Iibhetri zomthi kunye nobushushu

Kwiintsuku ezishushu nezipholileyo, amacebo aninzi aseYuropu aneebhetri ezininzi kunazo zonke ezinokuzisebenzisa, kwaye ixabiso lihla likhulu kunesiphelo okanye nangaphantsi kwayo. Iiyure ezimbalwa kamva i-grid efanayo ihlawulisa inkxaso. Ibhetri yobushushu yindlela elula yokutsala iiyure ezibizayo: i-heater ye-electric ifudumeza umgubo omkhulu we-sand, iithayile ezitywiniweyo okanye ibhloko ukuya kumawaka eeqondo, ukhuselo oluqinileyo lugcina ubushushu ngaphakathi, kwaye ifan okanye isitshintshi sobushushu siyisusa xa ifuneka, iintsuku okanye iiveki emva koko.

About half of the world’s final energy use is heat, not electricity (IEA, Renewables 2019). Ininzi yayo ivela kumlilo wegesi, imveliso yeoli, intsimbi okanye umthi. Oku kwenza ukuba kube yimpumelelo enkulu, kwaye yile nto le phepha lithatha ingqalelo eqinileyo kwizinto ezibangelwa ubushushu kunye nezo zingabakho. Uhlobo olufutshane: igcinwe njengefuthe kwaye isetyenziswe njengefuthe, umbane ubuyela kwi-85 ukuya kwi-95%; ubuyiselwa kwakhona ube ngumbane, ubuyela kwi-30 ukuya kwi-41% ngokufanelekileyo. Le nto enye igqiba ukuba yeyiphi indawo ephumelelayo kwitekhnoloji.

Yintoni

Ibhetri yobushushu, ebizwa ngokuba yibhetri yeqondo lokushisa okanye ukugcina amandla obushushu asebenza ngeemoto, igcina umbane njengobushushu kwizinto eziqinileyo ezibiza kakhulu. Inkampani yaseFinland yePolar Night Energy isebenzisa isilivo sentsimbi esigcwele umthi wesakhiwo okanye i-soapstone eqhutywe kwaye idibanisa kwinethiwekhi yombane. IRondo Energy eCalifornia ifudumeza ibhloko ezimelana nomlilo ukuya ngaphezulu kwe-1,000 °C ukwenza umphunga weefektri. I-Antora Energy ifudumeza iibloki zecarbon de zikhanya kwaye zingabuyisela ubushushu okanye, ngeepaneli ezikhethekileyo ezinjengeeseli zokukhanya kwelanga, umbane. ISiemens Gamesa yaqhuba inkqubo ehamba phambili eHamburg eyagcina ubushushu kwilitye le volcanic kwi750 °C kwaye yajika kwakhona ibe yi-electricity ngemoto yomoya.

Ezi zonke ziyimbono enye kunye neqondo lobushushu elihlukileyo nabathengi abahlukeneyo. Imibuzo ebalulekileyo kuphela kukuba: ishushu kangakanani, ixesha elide kangakanani, ibiza malini kwaye isetyenziswa njani ubushushu.

Indlela esebenza ngayo

Ukutshaja. Umbane uhamba ngezixhobo zokufudumeza ezimelana nobushushu, inkqubo efanayo nekhetile okanye isitya sokutya esishushu. Olu guqulelo luyinxalenye ye100% esebenzayo: iyure nganye yekilowatt yombane ivela kwiyure nganye yekilowatt yokufudumeza. Iindawo zokufudumeza iPolar Night zishushulisa umoya ngee-resistors kwaye ziwuphuze ngemibhobho efakwe kumthi; ii-heater zeRondo zijikeleza ngokuthe ngqo kwi-brick.

Ukugcinwa. Inani le-energy egcinwe kwizinto eziqinileyo yi E = m × c × ΔT: isisindo sayo, amaxesha obushushu bayo obuthile, amaxesha okujikeleza kweqondo lobushushu. Umkhenkce ococekileyo kunye nezinto ezininzi zesikwere zinomphezulu wobushushu c malunga ne-0.8 ukuya kwi-1.0 kJ nge kilogram nganye ngeqondo. Itoni enye yomkhenkce eshushu ukusuka kwi-150 °C ukuya kwi-400 °C (ujikelezo lweeqondo ezili-250) ngoko igcina 1,000 kg × 0.8 kJ/kg·K × 250 K = 200 MJ, okanye malunga 56 kWh. Ivenkile yasePornainen isebenza kwi-100 MWh kwiitoni ezili-2,000, 50 kWh ngetoni, ehambelanayo. Amanzi ashushu kwitanki yobushushu bendawo, ejikeleza phakathi kwe-90 °C ne-50 °C, igcina malunga ne-47 kWh ngetoni; umkhenkce uphumelela kuba unokusebenza kakhulu ngaphandle kwenqanawa yokucinezela. Ukuthelekiswa, iiseli zebhetri ye-lithium-ion zigcina malunga ne150 ukuya kwi250 kWh yombane ngetoni.

Ukugcina ngaphakathi. Ubushushu buphuma ngaphandle ngendawo engaphandle, ngesantya se Q = U × A × ΔT, apho U ilinganisela ukuba ukhuselo luhle kangakanani na, A yindawo engaphandle kwaye ΔT imeko-bume yobushushu ohlukileyo kwindawo yangaphandle. Uxinzelelo olugcinwe lukhula ngobukhulu (i-cube yobungakanani) kunye nolahleko ngomgangatho (ukwesibini), ngoko ezikhulu zilahleka inxalenye encinci. Ubalo lwethu olunzima lwesilo lobungakanani bePornainen (15 m ububanzi kunye ne-13 m ubude, malunga ne-970 m² yomhlaba) ngentsimbi ekhuselayo evumela ukuba idlule kwi-0.1 W ngomqolo ngamnye wemitha nganye ngomgangatho kunye notshintsho lweqondo eli-300: malunga ne-29 kW, okanye i-0.7% yendawo yokugcinwa epheleleyo ngosuku. Ivenkile encinci ubungakanani begadi yendlu ilahleka amaxesha amaninzi loo nxalenye, leyo yiyo nto iibhetri zesikwere zikhiwa kumadolophu neefektri, hayi kwiindlu ezizimeleyo.

Ukukhupha. Ubushushu, umkhenkce uphefumla umoya ngesantya esiphezulu se-sand kunye nomtshintshi wobushushu odlula ubushushu kumanzi enethiwekhi. Akukho nto malunga nale inomdla. Umbane, ubushushu kufuneka buqhube i-injini, kwaye apha ifizikhi ibeka umda onzima. I-Carnot efficiency, engcono nayiphi na i-injini yobushushu ingayenza ngaphambili, yi η = 1 − T_cold / T_hot, ngeqondo lobushushu kwi-kelvin. Ubushushu kwi-400 °C (673 K) oburhoxisiwe kwi-30 °C (303 K) bunika 1 − 303/673 = 55%. Kwi-750 °C inqanaba liyi-70%. Real steam turbines, pumps and heat exchangers reach roughly half the Carnot figure, so a store returns something like 25 to 40% of the electricity it bought. Uyilo olupapashwe lwendawo yokugcinwa kwelitye eSorø, Denmark, lulindele ukuba 30 ukuya kwi-41% ibuyiselwe njengeebhetri okanye i-41 ukuya kwi-58% njengeqondo lobushushu (Wikipedia, Ukugcinwa kombane obandayo).

Ukuphela komsebenzi: ibhetri yobushushu yindlela elungileyo yokukhusela impahla xesha elifanelekileyo, kunye nendlela ebi yokuhambisa kusetyenziswa ukuze zisetyenziswe kamva, ngaphandle kokuba i-injini yobushushu ibonakale ingcono kakhulu okanye amandla okuhlawulisa afana nokufumaneka.

Iinjongo

• I-theoretical. Ubushushu obuthile kunye notshintsho lweqondo lobushushu lumisela amandla kwitoni nganye; iCarnot equation imisela ukuba ninzi kangakanani na elinokuthi liphinde libe negesi. Akukho yilo oluhle luyaphuma na.
• Iqondo lobushushu lihambelana nokusetyenziswa. Ukushisa kwendawo kufuneka 60 ukuya kwi-120 °C, iifashoni zephepha nezokutya zifuna umphunga osuka kwi-150 ukuya kwi-250 °C, iikhemikhali kunye nesinyithi zifuna i-400 ukuya kwi-1,500 °C. Iqondo lobushushu eliphezulu ligcina ngaphezulu kwitoni kodwa ifuna isinyithi, ibhloko eshushu nentsimbi engenasici ezibiza kakhulu kwaye zisebenzisa nzima.
• Umbane versus amandla. Ii-heater kunye neendawo zokutshintshiselana ngamandla (ecaleni lombane) zihlala zibiza kakhulu kunesinyithi (ecaleni lombane). Ivenkile ehlawuliswa kuphela kwiintsuku ezimbalwa ezibizayo ifuna izifudumezi ezinkulu ezihlala zikhululekile ixesha elide.
• Izijikelezo ngonyaka. I-euro nganye yezixhobo kufuneka ibuyiselwe emva ngobushushu obuyitshintshileyo. Ivenkile ejikeleza amaxesha angama-200 ngonyaka ikhupha iindleko zayo zincinci kakhulu kunenye ejikeleza amaxesha angama-20. IPolar Night isithi iindawo zayo zokugcinwa zisebenza kakuhle phakathi kweenkqubo ezili-20 nezo li-200 ngonyaka (Solarthermalworld, 2024).
• I-electricity ethe tyaba kufuneka ikhona. Imeko yeshishini ixhomekeke kwiintsuku ezininzi zexabiso eliphantsi. Iigridi ezinesixa esikhulu somoya nelanga, ezinjengeFinland, Denmark kunye neCalifornia, zizifumana; iigridi ezineempawu ezincinci ze-variable power azizifumananga.

Izilumkiso ezimbini malunga nale teyibhile. Ukuqala, iindidi ezininzi zivela kwiinkampani okanye kubathengi babo, hayi kwi-metric ekhululekileyo. Eyona nto ibalulekileyo, i-85% yeKankaanpää ishushu kwakhona ngeyunithi nganye yombane kwi; akukho mntu kule theyibhile upapashe unyaka wendlela ejikelezayo yombane olinganiselweyo kumandla ombane kwinqanaba lorhwebo.

Iilaboratoriya zophando ziphakamisa ubushushu. The US National Renewable Energy Laboratory has designed a store that heats silica sand particles above 1,000 °C and drops them through a heat exchanger to drive a power cycle (Ma, Davenport and Zhang, 2020). IMalta, ejikelezwe ngaphandle kwe-Alphabet’s X ngo-2018, ilandela “iCarnot battery” egcina ubushushu kwisitya esixutyiweyo kunye nobushushu kwi-cooled liquid ukunyusa uhambo olujikelezayo. Ezi ziyimfuneko, aziqinisekiswanga ngobungakanani.

Ixabiso

Iibhetri ezishushu azivelisi umbane, ngoko ke ixabiso labo elifanelekileyo alikho kwipaneli yelanga kodwa ubushushu obuzifaka endaweni. Ixabiso lethu elipheleleyo lombane omtsha endlwini lihlala liphezulu kwesophahla selanga malunga ne-$0.19 ngekwh nganye kwimodeli yethu evulekileyo ye Fan Wall model, ngaphakathi kwexesha leLazard ngoJuni 2026 lokurhweba ngesophahla selanga le-$0.09 to $0.20 ngekwh (Lazard LCOE+ 2026). Ubushushu, umncinane yibhoyile yegesi.

Ixabiso legesi yokufudumeza. Ukusebenzisa amanani ajikelezayo afana namanqanaba aseYuropu ngo-2025 no-2026 (igesi yorhwebo olukhulu kwi-€35 ngeMWh, ixabiso lekhabhoni ye-€70 ngetoni, ibhoyile esebenza kakuhle nge-90%), ubushushu begesi bubiza malunga ne-5 ukuya kwi-6 yeesenti zeeuro nge-kWh phambi kokuba ibhoyile ihlawule imali-mboleko yayo. Usapho olukwinqanaba lexabiso eliphezulu e-UK luhlawula iipesenti ezingama-7.97 ngekwh nganye yegesi ukusukela ngoOktobha 2026 (Ofgem), malunga neepesenti ezingama-8.9 ngekwh nganye yobushushu.

Iindleko zeqondo lobushushu eligcinwe. Iinxalenye ezimbini: umbane, ohlukaniswe ngokusebenza kakuhle, kunye nezixhobo, ezihlukaniswe ngokuninzi kobushushu obunika ubomi bayo. Umbane nge-€20 ngeMWh (oqhelekileyo kwiyure ezishushu zaseNordic) nge85% yokusebenza kakuhle ibiza malunga ne-2.4 yesenti nge-kWh yobushushu. Inxalenye yezixhobo ixhomekeke kwixabiso elifakwe nge-kWh nganye yokugcina amandla kunye nenani leenkqubo ezipheleleyo ngonyaka. Neither Polar Night nor its customers have published the price of Pornainen, so we show the range instead of inventing a number (20 years, 7% real discount rate, 90% of capacity used per cycle):

Ixabiso elifakwe kwi-kWh nganye	20 iziqendu ngonyaka	50 iziqendu ngonyaka	100 iziqendu ngonyaka	200 iziqendu ngonyaka
$10	$0.052	$0.021	$0.010	$0.005
$25	$0.13	$0.052	$0.026	$0.013
$50	$0.26	$0.10	$0.052	$0.026

Ixabiso lezixhobo nge-kWh nganye yobushushu obunikezelwa, phambi kombane. I-calculation yethu.

Against lithium-ion. Battery packs averaged $115 per kWh in 2024, a 20% fall in a year (BloombergNEF, 2024), and a complete grid battery costs more than its pack. Ibhetri ye-lithium-ion ibuyisela malunga neepesenti ezingama-85 ukuya kuma-90 zesibane sayo njengesibane. I-sand ngokwayo ayihlawulisi nto: kwizigidi zeedola ngetoni kunye ne-50 kWh ngetoni, iphakathi iyingaphantsi kweedola nge-kWh. I-silo, ukhuselo lwelanga, ii-heater kunye nee-exchangers zeqondo lobushushu yimali eyiyo. Ibhetri yobushushu ithetha into kuphela ukuba yonke imali yayo efakwe kwi-kWh iphantsi kakhulu kunelithiyum yebhetri, kuba into enika ezantsi kubushushu, hayi umbane.

apho ingaphumelela khona, nalapho ingaphumelelanga

Inokufumana:

• Ubushushu bendawo kwi-grids eshushu okanye enelanga. Imimandla yaseNordic neBaltic enemijelo yombane, iiyure ezininzi ezibizayo kunye nemithi okanye ibhoyile yegesi yokutshintsha Le yindawo apho yonke ibhetri yomthi yorhwebo iye yadlula.
