面向交通深度脱碳的先进生物液体燃料发展研究OA

Advanced bio-liquid represent a critical complementary pathway for achieving deep decarbonization in the transportation sector,and hold significant strategic values particularly in sectors that are difficult to electrify,such as aviation,shipping,and certain heavy-duty transportation.This study systematically analyzes the development positioning,resource base,technical pathways,and emission reduction potentials of advanced bio-liquid fuels in China.It assesses the reserves of non-food biomass resources,such as waste oils/fats and lignocellulosic biomass,as well as the development prospects of major technical pathways,including biodiesel,Fischer-Tropsch fuels,alcohol-based jet fuel,and bio-methanol.The study indicates that the use of advanced bio-liquid fuels could reduce emissions by approximately 2.34×108 tCO2 by 2060.Among these,the contribution of road transportation to emission reductions will gradually decline as electrification progresses,while sustainable aviation fuels and low-carbon marine fuels will become key avenues for future emissions reductions in the transportation sector.Although waste oils/fats offer advantages for near-term deployment,their resource scale is limited.In the medium to long term,efforts must gradually expand toward lignocellulosic and synthetic fuel pathways.In the future,China needs to establish mechanisms for feedstock supply,life-cycle carbon accounting,and green fuel markets to promote the coordinated development of advanced biofuels with electrification and hydrogen energy,thereby providing support for deep decarbonization in the transportation sector.
