La Umbane waseDubai kunye noGunyaziwe waManzi (DEWA) ibingumbindi woqwalaselo lwehlabathi ngesibhengezo sayo samva nje samaxabiso ethenda eenkampani ezine ezikhuphisanayo ukuphuhlisa isigaba sesine se. Ipaki yelanga kaMohammed bin Rashid Al Maktoum, iprojekthi ephawula ngaphambili nasemva kwamandla ahlaziyekayo. Elona bhidi lisezantsi lingenisiweyo kule projekthi amandla elanga agxininisiweyo (CSP) yi-9,45 yeesenti zase-US nge-kWh nganye, elingana ne-8,5 yeesenti zee-euro, ibeka irekhodi elitsha lehlabathi.
Eli xabiso alixhomeki nje kuphela, kodwa likwamele ukuncitshiswa okuphantse kube ngama-40% ukusuka kwelona xabiso liphantsi lesizukulwana sangaphambili kwihlabathi jikelele. Ukongeza, ezinye izibonelelo ezimbini kwakhona amaxabiso abhalisiweyo ngezantsi Iisenti ezili-10 nge-kWh nganye, ebonisa ukukhuphisana okukhulayo kunye nokusebenza kwamandla okushisa elanga xa kuthelekiswa nezinye iinketho zobuchwepheshe. Olu phuhliso lubeka iDubai njengenye yemimandla ephambili kuphuhliso lwamandla elanga kunye neteknoloji yokugcina amandla.
Inqanaba lesine le isityalo esishushu selanga iya kubandakanya iplanti enobuchwephesha benqaba kunye nogcino lwamandla ukuya kuthi ga Iiyure ze12, nto leyo eya kuvumela ukuba i-complex iqhubeke nokubonelela ngombane nasebusuku. Esi sisiqalo nje seprojekthi enebhongo ngakumbi eya kuthi ekugqibeleni ibe ne-1.000 MW yamandla obushushu belanga. Le nkqubo ivelisa ngakumbi ngokwemiqathango amandla okugcina, kuba isebenzisa ityuwa etyhidiweyo ukugcina amandla e-thermal, eyenza ukuba ilawuleke imini nobusuku.
E-Dubai, isityalo selanga sase-Mohammed bin Rashid Al Maktoum siye sandiswa izihlandlo ezininzi ukususela ekudalweni kwayo ngo-2013, xa senza i-13 MW kuphela. Esi sigaba sokugqibela asiyonto ngaphandle kokwalula ukuya kwinjongo yokugqibela ye ukufikelela kwi-5.000 MW yomthamo ofakelweyo ngo-2030. Lo mzi-mveliso uza kubandakanya eyona nqaba iphakamileyo yelanga emhlabeni, enobude obuphezulu. 260 mitha, ukuphawula enye irekhodi yehlabathi e-Dubai ngokubhekiselele kumandla avuselelekayo.
Alithandabuzeki elokuba i-solar thermal iyakhula. Nangona kunjalo, imeko kwi España Yahlukile. Ngenxa yokusikwa okwenziwe kwi izityalo amandla elanga thermal, Iinkampani zaseSpain ziye zaxoshwa njengabakhuthazi bolu hlobo lweeprojekthi kwinqanaba lamazwe ngamazwe. Nangona kunjalo, IProtermosolar Uthemba ukuba iinkampani zaseSpain zinokuthatha inxaxheba njengeekontraki ezingaphantsi kule kunye nezinye iiprojekthi ezizayo. Kwinqanaba laseYurophu, uxinzelelo lwangoku oluvela kwi-EU ukunyusa isabelo samandla avuselelekayo, kunye neendleko eziphantsi, kunokuvuselela imarike eSpain kwiminyaka ezayo.
Enye yezona ndawo zinamandla zeteknoloji ye-thermal ye-solar kukuba, ngaphezu kweendleko zayo eziphantsi zangoku, inika ithuba lokudibanisa ukuveliswa kombane kunye ukugcinwa kwamandla, into ephambili yokuzinza kwegridi yombane. Ngokutsho kweengcali zoshishino, yi iteknoloji elawulekayo kuphela enokubonelela ngezi nzuzo, ngakumbi kumazwe anemitha yelanga eninzi. Lo mthamo wokugcina unokwenzeka ngenxa yokusetyenziswa kweetyuwa ezityhidiweyo, ezivumela ukuba isityalo sisebenze ngokuqhubekayo nangokuzinzileyo.
IDubai ayipheleli nje ekukhokheleni indlela ngesona sityalo sikhulu sobushushu belanga emhlabeni, kodwa yenze inkqubela phambili xa isiza ukugcinwa kwe-thermal. Isityalo sibeke enye irekhodi yehlabathi ngokufikelela 6.000 megawatt iiyure (MWh) umthamo wokugcina usebenzisa iityuwa ezinyibilikisiweyo, eziya kuyivumela ukuba inike amandla iiyure ezininzi emva kokutshona kwelanga. Lo mzi-mveliso uza kudibanisa ama-250 MW wamandla elanga e-photovoltaic, nto leyo eyenza ibe yindawo ehlaziyiweyo yomhlanganisela.
Ezi ntlobo zeeprojekthi zifuna utyalo-mali olukhulu. Isigaba sesine sepaki yelanga ye-Mohammed bin Rashid Al Maktoum e-Dubai ibona utyalo-mali olungaphezulu 3.200 million. Ngokutsho koqikelelo, iprojekthi iya kubonelela amandla acocekileyo nazinzileyo ukuya kumakhaya angama-320.000 kunye nokunciphisa ukukhutshwa kwekhabhoni nge-1,6 yezigidi zeetoni ngonyaka, okomeleza indawo yaseDubai njengenkokeli yehlabathi ekulweni nokutshintsha kwemozulu.
Ngokutsho kukamongameli weProtermosolar, uLuis Crespo, iindleko zangoku zokuvelisa umbane kunye nezityalo ezishushu zelanga ezineeyure ezintandathu zokugcina. bancinci kunezo zityalo ze-photovoltaic. Ngaphezu koko, iCrespo iqinisekisa ukuba amaxabiso e-solar thermal aya kuqhubeka nokuwa njengoko iteknoloji iguquka, eya kuvumela le teknoloji ukuba ikhuphisane ngakumbi kwimarike yamandla yehlabathi. Ukuthelekisa yangoku I-5 GW yomthamo wamandla obushushu belanga ifakwe kwihlabathi jikelele xa kuthelekiswa ne-500 GW yamandla omoya okanye i-300 GW ye-photovoltaics, amandla ombane obushushu belanga ukunciphisa iindleko zikhulu kakhulu.
Ngokuncitshiswa rhoqo kweendleko kunye nokukwazi ukuvelisa amandla ahanjiswayo imini nobusuku, i-thermal yelanga iyaqhubeka ibonakalisa iteknoloji ephambili kwixesha elizayo leenkqubo zamandla kumazwe anemitha yelanga eninzi.
