WEDNESDAY, JUNE 29 AT 7:00AM PACIFIC - Hydrogen has the potential to replace diesel as a fuel for trains, especially for long distances. The gas company Linde has just built the world's largest hydrogen refueling station for trains in northern Germany in collaboration with a local railway company. With a capacity of 1,600 kg of hydrogen per day, the station can fill up to 14 trains. The range of the trains is then 1,000 km.
