Liphetoho tsa 'Dizzying' ho tla indastering ea maritime - ClassNK

Taba ena e akaretsa matsapa Setsing sa Meralo le Boqapi bakeng sa Likepe tse Tala (GSC), nts'etsopele ea litsamaiso tsa ho ts'oaroa ha carbon, le menyetla ea sekepe sa motlakase se bitsoang RoboShip.

Bakeng sa GSC, Ryutaro Kakiuchi o hlalositse nts'etsopele ea morao-rao ea taolo ka botlalo le ho bolela esale pele litšenyehelo tsa mafura a fapaneng a tlase le a zero-carbon ho fihlela ka 2050. Ka tebello ea mafura a khabone a zero bakeng sa likepe tse tsamaeang leoatleng, Kakiuchi o totobatsa ammonia e putsoa e le eona e molemo ka ho fetisisa. mafura a khabone ea zero ho latela litšenyehelo tse nahanoang tsa tlhahiso, leha e le mafura a nang le tlhahiso ea N2O le ho sebetsana le mathata.

Lipotso tsa litheko le phepelo li pota-potile mafura a maiketsetso a sa nkeng khabone joalo ka methanol le methane, le litokelo tsa ho ntšoa ha CO2 e nkuoeng ho tsoa ho li hloka ho hlakisoa ha phepelo e le eona ntho e amehang haholo mabapi le lifuele tsa tlhaho, leha mefuta e meng ea enjine e ka sebelisa biofuel joalo ka mafura a sefofane.

Ha e bua ka boemo ba hajoale ba taolo, theknoloji le mafura e le ntho e sa tsitsang le setšoantšo sa "opaque" ea kamoso, GSC leha ho le joalo e ralile motheo bakeng sa meralo ea likepe tse tala tsa kamoso, ho kenyeletsoa panamax ea pele ea Japane e fehlang ammonia e ileng ea fuoa AiP pejana selemong sena.

"Le hoja ammonia e putsoa e boleloa esale pele hore e batla e le theko e tlaase har'a mefuta e fapaneng ea libeso tsa zero-carbon, ho nahanoa hore litheko li ntse li tla ba holimo haholo ho feta tsa libeso tsa likepe tsa hajoale," ho boletse tlaleho.

"Ho ea ka pono ea ho netefatsa hore ho na le phetoho e bonolo ea matla, ho boetse ho na le maikutlo a matla mabapi le mafura a maiketsetso (methane le methanol) hobane mafura ana a ka sebelisa lisebelisoa tse teng.Ho feta moo, litseleng tse khutšoanyane, matla a matla a hlokahalang a nyenyane, a fana ka maikutlo a monyetla oa ho sebelisa hydrogen kapa matla a motlakase (lisele tsa mafura, libeteri, joalo-joalo).Kahoo, ho lebelletsoe hore nakong e tlang ho tla sebelisoa libeso tsa mefuta e fapaneng, ho latela tsela le mofuta oa sekepe.”

Tlaleho e boetse e lemositse hore ho hlahisoa ha mehato ea matla a khabone ho ka khutsufatsa bophelo bo lebelletsoeng ba likepe ha phetoho ea khabone ea zero e ntse e tsoela pele.Setsi se ntse se tsoela pele ho ithuta litharollo tse reriloeng molemong oa ho tebisa kutloisiso ea sona le ho tsebisa bareki.

"Liphetoho tse makatsang litloaelong tsa lefats'e tse shebaneng le phihlello ea likhase tsa 2050, ho kenyeletsoa le metsamao ea taolo, li lebelletsoe nakong e tlang, mme tlhokomeliso e matla ea boleng ba tikoloho ea decarbonization e eketsa khatello ea ho amohela litekanyetso tsa tlhahlobo tse khahlanong le katleho ea moruo.Hape ho ka etsahala hore ho kenyelletsoa ha tsamaiso ea litekanyetso tsa CII ho tla ba le tšusumetso e tebileng e fokotsang bophelo ba lihlahisoa tsa likepe, le hoja bophelo bo bolelele ba ts'ebetso ea lilemo tse fetang 20 ka mor'a hore kaho e nkiloe habonolo ho fihlela joale.Ho ipapisitsoe le mefuta ena ea litloaelo tsa lefats'e, basebelisi ba sebetsang le ho tsamaisa likepe joale ba tlameha ho etsa liqeto tse boima ho feta nakong e fetileng mabapi le likotsi tsa khoebo tse amanang le ho senyeha ha likepe, le mefuta ea likepe tseo ba lokelang ho li reka nakong ea phetoho ho ea ho zero. carbon.”
