Ngenjikalanga ye-14 kaDisemba, i-China Baowu, i-Rio Tinto kunye neYunivesithi yaseTsinghua ngokubambisana babambe iinjongo ze-3 ze-China Steel Low Carbon Development Goals kunye ne-Pathways Workshop ukuxoxa ngendlela eya kwinguqu yekhabhoni ephantsi kwishishini lentsimbi.
Ukusukela oko imveliso iqale yadlula kwi-100 lezigidi zeetoni ngo-1996, iTshayina ibe lelona lizwe liphezulu ekuveliseni intsimbi ehlabathini iminyaka engama-26 ilandelelana.I-China liziko lemveliso yoshishino lwentsimbi yehlabathi kunye neziko lokusetyenziswa kweshishini lentsimbi yehlabathi.Kujongwe kwithagethi yekhabhoni ephindwe kabini eTshayina, ishishini lentsimbi likwakhuthaza ukwenziwa kwekhabhoni ephantsi eluhlaza, apho ukucwangciswa kwezenzululwazi, ukusebenzisana kwamashishini, impumelelo entsha yetekhnoloji kunye nophuculo lwamandla ombane zonke zibalulekile.
Ushishino lwentsimbi lunokufikelela njani kwincopho yekhabhoni kunye nokungathathi hlangothi kwekhabhoni?
Njengoshishino olusisiseko olubalulekileyo kuqoqosho lwesizwe, ishishini lentsimbi likwangomnye wamanqaku abalulekileyo kunye nobunzima ekukhuthazeni ukunciphisa ukukhutshwa kwekhabhoni.UWang Hao, uSekela Mlawuli weNgqungquthela yeCarbon kunye neCarbon Neutral Promotion Division yeSebe leMithombo yeNdalo yeKomishoni yoPhuhliso lweSizwe kunye noHlaziyo, wabonisa kwintlanganiso ukuba imboni yensimbi akufanele ifikelele kwincopho ngenxa yokufikelela phezulu. singasathethi ke ukunciphisa imveliso ngenxa yokunciphisa i-emission, kodwa kufuneka ithathe i-carbon peak njengethuba elibalulekileyo lokukhuthaza ukuguqulwa kohlaza kunye nekhabhoni ephantsi kunye nophuhliso oluphezulu loshishino lwentsimbi.
U-Huang Guiding, usekela unobhala jikelele we-China Iron and Steel Industry Association, wathi kwintlanganiso ukuba ukukhuthaza uhlaza kunye nekhabhoni ephantsi, imboni yensimbi yaseChina ikhuthaza iiprojekthi ezintathu ezinkulu zentsimbi: ukutshintshwa kwamandla, ukukhutshwa kwe-ultra-low kunye namandla amakhulu. ukusebenza kakuhle.Nangona kunjalo, ubuncwane baseTshayina kunye namandla okunikezelwa kwesinyithi esilahliweyo esingonelanga, esityebile ngamalahle kwaye sihlwempuzekile kwi-oyile kunye negesi, simisela ukuba imeko yeshishini lentsimbi laseTshayina, elilawulwa yinkqubo ende yeziko lokuqhushumba kunye nabaguquli, liya kugcinwa ixesha elide. xesha elide.
U-Huang uthe, ukukhuthazwa okunzulu kweteknoloji yokulondoloza amandla kunye nokuveliswa kwezixhobo zenkqubo kunye nokuguqulwa nokuphucula, yonke inkqubo yokuphucula ukusebenza kakuhle kwamandla, yinto ephambili yangoku yoshishino lwentsimbi ukunciphisa ikhabhoni, kodwa kwakhona isitshixo kwikhabhoni ephantsi yakutshanje. ukuguqulwa kunye nokuphuculwa kwentsimbi yaseTshayina.
Ngo-Agasti kulo nyaka, iKomidi yokuPhakanyiswa koMsebenzi weNsimbi ephantsi kweCarbon yakhupha ngokusesikweni "iCarbon Neutral Vision kunye neLow Carbon Technology Roadmap yeShishini leNsimbi" (emva koku kuthiwa yi "Roadmap"), ecacisa iindlela ezintandathu zobugcisa zokuguqulwa kwekhabhoni ephantsi. kushishino lwentsimbi yaseTshayina, oko kukuthi, ukuphuculwa kobuchule bokusebenza kwamandla, ukugaywa ngokutsha kwezixhobo, ukuphuculwa kwenkqubo kunye nokuveliswa kwezinto ezintsha, inkqubo yokunyibilikisa, inkqubo yokunyibilikisa, ukuphindaphindwa kwemveliso kunye nokuphuculwa, kunye nokusetyenziswa kwekhabhoni kunye nokusetyenziswa kogcino.
I-Roadmap yahlula inkqubo yokuphumeza inguqu yekhabhoni ephindwe kabini kwishishini lentsimbi yaseTshayina ibe ngamanqanaba amane, inqanaba lokuqala kukukhuthaza ukufezekiswa okuzinzile kwe-carbon peaking ngo-2030, i-decarbonization enzulu ukusuka kwi-2030 ukuya kwi-2040, ukutyhutyha ukuncipha kwekhabhoni egqithileyo ukusuka kwi-2030 ukuya ku-2040. I-2040 ukuya kwi-2050, kunye nokukhuthaza ukungathathi hlangothi kwekhabhoni ukusuka kwi-2050 ukuya kwi-2060.
UFan Tiejun, umongameli weZiko loCwangciso loShishino lweMetallurgical kunye noPhando, wahlulahlula uphuhliso loshishino lwentsimbi lwaseTshayina lube ngamaxesha amabini kunye nezigaba ezihlanu.Amaxesha amabini lixesha lobungakanani kunye nexesha lomgangatho ophezulu, ixesha lobungakanani lihlulwe kwinqanaba lokukhula kunye nenqanaba lokunciphisa, kwaye ixesha lomgangatho ophezulu lihlulwe kwisigaba esikhawulezayo sohlengahlengiso, isigaba sokukhusela indalo esingqongileyo kunye nophuhliso lwekhabhoni ephantsi. iqonga.Ngokombono wakhe, ishishini lentsimbi laseTshayina ngoku likwinqanaba lokuncitshiswa, linyusa isantya sohlengahlengiso kwaye liqinisa isigaba sokhuseleko lokusingqongileyo kwizigaba ezithathu ezidibanayo.
Umlandeli uTiejun uthe, ngokutsho kokuqonda kunye nophando lweMetallurgical Planning and Research Institute, imboni yentsimbi yaseChina sele ishiye inqanaba leengqikelelo ezingacacanga kunye nezilogeni ezingenanto, kwaye uninzi lwamashishini sele luqalisile ukuphumeza amanyathelo aphindwe kabini ekhabhoni kumsebenzi ophambili wentsimbi. amashishini.Inani leentsimbi zasekhaya sele ziqalisile ukuzama i-hydrogen metallurgy, iiprojekthi ze-CCUS kunye neeprojekthi zamandla aluhlaza.
Ukusetyenziswa kwentsimbi ye-Scrap kunye ne-hydrogen metallurgy yimikhombandlela ebalulekileyo
Abangaphakathi kwi-industry babonisa ukuba kwinkqubo yokuguqulwa kwekhabhoni ephantsi yoshishino lwensimbi, ukusetyenziswa kwezixhobo zensimbi ezilahliweyo kunye nophuhliso lweteknoloji ye-hydrogen metallurgy iya kuba yenye yeendlela ezimbini eziphambili zokuphumelela kokunciphisa i-carbon kwishishini.
U-Xiao Guodong, umncedisi womphathi jikelele we-China Baowu Group kunye nommeli oyintloko weCarbon Neutral, wabonisa kwintlanganiso ukuba insimbi yinto eluhlaza enokuphinda isetyenziswe kwaye imboni yensimbi ibe sisiseko esibalulekileyo sokuxhasa uphuhliso lwehlabathi lanamhlanje.Izixhobo zentsimbi ezilahliweyo zehlabathi azanelanga ukuhlangabezana neemfuno zophuhliso loluntu, kwaye imveliso yentsimbi eqala kwintsimbi ekrwada iya kuhlala ingundoqo ixesha elide kwixesha elizayo.
U-Xiao uthe ukuphuhliswa kwe-carbon low-carbon steel kunye nemveliso yeemveliso zentsimbi akunqunywanga kuphela ngumthombo wangoku kunye neemeko zamandla, kodwa ukubeka isiseko kwizizukulwana ezizayo ukuze zibe nezixhobo ezininzi zokuphinda zenziwe ngentsimbi.Ukufezekisa injongo yekhabhoni kabini yoshishino lwensimbi, ukulungiswa kwesakhiwo samandla kubaluleke kakhulu, phakathi kwayo amandla e-hydrogen aya kudlala indima ebalulekileyo.
UMnu. Huang, uSekela Nobhala Jikelele we-China Steel Association, wachaza ukuba i-hydrogen metallurgy inokwenza ukungabikho kobutyebi obunganelanga kumazwe asakhasayo, ngakumbi kumazwe afana ne-China, ngelixa ukucutha i-iron ngokuthe ngqo i-hydrogen ingaba yinto ebalulekileyo yokudibanisa. kunye nokutyebisa ubutyebi bentsimbi kwiinkqubo zokuhamba okufutshane.
Kudliwanondlebe lwangaphambili kunye 21st Century Business Herald, Yanlin Zhao, co-intloko yophando China kwi Bank of America Securities, wathi intsimbi lishishini elinokukhutshwa kwekhabhoni ephezulu ngaphandle kwamandla ashushu, kunye ne-hydrogen, njengomthombo wamandla oguqulwayo ithuba elikhulu lokutshintsha amalahle kunye ne-coke kwixesha elizayo.Ukuba iprojekthi ye-hydrogen endaweni yamalahle inokuthi isetyenziswe ngempumelelo kwaye isetyenziswe ngokubanzi kwimveliso yeentsimbi zetsimbi, iya kuzisa impumelelo enkulu kunye nethuba elihle lophuhliso lokuguqulwa kwekhabhoni ephantsi yoshishino lwensimbi.
Ngokutsho kweFan Tiejun, i-carbon peak kwishishini lensimbi ngumba wophuhliso, kunye nokufezekisa i-carbon ezinzileyo kunye nenzululwazi kwi-industry yensimbi, into yokuqala yokusombulula ukulungiswa kwesakhiwo kuphuhliso;ngelixa kwinqanaba lokunciphisa i-carbon, iteknoloji ephezulu kufuneka isetyenziswe ngokucwangcisiweyo, kwaye isiteji se-decarbonization kufuneka sibe nokuvela kobuchwepheshe be-revolutionary, kubandakanywa ne-hydrogen metallurgy, kunye nesicelo esikhulu sokwenza i-steelmaking yesithando sombane;kwinqanaba lekhabhoni elingathathi hlangothi kwishishini lensimbi, kuyimfuneko ukuba Inqanaba lekhabhoni elingathathi hlangothi kwishishini lensimbi kufuneka ligxininise kwi-cross-regional kunye ne-multi-disciplinary synergy, ukudibanisa inkqubo yemveli entsha, i-CCUS kunye nokusetyenziswa kwe-carbon carbon sinks.
Umlandeli u-Tiejun ucebise ukuba ukuguqulwa kwekhabhoni ephantsi kweshishini lensimbi kufuneka kudityaniswe nokucwangciswa kophuhliso, iimfuno zemixokelelwane yoshishino oluphezulu kunye nolusezantsi, uphuhliso lwedolophu, kunye nokutsha kwezobuchwepheshe, kwaye ekubeni imboni yensimbi iza kufakwa ngokukhawuleza kwikhabhoni. kwimarike, ishishini kufuneka lidibanise imarike yekhabhoni ukukhuthaza ukugcinwa kwamandla kunye nokunciphisa ukukhutshwa kwemveliso kwimbono ejoliswe kwimarike.
