Nguva pfupi yadarika, Hydro yekuNorway yakaburitsa chirevo ichiti yakawana kusarerekera kwekabhoni kwese kwese kwekambani muna 2019, uye kupinda munguva yekabhoni kubva muna 2020. Ndakatora mushumo kubva pawebhusaiti yekambani yepamutemo ndikanyatsotarisa kuti Hydro yakawana sei kusarerekera kabhoni. apo makambani mazhinji akange achiri mu "carbon peak" nhanho.
Ngatione mhedzisiro kutanga.
Muna 2013, Hydro yakatanga chirongwa chemamiriro ekunze nechinangwa chekuve kabhoni isina kwayakarerekera kubva pakuona kwehupenyu-kutenderera panosvika 2020. Ndokumbira uzive kuti, kubva pakuona kwehupenyu.
Ngatitarisei chati inotevera. Kubva 2014, carbon emission yekambani yese yanga ichidzikira gore negore, uye yakaderedzwa kusvika pazasi zero muna 2019, kureva kuti, kuburitsa kabhoni kwekambani yese mukugadzira nekuita basa kwakadzikira pane kudzikisira. yechigadzirwa muchikamu chekushandisa.
Mhedzisiro yeaccounting inoratidza kuti muna 2019, Hydro's yakananga kabhoni emissions yaive 8.434 miriyoni matani, isina kunanga kabhoni emission yaive 4.969 miriyoni matani, uye kubuda kwakakonzerwa nekutemwa kwemasango kwaive 35,000 matani, nekubuda kwematani 13.438 miriyoni. Iyo kabhoni makiredhiti ayo zvigadzirwa zveHydro zvinogona kuwana muchikamu chekushandisa akaenzana ne13.657 miriyoni matani, uye mushure meiyo kabhoni emissions uye kabhoni kiredhiti yadzikiswa, Hydro's kabhoni emissions yakaipa 219,000 matani.
Zvino zvinoshanda sei.
Kutanga, tsananguro. Kubva pamaonero ehupenyu, kusarerekera kabhoni kunogona kutsanangurwa nenzira dzakati wandei. MuHydro's mamiriro ekunze emamiriro ekunze, kusarerekera kabhoni kunotsanangurwa sechiyero pakati pezvinobuda panguva yekugadzira uye kudzikiswa kwehutsi panguva yekushandiswa kwechigadzirwa.
Iyi modhi yekuverenga yehupenyu yakakosha.
Mamiriro ekunze eHydro, kubva pakuona kwekambani, anovhara mabhizinesi ese ari pasi pemuridzi wekambani, Iyo modhi kabhoni emission kuverenga inovhara ese chiyero 1 (ese akananga greenhouse gasi emissions) uye Scope 2 emissions (isina kunanga greenhouse gasi kuburitswa nekuda kwemagetsi akatengwa, kupisa kana mupfu) sekutsanangurwa kwazvinoitwa neWorld Business Council for Sustainable Development WBCSD GHG Protocol.
Hydro yakagadzira 2.04 miriyoni matani eprimary aluminium muna 2019, uye kana kabhoni yakabuda iri 16.51 matani eCO²/ toni yealuminium zvichienderana neavhareji yepasirese, ipapo kubuda kwekabhoni muna 2019 kunofanira kunge kuri matani 33.68 miriyoni, asi mhedzisiro ingori 13.403 miriyoni. matani (843.4+496.9), kure pasi penyika ye carbon emissions.
Zvinotonyanya kukosha, iyo modhi yakaverengerawo kuderedzwa kwekubuda kwakaunzwa nearuminiyamu zvigadzirwa muchikamu chekushandisa, ndiko kuti, nhamba ye -13.657 miriyoni matani mumufananidzo uri pamusoro.
Hydro inonyanya kuderedza huwandu hwekabhoni emissions mukambani yese kuburikidza nenzira dzinotevera.
[1] Kushandiswa kwesimba rinodzokororwa, uku uchivandudza tekinoroji yekudzikisa electrolytic aluminium kushandiswa kwemagetsi
[2] Wedzera kushandiswa kwearuminiyamu yakadzokororwa
[3] Verenga kuderedzwa kwekabhoni yezvigadzirwa zveHydro panguva yekushandisa
Naizvozvo, hafu yeHydro's kabhoni kusarerekera kunowanikwa kuburikidza nekudzikisa tekinoroji emission, uye imwe hafu inoverengerwa kuburikidza nemhando.
1.Mvura Simba
Hydro ikambani yechitatu yakakura kwazvo yehydropower muNorway, ine huwandu hwegore negore hwe10TWh, iyo inoshandiswa kugadzira electrolytic aluminum. Iyo kabhoni inobuda mukugadzira aruminiyamu kubva kusimba remvura yakadzikira pane avhareji yepasirese, nekuti mazhinji ekutanga kugadzirwa kwealuminium pasi rose anoshandisa magetsi anogadzirwa kubva mumafuta ezvicherwa zvakaita segasi rechisikigo kana marasha. Mune modhi, Hydro's hydropower kugadzirwa kwealuminium inobvisa imwe aruminiyamu mumusika wepasi rose, izvo zvakaenzana nekudzikisa kuburitswa. (Mafungiro aya akavhiringika.) Izvi zvinoenderana nemusiyano uripo pakati pearuminiyamu inogadzirwa kubva kusimba remvura neavhareji yepasi rose, inopihwa kuburitsa kweHydro kuzere neiyi fomula inotevera:
Ikoko: 14.9 ndiyo chiyero chepasi rose chekushandiswa kwemagetsi ekugadzirwa kwealuminium 14.9 kWh / kg aluminium, uye 5.2 ndiyo mutsauko pakati pe carbon emissions yealuminium inogadzirwa neHydro uye "avhareji yenyika" (kunze kweChina) level. Nhamba mbiri idzi dzakabva pamushumo weInternational Aluminium Association.
2. Aruminiyamu yakawanda inoshandiswa zvakare inoshandiswa
Aluminium isimbi inogona kushandiswazve kusinga peri. Iyo kabhoni inoburitsa aruminiyamu yakadzokororwa inongoita 5% yealuminium yekutanga, uye Hydro inoderedza kuburitswa kwayo kwekabhoni kuburikidza nekushandiswa kwakanyanya kwealuminum yakadzokororwa.
Kuburikidza nemagetsi emvura uye nekuwedzera kwealuminum yakadzokororwa, Hydro yakakwanisa kuderedza kuburitswa kwekabhoni yezvigadzirwa zvealuminium kusvika pasi pematani mana eCO²/tani yealuminium, uye kunyange kusvika pazasi pematani maviri eCO²/tani yealuminium. Hydro's CIRCAL 75R alloy zvigadzirwa zvinoshandisa zvinopfuura makumi manomwe neshanu muzana aruminiyamu yakadzokororwa.
3. Verenga kuderedzwa kwekabhoni emission inogadzirwa nedanho rekushandisa rezvigadzirwa zvealuminium
Hydro's modhi inotenda kuti kunyangwe yekutanga aluminium ichaburitsa akawanda egreenhouse magasi muchikamu chekugadzira, iyo lightweight application yealuminium inogona kuderedza zvakanyanya kushandiswa kwesimba, nekudaro ichidzikisa kuburitswa kwegreenhouse gasi muchikamu chekushandisa, uye ichi chikamu chekudzikisa kuburitswa kunokonzerwa ne kusareruka kwealuminium kushandiswa kwakaverengerwa mune kabhoni kusarerekera mupiro weHydro, kureva, nhamba ye13.657 miriyoni matani. (Iyi pfungwa yakaoma uye yakaoma kutevera.)
Nekuti Hydro inongotengesa zvigadzirwa zvealuminium, inoona iyo terminal application yealuminium kuburikidza nemamwe mabhizinesi ari mumaindasitiri ketani. Pano, Hydro inoshandisa Hupenyu-Cycle Assessment (LCA), iyo inoti ibato rakazvimirira rechitatu.
Semuyenzaniso, muchikamu chezvekufambisa, zvidzidzo zvebato rechitatu zvakaratidza kuti pa1kg yega yealuminium inotsiviwa ne2kg yesimbi, 13-23kg yeCO² inogona kudzikiswa pamusoro pehupenyu hwemotokari. Zvichienderana nehuwandu hwezvigadzirwa zvealuminium zvinotengeswa kune akasiyana maindasitiri epasi, akadai sekurongedza, kuvaka, firiji, nezvimwe, Hydro inoverengera kudzikiswa kwekubuda kunobva kune zvigadzirwa zvealuminium zvinogadzirwa neHydro.
