Ntambama yangomhla ziyi-14 kuZibandlela, i-China Baowu, i-Rio Tinto kanye neNyuvesi yaseTsinghua ngokuhlanganyela baba nomhlangano wesi-3 we-China Steel Low Carbon Development Goals and Pathways Workshop ukuze kuxoxwe ngomgwaqo oya ekuguquleni ikhabhoni ephansi embonini yensimbi.
Selokhu ukukhiqizwa kweqa amathani ayizigidi eziyi-100 ngo-1996, iChina ibe yizwe elihamba phambili emhlabeni ngokukhiqiza insimbi iminyaka engama-26 ilandelana.I-China iyisikhungo sokukhiqiza semboni yensimbi emhlabeni kanye nesikhungo sokusebenzisa imboni yensimbi emhlabeni.Lapho iChina ibhekene nethagethi yekhabhoni ephindwe kabili yama-30-60, imboni yensimbi iphinde ikhuthaze ukusungulwa kwekhabhoni ephansi eluhlaza, lapho ukuhlela kwesayensi, ukusebenzisana kwezimboni, ukuphumelela kokusungulwa kwezobuchwepheshe kanye nokwenza ngcono ukonga kwamandla konke kubalulekile.
Imboni yensimbi ingafinyelela kanjani i-peak carbon and carbon neutrality?
Njengemboni ebalulekile eyisisekelo emnothweni kazwelonke, imboni yensimbi nayo ingelinye lamaphuzu abalulekile nobunzima ekukhuthazeni ukuncishiswa kokungcoliswa komoya.U-Wang Hao, iPhini likaMqondisi we-Carbon Summit kanye ne-Carbon Neutral Promotion Division yoMnyango Wezemvelo Yekhomishana Yezokuthuthukiswa Nenguquko Kazwelonke, uveze emhlanganweni ukuthi imboni yensimbi akufanele ifinyelele phezulu ukuze ifinyelele phezulu, ingasaphathwa eyokunciphisa ukukhiqiza ngenxa yokunciphisa ukungcola, kodwa kufanele kuthathwe isiqongo sekhabhoni njengethuba elibalulekile lokugqugquzela uguquko lwekhabhoni eluhlaza nephansi kanye nokuthuthukiswa kwezinga eliphezulu kwemboni yensimbi.
U-Huang Guiding, iphini likanobhala-jikelele we-China Iron and Steel Industry Association, uthe emhlanganweni ukuze kugqugquzelwe i-green and low-carbon, imboni yensimbi yaseChina igqugquzela ngenkuthalo amaphrojekthi amathathu ensimbi amakhulu: ukushintshwa kwamandla, ukukhishwa kwe-ultra-low namandla amakhulu. ukusebenza kahle.Kodwa-ke, insiza kanye namandla aseShayina anikezwa insimbi enganele, ecebile ngamalahle futhi empofu kuwoyela negesi, inquma ukuthi isimo semboni yensimbi yaseChina, ephethwe inqubo ende yokuqhunyiswa kweziko neziguquli, izogcinwa isikhathi eside. isikhathi eside.
U-Huang uthe, ukukhuthazwa okujulile kobuchwepheshe bokonga amandla kanye nokusungulwa kwemishini emisha kanye nokuguqulwa nokuthuthukiswa, yonke inqubo yokuthuthukisa ukusebenza kahle kwamandla, yiyona nto ehamba phambili embonini yensimbi yokunciphisa i-carbon, kodwa futhi isihluthulelo sekhabhoni ephansi yakamuva. ukuguqulwa nokuthuthukiswa kwensimbi yaseChina.
Ngo-Agasti kulo nyaka, iKomidi Lokukhuthaza Umsebenzi Wezimboni Zensimbi Likhiphe ngokusemthethweni “Umbono Ongathathi hlangothi Wekhabhoni kanye Nomgwaqo Wendlela Yobuchwepheshe Bekhabhoni Ephansi Yemboni Yensimbi” (kamuva ebizwa ngokuthi “Imephu Yomgwaqo”), ecacisa izindlela eziyisithupha zobuchwepheshe zokuguqulwa kwekhabhoni ephansi. yemboni yensimbi yaseShayina, okuwukuthi uhlelo lokuthuthuka kokusebenza kahle kwamandla, ukugaywa kabusha kwezinsiza, ukwenziwa ngcono kwenqubo kanye nokusungula izinto ezintsha, ukuphumelela kwenqubo yokuncibilikisa, ukuphindaphinda nokuthuthukiswa komkhiqizo, kanye nokubanjwa kwekhabhoni kanye nokusetshenziswa kokugcina.
I-Roadmap ihlukanisa inqubo yokusebenzisa uguquko lwekhabhoni embaxambili embonini yensimbi yaseChina ibe yizigaba ezine, isigaba sokuqala esokugqugquzela impumelelo engaguquki yokunyuka kwekhabhoni ngo-2030, i-decarbonization ejulile kusukela ngo-2030 kuya ku-2040, ukugijimela ukwehlisa ikhabhoni ngokwedlulele kusukela ngo-2030 kuya ku-2040. 2040 kuya ku-2050, kanye nokukhuthaza ukungathathi hlangothi kwekhabhoni kusuka ku-2050 kuya ku-2060.
UFan Tiejun, umongameli weMetallurgical Industry Planning and Research Institute, uhlukanise ukuthuthukiswa kwemboni yensimbi yaseChina kwaba yizinkathi ezimbili nezigaba ezinhlanu.Lezi zikhathi ezimbili yinkathi yenani kanye nesikhathi sekhwalithi ephezulu, isikhathi senani sihlukaniswa ngesigaba sokukhula kanye nesigaba sokunciphisa, futhi isikhathi sekhwalithi ephezulu sihlukaniswa ngesigaba sokusheshisa sokuhlelwa kabusha, isigaba esiqinisiwe sokuvikelwa kwemvelo kanye nokuthuthukiswa kwekhabhoni ephansi. esiteji.Ngokubona kwakhe, imboni yensimbi yaseShayina njengamanje isesigabeni sokuncishiswa, isheshisa isigaba sokuhlela kabusha futhi iqinisa isigaba sokuvikelwa kwemvelo sesikhathi esidlulela izigaba ezintathu.
U-Fan Tiejun uthe, ngokokuqonda nokucwaninga kweMetallurgical Planning and Research Institute, imboni yensimbi yaseChina isivele isishiyile isigaba semiqondo engacacile neziqubulo ezingenalutho, futhi amabhizinisi amaningi aseqalile ukusebenzisa izinhlelo ze-carbon double action emsebenzini obalulekile wensimbi. amabhizinisi.Inqwaba yezigayo zensimbi zasekhaya seziqalile ukuzama i-hydrogen metallurgy, amaphrojekthi e-CCUS kanye namaphrojekthi kagesi aluhlaza.
Ukusetshenziswa kwensimbi ye-Scrap kanye ne-hydrogen metallurgy kuyizinkomba ezibalulekile
Abangaphakathi embonini baveza ukuthi ohlelweni lokuguqulwa kwekhabhoni ephansi embonini yensimbi, ukusetshenziswa kwezinsiza zensimbi ezilahliwe kanye nokuthuthukiswa kobuchwepheshe be-hydrogen metallurgy kuzoba ngenye yezinkomba ezimbili ezibalulekile zokuphumelela ekunciphiseni ikhabhoni embonini.
U-Xiao Guodong, umsizi wemenenja jikelele ye-China Baowu Group kanye nommeleli omkhulu we-Carbon Neutral, uveze emhlanganweni ukuthi insimbi iyimpahla eluhlaza egaywa kabusha futhi imboni yensimbi ibe yisisekelo esibalulekile sokusekela ukuthuthukiswa komhlaba wesimanje.Izinsiza zensimbi ezilahliwe emhlabeni wonke azanele ukuhlangabezana nezidingo zentuthuko yezenhlalakahle, futhi ukukhiqizwa kwensimbi kusukela ensimbi kuyohlala kuyinsakavukela isikhathi eside esikhathini esizayo.
UXiao uthe ukuthuthukiswa kokukhiqizwa kwemikhiqizo yensimbi enekhabhoni ephansi nensimbi akunqunywa kuphela yizimo zamanje zensiza namandla, kodwa futhi ukubeka isisekelo sezizukulwane ezizayo ukuze zikwazi ukuba nezinto eziningi zokugaywa kabusha kwensimbi.Ukuze kuzuzwe umgomo wekhabhoni kabili wemboni yensimbi, ukulungiswa kwesakhiwo samandla kubaluleke kakhulu, lapho amandla e-hydrogen azodlala indima ebalulekile.
UMnu. Huang, iPhini likaNobhala Jikelele we-China Steel Association, uveze ukuthi i-hydrogen metallurgy ingakwazi ukuvala amathuba ezinsizakusebenza ezilahliwe ezinganele emazweni asathuthuka, ikakhulukazi emazweni afana neChina, kanti ukuncishiswa kwe-hydrogen okuqondile kwe-iron kungaba inketho ebalulekile yokuhlukanisa. kanye nokucebisa izinsiza zensimbi ezinqubweni zokugeleza okufushane.
Engxoxweni eyedlule ne-21st Century Business Herald, u-Yanlin Zhao, inhloko yocwaningo lwaseChina e-Bank of America Securities, uthe insimbi iyimboni ekhipha ikhabhoni ephezulu kakhulu ngaphandle kwamandla ashisayo, kanti i-hydrogen, njengomthombo wamandla oguqulekayo, ine-carbon. ithuba elikhulu lokushintsha amalahle namalahle esikhathini esizayo.Uma iphrojekthi ye-hydrogen esikhundleni samalahle ingasetshenziswa ngempumelelo futhi kabanzi ekukhiqizeni izigayo zensimbi, izoletha impumelelo enkulu kanye nethuba elihle lokuthuthukiswa kokuguqulwa kwekhabhoni ephansi embonini yensimbi.
Ngokusho kuka-Fan Tiejun, i-carbon peak embonini yensimbi iyinkinga yentuthuko, futhi ukuze kuzuzwe i-carbon peak esimeme nesayensi embonini yensimbi, into yokuqala okufanele ixazululwe ukulungiswa kwesakhiwo ekuthuthukisweni;ngenkathi isesiteji sokunciphisa i-carbon, ubuchwepheshe obuthuthukisiwe kufanele busetshenziswe ngendlela ehlelekile, futhi isigaba se-decarbonization kufanele sibe nokuvela kobuchwepheshe bezinguquko, okuhlanganisa i-hydrogen metallurgy, kanye nokusetshenziswa okukhulu kwenqubo yokwenza insimbi yesithando somlilo kagesi;esigabeni se-carbon neutral embonini yensimbi, kuyadingeka ukuba Isiteji se-carbon neutral semboni yensimbi kufanele sigcizelele ukuhlangana kwezifunda kanye nezigwegwe eziningi, ukuhlanganisa inqubo yendabuko emisha, i-CCUS kanye nokusetshenziswa kwamasinki e-carbon yehlathi.
Umlandeli u-Tiejun uphakamise ukuthi ukuguqulwa kwekhabhoni ephansi embonini yensimbi kufanele kuhlanganiswe nokuhlelwa kwentuthuko, izidingo zamaketango emboni ekhuphuka nomfula, ukuthuthukiswa kwamadolobha, kanye nokusha kwezobuchwepheshe, nokuthi njengoba imboni yensimbi izofakwa maduze kukhabhoni. emakethe, imboni kufanele futhi ihlanganise imakethe yekhabhoni ukuze ikhuthaze ukongiwa kwamandla kanye nokunciphisa ukungcola ngokombono ogxile emakethe.
