CCUS thev naus laus zis tuaj yeem txhawb nqa ntau yam haujlwm. Hauv kev ua haujlwm ntawm lub zog thiab lub zog, kev sib xyaw ua ke ntawm "lub zog hluav taws xob + CCUS" yog qhov sib tw heev hauv lub zog hluav taws xob thiab tuaj yeem ua tiav qhov sib npaug ntawm cov pa roj carbon tsawg thiab kev tsim hluav taws xob. Hauv kev lag luam, CCUS thev naus laus zis tuaj yeem txhawb kev hloov pauv ntawm cov pa roj carbon tsawg ntawm ntau qhov kev lag luam siab thiab nyuaj-rau-txo, thiab muab kev txhawb nqa rau kev txhim kho kev lag luam thiab kev tsim cov pa roj carbon tsawg ntawm cov khoom siv hluav taws xob. Piv txwv li, hauv kev lag luam steel, ntxiv rau kev siv thiab khaws cia cov pa roj carbon dioxide, nws kuj tuaj yeem siv ncaj qha rau hauv cov txheej txheem steelmaking, uas tuaj yeem txhim kho kev ua haujlwm ntawm kev txo qis. Hauv kev lag luam cement, carbon dioxide emissions los ntawm decomposition ntawm limestone account txog li 60% ntawm tag nrho cov emissions ntawm cov cement kev lag luam, carbon capture technology yuav ntes cov carbon dioxide nyob rau hauv tus txheej txheem, yog ib tug tsim nyog technical txhais tau tias rau decarbonization ntawm cov cement. kev lag luam. Hauv kev lag luam petrochemical, CCUS tuaj yeem ua tiav cov roj ntau lawm thiab txo cov pa roj carbon monoxide.
Tsis tas li ntawd, CCUS thev naus laus zis tuaj yeem ua kom txoj kev loj hlob ntawm lub zog huv. Nrog rau kev tawg ntawm hydrogen zog kev lag luam, fossil zog hydrogen ntau lawm thiab CCUS technology yuav yog ib qho tseem ceeb qhov chaw ntawm hydrocarbon tsawg nyob rau hauv lub neej yav tom ntej. Tam sim no, cov khoom tsim tawm txhua xyoo ntawm xya hydrogen ntau lawm cov nroj tsuag hloov pauv los ntawm CCUS thev naus laus zis hauv ntiaj teb yog siab li 400,000 tons, uas yog peb npaug ntawm hydrogen ntau lawm ntawm electrolytic hlwb. Nws kuj tseem xav tias los ntawm 2070, 40% ntawm lub ntiaj teb cov khoom siv qis hydrocarbon yuav los ntawm "fossil zog + CCUS thev naus laus zis".
Nyob rau hauv cov nqe lus ntawm emission txo cov kev pab cuam, CCUS 'tsis zoo carbon technology yuav txo tau tag nrho cov nqi ntawm kev ua tau zoo carbon neutrality. Ntawm qhov tod tes, CCUS 'tsis zoo carbon technologies suav nrog biomass zog-carbon capture thiab cia (BECCS) thiab ncaj qha pa carbon capture thiab cia (DACCS), uas ncaj qha ntes carbon dioxide los ntawm biomass zog conversion txheej txheem thiab cov huab cua, feem, ua tiav kev sib sib zog nqus decarbonization ntawm tus nqi qis thiab kev ua haujlwm siab dua, txo tus nqi ntawm qhov project. Nws tau kwv yees tias qhov sib sib zog nqus decarbonization ntawm lub zog hluav taws xob los ntawm biomass zog-carbon capture (BECCS) thev naus laus zis thiab huab cua carbon capture (DACCS) thev naus laus zis yuav txo qis tag nrho cov nqi peev ntawm cov tshuab coj los ntawm kev sib tshuam txuas ntxiv zog thiab lub zog cia los ntawm 37% mus rau 48. %. Ntawm qhov tod tes, CCUS tuaj yeem txo qhov kev pheej hmoo ntawm cov khoom muaj nqis thiab txo cov nqi zais. Siv CCUS thev naus laus zis los hloov pauv cov kev lag luam muaj feem cuam tshuam tuaj yeem paub txog kev siv cov pa roj carbon tsawg ntawm cov pob txha siv hluav taws xob thiab txo cov nqi ntawm cov chaw nyob rau hauv qhov txwv ntawm carbon emissions.
