'Dizzying' hloov mus rau kev lag luam maritime - ClassNK

Qhov teeb meem no suav nrog kev siv zog ntawm Planning and Design Center for Greener Ships (GSC), kev txhim kho ntawm onboard carbon capture systems, thiab lub zeem muag rau lub nkoj hluav taws xob dubbed RoboShip.

Rau GSC, Ryutaro Kakiuchi tau piav qhia txog cov kev cai tshiab tshaj plaws hauv kev nthuav dav thiab kwv yees cov nqi ntawm ntau yam qis- thiab xoom-carbon fuels txog xyoo 2050. Nyob rau hauv qhov kev xav rau xoom-carbon fuels rau dej hiav txwv-mus nkoj, Kakiuchi qhia txog xiav ammonia raws li qhov zoo tshaj plaws. xoom-carbon roj nyob rau hauv cov nqe lus ntawm assumed nqi ntau lawm, txawm tias ib tug roj nrog N2O emission thiab tuav kev txhawj xeeb.

Tus nqi thiab muab cov lus nug nyob ib puag ncig carbon-neutral hluavtaws roj xws li methanol thiab methane, thiab emissions txoj cai rau CO2 ntes los ntawm cov pa xav tau kev qhia meej thaum muab khoom yog qhov kev txhawj xeeb tseem ceeb nyob ib puag ncig biofuels, txawm hais tias qee hom cav yuav siv biofuels los ua roj.

Hais txog kev tswj hwm tam sim no, thev naus laus zis thiab roj toj roob hauv pes raws li qhov tsis paub tseeb thiab cov duab ntawm lub neej yav tom ntej "opaque," GSC tseem tau tso lub hauv paus rau kev tsim cov nkoj ntsuab yav tom ntej, suav nrog Nyiv thawj thawj ammonia-fueled panamax uas tau tso cai AiP ua ntej xyoo no.

"Txawm hais tias xiav ammonia tau kwv yees yuav pheej yig ntawm ntau yam xoom-carbon fuels, nws xav tias tus nqi tseem yuav siab dua li ntawm cov nkoj tam sim no," said tsab ntawv ceeb toom.

"Los ntawm qhov kev xav ntawm kev ua kom lub zog hloov pauv tau zoo, kuj tseem muaj kev xav zoo rau cov khoom siv hluav taws xob (methane thiab methanol) vim tias cov roj no tuaj yeem siv cov txheej txheem uas twb muaj lawm.Tsis tas li ntawd, nyob rau hauv txoj kev luv luv, tag nrho lub zog xav tau yog me me, qhia tias muaj peev xwm siv hydrogen lossis hluav taws xob hluav taws xob (roj hlwb, roj teeb, thiab lwm yam).Yog li, ntau hom roj yuav tsum tau siv yav tom ntej, nyob ntawm txoj kev thiab hom nkoj. "

Daim ntawv tshaj tawm kuj tau ceeb toom tias kev qhia txog kev siv cov pa roj carbon monoxide tuaj yeem ua rau luv luv lub neej ntawm cov hlab ntsha vim tias xoom carbon hloov pauv.Lub chaw tseem tab tom kawm ntxiv cov kev daws teeb meem hauv kev sib tw kom nkag siab nws tus kheej thiab qhia rau cov neeg siv khoom, nws hais.

"Dizzying hloov nyob rau hauv lub ntiaj teb no tiam sis lub hom phiaj ntawm kev ua tau zoo ntawm 2050 xoom emissions, nrog rau kev tswj kev txav, yuav tsum tau nyob rau hauv lub neej yav tom ntej, thiab siab paub txog tus nqi ntawm ib puag ncig ntawm decarbonization yuav ua rau kom lub siab los txais yuav cov qauv kev ntsuam xyuas uas tsis zoo rau economic efficiency.Nws tseem muaj peev xwm hais tias qhov kev taw qhia ntawm CII qhov ntsuas qhov system yuav muaj qhov cuam tshuam loj heev uas txwv cov khoom lag luam lub neej ntawm cov nkoj, txawm tias lub neej ua haujlwm ntev tshaj li 20 xyoo tom qab kev tsim kho tau txais kev tso cai txog tam sim no.Raws li cov kev hloov pauv hauv ntiaj teb no, cov neeg siv uas ua haujlwm thiab tswj cov nkoj yuav tsum tam sim no txiav txim siab nyuaj dua li yav dhau los txog kev pheej hmoo ntawm kev lag luam cuam tshuam nrog decarbonization ntawm cov nkoj, thiab hom nkoj uas lawv yuav tsum tau yuav thaum lub sijhawm hloov mus rau xoom. carbon."

Nyob rau sab nraud ntawm nws cov emissions tsom, cov teeb meem tseem tshawb nrhiav yav tom ntej fluidics tsom xam, kev hloov pauv thiab hloov kho cov cai ntawm kev soj ntsuam nkoj thiab kev tsim kho, kev txhim kho corrosion ntxiv, thiab cov ntsiab lus IMO tsis ntev los no.
