TGGS - ECE Seminar "eFuels, hydrogen or batteries"


ECE Seminar „eFuels, hydrogen or batteries – Which technology for different mobility application?”

In order to achieve the CO2 reduction necessary to slow and then limit the global temperature rise, the mobility sector must also become CO2 neutral. Various technologies are available for this. In addition to battery-electric vehicles, propulsion systems using hydrogen via fuel cells or hydrogen combustion engines and eFuels or biofuels are also being discussed. eFuels are produced from hydrogen as a basic material and can then be processed, for example, with carbon from CO2 into fuels that are chemically very similar to petrol and diesel or also with nitrogen to ammonia into liquid fuels.

All forms of propulsion have advantages and disadvantages. Important factors are, for example, energy densities and thus weight, efficiency chains and thus overall efficiency, storability and the infrastructures needed to produce and distribute the energy sources.

At the same time, different application areas of mobility have very different requirements and boundary conditions. Passenger vehicles, trucks for distribution and long-distance operation, buses and trains for inner-city traffic and the connection of cities, ships on rivers and seas, aircraft for short distances and intercontinental travel, construction or agricultural machinery must each be analysed in relation to the suitability of the different energy carriers, for which the questions of infrastructure, for example, again play an important role.

The seminar will discuss the state of the art of the various technologies, the development of global markets, international supply chains and transport costs. For this purpose, the options for the different mobility sectors will be systematically analysed and predictions for the technologies likely to dominate in the coming years will be derived from this.

The seminar is divided into four videos.
