Te Wetewete i te Pūngao Whakahou mā ngā Hangarau Pūhiko Matatau
I te kaha haere o ngā mahi a te ao ki te whawhai ki te huringa āhuarangi, kei te puta ake ngā putanga hou o te hangarau pākahiko hei mea nui mō te whakaurunga o te pūngao hou me te tango waro. Mai i ngā otinga rokiroki tauine-pūnaha ki ngā waka hiko (EV), kei te tautuhi anō ngā pākahiko o te whakatupuranga e whai ake nei i te pumau o te pūngao me te aro atu ki ngā wero nui o te utu, te haumaru, me te pānga ki te taiao.
Ngā Huarahi Hou i roto i te Matū Pūhiko
Kei te hurihia te whenua e ngā whanaketanga hou o ngā matū pākahiko rerekē:
- Ngā Pūhiko Rino-KonutaiE whakaatu ana te pākahiko rino-konutai a Inlyte Energy i te 90% o te pai o te haere me te hoki mai, ā, e mau tonu ana te kaha mō ngā huringa neke atu i te 700, e tuku ana i te rokiroki iti te utu, roa hoki mō te pūngao o te rā me te hau.
- Ngā Pūhiko Āhua-TūMā te whakakapi i ngā irahiko wai mura ki ngā mea totoka, ka whakarei ake ēnei pākahiko i te haumaru me te kiato o te pūngao. Ahakoa kei te mau tonu ngā arai tauine, ko tō rātou pūmanawa i roto i ngā EV—te whakanui ake i te tawhiti me te whakaiti i ngā mōrearea ahi—he mea whakarerekē.
- Ngā Pūhiko Lithium-Whawhā (Li-S)Me te nui atu o ngā mātotoru pūngao ariā i te lithium-ion, e whakaatu ana ngā pūnaha Li-S i te tumanako mō te rererangi me te rokiroki whatunga. Kei te aro atu ngā auahatanga i roto i te hoahoa irahiko me te hanganga irahiko ki ngā wero o mua pērā i te whakawhiti polysulfide.
Te Whakatau i ngā Wero o te Oranga Tonutanga
Ahakoa te ahunga whakamua, ko ngā utu taiao o te keri konukōre e whakaatu ana i ngā hiahia nui mō ngā huarahi kē atu matomato:
- He nui ngā rauemi wai e pau ana i te tango konukōre tuku iho (hei tauira, ngā mahi tote o Atacama i Chile) ā, e ~15 tana o te CO₂ e tukuna ana mō ia tana o te konukōre.
- Nō nā tata nei i whakatinanahia e ngā kairangahau o Stanford tētahi tikanga tango hikohiko, e whakaiti ana i te whakamahinga wai me ngā tukunga, me te whakapai ake hoki i te whai huatanga.
Te Putanga Ake o ngā Huarahi Kōwhiringa Nui
Kei te piki haere te rongonui o te konutai me te pāhare pāporo hei whakakapi pumau:
- He rite te kaha o ngā pākahiko konutai-ion ki te lithium-ion i raro i ngā pāmahana tino kino, e whakaatu ana te Physics Magazine i tō rātou tere whanaketanga mō ngā EV me te rokiroki whatunga.
- He pai te pumau o ngā pūnaha pāhare pākawa-ion, ahakoa kei te haere tonu ngā whakapainga ki te mātotoru o te pūngao.
Te Whakaroa i te Huringa Ora o te Pūhiko mō te Ōhanga Porowhita
I te mea e pupuri ana ngā pākahiko EV i te 70–80% o te kaha i muri i te whakamahinga o te waka, he mea nui te whakamahi anō me te hangarua:
- Ngā tono mō te oranga tuaruaKa whakakahangia te rokiroki pūngao kāinga, arumoni rānei e ngā pākahiko EV kua reti, ā, ka ārai i te wā whakatārewatanga o te pūngao whakahou.
- Ngā Auahatanga HangaruaKo ngā tikanga matatau pēnei i te whakaora hydrometallurgical inaianei ka tangohia pai te lithium, te cobalt, me te nickel. Heoi, e 5% noa iho o ngā pākahiko lithium e hangaruahia ana i ēnei rā, he iti iho i te reiti 99% o te waikawa mata.
- Ko ngā kaupapa here pēnei i te ture Whānui mō te Kawenga Kaihanga (EPR) a te EU e pupuri ana i ngā kaihanga ki te kawenga mō te whakahaere i te mutunga o te oranga.
Kaupapahere me te Mahi Tahi e Whakakaha ana i te Ahunga Whakamua
Kei te tere ake te whakawhiti i ngā kaupapa ā-ao:
- Mā te Ture Rauemi Mata Hira a te EU ka whakarite te pakari o te mekameka tuku me te whakatairanga anō hoki i te hangarua.
- Ko ngā ture hanganga o Amerika e tautoko ana i te R&D pākahiko, e whakatairanga ana i ngā hononga tūmatanui-tūmataiti.
- Mā ngā rangahau maha-mātauranga, pērā i te mahi a MIT mō te koroheketanga o te pākahiko me te hangarau tangohanga a Stanford, ka honoa te ao mātauranga me te ahumahi.
Te anga atu ki tētahi Pūnaha Pūngao Tauwhiro
Ko te ara ki te kore-pūtea e hiahia ana kia nui atu i ngā whakapainga ā-whāiti. Mā te whakatairanga i ngā matū e whai hua ana ki ngā rauemi, ngā rautaki huringa ora porowhita, me te mahi tahi o te ao, ka taea e ngā pākahiko o te whakatupuranga hou te whakakaha i tētahi heke mai ma ake—te whakataurite i te haumarutanga pūngao me te hauora o te ao. E ai ki tā Clare Grey i whakanui i roto i tana kauhau MIT, "Ko te heke mai o te hiko e whakawhirinaki ana ki ngā pākahiko ehara i te mea he kaha anake, engari he pumau i ia wāhanga."
E whakaatu ana tēnei tuhinga i ngā whakaritenga rua: te whakanui ake i ngā otinga rokiroki auaha me te whakauru i te oranga tonutanga ki roto i ia watt-haora e whakaputaina ana.
