Hangarau Hou i roto i ngā Pūngao Pūngao Geothermal
Ko te pūngao waiariki tētahi o ngā pūtake pūngao whakahou tino pumau, ki te whakaritea ki te rā me te hau. E wātea ana te wera waiariki 24 hāora ia rā, kāore e whakawhirinaki ki te rangi, ā, he iti noa te tapuwae waro. Heoi, ehara i te mea ngāwari te whakamahi: kāore i te ōrite te wāhi o ngā pūtake wera, he nui ngā utu keri, ā, ko ngā wero hangarau ko te waikura, te tauine (te maturuturunga o te kohuke), me te whakahaere wai o raro i te mata. I ngā tau tata nei, kua tere te whanaketanga o te auahatanga i te taha whakaputa hiko me te mekameka hurihanga pūngao waiariki katoa. Ka tūhuratia e tēnei tuhinga ngā hangarau hou e hanga ana i ngā tipu hiko waiariki kia pai ake, kia ngāwari ake, kia taea hoki i roto i ngā wāhi maha atu.
1) Huringa Rua o te Whakatipuranga Hou: Te ORC me te Kalina e Tino Whai Hua Ana
I roto i te maha o ngā mara waiariki, kāore i te tino teitei ngā pāmahana wai hei whakaputa i te mamaoa maroke e pai ana mō ngā tāwhana mamaoa tikanga. Koinei te wāhi e whai wāhi mai ai ngā tipu hiko huringa rua. Ka whakawhitihia e te hangarau rua te wera mai i te wai tote waiariki ki tētahi wai mahi tuarua, he iti te kohua (pēnei i te isobutane, te isopentane, ētahi ranunga rānei), ka peia he tāwhana.
Ko ngā whanaketanga hou o te Organic Rankine Cycle (ORC) ko:
– He hoahoa whakawhiti wera kiato ake, he whai hua ake hoki, pērā i ngā whakawhiti wera pereti, ngā whirihoranga rānei e whakanui ake ana i te tauwehenga whakawhiti wera me te whakaiti i te paru.
– He pai ake ngā tāpine iti-tere-rahi mō ngā pūtake wera reo-iti, kia iti ake ai te ohanga o ngā kaupapa ā-pūrua 1–10 MW.
– Te arotau i te whakahaere me te mahi taurangi, e āhei ai te tipu ki te urutau ki ngā huringa o te tere rere o te tote me te pāmahana me te kore e nui te ngaronga o te whai huatanga.
Haunga te ORC, kei te whakapai tonuhia te Huringa Kalina (e whakamahi ana i te ranunga haukini-wai) nā tōna kaha ki te hopu pūngao i ngā pāmahana iti me te whai huatanga pai. Ko ngā wero kei roto i te uaua o te pūnaha me ngā rauemi me tu atu ki ngā āhuatanga matū motuhake. Ko ngā rangahau hou e arotahi ana ki te whakapai ake i te pono, te whiriwhiri rauemi, me te whakahaere i te hanganga ranunga kia pumau ai te mahi.
2) Ngā Tāpine me ngā Hanga Pūkaha: Ngā Rauemi me ngā Hoahoa Matatau e Ātete Ana ki ngā Taiao Waikura
Ko te taha "whakaputa hiko" o te pūngao waiariki ehara i te mea ko te kaiwhakaputa hiko anake, engari ko te tāpine e whakakaha ana i a ia. Tērā pea kei roto i te mamaoa waiariki me te wai tote te H₂S, te CO₂, te pūhaumāota, te silica, me ngā kohuke maha ka taea te whakatō me te waikura.
Ko ngā mahi auaha matua ko:
– Ngā rauemi me ngā paninga ārai-waikura me te ārai-horo i runga i ngā mata o te tāpine, ngā anga, me ngā wāhanga takirere. Mā te hangarau rehu wera, ngā paninga nikara, me ētahi rauemi hiato ka roa ake te ora o te mahi.
– Ngā hoahoa tāpine e manawanui ake ana ki ngā "paru", hei tauira, ko te āhua o te mata e whakaiti ana i ngā wāhi e ngawari ana te putunga, me te pūnaha wehewehe pata whai hua ake (wehe makuku) mō te mamaoa mākū.
– Kua whakapaitia te pūnaha whakaputa hiko tukutahi me te pūnaha whakamatao kia mau tonu ai te pumau o te whakaputa hiko i ngā kawenga teitei i roto i ngā āhuatanga wera me te makuku e kitea ana i ngā rohe waiariki.
Ko te mutunga mai he iti ake te wā kore mahi, he pumau ake te whai huatanga, me te whakahaere pai ake i ngā utu whakahaere me te tiaki.
3) Ngā Pūnaha Pūnaha Waiariki Whakarei Ake (EGS): Te Whakatuwheratanga i ngā Wāhi Hou mō ngā "Whakaputa" Pūnaha Waiariki
Ko tētahi putanga nui i roto i te umanga waiariki ko ngā Pūnaha Waiariki Whakarei (EGS). Ko te ariā: Mena he toka wera kei tētahi wāhi engari he iti te urunga (kāore i te nui te wai hei rere), ka hangaia ngā pakaru horihori hei hanga i tētahi "puna wai" mō te rere o te wai. Ka whakawhānui ake tēnei i te pūmanawa waiariki ki ngā wāhi kāore i wātea i mua.
E hiahiatia ana e te EGS:
– He hangarau whakaohooho puna wai tino tika ake (hei tauira, te whakaohooho waipēhi).
– Te aroturukitanga rū whenua iti-tūturu hei whakahaere i ngā mōrearea rū whenua i puta mai.
– Te whakatauira i te puna wai me te matapae rere mā te whakamahi i ngā whakatauira tau tika ake.
I te pakeketanga o te EGS, me te whakaaetia e ngā ture, ka taea te hanga i ngā "whakaputa hiko" waiariki tata ki ngā pokapū kawenga hiko, me te kore e whakawhirinaki ki ngā puna hiko tūturu motuhake.
4) Ngā Pūngao Ā-Wāhi: Te Whakaiti i te Mōrearea me te Uaua o te Wai
He hangarau e tipu haere ana ko te waiariki porowhita-katia. He rerekē ki ngā pūnaha tuku iho e pupuhi ana i te wai tote mai i raro i te whenua, ka hurihia e te waiariki porowhita-katia he wai mahi i roto i tētahi paipa kati e kukume ana i te wera mai i te toka wera me te kore e pā tika ki te wai tote.
Ngā painga:
– Ka tino whakaitihia te mōrearea o te kōpeketanga me te waikura nā te wai tote.
– Ka whakaiti i te koretake e pā ana ki te hototahitanga o ngā matū wai.
– He pai pea te whakamahi i ngā wāhi kāore i te nui ngā puna wai wera.
Ko te wero ko te whakarite kia nui te whakawhiti wera kia whai hua ai te kaupapa i roto i te taha ōhanga. Nō reira, ko ngā mahi auaha e arotahi ana ki te hoahoa āhuahanga o ngā puna, ki ngā rauemi paipa kawe-teitei, me te arotau i te tere o te tohanga wai. Mēnā ka angitu, ka taea e ngā pūnaha porowhita-kati te whakateretere i te hanganga o ngā tipu hiko geothermal modular.
5) Te Toka Wera Rawa me te Pūngao Whenua Tino Pāmahana: He Peke Nui ki te Whai Hua
Ko tētahi o ngā rohe tino nui ko te geothermal tino wera (ngā toka tino wera, ka eke ki te pāmahana neke atu i te 374°C, ka tata atu, ka nui atu rānei i te pāmahana tino whakahīhī o te wai). He nui ngā mātotoru me ngā enthalpies o ngā wai tino whakahīhī, ka taea ai e rātou te whakaputa i te kaha nui ake mō ia puna.
Ko ngā hangarau matua ko:
– Ngā tikanga keri pāmahana tino wera me ngā rauemi anga e ātete ana ki te wera.
– Ngā pūoko hohonu e kaha ana ki te mahi pumau i ngā pāmahana tino tiketike.
– Ngā rautaki hanga haumaru me te werohanga anō hei ārai i te hekenga tere o te mahi a ngā puna wai.
Ki te wikitoria i ēnei wero hangarau, ka taea e ngā tipu hiko waiariki te whakatutuki i te kaha o te hiko e tata ana ki ērā o ngā tipu hiko wahie pūmua tuku iho, engari he iti ake ngā tukunga.
6) Auahatanga Keri: He iti ake ngā utu, he tere ake ngā kaupapa
Ahakoa e aro ana tēnei tuhinga ki ngā "whakaputa hiko", ko te mea pono ko te keri he nui te pānga o ngā utu hiko waiariki ki te keri. Nō reira, ka pā tika te hangarau keri hou ki te oranga tonutanga o te tipu.
Ngā whanaketanga nui:
– Te keri anga whakamua me ngā puna maha-taha hei "horoi" i tētahi wāhi puna whānui mai i te wāhi kotahi.
– Ngā mata PDC me ngā rauemi mata wiri he ātete ake ki te pakū i roto i ngā toka mārō.
– Te keri e ahu mai ana i ngā raraunga: he tātaritanga wā-tūturu hei ārai i te piri o te paipa, hei arotau i te taumaha ki runga i te mata, hei whakateretere hoki i ngā reiti urunga.
– Ngā whakamātautau i ngā hangarau keri hou (hei tauira, ngā huarahi wera, ngā huarahi rerekē rānei) e aro ana ki te whakaiti nui i ngā utu.
Mā te tere me te iti o te utu o te keri, ka taea e ngā kaupapa waiariki te eke ki te taumata arumoni.
7) Te Whakamatihiko me te AI: "Te Whare Hiko Pūngao Atamai"
Kei te neke haere ngā tipu waiariki o ēnei rā ki ngā mahi e whakahaerehia ana e ngā raraunga. Inaianei kua honoa ngā pūoko, ngā pūnaha SCADA, me ngā pūnaha hītori ki te AI me te ako mīhini hei:
– Te tiaki matapae: te matapae i te pakaru o te peera, te papu, te tāpine rānei i mua i te puta.
– Arotauhia ngā tautuhinga o ngā whakawhiti wera, ngā wehewehe, me ngā whakapūmau mō te putanga nui me te iti rawa o te whakamahinga pirinoa.
– Te aro turuki i te tauine me te waikura mā te whakakotahi i te matū wai, te pāmahana, te pēhanga, me ngā raraunga mahi taputapu.
Kei te tīmata hoki te whakamahi i ngā māhanga mamati—ngā tauira mariko o ngā tipu hiko me ngā puna wai—hei whakamātautau i ngā horopaki whakahaere me te kore e whakararuraru i te pūnaha tūturu.
8) Te Whakaurunga ki te Rokiroki me te Whakamahinga Wera (Whakaputa-tahi)
Ehara i te mea ko te hiko anake te mea e whaia ana e te hangarau hou, engari he uara tāpiri anō hoki:
– Te whakaputanga tahi (CHP): ka whakamahia te wera toenga mō te whakamaroke i ngā hua ahuwhenua, te whakamahana rohe, ngā tukanga ahumahi, ngā whare kati kōtuhi rānei.
– Te whakaranu: te whakakotahitanga o te waiariki me te waiariki o te rā, te koiora rānei hei whakanui ake i te ngāwari.
– Te penapena pūngao wera hei whakahaere i te putanga me te whakanui ake i te kaha ki te whai i te kawenga, ahakoa kua noho kē te waiariki hei kawenga taketake.
Ka whakanui ake tēnei huarahi i te kaha ōhanga, ā, ka whakakaha ake hoki i te tūranga o te waiariki i roto i te whakawhiti pūngao.
Whakamutunga
Kei te neke haere ngā hangarau hou o ngā kaihanga hiko waiariki i ngā taha maha: ko ngā huringa rua ORC/Kalina e piki haere ana te whai hua, ko ngā rauemi tāpoi me ngā kaihanga hiko e ātete ana ki te waikura, me ngā huarahi hou pēnei i te EGS me te porowhita kati kei te whakawhānui ake i ngā wāhi whanaketanga. I te taha o ngā auahatanga keri me te mamati e peia ana e te AI, kei te piki haere te pono, te āhua rerekē, me te whakataetae o ngā tipu hiko waiariki. I ngā tekau tau e haere ake nei, mā te whakakotahitanga o te hiko waiariki tino wera, te hoahoa pūnaha atamai ake, me te whakamahinga wera whakauru ka taea te hanga i te hiko waiariki hei pou matua o te hiko ma—he pumau, he iti te tukunga, ā, he rite ki te tautoko tonu i ngā hiahia hiko me te wera ahumahi.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga ki te horopaki o Initonīhia (te porowhita ahi pea, ngā wero raihana, me ngā tauira o te whakatinanatanga o te mara) me te tāpiri atu rānei i tētahi rārangi tohutoro me ngā raraunga tau (te whai huatanga, te awhe pāmahana, me ngā utu).
