Energy
Hydrogen, EVs, and RNG—Which Fuel Wins the Future of Clean Transportation?
The race to replace gasoline reveals a fragmented future where competing technologies each hold promise for different transportation challenges
Key takeaways
ACT Expo 2025 (April 28–30, Anaheim) will showcase peer-to-peer fleet case studies across electric, hydrogen, and RNG technologies.
Fleets are increasingly evaluating clean technology through the lens of financial and operational feasibility, not just sustainability mandates.
Infrastructure gaps—including grid capacity and hydrogen fueling logistics—remain key barriers to scaling clean commercial transportation.
Transportation is one of the largest sources of greenhouse gases generated by energy use globally, with over one billion oil-powered vehicles contributing to the challenge of achieving climate goals. That said, the transition to clean transportation is accelerating, and nowhere is that more evident than in the commercial fleet sector. As regulatory pressure shifts toward sustainability goals, companies are navigating a complex landscape of alternative fuels, zero-emission vehicles, and infrastructure challenges. With more than 460 exhibitors and a full-scale takeover of the Anaheim Convention Center, the upcoming Advanced Clean Transportation (ACT) Expo promises to be the largest and most impactful yet.
With fleets exploring electric, hydrogen, and renewable natural gas options, one key question looms: What strategies are truly working in the shift to clean trucking?
Welcome to Hammer Down. In this episode, host Mike Bush sits down with Lawren Markle, the Director of Media Relations at the Clean Transportation Solutions Team at TRC, which hosts the ACT Expo. The duo dives into what's ahead for ACT Expo 2025, the real-world successes and challenges of fleet electrification, and how businesses can cut through the noise to build an effective clean transportation strategy.
Key takeaways from the conversation…
- Fleet Case Studies & Technology Deep Dives: ACT Expo 2025, to be held from April 28-30, will feature peer-to-peer learning opportunities, showcasing real-world implementations of electric, hydrogen, and natural gas-powered fleets.
