Kugwiritsiridwa ntchito kwa methanol wobiriwira, mafuta osalowerera ndale omwe amapezeka kuchokera kuzinthu zongowonjezwdwanso (zotsalira zazomera ndi mphamvu yadzuwa, mwachitsanzo), zidzalola ma mega-containers asanu ndi atatu a Maersk (AP Moller-Maersk) kutulutsa pafupifupi matani miliyoni imodzi kuchepera kuposa CO2 pa chaka. Mu 2020, Maersk adatulutsa matani 33 miliyoni a CO2.
Zombo zatsopano, zomwe zikumangidwa ku South Korea, ndi Hyundai Heavy Industries - Hyundai samangopanga magalimoto -, ngati zonse zikuyenda monga momwe anakonzera, zidzaperekedwa kumayambiriro kwa 2024 ndipo zidzakhala ndi mphamvu zokwana pafupifupi 16 zikwi zikwi ( TEU) aliyense.
Zombo zisanu ndi zitatu zatsopanozi ndi gawo la mapulani okonzanso zombo za Maersk ndi mapulani ake oti akwaniritse kusalowerera ndale mu 2050 kwa onyamula panyanja wamkulu kwambiri padziko lonse lapansi, ndi mgwirizano womwe udasainidwa ndi Hyundai Heavy Industries kukhalabe ndi mwayi woti zombo zina zinayi zimangidwe pofika 2025. .
Kuphatikiza pa cholinga chake chamkati chokhala osalowerera ndale pofika 2050, Maersk ikuyankhanso zomwe makasitomala ake akufuna. Opitilira theka lamakasitomala 200 apamwamba a Maersk, komwe timapeza mayina ngati Amazon, Disney kapena Microsoft, akuyikanso zolinga zochepetsera utsi pamaketani awo ogulitsa.
Vuto lalikulu si injini.
Ma injini a dizilo omwe adzakonzekeretse zombozi atha kuthamanga osati pa methanol wobiriwira, komanso pamafuta olemera, mafuta achikhalidwe m'sitima zapamadzi izi, ngakhale kuti ali ndi sulfure wocheperako (kuwongolera mpweya woyipa wa sulfure). oxides kapena SOx).Kukhala ndi mwayi wogwira ntchito ndi mafuta awiri osiyana kunali kofunika kuti zombo zigwire ntchito, mosasamala kanthu za dera la dziko lapansi kumene zimagwira ntchito kapena kupezeka kwa methanol wobiriwira, womwe udakali wosowa pamsika - kupezeka kwa mafuta ongowonjezwdwa komanso opangira. imakhudzanso galimoto yamakampani.
Ili ndiye vuto lalikulu, akutero Maersk: kupeza, kuyambira tsiku loyamba, kuperekedwa kwa kuchuluka koyenera kwa methanol wobiriwira kuti apereke zombo zake, popeza ngakhale ndi "zokha" zisanu ndi zitatu (zazikuluzikulu) zombo, zidzakakamiza kwambiri kuwonjezera kupanga mafuta osagwirizana ndi carbon awa. Pachifukwa ichi, Maersk yakhazikitsa ndikuyang'ana kukhazikitsa mgwirizano ndi mgwirizano ndi ochita masewerawa.
Kuthekera kwa injini izi kuyendetsa pamafuta awiri osiyanasiyana kudzapangitsa mtengo wa chotengera chilichonse kukhala 10% mpaka 15% kuposa masiku onse, kuyimirira pafupifupi 148 miliyoni mayuro chilichonse.
Akadali pa methanol wobiriwira, akhoza kukhala chiyambi (e-methanol) kapena akhoza kupangidwa zisathe (bio-methanol), mwachindunji kuchokera zotsalira zazomera kapena pogwiritsa ntchito zongowonjezwdwa wa hydrogen, pamodzi ndi mpweya woipa kuchokera biomass kapena kugwidwa mpweya woipa.
Nkhani yabwino kwamakampani opanga magalimoto?
Osakayikira. Kulowa kwa "zimphona zazikulu za m'nyanja" mumafuta opangira kapena ongowonjezera kudzakhala kofunika kwambiri kuti pakhale njira yofunikira kwambiri yopangira mafuta oyaka, yomwe ingakhale ndi zotsatira zabwino pakuchepetsa kutulutsa mpweya wowonjezera kutentha.
Ma injini oyatsira mkati akhoza kukhala "otayika" pakapita nthawi, koma izi sizikutanthauza kuti sangathe kuthandizira kuchepetsa mpweya.
