據(jù)烴加工網(wǎng)10月7日報道，美國能源部周五發(fā)布了一項計劃，詳細(xì)說明了政府范圍內(nèi)提高可持續(xù)航空燃料（SAF）生產(chǎn)和使用的戰(zhàn)略。

2021年9月，美國發(fā)起了一項政府挑戰(zhàn)，到2030年每年至少供應(yīng)30億加侖SAF，到2050年有足夠的SAF“以滿足100%的航空燃料需求，目前預(yù)計約為每年350億加侖”。美國航空公司已承諾與政府合作，到2030年向飛機(jī)運營商提供3億加侖SAF。

政府希望SAF與傳統(tǒng)燃料相比，至少減少50%的溫室氣體排放，并尋求擴(kuò)大供應(yīng)、使用、降低成本和增強(qiáng)其可持續(xù)性。

能源部長Jennifer Granholm表示，該計劃將幫助美國公司壟斷一個有價值的新興行業(yè)的市場。

美國能源部表示，鑒于實現(xiàn)2030年目標(biāo)的時間有限，需要立即將重點放在商業(yè)化的轉(zhuǎn)化技術(shù)和原料上。并補(bǔ)充道，脂質(zhì)途徑（脂肪、油和油脂）有望成為2030年之前的主要燃料途徑。

包括達(dá)美航空和西南航空在內(nèi)的許多航空公司都希望到2030年用SAF取代10%的航空燃料。

達(dá)美航空首席執(zhí)行官埃德·巴斯蒂安（Ed Bastian）表示，實現(xiàn)近期目標(biāo)“需要與我們的供應(yīng)商和政策制定者一起繼續(xù)努力，以便SAF能夠像傳統(tǒng)航空燃料一樣經(jīng)濟(jì)且廣泛可用”，而西南航空首席執(zhí)行長鮑勃·喬丹（Bob Jordan）則表示，SAF對于航空業(yè)脫碳至關(guān)重要。

航空業(yè)產(chǎn)生的二氧化碳排放量約占美國的2%，而美國航空業(yè)消耗的能源約占美國運輸能源的10%。

美國能源部表示，航空燃料以外的飛機(jī)動力來源，如電池技術(shù)和氫氣，預(yù)計在2050年之后才會對大幅減少航空排放作出貢獻(xiàn)。

U.S. outlines roadmap to boost sustainable aviation fuel

The U.S. Energy Department on Friday issued a plan detailing a government-wide strategy for ramping up production and use of sustainable aviation fuels (SAF).

In September 2021, the Administration launched a government challenge to supply at least 3 B gallons of SAF per year by 2030 and have enough SAF by 2050 "to meet 100% of aviation fuel demand, currently projected to be around 35 B gallons a year." U.S. airlines have pledged to work with the government to make 3 B gallons of SAF available to aircraft operators by 2030.

The administration wants SAF to achieve a minimum of a 50% reduction in GHG emissions compared to conventional fuel and seeks to expand supply, use, reduce its cost and enhance its sustainability.

Energy Secretary Jennifer Granholm said the "plan will help American companies corner the market on a valuable emerging industry."

The Energy Department said given limited time to meet the 2030 goals "requires an immediate focus on commercially ready conversion technologies and feedstocks." It added, "Lipid-based pathways (fats, oils, and greases) are expected to be the primary fuel pathway leading up to 2030."

Many airlines including Delta Air Lines and Southwest Airlines want to replace 10% of jet fuel with SAF by 2030.

Delta CEO Ed Bastian said hitting near-term goals "will require continued work alongside our suppliers and policymakers so that SAF can become as economical and widely available as traditional jet fuel," while Southwest CEO Bob Jordan said, "SAF is critical to decarbonizing the aviation sector."

Aviation generates approximately 2% of U.S. carbon dioxide emissions and U.S. aviation consumes approximately 10% of U.S. transportation energy.

The Energy Department said that sources to power airplanes other than jet fuels, such as battery technologies and hydrogen, "are not expected to contribute to substantially reducing aviation emissions until after 2050."
