據阿拉伯貿易網1月25日報道，由阿聯酋可再生能源公司馬斯達爾公司、法國能源巨頭道達爾能源公司、德國西門子能源公司和日本丸紅公司組成的聯盟宣布，馬斯達爾公司主導的綠色氫氣生產可持續航空燃料（SAF）計劃正在積極與許可方合作，以認證甲醇生產SAF的新途徑。

這種新途徑將為滿足全球生產SAF的需求提供另一種選擇，并幫助航空業脫碳。

這個聯盟一直在與阿布扎比能源部、阿提哈德航空公司、漢莎航空集團和哈利法科技大學合作，開展e-SAF的示范項目。

自2021年1月以來，這個倡議的合作伙伴已經完成了對技術供應商、可行性研究和概念設計的一系列評估，同時與監管機構就合規問題密切合作。目前，這個聯盟已將甲醇制航空燃料(MTJ)的路徑作為其選擇的技術路線。

乙醇制航空燃料合成石蠟煤油途徑(ATJ-SPK)已于2016年通過認證，符合國際航空燃料標準。這個途徑包括幾種醇，如乙醇和異丁醇。

這個聯盟的目標是通過將甲醇(化學工業的關鍵組成部分)納入其職權范圍，擴大這一途徑所涵蓋原料醇的范圍。雖然MTJ途徑的各個組成部分在很大程度上是成熟的技術，但它們還沒有被集成到SAF中，而且這一途徑還沒有獲得認證。這個聯盟現在將與MTJ技術的許可方合作，盡快獲得這種新途徑的認證。

可持續航空燃料是一種立即可用的解決方案，可顯著降低航空運輸的二氧化碳排放。它可以作為一種臨時燃料，無需改裝現有的存儲和加油基礎設施、飛機或發動機。在全球范圍內逐步采用生物航空燃料將有助于顯著降低航空運輸的二氧化碳排放量，因為從廢物和殘渣中生產生物航空燃料在其生命周期內平均減少80%的二氧化碳排放量。

Masdar to certify a novel pathway to make SAF from methanol

A consortium of Masdar, TotalEnergies, Siemens Energy and Marubeni has announced that the Masdar-led initiative focused on green hydrogen to produce SAF is actively working with licensors to certify a new production pathway for SAF from methanol.

This novel pathway will provide one more option to address the global need to produce and make SAF available globally and help the aviation industry decarbonise.

The consortium has been collaborating with the Abu Dhabi Department of Energy, Etihad Airways, Lufthansa Group, and Khalifa University of Science and Technology, on a demonstration initiative for e-SAF.

Since January 2021, the partners in the initiative have completed a range of evaluations on technology suppliers, feasibility studies and conceptual designs, while working closely with regulators on compliance issues. The consortium has now zoned in on the methanol to jet (MTJ) pathway as its chosen technology route.

The Alcohol to Jet Synthetic Paraffinic Kerosene pathway (ATJ-SPK) has been certified in 2016 as meeting international standards for jet fuel. This pathway covers several alcohols like ethanol and iso-butanol.

The objective of the consortium is to widen the range of alcohols covered in this pathway by getting methanol, a key building block in the chemical industry, included in its remit. Although the individual components of the MTJ pathway are for the most part mature technologies, they have not yet been integrated for the purposes of making SAF and this route is not yet certified. The consortium will now work together with licensors of the MTJ technology, to get this novel pathway certified at the earliest.

Sustainable Aviation Fuel (SAF): Sustainable aviation fuel is an immediately available solution for significantly reducing the CO2 emissions of air transportation. It can be used as a drop-in fuel without modifying existing storage and refueling infrastructure, aircraft or engines. Gradual incorporation worldwide should help significantly lower the CO2 emissions of air transportation since, on average, biojet fuel produces 80 per cent fewer CO2 emissions over its lifecycle when produced from waste and residue.
