The trains can reach speeds of up to 87 miles per hour and travel up to 600 miles without refueling — about equivalent to the range of diesel trains, said Shawn Litster, a professor of mechanical engineering at Carnegie Mellon University in Pittsburgh…

Litster said hydrogen-powered trains are a good option for Germany, Japan and other nations with limited petroleum reserves — as well as for the U.S. He said Amtrak, which offers passenger rail service across the country, could replace its diesel train-dominated fleets with hydrogen trains, and that these zero-emissions vehicles are a “great opportunity” for the company to adopt greener and more cost-effective technologies.

As the world’s largest producer of natural gas, he said, “there’s already a large amount of hydrogen being produced in the U.S. annually.”
