Carbon dioxide capture and geological storage.
Carbon dioxide capture and geological storage is a technology that could be used to reduce carbon dioxide emissions to the atmosphere from large industrial installations such as fossil fuel-fired power stations by 80-90%. It involves the capture of carbon dioxide at a large industrial plant, its transport to a geological storage site and its long-term isolation in a geological storage reservoir...
متن کاملBuilding Confidence in Geological Storage of Carbon Dioxide
In recent years, carbon dioxide capture and its geological storage (CCS) has been recognized as one of the most effective tools to mitigate climate change with its vast potential and cost effectiveness. With this background, many countries around the world have started to study on its technical aspects as well as economic aspects. In some countries, several commercial or experimental plants are...
متن کاملPore-scale imaging of geological carbon dioxide storage under in situ conditions
[1] While geological carbon dioxide (CO2) storage could contribute to reducing global emissions, it must be designed such that the CO2 cannot escape from the porous rock into which it is injected. An important mechanism to immobilize the CO2, preventing escape, is capillary trapping, where CO2 is stranded as disconnected pore-scale droplets (ganglia) in the rock, surrounded by water. We used X-...
متن کاملPermanent storage of carbon dioxide in geological reservoirs by mineral carbonation
Atmospheric CO2 concentration has increased from 280 ppm during pre-industrial times to 380 ppm today as a result of human input, and this is thought to be causing enhanced global warming and ocean acidification1. Between 2000 and 2005, global CO2 emissions from burning fossil fuels averaged 26.4 Gt CO2 yr−1, at or above the highest rates predicted by the Intergovernmental Panel on Climate Chan...
متن کاملDesign of carbon dioxide storage in aquifers
We propose a carbon storage strategy where CO2 and brine are injected into an aquifer together followed by brine injection alone. This renders 80–95% of the CO2 immobile in porescale (10 s mm) droplets in the porous rock. Over thousands to billions of years the CO2 may dissolve or precipitate as carbonate, but it will not migrate upwards and so is effectively sequestered. The CO2 is trapped dur...
