Kufamba kwezuva pazvibhorani

Reservoir inzvimbo huru, yakaenzana, yakavhurika, ine zuva, iyo inobatanidza nenzira, grid uye, pamvura yemagetsi dam, nesimba remagetsi. Kufamba kwephotovoltaics (FPV) kunoisa mapaneli ezuva emabhawa eplastiki anoramba achibva pasi kana kumahombekombe. Yakakura kubva pakunzwa kwechikwata chemakirowatt-skala pilots pakati pe2007 ne2013 kusvika kumaruva emazana emegawatts.

Mufananidzo wakarurama: **Kufamba kwezuva kunoshanda, kuri kutengesa uye kunodhura chete zvishoma kupfuura simba rezuva panyika; inokunda apo nyika isiri yakakwana kana ine kukosha uye uko kune chigaro chemvura nekubatana kwe grid. Zvimwe zvinodiwa, senge kutonhora kwezvimba uye kuchengetedza madziro, zviri pachena asi zvidiki uye hazvisi kunyatsoongororwa sezvavanoti mabrochure, uye njodzi dzakadai semvura yakaoma nemamiriro ekunze ndedzechokwadi. **

9,434 TWhgore kubva kusanganisira 30% ye114,555 maresitorendi pasi rese, pamusoro 30% yemagetsi epasi (Jin et al., 2023)

3% kusvika 6%kupfuura simba gore kubva kupisa mhedzisiro yemvura, yakaongororwa muNetherlands neSingapore (Dörenkämper et al., 2021)

Chii icho

A kutenderera solar plant ane maviri mativi: paneles uye inverters (sezvo panyika), floats (zvakajairika high-density polyethylene pontoons kuti kuchengetedza paneles pa low tilt), walkways yekuchengetedza, uye moorings: ropes, zvinyoronyoro uye anchors kana shore ties kuti chengetedza chitsuwa munzvimbo semvura mamiriro anokwira nekumhanya uye uswa inomanikidza pamusoro. Cables kuenderera mberi nefloats kune inverter pabank kana pane kutenderera platform.

Vazhinji mishonga iri kugara pamvura yakagadzirwa: hydropower uye mvura yekunwa-mahombekombe, kusvibisa mabwe, yakafukidzwa chipatara uye uchirima pits, sewage lagoons. Nearshore uye offshore kutenderera simba rezuva mumvura ndeye nyowani, yakanyanya kuoma sarudzo. World Bank’s market report yakafungidzira kuti pane 400,000 km² yemvura inochengetwa nevanhu pasi rose.

Maitiro ekushanda

Zvimwe zvemapaneli, zvimwe zvezuva. A floating panel inoita magetsi sezvainoita pavhu kana mumunda: simba rakaenzana neP = η × A × G, kugadzikana kwenguva yenzvimbo nguva dzezuva. Chii chinochinja ndechekuzvitarisa.

Kutonhora. Panels bvisa pamusoro 0.4% yezvavanoburitsa pazuva rimwe chete vakatonhora pamusoro 25 ° C (ona PV-thermal for the physics). Temperature yepaneli inogadziriswa nechiyero: mhepo inotonhora uye kutonhora kwezuva uye radiation. Vachinjiniya vanonyora izvi se T_module = T_air + G / U, uko U icho chiyero chekuora kwemhepo muwatts pameter square per kelvin. Pamusoro pemvura, mhepo inopisa uye ine huremu hwakawanda, uye mumifananidzo yakavhurika, kumashure kwepaneti pane nzvimbo yemvura. Field bvunzo yakawana yakanakisa kutenderera magadzirirwo akakwira U neanopfuura 22 W/m²K kana zvichienzaniswa nemasystem ezvinyorwa, akagadzira mapaneli akasimba kupfuura 3.2 °C muNetherlands uye 14.5 °C (kana achienzaniswa nerooftop system) muSingapore, uye akapa kusvika pa3% uye 6% yakawanda yemagetsi gore rega rega (Dörenkämper et al., 2021). Zvigadzirwa zvinopa mvura pasi pepaneti asi zvinowanawo mari shoma.

Evaporation. Paneles shade madziva uye kunonoka uswa pamusoro pake, saka zvishoma zvei zvinobuda. Pazvicherwa zvakaomarara, zvinotonhora izvi zvinogona kuitika sezvinoita nemagetsi: Jin navamwe vake vanofungidzira kuti 106 km³ pagore anochengetedzwa mu30% yemufananidzo wavo, wakagadzirwa kupfuura wakaitwa.

Power per hectare. Floating mazita anomira panzvimbo yakaderera uye akachengetwa zvakasimba, saka imwe hectare yemvura ine simba rakafanana neimwe hectare yenyika, inosvika 1 MW, uye inogadzira simba rakaenzana. Cirata muIndonesia inokwana 192 MWp panzvimbo ye200 hectares (Jakarta Post, 2023).

Hybrid nesimba remvura. Panzvimbo yemagetsi emvura, simba rezuva rinogona kushandisa iyo grid connection uye kubvumira damba kuti rigare richichengeta madziro pazuva rakajeka kuti riite zuva: nzvimbo yemvura inowanzova bhatiri rezuva.

Zvirambidzo

Theoretical. Kufamba hakuite kuti mhepo igadzire mvura: pane imwe nguva, pane rimwe zuva pane rimwe zuva pane imwe nguva. Global simba iri zhinji asi inorambidzwa nekuti sei yakawanda yeese reservoir anogona kuwanikwa pasina kukuvadza. Jin et al. dzidzo inobata yega yega reservoir pa30% uye 30 km².

Practical.

Uyu, mabwe uye mamiriro emvura. Makomo anofanirwa kuchengeta nzvimbo yepaneti kuburikidza nemhepo dzakaomarara uye nekukwira kwemvura iyo inogona kuchinja zviuru zvemamita. MuApril 2024, mvura yakanyanya nemhepo inosvika 50 km / h yakauraya 88 MW Indawadi plant, iyo iri chikamu cheOmkareshwar floating solar park muIndia (Times of India, 2024).
Cost. Floats, anchors and marine-grade connections cost more than ground frames; the US benchmark premium is about 25% (Ramasamy and Margolis, 2021).
Kuchengeteka. Zviri zvese zvinosvika nechikepe kana nenzira; zvipfuwo zvemasango, tsvina uye biofouling zvinoda kuchenesa; magetsi ekuchengetedza munzvimbo dzakatarisana nemvura anofanirwa kutariswa.
Ecology. Kubvisa mvura kunoderedza kusvibiswa kwezuva nemhepo. Kuongorora kwakanyatsojeka kwakawana kuti pane zvikonzero zvinokonzeresa kuderera kwemvura, oxygen, algae nemombe; vatungamiri vakaona kuti kuderera kwemvura inobuda muvhu senzira inonyanya kukosha uye shanduko yekemikari yemvura, kusanganisira deoxygenation, sechikonzero chikuru chekukuvadza. 15% chete yevanoshanda vakaongororwa vaida kuedza mhando yemvura (Exley et al., 2021).
Vamwe vashandisi. Masangano ekushandisa madziro, vafambi vechikepe, vanodyara masango uye nzvimbo dzemasango dzinogona kuchinja mamiriro ekunze.

NREL dzidzo yakawana mari yakanyanya kutaridzika kune mutengo wezvikepe, uswa uye snow zviwanikwa, uye module efficiencies.

Panogona kukunda, uye apo haigone

I can win:

nyika dzakakwirira nenzvimbo dzinotambura uko nyika isiri yakakwana: Singapore, Japan, South Korea, Netherlands, muchechi yeSouth uye Southeast Asia.
Hydropower reservoirs, uko kubatanidza kwe grid kunoonekwa uye madziro anogona kuchengetwa pashure apo zuva richibuda.
Kukanganisa kwezvivakwa, michina yemigwagwa uye zvipatara zveindasitiri izvo hazvina kushandiswa.
Hot, kutonhora nzvimbo apo madziro akaipa kune evaporation isiri nyore uye kupera kwekuwedzera kuri makuru.
Water utilities izvo zvinogona kudzora yavo yekupumpa uye kurapwa kubva kune yavo yekuchengetedza nzvimbo.

I can’t win:

Pane nyika iri cheap and plentiful. A solar farm on dry land will usually be cheaper and simpler.
Pamahombekombe ane mvura ine zvisikwa zvinorarama kana anoshandiswa pakuzorora, kunze kwekunge kuongororwa kwezvirwere kunoti chikafu chinodyiwa hachina kukuvadza.
Mumvura yakasviba, ine mhepo pasina zvisirizvo zvemari, uye kunze kwenyika pasina kukwira muhunyanzvi.
Seyakakura nyowani yemvura. Evaporation kuchengetedza ndezvechokwadi asi zvinogadzirwa; ivo vanobatsira, asi havaite mugwagwa mutsva.

Chii chinoratidza, chinofungidzirwa uye chinofungidzira

Proven: kuti kutenderera magetsi emazana megawatts anogona kuvakwa uye kushandiswa; kuti vanodhura zvakaderera kupfuura solar panyika; kuti kutonhora kwemvura inowedzera mamwe mapurosenti ekudyara mu open designs; kuti zvirwere zvinogona kukuvadza zvakanaka-kubva pasi magetsi.

Plausible: kuti kusanganisira yakaderera chikamu chemaresitorendi anogona kuwedzera kutonhora zvakanyanya, sezvakaratidzwa; kuti kubatanidzwa kwezuva nemvura kunowedzera kukosha nekushandiswa kweresitorendi senzvimbo yekuchengetera; kuti shading inogona kudzikisa kukuvadza kwealjage blooms mumamiriro ekunze.

Speculative: kuti global simba muzviuru zve terawatt-hours ndeyakanaka kana ichienzaniswa neecology, kushandiswa kwemvura uye grids; 25 gore renguva refu kurarama kwezvikepe zvinofamba nemadziro ezuva uye madziro; kuti open-sea floating solar inogona kuita kuti zvive zvakachipa.

Ongororo dzekutsvaga

Chii chinoitika kana mvura ichivhurwa ne10, 30 kana 50% pazvinoita oxygen, tembiricha, algae uye zvekudya muzvitsuwa zvakasiyana-siyana, zvichienzaniswa nemakore apfuura?
Chii chinonzi kutonhora kwemvura kunochengetedzwa mukuita, zvichimiririra nemari yemvura kupfuura mamodheru?
Ndezvipi zvinokonzera kuti zvikepe zvirambe zviri mumvura inopisa, uye kana zvichiitika, zvinoparadza sei microplastics kana zvinhu zvakaomarara mumafuta ekumwa?
