Whereas general monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions concepts provide a high-level framework for setting up site-specific monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions programmes and give general recommendations on potentially suitable techniques, the site-specific monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions plans need to take into account the identified location-specific risks. The procedure of transferring a general monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions concept to a site-specific monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions programme is exemplified for two sites representing the major 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%) options in Europe. One of the examples is on 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 a saline aquiferAn underground layer of fluid-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) with significant permeability to allow flow (Example A), while the other involves a depleted(hydrocarbon reservoir) one where production is significantly reduced gas fieldReservoir rock where most of the gas has been extracted from between the grains of rock (Example B). The two 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%) projects are at different stages of project development. The aquiferAn underground layer of fluid-bearing permeable rock or unconsolidated materials (gravel, sand, or silt) with significant permeability to allow flow site is Romania's NER300 candidate, whereas for the depleted(hydrocarbon reservoir) one where production is significantly reduced gas fieldReservoir rock where most of the gas has been extracted from between the grains of rock only preliminary capacity estimates are available. The authors of this section claim neither completeness of these monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions plans, nor full compliance with and comprehensive consideration of all (national) regulatory requirements.
