He aha i wera whakarere ai te hanga hauwai mai i te mana karihi?

I ngā wā o mua, nā te kaha o te pānga mai o te hau kino, kua whakaroa ngā whenua i ā rātou mahere hei tere ake i te hanganga o ngā tipu karihi me te whakaiti i te whakamahinga o aua tipu. Engari i te tau kua hipa, kua piki haere anō te kaha karihi.

I tētahi taha, kua arahina e te pakanga o Rūhia-Ukraine ngā panonitanga ki te mekameka tuku pūngao katoa, ā, kua akiaki hoki i te tini o ngā "kaiwhakarērea karihi" ki te whakarērea tetahi i muri i tetahi, me te whakaiti i te hiahia katoa mō te pūngao tuku iho mā te tīmata anō i te mana karihi.

Ko te hauwai, i tētahi atu taha, he mea nui ki ngā mahere hei tango i te waro o ngā ahumahi taumaha i Ūropi. Nā te tipu haere o te mana karihi i whakatairanga hoki i te mōhiotanga o te hanga hauwai e te pūngao karihi i ngā whenua o Ūropi.

I te tau kua hipa, i roto i tētahi tātaritanga a te OECD Nuclear Energy Agency (NEA) ko "The Role of Nuclear Power in the Hydrogen Economy: Cost and Competitiveness" i whakatau ko te tumanako ka whakamahia te mana karihi i roto i te ōhanga hauwai he whai wāhitanga nui mēnā ka tangohia ngā kaupapa tika.

I kōrero a NEA me whakapiki ake te rangahau me te whanaketanga hei whakapai ake i te whai huatanga o te hanga hauwai i roto i te wā waenga, nā te mea "ko te pyrolysis methane, ko te huringa matū hydrothermal rānei, me te whakakotahi pea me te hangarau tauhohenga o te whakatupuranga tuawhā, he kōwhiringa waro-iti e whai hua ana ka taea te whakaiti i te hiahia pūngao tuatahi mō te hanga hauwai".

E mārama ana ko ngā painga matua o te mana karihi mō te hanga hauwai ko te iti o ngā utu hanga me te whakaiti i ngā tukunga. Ahakoa ka hangaia te hauwai matomato mā te whakamahi i te pūngao whakahou i te tauwehenga kaha o te 20 ki te 40 ōrau, ka whakamahia e te hauwai māwhero te mana karihi i te tauwehenga kaha o te 90 ōrau, ka whakaiti i ngā utu.

Ko te whakatau matua a NEA ko te kaha o te mana karihi ki te whakaputa i ngā warowaihā iti i runga i te tauine nui i te utu whakataetae.

Hei tāpiritanga, kua whakaarohia e te International Atomic Energy Agency tētahi mahere mahi mō te whakatinanatanga arumoni o te hanga hauwai karihi, ā, e whakapono ana te umanga kei te haere tonu te hanganga o tētahi turanga ahumahi me te mekameka tuku e pā ana ki te hanga hauwai karihi.

I tēnei wā, kei te kaha te rangahau me te whakawhanake i te kaupapa whakaputa hauwai pūngao karihi a ngā whenua whakawhanake nui o te ao, me te ngana ki te uru atu ki te hapori ōhanga pūngao hauwai i te wā e taea ai. Kei te kaha te whakatairanga a tō tātou whenua i te whanaketanga o te hangarau whakaputa hauwai mai i te pūngao karihi, ā, kua uru ki te wāhanga whakaaturanga arumoni.

Mā te hanga hauwai mai i te pūngao karihi mā te whakamahi i te wai hei rauemi mata, ehara i te mea ka kore noa e tukuna he waro i roto i te tukanga hanga hauwai, engari ka whānui ake hoki te whakamahinga o te pūngao karihi, ka whakapai ake i te whakataetae ōhanga o ngā tipu hiko karihi, ka waihanga hoki i ngā āhuatanga mō te whanaketanga taurite o ngā tipu hiko karihi me te pūngao whakahou. Ka taea e ngā rauemi wahie karihi e wātea ana mō te whanaketanga i runga i te whenua te whakarato i te pūngao neke atu i te 100,000 ngā wā nui atu i ngā wahie pūmua. Mā te whakakotahitanga o ngā mea e rua ka whakatuwhera i te ara mō te whanaketanga tauwhiro me te ōhanga hauwai, ā, ka whakatairanga i te whanaketanga matomato me te noho ora. I roto i te āhuatanga o nāianei, he whānui ngā tirohanga tono. Arā, ko te hanga hauwai mai i te pūngao karihi he wāhanga nui pea o te heke mai o te pūngao ma.;
