Evaluating Bio-Based CDR Pathways through an Integrated Energy-Land Optimization Framework for Germany

Short Introductive summary

Carbon Dioxide Removal (CDR) is increasingly recognized as a critical component in achieving climate neutrality, especially for industrialized countries like Germany. This study presents the integration of diverse CDR deployment scenarios into an existing bio-based CDR (bioCDR) optimization modeling framework tailored to the German context. We extend the model to incorporate scenario-based constraints reflecting varying policy, technological, and land-use assumptions. By simulating a range of future CDR pathways including afforestation, BECCS (Bioenergy with Carbon Capture and Storage), and biochar, we assess their technical feasibility, economic viability, and interaction with Germany’s energy and land systems. The results highlight trade-offs between carbon removal potential and system costs under different policy scenarios. Our findings provide actionable insights for policymakers on how to strategically integrate CDR into Germany’s long-term climate strategy while balancing environmental and socio-economic objectives.
