Hyundai announced that it plans to produce a hydrogen-fueled SUV in 2014—the first mass-market vehicle to be powered by hydrogen fuel cells. The 2014 Hyundai Tucson was unveiled Wednesday at the Los Angeles auto show, which also featured a fuel-cell concept car from Honda. Toyota alsounveiled its concept fuel-cell vehicle at the Tokyo Motor Show. Both Honda and Toyota expect to bring their fuel-cell vehicles to market in 2015.

Hydrogen fuel-cell cars face a challenge familiar to advanced vehicles fueled by electricity and natural gas: fueling infrastructure is limited. California has just nine hydrogen fueling stations.

Despite that, “these things are now ready for prime time,” said John Krafcik, CEO of Hyundai North America. The hydrogen fuel-cell vehicles will help to satisfy the conditions of the new eight-state advanced vehicle coalition, which has committed to put 3.3 million new zero-emission vehicles on the road by 2025.
