The North American Council for Freight Efficiency (NACFE) and ACT News have been collaborating since February to host a webinar series called Run on Less – Messy Middle Bootcamp. This series aims to help fleets navigate the complexities of transitioning to cleaner technologies. The final session, Bootcamp Finale Workshop, scheduled for July 15, will summarize insights from the past six months and prepare fleets for the forthcoming Run on Less – Messy Middle demonstration in September. The webinar series covered three main fuel categories: diesel and natural gas, battery-electric vehicles (BEVs), and hydrogen. It delved into the real-world applicability of these technologies and lessons learned from fleets already using them. The sessions began with a focus on low-carbon diesel and natural gas solutions, discussing renewable options and infrastructure challenges. Subsequently, the series explored battery-electric trucks, addressing technology status, infrastructure needs, and deployment strategies. The NACFE team then shifted its attention to hydrogen's potential in heavy-duty transportation. Sessions examined various aspects such as production, transportation, delivery to fleets, market conditions, and policy requirements for scaling hydrogen as a viable alternative fuel. Presenters discussed onboard storage, fueling station logistics, and the complexities and promises associated with hydrogen as an emerging fuel. The final Bootcamp webinar on July 15 will consolidate the top 10 insights, share feedback from fleets engaged in the Run on Less demonstration, and provide a preview of the upcoming activities in September. The overall sentiment of the article is positive, highlighting the collaborative effort to explore cleaner technologies in the trucking industry.
