance facilities are also addressed, particularly in the context of transitioning from diesel to electric buses.

Inductive charging technology presents both challenges and potential benefits for zero-emission fleets. While its wireless capabilities are appealing, challenges such as limited suppliers, proprietary equipment, and the absence of standardized approaches must be overcome. Bus manufacturers are hesitant to adopt inductive charging without a uniform standard, highlighting the need for collaboration to establish reliable standards in the industry.
