– Izitshalo zamandla kagesi ezincane (i-micro-hydro): zifanelekela izindawo ezikude ezinemifudlana yemifula eqinile.
– I-Biomass kanye ne-biogas: izinjini zokushisa noma amajeneretha asekelwe ku-biogas asebenzisa imfucuza yezinto eziphilayo (umquba wezilwane, imfucuza yasekhishini, imfucuza yezolimo) ukukhiqiza amandla.
– Iphampu yokushisa: ubuchwepheshe bokudlulisa ukushisa obusebenza kahle bokushisa noma ukupholisa amakamelo, okungabizi kakhulu kunezifudumezi ezisebenzisa ukushisa.
Ngokuthakazelisayo, imishini eluhlaza akudingeki ukuthi ibe "mikhulu ngaso sonke isikhathi." Amaphaneli elanga, isibonelo, awanazo izingxenye ezihambayo, kodwa adinga izingxenye ezisekelayo ezifana nama-inverter, amabhethri, nezinhlelo zokuphatha amandla ezenzelwe ukusebenza kahle nokuqina.
Ubuchwepheshe Be-Hybrid kanye Namafutha Ahlukile
Kweminye imikhakha, ukufakwa kukagesi okugcwele akuvamile ukuba wusizo. Yilapho ubuchwepheshe bokushintsha bungena khona:
– Injini ye-hybrid: ihlanganisa injini yokushisa kanye nenjini kagesi ukunciphisa ukusetshenziswa kukaphethiloli, ikakhulukazi ezimweni zokuma nokuhamba.
– Ama-biofuel: njenge-biodiesel kanye ne-bioethanol, anganciphisa ukuncika kuphethiloli, yize kusadingeka ukuqinisekisa ukuthi uchungechunge lokuhlinzeka alulimazi amahlathi noma izitshalo zokudla.
– I-hydrogen: ingasetshenziswa ngamaseli kaphethiloli noma ukushiswa kwe-hydrogen. Amandla amakhulu e-hydrogen atholakala ekukhishweni kwayo kwegesi endaweni yokusetshenziswa (amanzi), kodwa ukukhiqizwa kwe-hydrogen kumele kube "luhlaza" (kusuka emandleni avuselelekayo) ukuze kube nobungane bemvelo ngempela.
Inketho ngayinye inezinselele zayo: izindleko, ingqalasizinda, ukuphepha, kanye nokusebenza kahle. Ngakho-ke, amasu omshini oluhlaza ngokuvamile ahlanganisa izixazululo eziningi ezenzelwe izidingo zendawo.
Ukukhiqizwa Okuhlanzekile: Imishini Eluhlaza Embonini
Imishini eluhlaza ayigcini nje ngomkhiqizo wokugcina, kodwa futhi nendlela ekhiqizwa ngayo. Izimboni zinganciphisa umthelela wazo kwezemvelo ngokuthi:
– Uhlelo lokubuyisa ukushisa okungcolile: ukushisa okungcolile okuvela ezithandweni noma kuma-boiler kungasetshenziswa kabusha ekufudumaleni noma ekukhiqizeni ugesi.
– Ukuzenzakalela okuhlakaniphile kanye nezinzwa (IIoT): ukuqapha ngesikhathi sangempela kusiza ukunciphisa imfucuza yamandla, ukuthola ukuvuza, kanye nokuthuthukisa ukulungiswa okubikezelayo.
– Idizayini ye-Modular nelula ukuyilungisa: imishini elula ukuyilungisa yandisa isikhathi sesevisi futhi inciphisa imfucuza.
Ngaphezu kwalokho, ukusetshenziswa kwezimiso zokukhiqiza ezingenamsoco kanye nokunciphisa amaphutha okukhiqiza kusho futhi ukunciphisa izinto ezilahlwayo kanye namandla alahlwayo.
Ukuphathwa Kwemfucuza Nokusetshenziswa Kabusha
Ubuchwepheshe benjini eluhlaza busho nokucabangela ukuphela kokuphila komkhiqizo. Izinjini, amabhethri, kanye nezingxenye ze-elekthronikhi zinamandla okuba yimfucuza eyingozi uma zingaphathwa kahle. Izixazululo ezivelayo zifaka:
– Umklamo wokuqaqa: izingxenye zihlukaniswa kalula ukuze ziphinde zisetshenziswe.
– Ukuvuselela izinsimbi nezinto ezibiza kakhulu: njenge-aluminium, ithusi kanye nezinsimbi zomhlaba ezingavamile.
– Ukucutshungulwa kwamabhethri: amabhethri ezimoto zikagesi adinga uhlelo lokuvuselela kabusha nokusebenzisa kabusha (impilo yesibili) ukuze angabi umthwalo wemvelo.
Ngomjikelezo ovaliwe (umnotho ojikelezayo), umthwalo wokukhipha izinsiza ezintsha ungancishiswa.
Umthelela Omuhle Emvelweni Nasemphakathini
Uma isetshenziswa kabanzi, ubuchwepheshe bezinjini eziluhlaza buhlinzeka ngezinzuzo zangempela:
1. Ukunciphisa ukukhishwa kwe-CO₂ okubangela ukunciphisa ukuguquka kwesimo sezulu.
