Posachedwapa, Hydro ya ku Norway idatulutsa lipoti loti idakwaniritsa kusalowerera ndale kwamakampani padziko lonse lapansi mu 2019, komanso kuti idalowa munyengo ya carbon negative kuyambira 2020. Ndidatsitsa lipotilo patsamba lovomerezeka la kampaniyo ndikuwunika momwe Hydro idakwaniritsira kusalowerera ndale kwa carbon. pamene makampani ambiri anali akadali mu "carbon peak" siteji.
Tiyeni tiwone chotsatira choyamba.
Mu 2013, Hydro inayambitsa ndondomeko ya nyengo ndi cholinga chofuna kusalowerera ndale kuchokera ku moyo wa 2020. Chonde dziwani kuti, kuchokera ku moyo wozungulira.
Tiyeni tione tchati chotsatirachi. Kuyambira 2014, mpweya wa kampani yonse wakhala ukuchepa chaka ndi chaka, ndipo wachepetsedwa mpaka ziro mu 2019, ndiye kuti, mpweya wa kampani yonse pakupanga ndi kugwira ntchito ndi wotsika kuposa kuchepetsa mpweya. za mankhwala omwe akugwiritsidwa ntchito.
Zotsatira zowerengera zikuwonetsa kuti mu 2019, mpweya wa Hydro mwachindunji unali matani 8.434 miliyoni, mpweya wosalunjika unali matani 4.969 miliyoni, ndipo mpweya womwe udabwera chifukwa chakudula mitengo unali matani 35,000, ndipo umatulutsa matani 13.438 miliyoni. Zopatsa kaboni zomwe zopangidwa ndi Hydro zitha kupezeka pakugwiritsa ntchito ndizofanana ndi matani 13.657 miliyoni, ndipo mpweya wotulutsa kaboni ndi carbon credits utatha, mpweya wa Hydro umakhala woipa matani 219,000.
Tsopano izo zimagwira ntchito bwanji.
Choyamba, tanthauzo. Kuchokera pamalingaliro a moyo, kusalowerera ndale kwa carbon kungatanthauzidwe m'njira zingapo. Mundondomeko yanyengo ya Hydro, kusalowerera ndale kwa kaboni kumatanthauzidwa ngati kusanja komwe kulipo pakati pa mpweya womwe umapangidwa panthawi yopanga ndikuchepetsa kutulutsa kwamafuta panthawi yogwiritsira ntchito.
Njira yowerengera moyo wanu ndiyofunikira.
Mitundu yanyengo ya Hydro, malinga ndi momwe kampani ikuyendera, imakhudza mabizinesi onse omwe ali ndi umwini wamakampani, Kuwerengera kwa mpweya wa kaboni kumakhudza mbali zonse 1 (zonse zotulutsa mpweya wowonjezera kutentha) ndi mpweya wa Scope 2 (kutulutsa kwa gasi wosalunjika chifukwa cha magetsi ogulidwa, kutentha kapena kutentha). steam) monga tafotokozera ndi World Business Council for Sustainable Development WBCSD GHG Protocol.
Hydro idatulutsa matani 2.04 miliyoni a aluminiyamu yoyamba mu 2019, ndipo ngati mpweya wotulutsa mpweya ndi matani 16.51 a CO²/ tani ya aluminiyamu malinga ndi avareji yapadziko lonse lapansi, ndiye kuti mpweya wa kaboni mu 2019 uyenera kukhala matani 33.68 miliyoni, koma zotsatira zake ndi 13.403 miliyoni zokha. matani (843.4+496.9), pansi kwambiri pamlingo wapadziko lonse wa mpweya wa carbon.
Chofunika kwambiri, chitsanzocho chinawerengeranso kuchepetsa mpweya umene umabweretsedwa ndi zinthu za aluminiyamu zomwe zimagwiritsidwa ntchito, ndiye kuti, chiwerengero cha -13.657 miliyoni matani pachithunzi pamwambapa.
Hydro makamaka amachepetsa kuchuluka kwa mpweya wotulutsa kaboni kukampani yonse kudzera m'njira zotsatirazi.
[1] Kugwiritsa ntchito mphamvu zongowonjezwdwa, ndikuwongolera ukadaulo wochepetsera kugwiritsa ntchito magetsi a electrolytic aluminium
[2] Wonjezerani kugwiritsa ntchito aluminiyumu yobwezeretsanso
[3] Werengetsani kuchepa kwa kaboni kwa zinthu za Hydro panthawi yogwiritsira ntchito
Chifukwa chake, theka la kusalowerera ndale kwa kaboni wa Hydro kumatheka kudzera muukadaulo wochepetsera mpweya, ndipo theka lina limawerengedwa kudzera mumitundu.
1.Mphamvu ya Madzi
Hydro ndi kampani yachitatu yayikulu kwambiri yopangira magetsi ku Norway, yomwe ili ndi mphamvu yapachaka ya 10TWh, yomwe imagwiritsidwa ntchito popanga aluminiyamu ya electrolytic. Mpweya wotulutsa kaboni wopangidwa ndi aluminiyamu kuchokera kumagetsi opangira madzi ndi wotsika poyerekeza ndi wapakati padziko lonse lapansi, chifukwa zida zambiri zopangira aluminiyamu padziko lonse lapansi zimagwiritsa ntchito magetsi opangidwa kuchokera kumafuta achilengedwe monga gasi kapena malasha. Muchitsanzochi, kupanga aluminiyamu ya Hydro hydropower kudzachotsa aluminiyumu ina pamsika wapadziko lonse lapansi, zomwe ndizofanana ndi kuchepetsa kutulutsa mpweya. (Nzeru iyi ndi yosokoneza.) Izi zinatengera kusiyana pakati pa aluminiyamu yopangidwa kuchokera ku mphamvu ya madzi ndi avareji yapadziko lonse lapansi, zomwe zimatengera kuchuluka kwa mpweya wa Hydro ndi njira iyi:
Kumene: 14.9 ndi padziko lonse lapansi mphamvu ya magetsi kwa zotayidwa kupanga 14.9 kWh/kg zotayidwa, ndi 5.2 ndi kusiyana mpweya mpweya wa aluminiyamu opangidwa ndi Hydro ndi "avereji padziko lonse" (kupatula China) mlingo. Ziwerengero zonsezi zimachokera ku lipoti la International Aluminium Association.
2. Aluminiyamu ambiri obwezerezedwanso amagwiritsidwa ntchito
Aluminiyamu ndi chitsulo chomwe chingathe kubwezeretsedwanso pafupifupi kwamuyaya. Mpweya wa kaboni wa aluminiyamu wokonzedwanso ndi pafupifupi 5% yokha ya aluminiyamu yoyamba, ndipo Hydro imachepetsa mpweya wake wonse wa kaboni pogwiritsa ntchito kwambiri aluminiyamu yobwezeretsanso.
Kupyolera mu mphamvu ya madzi ndi kuwonjezera kwa aluminiyamu yokonzedwanso, Hydro yatha kuchepetsa mpweya wa carbon wa zinthu za aluminiyamu kufika pansi pa matani 4 a CO²/tani ya aluminiyamu, ngakhalenso kufika pansi pa matani awiri a CO²/tani ya aluminiyamu. Zopangidwa ndi Hydro's CIRCAL 75R alloy zimagwiritsa ntchito aluminiyamu yopitilira 75%.
3. Kuwerengera kuchepetsa mpweya wa carbon wopangidwa ndi siteji yogwiritsira ntchito zinthu za aluminiyamu
Chitsanzo cha Hydro chimakhulupirira kuti ngakhale aluminiyamu yoyamba idzatulutsa mpweya wambiri wowonjezera kutentha panthawi yopangira, kugwiritsa ntchito zitsulo zopepuka za aluminiyamu kungachepetse kwambiri kugwiritsa ntchito mphamvu, potero kuchepetsa mpweya woipa wowonjezera kutentha panthawi yogwiritsira ntchito, ndi gawo ili la kuchepetsa mpweya chifukwa cha Kugwiritsidwa ntchito mopepuka kwa aluminiyamu kumawerengedwanso mu gawo lopanda kaboni la Hydro, ndiye kuti, matani 13.657 miliyoni. (Maganizo awa ndi ovuta komanso ovuta kuwatsatira.)
Chifukwa Hydro imangogulitsa zinthu za aluminiyamu, imazindikira kugwiritsa ntchito kwa aluminiyamu kudzera m'mabizinesi ena am'makampani. Apa, Hydro amagwiritsa ntchito Life-Cycle Assessment (LCA), yomwe imati ndi gulu lachitatu lodziyimira pawokha.
Mwachitsanzo, m'gawo lazamayendedwe, kafukufuku wa gulu lachitatu awonetsa kuti pa 1kg iliyonse ya aluminiyamu m'malo mwa 2kg yachitsulo, 13-23kg ya CO² imatha kuchepetsedwa pakadutsa moyo wagalimoto. Kutengera kuchuluka kwa zinthu za aluminiyamu zomwe zimagulitsidwa kumafakitale osiyanasiyana akumunsi, monga kulongedza, zomangamanga, firiji, ndi zina zambiri, Hydro amawerengera kuchepetsa utsi chifukwa cha zinthu za aluminiyamu zopangidwa ndi Hydro.
