SAF is perhaps best . 7 technical pathways exist. When flying on SAF, the climate impacts are significantly lower but not entirely reduced to zero. In the future, we maybe be able to rely on SAFs as a driver of carbon neutral air transport. Other, more advanced, technologies are in early stages of development, such as solar jet fuel (or sun-to-liquid), which uses highly concentrated sunlight to break up water and CO2 molecules. There are major concerns in some quarters that an increased uptake of SAF could, among other things, result in significant deforestation and create a squeeze on crops crucial to the production of food. The primary market for camelina oil is as a feedstock to produce renewable fuels. Using organic municipal solid waste as a feedstock for SAF also recycles carbon contained in the waste and reduces methane emissions, a potent greenhouse gas that can leak from landfills. Many airlines have shown real leadership in advancing the production and deployment of SAFs and have participated in its development from the outset. RD benefits from favorable tax policy, making its production more profitable; it dwarfs SAF output nationally. Sustainable aviation fuel provides a cleaner alternative to fossil fuel, achieving up to an 80 percent reduction in greenhouse gas emissions over the fuel's lifecycle, compared to conventional fossil jet fuel. EESI advances science-based solutions for climate change, Some of our partners may process your data as a part of their legitimate business interest without asking for consent. [SAF was about] two and a half times the price of jet kerosene [in 2022] When you factor in the cost of carbon, youre looking at maybe twice the price of kerosene, Sustainable fuels are about twice what youre paying for the traditional jet kerosene, so it does represent a significant hike in the airline industrys cost base. "Sustainable fuels are about twice what you're paying for the traditional jet kerosene, so it does represent a significant hike in the airline industry's cost base," he said. This isn't any different for any other facility if you think about the petroleum refinery industry, we face a lot less challenging than that industry, but it's still a new refinery so that that's a complex process.. Biofuels generally refer to fuels produced from biological resources (plant or animal material), and their production isnt always sustainable. We and our partners use cookies to Store and/or access information on a device. Municipal solid waste: waste that comes from households and businesses. The goal that the airline industry has set for itself is two billion gallons of SAF by 2030. SAFs are different to standard biofuels. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'bettermeetsreality_com-narrow-sky-2','ezslot_16',126,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-narrow-sky-2-0'); According to bp.com the aviation industry [is] expected to double to over 8 billion passengers by 2050. Sustainable aviation fuels (SAF) are attractive to the aviation industry because they provide a large reduction of greenhouse gas emissions with little changes to current technology. Some reports indicate sustainable aviation fuel may only help significantly lower the carbon footprint of medium to long haul flights. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'bettermeetsreality_com-netboard-2','ezslot_18',135,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-netboard-2-0'); Many Airlines Have Already Used It, & Some Level Of Future Use/Demand Is Already Guaranteed, [The first test flights using blended bio fuel were in 2008, and 2011 saw 50% blended biofuels used for commercial flights] (wikipedia.org), Airlines & Locations That Have Experience Using SAF, iata.org indicates that over 45 airlines now have experience with sustainable aviation fuel, and theres already forward purchase agreements locked in for its future use, bp.com indicates that Air bp has supplied SAF at over 20 locations across three continents, Pre-Orders Of SAF For Use In The Future, cnbc.com indicates that airlines had ordered 14 billion liters of SAF, bp.com mentions that Any aircraft certified for using the current specification of jet fuel can use SAF and also mention that they have supplied SAF to a range of aircrafts from small private jets to large passenger aircrafts, Its worth noting that SAF used in aircrafts should be quality tested and certified, There Are Reasonable Feedstock Supplies Available To Make Biofuels In The US, energy.gov indicates An estimated1 billion dry tons of biomass can be collected sustainably each year in the United States, enough to produce 5060 billion gallons of low-carbon biofuels, May Create New Economic Opportunities & Jobs. SAF currently costs four times as much as conventional jet fuel and it makes up less than one percent of fuel available in the market. CO2 absorbed by plants during the growth of biomass is roughly equivalent to the amount of carbon dioxide produced when the fuel is burned in a combustion engine, which is simply returned to the atmosphere, meaning SAFs can be classed as carbon neutral over their lifecycle. However, further production facilities are being constructed or planned, and a number of leading airlines are signing significant forward purchase agreements which help provide offtake certainty to new energy suppliers, allowing them to finance new plants. As the technology matures it will become more efficient and so the expectation is that it will become less costly for customers. Neste has been able to convert some of its conventional refineries to process SAF. Still Uses Conventional Jet Fuel In The Final Fuel Product, Several SAF products dont use 100% sustainable aviation fuel they are blended with conventional jet fuel, bp.com indicates that SAF can be blended at up to 50% with traditional jet fuel, Although there might still be a reduction in carbon emissions with blended fuels, they still partially use petroleum based fuels (with hydrocarbons in them) in the final product when they use conventional jet fuel, Some of the reasons fuels might be blended might include for efficiency, performance, and cost, and other reasons, Conventional jet fuel is energy dense for its weight for example, The Scale Of Use Of Sustainable Aviation Fuel Is Not Yet Where Conventional Jet Fuel Is, & There Might Be Barriers To Growth. SAF also generates fewer conventional pollutants that contribute to local air quality concerns around airports. A diverse set of feedstocks is required for a shift from conventional jet fuel. Algae: these microscopic plants can be grown in polluted or salt water, deserts and other inhospitable places. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[336,280],'bettermeetsreality_com-box-4','ezslot_2',114,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-box-4-0'); Its generally fuel derived from renewable biomass or sustainable feedstock, Theres a range of different biomasses and feedstock types that can be used to make the fuel, if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[336,280],'bettermeetsreality_com-banner-1','ezslot_4',118,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-banner-1-0');It involves biomass or feedstock being sourced, and then converted into fuel, Some sustainable aviation fuels are blended in different % shares with conventional jet fuel in the final fuel product (currently up to 50% of each type of fuel according to several reports, although higher % share sustainable aviation fuel shares might be possible in the fuel). Got a confidential news tip? Having said this, popsci.com mentions that other solutions like electric aircrafts and hydrogen powered planes may have limitations such as shorter flight ranges, being smaller in size than traditional planes, and in the case of hydrogen powered planes, being a while off of commercialization and scaling.

All electric- or hydrogen-powered flight for large aircraft and long distances could be decades away. Read all of the articles in the Sustainable Aviation Fuel series. With "appropriate government policy support," IATA says it expects to see SAF production hit 7.9 billion liters by 2025, which would meet just 2% of the overall fuel requirement. The development of alternative aviation fuels could be the key to sustainable air travel, contributing hugely to the industry's emissions-reduction strategy. We'll deliver a dose of the latest in environmental policy and climate change solutions straight to your inbox every 2 weeks! Hydroprocessed Esters and Fatty Acids (HEFA-SPK) made from oil-bearing biomass, such as algae, jatropha and camelina. With fewer particulates in aircraft exhaust, contrail formation is diminished. 1020 19th Street, NW, Suite 400 The blending limit is up to 10%. For example, using the waste gases produced as a by-product in steel manufacturing to produce sustainable aviation fuel is showing great promise. This fuel can be sustainable if the inputs are recovered as by-products of manufacturing already taking place, and/or if renewable electric energy is used in its production. One innovation is sustainable aviation fuels, which are jet fuels created from waste products and other sustainable feedstocks that have the potential to reduce emissions by 80%. Although there's no one agreed upon definition of SAF, the main sustainability feature of SAF according to several reports is that it reduces . Sustainable aviation fuel plays a very important role in that, it's not the only technology that's working to decarbonize aviation, but it is a critical technology.. Nor does it take into account SAFs made from non-biological sources, such as municipal waste. This depends on the feedstock and processes used though, and whether they truly are more sustainable or renewable, or are just marketed that wayif(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'bettermeetsreality_com-narrow-sky-1','ezslot_15',132,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-narrow-sky-1-0'); wikipedia.org indicates that Biofuels do not contain sulfur compounds and thus do not emitsulfur dioxide, Depending on the location though, sulfur dioxide emissions may or may not be a significant issue, energy.gov indicates that biomass crops may help control erosion, improve water quality and quantity, increase biodiversity, store carbon, and reduce pollution pressure of watersheds. There are currently seven SAF production processes (pathways) approved as safe for use in blended form by civilian jet aircraft. In the United States, there were just over 4.5 million gallons of SAF produced in 2020, a substantial increase over 2019, but only a small fraction of the 18.3 billion gallons of jet fuel consumed in 2019 by scheduled U.S. carriers. Environmental impact is not the only impact that has to be considered economic, practical, social and other impacts have to be considered too. The only difference is that the feedstock is from non-fossil sources.. SAF made from plant feedstock limits the introduction of carbon into the atmosphere because plants absorb CO2 through photosynthesis during growth. Paul Stein, chief technology officer at Rolls-Royce PLC, compared the need for the development of SAF to the current COVID-19 vaccination production during a panel discussion at the remotely hosted Farnborough International Airshow Connect on July 14. Right now, the cost of sustainable aviation fuel on its own without any incentives, if you will, would cost maybe four or five times that of existing petroleum fuels and that's not sustainable for the industry, Valerie Reed, the acting director of the bioenergy technologies office at the Department of Energys Office of energy efficiency and renewable energy, told, Paul Stein, chief technology officer at Rolls-Royce PLC, compared the need for the development of SAF to the current COVID-19 vaccination production during a panel discussion at the remotely hosted, Farnborough International Airshow Connect on July 14. in Congress that could provide a similar blenders tax credit for SAF nationwide. Camelina: an energy crop, with high lipid oil content. For example, growing dedicated biofuel crops, or harvesting biomass feedstock may present new economic opportunities to farmers and other producers. "I think that addresses the issue of whether airlines will buy the product," he said. Long term, consumers would recognize this would be the case. With the global growth in air travel, the aviation industry is investing in alternatives to fossil jet fuels to reduce flight emissions. Catalytic hydrothermolysis synthetic jet fuel (CHJ) made from triglyceride-based feedstocks such as plant oils, waste oils, algal oils, soybean oil, jatropha oil, camelina oil, carinata oil and tung oil. This guide compliments our separate guide on whether sustainable air travel is possible. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'bettermeetsreality_com-mobile-leaderboard-2','ezslot_14',125,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-mobile-leaderboard-2-0'); popsci.com indicates that [most SAFs are] two to four times as expensive as traditional jet fuel, and its not likely SAFs will ever be as cheap as fossil fuels are even though prices can likely come down a bit when technology scales and becomes more common. All airplane fuel products (and there are a range of different ones) have different variables involved in their lifecycle, and this impacts their sustainability and how they affect the environment. It can also provide up to an 80 percent reduction in emissions compared to jet fuel. Air bp is working on helping create more demand in the short-term which will lead to more production and hopefully lower costs in future, cnbc.com indicates that SAF is currently more expensive than traditional jet fuel, Consumers Will Likely Bear The Increased Cost For Sustainable Aviation Fuel. Camelina is often grown as a fast-growing rotational crop with wheat and other cereal crops within the same year, when the land would otherwise be left fallow as part of the normal crop rotation programme. Used cooking oil: this typically comes from plant or animal fat that has been used for cooking and is no longer usable. There are currently eight different pathways certified to produce SAF. The chemical and physical characteristics of sustainable aviation fuels are almost identical to those of conventional jet fuel, meaning the two can be safely blended together. Our work is licensed under a Creative Commons Attribution License. Biomass based fuels absorb carbon during product, but release that carbon when they are burnt. Sustainable aviation fuel's main challenge relates to volume rather than airlines' desire to use it, and consumers will be willing to pay the extra costs associated with its uptake, the director general of the International Air Transport Association told CNBC Friday. "I think quantity is the main issue at the moment," Willie Walsh, who was speaking to "Squawk Box Europe" on Friday morning, said. More than one billion dry tons of biomass is potentially available annually in the coterminous United States as feedstock for bioenergy and chemical products, enough to exceed projected U.S. domestic aviation fuel demand. Tests are also carried out to ensure that the fuels dont have a negative impact on the materials used in building aircraft and components. bp.com indicates that SAF gives [a] reduction of up to 80% in carbon emissions over the lifecycle of the fuel compared to traditional jet fuel it replaces, depending on the sustainable feedstock used, production method and the supply chain to the airport. SAFs are made using a variety of feedstocks and waste products. Along with future hybrid, electric or hydrogen-powered aircraft, Sustainable Aviation Fuels (SAF) represent one of the most promising solutions for aviation as the sector looks to transform itself towards a more sustainable future. We need to build capacity and that takes time, Plaza said. Our SAF is produced from sustainable feedstock waste residues such as used cooking oil and animal fat, and then actually goes through a very, very involved process of getting it processed and certified, Chandhoke said. Airplane fuel has to be sourced from a feedstock, then refined and processed/converted into fuel, then made into a useable fuel product (blended or not blended), then burnt/used on aircrafts. Tax is not the Answer to Aviation Sustainability, IATA supports incentives for Sustainable Aviation Fuels (SAF) and modernization of air The blending limit is 50%. These residues can be processed into synthetic fuel. In order to be sustainable, feedstocks cant compete with land use or food production, and existing critical forests and rainforests cant be cut down to supply feedstock. The environmental footprint of aviation is considerable, with the World Wildlife Fund describing air travel as "currently the most carbon intensive activity an individual can make. Another type of sustainable jet fuel is e-SAF or Power to Liquid (PtL). Sign up for free newsletters and get more CNBC delivered to your inbox. Fischer-Tropsch Synthetic Paraffinic Kerosene with aromatics (FT-SPK/A) made from renewable biomass such as municipal solid waste, agricultural wastes and forestry residues, wood and energy crops. May Help Extend The Useful Lifespan Of Older Aircrafts. For this reason, SAFs are known as drop-in fuels because they can be used without any technical modifications to existing aircraft, engines or airport fuel systems. Published Jul 16, 2021. Well, like any industrial fuel refining facility, there's the need to find the right location to build it, the feedstocks need to be secured, the engineering and permitting process can be arduous and lengthy, Plaza said. Crop based biofuels that contribute to deforestation and dont use renewable energy could have higher CO2 emissions. Over 450,000 flights have taken to the skies using SAF. However, given the current lack of supply and infrastructure, they are still prohibitively expensive for ULCCs such as Wizz Air. A big one, is sustainable aviation fuels, Minicucci said. Other solutions like more efficient fuel use per passenger may be potential solutions too. Each seed produces 30 to 40% of its mass in oil. 2022 CNBC LLC. (Neste). Other solutions have to be pursued alongside SAF. Sustainable aviation fuel's main challenge relates to volume rather than airlines' desire to use it, and consumers will be willing to pay the extra costs associated with its uptake, the . Because of these benefits, many companies have cited SAF as a major part of their strategy to get to net-zero emissions. In the guide below, we discuss sustainable aviation fuel. One innovation is sustainable aviation fuels, which are jet fuels created from waste products and other sustainable feedstocks that have the potential to reduce emissions by 80%. Rather than simply dumping municipal waste in a landfill site, where it will gradually emit CO2 and other gases, it can be used to create jet fuel instead. SAF is a drop . "This is such an important issue. Yet new fuels have been developed that have the potential to dramatically reduce aviations net CO2 emissions. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'bettermeetsreality_com-portrait-2','ezslot_20',134,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-portrait-2-0'); Biofuels can be blended in different % shares with conventional aviation fuel after sustainable feedstock has been sourced, and converted to SAF, This allows some flexibility in getting the desired balance of fuels in the final fuel product, Might Use Some Existing Fuel Infrastructure & Aircrafts, Aside from the feedstock, biorefineries and conversion of feedstock into fuel, blended SAF might make use of some of the same infrastructure and aircrafts as traditional jet fuel according to some reports. increase or improve, but, other reports say it may never be as cheap as kerosene based jet fuel, bp.com goes as far as to indicate that higher costs might be limiting wide uptake right now: At the moment, production of SAF is limited as the higher cost for SAF is preventing wider uptake. When blended with 50 percent conventional fuel, the reduction in CO2 emissions is still a substantial 40 percent. For example, some biofuels, if produced from non-sustainable feedstocks, like unsustainably-produced palm oil or crops that require deforestation, can cause additional environmental damage. Relative to fossil fuels, SAFs result in a reduction in CO2 emissions across their lifecycle. There is a lot of work being done with the government on a SAF blender's tax benefit and there's a lot being done with industry to increase the amount of sustainable aviation fuel. On the other hand though, wikipedia.org mentions that fuel oil extraction from algae between 2005 to 2012 did not produce any significant results, despite dozens of companies receiving hundreds of millions of dollars in venture capital. The strategy with the most promise for substantially reducing the sectors carbon footprint in the near and medium term is expanding the use of sustainable aviation fuel (SAF). SAF made from renewable biomass and waste resources have the . ". When you factor in the cost of carbon, you're looking at maybe twice the price of kerosene.". Data is a real-time snapshot *Data is delayed at least 15 minutes. Aviation is steadily growing worldwide as well as in the European Union (EU).

Shifting to H2 as a fuel source presents a significant set of challenges in production, storage and infrastructure, aircraft configuration and engine modification requirements. However, continued R&D may result in wider application in the future. In terms of content, aircraft maker Airbus has described sustainable aviation fuels as being "made from renewable raw material." We want to hear from you. According to the ATAG report, growing non-food plant feedstocks for SAF has the potential to use otherwise unproductive land, provide employment opportunities in rural areas, add revenue for farmers, and can enrich soil when feedstocks are grown as cover crops in between growing seasons for conventional crops. To date, we have not seen algae fulfil its early promise due to challenges surrounding commercialisation. When you book a flight at KLM, we offer the option to buy extra SAF. Jan. 10, 2020 6:19 am ET. Currently, the blend can be up to 50% aviation fuel according to several reports. Aircraft today are powered by liquid aviation fuel, made mostly from fossil fuel sources. The blend limit is 50%. We hope to bring more of these technologies closer to commercialization, which will accelerate the timeline, Reed said. So this will be a huge one, something that we all have to work out because it will have the largest impact..
