Imboni yensimbi engagqwali idlala indima ebalulekile engqalasizinda yesimanje, ekukhiqizeni, kanye nentuthuko esimeme. Njengoba ingxoxo yomhlaba wonke ishintshela ekunciphiseni izinyathelo zekhabhoni kanye nokulwa nokushintsha kwesimo sezulu, abakhiqizi bensimbi engagqwali bangaphansi kwengcindezi ekhulayo yokuvumelanisa izinqubo zabo, izintambo zokuhlinzeka, kanye nemikhiqizo. Umbuzo othi “Imboni Yensimbi Engagqwali Ibhekana Kanjani Nokushintsha Kwesimo Sezulu?” awugcini nje ngesikhathi kodwa futhi ubalulekile kubaphathi bokuthenga, onjiniyela, kanye nabatshalizimali abafuna izixazululo ezinobungani nemvelo.
Lesi sihloko sihlola indlela imboni yensimbi engagqwali ebhekana ngayo nezinselele zesimo sezulu, ukuthi yimaphi amasu asetshenziswayo, kanye nombono wesikhathi esizayo wokukhiqiza okuluhlaza.
Umthelela Wesimo Sezulu Wokukhiqizwa Kwensimbi Engagqwali
Ukukhiqiza insimbi engagqwali kuyinqubo edinga amandla amaningi encike kakhulu ezintweni zokusetshenziswa ezifana ne-nickel, i-chromium, kanye ne-iron ore. Ngokwesiko, lezi zinqubo zikhiqiza ukukhishwa okukhulu kwe-carbon dioxide ngenxa yalokhu:
-
Ukusetshenziswa kwamandla aphezulungesikhathi sokuncibilikisa nokucwenga.
-
Ukusetshenziswa kwezinto zokubasa ezimbiwa phansiekuncibilikiseni nasekuthuthweni.
-
Ukukhishwa kwemikhiqizo yochungechunge lokuphakelwakusukela ekuvubukuleni nasekucubungulweni kwezinto.
Ngokusho kwemibiko yemboni, imboni yensimbi inikela cishe ku-7-9% wokukhishwa kwe-CO₂ emhlabeni jikelele, okwenza ukususwa kwe-carbonization kube ngenye yezinto eziza kuqala kuyo.
Amasu Ayisihluthulelo Okunciphisa Ukukhishwa Kwegesi
1. Ukushintshela Emandleni Avuselelekayo
Izimboni eziningi zensimbi engagqwali zitshala imali kumandla elanga, omoya, kanye namanzi ukuze kuncishiswe ukuthembela kumalahle kanye negesi yemvelo. Ukusebenzisa amandla avuselelekayo ukunika amandla izitofu zikagesi kuyisinyathelo esibalulekile sokunciphisa ukukhishwa kwegesi.
2. Ukuvuselela kanye Nomnotho Ojikelezayo
Insimbi engagqwaliIngaphinde isetshenziswe ngo-100%, okubeka imboni endaweni engcono uma kuqhathaniswa nezinye izinto zokwakha. Ngokwandisa isilinganiso sensimbi elahliwe ekukhiqizweni, abakhiqizi banciphisa isidingo se-ore eyi-virgin futhi banciphise ukusetshenziswa kwamandla.
3. Ukubanjwa Nokugcinwa Kwekhabhoni (CCS)
Abanye abakhiqizi abaphambili bahlola ubuchwepheshe bokubamba ikhabhoni ukuze babambe ukukhishwa kwegesi ngaphambi kokuba kufinyelele emkhathini. Lokhu kusungula izinto ezintsha kunganciphisa kakhulu umthelela wekhabhoni ekukhiqizweni kwensimbi engagqwali okuyinhloko.
4. I-Hydrogen Eluhlaza Ekwenzeni Insimbi
Ukunciphisa okuqondile okusekelwe ku-hydrogen kuvela njengendlela entsha yokufaka esikhundleni se-coke ezithandweni zokuqhuma. Nakuba kusesesigabeni sayo sokuqala, inikeza indlela yesikhathi eside yokukhiqizwa kwensimbi engagqwali ekhipha ukungcola okuncane.
5. Ukuthuthukiswa Kochungechunge Lokunikezela
Imizamo yokususa i-carbon dioxide ayigcini nje endaweni yokukhiqiza. Izinkampani zinciphisa nokukhishwa kwegesi kwezokuthutha ngokuthola izinto zasendaweni, ukuthuthukisa ezokuthutha, kanye nokubambisana nabaphakeli abaqhubekayo.
Ukubambisana Kwemboni Yonke
Izinhlangano zomhlaba wonke ziyakhiwa ukuze kusheshiswe uguquko oluqhubekayo. Izinhlelo ezifanaInsimbi Enomthwalo WemfanelokanyeIzinhlelo zokuzinza ze-World Stainless Associationukuhlanganisa abaholi bemboni ukuze babeke izindinganiso zemikhuba yokulondoloza imvelo.
Izinkampani eziningi, okuhlanganisa ne-SAKY STEEL, zihlanganyela nezinhlangano zamazwe ngamazwe ukuqinisekisa ukuthi ziyahambisana ne-CBAM (Carbon Border Adjustment Mechanism) ye-EU kanye neminye imithethonqubo yezemvelo. Ngokufaka ukusimama emikhubeni yokuthenga nokuthumela kwamanye amazwe, abahlinzeki baqinisa isikhundla sabo emakethe yomhlaba wonke.
Indima Yokusungula Izinto Ezintsha Nokwenza Izinto Zibe Yidijithali
Ukusungula izinto ezintsha kwezobuchwepheshe kuyizinto ezibalulekile ezibangela amasu okushintsha kwesimo sezulu ekukhiqizweni kwensimbi engagqwali.
-
Izinhlelo zokuqapha ezisebenzisa i-AIkusiza izigayo ukuthi zithuthukise ukusebenza kwesithando somlilo, kuncishiswe ukusetshenziswa kwamandla okungadingekile.
-
I-Blockchain yamaketanga okuhlinzekakuthuthukisa ukucaca, ukuqinisekisa ukuthi izinto zokusetshenziswa zitholakala ngendlela efanele.
-
Ama-alloy athuthukisiweziyathuthukiswa ngezidingo zamandla eziphansi ekukhiqizweni kanye nokuphila isikhathi eside ekusetshenzisweni, okusekela imigomo yokuzinza.
Imithetho Kahulumeni kanye Nezidingo Zemakethe
Ohulumeni emhlabeni wonke baqinisa amazinga okukhishwa kwegesi futhi bethula izindlela zokubeka amanani e-carbon. Abathengi baqhubeka befuna imikhiqizo yensimbi engagqwali equkethe i-carbon ephansi ezimbonini ezifana nezokwakha, ezimoto, ezokwelapha kanye nezindiza.
Lokhu kushintsha kokulindelekile emakethe kuphoqa abahlinzeki ukuthi bagqamise iziqinisekiso zokusimama kumathenda kanye nezitifiketi. Isibonelo, ukuhlinzeka ngezimemezelo zomkhiqizo wezemvelo ezinemininingwane (ama-EPD) kanye nezitifiketi zokuhlola umshini sekuyinto ejwayelekile.
Indlela Ochwepheshe Bokuthenga Abangazuza Ngayo
Kwabachwepheshe bokuthenga, ukuqonda ukuthi imboni yensimbi engagqwali ibhekana kanjani nokushintsha kwesimo sezulu kubalulekile ekukhetheni abaphakeli kanye nokuhlela iphrojekthi yesikhathi eside. Izinto ezibalulekile okufanele zicatshangelwe zifaka:
-
Ingabe umhlinzeki usebenzisa amandla avuselelekayo?
-
Yiliphi iphesenti lokuqukethwe okuphinde kwasetshenziswa elifakiwe kokuqukethwe?
-
Ingabe umhlinzeki anganikeza idatha ye-carbon footprint noma imibiko yokuthobela imithetho ye-CBAM?
-
Umhlinzeki uqinisekisa kanjani ukuthi izinto ziyaqhubeka nokupakishwa kanye nokuthuthwa?
Ngokubuza le mibuzo, abathengi bavumelanisa izinqumo zabo zokuthenga nezinhloso zesimo sezulu somhlaba wonke.
Izifundo Zezimo: Abaholi Bomhlaba Wonke Ensimbi Engagqwali Eqhubekayo
-
Abakhiqizi baseYurophu: Izimboni eziningana eSweden, eFinland naseJalimane sezivele zisebenza ngokwengxenye kumandla avuselelekayo kanye nokufakwa kwemfucuza ephezulu, okubeka uphawu lokulinganisa kwezinye.
-
Abakhiqizi base-AsiaEmazweni afana neShayina neNdiya, izinkampani zenza izitofu zibe zesimanje futhi zandisa ukuzenzakalela ukuze kuncishiswe ukukhishwa kwegesi.
-
Izinhlelo ze-SAKY STEEL: Njengomhlinzeki wensimbi engagqwali emhlabeni jikelele, i-sakysteel iyaqhubeka nokuhlanganisa ukusimama eketangeni layo lokuhlinzeka, inikeza amakhasimende hhayi nje imikhiqizo esezingeni eliphezulu kodwa futhi nezixazululo ezinakekela imvelo.
Umbono Wesikhathi Esizayo
Indlela eya ensimbini engagqwali engenasici iyinselele kodwa ingafinyeleleka. Iminyaka eyishumi ezayo cishe izobona:
-
Ukwamukelwa kabanzi kokwenziwa kwensimbi ye-hydrogen.
-
Ukusetshenziswa okwengeziwe kwedatha yokuhlola umjikelezo wokuphila (i-LCA) ukuze kube sobala.
-
Ubambiswano phakathi kwezimboni ezahlukene phakathi kwemikhakha yamandla, yezimayini kanye neyensimbi.
-
Ukutshalwa kwezimali okwengeziwe ekuthuthweni nasekupakishweni okungenawo umoya-mpilo.
Lezi zindlela zikhomba ushintsho olukhulu, okuqinisekisa ukuthi insimbi engagqwali ihlala iyitshe lesisekelo sokwakha okusimeme, amandla, kanye nentuthuko yezimboni.
Isiphetho
Ngakho-ke, imboni yensimbi engagqwali ibhekana kanjani nokushintsha kwesimo sezulu? Ngokwamukela amandla avuselelekayo, ukuvuselela kabusha, ubuchwepheshe obusha, kanye nezintambo zokuhlinzeka ezithembekile, imboni iqhubekela phambili ekusaseni elingenayo ikhabhoni eningi.
Kubathengi, lolu shintsho lusho ukufinyelela okukhulu ezintweni ezihlala isikhathi eside ezihlangabezana nemigomo yokusebenza kanye neyokuvikela imvelo. Izinkampani ezifana ne-sakysteel zihola lolu hambo, zibonisa ukuthi insimbi engagqwali esezingeni eliphezulu kanye nomthwalo wemfanelo wesimo sezulu kungahambisana.
Ukulwa nokushintsha kwesimo sezulu kudinga ukuthi yonke imboni ivumelane nezimo, futhi insimbi engagqwali ifakazela ukuthi ngokusungula izinto ezintsha, ukubambisana, kanye nokuzibophezela, ikusasa eliluhlaza lingenzeka.
