Haufinyane tjena, Hydro ea Norway e ile ea lokolla tlaleho e ipolelang hore e fihletse ho se nke lehlakore ha k'hamphani ka bophara ka 2019, le hore e kene nakong ea khabone ho tloha 2020. Ke khoasolla tlaleho ho tsoa webosaeteng ea semmuso ea k'hamphani mme ka shebisisa hore na Hydro e fihletse ho se nke lehlakore ha carbon joang. ha lik'hamphani tse ngata li ne li ntse li le sethaleng sa "carbon peak".
Ha re boneng sephetho pele.
Ka 2013, Hydro e ile ea qala leano la boemo ba leholimo ka sepheo sa ho se nke lehlakore ka carbon ho tloha ponong ea potoloho ea bophelo ka 2020. Ka kopo hlokomela hore, ho latela pono ea potoloho ea bophelo.
A re hlahlobeng chate e latelang.Ho tloha ka 2014, tlhahiso ea khabone ea k'hamphani eohle e ntse e fokotseha selemo le selemo, 'me e fokotsehile ho ea ka tlase ho zero ka 2019, ke hore, tlhahiso ea khabone ea k'hamphani eohle ts'ebetsong ea tlhahiso le ts'ebetso e tlase ho feta phokotso ea tlhahiso. ya sehlahiswa boemong ba tshebediso.
Liphetho tsa likarabello li bonts'a hore ka selemo sa 2019, tlhahiso ea khabone e tobileng ea Hydro e ne e le lithane tse limilione tse 8.434, khabone e sa tobang e ne e le lithane tse limilione tse 4.969, mme tlhahiso e bakoang ke ho senngoa ha meru e ne e le lithane tse 35,000, ka kakaretso ea lithane tse limilione tse 13.438.Litefiso tsa khabone tseo lihlahisoa tsa Hydro li ka li fumanang sethaleng sa ts'ebeliso li lekana le lithane tse limilione tse 13.657, 'me ka mor'a hore ho ntšoa ha khabone le likalimo tsa khabone li felisoe, tlhahiso ea carbon ea Hydro ke lithane tse 219,000 tse mpe.
Jwale seo se sebetsa jwang.
Ea pele, tlhaloso.Ho latela pono ea potoloho ea bophelo, ho se nke lehlakore ha carbon ho ka hlalosoa ka litsela tse ngata.Ho leano la boemo ba leholimo la Hydro, ho se nke lehlakore ha khabone ho hlalosoa e le tekano lipakeng tsa mesi nakong ea ts'ebetso ea tlhahiso le phokotso ea mesi nakong ea ts'ebeliso ea sehlahisoa.
Moetso ona oa lipalo oa potoloho ea bophelo o bohlokoa.
Mefuta ea boemo ba leholimo ea Hydro, ho ea ka pono ea k'hamphani, e akaretsa likhoebo tsohle tse tlas'a beng ba k'hamphani, Palo ea khabone ea mohlala e akaretsa sebaka sa 1 (tsohle tse hlahisoang ka kotloloho ke likhase tse futhumatsang lefatše) le likhase tsa Scope 2 (likhase tse sa tobang ka lebaka la motlakase o rekiloeng, mocheso kapa mocheso. mouoane) joalo ka ha ho hlalositsoe ke Lekhotla la Lefatše la Khoebo bakeng sa Ntlafatso ea Moshoelella WBCSD GHG Protocol.
Hydro e hlahisitse lithane tse limilione tse 2.04 tsa aluminium ea mantlha ka selemo sa 2019, mme haeba tlhahiso ea khabone e le lithane tse 16.51 tsa CO²/ ton ea aluminium ho latela karolelano ea lefatše, joale tlhahiso ea khabone ka selemo sa 2019 e lokela ho ba lithane tse limilione tse 33.68, empa sephetho ke limilione tse 13.403 feela. lithane (843.4+496.9), tse ka tlaase ho tekanyo ea lefatše ea khabone.
Habohlokoa le ho feta, mohlala o boetse o balile phokotso ea tlhahiso e tlisoang ke lihlahisoa tsa aluminium sethaleng sa tšebeliso, ke hore, palo ea lithane tse limilione tse -13.657 setšoantšong se ka holimo.
Hydro haholo-holo e fokotsa boemo ba khabone ho pholletsa le khamphani ka litsela tse latelang.

[2] Eketsa tšebeliso ea aluminium e sebelisoang hape
[3] Bala phokotso ea khabone ea lihlahisoa tsa Hydro nakong ea ts'ebeliso
Ka hona, halofo ea ho se nke lehlakore ha carbon ea Hydro e finyelloa ka ho fokotsa tlhahiso ea theknoloji, 'me halofo e' ngoe e baloa ka mehlala.
1.Matla a Metsi
Hydro ke k'hamphani ea boraro e kholo ka ho fetisisa ea ho fehla matla a metsi Norway, e nang le matla a tloaelehileng a selemo le selemo a 10TWh, e sebelisetsoang tlhahiso ea aluminium ea electrolytic.Khabone e hlahisoang ke aluminiamo e tsoang mohlatleng oa metsi e tlase ho feta karolelano ea lefatše, hobane boholo ba tlhahiso ea aluminium ea mantlha ea lefats'e e sebelisa motlakase o fehloang ho tsoa linthong tsa khale tse kang khase ea tlhaho kapa mashala.Moetsong ona, tlhahiso ea aluminium ea Hydro e tla tlosa aluminium e 'ngoe 'marakeng oa lefatše, e lekanang le ho fokotsa likhase.(Manahano ana a kopane.) Karolo ena e ipapisitse le phapang lipakeng tsa aluminium e hlahisoang ke motlakase o fehloang ka metsi le karolelano ea lefatše lohle, e hlahisoang ke kakaretso ea likhase tsa Hydro ka mokhoa o latelang:
Moo: 14.9 ke karolelano ea lefatše ea tšebeliso ea motlakase bakeng sa tlhahiso ea aluminium ea 14.9 kWh / kg, 'me 5.2 ke phapang pakeng tsa tlhahiso ea carbon ea aluminium e hlahisoang ke Hydro le "karolelano ea lefatše" (ntle le Chaena).Lipalo ka bobeli li thehiloe tlalehong ea Mokhatlo oa Machaba oa Aluminium.
2. Ho sebelisoa aluminium e ngata e sebelisoang hape
Aluminium ke tšepe e ka sebelisoang hape ka nako e sa lekanyetsoang.Mesi ea khabone ea aluminium e sebelisoang hape e ka ba 5% feela ea ea aluminium ea mantlha, 'me Hydro e fokotsa tlhahiso ea eona ea khabone ka kakaretso ka tšebeliso e pharaletseng ea aluminium e sebelisoang hape.
Ka matla a fehloang ka metsi le ho eketsoa ha aluminium e sebelisoang hape, Hydro e khonne ho fokotsa khabone ea lihlahisoa tsa aluminium ho ea ka tlase ho lithane tse 4 tsa CO²/ton ea aluminium, esita le ho fihla ka tlase ho lithane tse 2 tsa CO²/ton ea aluminium.Lihlahisoa tsa alloy tsa Hydro's CIRCAL 75R li sebelisa ho feta 75% ea aluminium e sebelisoang hape.
3. Bala phokotso ea khabone e hlahisoang ke sethala sa tšebeliso ea lihlahisoa tsa aluminium
Mohlala oa Hydro o lumela hore le hoja aluminium ea mantlha e tla hlahisa likhase tse ngata tsa sethopo sethaleng sa tlhahiso, tšebeliso e bobebe ea aluminium e ka fokotsa haholo tšebeliso ea matla, kahoo e fokotsa ho tsoa ha khase e futhumatsang mocheso sethaleng sa tšebeliso, le karolo ena ea phokotso ea mocheso e bakoang ke Tšebeliso e bobebe ea aluminium e boetse e baloa molemong oa monehelo o sa nke lehlakore oa carbon oa Hydro, ke hore, palo ea lithane tse limilione tse 13.657.(Monahano ona o batla o rarahane ebile o thata ho o latela.)
Hobane Hydro e rekisa lihlahisoa tsa aluminium feela, e hlokomela ts'ebeliso ea terminal ea aluminium ka likhoebo tse ling tsa ketane ea indasteri.Mona, Hydro e sebelisa Life-Cycle Assessment (LCA), e ipolelang hore ke motho oa boraro ea ikemetseng.
Mohlala, lefapheng la lipalangoang, lithuto tsa mokha oa boraro li bonts'itse hore bakeng sa 1kg e 'ngoe le e' ngoe ea aluminium e nkeloang sebaka ke 2kg ea tšepe, 13-23kg ea CO² e ka fokotsoa nakong ea bophelo ba koloi.Ho ipapisitsoe le bongata ba lihlahisoa tsa aluminium tse rekisetsoang liindasteri tse fapaneng tse tlase, joalo ka ho paka, ho haha, sehatsetsi, joalo-joalo, Hydro e lekanya phokotso ea tlhahiso e bakoang ke lihlahisoa tsa aluminium tse hlahisoang ke Hydro.
