Ntiaj teb no Biofuel Policy Initiatives: Cov Kev Txhim Kho Tseem Ceeb thiab Cov Qauv
Tshaj li rau lub hlis dhau los, Lub Chaw Haujlwm Saib Xyuas Hluav Taws Xob Thoob Ntiaj Teb (IEA tau tshaj tawm cov kev nce qib tseem ceeb hauv kev lag luam biofuel thoob ntiaj teb, suav nrog bioethanol, biodiesel, rov siv tau roj av, thiab cov roj zaub hydrogenated (HVO. Cov kev nce qib no yog tsav los ntawm kev hloov pauv txoj cai, kev tsim kho thev naus laus zis, thiab hloov pauv kev lag luam.
Lub teb chaws -Txoj cai hloov tshiab:
Brazil: Thaum Lub Kaum Hli 2024, Brazil tau tshaj tawm Txoj Cai Lij Choj Yav Tom Ntej, uas nce kev sib xyaw ua haujlwm rau ethanol thiab biodiesel, qhia txog lub hom phiaj ntawm lub tsev cog khoom rau kev lag luam aviation, thiab tsim kom muaj lub teb chaws ntsuab diesel.
European Union: EU tau pom zoo tsab ntawv ceeb toom Renewable Energy Directive III (RED III hauv 2023, ob npaug ntawm lub zog tauj dua tshiab hauv kev thauj mus rau 29% los ntawm 2030-lossis 14.5% txo qis hauv tsev cog khoom roj siv.
Is Nrias teb: Lub Kaum Ib Hlis 2023, Is Nrias teb tau tshaj tawm qhov yuav tsum tau ua kom cov roj biogas sib xyaw ua haujlwm pib txij xyoo 2025-2026, nce mus rau 5% los ntawm 2028-2029. Biogas thiab compressed biogas noj yog npaj kom nce ze li ntawm 90% los ntawm 2023 qib los ntawm 2030.
Kenya: Hauv xyoo 2024, Kenya tau tshaj tawm National Cooking Transformation Strategy, lub hom phiaj kom ua tiav kev nkag mus rau kev siv hluav taws xob huv los ntawm 2028, nrog rau qhov tseem ceeb ntawm biomass qhov cub thiab bioethanol.
Technological Progress thiab Feedstock Challenges
Kev nce qib hauv biofuel thev naus laus zis yog qhov tseem ceeb los ua kom muaj txiaj ntsig zoo. Thaum txoj kev lag luam xws li pob kws - thiab qab zib -raws li ethanol, FAME biodiesel, thiab HVO tau tsim tau zoo, cov thev naus laus zis los hloov cov lignocellulosic thiab herbaceous biomass rau hauv cov kua biofuels tseem tshwm sim.
Cov txheej txheem zoo li biomass gasification ua raws li Fischer-Tropsch synthesis (bio-FT, hydrothermal liquefaction, thiab pyrolysis ceev yog nyob rau ntau theem ntawm kev txhim kho. Piv txwv li, Bayou Fuels biorefinery hauv Tebchaws Meskas npaj yuav suav nrog carbon capture thiab cia kom ua tiav cov pa phem.
Txawm li cas los xij, kev muaj thiab kev siv cov khoom noj khoom haus ruaj khov tseem yog qhov nyuaj. Advanced feedstocks-xws li siab, siv roj ua noj, khoom noj khib nyiab, thiab qoob loo seem-tam sim no tsuas yog 12% ntawm biofuel ntau lawm. IEA cov haujlwm uas ze li 40% ntawm biofuel ntau lawm yuav tsum tau los ntawm cov peev txheej no los ntawm 2030, uas yuav xav tau ob qho tib si kev txhim kho thev naus laus zis thiab txhim kho cov khoom sau.
Kev txiav txim siab nyiaj txiag thiab kev ua lag luam Outlook
Biofuels feem ntau kim dua fossil fuels, tab sis lawv qhov cuam tshuam rau qhov kawg- cov nqi roj tau qis qis: dhau 13 xyoo dhau los, cov nqi muag khoom hauv khw loj xws li Asmeskas, Brazil, Europe, Indonesia, thiab Is Nrias teb tau nce tsuas yog $ 0.01 txog $ 0.04 ib liter sib npaug.
Tsoomfwv tau ua haujlwm ntau yam cuab yeej los txuas rau tus nqi sib txawv, suav nrog cov nyiaj pab, kev txhawb nqa se, thiab cov khoom siv ethanol los ua kom cov neeg tsim khoom muaj txiaj ntsig.
Txawm hais tias tus nqi siab dua, kev thov rau biofuels yuav tsum loj hlob. Cov neeg Esxias biofuel ntau lawm tau kwv yees kom dhau Tebchaws Europe los ntawm 2026, txhawb nqa los ntawm kev sib xyaw ua haujlwm hauv Indonesia, Malaysia, thiab Is Nrias teb. Is Nrias teb lub hom phiaj kom ua tiav 20% ethanol sib xyaw tus nqi xyoo no, tso nws ua lub ntiaj teb thib peb - lag luam ethanol loj tshaj plaws.
Hauv Teb Chaws Asmeskas, HVO thiab cov roj aviation ruaj khov (SAF xav tias yuav tsim 78% ntawm kev loj hlob ntawm biofuel xav tau los ntawm 2026. Kev tsim khoom hauv tsev yog teem kom tau raws li feem ntau ntawm qhov kev thov tshiab no, nrog rau ob peb qhov kev tshem tawm txawm tias cov nqi khoom noj siab.
Tebchaws Europe cov khoom siv hluav taws xob txuas ntxiv txuas ntxiv tau nthuav dav xyoo no, pab los ntawm kev tswj hwm kev txhawb nqa thiab kev thov nce ntxiv. Kev noj haus tau kwv yees tias yuav nce li ntawm 26% siab dua 2024 qib, thaum kev tsim khoom tau npaj kom loj hlob li ntawm 16% ua tsaug rau kev nthuav dav ntau lawm thoob plaws cheeb tsam. Txawm li cas los xij, cov kev sib tw xws li kev lag luam khoom noj khoom haus tsis hloov pauv thiab nce tus nqi tseem muaj.
Sector-Kev txhim kho tshwj xeeb
Aviation: Lub aviation sector tau nce kev txhawb nqa rau biofuels. EU's ReFuelEU teg num xav kom cov neeg xa khoom siv roj suav nrog 2% SAF los ntawm 2025, nce mus rau 6% los ntawm 2030. HEFA-SPK, tsim los ntawm cov roj ua noj, tam sim no yog hom roj aviation ruaj khov tshaj plaws.
Maritime: Kev xa khoom xa tuaj ntsib cov teeb meem hauv kev siv roj biofuel vim tsis muaj cov neeg xav tau tshiab ntau dhau ntawm EU cov cai. IEA sau tseg txog 40% qhov tsis txaus ntawm biofuel noj piv rau nws qhov Net Zero los ntawm 2050 qhov xwm txheej. Txawm li cas los xij, kev txiav txim siab txoj cai ntsuas- xws li emissions pricing mechanisms los ntawm International Maritime Organization (IMO hauv 2025- tuaj yeem txhawb nqa tau.

Lub ntiaj teb biofuel toj roob hauv pes yog hloov zuj zus mus sai, nrog rau cov thawj coj tseem ceeb ntawm txoj cai, kev txhim kho thev naus laus zis, thiab kev hloov pauv kev lag luam tau pom nyob rau lub hlis dhau los. Txawm hais tias muaj teeb meem cuam tshuam txog kev muaj khoom noj khoom haus thiab kev muaj peev xwm ntawm kev lag luam, kev lag luam qhia tau hais tias muaj peev xwm loj hlob muaj zog -tshwj xeeb hauv cheeb tsam xws li Asia thiab kev lag luam xws li aviation. Kev txhawb nqa txuas ntxiv los ntawm txoj cai, kev tsim kho tshiab, thiab kev nqis peev yuav yog qhov tseem ceeb los ua kom tau raws li lub ntiaj teb biofuel ntau lawm thiab cov hom phiaj kev ruaj khov.
