The FLIRT H₂, the first zero-emission, hydrogen-powered passenger train in the US, is set to revolutionize rail travel in Southern California. Operating on a short but significant 9.6-mile route between San Bernardino and Redlands, this innovative train promises passengers a quieter and more environmentally friendly journey compared to traditional diesel-powered trains. Manufactured by Swiss company Stadler Rail, the FLIRT H₂ made headlines by setting a world record for the longest distance traveled by a prototype hydrogen fuel cell electric multiple unit train without refueling. Stadler's CEO emphasized the company's forward-thinking approach by utilizing hydrogen as a clean energy source, contributing to environmental protection and sustainable travel practices. The US train industry's shift towards sustainability is evident, with Amtrak aiming for Net Zero emissions by 2045 and Stadler leading the way in producing narrow-gauge hydrogen trains. The introduction of the FLIRT H₂ marks a significant step towards a greener future in public transportation. Additionally, other modes of transportation, such as the ferry industry, are also joining the sustainability movement, with the expectation of the first hydrogen-powered ferry debuting in San Francisco this year.
