Renewable Electricity from Germany or e-Fuels from Chile: What Should Future Mobility be Based on?
Germany will probably not be able to cover its future demand for renewable electricity itself. The transport of electricity from areas with a large generation potential for renewable electricity is very expensive. On the other hand, the transport of e-fuels, such as methanol, petrol, diesel or hydrogen, is cheap because an existing infrastructure can be used up to the filling stations and the transport of liquids over long distances costs much less than the transport of electricity. If these boundary conditions are taken into account in a cost calculation based on process simulations, the specific energy costs for e-fuels that are produced in windy regions of Chile and delivered to the German filling stations are lower than for renewable electricity that is produced in Germany and has to be transported to the charging stations via an appropriately developed electricity network.
