- Ucwaningo lwe-Berkeley Lab ekuxhumaneni kwegridi yase-US lubonisa ngaphezu kwesizukulwane esingu-2 TW nomthamo wokugcina emgqeni
- Iningi layo liholwa yilanga eline-947 GW kanye nesitoreji samandla esingeziwe esingu-670 GW phakathi kobunye ubuchwepheshe.
- Izifunda ezinkulu zokusebenza kwegridi njenge-CAISO ne-PJM azijabulisi izicelo ezintsha zokuxhuma igridi ngeso lokusalela emuva.
- Uhulumeni udinga ukwenza ngcono izinqubo zesikhungo ukuze asuse olayini futhi avimbele ukuhoxiswa kwemali
Izinkampani zegridi zase-US zigcwele amandla izicelo zokuxhumanisa zokudlulisa, ezibuswa amandla ahlanzekile, okuthi ekupheleni kuka-2022 zibe ngaphezu kuka-2 TW umthamo ophelele wokukhiqiza nokugcina, oholwa yi-947 GW solar PV, konke okudlula inani elidingekayo ukuze kufinyelele ku-90% kagesi wase-US kusuka ku-zero carbon resources ngo-2035, kusho uLawrence Berkeley National Laboratory (Berkeley Lab).
Ukulandela lokhu cishe 1 TW umthamo welanga emgqeni umoya wasogwini ongu-300 GW ohlanganisa umoya wasolwandle ongu-113 GW, kanye nesinye isitoreji samandla esingu-670 GW. Isitoreji selanga nebhethri sisodwa senza ngaphezu kuka-80% wamandla amasha angena emigqeni ngo-2022.
Phakathi kwamaphrojekthi we-hybrid, kukhona 475 GW we-solar hybrids, ikakhulukazi ilanga nebhethri, kanye ne-24 GW yezinhlobo ezixubile zomoya. I-Brekeley Lab ibala ngaphezu kuka-1.25 TW wamandla okukhiqiza i-carbon ayiziro efuna ukufinyelela kokudlulisela e-US. Ukwengeza, kukhona i-82 GW yemvelo kanye ne-1 GW yamalahle nayo emgqeni, ngokusho kocwaningo lweBerkeley Lab olunesihloko esithi. Kufakwe Emugqeni: Izici Zezindawo Zamandla Ezifuna Ukuxhumana Kokudluliswa Kusukela Ekupheleni kuka-2022.
Okungenani u-62% noma u-1.26 TW wesamba somthamo emigqeni unosuku oluhleliwe lokuphela kuka-2025, okuhlanganisa no-695 GW welanga, ukuze kuxhunywe ku-inthanethi kuyilapho u-13% noma u-257 GW usunesivumelwano sokuxhumana esikhishiwe.
Kodwa akugcini lapho. I I-Inflation Reduction Act (IRA) kungenzeka iqhubekisele phambili lokhu kukhula kwezicelo zokuxhumanisa maduze nje, ngokocwaningo.
Ukudlula kolayini abakhulu, I-CAISO ayizange yamukele noma yiziphi izicelo ezintsha zokuxhunywa kwegridi ngo-2022 ukuze ukwazi ukusula kuqala ukusilela emuva. Ngisho ne-PJM, okungesinye sezifunda ezinkulu zokusebenza zegridi yezwe e-US, imise kancane ukubuyekezwa kokuxhumeka okusha kuze kube ngu-2025..
Ngenkathi lokhu kukhomba Intshisekelo yabatshalizimali 'engakaze ibonwe' ekuthuthukisweni kwamandla ahlanzekile ezweni, ukubambezeleka okwandayo kanye namazinga aphezulu okuhoxiswa akhomba isithiyo esikhulu sabathuthukisi kulawa maphrojekthi, kuqokwe Umcwaningi Wenqubomgomo Yamandla e-Berkeley lab, uJoseph Rand.
Abahlaziyi bayakholelwa omningi walo mthamo ohlongozwayo ngeke wakhiwe ekugcineni ecaphuna idatha yeminyaka edlule. Bafuna kuphela ama-21% amaphrojekthi kanye no-14% wokuxhumeka kokufuna amandla kusukela ngo-2000 kuya ku-2017 akhiwe ekupheleni kuka-2022.
Izizathu abazicabangelayo zalokhu kuhlola yi isikhathi sokulinda sokuxhumana esikhulayo-phakathi kwesicelo sokuxhuma nokusebenza kwezohwebo-okukhuphuke kusuka ngaphansi kweminyaka emi-2 ngo-2000-2007 kuya cishe eminyakeni emi-4 kulabo abakhiwe ngo-2018-2022.
Ngesikhathi esifanayo, amaphrojekthi amaningi abonakala elindile kuze kube yizigaba zakamuva zenqubo yokuxhumana ukuze ahlehle. “Ukuhoxiswa kwesigaba sakamuva kungase kubize kakhulu konjiniyela futhi kungaphazamisa ukuqagela okwakhelwe ezifundweni zokuxhumanisa ezinye iphrojekthi, okungase kubambezele amanye amaphrojekthi,” kuphawula Umbhali-munye uRose Strauss.
Omunye umhlaziyi weBerkeley Lab uJulie Kemp uthe. “Ukusilela emuva okukhulu, ukukhuphuka kwezikhathi zokulinda, kanye namazinga aphezulu okuhoxa kolayini kuphakamisa izinselelo ezikhulayo zokuxhumanisa nokudluliswa kwempahla futhi kugqamise isidingo sokuthuthukisa izinqubo zesikhungo. "
Ucwaningo luyatholakala ukuze ludawunilode mahhala e-Berkeley Lab's iwebhusayithi.
Ocwaningweni lwangaphambilini ngale ndaba, iBerkeley Lab ithe amandla elanga angama-462 GW alinde ukuxhunywa kwegridi e-US ekupheleni kuka-2020.
