據(jù)烴加工網(wǎng)8月16日報道，全球海事脫碳中心（GCMD）周二表示，在一艘雙燃料液化石油氣（LPG）運輸船的試驗中，發(fā)現(xiàn)使用植物油生物燃料混合物比使用超低硫燃料油（VLSFO）可減少20%的凈碳排放。

這是GCMD進(jìn)行的五個供應(yīng)鏈燃料試驗中的第三個，該試驗是一項耗資1800萬美元項目的一部分，旨在測試不同的生物燃料混合物以減少碳排放。

這些試驗是幫助燃料和航運行業(yè)提供綠色燃料以滿足國際海事組織2030年和2050年脫碳目標(biāo)的關(guān)鍵。

在最近的試驗中使用的生物燃料混合物包括船用柴油與30%由100%的廢物和殘渣生產(chǎn)的加氫處理植物油（HVO）混合。

GCMD在一份聲明中表示，與使用基于化石的船用柴油相比，使用HVO可以減少83%的排放。

生產(chǎn)商GoodFuels向東太平洋航運公司運營的中型天然氣運輸船Kaupang提供了約200噸混合生物燃料。

與此同時，將船用柴油與30%的生物燃料混合作為液化石油氣燃燒的試點燃料，與使用極低硫燃料油相比，可以減少20%的凈排放量；同時，向示蹤劑中加入HVO，并在燃料船上與船用柴油混合，以監(jiān)測來源和數(shù)量。

GoodFuels商業(yè)總監(jiān)Johannes表示，隨著現(xiàn)在開始將新一代可持續(xù)海洋燃料推向市場，透明度變得更加重要。

先前的試驗涉及將廢食用油甲酯(UCOME)分別與極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，生物燃料燃油銷量呈上升趨勢，7月份生物混合低硫燃料油銷量攀升至單月歷史高位。

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.
