The article discusses how hydrogen fuel cell cars need a special hydrogen refueling infrastructure. Car companies will soon sell these cars worldwide. While progress has been made in making codes and technology for hydrogen stations, setting up these stations is tough. Both governments and companies need to invest to build enough stations for people to buy fuel cell cars. Current work is focusing on developing high-pressure, clean hydrogen gas for vehicles. The main finding is that technology for fuel cell cars is advancing, but building hydrogen stations is falling behind what's needed for the market.
