Indlela i-Highjoule Exazulula Ngayo Inkinga 'Yokungabi Nagridi, Akukho Signali' Kuyo Yonke I-Sub-Saharan Africa

Ngaphakathi kwesihloko sokufakwa kweziteshi zase-Afrika, umbuzo owodwa obuhlungu nongokoqobo uhlala uvela:

Ngaphandle kwegridi kagesi ezinzile, isiteshi sezokuxhumana singasebenza kanjani unomphela?

Ikakhulukazi eMauritania, eNiger, emaphakathi neKenya, nasezifundeni ezifanayo, izinkulungwane zezindawo zibhekene nezinselele ezifanayo:

• Akukho ukufinyelela kwegridi yokusetshenziswa
• Izindleko zokuthutha udizili eziphakeme kakhulu
• Izimo zezulu ezimbi kakhulu (ukushisa okushisayo + iziphepho zesihlabathi)
• Izinsizakusebenza ze-O&M (zokusebenza nokulungisa) ezintulekayo

Ngenxa yalesi simo, i-Solar + Storage + Diesel Hybrid System (i-integrated solar-storage-diesel) iye yaba yindlela evelele yokwakha amandla eziteshini ezingaphandle kwegridi e-Afrika. Lesi sihloko sibhekisela ezimweni zephrojekthi yangempela ye-Highjoule ukuze sichaze kahle ukuthi ukunikezwa kwamandla okuzinzile kutholakala kanjani ezindaweni ezikude kakhulu e-Afrika.

Isigaba 1: Inselele Yamandla Angempela Ebhekene Neziteshi Zezisekelo Zase-Afrika

Ukunika amandla isiteshi sesisekelo emazweni amaningi ase-Afrika akulula njengoku-'xhuma bese usebenza.' Kuyinselele yamandla ehlelekile engahlukaniswa ngezinkinga ezintathu ezixhumene:

1. Ukumbozwa Kwegridi Okwanele

• Izindawo ezinkulu azinawo nhlobo ugesi kazwelonke
• Lapho kukhona khona igridi, ayizinzile njalo

2. Ukuthembela ngokweqile kuDizili

• Uphethiloli kumele uthuthwe ngamaloli amabanga amade
• Izindleko zezokuthutha zodwa zingadlula izindleko zokukhiqizwa kukagesi
• Ukuntuleka kukaphethiloli = ukungasebenzi kwendawo

3. Ubunzima Obukhulu Be-O&M

• Izindawo zisakazeke ngokwendawo
• Imijikelezo yokuhlola ngesandla inde futhi iyabiza
• Izikhathi zokuphendula ngamaphutha zihamba kancane

Ngezansi: E-Afrika, ugesi othembekile uyinkinga enzima kakhulu ukuyixazulula kunokuthola ihadiwe yokuxhumana uqobo.

Isigaba 2: Isixazululo Esihamba Phambili — Izinhlelo Ezihlanganisiwe Zokugcina Ilanga-Udizili

Isixazululo esivuthiwe nesisetshenziswa kabanzi kakhulu seziteshi zase-Afrika namuhla ukwakheka kwe-hybrid okunemithombo emithathu:

I-PV yelanga + Isitoreji Samandla Sebhethri + Ijeneretha Kadizili

I-logic yokusebenza ilula kakhulu:

Isigaba 3: Ucwaningo Lwecala Le-Highjoule — Iziteshi Zezingcingo zaseMauritania

Okulandelayo yisibonelo sangempela sokusetshenziswa kwamasayithi ezokuxhumana angaphandle kwegridi:

3.1 Izinjongo Zomsebenzi

Imigomo eyinhloko yale phrojekthi yachazwa ngokucacile:

• Nikeza amandla athembekile kumasayithi angenawo ukufinyelela kwegridi yokusetshenziswa
• Thuthukisa ukuzinza kokusebenza kwesiteshi sesisekelo kanye nesikhathi sokusebenza
• Ukunciphisa kakhulu ukusetshenziswa kukaphethiloli kadizili kanye nezindleko zokuhamba ezihambisanayo
• Nika amandla ukusebenza okuzenzakalelayo okunganakwa isikhathi eside

Empeleni: gcina isiteshi sezokuxhumana siphila, sizinzile futhi singapheli, endaweni engenazo ingqalasizinda kagesi.

3.2 Umklamo Wokwakhiwa Kwesistimu (Ukuhlanganiswa Kwesitoreji Selanga Nedizili)

Le phrojekthi isebenzisa ukwakheka kwe-fusion okunemithombo emithathu yakudala:

Uhlelo lwe-PV yelanga (Umthombo Wamandla Oyinhloko)

• Ama-array amaningi e-PV module anezakhiwo zokufaka ezenziwe ngokwezifiso
• Ukunikezwa kwebhethri okubalulekile emini + ukushaja ibhethri ngasikhathi sinye

Uhlelo Lokugcina Amandla Ebhethri (I-Core Buffer)

• LFP Uhlelo lwebhethri (i-Lithium Iron Phosphate)
• Ukwakhiwa kwezakhiwo ze-telecom ezijwayelekile ezingama-48V
• Ikhono lokujikeleza okujulile elandisiwe ngomklamo othembekile kakhulu

Imisebenzi:

• Ukunikezwa kukagesi ebusuku
• Isinxephezelo sosuku olunamafu
• Ukunciphisa imvamisa yokuqalisa ijeneretha yedizili

Ijeneretha Kadizili (Umugqa Wokugcina Wokuvikela)

• Ijenereyitha yedizili ethule yangaphandle engu-16 kW / 20 kVA
• Ukulawula kokuqala/ukumisa okuzenzakalelayo okuhlakaniphile

Imisebenzi:

• Isipele sezikhathi ezinde zamafu
• Ukwengezwa komthwalo ophakeme
• Inethi yokuphepha ephelele yesistimu

3.3 Ukucushwa Kwemishini Eyinhloko (Ukuhlukaniswa Kwezinga Lobunjiniyela)

Isigaba 4: Indlela Uhlelo Olunikeza Ngayo Amandla Angaphazanyiswa

Impumelelo eyinhloko yale phrojekthi akuyona ukuqongelela imishini — kodwa yindlela yokuhambisa amandla:

Umphumela: Imithombo emithathu yamandla inikeza ukuphindaphinda okufanayo — ukufeza ukusebenza kwangempela kwesikhathi sokungasebenzi.

Isigaba 5: Inani Lephrojekthi

• Ivumela Ukumbozwa Okungaphandle Kwegridi — iletha ukuxhumana kwezokuxhumana ezindaweni ezazingafinyeleleki ngaphambili yigridi
• Kuthuthukisa Ukuqina — ukuphindaphinda kwemithombo eminingi kususa amaphuzu owodwa okwehluleka
• Kunciphisa Ukuthembela Kudizili — kunciphisa kakhulu imvamisa yokusetshenziswa kukaphethiloli kanye nezindleko zezokuthutha eziphelele
• I-Lowers O&M Burden — ukuqapha kude kuhlanganiswe nokulawula okuzenzakalelayo kuthatha indawo yokungenelela okubizayo ngesandla

Isigaba 6: Kungani Lesi Sixazululo Sifanelana Kahle Ne-Afrika

Izinhlelo zamandla zesiteshi samandla sase-Afrika zabelana ngezici ezintathu ezichazayo:

• Kuhlakazeke ngokwendawo
• Akusebenzi kugridi ngokuzenzakalelayo
• Kunzima ukuyinakekela ngesandla

Uhlelo lwe-hybrid lwesitoreji selanga nodizili luhambisana ngqo nalezi zidingo ezilandelayo:

• Isebenza ngokugcwele ngokuzimela ngaphandle kwengqalasizinda yangaphandle
• Iphathwa kude ngokuvakasha okuncane endaweni
• Ishintsha phakathi kwemithombo yamandla ngokuzenzakalelayo ngaphandle kokungenela komuntu

Isigaba 7: I-Afrika Iyashintsha Isuka 'Enkathini Kadizili' Iya 'Enkathini Yokugcina Ilanga'

Ubufakazi obuvela ensimini bukhombisa izinguquko ezintathu ezicacile ezenzekayo emkhakheni wamandla ezokuxhumana e-Afrika:

I-trajectory icacile: uhlelo oluhlanganisiwe lokugcina amandla elanga kanye nodizili luya ngokuya luba yindinganiso yangempela yamandla eziteshini zase-Afrika.

Isigaba 8: Isiphetho

Iphrojekthi yaseMauritania iqinisekisa isiphetho esibucayi:

Ezindaweni ezikude zase-Afrika, akukho mthombo wamandla owodwa ongasekela isiteshi sezokuxhumana isikhathi eside. Uhlelo lwe-Solar + Storage + Diesel hybrid luyisisombululo esithembeke kakhulu esitholakalayo namuhla.

Umbuzo oyinhloko weziteshi zase-Afrika awusekho 'Ingabe ikhona igridi?' kodwa kunalokho 'Ingabe ikhona uhlelo lwamandla oluhlanganisiwe lokugcina amandla elanga kanye nodizili?'

Mayelana ne-Highjoule Group

I-Highjoule Group igxile ezixazululweni zokugcina amandla ezihlanganisiwe zezinhlelo zokusebenza ezingaphandle kwegridi kanye negridi ebuthakathaka. Iphothifoliyo yethu yomkhiqizo ihlanganisa ukugcina amandla ekhaya, ukugcina amandla kwezentengiselwano kanye nezimboni, kanye nezinhlelo ezihlanganisiwe zokushaja isitoreji selanga. Izinzuzo zobuchwepheshe eziyinhloko zifaka phakathi ukubikezela amandla asebenzisa i-AI, ukuphathwa kwezindawo eziningi, kanye ne-O&M ekude. Izinhlelo zethu zisakazwa ngenkuthalo kulo lonke elase-Afrika, eNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi, nakwezinye izifunda - kusiza abaqhubi bezokuxhumana namabhizinisi ukuthi bathole ukunikezwa kwamandla okuthembekile, okuzimela, nokuhlakaniphile ezindaweni eziyinselele kakhulu emhlabeni.
