I-lithium, i-cobalt, i-nickel ne-manganese ziphakathi kwezinto ezingavuthiwe eziyinhloko ezakha amabhethri ezimoto zikagesi. Kodwa-ke, eminyakeni yamuva, ngenxa yengcindezi enkulu yokuthuthukisa nokuletha emakethe izimoto eziningi zikagesi, kunengozi yangempela yokuthi azikho izinto zokusetshenziswa zokwenza amabhethri amaningi kangaka.
Udaba olulodwa esike saluhlanganisa ngaphambili - asinawo amandla afakiwe emhlabeni ukuze sikhiphe amanani adingekayo wezinto zokusetshenziswa yenani elilindelekile lezimoto zikagesi, futhi kungathatha iminyaka eminingi ngaphambi kokuba sibe nalo.
NgokweBhange Lomhlaba, isidingo sezinto ezithile esizisebenzisayo ukwenza amabhethri singakhula ngokuphindwe kayi-11 ngo-2050, ngokuphazamiseka kokuhlinzekwa kwe-nickel, i-cobalt nethusi okwabikezelwa ngo-2025.
Ukunciphisa noma ukucindezela isidingo sempahla eluhlaza, kukhona enye indlela. I-DeepGreen Metals, inkampani yezimayini yase-Canadian subsea, iphakamisa njengenye indlela yokumba umhlabathi ukuhlola indawo engaphansi kolwandle, ngokuqondile, i-Pacific Ocean. Kungani iPacific Ocean? Ngoba kulapho, okungenani endaweni eseyinqunyiwe kakade, lapho ukuhlushwa okukhulu Ama-nodule e-polymetallic.
Amaqhuqhuva… ini?
Futhi ebizwa ngokuthi ama-manganese nodules, ama-polymetallic nodules ama-deposit of ferromanganese oxides nezinye izinsimbi, njengalezo ezidingekayo ekukhiqizeni amabhethri. Ubukhulu bawo buhluka phakathi kuka-1 cm no-10 cm - azibukeki ngaphezu kwamatshe amancane - futhi kulinganiselwa ukuthi kungase kube khona amathani ayizigidi eziyizinkulungwane ezingu-500 phansi kolwandle.
Kungenzeka ukuzithola kuzo zonke izilwandle - amadiphozithi amaningana asevele aziwa emhlabeni wonke - futhi atholakale ngisho nasemachibini. Ngokungafani nokukhipha insimbi esekelwe emhlabathini, amaqhuqhuva e-polymetallic atholakala phansi olwandle, ngaleyo ndlela angadingi noma yiluphi uhlobo lomsebenzi wokumba. Ngokusobala, okudingekayo nje… ukukuqoqa.
Yiziphi izinzuzo?
Ngokungafani nokumbiwa komhlaba, ukuqoqwa kwama-nodule e-polymetallic kunenzuzo enkulu nomthelela wayo ophansi kakhulu wemvelo. Lokho kungokocwaningo oluzimele olugunyazwe ngabakwa-DeepGreen Metals, oluqhathanise umthelela wemvelo phakathi kwezimayini zomhlaba kanye nokuqoqwa kwamaqhuqhuva e-polymetallic ukwenza izigidigidi zamabhethri ezimoto zikagesi.

Imiphumela iyethembisa. Ucwaningo lubala ukuthi ukukhishwa kwe-CO2 kwehliswa ngo-70% (i-0.4 Gt isiyonke esikhundleni se-1.5 Gt kusetshenziswa izindlela zamanje), i-94% engaphansi kanye ne-92% engaphansi kwendawo kanye nendawo yamahlathi iyadingeka, ngokulandelana; futhi ekugcineni, akukho imfucuza eqinile kulolu hlobo lomsebenzi.
Lolu cwaningo luphinde luveze ukuthi umthelela ezilwaneni wehle ngo-93% uma uqhathanisa nokumbiwa phansi. Kodwa-ke, i-DeepGreen Metals ngokwayo ithi naphezu kokuba inani lezilwane lilinganiselwe kakhulu endaweni lapho ziqoqwa khona olwandle, iqiniso liwukuthi akukho okuningi okwaziwayo ngezinhlobonhlobo zezilwane ezingahlala lapho, ngakho-ke akunjalo. uyazi ukuthi uyini umthelela wangempela kulesi simiso sezinto eziphilayo. Kuyinhloso ye-DeepGreen Metals ukwenza ucwaningo olunzulu, iminyaka eminingana, ngemiphumela yesikhathi eside emhlabathini wolwandle.
UGerard Barron, i-CEO kanye noMongameli we-DeepGreen Metals"Ukukhishwa kwezinsimbi ezingenalutho kunoma yimuphi umthombo, ngokwencazelo, akugcini futhi kubangela ukulimala kwemvelo. Sikholelwa ukuthi ama-polymetallic nodules ayingxenye ebalulekile yesisombululo. Iqukethe ukugxila okuphezulu kwe-nickel, i-cobalt ne-manganese; ibhethri ngempumelelo imoto kagesi etsheni."
Ngokocwaningo, amaqhuqhuva e-polymetallic akhiwe cishe ngo-100% wezinto ezisetshenziswayo futhi aziwona ubuthi, kuyilapho amaminerali akhishwa emhlabeni anezinga eliphansi lokululama futhi aqukethe izinto ezinobuthi.
Ingabe ikhambi lingaba lapha ukuze sithole izinto zokusetshenziswa zokwenza amabhethri amaningi ngendlela esizoyidinga? I-DeepGreen Metals icabanga kanjalo.

Isifundo: Kufanele Zivelaphi Izinsimbi Zokushintsha Okuluhlaza?
Ithimba likaRazão Automóvel lizoqhubeka ku-inthanethi, amahora angama-24 ngosuku, ngesikhathi sokugqashuka kwe-COVID-19. Landela izincomo zoMqondisi Jikelele Wezempilo, gwema ukuhamba okungenasidingo. Ngokubambisana sizokwazi ukunqoba lesi sigaba esinzima.
