I-Vanadium Energy Storage - 1

Ukuthandwa kwemboni entsha yamandla kwenza i-lithium carbonate, impahla eluhlaza yamabhethri e-lithium, "amafutha amhlophe" Kubuchwepheshe bebhethri, omunye umzila wezobuchwepheshe "ugesi we-vanadium" nawo uqhakaza buthule.

Maphakathi noFebhuwari, "iphrojekthi kazwelonke ye-200MW / 800mwh isitoreji samandla sebhethri ye-Dalian liquid kanye nesiteshi sikagesi sokushefa okuphezulu" kumemezele ngokusemthethweni ukuthi ukwakhiwa kwephrojekthi enkulu sekuqediwe. Isiteshi sikagesi siwumklamo wokuqala kazwelonke omkhulu ongu-100MW wokugcinwa kwamandla kagesi kagesi eChina. Izoba futhi iphrojekthi enkulu kunazo zonke yokugcina amandla ebhethri ye-vanadium flow emhlabeni. Kulindeleke ukuthi kuphothule ukusebenza koxhumano lwegridi ngoJuni nonyaka.

Uyini umqondo wephrojekthi enkulukazi yomhlaba yokugcina amandla ebhethri? Isiteshi sikagesi sinamandla okugcina amandla angu-400mwh, okulingana no-400000 kwh. Ngokwesilinganiso sokusetshenziswa kwamandla kwanyanga zonke komndeni wama-degree angu-200, ingahlinzeka imindeni engaphezu kuka-2000 inyanga eyodwa. Njengesiteshi samandla sokushefa okuphezulu, kungadambisa ukucindezela kokushefa okuphezulu kwegridi yamandla wasendaweni futhi kwenze isidingo samandla ngesikhathi.

Ukugcinwa kwamandla kungumongo wenguquko entsha yemboni yamandla Embhalweni othi "ikhabhoni ephindwe kabili", ingxenye yokusetshenziswa kwamandla amalahle izokwehla, kodwa amandla amasha anjengamandla omoya namandla elanga abelokhu ebhekene nezici zokungaqhubeki, ukungazinzi kanye nokungalawuleki isikhathi eside. Ngakho-ke, indlela yokugcina kangcono le mithombo yamandla isibe isihluthulelo sokusebenzisa ugesi oluhlaza.

Ngokombono wesakhiwo sokugcina amandla, iShayina isagxile ekumpompeni nasekugcineni ugesi okwamanje - lapho ukusetshenziswa kwamandla kuphansi, amanzi ampontshelwa esuka endaweni engaphansi aye endaweni engaphezulu ngogesi, bese ededelwa amanzi ukuze aphehle ugesi endaweni ephakeme kakhulu. ukusetshenziswa kwamandla Ngo-2020, ingxenye yesitoreji esifuywayo e-China izofinyelela cishe ku-90%, kanti okwesibili isitoreji samandla e-electrochemical, okuhlanganisa ibhethri ye-lithium-ion, ibhethri le-lead-acid, ibhethri eligeleza uketshezi kanye nobunye ubuchwepheshe.
