Along with efforts to reduce our greenhouse gas emissions, solutions are being tested to remove carbon dioxide from the atmosphere.
This is referred to as “negative emissions”.
The closest to success is called BECSC, for “bioenergy with CO2 capture and storage”.
The idea is to sustainably capture the CO2 trapped during the life of the plants, in particular by burning trees or agricultural crop residues in specialized factories, which produce electricity while recovering the CO2 in the fumes.

The main technology option is called 'afterburner capture,'
explains Daniel Quiggin, energy expert at UK think-tank Chatham House
.
It consists of passing the fumes through a solvent then, by heating the mixture, recovering the CO2, concentrating it, liquefying it and pumping it to geological formations.
In Britain, the reservoirs of the oil and gas industry constitute theoretical sites…
