Njengoba kuhlongozwe umgomo “wokukhuphuka kwekhabhoni nokungathathi hlangothi kwekhabhoni”, uguquko olubanzi nolujulile lwezomnotho nezenhlalo seluhamba kahle, olungagcini nje ngokubeka phambili izidingo eziphakeme zokuthuthukiswa kwebhizinisi, kodwa futhi luhlinzeka ngamathuba amakhulu. Ukuphakama kwekhabhoni nokungathathi hlangothi kwekhabhoni kuwudaba oluhlanganisa yonke imboni kanye nenkundla ehlanganisa wonke amabhizinisi. Kumabhizinisi, indlela yokufeza kangcono ukungathathi hlangothi kwekhabhoni kungabhekwa ngale mibono elandelayo:
Yenza ngokuqhubekayo i-carbon accounting nokudalulwa kwekhabhoni
Thola "i-carbon footprint" yakho futhi ucacise ububanzi bokukhishwa kwekhabhoni. Ngesisekelo sokucacisa ububanzi bokukhishwa kwekhabhoni, izinkampani zidinga ukucacisa inani eliphelele lokukhishwa, okungukuthi, ukwenza i-carbon accounting.
Uma bebhekene nokukhethwa kwemikhiqizo efanayo, abathengi banamathuba amaningi okuthi bakhethe imikhiqizo ezinkampanini ezinokukhanya okuphezulu kwebhizinisi nokudalula okusebenzayo komthelela wazo kubantu nasemhlabeni. Ngokwezinga elithile, lokhu kuzogqugquzela izinkampani ukuba zenze ukudalulwa kolwazi olusobala noluqhubekayo, ngaleyo ndlela kuthuthukise ukuncintisana komkhiqizo. Ngaphansi komgomo wokungathathi hlangothi kwekhabhoni, amabhizinisi, njengendikimba eyinhloko yokukhishwa kwekhabhoni, anomthwalo wemfanelo omkhulu wokuqhuba ukulawulwa kwengozi yekhabhoni ephezulu kanye nokudalula ulwazi lwekhwalithi ephezulu.
Amabhizinisi kufanele asungule olwawo uhlelo lokulawula ubungozi bekhabhoni, ahlole ngokuhlelekile ubungozi bekhabhoni, amukele inhlanganisela yokuvimbela, ukulawula, isinxephezelo, ukuzibophezela kanye nokuguqulwa kwamathuba ukuze alawule ubungozi bekhabhoni, ahlole izindleko zokunciphisa ukukhishwa kwekhabhoni, futhi abuyekeze njalo uhlelo lokulawula ubungozi bekhabhoni. Faka ukuphathwa kwengozi yekhabhoni kanye nokuhambisana nekhabhoni kungxube.
Sungula imigomo yesayensi yokunciphisa ukukhishwa kwekhabhoni ngokusekelwe kuzici zebhizinisi. Ngemva kokubala inani lamanje elikhishwa yikhabhoni lebhizinisi, inkampani kufanele izenzele eyayo imigomo nezinjongo zokunciphisa ukukhishwa kwekhabhoni ngokusekelwe ezicini zayo zebhizinisi futhi kuhlanganiswe nezinjongo zezwe lami “ezingama-30·60” zekhabhoni ezimbili. Ukuhlela, nokusebenzisana nokwethulwa kwezindlela ezicacile neziqondile zokusebenzisa ukuncishiswa kwe-carbon peaking kanye nokungathathi hlangothi kwekhabhoni, kuyizimfuneko zokuqinisekisa ukufezwa kwezinjongo endaweni ngayinye yesikhathi esibucayi.
Izinyathelo zobuchwepheshe eziyinhloko zamabhizinisi zokunciphisa ukukhishwa kwekhabhoni zihlanganisa lezi zici ezimbili ezilandelayo:
(1) Ubuchwepheshe bokunciphisa ukukhishwa kwekhabhoni ekushisweni kukaphethiloli
Izinto zokubasa ezisetshenziswa amabhizinisi zihlanganisa amalahle, i-coke, amalahle aluhlaza, uwoyela kaphethiloli, uphethiloli nodizili, igesi ewuketshezi, igesi yemvelo, igesi ye-coke oven, i-coal bed methane, njll. Isici esiyinhloko esithinta ukusetshenziswa kukaphethiloli kanye nokukhishwa kwekhabhoni yinqubo, kodwa kusenobuchwepheshe obuningi bokunciphisa ukukhishwa kwekhabhoni ekuthengeni nasekugcinweni kukaphethiloli, ukucutshungulwa nokuguqulwa, kanye nokusetshenziswa kwetheminali. Isibonelo, ukuze kuncishiswe ukulahleka kwesisindo sezakhi ze-organic kuphethiloli, uphethiloli osetshenziswayo kufanele uhlangabezane nezidingo zokuklanywa kwamabhayela nezinye izinto zokusebenza ezivuthayo ukuze kuncishiswe ukumosheka kwamandla enqubweni yokuvutha.
(2) Ubuchwepheshe bokunciphisa ukukhishwa kwekhabhoni
Inqubo ingase ibangele ukukhishwa okuqondile kwamagesi abamba ukushisa njenge-CO2, noma ukusetshenziswa kabusha kwe-CO2. Izinyathelo zobuchwepheshe zingathathwa ukunciphisa ukukhishwa kwekhabhoni.
Enqubweni yokuqinisekisa ukukhishwa kwekhabhoni, inqubo yokukhishwa kwekhabhoni ayifaki ukukhishwa kwekhabhoni okuvela ekushisweni kukaphethiloli kanye nogesi othengiwe nokushisa. Nokho, inqubo idlala indima ebalulekile ekukhishweni kwekhabhoni yalo lonke ibhizinisi (noma umkhiqizo). Ngokuthuthukiswa kwenqubo, inani likaphethiloli othengiwe lingancishiswa kakhulu.
Amabhizinisi agxile ekukhiqizeni anganciphisa ukungcoliswa kwemvelo emphakathini ngokunciphisa ukukhishwa kwekhabhoni kaphethiloli kanye nobuchwepheshe bokunciphisa ukukhishwa kwekhabhoni. Ngokwethula okokusebenza kwe-Nobeth steam generator kanye nokuhlanganisa okuqukethwe kokukhiqizwa kwebhizinisi ngokwalo, bangakwazi ukunquma inani lesitimu abasidingayo njengesisekelo. Khetha amandla akalwe afaneleke kakhulu kanye nenani lamajeneretha esitimu segesi. Ngalesi sikhathi, ukulahlekelwa okubangelwa ngesikhathi sokusetshenziswa kwangempela kuzoncishiswa, futhi umphumela wokulondoloza amandla uzoba sobala kakhulu.
Isimiso sokusebenza se-steam generator ukuxhumana ngokugcwele nomoya ngophethiloli. Ngosizo lwe-oksijeni, uphethiloli uzoshisa ngokugcwele, okungagcini nje ukunciphisa ukukhishwa kwezinto ezingcolile, kodwa futhi kuthuthukisa izinga langempela lokusebenzisa uphethiloli. Uma kuqhathaniswa nama-boilers ajwayelekile, amajeneretha e-steam anganciphisa izinga lokushisa legesi yokukhipha i-boiler futhi athuthukise ukusebenza kahle kokushisa kwe-boiler. Ingase futhi ithuthukise ukusebenza kahle futhi yonge izindleko.
Ngakho-ke, ezindaweni ezinegesi, kubiza kakhulu ukusebenzisa ama-generator e-gas steam. Uma kuqhathaniswa nezinye izinhlobo ze-fuel steam generator, ama-fuel steam generator awakwazi nje ukulondoloza ukusetshenziswa kwamafutha, kodwa futhi anciphise ukungcola.
