1. Kev siv zog ntawm cov hlau ntau lawm:
Kev lag luam steel yog ib qho ntawm cov khoom siv hluav taws xob ntau tshaj plaws hauv ntiaj teb, suav txog kwv yees li 7-9% ntawm kev siv hluav taws xob thoob ntiaj teb. Hais txog kev siv hluav taws xob, nws tau kwv yees tias hluav taws xob arc rauv (EAFs) (uas tau nrov zuj zus los ua cov hlau) siv li ntawm 400-600 kWh ntawm hluav taws xob ib tuj ntawm cov hlau tsim.

● Steel zus tau tej cov txheej txheem kub kub, xws li blast furnaces, uas yuav tsum tau ib tug loj npaum li cas ntawm lub zog, feem ntau nyob rau hauv daim ntawv ntawm cov pa roj thiab thee rau cua sov thiab melting.

2. Energy Mix hauv Steel Production:
● Lub zog sib xyaw rau steel ntau lawm txawv raws thaj tsam, nyob ntawm seb muaj cov khoom siv hluav taws xob. Hauv ntau thaj chaw, steel mills cia siab rau cov thee thiab cov nkev roj, uas tuaj yeem ua rau cov nqi hluav taws xob tsis zoo.

● Nyob hauv cov teb chaws tsim, muaj kev hloov mus rau hluav taws xob arc rauv (EAFs) uas siv hluav taws xob, tshwj xeeb tshaj yog hluav taws xob tauj dua tshiab, uas tuaj yeem ua rau muaj hluav taws xob ntau dua thiab qis dua.

● Txawm li cas los xij, cov nroj tsuag loj loj uas siv lub tshuab hluav taws xob tawg (BFs) tseem muaj nyob hauv ntau lub tebchaws tab tom txhim kho thiab vam khom rau fossil fuels.

3. Kev xav tau siab zog thiab Peak Loads:
● Kev tsim cov hlau feem ntau cuam tshuam txog qhov xav tau hluav taws xob siab tshaj plaws, tshwj xeeb tshaj yog thaum lub cub tawg loj lossis lwm lub tshuab hluav taws xob siab siv. Qhov no ua rau muaj kev sib tw hauv kev tswj cov nqi thiab zam kev cuam tshuam hauv kev tsim khoom thaum lub zog xav tau nce ntxiv.

● Qhov xav tau lub zog tas li thaum lub sijhawm ua haujlwm ntev thiab cov txheej txheem siv siab (xws li melting thiab forging) ua rau lub zog cia tseem ceeb rau kev ua haujlwm zoo, txo qis kev cia siab ntawm cov hluav taws xob kim kim, thiab xyuas kom tsis muaj kev cuam tshuam.

4. Kev cuam tshuam ib puag ncig:
● Steel ntau lawm yog lub luag hauj lwm rau kwv yees li 7% ntawm lub ntiaj teb no CO2 emissions vim nws tso siab rau carbon-intensive roj qhov chaw. Kev lag luam yog nyob rau hauv kev nce siab kom txo qis emissions thiab txhim kho sustainability.

● Renewable zog kev koom ua ke nyob rau hauv steel mills tab tom tshawb nrhiav, tab sis tsis muaj cov kev daws teeb meem ruaj khov, cov chaw sib cuam tshuam xws li cua thiab hnub ci tsis tuaj yeem siv tag nrho thaum lub sijhawm tsis nco qab. BESS tuaj yeem ua lub luag haujlwm tseem ceeb los ntawm kev khaws cia lub zog tauj dua tshiab thaum muaj thiab muab nws thaum xav tau ntau lawm.

Zog Cia raws li kev daws teeb meem? Nws Ua Haujlwm Li Cas?

1. Smoothing fais fab mov txheej txheem
● Battery Energy Storage Systems (BESS) tuaj yeem daws cov teeb meem ntawm kev lag luam hlau los ntawm kev ua kom cov khoom siv hluav taws xob ua kom zoo thiab muab cov khoom tsis zoo rau lub sijhawm xav tau siab tshaj plaws, txo qis kev cia siab rau cov khoom siv sab nraud.

● BESS kuj tseem ua rau lub ncov shaving, qhov chaw khaws cia lub zog siv thaum lub sij hawm ncov kom txo tau cov nqi hluav taws xob thiab zam kom tsis txhob muaj tus nqi siab, tshwj xeeb tshaj yog thaum cov hlau ntau lawm.

● Ib tsob ntoo zoo li qub tuaj yeem txuag tau cov nqi hluav taws xob tseem ceeb los ntawm kev siv lub zog cia rau cov kev xav tau teb cov kev pab cuam (siv lub zog siv thaum lub sij hawm ncov), load leveling, thiab nws tus kheej siv lub zog tauj dua tshiab. Piv txwv li, cov kev tshawb fawb qhia tias cov tuam txhab lag luam, suav nrog cov hauv kev tsim cov hlau, tuaj yeem txiav lawv cov nqi hluav taws xob los ntawm 10-30% los ntawm kev siv cov tswv yim ntawm kev siv hluav taws xob, nyob ntawm seb lawv siv zog thiab cov nqi hluav taws xob hauv zos.

2. Txhawb nqa hluav taws xob ntawm cov txheej txheem kub kub
● Steel manufacturing nce zuj zus tshawb nrhiav cov fossil fuels nyob rau hauv high-kub siv hluav taws xob. BESS tuaj yeem khaws lub zog txuas ntxiv mus rau lub zog xws li cov tshuab tsis tu ncua, kom ntseeg tau tias kev siv hluav taws xob tseem muaj txiaj ntsig thiab txhim khu kev qha.

3. Txhim kho qhov cub Load Management
● Electric arc furnaces (EAFs) thiab lwm yam khoom siv uas xav tau siab ua rau lub zog nrawm nrawm. BESS smoothens cov kev hloov pauv no, txhim kho daim phiaj kev ruaj ntseg thiab txo kev nplua los ntawm kev siv hluav taws xob rau kev thov nce ntxiv.

4. Kev siv hluav taws xob rov ua dua tshiab rau ntawm qhov chaw
● Ntau cov nroj tsuag steel txais kev teeb tsa hnub ci lossis cua kom txo qis kev ua haujlwm. BESS kom ntseeg tau tias cov khoom siv hluav taws xob sib cuam tshuam tau siv tau zoo, khaws cia ntau lub zog rau kev siv tom qab thaum lub sijhawm poob.

5. Xauv Dynamic Pricing Strategies
● Kev Txhawb Nqa Hluav Taws Xob ntawm Cov Txheej Txheem Kub Kub: BESS tso cai rau cov nroj tsuag steel kom siv hluav taws xob siv hluav taws xob thaum lub sij hawm tus nqi qis tshaj plaws thiab khaws cia rau cov theem kev xav tau siab, txo cov nqi hluav taws xob hauv cov cheeb tsam nrog cov qauv nqi dynamic.

6. Txhim kho Supply Chain Resilience
● Lub zog cia tso cai rau cov nroj tsuag steel ua haujlwm thaum lub sijhawm hluav taws xob tsis zoo lossis cov kab hluav taws xob tsis ruaj khov, tswj kev tsim khoom thiab ua tau raws li cov neeg siv khoom xav tau txawm tias thaum muaj xwm txheej.

7. Ua kom muaj peev xwm ua kom muaj zog ecosystems
● Nrog BESS, cov nroj tsuag hlau tuaj yeem koom ua ke rau hauv lub zog sib koom hauv zos, muag cov khoom siv hluav taws xob ntau dhau rov qab rau hauv kab hluav taws xob lossis koom tes nrog cov lag luam nyob ze, txhawb kev ywj pheej ntawm lub zog hauv cheeb tsam.

8. Txo kev ntxhov siab ntawm Transformer
● Kev siv hluav taws xob hnyav hauv kev tsim cov hlau tuaj yeem ua rau cov khoom siv hluav taws xob ntau dhau, ua rau kev kho cov nqi qis thiab kev poob qis. BESS alleviates qhov kev ntxhov siab los ntawm kev ua raws li qhov tsis muaj, ncua kev hloov pauv lub neej.

9. Ua raws li Cov Cai Tswj Hluav Taws Xob
● Tsoomfwv xav tau kev lag luam uas siv hluav taws xob ntau ntxiv kom ua tau raws li cov pa roj carbon monoxide thiab kev ua haujlwm zoo. BESS pab txhawb kev ua raws li kev ua raws li qhov yuav tsum tau ua kom tau raws li cov qauv no kom tau txais txiaj ntsig zoo.

10. Txhim kho kev ua haujlwm ntawm kev twv ua ntej
● Cov nroj tsuag hlau feem ntau ntsib cov nqi hluav taws xob tsis zoo thiab cov sij hawm tsim khoom. BESS tso cai rau cov tswv lag luam los npaj kev siv hluav taws xob zoo dua, muab kev kwv yees ntau dua hauv kev ua haujlwm thiab txo kev pheej hmoo nyiaj txiag.

11. Ua kom muaj kev sib koom ua ke ntawm cov khib nyiab thaum tshav kub kub
● Steel mills tab tom tshawb nrhiav cov khoom siv hluav taws xob rov qab los txhim kho kev ua haujlwm. BESS tuaj yeem sib xyaw ua ke nrog cov tshuab no, khaws cov hluav taws xob tsim tawm los ntawm cov cua sov rov qab rau lwm cov nroj tsuag.
● Los ntawm kev hais txog cov txiaj ntsig no, koj tsab xov xwm tuaj yeem nthuav tawm qhov kev xav tshiab ntawm BESS cov kev daws teeb meem mus dhau qhov kev piav qhia ntawm kev txuag nqi thiab txo qis emissions, qhia txog lawv qhov tseem ceeb ntawm kev lag luam steel.
