Kusintha kwa 'Dizzying' kuti abwere ku mafakitale apanyanja - ClassNK

Nkhaniyi ikukhudza zoyesayesa za Planning and Design Center for Greener Ships (GSC), kakulidwe ka makina onyamula mpweya wapanyanja, komanso chiyembekezo cha sitima yamagetsi yotchedwa RoboShip.

Kwa GSC, Ryutaro Kakiuchi adafotokoza mwatsatanetsatane zomwe zachitika posachedwa komanso kulosera zamitengo yamafuta otsika ndi zero-carbon kudzera mu 2050. Potengera mafuta a carbon omwe amapita kunyanja, Kakiuchi akuwonetsa kuti ammonia wa buluu ndi wopindulitsa kwambiri. Mafuta a zero-carbon potengera mtengo wopangira, ngakhale mafuta okhala ndi mpweya wa N2O komanso kuthana ndi nkhawa.

Mafunso okhudzana ndi mtengo ndi kagayidwe kawo amazungulira mafuta opangira kaboni osalowerera ndale monga methanol ndi methane, komanso ufulu wotulutsa mpweya wa CO2 wotengedwa kuchokera ku utsi wofunikira kufotokozedwa pomwe kupezeka kuli komwe kumadetsa nkhawa kwambiri pamafuta amafuta, ngakhale mitundu ina ya injini imatha kugwiritsa ntchito mafuta opangira mafuta monga mafuta oyendetsa.

"Ngakhale kuti ammonia a blue ammonia akuyembekezeredwa kukhala otsika mtengo pakati pa mafuta osiyanasiyana a zero-carbon, zikuganiziridwa kuti mitengo idzakhala yokwera kwambiri kuposa yamafuta amasiku ano," lipotilo linatero.

"Kutengera kuwonetsetsa kuti magetsi aziyenda bwino, palinso malingaliro amphamvu okomera mafuta opangira (methane ndi methanol) chifukwa mafutawa amatha kugwiritsa ntchito zida zomwe zilipo.Komanso, panjira zazitali, mphamvu zonse zomwe zimafunikira ndizochepa, zomwe zikuwonetsa kuthekera kogwiritsa ntchito hydrogen kapena mphamvu yamagetsi (ma cell amafuta, mabatire, ndi zina).Chifukwa chake, mitundu yosiyanasiyana yamafuta akuyembekezeka kugwiritsidwa ntchito mtsogolo, kutengera njira ndi mtundu wa sitimayo.

Lipotilo lidachenjezanso kuti kukhazikitsidwa kwa njira zamphamvu za kaboni kungafupikitse moyo wa zombo zomwe zikuyembekezeka pomwe kusintha kwa zero carbon kukuchitika.Center ikupitilizabe kuphunzira mayankho omwe aperekedwa pofuna kukulitsa kumvetsetsa kwawo ndikudziwitsa makasitomala, idatero.

"Kusintha kodabwitsa kwa zochitika zapadziko lapansi zomwe zikukhudzana ndi kukwaniritsidwa kwa mpweya wa 2050, kuphatikiza zowongolera, zikuyembekezeredwa mtsogolomo, ndipo kuzindikira kokulirapo za kufunika kwa chilengedwe cha decarbonization kumawonjezera kukakamizidwa kuti atsatire miyezo yowunikira yomwe ikusemphana ndi kayendetsedwe kazachuma.N'zothekanso kuti kukhazikitsidwa kwa ndondomeko ya CII kudzakhala ndi vuto lalikulu lomwe limachepetsa moyo wa katundu wa zombo, ngakhale kuti moyo wautali wogwira ntchito wa zaka zopitirira 20 pambuyo pomanga watengedwa mopepuka mpaka pano.Kutengera zamitundu iyi yapadziko lonse lapansi, ogwiritsa ntchito ndi kuyang'anira zombo ayenera tsopano kupanga zisankho zovuta kwambiri kuposa m'mbuyomu zokhudzana ndi kuwopsa kwa bizinesi komwe kumakhudzana ndi kuwononga zombo zapamadzi, komanso mitundu ya zombo zomwe ayenera kugula panthawi yosinthira kupita ku ziro. carbon.”

Kunja kwa zomwe zimayang'ana pakutulutsa, nkhanizi zimawunikiranso kusanthula kwamtsogolo kwa fluidics, kusintha ndi kusinthidwa kwa malamulo okhudza kafukufuku wa zombo ndi zomangamanga, zowonjezera za dzimbiri, ndi mitu yaposachedwa ya IMO.
