Enye yeengxaki ezinkulu ngamandla elanga kukuba iyahluka ngokungaguquguqukiyo kuxhomekeke kwimini kunye nexesha. Uninzi lweziqalo zisebenzela ukuphucula ukunikezelwa kwamandla emini-ukugcina amandla emini ukuze asetyenziswe ebusuku okanye ngexesha leeyure ezingasebenzi.
Kodwa bambalwa abantu abaye bajongana nengxaki yokugcinwa kwe-off-season yamandla elanga. Kuthekani ukuba amakhaya anokonga umlinganiselo omkhulu wamandla elanga avelisiweyo ebudeni beenyanga ezinelanga aze awasebenzisele ukufudumeza nombane ebusika?
Ukuza kuthi ga ngoku lo mbono awukafezeki. Iibhetri zibiza kakhulu kwaye zihlala zifutshane, zibiza kakhulu kwaye zingasebenzi kakuhle, ngoko ke i-hydrogen, engavelisi i-greenhouse gases xa itshiswa, yayingabandakanywa kwisisombululo.
Ngoku isiqalo saseNorway sithi sinokuzisa isisombululo esiqinileyo se-hydrogen kwintengiso kwiminyaka embalwa ezayo. INorway lilizwe elisenokufuna ukugcina ukukhanya kwelanga ebudeni beenyanga ezibandayo zasebusika.
I-Photoncycle yokuqalisa inesithuba kumgangatho ongaphantsi we-Oslo Science Park accelerator. Ijongeka ngakumbi njengelabhoratri kuneofisi: emgangathweni kuhleli isilinda sobhedu esilingana nesitulo, esongwe ngegwebu elishinyeneyo. Le yiteknoloji ye-Photoncycle yenguqu.
Inkampani inethemba lokufakela imodeli enkulu ye-cylindrical enokulinganisa malunga ne-cubic metres ezintathu emhlabeni kwiiyadi ezimbalwa ukusuka kwindlu. I-cylinder iqulethe isisombululo se-hydrogen esomeleleyo esinelungelo elilodwa lomenzi wesisombululo esinamandla ogcino afanelekileyo kuneebhetri okanye i-hydrogen engamanzi.
Iipaneli zelanga kuphahla lwezakhiwo ezikufutshane ziya kunika inkqubo amandla agcinwe kwiiyunithi. Amandla agqithisileyo aya kuthengiswa kwigridi.
Ukungabikho kokugcinwa kwamandla elanga avela ehlotyeni kubangela "ukungalingani okukhulu" phakathi kwamaxesha okuvelisa kunye nokusetyenziswa: "Olu lucelomngeni olukhulu kwindlela yokwenza iinkqubo zamandla avuselelekayo zisebenze ngokufanelekileyo," kusho uBjörn Brandtsaeg, umsunguli wePhotoncycle.
"I-50% eseleyo iba yinto engenamsebenzi ngenxa yokuba xa sele ivelisiwe, ngokuyimfuneko ilahlwa okanye inciphe. Ukuba unako ukugcina amandla angaphezulu kwaye uwakhulule ebusika okanye xa uneemfuno zamandla, ngoko unethuba lokwenyani lokwenza umehluko."
UBrandtsaeg ngusomashishini onamava kwiziseko zophuhliso. Iinkampani zakhe ezimbini zangaphambili zazinkulu: inkampani yeziseko zamandla eGeorgia kunye neQela laMandla acocekileyo, inkampani yaseNorway yamandla avuselelekayo. Ngokuthelekisa, iPhotoncycle inabasebenzi abalithoba kwaye ixhaswe ngemali kule minyaka mibini idlulileyo yimali kaBrandzaeg kunye nemali yeLabhu yokuQalisa.
Ingcamango yenkampani yavela ngelixa u-Branzaeg wayengumfundi otyeleleyo e-MIT, apho wayeyinxalenye yeqela elifunda ikamva lokugcina amandla kunye nendlela yokulinganisa igridi yamandla eyenziwe yi-100% yamandla avuselelweyo. Umrhwebi ongekho zobugcisa udibene kunye noososayensi ukufumana isisombululo esingatshayo esingalahleki amandla amaninzi ngexesha lenkqubo yokuguqula.
UBrandtsaeg uphakamise into efana netshokhwe: “Ngale nto ungagcina ubuninzi bamandla obuphindwe ngama-20 kunebhetri ye-lithium.”
"Sifakela i-molecule ye-hydrogen ibe yinto eqinile, ngokuyisiseko siyilungisa. Sisebenzisa i-reversible high heat fuel cell, ngoko sinceda ukuphuhlisa i-fuel cell enokuvelisa i-hydrogen kunye nombane kwiseli enye, "watsho.
Oku kuthetha ukuba i-hydrogen ayifuni ukuba ipholiswe, iyenza ukuba ingabikho ukutsha kwaye ixinene kuneebhetri ze-lithium-ion.
"Wonke umntu uyazi ukuba xa uhambisa i-hydrogen ngaphakathi nangaphandle kwe-fuel cell, kukho ilahleko. Kwinkqubo yethu, ilahleko ngokwenene kubushushu, "utshilo uBrandzaeg.
“Ungasebenzisa ubushushu obuchithekileyo ukunika amandla ngokufanelekileyo ikhaya—i-70 pesenti yeemfuno zamandla zekhaya kukufudumeza,” utshilo.
Inkqubo ibandakanya iiphaneli zelanga ezidibanisa ngokuthe ngqo kwiziseko ezikhoyo kwaye zinokuthi zithathe indawo yegesi yendalo ngamandla ahlaziyekayo kwinkqubo yokushisa kunye namandla adibeneyo. UBrandtsaeg uthe ukufakela kuya kuthatha malunga nosuku.
Omnye unokucinga ukuba inkampani yaseNorway iya kuvavanya imveliso eNorway kuqala. Nangona kunjalo, kuba iNorway inawona mandla aphantsi eYurophu, ayizukuba nefuthe elifanayo lokonga iindleko kubasebenzisi.
Endaweni yoko, uBrandsag wakhetha ummelwane waseDenmark, ilizwe elinamaxabiso aphakamileyo anamandla eYurophu, ukuba abe ngowokuqala ukusungula itekhnoloji.
"I-Denmark yimarike efanelekileyo yokuqaliswa, kunye nezindlu ezijikelezayo ze-400,000 ezitshiswa yigesi kunye neoli," watsho.
IDenmark iphinde yagqiba ekubeni ikhuphe ukushisa kwegesi ngo-2030, okuya kukhuthaza abantu ukuba bajonge imithombo emitsha yokushisa, kusho uBrandzaeg.
Abathengi baya kufumana umatshini wamandla odityanisiweyo ngokupheleleyo ngemodeli yobhaliso, ukuhlawula umrhumo omiselweyo wenyanga olingana neendleko zamandla ezingaphantsi kwe-€0.10 nge-kWh. Ngamandla avelisiweyo kwaye athengiswa kwi-intanethi, i-Photoncycle inesicwangciso sokwabelana ngenzuzo kunye nabathengi abafumana isiqingatha sengeniso evela kumandla athengisiweyo.
UBrandtsaeg uthe ngokufaka kunye nokudibanisa iiyunithi ezaneleyo, inokuba sisixhobo samandla esinokuthi siqalise ukurhweba ngamandla kwiimarike zamandla zaseYurophu.
"Oku kukuvumela ukuba ungathengisi amandla njengenkonzo kubathengi kuphela, kodwa ube ngumdlali onamandla kakhulu kwimarike yamandla."
Abaseki banethemba lokuphinda kathathu ubungakanani beqela kwaye bacwangcise ukuthengisa iiyunithi ze-10,000 eDenmark ngo-2025 kwaye bazifake ngo-2027.
UBrandtsaeg uthe umbono wokusebenzisa i-hydrogen eqinileyo yokugcina amandla wavela kwiminyaka eliqela eyadlulayo, kodwa iinkampani bezingekayisebenzisi kwiinjongo zasekhaya.
Iiseli zamafutha e-solid oxide esizisebenzisayo kungekudala ziza kurhweba.
Ngokuphunyezwa kweSicwangciso soBuchule seSolar se-EU, ukufakwa kweepaneli zelanga eluphahleni kulo mmandla kunokwenzeka ukuba kunyuke ngakumbi. Isicwangciso sokwenza kube sinyanzeliso kuzo zonke izakhiwo ezikhoyo zoluntu kunye nezorhwebo kwi-250 square metres ngo-2027, kunye nazo zonke izakhiwo ezitsha zokuhlala ngo-2029, ukunyusa okunamandla kwi-Photoncycle movement.
"Ingqiqo ka-Elon Musk kukuba ukuze ubethe iimoto zepetroli, kufuneka unikeze into ekhangayo ngakumbi kubantu njengenye indlela. Ndicinga ukuba yinto ebalulekileyo ekufuneka ucinge ngayo xa kuziwa kumandla avuselelekayo, "watsho.
