Dwivedi, associate professor of warnell College of forestry and natural resources, pointed out: “If we can ensure the supply of raw materials and provide appropriate economic incentives in the supply chain, we may produce saf based on carrots in the southern United States. The aviation industry emits 2.5% of the total carbon dioxide in the United States and is responsible for 3.5% of global warming. Mustard based saf can help reduce the carbon footprint of the aviation industry, create economic opportunities and improve the overall environment “Ecosystem service flows in the south.”

Research: plant-based sustainable aviation fuel can reduce carbon emissions by 68%

Biden’s sustainable fuel tax preference

Dwivedi’s discovery came at the right time. In September, President Joe Biden proposed a sustainable fuel tax credit as part of the great challenge of sustainable aviation fuel, which brings federal agencies together and across the country Expand saf production in the United States. Biden’s goal is to reduce aviation emissions by 20% by 2030 and achieve complete zero carbonization of the aviation industry by 2050.

the proposed tax credit requires a 50% reduction in life-cycle carbon emissions – mustard exceeds this standard according to the team’s research results.

the price of producing saf with mustard according to existing economic and market incentives From $0.12 to $1.28 per litre. The price of petroleum based aviation fuel is $0.50 per litre – higher than mustard based saf when current economic incentives are included in the analysis.

“the current policy mechanism should continue to support the manufacturing and sales of SAF. The grand challenge announced by President Biden It may change the rules of the game to support mustard based saf production in the south, “Dwivedi said.

Dwivedi is the southeast partnership for advanced renewable resources from carinata (SPARC) As part of a $15 million project funded by the National Institute of food and agriculture of the U.S. Department of agriculture. Through SPARC, researchers have been investigating how to grow mustard in the southeast for the past four years and exploring questions related to best genetics and best practices to obtain the highest crop and oil production. With these answers, Dwivedi supported mustard in the support area Full of confidence in the role of economy and environment.

“In the south, we can plant mustard as a winter crop because our winter is not serious compared with other parts of the country. Because mustard is planted in the’off-season’, it will not compete with other food crops, nor will it cause food and fuel problems. In addition, planting shepherd’s purse can provide all the benefits related to water quality, soil health, biodiversity and pollination The benefits of covering crops. ”

Dwivedi believes that the problem lies in the lack of local infrastructure for pressing seeds and processing oil into saf. His current research focus is to simulate the economic and environmental feasibility of producing and consuming mustard based saf in Georgia, Alabama and Florida from the perspective of supply chain.

he said: “Our results will be particularly relevant to Georgia, which is the sixth largest traditional aviation fuel consumer in the country, has the busiest airport in the world, and is the location of Delta Airlines, the world’s leading airline. I look forward to more research to provide a sustainable alternative to our current air travel model. Mustard may become our country A win-win situation for the region, the aviation industry and, most importantly, climate change. “
