Hydrogen can make a significant contribution to CO2 reduction in the transportation sector and play a key role worldwide for sustainable mobility, especially once production capacities based on renewable energy sources are established on a long-term basis.

Hydrogen is the most abundant chemical element in the universe. However, it does not occur in nature in pure form, but must be separated from hydrogenous compounds; these processes require energy input. Hydrogen is thus not a primary energy source such as petroleum, natural gas, coal, biomass, wind, water, solar energy or geothermal power, but is produced from or by means of these energy sources. Hydrogen as an energy medium or a fuel, can secure sustainable and unrestricted mobility in fuel cell vehicles.
