Current and emerging laser sensors for greenhouse gas detection and monitoring

C02 is created by combusting fossil fuels, including natural gas, and is participating in climate change (5). To slow or reverse the trend of increasing atmospheric concentration of CO2, geologic carbon sequestration (GCS) is emerging as a strategy for restraining the anthropogenic C02 flux. GCS involves separating C02 from combustion effluent, transporting it via pipeline to storage sites, and injecting it at high pressure into storage reservoirs several thousand feet deep.
