One niche market is gaining more and more attention from the industrial minerals industry: that of carbon dioxide (CO2) sequestration or storage, which aims to reduce greenhouse gas (GHG) emissions into the atmosphere.
Carbon capture and storage (CCS) is the process of capturing, transporting and storing anthropogenic CO2. The CO2 is sequestered from large industrial sources such as coal, oil and gas facilities before it is released into the atmosphere. It is then transported through pipelines - similar to those used to transport natural gas and oil - and permanently stored in reservoirs or in other deep geological formations. The selected storage sites are at depths of 1-5km below the surface and exhibit the geologic conditions necessary to ensure that these reservoirs can retain the CO2 for long periods of time. Small volumes of CO2 can also be transported as a liquid in ships, tanker trucks or rail tankers.
