In 2019, traffic-related CO2 emissions in Austria rose for the fifth time in a row and now are about 24 million tons. The target of 21.9 million tonnes set in the Climate Protection Act was thus far missed and we are already 8.3 million tonnes away from the climate target for 2030. The main cause of greenhouse gas emissions (excluding emissions trading) is still the transport sector. As described in the European hydrogen strategy, the use of renewable hydrogen and the energy sources derived from it will make an important contribution to the decarbonisation of the transport sector in the future. However, there are many ways in which renewable hydrogen can be used in mobility, and Austria will increasingly have to access hydrogen imports. In such a scenario, hydrogen storage is even more of a challenge after long transport routes have to be overcome. Ammonia is one of the most promising hydrogen carriers that is being discussed intensively around the world now.The central aim of this exploratory project is the development of a holistic assessment of the most promising hydrogen supply paths for mobility. A comparative techno-economic and ecological assessments will be carried out – starting with green hydrogen through to the end use in mobility. In addition to the direct hydrogen path, different hydrogen carrier systems (nitrogen, carbon, LOHC) are also assessed. The overall assessment also includes a separate assessment of the respective storage and logistics paths for the different production sites (AT and overseas).In the case of hydrogen carrier systems, emphasis is placed on the ammonia system and additional in-depth analyzes are carried out with regard to the achievable H2 quality in the decentralized reconversion of ammonia into hydrogen (ammonia cracking). In addition, the potential of direct ammonia use in a high-temperature fuel cell (SOFC) and in an ammonia fuel cell (DAFC) is estimated.
The innovation content of the project lies in the evaluation of new technologies to provide hydrogen or hydrogen-based fuels for mobility. These new technologies should enable mobility that is more energy-efficient, climate-friendly and safer than the previously known routes, and thereby promote the acceptance of hydrogen for mobility.The results achieved in the exploratory project contribute to a better decision-making for stakeholders and politics with regard to the further development of hydrogen production facilities and the development of the necessary supply infrastructure. An ecological and economic assessment, and the identification of potential improvements in the hydrogen paths based on technological developments, as well as the early detection of possible implementation barriers is extremely important for development of efficient and sustainable mobility in Austria.
