Kushandiswa kwegirinhi methanol, kabhoni-neutral mafuta anowanikwa kubva kune anogona kuvandudzwa (biomass uye solar simba, semuenzaniso), inobvumira Maersk's matsva masere mega-containers (AP Moller-Maersk) kuburitsa anosvika miriyoni matani isingasviki CO2 per. gore. Muna 2020, Maersk yakaburitsa mamirioni makumi matatu nematatu e CO2.
Zvikepe zvitsva, izvo zviri kuvakwa muSouth Korea, neHyundai Heavy Industries - Hyundai haingogadziri mota -, kana zvese zvikafamba sezvakarongwa, zvichaunzwa mukutanga kwe2024 uye ichange iine simba rezita rekutenderedza zviuru gumi nematanhatu zvemidziyo. TEU) imwe neimwe.
Zvikepe zvisere zvitsva zvemabhokisi chikamu chehurongwa hwekuvandudza ngarava dzeMaersk uye hurongwa hwayo hwekuwana kusarerekera kabhoni muna 2050 kune hombe yepasirese inotakura maritime, nechibvumirano chakasainwa neHyundai Heavy Industries kuti ichine sarudzo yekuwedzera ngarava ina kuti dzivakwe panosvika 2025. .
Pamusoro pechinangwa chayo chemukati chekuve kabhoni kusarerekera panosvika 2050, Maersk iri kupindurawo kune zvinodiwa nevatengi vayo. Inopfuura hafu yevatengi vepamusoro mazana maviri veMaersk, kwatinowana mazita akaita seAmazon, Disney kana Microsoft, vari kuisawo zvibodzwa zvekudzikisa emission pamaketani avo ekupa.
Dambudziko guru harisi injini.
Injini dzedhiziri dzinozoshongedzera ngarava idzi dzichakwanisa kumhanya kwete chete pagirinhi methanol, asiwo pamafuta anorema, iwo echinyakare mafuta ezvikepe zvezvikepe izvi, kunyangwe iye zvino aine yakaderera sarufa yemukati (kudzora kuburitswa kwesarufa inokuvadza kwazvo. oxides kana SOx).Kuve nemukana wekushanda nemafuta maviri akasiyana kwaive kukosha kuchengetedza midziyo ichishanda, zvisinei nedunhu repasi ravanoshanda kana kuwanikwa kwegirinhi methanol, iyo ichiri kushomeka mumusika - kuwanikwa kwemafuta anovandudzwa uye ekugadzira. inokanganisawo mota yeindasitiri.
Iri ndiro dambudziko guru, anodaro Maersk: kuwana, kubva pazuva rekutanga, kupihwa kwehuwandu hunodiwa hwegirini methanol kuti ipe ngarava dzemidziyo yayo, sezvo kunyangwe ichingova "chete" zvikepe zvisere (zvakakura kwazvo), ivo vanozomanikidza kuwedzera zvakanyanya kugadzirwa kweiyi carbon neutral fuel. Nechinangwa ichi, Maersk yakagadzira uye yakatsvaga kumisikidza kudyidzana nekudyidzana nevatambi munzvimbo ino.
Kugona kweinjini idzi kumhanya pamafuta maviri akasiyana kuchaita kuti mutengo wemudziyo wega wega ukwire 10% kusvika 15% ukwire kupfuura zvamazuva ese, umire panosvika 148 miriyoni euros imwe neimwe.
Ichiri pagirinhi methanol, inogona kunge iri yekugadzira mavambo (e-methanol) kana kuti inogona kugadzirwa zvakachengetedzeka (bio-methanol), yakananga kubva kubiomass kana kuburikidza nekushandisa renewable haidrojeni, yakasanganiswa necarbon dioxide kubva mubiomass kana kubatwa kwecarbon dioxide.
Nhau dzakanaka dzeindasitiri yemotokari?
Hapana fungidziro. Kupinda kwe "hofori dzegungwa" mumafuta ekugadzira kana kuti anovandudzwa kuchave kwakakosha kupa chiyero icho chinoshaikwa ichi chinodiwa imwe nzira yefossil, izvo zvinogona kuita zvakanaka mukuderedza kuburitswa kwegasi rinopisa.
Injini dzinopisa mukati dzinogona "kuparara" mukufamba kwenguva, asi hazvireve kuti havakwanise kana kupawo zvakanaka mukuderedza kuburitswa.
