Aspekte der Energiewende. Teil 2: Wie kann der zukünftige heimische Bedarf an PTX-Produkten gedeckt werden und was werden sie kosten? Aspects of the Energy Transition. Part 2: How Can the Future Domestic Demand for PTX Products Be Covered and what Will they Cost?

Abstract

Based on the costs to produce PTX products, a simple computational model is presented to determine the costs to ship and to reform them into hydrogen. In this model, wind farms are the sole energy source for PTX production. As an example, the costs of transporting power-to-X (PTX) products NH₃, MeOH, liquid organic hydrogen carrier (LOHC), and Fischer-Tropsch diesel from Chile (Haru Oni) and Morocco (Tarfaya) are determined. These costs are compared with those of hydrogen production at three domestic locations with very good to very moderate wind conditions in the order Dornum (North German coast), Senftenberg (Lausitz), and Ludwigshafen (Rhine Graben). In addition, a cost comparison for Fischer-Tropsch diesel is made and land requirements for domestic production are determined.
