“…Catalytic Hydrothermolysis, referred to as either CH-SK or CHJ, is the sixth fuel class which is derived from fatty acids and triglyceride-based feedstocks like soybean and tung oil. Extracted lipids are subjected to high pressures and temperatures through hydrothermal liquefaction followed by a final fractionation step (Eswaran et al, 2021). The final and most recent pathway, HC-HEFA, is similar to the process for developing HEFA but differs in that the hydrocarbon feedstock is specifically bio-derived from Botryococcus braunii, an oil-rich micro-algae (Goh et al, 2022).…”

This study outlines an effort to report on the physicochemical variability of Sustainable Aviation Fuels (SAF), leveraging data from the FAA Alternative Jet Fuels Test Database (AJFTD). The AJFTD, containing fuel sample records of conventional and sustainable aviation fuels to date, was developed by the PIs through the FAA Center of Excellence (ASCENT). With the development of SAF from various feedstocks and processing methods, new approval processes have been developed to accommodate the changing jet fuel landscape. To control for these differences, approval procedures were designed as each new fuel category came through the development pipeline. However, recent studies have suggested that rather than feedstock or processing method, chemical properties and fuel performance can be accurately judged by considering fuel composition characteristics such as carbon chain length, hydrocarbon class, and branching level. To quantify the variability present in recently approved jet fuels, this paper evaluates physicochemical property variability and provides relevant thermophysical property relations for conventional and alternative jet fuels with a discussion of efforts to streamline approval, reducing the time and cost of bringing new SAF to future markets. Findings from this study show that the variability in the composition and properties of SAF as compared to conventional fuels is small enough such that they still satisfy specification requirements outlined by the American Society for Testing and Materials (ASTM) D7566 standards for aviation fuels containing synthesized hydrocarbons.

A global shift toward sustainable manufacturing is underway, with companies and governments across the globe pledging to achieve net-zero carbon emissions by 2050. However, the path to net-zero is full of challenges, and without substantial changes to manufacturing practices, "net-zero" is unachievable. Biobased manufacturing could be a more sustainable alternative to traditional chemical production processes. We use triacetic acid lactone (TAL) produced from an engineered strain of Yarrowia lipolytica as a model system to explore the economic plausibility and environmental impact of several distinct routes to net-zero carbon emission manufacturing. Shifting away from conventional sugar-based fermentation, we employ a multiroute structure investigating alternative feedstocks including ethanol (2-ET), acetic acid (3-AA), and methanol (4-ME) as potential options for cost-effective and eco-friendly TAL production. Through comprehensive evaluation via bioprocess modeling, techno−economic analysis (TEA), and life cycle assessment (LCA), we evaluate the minimum selling price (MSP) and the intensity of GHG emissions for each production route and the environmental impact of raw material selection to gain clarity around net-zero emission strategies. The TEA shows that glucose-based TAL has the most favorable MSP of $28.60/kg at a production scale of 100 metric tons per year. In contrast, the MSPs of the TAL for scenarios 2-ET, 3-AA, and 4-ME are higher than glucose-based (1-GL) TAL. At 135 kiloton per year scale, acetic acid-based TAL, where the acetic acid was obtained from industrial off-gas fermentation, is the most cost-effective solution with an MSP of $6.06/kg. This strategy not only outcompetes the MSP of the glucose-based TAL by 8% but reaches net-negative CO 2 emissions. The study underscores the economic and environmental benefits of incorporating CO 2 utilization into manufacturing practices for net-zero production of TAL and other high-value compounds. Through the use of TAL as an example, this research showcases a cost-effective way to produce one bioproduct with net-zero greenhouse gas (GHG) emissions and also provides perspective on the economic outlook of bioproduction from substrates generated using carbon capture technologies when competing against traditional sugar-based fermentation.
