Yakadzika Seabed Minerals haigone Kutsigira Shanduko yeGreen: Chikamu 1

Makambani emigodhi ari kusundira kukadzika kwegungwa migodhi (DSM) sezvinodiwa kune shanduko yakasvibira. Vane chinangwa chekuchera zvicherwa zvakaita secobalt, mhangura, nickel nemanganese vachiti zvicherwa izvi zvinodiwa mukurwisa kusanduka kwemamiriro ekunze pamwe nekuenda kuhupfumi hwakaderera. 

Muchokwadi, rondedzero iyi inoedza kutiratidza kuti kukuvadzwa kusingadzoreki kune zvakasiyana-siyana zvepasi pegungwa chinhu chakaipa chinodiwa munzira yekubvisa carbonization. Motokari yemagetsi (EV), bhatiri, uye vagadziri vemagetsi; hurumende; uye vamwe vakatarisa pakuchinja kwesimba vachiwedzera kusabvumirana. Pane kudaro, kuburikidza nehunyanzvi uye mibatanidzwa yekugadzira, vari kugadzira nzira iri nani: Matanho achangoburwa mukuvandudzwa kwebhatiri anoratidza kufamba kubva pakuchera zvicherwa zvegungwa zvakadzika, uye kuenda kukusimudzira hupfumi hwakatenderedza hunokunda kutsamira kwepasirese kumigodhi yepasi. 

Kufambira mberi uku kuri kuitika pamwe chete nekukura kwekuziva kuti shanduko yesimba yakasimba haigone kuvakwa nemutengo wekuburitsa indasitiri yezvekuwedzera, yakagadzirira kuparadza isinganzwisisike ecosystem yepasi (yakadzika gungwa) uku ichikanganisa masevhisi akakosha ainopa. Sangano reUnited Nations Environment Programme Finance Initiative (UNEP FI) rakaburitswa mharidzo ye2022 - yakanangidzirwa kune vateereri muchikamu chezvemari, semabhangi, mainishuwarenzi, uye vanoisa mari - pane zvemari, zvipenyu, uye dzimwe njodzi dzekuchera kwakadzika kwemakungwa. Chirevo ichi chinopedzisa "hapana nzira inofanoona iyo mari yemabasa emigodhi yemvura yakadzika-mugungwa inogona kuonekwa seinoenderana ne Sustainable Blue Economy Finance Principles.” Kunyangwe The Metals Company (TMC), mumwe wevanosimudzira DSM vatsigiri, anobvuma kuti matekinoroji matsva anogona kusada zvicherwa zvakadzika mugungwa, uye kuti mutengo weDSM unogona. kutadza kupembedza mabasa ekutengeserana. 

Nemaziso akaiswa pane ramangwana rehupfumi rakasvibirira, hunyanzvi hwekuvandudza tekinoroji huri kugadzira nzira yekuchinja kwakasimba pasina yakadzika yegungwa zvicherwa kana njodzi dzirimo muDSM. Isu takaisa pamwechete matatu-zvikamu blog nhevedzano, tichiratidza kufambira mberi uku mumaindasitiri akasiyana.

Battery innovation iri kupfuura kudiwa kwezvicherwa zvegungwa zvakadzika

Battery tekinoroji iri kubuda uye kuchinja musika, nehunyanzvi izvo haidi kana nickel shoma kana cobalt: maviri emaminerari vangave varimigodhi vaizoedza kubva pasi pegungwa. Kuderedza kuvimba uye kudiwa kwezvicherwa izvi kunopa nzira yekudzivirira DSM, kudzikisira zvicherwa zvepasi, uye kumisa kunetsa kwe geopolitical mineral. 

Makambani ari kutoisa mari mune mamwe mabhatiri echinyakare nickel- uye cobalt, achivimbisa nzira nyowani dzekuwana mhedzisiro iri nani.

Semuenzaniso, Clarios, mutungamiri wepasi rose muhunyanzvi hwemabhatiri, akabatana neNatron Energy Inc. kuti abudise mabhatiri e-sodium-ion. Sodium-ion mabhatiri, ari kuwedzera mukurumbira mamwe mabhatiri e lithium-ion, haina zvicherwa kufanana necobalt, nickel, kana mhangura. 

Vagadziri veEV vari kushandisa zvakare matekinoroji matsva kuderedza kudiwa kwavo kwezvicherwa zvepasi pegungwa.

Tesla parizvino anoshandisa lithium iron phosphate (LFP) bhatiri muModel Y neModel 3 mota dzese, dzisingadi nickel kana cobalt. Saizvozvo, nhamba yenyika 2 yemagetsi ekugadzira mota, BYD, yakazivisa zvirongwa kuenda kumabhatiri eLFP uye kure ne nickel-, cobalt-, uye manganese (NCM)-yakavakirwa mabhatiri. SAIC Motors yakagadzira iyo yekutanga yepamusoro-yekupedzisira hydrogen cell based EVs muna 2020, uye muna June 2022, UK-based kambani Tevva yakatanga yekutanga hydrogen cell powered yemagetsi rori. 

Kubva kune vanogadzira mabhatiri kuenda kune vagadziri veEV, makambani ari kuita mafambiro ekudzikisa kunofungidzirwa kuvimba nezvicherwa, kusanganisira izvo zvinobva mugungwa rakadzika. Nenguva iyo vaizove varimigodhi vaigona kuunza zvinhu kubva pakadzika - izvo zvavanobvuma zvinogona kunge zvisingagoneke nehunyanzvi kana mune zvehupfumi – tingasada chimwe chazvo. Nekudaro, kuderedza kushandiswa kwemaminerari aya chingori chidimbu chimwe chete chepuzzle.
