Multi-Objective Optimization for Sustainable Renewable Jet Fuel Production: A Case Study on Corn Stover Based Supply Chain System in Midwestern U.S
While the pursuit of a sustainable aviation industry is critical, it necessitates the optimization of the renewable jet fuel production supply chain. A case study in the Midwestern U.S. has revealed the intricate nature of establishing an efficient and sustainable supply chain for Sustainable Aviation Fuel (SAF) production, even for a corn stover-based system. The analysis delves into multiple aspects, including feedstock choice, preprocessing, logistics, and conversion procedures.
The potential for SAF production in the region spans across the Great Lakes to the Rocky Mountain regions. However, the current SAF production in the U.S. barely scratches the surface, accounting for less than 0.1 percent of total jet fuel consumed by major U.S. airlines. The ambition is to escalate this to 3 billion gallons per year by 2030, a near 20-fold increase.
The study also sheds light on the potential of alternative feedstocks such as isoprene from cyanobacteria, which can be transformed into hydrocarbons akin to existing aviation fuels using sunlight. Despite this, yields remain low. A techno-economic analysis of different pathways for SAF production also factors in, with Hydroprocessed Esters and Fatty Acids (HEFA) proving most competitive due to low conversion costs and high product yield.
Unifuel.tech presents a solution in the form of flexiforming, a technology that enables operators to control their decarbonization pace. Flexiforming can be implemented in an idle hydrotreater or reformer, which reduces capital expenditure and carbon intensity. By supplying details about feeds, target products, and existing facilities, Unifuel.tech can pinpoint an optimal application for flexiforming.
The aviation industry is responsible for 2% of global CO2 emissions. SAFs could play a pivotal role in achieving the sector's net-zero emission target by 2050. However, hurdles persist, including the high cost of SAFs, stringent carbon-emissions and land-use requirements, and the necessity for large-scale production.
Health Effects of Exposure to Jet Engine Emissions in and Around Airports
The environmental advantages of sustainable aviation fuel are well recognized, but it's also crucial to consider the health implications of jet engine emissions. These emissions, particularly nitrogen oxides (NOx) and fine particulate matter (PM2.5), are associated with several health issues, including cardiovascular, respiratory, and even psychiatric disorders.
A notable example is Dubai airport, which was found to be the world’s most polluting airport, contributing 20.1m tonnes of CO2 emissions, 7,531 tonnes of NOx and 71 tonnes of PM2.5 in a single year. Additionally, noise pollution from aircraft is a significant concern.
As the number of flights increase, so does the disturbance. This issue is especially significant near busy airports like Heathrow.
Residents under the flight paths experience a range of effects from exhaustion and stress-related symptoms to anger and displeasure. Recent research shows that noise pollution may increase the risk of cardiovascular diseases and other serious health problems, such as heart disease or diabetes, by disturbing sleep and causing stress. Furthermore, exposure to aircraft contaminated air and fume events has been linked to aircrew impairment and incapacitation, posing a risk to flight safety. This emphasizes the importance of sustainable aviation fuel in reducing harmful emissions and improving air quality in airport communities. Therefore, it's clear that the transition towards sustainable aviation fuel is not only an environmental imperative but also a public health necessity.
Biomass Feedstock Preprocessing and Long-Distance Transportation Logistics for Sustainable Aviation Fuel Production
The journey towards sustainable aviation fuel (SAF) production is intricately linked to the effective preprocessing and transportation of biomass feedstock. This is a vital step in securing a steady and cost-efficient supply chain for SAF production.
Biomass, waste materials, natural oils, fats, and other carbon sources form the core feedstocks for SAF, which is witnessing an upsurge of interest worldwide, particularly in Europe, the UK, and the USA. The global production of SAF is still limited despite ambitious adoption timelines and high volume targets.
This leads to a situation where demand surpasses supply. This scenario triggers significant concerns regarding the cost and sustainability of SAF, competition for feedstocks, and the economic efficiency of production scales.
A plausible solution can be found in the use of waste biomass through gasification and Fischer-Tropsch processes, a strategy adopted by companies like Velocys. This method proves cost-effective due to the low cost of waste biomass, such as forest residues, and the absence of shortage risk.
Additionally, this approach significantly cuts down carbon emissions. Australia is poised to become a significant player in the SAF industry, both as a source of feedstock and a producer of SAF.
The country is already a major exporter of feedstocks for biofuel production and has the potential to diversify its feedstock sources. Australia's growing hydrogen economy could provide a clean source of hydrogen necessary for various SAF production pathways. Incorporating innovative techniques such as the use of genetically modified photosynthetic microorganisms in SAF production, as investigated by research groups at Uppsala University, can optimize biomass feedstock quality, handling, and transportation. This, along with strategic logistics, can contribute to a sustainable and cost-effective supply chain for SAF production. Unifuel.tech offers a solution called flexiforming, which provides operators the flexibility to determine their decarbonization pace. Flexiforming can be integrated into an idle hydrotreater or reformer, thereby reducing capital expenditure and carbon intensity. This innovative approach by Unifuel.tech, a subsidiary of Universal Fuel Technologies, can potentially revolutionize the SAF production landscape, bringing us one step closer to a sustainable future.

Strategic Spatial and Temporal Design of Renewable Diesel and Biojet Fuel Supply Chains: Case Study of California, USA
The quest for efficient and sustainable production of renewable diesel and biojet fuel has led to strategic design considerations in supply chains. Fats, oils, or greases, as opposed to petroleum, are the preferred sources for renewable diesel, a fuel that is chemically similar to petroleum-based distillate.
This renewable diesel consumption trend, particularly on the U.S. West Coast, is projected to persist, with the possibility of completely phasing out petroleum diesel in California by 2030. Globally, the aviation sector relies heavily on sustainable aviation fuels (SAFs) to curtail emissions, especially for long-haul flights where other alternatives are not viable.
Although SAFs can be obtained from numerous feedstocks such as biomass, waste products, natural oils and fats, carbon sources, and hydrogen, their global production is limited. This has led to concerns about their affordability and sustainability as demand is predicted to outgrow supply.
In response to this, the petroleum industry is considering converting existing refineries to produce renewable diesel and SAFs, a move that could be more cost-effective than constructing new facilities. However, this is not a straightforward solution, as the business case for refinery conversions is complex and suitable only for a select few refineries.
In the UK, the focus is shifting towards building security and resilience in future fuel supplies, which could lead to different international dependencies compared to the current reliance on overseas crude oil and gas. Low carbon fuels offer potential advantages, especially when existing infrastructure can be repurposed for storage, distribution, and sale/supply.
Transitioning to refineries powered by renewables, however, is a significant challenge due to the continuous operation of refineries and the intermittent availability of renewable sources. Despite the enormous cost and scale of the transition, industry leaders and policymakers need to consider this vision seriously. In this scenario, technologies like flexiforming offered by Unifuel. Tech provide an attractive solution.
