Hatabayeho ingamba zifatika, IEA ivuga ko imyuka ihumanya ikirere iva mu kirere izamuka 130% muri 2050 guhera ku rwego rwa 2005. Dioxyde de Carbone gufata no kubika (CCS) niyo ihendutse kandi, ku nganda zimwe na zimwe, inzira yonyine yo kugera ku kugabanya karubone. Kandi ni bumwe mu buryo butanga icyizere cyo kugabanya ibyuka bihumanya ikirere ku rugero runini kandi ubushyuhe bukabije ku isi.
Mu 2021, Komisiyo y’Uburayi yakiriye ihuriro ryo ku rwego rwo hejuru kuri CCUS, ryagaragaje ko ari ngombwa guteza imbere iterambere no kohereza imishinga y’ikoranabuhanga rya CCUS mu myaka icumi iri imbere niba intego za 2030 na 2050 zigomba kuzuzwa.
CCUS ikubiyemo urwego rwose rw'ikoranabuhanga rwo gufata karubone, gukoresha karubone no kubika karubone, ni ukuvuga dioxyde de carbone isohoka mu nganda zikora inganda zifatwa mu mutungo wongeye gukoreshwa hifashishijwe ikoranabuhanga rigezweho kandi rishya, hanyuma rigasubira mu bikorwa.
Ubu buryo bwongera imikorere ya karuboni ya dioxyde de carbone, kandi karubone yafashwe neza irashobora "guhindurwa" mubitungwa bikwiranye na plastiki yangiza ibinyabuzima, ibinyabuzima, ndetse no kongera gaze gasanzwe. Byongeye kandi, dioxyde de carbone yafatiwe muri geologiya nayo izagira uruhare rushya, nko gukoresha ikoranabuhanga ry’umwuzure wa karuboni, kongera ingufu mu kongera amavuta, n'ibindi. Muri make, CCUS ni inzira yo gukoresha siyanse n’ikoranabuhanga mu "ingufu" karubone dioxyde, guhindura imyanda mubutunzi no kuyikoresha byuzuye. Ibikorwa bya serivisi byagiye byiyongera kuva mu ngufu kugera mu nganda z’imiti, amashanyarazi, sima, ibyuma, ubuhinzi n’ibindi bice by’ibyuka bihumanya ikirere.
Umuvuduko ukabije wa gaz gaz CO2gufata ikoranabuhanga
• CO2ubuziranenge: 95% - 99%
• Gusaba: Gazi ya flue gaz, gazi yumuriro wa gazi, gaze itanura, gaze ya feri ya kokiya nibindi.
Kunoza tekinoroji ya MDEA decarbonisation
• CO2ibirimo: ≤50ppm
• Gusaba: LNG, uruganda rutunganya gaze yumye, syngas, gaze ya coke nibindi.
Umuvuduko wa swing adsorption (VPSA) tekinoroji ya decarbonisation
• CO2ibirimo: ≤0.2%
• Gushyira mu bikorwa: Ammonia ya sintetike, methanol, biyogazi, gaze ya myanda n'ibindi.
