据烃加工网10月7日报道，美国能源部周五发布了一项计划，详细说明了政府范围内提高可持续航空燃料（SAF）生产和使用的战略。
2021年9月，美国发起了一项政府挑战，到2030年每年至少供应30亿加仑SAF，到2050年有足够的SAF“以满足100%的航空燃料需求，目前预计约为每年350亿加仑”。美国航空公司已承诺与政府合作，到2030年向飞机运营商提供3亿加仑SAF。
政府希望SAF与传统燃料相比，至少减少50%的温室气体排放，并寻求扩大供应、使用、降低成本和增强其可持续性。
能源部长Jennifer Granholm表示，该计划将帮助美国公司垄断一个有价值的新兴行业的市场。
美国能源部表示，鉴于实现2030年目标的时间有限，需要立即将重点放在商业化的转化技术和原料上。并补充道，脂质途径（脂肪、油和油脂）有望成为2030年之前的主要燃料途径。
包括达美航空和西南航空在内的许多航空公司都希望到2030年用SAF取代10%的航空燃料。
达美航空首席执行官埃德·巴斯蒂安（Ed Bastian）表示，实现近期目标“需要与我们的供应商和政策制定者一起继续努力，以便SAF能够像传统航空燃料一样经济且广泛可用”，而西南航空首席执行长鲍勃·乔丹（Bob Jordan）则表示，SAF对于航空业脱碳至关重要。
航空业产生的二氧化碳排放量约占美国的2%，而美国航空业消耗的能源约占美国运输能源的10%。
美国能源部表示，航空燃料以外的飞机动力来源，如电池技术和氢气，预计在2050年之后才会对大幅减少航空排放作出贡献。

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."
