Nyob rau hauv xyoo tas los no, lub ntiaj teb no renewable zog tau tsim sai heev, tshwj xeeb tshaj yog photovoltaic fais fab tiam technology tau ua tsis tu ncua breakthroughs. Nyob rau hauv 2024, lub ntiaj teb loj tshaj plaws qhib offshore photovoltaic project tau ntse txuas rau daim phiaj nyob rau hauv Shandong, Tuam Tshoj, uas ib zaug dua attracted kev lag luam cov xim rau yav tom ntej ntawm offshore photovoltaics. Qhov project no tsis tsuas yog cim qhov kev loj hlob ntawm offshore photovoltaic thev naus laus zis, tab sis kuj muab cov kev taw qhia tshiab rau kev txhim kho lub zog tauj dua tshiab yav tom ntej. Yog li, yog vim li cas offshore photovoltaic thiaj li nrov? Txoj kev txhim kho yav tom ntej yog dab tsi?
1. Qhov zoo ntawm offshore photovoltaics: Vim li cas thiaj tsim nyog tsim?
Offshore photovoltaics (Offshore Floating PV) yog hais txog kev teeb tsa ntawm photovoltaic modules ntawm lub hiav txwv nto rau lub zog tsim. Piv nrog rau thaj av photovoltaics, nws muaj ntau yam zoo:
1. Kev txuag av
Cov chaw siv hluav taws xob photovoltaic nyob hauv av muaj ntau qhov chaw, thaum lub hnub qub photovoltaics siv dej hiav txwv, uas yuav pab daws cov teeb meem ntawm av, tshwj xeeb tshaj yog nyob rau thaj chaw muaj neeg coob lossis thaj chaw uas tsis tshua muaj av.
2. Kev tsim hluav taws xob ntau dua
Vim yog qhov kub thiab txias ntawm hiav txwv, qhov txias txias ntawm lub cev dej ua rau qhov kub ntawm photovoltaic modules qis dua, yog li txhim kho lub zog tsim hluav taws xob.
Cov kev tshawb fawb tau pom tias lub zog tsim hluav taws xob ntawm offshore photovoltaics tuaj yeem yog 5% ~ 10% siab dua li cov av photovoltaics.
3. Kev siv hluav taws xob txuas ntxiv
Offshore photovoltaics tuaj yeem ua ke nrog offshore cua zog los tsim "cua-hnub ci ntxiv" lub zog los txhim kho kev ruaj ntseg ntawm lub zog.
Nws tseem tuaj yeem ua ke nrog kev lag luam xws li marine ranching thiab seawater desalination kom ua tiav kev sib koom ua ke ntawm ntau txoj kev loj hlob.
4. Txo cov plua plav thaiv thiab txhim kho kev huv ntawm photovoltaic panels
Cov av photovoltaics tau yooj yim cuam tshuam los ntawm cov xuab zeb thiab av nkos, ua rau cov pa phem ntawm cov photovoltaic modules, thaum offshore photovoltaics tsis tshua muaj kev cuam tshuam los ntawm qhov no thiab muaj cov nqi kho mob qis dua.
2. Lub ntiaj teb loj tshaj plaws offshore photovoltaic project: Shandong txoj haujlwm ua qauv qhia
Kev vam meej kab sib txuas ntawm lub ntiaj teb loj tshaj plaws qhib offshore photovoltaic project nyob rau hauv Dongying, Shandong, cim ib theem tshiab ntawm offshore photovoltaics rau loj-scale thiab kev lag luam kev loj hlob. Cov yam ntxwv ntawm qhov project muaj xws li:
1. Lub peev xwm loj: Gigawatt-theem offshore photovoltaic fais fab chaw nres tsheb, nrog rau tag nrho cov peev txheej ntawm 1GW, yog lub ntiaj teb thawj qhov project mus txog qib no.
2. Kev ncua deb ntawm ntug dej hiav txwv: qhov project yog nyob rau hauv lub hiav txwv cheeb tsam 8 kilometers offshore, adapting mus rau complex marine ib puag ncig, ua pov thawj cov technical feasibility ntawm offshore photovoltaics.
3. Kev siv thev naus laus zis siab heev: Kev siv cov khoom siv tiv thaiv corrosion, kev ua haujlwm ntse thiab kev saib xyuas thiab cov hlua khi ntab tau txhim kho kev ntseeg tau thiab ua haujlwm ntev ntawm qhov project.
Txoj haujlwm no tsis yog tsuas yog lub sijhawm tseem ceeb hauv Tuam Tshoj txoj kev hloov pauv hluav taws xob, tab sis kuj muab kev paub rau lwm lub tebchaws los kawm thiab txhawb kev txhim kho thoob ntiaj teb offshore photovoltaics.
III. Cov xwm txheej tam sim no thiab yav tom ntej tiam sis ntawm lub ntiaj teb offshore photovoltaics
1. Lub teb chaws tseem ceeb uas tam sim no siv offshore photovoltaics
Tam sim no, ntxiv rau Tuam Tshoj, cov teb chaws xws li Netherlands, Nyiv, thiab Singapore kuj tseem siv zog ua haujlwm offshore photovoltaics.
Netherlands: Thaum ntxov li 2019, qhov project "North Sea Solar" tau tsim los tshawb nrhiav qhov ua tau ntawm cov hluav taws xob hluav taws xob sab hnub poob hauv Hiav Txwv North.
Nyiv: txwv los ntawm thaj av, nws tau siv zog tsim cov tshuab hluav taws xob photovoltaic nyob rau hauv xyoo tas los no thiab tau tsim ntau lub chaw nres tsheb photovoltaic offshore.
Singapore: Lub ntiaj teb loj tshaj plaws floating offshore photovoltaic project (60MW) tau tsim thiab tab tom txuas ntxiv los txhawb ntau daim ntawv thov offshore photovoltaic.
2. Yav tom ntej tiam sis nyob rau hauv txoj kev loj hlob ntawm offshore photovoltaics
(1) Kev txhim kho kev sib koom ua ke nrog lub zog cua sab nraud
Nyob rau hauv lub neej yav tom ntej, offshore photovoltaics thiab offshore cua fais fab yuav maj mam tsim ib tug "cua-solar complementary" qauv, siv tib lub hiav txwv cheeb tsam rau kev loj hlob ntawm lub zog. Qhov no tuaj yeem tsis tsuas yog txo cov nqi tsim kho, tab sis kuj txhim kho kev siv hluav taws xob.
(2) Kev siv thev naus laus zis thiab kev txo nqi
Tam sim no, offshore photovoltaics tseem ntsib cov teeb meem xws li ntsev tsuag corrosion, cua thiab nthwv dej cuam tshuam, thiab kev saib xyuas nyuaj. Txawm li cas los xij, nrog kev nce qib ntawm cov thev naus laus zis xws li corrosion-resistant photovoltaic Cheebtsam, kev ua haujlwm ntse thiab kev saib xyuas, thiab AI optimization tswj, kev tsim kho thiab tu cov nqi ntawm offshore photovoltaics yuav maj mam txo rau yav tom ntej.
(3) Txoj cai thiab kev nqis peev pab txhawb nqa
Tsoom fwv ntawm ntau lub teb chaws tab tom nce lawv txoj cai txhawb rau offshore photovoltaics, piv txwv li:
Tuam Tshoj: "14th Tsib Xyoo Plan" kom meej meej txhawb kev txhim kho ntawm ntug dej hiav txwv tshiab lub zog thiab txhawb kev sib koom ua ke ntawm kev tsim kho ntawm ntug dej hiav txwv photovoltaics thiab offshore cua zog.
EU: Pom zoo "European Green Deal" thiab npaj yuav tsim kom muaj kev lag luam loj nyob rau sab hnub poob rov qab siv zog los ntawm 2050, ntawm cov photovoltaics yuav suav rau qhov tseem ceeb.
IV. Kev sib tw thiab kev daws cov tswv yim ntawm offshore photovoltaics
Txawm hais tias offshore photovoltaics muaj kev cia siab dav, lawv tseem ntsib qee qhov teeb meem, xws li:
1. Kev nyuaj siab
Cua thiab yoj resistant tsim: photovoltaic Cheebtsam thiab brackets yuav tsum tau tiv taus hnyav marine ib puag ncig (xws li typhoons thiab siab nthwv dej).
Anti-corrosion cov ntaub ntawv: Seawater yog heev corrosive, thiab photovoltaic modules, brackets, connectors, thiab lwm yam yuav tsum tau siv ntsev tsuag corrosion resistant cov ntaub ntawv.
