The research project “SoIar2FueI” funded by the German Ministry of education and research (BMBF), EnBW AG and BASF SE within the Leading-Edge Cluster “Forum Organic EIectronic” aims to develop a future solar powered CO2 to methanol conversion technology. This technology would give rise to the possibility of recycling captured CO2 from stationary sources in Northern Europe, transport CO2 in large pipelines with 50 Mt annual capacity to regions with high solar irradiation where it can be converted into a renewable fuel via solar energy.
EnBW AG investigated the feasibility of different CO2 pipeline routes from Germany to Algeria, North Africa, using GIS (Geoinformationssystem) analysis and simulation tools for pipelines including the specific gas properties.
The pipeline was designed regarding pressure, pressure losses, compressor demand and wall thicknesses for the different topologies on- and off-shore. The cost of the total pipeline including compressor stations were analysed in simulations with different pipeline diameters. From this analysis the energy need for CO2 transport as well as the specific transportation cost from Germany to Algeria were calculated. In addition the requirements for CO2 storage and its specific costs are evaluated. The results of the costs of CO2 transport are compared with respect to its impact on solar methanol production.
