Fuel cell cars are far from mass market production. But Hyundai, which is introducing fuel cell trucks in Switzerland, believes hydrogen technology could also play a bigger role in small vehicles further down the road. read more H2 Mobility operates 91 hydrogen filling stations and is expanding. H2 Mobility Managing Director Nikolas Iwan said the group was looking for anchor customers to bring big volumes to the stations, hoping this will allow them to reach break even within two to three years.
