Modeling approaches for marine Carbon Dioxide Removal (mCDR)

Session ID#: 259687

Session Description:
There is growing interest in marine carbon dioxide removal (CDR) approaches—including ocean alkalinity enhancement, direct ocean capture, nutrient fertilization, biomass sinking, macroalgae cultivation, and artificial upwelling—as a portfolio of approaches aiming to remove 10–20 gigatons of atmospheric CO₂ annually by mid- to late-century.

Modeling these approaches offers insights that enable assessment of carbon sequestration efficacy, permanence, and ecological impacts across broad spatial and temporal scales under various scenarios. These tools are critical for aligning mCDR deployments with climate goals and environmental safeguards.

This session invites contributions on the state of practice, and emerging paradigms, in modeling carbon removal and environmental impact assessment. We welcome topics including (but not limited to): microscale particle–environment interactions, nearfield and mixing-zone modeling, reaction transport and mineral dissolution modeling, micro- and macroalgal growth models, and regional to global-scale Earth system simulations. We also encourage contributions addressing uncertainty quantification, model coupling across scales, and the inclusion of underrepresented physical or biogeochemical processes. Finally, work that quantifies carbon sequestration potential, evaluates environmental impacts, and supports the development of monitoring, reporting, and verification (MRV) frameworks, is of great interest. We encourage participation from practitioners in research, industry, and academia.
