Ngekucondziswa lisu le “khabhoni lephindvwe kabili”, timboni letinyenti takhe indlela lecacile yekonga emandla kanye nekunciphisa ikhabhoni. Kufezeka kwekungatsatsi luhlangotsi kwekhabhoni akuhlukaniseki nekusebentisa tebuchwepheshe be-CCUS. Kusetjentiswa lokutsite kwebuchwepheshe be-CCUS kufaka ekhatsi kubanjwa kwekhabhoni, kusetjentiswa kwekhabhoni kanye nekugcinwa, njll Loluchungechunge lwekusebentisa tebuchwepheshe ngekwemvelo lufaka ekhatsi kuhambisana kwemavalvu. Kusukela kumbono wetimboni letihlobene kanye neticelo, intfutfuko yesikhatsi lesitako Litsemba lifanelwe kunakwa kwetfu .ivalvuimboni.
1.CCUS umcondvo kanye nemboni chain
Umcondvo we-A.CCUS
I-CCUS ingahle ingatayeleki nobe ingatayeleki ngisho nebantfu labanyenti. Ngako-ke, ngaphambi kwekutsi sivisise umtselela we-CCUS embonini yevalve, asifundze nge-CCUS ndzawonye. I-CCUS sifinyeto sesiNgisi (Kubanjwa kweKhabhoni, Kusetjentiswa Nekugcina)
B.CCUS imboni umjikeleto.
Lonkhe luhlelo lwemboni ye-CCUS lwakhiwe kakhulu ngetikhonjiso letisihlanu: umtfombo wekukhishwa, kubamba, kutfutsa, kusetjentiswa kanye nekugcina, kanye nemikhicito. Letikhonjiso letintsatfu tekubamba, kutfutsa, kusebentisa kanye nekugcina tihlobene kakhulu nemboni yemavalvu.
2. Umtselela we-CCUS ku .ivalvuimboni
Ngekucondziswa kungatsatsi luhlangotsi kwekhabhoni, kucala kusebenta kwekubamba ikhabhoni kanye nekugcinwa kwekhabhoni ku-petrochemical, emandla ekushisa, insimbi, simende, kushicilela kanye naletinye timboni letiseceleni kwemboni yemavalvu kutawukhula kancane kancane, futsi kutawukhombisa timphawu letehlukene. Tinzuzo talemboni titawukhululwa kancane kancane, futsi kumele sinake kakhulu intfutfuko lefanele. Kufunwa kwemavalvu kuletimboni letisihlanu letilandzelako kutawukhula kakhulu.
A. Sidzingo semboni ye-petrochemical nguso sekucala kugcizelela .
Kulinganiselwa kutsi sidzingo sekunciphisa kukhishwa kwe-petrochemical eveni lami nga-2030 singaba ngemathani latigidzi letingu-50, futsi sitawuncipha kancane kancane sibe ngu-0 nga-2040. kusetjentiswa kwebuchwepheshe be-CUSS kube kwekucala kukhutsatwa kulomkhakha. Nga-2021, i-Sinopec itawucala kwakha umklamo wekucala we-CCUS wemathani latigidzi waseShayina, umklamo we-CCUS we-Qilu Petrochemical-Shengli Oilfield. Ngemuva kwekutsi lephrojekthi seyiphelile, itawuba sikhungo lesikhulu sekubonisa se-CCUS lephelele yemboni eShayina. Idatha leniketwe yi-Sinopec ikhombisa kutsi linani le-carbon dioxide lebanjwe yi-Sinopec nga-2020 selifinyelele kumathani langaba tigidzi letingu-1.3, lapho khona emathani langu-300,000 atawusetjentiselwa tikhukhula tetindzawo temafutsa, lokufeze imiphumela lemihle ekwenteni ncono kukhishwa kwekhabhoni kanye nekunciphisa kukhishwa kwekhabhoni.
B. Sidzingo semboni yemandla lashisako sitawukhula .
Kusukela esimeni lesikhona nyalo, kufuna emavalvu embonini yemandla, ikakhulukati embonini yemandla lashisako, akusiko lokukhulu kakhulu, kepha ngaphansi kwekucindzetelwa kwelisu le “khabhoni lephindvwe kabili”, umsebenti wekunciphisa ikhabhoni yetikhungo temandla letisebentisa emalahle uya ngekuba matima. Ngekuya kwekubiketela kwetikhungo letifanele: sidzingo sagezi eveni lami silindzeleke kutsi sikhuphuke sibe ngema-kWh latigidzigidzi letingu-12-15 ngemnyaka wa-2050, futsi emathani langetigidzigidzi letingu-430-1.64 e-carbon dioxide adzinga kuncishiswa ngebuchwepheshe be-CCUS kute kuzuzwe kukhishwa kwemfutfo lophelele eluhlelweni lwemandla. Uma ngabe sikhungo semandla lesisebentisa emalahle sifakwa nge-CCUS, singabamba 90% wekhabhoni lekhishwako, kwenta kutsi kube bucwepheshe bekukhicita emandla laphansi ekhabhoni. CCUS sicelo yindlela leyinhloko yebuchwepheshe yekucaphela kugucugucuka kweluhlelo lwamandla. Kulesi simo, kufuna emavalvu lokubangelwa kufakwa kwe-CCUS kutawukhula kakhulu, futsi kufuna emavalvu emakethe yemandla, ikakhulukati emakethe yemandla lashisako, kutawukhombisa kukhula lokusha, lokufanele kutsi kunakwe ngemabhizinisi embonini yemavalvu.
C. Sidzingo semboni yensimbi kanye netinsimbi sitawukhula .
Kulinganiselwa kutsi sidzingo sekunciphisa kukhishwa kwemfutfo ngemnyaka wa-2030 sitawuba ngemathani latigidzi letinge-200 kuya kumathani latigidzi letinge-050 ngemnyaka. Kufanele kucashelwe kutsi ngetulu kwekusetjentiswa kanye nekugcinwa kwe carbon dioxide embonini yensimbi, ingaphindze isetjentiswe ngco enchubeni yekwenta insimbi. Kusebentisa ngalokugcwele lobuchwepheshe kungehlisa kukhishwa kwemfutfo nga 5%-10%. Kusukela kulombono, sidzingo sevalve lefanele embonini yensimbi sitawuba netingucuko letinsha, futsi sidzingo sitawukhombisa umkhuba lomkhulu wekukhula.
D. Sidzingo semboni yesimende sitawukhula kakhulu
Kulinganiselwa kwekutsi sidzingo sekunciphisa kukhishwa kwemfutfo nga-2030 sitawuba ngemathani latigidzi leti-100 kuya kumathani latigidzi leti-152 ngemnyaka, kantsi sidzingo sekunciphisa kukhishwa kwemfutfo nga-2060 sitawuba ngemathani latigidzi letingu-190 kuya kumathani latigidzi letinge-210 ngemnyaka. Le carbon dioxide lekhicitwa kubola kwe limestone embonini yesimende ibalelwa ku 60% wekukhishwa lokuphelele, ngako iCCUS yindlela ledzingekako yekususa icarbon embonini yesimende.
E.Sidzingo semboni yemandla e-hydrogen sitawusetjentiswa kakhulu
Kukhipha i-hydrogen leluhlata sasibhakabhaka kusuka ku-methane kugesi wemvelo kudzinga kusetjentiswa kwelinani lelikhulu lemavalvu, ngoba emandla atfunjwa kusuka enchubeni yekukhicita iCO2, kubamba nekugcina icarbon (CCS) kuyadzingeka, futsi kudluliswa kanye nekugcina kudzinga kusetjentiswa kwelinani lelikhulu lemavalvu.
3. Tiphakamiso temboni yevalve .
I-CCUS itawuba nesikhala lesikhulu sekutfutfuka. Nanobe ibhekene nebumatima lobehlukahlukene, ngesikhatsi lesidze, i-CCUS itawuba nesikhala lesibanti sekutfutfuka, lokuyintfo lengabukwa. Imboni yevalve kufanele igcine kuvisisa lokucacile kanye nekulungiselela kwengcondvo lokwenele kwaloku. Kunconywa kutsi imboni yemavalvu isebentise ngenkhutsalo emasimu lahlobene nemboni ye-CCUS .
A. Kuhlanganyela ngenkhutsalo kumaphrojekthi ekubonisa e-CCUS. Kulephrojekthi ye-CCUS lephunyeleliswa eChina, emabhizinisi embonini yemavalvu kumele ahlanganyele ngenkhutsalo ekusebentiseni lephrojekthi ngekwebuchwepheshe kanye nelucwaningo lwemikhicito kanye nekutfutfukisa, afingqa lwati enchubeni yekuhlanganyela ekusebentiseni lephrojekthi, futsi ente emalungiselelo lanele ekukhicita lokukhulu lokulandzelako kanye nekuhambisana kwemavalvu. Buchwepheshe, lithalenta kanye nemikhicito legodliwe.
B. Gcila ekwakhiweni kwemboni lebalulekile ye-CCUS yamanje. Kugcila embonini yemandla emalahle lapho khona bucwepheshe bekubamba ikhabhoni yaseChina busetjentiswa kakhulu, kanye nemboni yaphethroliyamu lapho khona kugcinwa kwemhlaba kugcila khona kute kusetjentiswe emavalvu ephrojekthi ye-CCUS, futsi kusetjentiswe lamavalvu etindzaweni lapho khona letimboni tikhona, njenge-Ordos Basin kanye ne-Junggar-Tuha Basin, lokutindzawo letibalulekile tekukhicita emalahle. I-Bohai Bay Basin kanye ne-Pearl River Mouth Basin, letitindzawo letibalulekile letikhicita oyili negesi, tisungule budlelwane lobusedvute bekubambisana nemabhizinisi lafanele kute kutsatfwe lelitfuba.
C. Kuniketa kusekelwa lokutsite kwetimali kwebuchwepheshe kanye nelucwaningo lwemkhicito kanye nekutfutfukiswa kwemavalvu ephrojekthi ye-CCUS. Kute kuhole emkhakheni wemavalvu emaphrojekthi e-CCUS esikhatsini lesitako, kunconywa kutsi tinkampani temboni tibeke eceleni imali letsite elucwaningweni nasekutfutfukiseni, futsi tinikete lusekelo kumaphrojekthi e-CCUS mayelana nelucwaningo nekutfutfukiswa kwetebucwepheshe, kute kwakhiwe simo lesihle sekuhleleka kwemboni ye-CCUS.
Ngamafuphi, embonini ye-CCUS, kunconywa kutsi .ivalvuimboni ivisisa ngalokuphelele tingucuko letinsha tetimboni ngaphasi kwelisu le “dual-carbon” kanye nematfuba lamasha ekutfutfuka lafika nawo, ihambisane netikhatsi, futsi ifinyelele intfutfuko lensha kulemboni!
