Dab tsi yog nuclear hydrogen ntau lawm?

Nuclear hydrogen ntau lawm yog dav suav hais tias yog txoj kev nyiam tshaj plaws rau kev tsim cov hydrogen loj, tab sis nws zoo li tau nce qeeb. Yog li, dab tsi yog nuclear hydrogen ntau lawm?

Nuclear hydrogen ntau lawm, uas yog, nuclear reactor ua ke nrog cov txheej txheem hydrogen siab heev, rau cov khoom loj ntawm hydrogen. Hydrogen ntau lawm los ntawm nuclear zog muaj qhov zoo ntawm tsis muaj tsev cog khoom gases, dej raws li raw khoom, high efficiency thiab loj teev, yog li nws yog ib qho tseem ceeb kev daws rau loj-scale hydrogen mov nyob rau hauv lub neej yav tom ntej. Raws li IAEA kwv yees, me me 250MW reactor tuaj yeem tsim tau 50 tons ntawm hydrogen ib hnub twg siv cov tshuaj tiv thaiv nuclear kub.

Lub hauv paus ntsiab lus ntawm hydrogen ntau lawm nyob rau hauv nuclear zog yog siv lub tshav kub generated los ntawm nuclear reactor raws li lub zog qhov chaw rau hydrogen ntau lawm, thiab kom paub txog npaum thiab loj-scale hydrogen ntau lawm los ntawm kev xaiv tsim nyog technology. Thiab txo lossis txawm tias tshem tawm cov pa hluav taws xob hauv tsev cog khoom. Lub schematic daim duab ntawm hydrogen ntau lawm los ntawm nuclear zog yog qhia nyob rau hauv daim duab.

Muaj ntau txoj hauv kev los hloov hluav taws xob nuclear rau hydrogen zog, suav nrog dej ua raw khoom los ntawm electrolysis, thermochemical voj voog, kub kub chav electrolysis hydrogen ntau lawm, hydrogen sulfide li raw khoom tawg hydrogen ntau lawm, nkev roj, thee, biomass li raw khoom pyrolysis hydrogen. kev tsim khoom, thiab lwm yam. Thaum siv dej ua raw khoom, tag nrho cov txheej txheem hydrogen tsis tsim CO₂, uas tuaj yeem tshem tawm cov pa hluav taws xob hauv tsev cog khoom; Ua hydrogen los ntawm lwm qhov chaw tsuas yog txo cov pa roj carbon monoxide. Tsis tas li ntawd, kev siv cov dej hauv nuclear electrolysis tsuas yog ib qho yooj yim ua ke ntawm kev tsim hluav taws xob nuclear thiab cov khoom siv hluav taws xob ib txwm muaj, uas tseem nyob rau thaj tsam ntawm kev tsim hluav taws xob nuclear thiab feem ntau tsis suav tias yog qhov tseeb nuclear hydrogen ntau lawm technology. Yog li ntawd, lub voj voog thermochemical nrog dej raws li cov khoom siv raw, tag nrho lossis ib feem ntawm kev siv hluav taws xob nuclear thiab kub kub chav electrolysis yog suav tias yog sawv cev rau yav tom ntej kev taw qhia ntawm nuclear hydrogen ntau lawm technology.

Tam sim no, muaj ob txoj hauv kev tseem ceeb ntawm hydrogen ntau lawm hauv nuclear zog: electrolytic dej hydrogen ntau lawm thiab thermochemical hydrogen ntau lawm. Nuclear reactors muab hluav taws xob thiab hluav taws xob hluav taws xob raws li ob txoj hauv kev ntawm hydrogen ntau lawm.

Electrolysis ntawm dej los tsim hydrogen yog siv lub zog nuclear los tsim hluav taws xob, thiab tom qab ntawd los ntawm cov khoom siv dej electrolytic kom decompose dej rau hauv hydrogen. Hydrogen ntau lawm los ntawm cov dej electrolytic yog ib qho ncaj qha hydrogen ntau lawm txoj kev, tab sis cov hydrogen ntau lawm efficiency ntawm txoj kev no (55% ~ 60%) yog tsawg, txawm hais tias lub siab tshaj plaws SPE dej electrolysis technology yog saws nyob rau hauv lub tebchaws United States, lub electrolytic efficiency. yog nce mus rau 90%. Tab sis txij li feem ntau nuclear fais fab nroj tsuag tam sim no tsuas yog hloov cov cua sov rau hluav taws xob ntawm ib ncig ntawm 35% kev ua haujlwm, qhov kawg tag nrho kev ua haujlwm ntawm hydrogen los ntawm dej electrolysis hauv nuclear zog tsuas yog 30%.

Thermal-chemical hydrogen ntau lawm yog raws li thermal-chemical voj voog, coupling ib tug nuclear reactor nrog ib tug thermal-chemical voj voog hydrogen ntau lawm ntaus ntawv, siv lub siab kub muab los ntawm lub nuclear reactor raws li ib tug kub qhov chaw, yog li ntawd cov dej catalyzes thermal decomposition ntawm 800 ℃. mus txog 1000 ℃, thiaj li tsim tau hydrogen thiab oxygen. Piv nrog rau electrolytic dej hydrogen ntau lawm, thermo chemical hydrogen ntau lawm efficiency yog siab dua, tag nrho cov efficiency yuav tsum ncav cuag ntau tshaj 50%, tus nqi qis dua.
