What’s New
The United States’ first hydrogen-powered passenger train, named ZEMU (Zero Emission Multiple Unit), has officially entered service in San Bernardino County, California.
Key Highlights
- Clean Energy Milestone: ZEMU emits only water vapor, offering a zero-emission alternative to diesel-powered commuter trains.
- Route & Capacity: The train operates on a 9-mile stretch between San Bernardino and Redlands, accommodating more than 100 passengers per trip.
- Technology & Range: Powered by hydrogen fuel cells, ZEMU can travel up to 350 miles on a single hydrogen fill, significantly cutting greenhouse gas emissions.
- Public-Private Partnership: Developed by the San Bernardino County Transportation Authority in collaboration with Stadler Rail, the project highlights strong regional commitment to clean mobility.
Why It Matters
- A major milestone for zero-emission rail in the U.S., paving the way for hydrogen-powered trains in additional states.
- Supports California’s climate objectives and demonstrates the feasibility of hydrogen infrastructure in public transportation.
Looking Ahead
- This deployment represents significant progress for zero-emission rail and could inspire expansion into longer routes as hydrogen supply networks scale.
- It showcases how hydrogen can integrate into broader clean mobility plans across California and beyond.
Bottom Line
The ZEMU train demonstrates that hydrogen can reliably power long-distance passenger rail, setting the foundation for a cleaner, more sustainable future in U.S. transportation.
