Challenges and Advances in the Deployment of Carbon Dioxide Removal (CDR) Technologies

Achieving net-zero emissions requires both rapid decarbonization of the energy sector and the large-scale deployment of Carbon Dioxide Removal (CDR) solutions to manage legacy emissions and address hard-to-abate sectors. CDR technologies must transition from demonstration projects to industrial scale. While significant technological advances are being made in CDR, their successful implementation faces interconnected technological, systemic, and sociopolitical challenges.This Research Topic seeks to bridge the critical research gap at the nexus of these domains, moving beyond technology-only analyses to explore the systemic and societal hurdles that could slow or stall the progress of CDR deployment.The aim is to foster a holistic, interdisciplinary dialogue to understand how innovations in technology can be integrated to accelerate climate action through effective, equitable, and sustainable CO2 removal. Submissions are expected to offer technology and systemic perspectives on CDR deployment, providing a vital resource for researchers, policymakers, and industry stakeholders to design more effective and resilient systems for the future.Submissions are expected across all scales of CDR—from lab-based fundamental science to implementation in the field—provided they maintain a clear focus on the challenges and opportunities in deployment. Topics of interest include, but are not limited to:• Next-Generation CDR Technology - Novel methods and materials for direct air capture (DAC), enhanced mineralisation and biomass with carbon removal and storage (BiCRS) including life cycle and techno-economic analyses that assess scalability and resource competition;• The Energy-Water-Land Nexus - Integrated system analyses of the energy, water, and land footprint of large-scale CDR and dedicated storage infrastructure, and strategies to minimize environmental or agricultural conflicts;• Geopolitics and Supply Chains - Analysis of the critical mineral supply chains required for CDR infrastructure and the associated geopolitical risks, market dynamics, and resource security strategies;• Sociotechnical components - Frameworks for monitoring, reporting, and verification (MRV) and ensuring permanence; community benefit in the siting, funding, and operation of CDR projects.
