Abstract
Key insights:
- Overall cost trends: GGR cost estimates have increased, as compared to ERM's 2021 analysis, largely reflecting improved data availability and better clarity on previously uncertain factors. Transport and storage of captured CO₂, and MRV (monitoring, reporting & verification) remain major cost drivers across most GGR methods.
- DACCS & biochar costs: Greater visibility into subcategories of these methods reveals significant price variations—critical for informed decision-making.
- System boundaries matter: Standardization is essential for meaningful cross-comparison of GGR approaches.
- Beyond the numbers: Business models, regulatory barriers, and deep uncertainty must be factored into GGR strategies.
