Implementing hydrogen as a transportation fuel in an environmentally sound way necessarily requires a sustainable concept for the provision of the hydrogen used as a fuel. However, there are various possibilities for generating hydrogen from renewable and fossil sources of energy. For example, hydrogen production from wind energy or solar radiation via electrolysis or from biogas via steam methane reforming are methods currently under discussion. However, there are many other provision chains, and the environmental performance of such chains is significantly influenced by their design, that is, the location and type of hydrogen production, the distances involved, and the pressure for hydrogen transportation. Therefore, the overall goal of this chapter is to assess different possible hydrogen supply chains for greenhouse gas (GHG) emissions from a life cycle perspective. Additionally, the sensitivity of the GHG emissions to the design of the provision chain (e.g., transportation distances, location of the production facility) will be assessed. Different framework conditions, such as electricity or feedstock provision, are also analyzed. Based on these variations, promising hydrogen provision chains with minimized GHG emissions will be identified for the mobility sector.
