Renewable jet fuel, also known as sustainable aviation fuel (SAF), is an eco-friendly biofuel specifically designed to power aircraft. It possesses similar properties to traditional jet fuel but with a significantly reduced carbon footprint. By employing various feedstock options and advanced production technologies, SAF has the potential to considerably decrease greenhouse gas (GHG) emissions throughout its life cycle, surpassing the environmental performance of conventional jet fuel. In fact, certain emerging pathways for SAF even exhibit a net-negative GHG footprint.
Due to their lower carbon intensity, SAFs play a crucial role in mitigating GHG emissions in the aviation sector, which accounts for approximately 9%–12% of transportation-related GHG emissions in the United States, as reported by the U.S. Environmental Protection Agency.
What are the Benefits of Renewable Jet Fuel Beyond?
The utilization of this fuel, in place of conventional jet fuel, offers a range of advantages that extend beyond the mere reduction of greenhouse gas (GHG) emissions. The growth, sourcing, and production of renewable jet fuel from sustainable and waste resources can create new economic prospects in agricultural communities, improve the environment, and even enhance aircraft performance.
1. Additional Revenue for Farmers
Through the cultivation of biomass crops specifically for renewable jet fuel production, American farmers can generate supplementary income during off seasons by supplying feedstocks to this emerging market. Simultaneously, they can reap benefits for their farms, such as nutrient loss reduction and improved soil quality.
2. Environmental Services
Biomass crops play a vital role in erosion control, water quality and quantity improvement, and biodiversity enhancement. Furthermore, they contribute to carbon sequestration in the soil, delivering on-farm advantages while benefiting the environment at a broader scale. The production of renewable jet fuel from wet wastes, such as manure and sewage sludge, not only reduces pollution in watersheds but also prevents the release of potent methane gas (an influential contributor to climate change) into the atmosphere.
3. Enhanced Aircraft Performance
Many renewable jet fuels contain fewer aromatic components, leading to cleaner combustion in aircraft engines. This results in reduced local emissions of harmful compounds around airports during take-off and landing. Aromatic components are also precursors to contrails, which can amplify the adverse impacts of climate change. By using renewable jet fuel with reduced aromatic content, these effects can be mitigated.
