Indima Yensimbi Emandleni Avuselelekayo
Ukushintsha kwesimo sezulu kanye nokuwohloka kwemvelo kuyizinkinga ezimbili ezibaluleke kakhulu zekhulu lama-21. Emzamweni wokunciphisa imiphumela emibi yokusetshenziswa kukaphethiloli, ukunyakaza komhlaba wonke kwamandla avuselelekayo kuyakhula. Imithombo yamandla avuselelekayo njengelanga, umoya, kanye ne-biomass inikeza ezinye izindlela ezihlanzekile nezisimeme. Kodwa-ke, indima yesayensi nobuchwepheshe ekwenzeni lolu shintsho ibe lula ayinakunakwa. Isifundo esisodwa esibalulekile yi-metallurgy, isayensi nobuchwepheshe bokucubungula insimbi.
I-Metallurgy, ehilela ucwaningo olujulile lwezakhiwo zomzimba nezamakhemikhali zezinsimbi kanye nama-alloy, inegalelo elikhulu ekuthuthukisweni kobuchwepheshe bamandla avuselelekayo. Ngezansi, sizochaza ukuthi i-metallurgy idlala kanjani indima ebalulekile emikhakheni eyahlukene yamandla avuselelekayo.
1. Amandla Elanga
Amandla elanga angomunye wemithombo yamandla avuselelekayo ethembisayo kakhulu. Ekuthuthukisweni kwamaphaneli elanga, izinto ezisetshenziswayo zidlala indima ebalulekile. I-Silicon iyinto eyinhloko esetshenziswa kumaseli elanga ngenxa yokusebenza kwayo kahle ekuguquleni ukukhanya kube ugesi. Kodwa-ke, ukusebenza kwe-silicon kuthonywa kakhulu ubumsulwa bayo kanye nesakhiwo sekristalu.
> Indima Yensimbi Ekuhlanjululweni Kwe-Silicon: Insimbi ivumela ukuhlanjululwa kwezinqubo zokuhlanjulwa kwe-silicon ukuze kufezwe amazinga aphezulu kakhulu okumsulwa. Ubuchwepheshe obufana ne-Czochralski kanye nezinqubo ze-floating zone, ezithuthukiswe ngocwaningo lwensimbi, zivumela ukukhiqizwa kwe-silicon enokungcola okuncane, okwandisa kakhulu ukusebenza kahle kwamaphaneli elanga.
Ngaphezu kwalokho, ukusebenza kahle kwamaphaneli elanga kungathuthukiswa ngokuthuthukiswa kwezinto ezintsha ezifana ne-perovskite, into ekhombisa amandla amakhulu okuthuthukisa ukusebenza kahle kokuguqulwa kwamandla elanga. Ukuhlolwa nokukhiqizwa kwe-Perovskite kuncike ezindleleni zensimbi ukuqonda izakhiwo zezinto nokuthi zingathuthukiswa kanjani ukuzinza nokuqina kwazo.
2. Amandla Omoya
Ama-turbine omoya athembele emishinini yemishini okumele ibe namandla, iqine, futhi ikwazi ukusebenza ezindaweni ezinzima. Ama-alloy ensimbi asebenza kahle ayisihluthulelo sokuhlangabezana nalezi zidingo.
> Indima Yensimbi Ekuthuthukisweni Kwe-Alloy: Embonini yamandla omoya, izinto ezifana nensimbi, i-nickel alloys, kanye ne-titanium alloys zivame ukusetshenziswa ezakhiweni nasezingxeni ze-turbine. I-Metallurgy idlala indima ekwakheni i-alloys enezakhiwo ezithuthukisiwe zemishini njengamandla aphezulu okudonswa, ukumelana nokukhathala, kanye nokumelana nokugqwala. Isibonelo, izinsimbi ze-alloy ezisetshenziswa kuma-turbine omoya kumele zikwazi ukumelana nokucindezeleka komoya okuphezulu kanye nemiphumela yokukhathala okujikelezayo.
Ukugcotshwa okusebenzayo nakho kudlala indima ebalulekile ekwandiseni impilo yama-turbine omoya. Ucwaningo olujulile lwe-metallurgical mayelana nokungqubuzana kwensimbi nokuguguleka lungasiza ekudaleni amafutha angcono kanye nezinto ezihlanganisiwe ezingagugi kakhulu ezingandisa impilo yezingxenye ze-turbine, zinciphise izidingo zokulungisa, futhi zinciphise izindleko zokusebenza zizonke.
3. Amandla Okushisa Kwasemoyeni
Amandla okushisa komhlaba ayindlela yobuchwepheshe esebenzisa ukushisa komhlaba ukuze ikhiqize ugesi. Enye yezinselele ezinkulu ekusebenziseni amandla okushisa komhlaba yizimo ezimbi kakhulu okumele imishini namapayipi azibekezelele. Amazinga okushisa aphezulu kanye nokucindezela, kanye nokuba khona koketshezi oluqothulayo, kudinga izinto eziqinile kakhulu.
> Indima Yensimbi Ekukhetheni Nokuthuthukiswa Kwezinto Ezisetshenziswayo: Ama-alloy asekelwe ku-nickel kanye nezinsimbi eziphikisayo zivame ukusetshenziswa ezinhlelweni zamandla e-geothermal ngenxa yokumelana kwawo nokugqwala emazingeni okushisa aphezulu kanye nokucindezela. Insimbi ivumela ukuthuthukiswa kanye nokwenza ngcono kwala ma-alloy ukuze akwazi ukusebenza kangcono futhi isikhathi eside ngaphansi kwezimo ezimbi kakhulu ezitholakala ezinsizeni ze-geothermal.
4. Amandla e-Biomass
Ukushiswa kwe-biomass kukhiqiza amandla ngokuguqula izinto eziphilayo zibe ugesi noma ukushisa. Ukuze kusebenze kahle kakhulu futhi kube nokukhishwa okuncane komoya, izinto zokushiswa kanye neyunithi yokuguqula kumele kwakhiwe ngezinto ezimelana namazinga okushisa aphezulu kanye nokugqwala.
> Indima Yensimbi Ezintweni Ezimelana Nokushisa Nokugqwala: Kuma-incinerator e-biomass, amazinga okushisa okusebenza angaba phezulu kakhulu futhi adale indawo esabela kakhulu. Ngocwaningo lwensimbi, kutholakale ama-alloy akhethekile njenge-alloy esekelwe ku-nickel kanye ne-ceramics ekhethekile engakwazi ukumelana nezimo zokushisa okuphezulu kanye nezindawo ezisabelayo. Lezi zinto zisiza ekuthuthukiseni ukusebenza kahle kwenqubo yokuguqulwa kwamandla nokunciphisa ukukhishwa okuyingozi.
5. Isitoreji Samandla
Ubuchwepheshe bokugcina amandla, njengamabhethri kanye nophethiloli we-hydrogen, buyizinto ezibalulekile ezinhlelweni zamandla avuselelekayo ukuqinisekisa ukuzinza nokuthembeka kokuhlinzekwa kwamandla.
> Indima Yokusetshenziswa Kwensimbi Ekuthuthukisweni Kwezinto Zebhethri: Ukuthuthukisa ukusebenza kwebhethri, ikakhulukazi i-Lithium-ion, kuncike kakhulu ezintweni ze-electrode ezisetshenziswayo. Izinto ze-electrode ezifana ne-cobalt, i-nickel, ne-manganese ziphakathi kwalezo ezithembele kakhulu kubuchwepheshe be-metallurgical ukuthuthukisa ukusebenza kwazo. Ngokuqonda ukusabela kwamakhemikhali kanye nezakhiwo zemishini zalezi zinto, ochwepheshe be-metallurgist bangakha ama-electrode anamakhono okugcina amandla aphezulu, izimpilo zomjikelezo omude, kanye nezikhathi zokushaja ezimfushane.
Ngaphezu kwalokho, ubuchwepheshe be-hydrogen obuhlanganisa ama-electrode ensimbi ukuze kusetshenziswe i-electrolysis yamanzi buzuza kakhulu ocwaningweni lwe-metallurgical. Isibonelo, ukuthola ukwakheka kwe-alloy okuhle kakhulu kwama-electrocatalyst kungathuthukisa ukusebenza kahle kwenqubo ye-electrolysis, okwenza isitoreji kanye nokusetshenziswa kwe-hydrogen njengomthombo wamandla kube wusizo futhi konge imali.
Isiphetho
Kulesi sikhathi sokuguquka kwamandla, ubuchwepheshe bokubumba izinsimbi budlala indima ebalulekile ekuqhubekiseni ukuthuthukiswa kanye nokusetshenziswa kobuchwepheshe bamandla avuselelekayo. Kusukela kumaphaneli elanga kuya kumabhethri e-lithium-ion, impumelelo yalobu buchwepheshe incike kakhulu ekuthuthukisweni kwezinto ezithuthukiswe ngesayensi nobuchwepheshe bokubumba izinsimbi.
Indima ye-metallurgy idlulela ngale kokuthuthukiswa kwezinto ezintsha iye ekuthuthukiseni ukusebenza kahle, ukuqina, kanye nokusebenza kwezinto ezikhona. Ngokuqonda okujulile izakhiwo zezinto kanye namasu okucubungula, i-metallurgy iyaqhubeka nokuvula indlela yezinhlelo zamandla avuselelekayo ezisebenza kahle futhi eziqhubekayo. Ngakho-ke, i-metallurgy iyinsika ebalulekile emizamweni yomhlaba wonke yokufeza imigomo yokuzinza nokubhekana nezinselele zamandla zesikhathi esizayo.
