Summary of news on 'Experiment 'turns waste CO2 to stone'' Source: BBC Scientists think they have found a smart way to constrain carbon dioxide emissions - just turn them to stone "Of our 220 tonnes of injected CO2, 95% was converted to limestone in less than two years," said lead author Juerg Matter from Southampton University, UK. "It was a huge surprise to all the scientists involved in the project, and we thought, 'Wow With carbon dioxide concentrations in the atmosphere marching ever upwards and warming the planet, researchers are keen to investigate so called "carbon capture and storage" (CCS) solutions Previous experiments have seen pure CO2 injected into sandstone, or deep, salty aquifers Chosen sites - which have included disused oil and gas wells - have relied on layers of impermeable capping rocks to hold down the carbon dioxide
