The emissions related to hydrogenproduction facilities are shown in the annex. The emissions shown in table 2.1 are anexcerpt of this minimum list and were analysed to be most relevant for hydrogenproduction. They refer to one kilogram compressed gaseous hydrogen.The main emission into air is carbon dioxide. Regarding all the emissions the vastmajority comes from the fuel supply phase, i.e. the actual production of hydrogen byelectrolysis (see Figure 6 below). The emissions from the manufacturing phase of thefuelling station are dominated by the amount of steel and concrete used.
