Iingcali zehlabathi jikelele kumandla elanga zikhuthaza kakhulu ukuzibophelela ekukhuleni okuqhubekayo kwe-photovoltaic (PV) yokuvelisa kunye nokuthunyelwa kwamandla eplanethi, ephikisana ukuba i-lowballing projections yokukhula kwe-PV ngelixa ilinde imvumelwano kwezinye iindlela zamandla okanye ukuvela komzuzu wokugqibela wezobuchwepheshe. imimangaliso "ayiseyiyo inketho."
Imvumelwano efikelelwe ngabathathi-nxaxheba kwi-3rdIworkshop yeTerawatt kulo nyaka uphelileyo ilandela ingqikelelo eyandayo evela kumaqela amaninzi kwihlabathi liphela malunga nesidingo sePV enkulu yokuqhuba umbane kunye nokunciphisa igesi eluhlaza.Ukwamkelwa okwandayo kobuchwephesha bePV kuye kwabangela ukuba iingcali zicebise ukuba malunga ne-75 terawatts okanye ngaphezulu kwePV esasazwe kwihlabathi jikelele iya kufuneka ngo-2050 ukuhlangabezana neenjongo ze-decarbonization.
Iworkshop, ekhokelwa ngabameli beNational Renewable Energy Laboratory (NREL), iFraunhofer Institute for Solar Energy eJamani, kunye neNational Institute of Advanced Industrial Science and Technology eJapan, baqokelela iinkokeli ezivela kwihlabathi jikelele kwi-PV, ukuhlanganiswa kwegridi, uhlalutyo, kunye nokugcinwa kwamandla, kumaziko ophando, i-academia, kunye neshishini.Intlanganiso yokuqala, ngo-2016, yajongana nocelomngeni lokufikelela ubuncinane kwii-terawatts ezi-3 ngo-2030.
Intlanganiso ka-2018 ishukumise ithagethi ngakumbi, malunga ne-10 TW ngo-2030, kwaye iphindwe kathathu loo mali ngo-2050. Abathathi-nxaxheba kuloo workshop baphinde baqikelele ngempumelelo ukuveliswa kombane kwihlabathi ukusuka kwi-PV kuya kufikelela kwi-1 TW kwiminyaka emihlanu ezayo.Lo mda ugqitywe kunyaka ophelileyo.
"Senze inkqubela phambili enkulu, kodwa iinjongo ziya kufuna ukuqhubeka nomsebenzi kunye nokukhawuleza," kusho uNancy Haegel, umlawuli weZiko leSizwe le-Photovoltaics kwi-NREL.U-Haegel ngumbhali okhokelayo wenqaku elitsha kwijenaliInzululwazi, "I-Photovoltaics kwi-Multi-Terawatt Scale: Ukulinda ayisiyiyo iKhetho."I-coauthors imele amaziko angama-41 avela kumazwe ali-15.
“Ixesha libalulekile, ngoko ke kubalulekile ukuba sizibekele iinjongo ezinqwenelekayo nezinokufezekiswa ezinempembelelo enkulu,” utshilo uMartin Keller, umlawuli we-NREL."Kuye kwaba nenkqubela phambili kwindawo ye-photovoltaic yamandla elanga, kwaye ndiyazi ukuba sinokufezekisa ngakumbi njengoko siqhubeka senza izinto ezintsha kunye nokwenza ngokukhawuleza."
Isehlo semitha yelanga inokubonelela ngokulula ngaphezu kwamandla aneleyo ukuhlangabezana neemfuno zamandla oMhlaba, kodwa yipesenti encinci kuphela esetyenziswayo.Isixa sombane esibonelelwa kwihlabathi jikelele yi-PV sinyuke kakhulu ukusuka kwisixa esingakhathaliyo ngo-2010 ukuya kwi-4-5% ngo-2022.
Ingxelo evela kwindibano yocweyo yaphawula ukuba "ifestile iya ivala kakhulu ukuthatha inyathelo lokunciphisa ukukhutshwa kwegesi eluhlaza ngelixa ihlangabezana neemfuno zamandla ehlabathi kwixesha elizayo."I-PV igqame njengenye yeendlela ezimbalwa ezinokuthi zisetyenziswe ngokukhawuleza ukutshintsha amafutha efosili."Umngcipheko omkhulu kule minyaka ilishumi izayo iya kuba kukwenza uqikelelo olulambathayo okanye iimpazamo ekulinganiseni ukukhula okufunekayo kwishishini le-PV, kwaye emva koko siqonde kade kakhulu ukuba besingalunganga kwicala elisezantsi kwaye kufuneka sinyuse imveliso kunye nokusasazwa ngokungenanyani okanye. amanqanaba angazinzanga.”
Ukufikelela kwithagethi ye-75-terawatt, ababhali baxela kwangaphambili, baya kubeka iimfuno ezibalulekileyo kubo bobabini abavelisi be-PV kunye noluntu lwesayensi.Umzekelo:
- Abenzi be-silicon solar panels kufuneka banciphise ubungakanani besilivere esetyenziswayo ukwenzela ukuba itekhnoloji ikwazi ukuzinza kwi-multi-terawatt scale.
- Ishishini le-PV kufuneka liqhubeke likhula ngesantya esimalunga nama-25% ngonyaka kule minyaka ibalulekileyo izayo.
- Ishishini kufuneka liqhubeke nokwenza izinto ezintsha ukuphucula ukugcinwa kwezinto kunye nokunciphisa indawo yalo yokusingqongileyo.
Abathathi-nxaxheba kwiindibano zocweyo baphinde bathi itekhnoloji yelanga kufuneka yenziwe ngokutsha ukulungiselela i-ecodesign kunye nesetyhula, nangona imathiriyeli yokurisayikilisha ayisosisombululo esinoqoqosho okwangoku kwiimfuno zemathiriyeli ezinikwe ukufakelwa okuphantsi kakhulu ukuza kuthi ga ngoku xa kuthelekiswa neemfuno zamashumi amabini eminyaka azayo.
Njengoko ingxelo iphawulile, ekujoliswe kuko kwe-75 terawatts ye-PV efakiweyo “yombini ingumngeni omkhulu kunye nendlela ekhoyo eya phambili.Imbali yakutshanje kunye nendlela esiphila ngayo ibonisa ukuba inokufezwa.”
