Hydrogen ntau lawm los ntawm dej electrolysis feem ntau yog muab faib ua AWE, khoom polymer PEM dej electrolysis, khoom polymer anion exchange membrane (AEM) dej electrolysis, thiab khoom oxide (SOE) dej electrolysis. Ntawm lawv, AWE yog qhov ntxov tshaj plaws industrialized dej electrolysis thev naus laus zis nrog ntau xyoo ntawm daim ntawv thov kev paub thiab yog qhov paub tab tshaj plaws; PEM dej electrolysis thev naus laus zis tau tsim kho sai nyob rau xyoo tas los no, SOE dej electrolysis thev naus laus zis yog nyob rau theem pib ua qauv qhia, thiab AEM dej electrolysis kev tshawb fawb nyuam qhuav pib.
Los ntawm lub sijhawm teev, AWE thev naus laus zis yog qhov yooj yim rau kev xa tawm thiab siv sai sai hauv kev daws qhov ze ntawm kev siv lub zog tauj dua tshiab; tab sis los ntawm kev pom zoo, PEM dej electrolysis tshuab muaj qhov ceev tam sim no, me me ntawm electrolyzer, kev ua haujlwm yooj yim, thiab muaj kev hloov pauv sai. Nws muaj qhov zoo sib xws nrog cua zog thiab photovoltaic (lub zog tsim muaj ntau dua volatility thiab randomness). Nrog rau qhov nrov thiab kev siv ntawm PEM electrolyzer, nws cov nqi yuav tsum poob sai, uas yuav tsum yog qhov kev loj hlob ntawm 5 ~ 10a tom ntej. Kev txhim kho ntawm SOE thiab AEM dej electrolysis nyob ntawm qhov kev sib tw ntawm cov khoom siv thev naus laus zis.
