The role of the ZSW in the project was to compile a CO2 potential atlas. The carbon dioxide potential had mainly been calculated as a whole until now, therefore the aim was to generate a geographical database pinpointing the relevant locations in Germany. The brief was to map the availability of CO2 sources throughout Germany by way of georeferenced information on the CO2 sources (geographic coordinates, addresses, postcodes) and to add more information (attributes) to the database, such as the potential quantities, the supply dynamics (annual availability) and the original substrates (biogenic sources, industrial emissions, etc.).
More than 10 different sources (registers, lists, etc.) were used to populate the database. The database was designed in such a way as to allow the incorporation of future updates from different sources in just a few steps. Another avenue was to evaluate 12 surveys covering a total of 34 scenarios for a comparison of the literature on CO2 emission data and to process the information so that the present and forecast demand could be seen against the supply of CO2 in Germany. Forecast figures were then taken from a selection of the above scenarios which could be used for the new database, thereby also enabling an insight into future review years (2030, 2040, 2050). The final step was to draw up criteria for PtX sites and incorporate them into the GIS system (geographical information system) together with the georeferenced facilities, at which point it was possible to identify potential locations and even analyse some of these examples.
The E2Fuels project was funded by the Federal Ministry for Economic Affairs and Climate Action (Bundesministerium für Wirtschaft und Klimaschutz - BMWK) under grant reference 03EIV011(E) as part of the research initiative “Energy Transition in the Transport Sector”.
