Izinkampani ezinkulu zensimbi zenze ucwaningo ngazwi linye ngenkuthalo emikhakheni emisha ehlobene namandla futhi zenza izinguquko zokwabiwa kwempahla ukuze kuhlangatshezwane nezidingo zokuthuthukiswa kwemboni yensimbi ezingenayo ikhabhoni eningi.
I-FMG igxile ekushintsheni kwayo kwe-carbon ephansi ekushintsheni imithombo yamandla emisha. Ukuze kufezwe imigomo yenkampani yokunciphisa ukukhishwa kwe-carbon, i-FMG isungule ngokukhethekile inkampani engaphansi kwe-FFI (Future Industries Company) ukuze igxile ekuthuthukisweni kwamandla kagesi aluhlaza, amandla e-hydrogen aluhlaza kanye namaphrojekthi amandla e-ammonia aluhlaza. U-Andrew Forester, uSihlalo we-FMG, uthe: “Umgomo we-FMG ukudala izimakethe zokuhlinzeka kanye nesidingo samandla e-hydrogen aluhlaza. Ngenxa yokusebenza kahle kwamandla aphezulu kanye nokungabi nomthelela emvelweni, amandla e-hydrogen aluhlaza kanye nogesi oluhlaza oqondile i-Energy inamandla okufaka esikhundleni samafutha angaphansi komhlaba ngokuphelele ochungechungeni lokuhlinzeka.”
Engxoxweni eku-inthanethi nentatheli evela e-China Metallurgical News, i-FMG ithe inkampani ihlola ngenkuthalo ikhambi elingcono kakhulu le-hydrogen eluhlaza ukuze kuncishiswe ngempumelelo ukukhishwa kwe-carbon dioxide enkambisweni yokwenza insimbi ngocwaningo kanye nokuthuthukiswa kwamaphrojekthi ensimbi eluhlaza. Njengamanje, amaphrojekthi ahlobene nenkampani afaka ukuguqulwa kwe-iron ore ibe yinsimbi eluhlaza ngokuguqulwa kwe-electrochemical ngaphansi kwezimo zokushisa eziphansi. Okubaluleke kakhulu, ubuchwepheshe buzosebenzisa ngqo i-hydrogen eluhlaza njenge-ejenti yokunciphisa ukuze kuncishiswe ngqo i-iron ore.
I-Rio Tinto iphinde yamemezela embikweni wayo wakamuva wokusebenza kwezezimali ukuthi inqume ukutshala imali kuphrojekthi ye-Jadal lithium borate. Ngaphansi kwesisekelo sokuthola zonke izimvume ezifanele, izimvume namalayisense, kanye nokunaka okuqhubekayo komphakathi wendawo, uhulumeni waseSerbia kanye nomphakathi womphakathi, i-Rio Tinto izibophezele ekutshaleni imali eyizigidigidi ezingama-US $2.4 ukuthuthukisa lo msebenzi. Ngemva kokuba lo msebenzi usuqalile ukusebenza, i-Rio Tinto izoba ngumkhiqizi omkhulu we-lithium ore eYurophu, isekela izimoto zikagesi ezingaphezu kwesigidi minyaka yonke.
Eqinisweni, iRio Tinto isivele inohlelo lwezimboni maqondana nokunciphisa ukukhishwa kwekhabhoni ephansi. Ngo-2018, iRio Tinto yaqeda ukudayisa izimpahla zamalahle futhi yaba yinkampani enkulu kuphela yezimayini yamazwe ngamazwe engakhiqizi uphethiloli. Ngonyaka ofanayo, iRio Tinto, ngokusekelwa kokutshalwa kwezimali kukaHulumeni waseQuebec waseCanada kanye ne-Apple, yasungula i-ElysisTM joint venture ne-Alcoa, eyathuthukisa izinto ze-anode ezingasebenzi ukuze kuncishiswe ukusetshenziswa nokusetshenziswa kwezinto ze-carbon anode, ngaleyo ndlela kuncishiswe ukukhishwa kwekhabhoni dioxide.
I-BHP Billiton iphinde yadalula embikweni wayo wakamuva wokusebenza kwezezimali ukuthi inkampani izokwenza uchungechunge lwezinguquko zamasu kuphothifoliyo yayo yempahla kanye nesakhiwo senkampani, ukuze i-BHP Billiton ikwazi ukuhlinzeka kangcono ngezinsiza ezibalulekile zokukhula okusimeme kanye nokwehliswa kwe-carbonization emnothweni womhlaba.
