据烃加工网8月16日报道，全球海事脱碳中心（GCMD）周二表示，在一艘双燃料液化石油气（LPG）运输船的试验中，发现使用植物油生物燃料混合物比使用超低硫燃料油（VLSFO）可减少20%的净碳排放。
这是GCMD进行的五个供应链燃料试验中的第三个，该试验是一项耗资1800万美元项目的一部分，旨在测试不同的生物燃料混合物以减少碳排放。
这些试验是帮助燃料和航运行业提供绿色燃料以满足国际海事组织2030年和2050年脱碳目标的关键。
在最近的试验中使用的生物燃料混合物包括船用柴油与30%由100%的废物和残渣生产的加氢处理植物油（HVO）混合。
GCMD在一份声明中表示，与使用基于化石的船用柴油相比，使用HVO可以减少83%的排放。
生产商GoodFuels向东太平洋航运公司运营的中型天然气运输船Kaupang提供了约200吨混合生物燃料。
与此同时，将船用柴油与30%的生物燃料混合作为液化石油气燃烧的试点燃料，与使用极低硫燃料油相比，可以减少20%的净排放量；同时，向示踪剂中加入HVO，并在燃料船上与船用柴油混合，以监测来源和数量。
GoodFuels商业总监Johannes表示，随着现在开始将新一代可持续海洋燃料推向市场，透明度变得更加重要。
先前的试验涉及将废食用油甲酯(UCOME)分别与极低硫燃料油和高硫燃料油混合。
在全球最大的燃油中心之一新加坡，生物燃料燃油销量呈上升趋势，7月份生物混合低硫燃料油销量攀升至单月历史高位。

Decarbonization group's biofuel bunkering trial finds 20% drop in emissions
The Global Center for Maritime Decarbonization (GCMD) found net carbon emissions fell 20% using a vegetable oil biofuel blend compared with very low sulfur fuel oil (VLSFO) in a trial for a dual-fuel liquefied petroleum gas (LPG) carrier, the center said on Tuesday.
This was the third of five supply chain bunkering trials that the GCMD has undertaken as part of an $18-MM project to test different biofuel blends to reduce carbon emissions.
The trials are key to helping the fuel and shipping industries come up with green fuels to meet the International Maritime Organization’s 2030 and 2050 decarbonization targets.
The biofuel blend used in the latest trial comprised marine gasoil blended with 30% hydrotreated vegetable oil (HVO) that was produced from 100% waste and residues.
Using the HVO resulted in an 83% reduction in emissions compared to using fossil-based marine gasoil, the GCMD said in a statement.
GoodFuels supplied about 200 metric tons of the biofuel blend to the mid-sized gas carrier Kaupang operated by Eastern Pacific Shipping.
Meanwhile, blending marine gasoil with 30% biofuel as a pilot fuel for LPG combustion led to a 20% net reduction in emissions versus sailing on very low sulfur fuel oil.
A tracer was dosed with the HVO and blended with marine gasoil onboard the bunker vessel for origin and quantity monitoring.
"Transparency is becoming even more crucial as we are now starting to bring the new generation of sustainable marine fuels to market," said Johannes, commercial director at GoodFuels.
The remaining supply chain trials will be run in the next few months, while details of the assurance framework will be shared through a public report in early 2024, according to GCMD.
Previous trials involved blends comprising used cooking oil methyl ester (UCOME) blended with very low sulfur fuel oil and high sulfur fuel oil respectively.
Biofuel bunkering volumes have trended higher at the world's top bunker hub, Singapore, with bio-blended low sulfur fuel oil sales climbing to a monthly record high in July.
