This March, Shell presented a new study carried out in collaboration with the Wuppertal Institute for Climate, Environment and Energy. Focusing on transportation, the authors compared several different production pathways for hydrogen and took a closer look at the three regions spearheading global development: Germany, Japan and the United States. Jörg Adolf, who headed the project at Shell, said that hydrogen technology had made big advances over the past years, “not just in car use.”
