'Dizzying' impinduka ziza mu nganda zo mu nyanja - ClassNK

Ikibazo gikubiyemo imbaraga mu kigo gishinzwe igenamigambi n’ibishushanyo mbonera by’amato meza (GSC), iterambere rya sisitemu yo gufata karubone mu bwato, hamwe n’icyizere cy’ubwato bw’amashanyarazi bwiswe RoboShip.

Kuri GSC, Ryutaro Kakiuchi yasobanuye mu buryo burambuye ibyagezweho mu rwego rwo kugenzura no guhanura ibiciro by'ibicanwa bito bito na zero-karubone kugeza mu 2050. Mu cyerekezo cya lisansi ya karubone y’amato agenda mu nyanja, Kakiuchi agaragaza amoniya y'ubururu nk'inyungu nziza cyane. lisansi ya karubone ukurikije ibiciro byafashwe, nubwo lisansi ifite imyuka ya N2O no gukemura ibibazo.

Ibiciro nibitangwa bikikije ibicanwa bitagira aho bibogamiye nka methanol na metani, kandi uburenganzira bwo kohereza imyuka ya CO2 yafashwe bivuye mu mwuka bikenera gusobanurwa mugihe itangwa ariryo mpungenge nyamukuru yibikomoka kuri biyogi, nubwo ubwoko bumwebumwe bwa moteri bushobora gukoresha ibicanwa nkibicanwa byindege.

GSC yifashishije imiterere iriho ubu, ikoranabuhanga n’ibikomoka kuri peteroli nkaho itazwi ndetse n’ishusho y’ejo hazaza “opaque,” ​​ariko, GSC yashyizeho urufatiro rw’ibishushanyo mbonera by’icyatsi kibisi, harimo n’ubuyapani bwa mbere bwatewe na amoniya bwatewe na amoniya bwatanzwe na AiP mu ntangiriro zuyu mwaka.

Raporo yagize ati: "Nubwo amoniya y'ubururu iteganijwe kuba ihendutse mu bicanwa bitandukanye bya zeru-karubone, hafatwa ko ibiciro bizakomeza kuba hejuru cyane ugereranije n'ibicanwa by'ubwato biriho ubu".

Yakomeje agira ati: “Duhereye ku kwemeza ko ingufu zigenda neza, hari n'ibitekerezo bikomeye byo gushyigikira ibicanwa (metani na methanol) kubera ko ibyo bicanwa bishobora gukoresha ibikorwa remezo bihari.Byongeye kandi, munzira ngufi, ingufu zose zisabwa ni nto, byerekana ko bishoboka gukoresha hydrogène cyangwa amashanyarazi (selile lisansi, bateri, nibindi).Biteganijwe ko ubwoko butandukanye bwa lisansi buzakoreshwa mu gihe kiri imbere, bitewe n'inzira n'ubwato. ”

Raporo kandi yihanangirije ko ishyirwaho ry’ingamba zikomeye za karubone zishobora kugabanya igihe cyateganijwe cy’amato mu gihe inzibacyuho ya karubone zero.Ikigo cyavuze ko iki kigo gikomeje kwiga ibisubizo byatanzwe mu rwego rwo kurushaho gusobanukirwa no kumenyesha abakiriya.

Ati: “Impinduka zigenda ziyongera ku isi igamije kugera ku myuka ya 2050 zeru, harimo n’ingamba zashyizweho, biteganijwe mu gihe kiri imbere, kandi kurushaho kumenyekanisha agaciro k’ibidukikije ka decarbonisation byongera igitutu cyo gushyiraho ibipimo ngenderwaho binyuranye n’ubukungu.Birashoboka kandi ko ishyirwaho rya sisitemu yo kugenzura CII bizagira ingaruka zikomeye zigabanya ubuzima bwibicuruzwa byubwato, nubwo ubuzima burebure bwimyaka irenga 20 nyuma yubwubatsi bwafashwe nkukuri kugeza ubu.Ukurikije ubu bwoko bwisi yose, abakoresha bakoresha kandi bayobora amato bagomba noneho gufata ibyemezo bitoroshye kuruta mubihe byashize bijyanye ningaruka zubucuruzi zijyanye no kwamburwa amato, nubwoko bwubwato bagomba kugura mugihe cyinzibacyuho kuri zeru karubone. ”

Hanze y’ibyuka bihumanya ikirere, ibibazo binasuzuma isesengura ry’amazi azaza, impinduka no kuvugurura amategeko yerekeye ubushakashatsi ku bwato n’ubwubatsi, inyongeramusaruro, hamwe n’insanganyamatsiko za IMO ziherutse.
