CCUS thev naus laus zis yog qhov kev txhim kho tshiab ntawm Carbon Capture and Storage (CCS) thev naus laus zis, uas yog, carbon dioxide tawm hauv cov txheej txheem tsim khoom yog huv si thiab muab tso rau hauv cov txheej txheem tsim khoom tshiab, uas tuaj yeem siv rov ua dua tshiab tsis yog khaws cia yooj yim.
Piv nrog rau CCS, nws tuaj yeem rov ua dua cov pa roj carbon dioxide, tsim cov txiaj ntsig kev lag luam, thiab siv tau ntau dua.Yog li, rau hom tshiab ntawm lub zog, uas tuaj yeem tsis tsuas yog rov ua dua tshiab, tab sis kuj rov siv cov khoom siv carbon dioxide, los tsim cov txiaj ntsig kev lag luam tshiab, vim li cas thiaj li yog scale ntawm kev loj hlob thiaj li txwv?
I. Kev siv hluav taws xob siab
Peb paub tias cov xwm txheej ntawm cov pa roj carbon dioxide xav tau kev kub hnyiab, tam sim no yog cov khoom siv hluav taws xob siv hluav taws xob ntau tshaj plaws ntawm cov thee, cov hluav taws xob hluav taws xob tsim muaj peev xwm, yuav tso tawm ntau cov pa roj carbon dioxide, tab sis vim tias cov khoom tseem ceeb ntawm cov thee tsis yog xwb. lub C, kuj muaj cov muaj pes tsawg leeg xws li O, S, N, ua rau cov pa roj carbon dioxide purification los ua ib qho ntawm cov txheej txheem kev siv hluav taws xob ntxiv, ntau lub lag luam vim muaj teeb meem, Daim ntawv thov ntawm CCUS technology raug tso tseg.
2,High kos
CCUS thev naus laus zis tau muab faib ua ob theem: carbon dioxide capture thiab carbon dioxide cia. Cov txheej txheem nyuaj ua rau muaj kev nqis peev ntau dhau rau theem pib.
3. High tsis paub tseeb
Tsav los ntawm lub hom phiaj ntawm "carbon neutrality", thev naus laus zis tau dhau los ua lub ntsiab lus uas yuav tsum tau nkag siab hauv kev lag luam. Txawm li cas los xij, qhov tsis muaj kev txhawb siab los ntawm lub teb chaws cov cai thiab cov teeb meem hauv kev sib koom ua lag luam hauv kev lag luam ua rau ntau lub lag luam tsis tuaj yeem txiav txim siab seb lub tshuab puas ua tau, thiab tsis muaj leej twg xav poob nyiaj lawv tau nqis peev.
Tuam Tshoj Lub Txheej Txheem 21 Lub Chaw Tswj Xyuas thiab Tuam Tshoj Lub Koom Haum rau Kev Txhim Kho Kev Txhim Kho tau tsis ntev los no tau tuav ob lub CCUS Young Scholars salons thiab Tuam Tshoj CCUS Demonstration Project Exchange seminars. Nyob rau lub sijhawm ntev, nws yog qhov tsis txaus ntawm cov txuj ci. Nyob rau hauv lub sij hawm ze, nws xav tau ib tug loj thawb los ntawm cov departments.
Nyob rau hauv 2011, thawj version ntawm CCUS Technology Development Roadmap npaj los ntawm Ministry of Science thiab Technology positioned CCUS raws li ib tug "tseem ceeb cia technology" rau loj-scale low-carbon siv fossil zog. Txawm li cas los xij, CCUS thev naus laus zis yog "tsis tseem ceeb" raws li lub hom phiaj ntawm "carbon neutrality". CCUS thev naus laus zis tau lees paub zoo los ntawm Pawg Saib Xyuas Kev Nyab Xeeb Kev Nyab Xeeb Kev Ua Haujlwm ntawm Lub Tsev Haujlwm rau Kev Txhim Kho Kom Zoo. Lawv ntseeg tias CCUS yuav ua plaub lub luag haujlwm tseem ceeb: 1. Nws yog ib qho tseem ceeb ntawm kev xaiv thev naus laus zis rau qhov seem fossil zog net xoom emissions hauv qab carbon neutrality; 2. Nws yog ib qho tseem ceeb sib tw txuj ci kev lag luam thermal fais fab kev lag luam; 3. Nws yog ib qho ntawm ob peb txoj kev daws teeb meem kom ua tiav net xoom emissions hauv kev lag luam uas nyuaj los txo cov emissions, xws li steel thiab cement; 4. Nws yog lub hauv paus tseem ceeb ntawm cov pa roj carbon monoxide rau yav tom ntej lub zog thiab cov txheej txheem tshuaj lom neeg. Nyob rau tib lub sijhawm, los ntawm 2060, qee lub tsev cog khoom gases uas tsis tuaj yeem txo tau yuav tsum tau offset los ntawm cov pa roj carbon dab dej thiab cov thev naus laus zis tsis zoo. Qhov tsis zoo emission thev naus laus zis ua ke nrog CCUS thiab lub zog tshiab yog kev lees paub txog kev ua tiav cov pa roj carbon nruab nrab.
