Nogat. Ol bateri em i wanpela famili bilong ol LDES teknoloji. Mekanikel, thermal, gravitasenel, na kemikel stoa tu inap long givim longpela taim eneji.
"Olgeta samting i winim 10-pela aua em i gutpela moa"
Nogat. Tenpela aua em i wanpela gutpela DOE mak, i no wanpela veliu garanti. Ekstra taim i save kamapim veliu tasol taim grid o kastoma i nidim moa eneji we i stap.
"Teknoloji we i wok gut tru em i nambawan oltaim"
Nogat. Gutpela wok i save afektim kos bilong sasim, tasol LCOS i dipen tu long yutilisesen, saikel na kalenda laip, stoa-namel kos, O&M, ol senis, fainensing, na laip bilong projek.
"LDES i save givim bek-ap pawa otomatik"
Nogat. Bekap operesen i dipen long lektrikel akiteksa, ol kontrol, ailan, proteksen, stored-eneji risev, blak-stat kapabiliti we i gat nid, na lod we i mas stap strong.
"Lithium-Ion i no inap long kamap LDES"
Dispela i strong tumas. Lithium-ion i ken kamap long wok longpela taim. Askim em sapos dispela konfiguresen i stap yet long sait bilong teknikel, mani, na operesenel kompetitiv long dispela taim bilong wok.
FAQ
Q: Hamas aua em i longpela taim bilong putim pawa?
A: DOE i tok nau olsem LDES em i wanpela stoa we inap long givim pawa inap 10-pela aua o moa. Ol narapela fremwok i yusim ol narapela narapela mak, na ol plening stadi i ken luksave long inta-de, multi-de, na sisenal stoa.
Q: Wanem samting i narakain namel long sotpela taim na longpela taim bilong putim ol samting?
A: Bikpela samting i narapela em hamas taim ol i ken yusim eneji we ol i putim i stap inap long sapotim pawa bilong rausim pawa. Longpela taim i save senisim tu kos straksa bilong projek, strateji bilong ron long baisikol, ples, na bikpela samting bilong eneji resev na ol pawa-konvesen ikwipmen.
Q: Wanem ol teknoloji ol i yusim long LDES?
A: Ol bikpela famili em ol 'lithium-ion' na ol narapela bateri, ol 'flow' bateri, 'pumped-storage hydropower, compressed-air storage, thermal storage, gravity systems, hydrogen, na ol narapela kemikel eneji karia.
Q: LDES inap long putim pawa inap long sampela de?
A: Yes. Sampela 'mechanical', 'thermal', na 'chemical storage concepts' em ol i wokim bilong putim planti de o longpela taim moa. Sapos dispela inap i no gat bikpela pe bilong en, dispela i dipen long ples, samting bilong putim, ol samting bilong senisim, 'self-discharge, na hamas taim ol i yusim dispela pawa we ol i putim.
Q: Wanem Em i Gutpela Longpela-Eneji Stoa Teknoloji?
A: I no gat wanpela gutpela rot bilong olgeta manmeri. Stretpela teknoloji i dipen long taim bilong 'discharge', pawa, 'cycling frequency', ol hevi bilong sait, gutpela wok, sefti, 'maturity', 'bankability', na 'whole-life economics.
Q: Olsem wanem ol i mas skelim ol LDES teknoloji?
A: Yusim wanpela wankain diuti saikel na fainensel model. Skelim MWh, MW, taim, raun-trip efisiens, saikel na kalenda laip, self-discharge, bekim, mak, ples, sefti, maturity, riplesmen, O&M, na LCOS na noken skelim wanpela hetlain metric.
Pinis bilong tok: Stat wantaim Eneji Sevis Yu mas i gat
Longpela taim bilong putim eneji em i no wanpela resis bilong painim wanpela gutpela kemistri bilong bateri. Em i wanpela famili bilong ol teknoloji we i save stretim ol kain kain hevi long kain kain taim.
Wanpela projek we ol i wokim bilong muvim sola eneji long 12 klok i go long 12 klok nait em i narapela kain tru long wanpela projek we ol i wokim bilong abrusim sot bilong sola pawa long tripela de. Namba wan i ken laikim wanpela 'high-efficiency modular system we i save wok long olgeta de. Namba tu i ken putim moa veliu long liklik -kos eneji kapasiti, liklik 'self-discharge, bikpela 'reservoir', o longpela taim tru bilong putim ol samting.
Ol strongpela LDES projek i stat wantaim tripela namba:pawa yu nidim, pawa yu ken yusim, na taim yu nidim. Taim ol i makim pinis ol dispela samting, ol divelopa i ken skelim ol teknoloji long ol samting we i makim sapos ol i ken wokim, givim mani, ranim, na baim wanpela projek long laip bilong en.
