Ntawm Hydrogen thiab Lithium—Kev Nres Ntawm Cov Ntawv Ntawv
Thiab yuav tsum tau txais kev sib tham rau qhov kev hloov mus rau Net-Zero ntawm cov kev lag luam ntawm lub ntiaj teb, qhov kev nrhiav lwm cov khoom uas tuaj yeem muaj kev siv ntau, nyob nruab nrab ntev thiab tsis muaj kev pheej yig rau qhov kev siv ntau, thiab tsis muaj kev pheej yig rau qhov kev siv ntau. Ntawm qhov hydrogen thiab lithium-ion batteries yog qhov tseem ceeb, ib qho tshwj xeeb uas tau los ua dua: Metal Iron Powder.
Qhov kev xav ntawm iron energy yog zoo thiab sib koo: iron yog qhov khoom uas tuaj yeem muaj kev siv ntau, muab kev ntxiv ntau thiab kev ntxiv ntau los ntawm oxidation combustion, thiab tom qab ntawd "recharged" dua mus rau iron powder los ntawm reduction nrog green hydrogen. Qhov "Iron—Iron Oxide—Iron" closed-loop system no muaj kev siv tau rau kev siv ntau rau kev lag luam thiab kev siv ntau rau ntawm qhov sib koo ntawm lub hlis.
I. Cov pov tseg ntawm cov pov tseg uas muaj ntau dua: Qhov tseem ceeb ntawm qhov kev sib txuas pov tseg
Tsis txawm cov pov tseg txhua yam tuaj yeem siv rau hauv kev siv hluav taws xob. Tsis zoo li kev ua pov tseg tseem ceeb, cov pov tseg uas muaj ntau dua yuav tsum tau txais cov kev kawm tshaj plij: qhov puas tsuaj ≥98%, qhov loj ntawm cov pov tseg (20–100μm), thiab qhov ua haujlwm ntau. Nyob rau hauv no, muaj peb qhov kev ua pov tseg uas nyob rau hauv qhov kev sib txuas pov tseg ntawm lub ntiaj teb:
Kev txo cov pov tseg ntawm cov pov tseg uas muaj ntau dua (Kev ua pov tseg uas muaj ntau dua thiab muaj ntau dua): Cov pov tseg uas muaj ntau dua yog ua kom puas tsuaj thiab txo los ntawm hluav taws xob uas muaj ntau dua nyob rau hauv qhov ceev 600–900°C kom ua cov pov tseg uas muaj ntau qhov kho. No yog qhov kev ua pov tseg uas muaj ntau dua thiab muaj ntau dua rau kev siv hauv qhov kev ua pov tseg uas muaj ntau dua.
Kev siv dua cov pov tseg uas muaj ntau dua (Kev siv dua uas muaj ntau dua thiab muaj ntau dua): Cov pov tseg uas muaj ntau dua yog ua kom muaj ntau dua thiab ua cov pov tseg uas muaj ntau dua los ntawm cov dej uas muaj ntau dua thiab cov dej uas muaj ntau dua. Qhov kev ua no muaj qhov ntau dua thiab muaj ntau dua rau hauv cov kev kawm ESG (Environmental, Social, and Governance) ntawm cov kev ua pov tseg uas muaj ntau dua.
Kev sib sau cov khoom (Kev kho tshwj xeeb zoo tshaj plaws): Througj kev soj qhov cua ntawm cov khoom sib xyaw li cov khoom iron carbonyl, cov pov tseg zoo tshaj plaws los sis tshaj thiab cov pov tseg nano-scale tau ua los. Cov no muaj kev sib xyaw thiab kev soj qhov cua zoo tshaj plaws, nyob rau hauv cov khoom siv hluav tais uas muaj kev siv tswv yim tshaj plaws.
II. Kev soj qhov cua zoo tshaj plaws: 1500°C Qhov cua tsis muaj carbon
Cov pov tseg iron yog nyob rau hauv kev siv los yog "kev kho tshwj xeeb uas tsis muaj txoj haujlwm" rau cov boiler uas siv coal thiab gas. Througj kev siv lub system pneumatic conveying zoo tshaj plaws thiab lub system feeding closed-loop, cov pov tseg iron tau sib xyaw nrog lub cua uas tau muaj cua soj qhov cua lawm thiab tau soj qhov cua.
Qhov cua zoo tshaj plaws: Kev soj qhov cua tau reach 1200–1500°C, ua qhov cua soj qhov cua zoo tshaj plaws rau cov turbine steam lossis rau kev siv hauv tsev sib kho.
Tsus muaj kev tso cua: Kev siv no tsis muaj CO2 thiab SOx. Qhov khoom uas tau ua los yog cov pov tseg iron oxide (rust) tsis muaj kev siv, uas tau muaj kev tso cua 100% los ntawm cov filter baghouse.
Safely & Stability: Tsis zoo li hydrogen uas yuav muaj kev cuam tshuam, pov tseg iron yog stability nyob rau hauv qhov cua ntuj, tsis muaj kev loss ntawm kev ntxhiab, thiab tsis muaj kev nyuaj siab rau kev kho tawm nyob rau hauv lub sijhawm ntev.
III. Lub Energy Logic: Kev txhim kho energy rau hauv lub sijhawm ntev
Lub kev tswj hwm ntawm iron energy yog rau hauv "Infinite Circularity." Nws ua haujlwm raws li "Solid-State Battery":
Lub "Charge" Phase: Thaum muaj ntau ntau wind loss thiab solar energy, cov electricity xwb tsis muaj kev nyuaj siab los ua hydrogen, uas yuav txhawb iron oxide kom mus rau hauv metal iron powder, uas tau ua kev kho energy nyob rau hauv chemical form.
Lub "Discharge" Phase: Thaum muaj ntau ntau kev xav tau loss thiab hauv lub sijhawm ntuj npau, cov iron powder yuav raug txhawb kom muaj heat rau hauv kev xav tau.
Thaum lub RTE (Round-Trip Efficiency) ntawm lawv yog 35% rau 50%, iron powder yog zoo heev rau kev kho energy rau hauv lub sijhawm ntuj npau thiab kev txhim kho rau hauv qhov chaw ntsuas, thaum cov cost ntawm lithium-ion batteries loss thiab hydrogen pipelines yuav muaj kev nyuaj siab heev.
