He rite te hanganga o te ngira kōka, ā, he mea hanga ki te hinu para mai i ngā whare hanga hinu, ki te hinu waro rānei. Koinei te rauemi mata matua mō te hanga i ngā irahiko karāpeti e whakamahia ana i roto i te tukanga hanga maitai mā te whakamahi i te oumu pewa hiko (EAF). Ka whakaarohia e tēnei tātaritanga mākete kōka ngā hoko mai i te umanga karāpeti, te umanga pākahiko, me ētahi atu. Ka whakaarohia hoki e tā mātou tātaritanga ngā hoko o te kōka karāpeti i APAC, Europe, Amerika Te Raki, Amerika Te Tonga, me te MEA. I te tau 2018, he nui te wāhi mākete o te wāhanga ahumahi karāpeti, ā, e matapaetia ana ka haere tonu tēnei ia i roto i te wā matapae. Ko ngā āhuatanga pēnei i te pikinga ake o te tono mō ngā irahiko karāpeti mō te tikanga EAF o te hanga maitai ka whai wāhi nui ki te wāhanga ahumahi karāpeti hei pupuri i tōna tūranga mākete. Waihoki, ka tirohia e tā mātou pūrongo mākete kōka karāpeti o te ao ngā āhuatanga pēnei i te pikinga ake o te kaha hanga hinu, te pikinga ake o te whakamahi i ngā waka matomato, te pikinga ake o te tono mō ngā irahiko karāpeti UHP. Heoi, ko te whānui haere o ngā wero i waenganui i te tono me te tuku konukōre e pā ana ki te kawe haumi ki te umanga waro nā runga i ngā ture e ārai ana i te parahanga waro, te piki me te heke o ngā utu hinu mata me te waro, ka ārai pea i te tipu o te umanga ngira kōka i roto i te wā matapae.
Mākete Koka Ngira o te Ao: Tirohanga Whānui
Te pikinga ake o te hiahia mō ngā hiko karāhe UHP
E whakamahia ana ngā irahiko karāpiti i roto i ngā mahi pēnei i ngā oumu pewa ruku me ngā oumu koko mō te hanga maitai, ngā rauemi kore-whakarewa, me ngā konganuku. E whakamahia ana hoki ēnei i roto i ngā EAF mō te hanga maitai. Ka taea te hanga i ngā irahiko karāpiti mā te whakamahi i te kōka hinu, te kōka ngira rānei. Ka whakarōpūtia ngā irahiko karāpiti ki te mana noa, te mana teitei, te mana tino teitei, me te UHP i runga i ngā tawhā pēnei i te ātete, te kawe hiko, te kawe wera, te ātete ki te waikura me te ru wera, me te kaha miihini. I roto i ngā momo irahiko karāpiti katoa, kei te arohia ngā irahiko karāpiti UHP i roto i te umanga maitai. Mā tēnei tono mō ngā irahiko UHP ka whānui ake te mākete kōka ngira o te ao i te CAGR o te 6% i roto i te wā matapae.
Te putanga mai o te maitai matomato
Ko te tukunga o te CO2 he take nui e pā ana ki te umanga maitai o te ao katoa. Hei whakatau i tēnei take, he maha ngā mahi rangahau me te whanaketanga (R&D) kua mahia. Nā ēnei mahi R&D i puta ai te maitai matomato. Kua kitea e ngā kairangahau tētahi tukanga hanga maitai hou ka taea te whakakore katoa i ngā tukunga CO2. I roto i te tukanga hanga maitai tuku iho, i te wā e hanga ana te maitai, ka tukuna he nui te paoa, te waro, me te mura pupuhi. Ko te tukanga hanga maitai tuku iho ka tukuna te CO2 e rua te taumaha o te maitai. Heoi, ka taea e te tukanga hou te whakatutuki i te hanga maitai me te kore tukunga. Ko te werohanga waro paura me te hangarau hopu me te rokiroki waro (CCS) ētahi o aua mea. E matapaetia ana ka whai pānga pai tēnei whanaketanga ki te tipu whānui o te mākete.
Whenua Whakataetae
Nā te aroaro o ētahi kaitākaro nui, kua tino kaha te mākete ngira kōka o te ao.
