Tsis ntev los no, Philippe Malbranche, Assistant Director-General ntawm International Photovoltaic Alliance, tau taw qhia ntawm lub rooj sib tham hauv kev lag luam tias tus nqi ntawm photovoltaic hydrogen ntau lawm yuav tsum qis li US $ 2 / kg thaum tus nqi sib tw ntawm cov phiaj xwm photovoltaic txuas ntxiv mus. tus nqi qis tshaj. Tus nqi ntawm hydrogen ntau lawm los ntawm fossil fuels yog piv.
Cov nqi hluav taws xob photovoltaic txuas ntxiv teeb tsa qis tshiab los txhawb kev txhim kho ntsuab hydrogen
Kev lag luam tsom xam lub koom haum Standard& Poor's Ntiaj teb no Platts tau hais los ntawm Philippe Malbranche hais tias tam sim no, ob feem peb ntawm cov nqi hluav taws xob tauj dua tshiab electrolyzed dej hydrogen ntau lawm los ntawm kev siv lub zog ntawm cov dej electrolyzed, thiab lwm 1/3 los ntawm lub electrolyzer. Qhov no txhais tau hais tias tus nqi tsim hluav taws xob los ntawm cov khoom siv hluav taws xob txuas ntxiv xws li cua fais fab thiab photovoltaics tam sim no yog qhov tseem ceeb ntawm cov nqi ntsuab hydrogen ntau lawm. Txhawm rau txo tus nqi ntsuab hydrogen, lub hom phiaj yog los txo tus nqi ntawm lub zog ntsuab.
& quot; Qhov tseeb, tam sim no, tus nqi tsim hluav taws xob photovoltaic hauv qee lub tebchaws thiab cheeb tsam tuaj yeem ncav cuag US $ 0.01-US $ 0.12 / kWh. Qhov no photovoltaic zog tsim cov lus hais yog txaus los muab Green Hydrogen kev lag luam thiab kev loj hlob muaj peev xwm. Photovoltaic hydrogen ntau lawm tau mus txog" qhov tseem ceeb" ntawm kev loj hlob loj." Philippe Malbranche tau hais.
Siv thaj av Gulf ua piv txwv, raws li International Renewable Energy Agency' cov kev suav, thaum pib ntawm 2020, Qatar Hluav Taws Xob thiab Hydropower's photovoltaic fais fab cog cov phiaj xwm kev lag luam tus nqi tau qis li 0.0157 US las / kWh. . Tus nqi qis photovoltaic yuav tsum ua rau thaj tsam Gulf ib qho kev xa tawm ntawm ntsuab hydrogen. av kub.
Tsis tas li ntawd xwb, raws li tsab ntawv ntsuam xyuas tau tshaj tawm los ntawm S& P Ntiaj Teb Platts thaum Lub Yim Hli xyoo no, nyob rau yav qab teb Australia, muaj qhov tshwm sim ntawm cov hluav taws xob photovoltaic ntau dhau rau qee lub sijhawm. Kev siv hluav taws xob photovoltaic los tsim cov hydrogen thiab ammonia tuaj yeem siv hluav taws xob ntau dhau. Green hydrogen, Green Ammonia project txawm offset ib feem ntawm cov nqi hluav taws xob noj, uas tau ntxiv txhim kho kev lag luam ntawm photovoltaic hydrogen ntau lawm.
Raws li qhov xwm txheej no, nrog rau kev txo qis hauv kev tsim cov nqi ntawm cov khoom siv hluav taws xob hauv ntiaj teb electrolyzed hydrogen ntau lawm, tus nqi ntawm photovoltaic hydrogen ntau lawm yuav tsum tshaj US $ 2 / kg cim thiab poob mus rau qib US $ 1.5-2 / kg, uas yog. feem ntau siab dua li tam sim no ntawm US $ 3. Qib ntau lawm ntawm USD / kg tau poob qis.
Kev sib tw ntawm fossil roj hydrogen ntau lawm yog" luv nqi"
Thaum tus nqi ntawm ntsuab hydrogen tseem poob qis, tus nqi ntawm hydrogen ntau lawm los ntawm fossil fuels yog nce. Thaum lub Kaum Ib Hlis Ntuj xyoo no, lub koom haum tshawb fawb kev lag luam ICIS tau tshaj tawm tsab ntawv ceeb toom hais tias tus nqi ntawm hydrogen ntau lawm los ntawm cov thee thiab cov nkev nkev hauv ntau lub tebchaws nyob sab Europe tau nce sai vim qhov nce ntawm cov nqi roj thiab cov nqi hluav taws xob. Tom qab lub caij ntuj no, tus nqi tsim khoom ntawm hydrogen los ntawm fossil fuels yog kwv yees li 5.5. Teb Chaws Asmeskas las / kg, qhov siab tshaj txawm tshaj 8 US dollars / kg; nyob rau hauv sib piv, tus nqi ntawm hydrogen ntau lawm los ntawm lub zog tauj dua tshiab tau ruaj khov nyob ib ncig ntawm 4 US dollars / kg rau lub sij hawm ntev. Nws yuav tsum tau muab sau tseg tias nyob rau hauv 2019, cov ntaub ntawv tso tawm los ntawm International Energy Agency tau qhia tias tus nqi ntawm hydrogen ntau lawm los ntawm cov thee thiab natural gas yeej tseem nyob rau theem ntawm US $ 1.7 / kg, uas kuj txhais tau hais tias tus nqi ntawm hydrogen ntau lawm los ntawm fossil. fuels tsawg kawg yog ob npaug rau xyoo no. Ntxuam.
Tsis tas li ntawd xwb, raws li British" Tus Saib Xyuas" tsab ntawv ceeb toom, yav dhau los, Australian National University tau tshaj tawm cov kev tshawb fawb qhia tias vim muaj cov pa roj carbon ntau ntawm cov pa roj carbon monoxide ntau lawm, tus nqi siab ntawm cov pa roj carbon emissions thiab kev pheej hmoo ntawm kev tso nyiaj fossil roj tso tseg kuj ua rau nws. Tus nqi yog siab dua li ntawm ntsuab hydrogen. Tsis tas li ntawd, qhov teeb meem methane emission ntawm hydrogen ntau lawm los ntawm cov nkev nkev yog qhov hnyav heev. Kev siv zog los tswj methane emission yuav ntxiv dag zog rau tus nqi grey hydrogen thiab xiav hydrogen.
Bridgetvan Dorsten, tus kws tshuaj ntsuam xyuas hluav taws xob hydrogen ntawm Wood Mackenzie, lub tuam txhab tshawb fawb kev lag luam, tau hais tias tsis ntev los no uas tau tsav los ntawm ntau yam, kev sib tw ntawm fossil fuel hydrogen ntau lawm xyoo no tau poob qis dua piv rau ib xyoos dhau los, thiab tus nqi sib tw ntawm lub ntiaj teb cua. -solar hydrogen ntau lawm tau zoo heev. .
Tus nqi ntawm photovoltaic hydrogen ntau lawm yuav poob 50% ua ntej 2025
Nyob rau hauv cov nqe lus ntawm electrolyzers, raws li qhov tseeb kev kwv yees tawm los ntawm Wood Mackenzie, los ntawm 2025, lub ntiaj teb no hydrogen ntau lawm nqi nyob rau hauv alkaline electrolyzers thiab proton exchange membrane electrolyzers yuav tsum poob los ntawm 35% thiab 50%, feem. Khoom oxide dej electrolysis Tus nqi ntawm lub tank yuav tsum" kuj tseem yuav poob qis rau rau rau yim xyoo tom ntej." Lub koom haum' qhov kev tshuaj ntsuam ntseeg tau hais tias qhov ntsuas ntawm cov dej electrolyzed hydrogen ntau lawm, kev nce hauv cov neeg koom nrog kev ua lag luam, thiab qib siab dua ntawm automation yuav dhau los ua txhua yam uas txhawb kev txo nqi ntawm electrolyzer manufacturing.
BridgetvanDorsten tau hais tias qhov txo qis ntawm qhov pib peev ntawm qhov project yuav pab txo qis cov nqi tsim khoom ntawm hydrogen. Ua ke nrog kev cog lus pheej yig pheej yig dua yuav khoom siv hluav taws xob thiab qib kev siv hluav taws xob ntsuab ntawm kev ua lag luam, kev ua lag luam muaj peev xwm ntawm kev sib tw hluav taws xob txuas ntxiv hluav taws xob hluav taws xob hydrogen tau pib tso tawm. Piv txwv li, nyob rau hauv cov teb chaws uas muaj ntau lub zog tauj dua tshiab, tus nqi ntawm lub zog tauj dua tshiab txawm tias yuav tsum tau txo qis ntxiv mus rau qib 0.01 USD / kWh, thiab tus nqi ntsuab hydrogen kuj tuaj yeem ruaj khov ntawm qib 1 USD / kg.
Nrog rau kev nthuav dav txuas ntxiv ntawm kev teeb tsa photovoltaic hauv cov tebchaws thoob plaws ntiaj teb, cov haujlwm tsim hluav taws xob photovoltaic hydrogen tseem raug tsim los tas li. Kev lag luam feem ntau kwv yees tias kev lag luam photovoltaic hydrogen ntau lawm yuav nthuav dav ntxiv rau kaum xyoo tom ntej, thiab nws tseem xav tias yuav" rov qab" photovoltaics thiab dhau los ua tus tsav tsheb tshiab rau kev loj hlob ntawm kev teeb tsa photovoltaic thoob ntiaj teb. zog.
Raws li cov ntaub ntawv tshaj tawm los ntawm Lub Chaw Haujlwm Saib Xyuas Hluav Taws Xob Thoob Ntiaj Teb, txij li xyoo 2020, lub ntiaj teb hydrogen tsim muaj peev xwm ntawm cov dej electrolyzed yog li 300,000 kilowatts, ntawm cov khoom siv hluav taws xob feem ntau yog hluav taws xob txuas ntxiv dua tshiab. Tsis tas li ntawd, kev txiav txim siab los ntawm cov phiaj xwm tshiab ntsuab hydrogen uas tau npaj tseg hauv ntau lub tebchaws, tag nrho txog 30 lub teb chaws tau npaj cov dej electrolyzed hydrogen tshiab. Nws kwv yees tias los ntawm 2026, lub ntiaj teb electrolyzed dej hydrogen muaj peev xwm yuav ncav cuag 1,700 kWh, uas tuaj yeem txhawb nqa. Lub zog tauj dua tshiab yuav ntxiv ib qho ntxiv 18 lab kilowatts lossis ntau dua ntawm lub peev xwm nruab. Ntawm lawv, Tuam Tshoj, Chile, Spain thiab Australia yuav dhau los ua tus thawj coj hauv tsib xyoos tom ntej rau cov khoom siv hydrogen tshiab los ntawm lub zog tauj dua tshiab, thiab lawv txoj kev lag luam yuav suav txog ntau dua 85% ntawm tag nrho lub ntiaj teb.
