“…Production of carinata as a winter crop presents a unique opportunity for growers in the Southeast United States to produce a significant amount of biofuel feedstock to contribute to domestic energy needs. Carinata fits into existing cropping systems as a winter crop, providing opportunities to farm over 1.4 million hectares of winter fallow land that could translate to over 1224 million liters of jet fuel, displacing 1.4%–2.33% of petroleum‐based jet fuel in the United States (Alam & Dwivedi, 2019).…”

“…It is important to emphasize that these crops could be produced as a second crop on the existing croplands that remain fallow in winter otherwise. While these oilseed cover crops can be used for biodiesel production, many papers have addressed the use of these oilseed cover crops to produce aviation biofuels (Zanetti et al, 2019;Alam and Dwivedi, 2019;Trejo-Pech et al, 2019;Robertson, 2020). Currently, the aviation industry relies on fossil fuels with no other economically affordable fuel alternatives (Prussi et al, 2021).…”

Oilseed Cover Crops for Sustainable Aviation Fuels Production and Reduction in Greenhouse Gas Emissions Through Land Use Savings

2022

Induced Land Use Changes (ILUCs) can decrease the environmental benefits of Sustainable Aviation Fuels (SAFs) if produced from traditional food crops. The development of oilseed cover crops can eliminate the side effect of ILUCs for biofuel production because they come in rotation with the major crops with some savings in demand for new cropland. This study implemented Life Cycle Analysis (LCA) and GTAP-BIO to estimate ILUC emissions values, the potentially available area, and total possible emissions savings of producing SAFs from carinata, camelina, and pennycress in the United States. The results suggest that: 1) the meals produced in conjunction with increases in Sustainable Aviation Fuel production from carinata, camelina, and pennycress could reduce land use emissions by 12.9, 15.3, and 18.3 gCO2e/MJ, respectively; 2) the total area of available land for producing these feedstocks could be about 29.3 million ha in 2035; and 3) using this area of land for SAF production, depends on the mix of oilseed cover crops that can be produced in practice, could generate up to 92 million metric tons of savings in GHG emissions per year. The projected emissions savings is about 11% of the current global GHG emissions generated by the aviation industry. Providing incentives to encourage farmers to produce these cover crops and facilitating investment in producing SAF from these cover crops are the most important factors that could help the aviation industry to enhance emissions savings.

“…It was introduced in the Southeastern United States in 2010 through a joint research collaboration between the University of Florida Institute of Food and Agricultural Sciences (UF‐IFAS) and Nuseed (Nuseed, 2020). About 1.4 million hectares of land were found suitable for carinata production in the Southeastern United States (Alam & Dwivedi, 2019). Carinata could be easily integrated into the current cropping systems in the Southeastern United States, as it grows well in winter months when agricultural land remains unused and, therefore, provides much‐needed cover to otherwise exposed soils and reduces soil erosion (Seepaul et al, 2021; Seepaul et al, 2020).…”

The production of biomass‐based sustainable aviation fuel (SAF) is gaining traction to reduce the carbon footprint of the aviation sector. We performed a techno‐economic analysis to estimate the break‐even price and life cycle carbon emissions of the SAF derived from carinata (Brassica carinata) in the Southeastern United States. Carinata has the potential as a feedstock for SAF production in the selected region due to higher yield, low fertilizer use, co‐product generation (animal feed, propane, and naphtha), and compatibility with current farming practices. The system boundary started at the farm and ended when the SAF is delivered to an airport. Without co‐product credit or other subsidies such as Renewable Identification Number (RIN) credit, carinata‐based SAF was more expensive ($0.85 L−1 to $1.28 L−1) than conventional aviation fuel ($0.50 L−1). With co‐product credit only, the break‐even price ranged from $0.34 L−1 to $0.89 L−1. With both co‐product and RIN credits, the price ranged from ‐$0.12 to ‐$0.66 L−1. The total carbon emission was 918.67 g CO2e L−1 of carinata‐based SAF. This estimate provides 65% relative carbon savings compared with conventional aviation fuel (2618 g CO2e L−1). Sensitivity analysis suggested a 95% probability that relative carbon savings can range from 61% to 68%. Our study indicates that carinata‐based aviation fuel could significantly reduce carbon emissions of the aviation sector. However, current policy support mechanisms should be continued to support manufacturing and distribution in the Southeastern United States.
