Business aviation plays an important role in the FAA’s Continuous Lower Energy, 排放和噪音(清洁)计划, a series of government-industry partnerships designed to identify and implement environmental technologies aimed toward building on the operating efficiency of commercial turbine-powered aircraft. One prominent example of this work is the industry’s significant progress toward adopting viable and efficient, “drop-in” renewable-source alternatives to petroleum-based Jet A.
In 2013, NBAA joined with other industry groups and government stakeholders to launch the “Farm to Fly 2.0” initiative, which is aimed at developing viable, sustainable biofuel fuel supply chains in the U.S. to support an annual production goal of 1 billion gallons of alternative-sourced Jet A for aviation use by 2018. NBAA also is one of more than 300 members of the Commercial Aviation Alternative Fuels Initiative (CAAFI), which is dedicated to demonstrating the aviation industry’s commitment to environmental stewardship by creating a carbon-neutral air fleet by the year 2020.
到目前为止, alternative jet-fuel blending agents for commercial flight have utilized feedstocks from plants, 动植物油, biogas or biomass and conversion of sugars derived directly from plants or from hydrolyzed biomass. Future sources of these blending agents include other oils, sugars, cellulose and industrial waste.
Depending on the feedstock and approved conversion methodology, the resulting fuel is often blended with conventional Jet A (ranging from a 10- to 50-percent mix) to produce drop-in alternative fuels, though successful tests have also been conducted using 100-percent biofuel alternatives to Jet A.
一旦获得批准, these alternative fuels require no changes to maintenance and operating practices, 或者机组人员训练程序. 由行业利益攸关方进行的测试, including 制造商 of business aircraft and engines, also have demonstrated improvements to fuel burn, 并且显著减少了二氧化碳的排放.
商业航空面临着燃料成本, environmental and energy security challenges that arise from petroleum-based jet fuel use. Sustainable alternative jet fuels can help to address these challenges. Their use could reduce emissions that affect air quality and the global climate while expanding domestic energy sources that diversify fuel supplies, 有助于价格和供应的稳定, and generate economic development in rural communities. 请参阅 FAA正在进行的研究和支持 寻找A号喷气机的替代品.
CAAFI: The Commercial Aviation Alternative Fuels Initiative
CAAFI seeks to enhance energy security and environmental sustainability for aviation through alternative jet fuels. CAAFI is a coalition that focuses the efforts of commercial aviation to engage the emerging alternative-fuels industry. It enables its diverse participants – representing all the leading stakeholders in the field of aviation – to build relationships, 共享和收集数据, 确定资源, 和直接的研究, development and deployment of alternative jet fuels. 了解更多相关信息 joint industry effort to adopt and utilize viable biofuels.
