Abstract

The decarbonisation of private transportation remains a challenge to tackle climate change. The utilization of green hydrogen for fuel cell electric vehicles offers a solution for that issue, but the hydrogen supply chain from production to refueling has lots of technological alternatives. The research objective of this work is to evaluate hydrogen infrastructure alternatives to supply the mobility sector with hydrogen and identify relevant technologies for that application in different regions. Furthermore, the influence of regional boundary conditions on the technology selection has to be investigated while drawing conclusions about the transferability of the given results. To achieve these objectives, a techno-economic model for the evaluation of various hydrogen supply chains was developed. Hence, different application areas depending on transportation distance and hydrogen demand were identified. The biggest area was occupied by hydrogen storage in salt cavern, transmission via pipeline and distribution by gaseous compressed hydrogen in trailer. An increasing hydrogen demand favors efficient, but cost-intensive systems like salt caverns or pipelines. In a second step, the techno-economic model was expanded by additional GIS based methods to implement regional features into the analysis. Afterwards, the model was applied on Germany, France and Japan for three different stock shares of fuel cell electric vehicles (25 %, 50 %, and 75 %).The individual regional features of each country have always impact on the final technology selection. Nevertheless, geological storage formations and transmission pipelines are identified as key technologies for future hydrogen supply systems. Liquid hydrogen is cost-competitive if geological storage options like salt caverns are not available. Meanwhile, the promising LOHC technology requires further research especially regarding the CO2 lean heat supply of the dehydrogenation. Finally, all investigated hydrogen supply chains enable CO2 lean mobility with fuel cell electric vehicles. The most important factor remains the production of hydrogen with low greenhouse gas emissions.
