The preliminary geological characterisation of potential CO2Carbon dioxide storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) sites includes site screening, preliminary storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) capacityThe accumulated mass of CO2Carbon dioxide that can be stored environmentally safely, i.e., without causing leakage(in CO2Carbon dioxide storage) The escape of injected fluid from the storage formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it to the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) or water column of CO2Carbon dioxide or native reservoirA subsurface body of rock with sufficient porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock and permeabilityAbility to flow or transmit fluids through a porous solid such as rock to store and transmit fluids fluids or triggering geologic activity that has a negative impact on human health or the environment assessment and then ranking leading to selection of optimal storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) site for a CCSCarbon dioxide CaptureThe separation of carbon dioxide from other gases before it is emitted to the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) and Storage project.
The whole process cannot be carried out without taking into consideration legal and regulatory, environmental, technical and even to some extent economic aspects of CO2Carbon dioxide geological storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%).
The most significant knowledge gaps and uncertainties may exist in the case of CO2Carbon dioxide storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) in saline aquifers, where often insufficient information is available to evaluate the sites in question against principal screening criteria. For onshore saline aquifers, criteria related to safety of underground potable water resources are considered the most important. Although offshore storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) does not relate to such problems, prevention of significant leaks from reservoirA subsurface body of rock with sufficient porosityMeasure for the amount of pore spaceSpace between rock or sediment grains that can contain fluids in a rock and permeabilityAbility to flow or transmit fluids through a porous solid such as rock to store and transmit fluids to the sea bottom through natural or man-made pathways is the main safety concern.
In the case of saline aquifers, it is often difficult to make a reliable site ranking and selection without acquiring new data, including drilling new exploratory wells, carrying out new seismic surveys and other characterisation surveys.
There are more possible conflicts of use of the subsurface in the case of onshore than offshore saline aquiferAn underground layer of fluid-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) with significant permeability to allow flow CO2Carbon dioxide storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) and fewer conflicts for depleted(hydrocarbon reservoir) one where production is significantly reduced hydrocarbon fields and un-mineable coal beds.
