Sustainability is the driving force here - sources should be able to be repeatedly resourced. He explained: Airports will have to invest in infrastructure and will for sure pass that bill onto airlines, and they will pass it onto the customers, so it is all going to find its way. It's an alternative to fossil jet fuel (Jet A), which is made from crude oil also called liquid petroleum that is extracted from the ground. One of the main draws is that it can simply be added into the existing refueling framework, with no alterations needed to infrastructure or aircraft. Currently, most fuels use much lower proportions of SAF, but it is expected that this will increase over time. He explained: "Airports will have to invest in infrastructure and will for sure pass that bill onto airlines, and they will pass it onto the customers, so it is all going to find its way. It is 'heavier' than standard automotive gasoline, with longer strings of hydrocarbon atoms, and offers a higher flash point and lower freezing point. A concrete example is Neste, a Finish oil refining and marketing company, which has a contract with McDonalds to collect the used cooking oil from its Dutch restaurants. Sustainable Aviation Fuels (SAF) are an alternative. During the test flight, pilots perform a number of standard tests, as well as simulating exceptional circumstances, to ensure the fuel can withstand use under any operating conditions. Sustainable aviation fuel (SAF) - a low-carbon alternative to conventional, petroleum-based jet fuel - is helping the aviation industry lower its carbon footprint. In this process, purified liquids are exposed to a chemical reaction with hydrogen and catalysts and then distilled. But it is really about getting over the first hurdle as an industry, and then I think we'll see the SAF production evolve over the years ahead. In addition, biomass and municipal solid waste are expanding in use as sources. To reduce the growth of emissions associated with flying, airlines are looking to new types of liquid propellants called sustainable aviation fuels (SAFs). She is a reporter for Travel Tomorrow, and is also engaged in delivering communications services and EU policy research for different consultancies in Brussels. Power-to-liquid methods allow the production of synthetic kerosene, with the potential to reduce emissions by as much as 99%. Airlines such as United are making substantial investments in its development. They are based on renewable hydrocarbon sources that are not fossil fuel-based. For solid biomass, FT-SPK (FischerTropsch Synthetic Paraffinic Kerosene) is a leading process currently. Using SAF reduces carbon emissions over the lifecycle of the fuel as compared to the traditional jet fuel it replaces. Flight program marks first step in . She is also quite enthusiastic about space ventures and the cosmos. As part of IAG, Iberia Airlines is committed to achieving net-zero carbon emissions by 2050, with 10% implementation of sustainable aviation fuel (SAF) by 2030. "We've essentially electrified the fuel instead through our electrochemical process. By 2019, fossil jet fuel production cost was $0.3-0.6 per L given a $50-100 crude oil barrel, while aviation biofuel production cost was $0.7-1.6, needing a $110-260 crude oil barrel to break-even. More airlines are using Sustainable Aviation Fuel (SAF). The aviation industry is a leading contributor to excess CO 2 in our atmosphere. How sustainable aviation fuels can make our skies greener - and cleaner! Soon, sustainable biomass, such as forest trimmings and crop waste, will also be used to make SAF. Photo: Getty Images. Here's how SAF works: 1. But there is a lot of SAF that is going to be needed, and theres a big challenge ahead.. Neste is ready to play its part to support the Canadian industry's aspirational goal of 10% SAF use by 2030." Sustainable aviation fuels must have the same qualities and . How Are Sustainable Aviation Fuels Made? While SAF production volumes remain low, a blend limit does not hamper the use of SAF, however, it is expected that the blend limit will eventually increase to 100%. There are many initiatives underway to make aviation greener and lower overall emissions. In this process, purified liquids are exposed to a chemical reaction with hydrogen and catalysts and then distilled. For FOGs, the most widespread is HEFA (Hydrotreated Esters and Fatty Acids). There is a long way to go for major adoption of this, but it could deliver a carbon-neutral circular system for aviation, using the carbon dioxide that aviation is responsible for and turning it back into power for the planes. But with a lower energy density, more feedstock volume is needed. A former Blue Book trainee of the European Commission, Marta has a keen interest in EU and global affairs, and experience in reporting and interpreting information. Aviation is a big user of fossil fuels and, as such, is a heavy producer of carbon emissions. The Biden administration announced the SAF Grand Challenge last fall, outlining a commitment to work with industry to produce 35 billion gallons of sustainable aviation fuel per year by 2050, meeting 100 percent of U.S. aviation fuel needs. These topics include the following: Sustainable Aviation Fuel (SAF): kids learn about the impact of today's jet fuel on the environment. Once the lab and ground testing have been completed, the fuel is tested on aircraft under normal operating conditions. Add me to Travel Tomorrow's mailing list. The expected value of the agreement is estimated to be somewhere in . Each of the four episodes explains a key topic and inspires kids to think critically about them. 3. The process consists of exposing purified liquids to a chemical reaction with hydrogen and catalysts for further distillation. SAF is created from environmentally friendly materials and may be blended with any type of fossil jet fuel to cut emissions. Airbus has the ambition to reduce its industrial emissions by up to 63% by 2030 and is using sustainable aviation fuels as a catalyst toward this goal. 2. In this way, cross-sector collaboration helps create targeted solutions for overcoming the biggest barriers to realize low- or net-zero-carbon aviation. Cost is a major factor here this should reduce as collection and production availability expands. He sees production and cost as major hurdles to get over as SAF use is scaled. Sustainable aviation fuel is a key player. Some emerging SAF pathways even have a net-negative GHG footprint. One or multiple sources can compose the feedstock that produces SAF waste products, such as vegetable oils or household waste, or specifically grown plant material. Or even from carbon captured from the air and green hydrogen. Carbon transformation company Twelve announced Tuesday it had produced its first batch of E-Jet fuel in collaboration with the US Air Force. Neste, for example, has a contract with McDonalds to use cooking oil from its Dutch restaurants. Carbon transformation company Twelve is now producing jet fuel from CO2 electrolysis.

Longer-term, though, it should offer more stable pricing than oil and will become ever more important as the industry works towards its target of halving overall emissions by 2025 (based on 2005 levels). The carbon in Twelve's E-Jet fuel comes from direct air capturerather than from CO2 stored in the ground. This means that Sustainable Aviation Fuel (SAF) provides the only viable way to reduce aviation emissions significantly in the short to medium-term. Sustainable aviation fuel is the solution found by the aviation industry to the current environmental situation. More airlines are using Sustainable Aviation Fuel (SAF). SAF is produced by converting readily available materials into a drop-in replacement crude oil. Journalist - With almost a decade of experience in the publishing sphere, Justin has built up a deep understanding of the issues facing aviation today. They are based on renewable hydrocarbon sources that are not fossil fuel-based. Airbus is reducing its CO 2 footprint with Sustainable Aviation Fuels. Once collected and separated, these feedstocks are then refined to produce fuel. Discussions are moderated for civility. Tests look at specific fuel consumption at several power settings, from ground idle to take-off speed, which is then compared to performance with conventional jet fuel. This involves the gasification of solid biomass at a high temperature, producing a synthesis gas that is further converted into hydrocarbon chains. Twelve and Emerging Fuel Technologies have not made their specific proprietary catalyst public. Sustainable Aviation Fuel (SAF) is made from more sustainable resources. According to Neste, SAF could reduce greenhouse gas emissions by up to 80% compared to normal fossil jet fuels. Photo: Getty Images, With the situation so unpredictable, airlines are having to prepare for surprises. Lead Sustainability Journalist - With a Masters in International Relations, Linnea has combined her love for current affairs with her passion for travel to become a key member of the Simple Flying team. For FOGs, the most widespread is HEFA (Hydrotreated Esters and Fatty Acids). He sees production and cost as major hurdles to get over as SAF use is scaled. Sustainable aviation fuel costs lowered by the new framework. 2022 was a landmark year for sustainable aviation fuel (SAF), with a greater number of SAF offtake agreements announced (as well as a higher volume of fuel) than in the previous two years combined - and by far, the most of any year to date. SAF is blended with traditional fuel in ratios up to 50%. The SAF available today is considered "drop-in" because it meets the same characteristics of Jet A. But with a lower energy density, more feedstock volume is needed. With a keen interest in route development, new aircraft, and loyalty, his extensive travels with airlines such as British Airways and Cathay Pacific has given him profound direct comprehension of industry matters. For the time being, fats, oils and greases are the major sources of SAF. Although some airlines have made high profile commitments to its use, overall adoption remains low compared to traditional jet fuel. Regular jet fuel is a high-density kerosene-based fuel. Firstly, a quick recap on standard jet fuel is helpful. SAF can be made from renewable sources such as used cooking oil, municipal waste and woody biomass. Approval for additional production processes is expected in the coming years. Since you can't electrify the plane, we've electrified the fuel," Mr Flanders continued. Sustainable aviation fuel is airplane fuel made from biomass materials. Once collected and separated, these feedstocks are then refined to produce fuel. Today, many airlines have made commitments to certain levels of SAF use, and this is expanding. There is an ongoing fuel shortage worldwide. There's lots of talk about SAF, but will it go far enough? They are based on renewable hydrocarbon sources that are not fossil fuel-based. It is heavier than standard automotive gasoline, with longer strings of hydrocarbon atoms, and offers a higher flash point and lower freezing point. SAF is not used directly as a fuel but it can be used in existing jet engines after mixing with traditional jet fuel. SAF is perhaps best . Critically, this means that (post-blending) no changes are needed to existing fuel infrastructure in the supply chain and at airports. This landscape should reduce as collection and production availability expands. And, the Challenge calls for a near term goal to produce at least three billion gallons of sustainable . Cellulosic - These are the residues from excess wood, agriculture, and forest residues. This means they can be used in a standard jetliner with little or no modification required. The blending process guarantees a similar performance and handling characteristics. More specifically, Iberia plans to purchase 6 million gallons of sustainable aviation fuel per year over the span of 5 years. Directly turning CO 2 from the atmosphere into sustainable aviation fuel, AIRMADE SAF addresses our planet's biggest problem head on.. Compared to petroleum jet fuel, SAF produced from today's corn ethanol also already offers a 15 percent lower carbon intensity. Whenever she can, Marta loves traveling, exploring nature and learning about regenerative agriculture. In line with its purpose to pioneer sustainable aerospace for a safe and united world, Airbus is working to reduce the environmental footprint of its products and services. Based in Amsterdam, Netherlands. Embraers CEO, Arjan Meijer, spoke to Simple Flying about these challenges. Sustainable Aviation Fuel (SAF) is made from renewable resources and has a chemistry that is remarkably comparable to standard fossil jet fuel. This has been developed to offer the high power needed for aircraft engines. The table below shows the seven different internationally approved processes through which sustainable aviation fuel (SAF) can currently be made. Based in Hong Kong and Darlington, UK. SAF Sustainable Aviation fuel is a green fuel made of biomass and waste. This ensures similar performance and handling characteristics. Critically, this means that (post-blending) no changes are needed to existing fuel infrastructure in the supply chain and at airports. More and more airlines are betting on sustainable aviation fuel (SAF) to make aviation greener. SAF stands for sustainable aviation fuel. 4. Currently, fats, oils, and greases (FOGs) are a leading source. Sustainable Aviation Fuel (SAF), a biofuel having qualities similar to those of regular jet fuel but a lower carbon footprint, is used to power aeroplanes. sulphur) allow seals to swell in engines and prevent fuel leaks. Walsh noted that consumers will be willing to pay the extra costs associated with its uptake. Love aviation? Meanwhile, Executive Vice President Renewable Aviation at Neste Thorsten Lange said, "Sustainable aviation fuel is the fastest, most effective means we have to reduce the greenhouse gas emissions from air travel. Sustainability is the driving force here sources should be able to be repeatedly resourced. Twelve says that its E-Jet fuel emits 90% less CO2 over its lifecycle compared to fossil-based fuel. To ensure technical and safety compliance, SAF must undergo strict laboratory, ground, and flight tests under an internationally-recognised standard. At present, SAF must be blended with conventional jet fuel (up to 50%). Producing ethanol from corn is a mature technology, and life-cycle GHG emissions of corn ethanol have decreased by roughly a quarter in the past 15 years, excluding land-use change emissions. What do you think of the new fuel technology? How does SAF work? Several. These have the potential to reduce overall greenhouse gas emissions even further (85% to 95% over their lifecycle compared to traditional fossil-based jet fuel). However, the fuel is certified and ready to go - and available for order via the company's website. It's produced from sustainable feedstocks and is very similar in its chemistry to traditional fossil jet fuel. The blending process requires strict safety measures and requirements. The lower-point is that these sources have a lower energy density and require larger volumes of feedstock. Power-to-liquid methods allow the production of synthetic kerosene, with the potential to reduce emissions by as much as 99%. Blended SAF is Delivered to the Airport. Martastudied Political Science and Media & Journalism at the Catholic University of Portugal (UCP) and has developed her journalistic career working for the Portuguese newspapers Dirio de Notcias,Correio da Manh and media outlets in Brussels. The technology to turn carbon dioxide into fuel came into focus late last year when researchers at Oxford University in the UK successfully converted CO2 gas directly into jet fuel. Therein lies the problem, but also the solution. Currently, aviation is responsible for at least 12% of global Co2 emissions. Without getting into too much detail, the technology entails that by combining electrolysis with low-carbon energy sources, water and CO2 are converted into a feedstock with a minimal carbon footprint. It consists of the gasification of solid biomass at high temperatures, producing a synthesis gas that is converted into hydrocarbon chains. Sustainable Aviation Fuel (SAF) is considered the most important way to decarbonise airline operations in the next few decades, before alternatively powered aircraft can be widely deployed in . Using SAF results in a reduction in carbon emissions compared to the traditional jet fuel it replaces over the lifecycle of the fuel. It's generally fuel derived from renewable biomass or sustainable feedstock There's a range of different biomasses and feedstock types that can be used to make the fuel It involves biomass or feedstock being sourced, and then converted into fuel With a promise of up to 80% fewer emissions compared to petrochemical-based fuels, it is easy to see why IATA believes the proliferation of SAF will accomplish as much as 65% of its net-zero by 2050 target. These have the potential to reduce overall greenhouse gas emissions even further (85% to 95% over their lifecycle compared to traditional fossil-based jet fuel). Biomass and municipal solid waste (MSW) are expanding in use as sources. Sustainable aviation fuel (SAF) is a term used to describe alternative aviation fuels made from sustainable and renewable sources. Would you like to discuss the current or future production and use of SAF? The fuel is achieved through CO2 electrolysis and introduces a scaleable fossil-free drop-in alternative with up to 90% fewer emissions throughout its lifecycle . These have the potential to reduce greenhouse gas emissions by 85% to 95% over their lifecycle compared to traditional fossil-based jet fuel. Find out more about the sustainability background of SAF and view the Beginner's Guide to Sustainable Aviation Fuel. Also for the backroom boys and girls who support the flying and maintain the equipment, and without whom nothing would ever leave the ground. Today, many airlines have made commitments to certain levels of SAF use, and this is expanding. Sustainable Aviation Fuel (SAF), is jet fuel made from renewable materials, such as waste biomass or food scraps. Postdoc position "Prospect for CO2-made sustainable aviation fuel in the United States of America" Long-haul aviation will depend on the availability of hydrocarbon-based fuels for the . In 2019, 13 million gallons (50 million litres) of SAFs were used in flights, just 0.01% of global aviation fuel, meaning the industry missed a goal set in 2010 to reach 6% use by 2020. SAF was first used in 2008 (according to Shell). We take a look here at how SAF is produced and used in aircraft engines. Combined fuel must meet strict requirements. Depending on the feedstock and technologies used to produce it, SAF can reduce life cycle GHG emissions dramatically compared to conventional jet fuel. And that is the primary purpose of sustainable aviation fuel. The resulting fuel is re-certified as Jet A or Jet A-1 fuel and can then be handled, transported and used in the same way as traditional fuel. SAFs are already available and compatible with existing carriers; however, the SAF, which is often made from agricultural and commercial waste is up to 40 times more expensive than existing jet fuel refined from crude oil. The fuel is achieved through CO2 electrolysis and introduces a scaleable fossil-free drop-in alternative with up to 90% fewer emissions throughout its lifecycle compared to conventional jet fuel. Our SAF Efforts The amount of SAF produced in 2021 met only 0.1% of global jet fuel demand. There is a long way to go for major adoption of this, but it could deliver a carbon-neutral circular system for aviation, using the carbon dioxide that aviation is responsible for and turning it back into power for the planes. Military Aviation A forum for the professionals who fly military hardware. Sustainable Aviation Fuels (SAFa) are aviation fuels that are produced largely from renewable bio-feedstocks (think corn, rapeseed, or palm oil) or waste from other production processes (used cooking oils, food waste, or other bio-based solid waste). Through testing in laboratories, in equipment on the ground, and under the extreme conditions of in-flight operations, an exhaustive process determines the suitability of SAF. Twelve is targeting production in the millions of gallons within the next two years and in the billions of gallons within the next decade. Sustainable Aviation Fuel (SAF) is an aviation fuel made from sustainable and renewable sources which can act as a substitute for fossil jet fuel. SAF was first used in 2008 (according to Shell).
