Expenses and Temporal Dynamics of Bio-Based Carbon Dioxide Removal

Short Introductive summary

The political and societal debate around carbon dioxide removal (CDR) is gaining trajectory in Germany. Several political instruments on national and European level are in the final stages of development, like the national Carbon Management Strategy and the European Carbon Removal Certification Framework. CDR is indispensable for climate neutrality, as a complementary strategy alongside reducing and avoiding greenhouse gas emissions. To define and implement the possible contribution of bioenergy with carbon capture and storage (BECCS) and other bio-based CDR to Germany’s negative emission strategy, expenses and temporal removal dynamics are key. Bio-based CDR options include natural sink enhancement in forests, agricultural land and peatlands, renewable long-lived building materials, and BECCS. Their expenses are discussed against the background of temporal removal dynamics and CO2 storage durabilities associated with the respective option. By comparing the options, their inherently different dynamics become apparent, which suggests that a portfolio approach is best suited to achieve cost-efficient bio-based CDR.

Presenter's biography

Ms Wollnik researches bio-based negative emissions in the working group Biomass in the Energy System at the German Biomass Research Center. She studied Sustainability Science (M.Sc.) and Chemistry (B.Sc.). Her methodological focus is indicators and scenarios for an integrated technology assesssment.
