Direct deep-sea carbon dioxide injection was a (now abandoned) technology proposal with the aim to remove carbon dioxide from the atmosphere by direct...

more precisely it was known as "direct deep-sea carbon dioxide injection". However, the interest in this avenue of carbon storage has much reduced since...

concentration of carbon dioxide generated is measured with a non-dispersive infrared (NDIR) detector. Oxidation of the sample is complete after injection into the...

Carbon capture and storage (CCS) is a process by which carbon dioxide (CO2) from industrial installations is separated before it is released into the...
