Udaba luhlanganisa imizamo eSikhungweni Sokuhlela Nokuklama Semikhumbi Eluhlaza (GSC), ukuthuthukiswa kwezinhlelo zokuthwebula i-carbon ebhodini, kanye namathemba omkhumbi kagesi obizwa ngokuthi i-RoboShip.
Ku-GSC, u-Ryutaro Kakiuchi uchaze ngentuthuko yakamuva yokulawula ngokuningiliziwe futhi ubikezela izindleko zamafutha ahlukahlukene aphansi kanye ne-zero-carbon kuze kube ngu-2050. Ngokubheka uphethiloli we-zero-carbon emikhunjini ehamba olwandle, u-Kakiuchi ugqamisa i-ammonia eluhlaza njengenzuzo kakhulu. Uphethiloli we-zero-carbon ngokwezindleko zokukhiqiza ezicatshangwayo, nakuba uphethiloli okhishwa yi-N2O kanye nokusingatha ukukhathazeka.
Imibuzo yezindleko nokuhlinzeka izungeza amafutha okwenziwa e-carbon-neutral afana ne-methanol ne-methane, kanye namalungelo okukhishwa kwe-CO2 athathwe kugesi adinga ukucaciswa kuyilapho ukuhlinzeka kuyiyona nto ekhathaza kakhulu ngama-biofuels, nakuba izinhlobo ezithile zezinjini zingasebenzisa ama-biofuels njengophethiloli wokushayela.
Ibhekisela endaweni yamanje yokulawula, yezobuchwepheshe kanye nekaphethiloli njengokungaqiniseki kanye nesithombe “se-opaque” yesikhathi esizayo, i-GSC yize kunjalo isibeke isisekelo semiklamo yemikhumbi eluhlaza yesikhathi esizayo, okuhlanganisa ne-panamax yokuqala yase-Japan ephehlwa yi-ammonia eyanikezwa i-AiP ekuqaleni kwalo nyaka.
“Nakuba i-ammonia eluhlaza kubikezelwa ukuthi izobiza kancane phakathi kwezibaseli ezihlukene ze-zero-carbon, kucatshangwa ukuthi amanani asazoba phezulu kakhulu kunalawo amafutha emikhumbi akhona manje,” kusho umbiko.
“Ngokombono wokuqinisekisa ukushintshwa kwamandla okushelelayo, kukhona nemibono eqinile evuna izibaseli zokwenziwa (i-methane ne-methanol) ngoba lawa mafutha angasebenzisa ingqalasizinda ekhona.Ngaphezu kwalokho, emizileni yebanga elifushane, inani eliphelele lamandla adingekayo lincane, liphakamisa ukuthi kungenzeka ukusebenzisa i-hydrogen noma amandla kagesi (amaseli kaphethiloli, amabhethri, njll.).Ngakho, izinhlobo ezahlukene zikaphethiloli kulindeleke ukuthi zisetshenziswe esikhathini esizayo, kuye ngomzila nohlobo lomkhumbi.”
Umbiko uphinde waxwayisa ngokuthi ukwethulwa kwezinyathelo zokuqina kwekhabhoni kungase kufinyeze isikhathi sokuphila esilindelekile semikhumbi njengoba uguquko lwe-zero carbon ludlala.Isikhungo sisaqhubeka nokufunda izixazululo ezihlongozwayo emzamweni wokujulisa ukuqonda kwaso nokwazisa amakhasimende, sithe.
"Izinguquko ezididayo ezinkambisweni zomhlaba eziqondise ekuzuzeni ukukhishwa kwe-zero ka-2050, okuhlanganisa nezinyathelo zokulawula, zilindeleke esikhathini esizayo, futhi ukuqwashisa okuphezulu kwenani lemvelo lokuchithwa kwe-carbonization kwandisa ingcindezi yokwamukela izindinganiso zokuhlola eziphambene nokusebenza kahle komnotho.Kungenzeka futhi ukuthi ukwethulwa kohlelo lokulinganisa lwe-CII kuzoba nomthelela ongathi sína okhawulela impilo yomkhiqizo wemikhumbi, nakuba impilo ende yokusebenza yeminyaka engaphezu kwengama-20 ngemva kokwakhiwa kuthathwe kalula kuze kube manje.Ngokusekelwe kulezi zinhlobo zamathrendi emhlabeni jikelele, abasebenzisi abasebenzisa futhi baphathe imikhumbi manje kufanele benze izinqumo ezinzima kakhulu kunangaphambili mayelana nezingozi zebhizinisi ezihlobene nokukhipha ikhabhoni yemikhumbi, kanye nezinhlobo zemikhumbi okufanele bayithenge ngesikhathi soshintsho iye kuqanda. carbon.”
Ngaphandle kokugxila kwayo ekukhiqizweni, izingqinamba ziphinde zihlole ukuhlaziywa kwe-fluicics okuzayo, izinguquko nezibuyekezo zemithetho yokuhlola umkhumbi nokwakhiwa, izengezo zokugqwala, nezihloko zakamuva ze-IMO.
