The two-car FLIRT-H2 can seat 108 passengers over two cars with a power pack in the middle. The power pack contains tanks of hydrogen and fuel cells that convert hydrogen into electricity, which is stored in a battery and then used to power the train. The train was built for the San Bernardino County Transportation Authority in Southern California, where it is slated to go into use later this year. Other public transit may be getting a hydrogen-powered overhaul as well: The California Air Resources Board mandated that bus fleets statewide must be converted to produce zero tailpipe emissions by 2040.
The biggest advantage of hydrogen fuel is that it produces no greenhouse gas emissions or pollution, but that comes with a caveat: According to a January report from the Information Technology and Innovation Foundation, 98 percent of hydrogen currently produced is “gray,” meaning it uses natural gas or gasified coal in its production. In other words, it’s not carbon neutral. Hydrogen is only considered “green” when renewable energy is used to generate electricity.
Robin Gaster, the report’s author, toldGovernment Technology that green hydrogen isn’t yet competitively priced with other energy sources. But that doesn’t mean it’s not possible. Rather, the report says, “we need a pathway through the green transition.
