Missed the latest webinar of the series on the latest published papers on carbon dioxide removal (CDR) research that focused on the paper ‘Energy Demand and Savings Opportunities in the Supply of Limestone and Olivine-Rich Rocks for Geochemical Carbon Dioxide Removal’?
Visit the page below that provides an overview of the main issues that were discussed and the video registration:
Some key takeaways from the discussion that was moderated by Serena De Marco with the participation of Stefano Caserini as a speaker and Stefano Cappello as a panelist:
Mineral-based CDR is intrinsically energy intensive.
Significant energy-saving potential exists along the supply chain.
Future feasibility depends on energy system decarbonisation.
Limestone availability is not a binding constraint at global scale.
Industrialisation is already underway, but at early TRLs.
Costs are dominated by electricty prices and scale.
Environmental risks are manageable but require careful design.
Regulation and permitting are the main near-term barriers.
MRV is central for credibility and market uptake.
A full-chain perspective strengthens policy relevance.
