greenSand will be present at the National CO₂ platform on 25 and 26 August 2010. The subject is Carbon Capture and Storage (CCS). Alternatives for underground storage of CO₂ will be examined, for example by capturing CO₂ aboveground, with the help of greenSand (=olivine). On behalf of the Olivine Group/greenSand, Professor Olaf Schuiling, geo-chemist, talks about how olivine cleans up CO₂. greenSand distributes sprinkle bags of olivine.
