Kua arotakehia tēnei tuhinga i runga anō i ngā tikanga me ngā kaupapa here ētita a Science X. Kua whakanuia e ngā ētita ngā āhuatanga e whai ake nei, me te whakarite anō hoki i te pono o ngā ihirangi:
He take nui te huringa āhuarangi e hiahia ana kia arohia e te ao whānui. Kei te whakawhanake ngā whenua o te ao i ngā kaupapa here hei whakaiti i ngā pānga o te mahana o te ao me te huringa āhuarangi. Hei tauira, kei te whakaaro te Kotahitanga o Ūropi i tētahi huinga aratohu whānui hei whakatutuki i te koretake o te āhuarangi i te tau 2050. Waihoki, ko te kaupapa matua o te European Green Deal ko te whakaiti i ngā tukunga hau kati kōtuhi.
Ko te hopu i te hauhā waro (CO2) e tukuna ana, me te huri i roto i ngā matū hei hua arumoni whai hua, tētahi huarahi hei whakawhāiti i te mahana o te ao me te whakaiti i ōna pānga. Kei te tūhuratia e ngā kaipūtaiao te hangarau hopu me te whakamahi waro (CCU) hei huarahi whai hua hei whakawhānui ake i te rokiroki me te tukatuka waro hauhā i te utu iti.
Heoi, ko te nuinga o ngā rangahau CCU o te ao e whakawhāitihia ana ki te tata ki te 20 ngā matū whakaputa. I runga i te kanorau o ngā pūtake tukunga CO2, he mea nui te wātea mai o te whānuitanga o ngā matū, ā, me nui ake te rangahau hōhonu mō ngā tukanga ka taea te huri i te CO2 ahakoa i ngā kukū iti.
Kei te whakahaerehia e te rōpū kairangahau mai i Te Whare Wānanga o Chung-Ang o Korea he rangahau mō ngā tukanga CCU e whakamahi ana i ngā para, i ngā rauemi taiao whai rawa rānei hei rauemi mata, kia whai hua ai i te taha ōhanga.
Nō nā tata nei i whakaputa ai tētahi rōpū rangahau i arahina e Ahorangi Sungho Yoon me Ahorangi Tuarua Chul-Jin Lee tētahi rangahau e matapaki ana i te whakamahinga o te hauhā waro ahumahi me te dolomite, he toka parataiao noa, he nui te konupūmā me te konupora, hei whakaputa i ngā hua pea e rua mō te arumoni: te konupūmā formate me te konupora waikura.
"Kei te piki haere te hiahia ki te whakamahi i te hauhā waro hei whakaputa hua whai hua hei āwhina i te whakaiti i ngā pānga o te huringa āhuarangi, me te whakaputa hua ōhanga hoki. Mā te whakakotahi i ngā tauhohenga hauwai waro me ngā tauhohenga whakawhiti kationi, kua whakawhanakehia e mātou he tikanga mō te purenga i ngā waikura me ngā tukanga whakarewa i te wā kotahi hei whakaputa i ngā hanganga whai hua," te kōrero a Ahorangi Yin.
I roto i tā rātou rangahau, i whakamahia e ngā kaipūtaiao tētahi whakakorikori (Ru/bpyTN-30-CTF) hei tāpiri i te hauwai ki te hauhā waro, ā, e rua ngā hua tāpiri uara i puta mai: te konupūmā formate me te konupūmā waikura. Ko te konupūmā formate, he tāpiri sima, he deicer, me te tāpiri kai kararehe, e whakamahia ana hoki i roto i te whakakorikori hiako.
He rerekē, he whānuitia te whakamahinga o te konupūmā waikura i roto i ngā ahumahi hanga me ngā ahumahi rongoā. Ehara i te mea ka taea noa iho tēnei tukanga, engari he tino tere hoki, ka puta te hua i roto i te 5 meneti noa iho i te pāmahana rūma. Hei tāpiri, e whakatau ana ngā kairangahau ka taea e tēnei tukanga te whakaiti i te kaha o te mahana o te ao mā te 20% ki te whakataurite ki ngā tikanga tuku iho o te whakaputa konupūmā formate.
Kei te aromatawai hoki te tīma mēnā ka taea e tā rātou tikanga te whakakapi i ngā tikanga whakaputa o nāianei mā te ako i tōna pānga ki te taiao me te oranga ōhanga. "I runga i ngā hua, ka taea e mātou te kī he huarahi pai ki te taiao tā mātou tikanga hei whakakapi i te hurihanga waro hauhā ka taea te whakakapi i ngā tikanga tuku iho me te āwhina ki te whakaiti i ngā tukunga waro hauhā ahumahi," te whakamārama a Ahorangi Yin.
Ahakoa te ahua pai o te hurihanga o te hauhā waro hei hua whai hua, ehara i te mea ngāwari te whakanui ake i ēnei tukanga. Kāore anō kia hokohokohia te nuinga o ngā hangarau CCU nā te mea he iti te whaihua o ō rātou āhuatanga ōhanga ki te whakataurite ki ngā tukanga arumoni matua. "Me whakakotahi tātou i te tukanga CCU me te hangarua para kia whai hua ai mō te taiao me te ōhanga. Mā tēnei pea ka āwhina i te whakatutuki i ngā whāinga tukunga kore-kore ā muri ake nei," te whakatau a Tākuta Lee.
