Some companies like Nestea renewable and circular solutions companyare using old cooking oils to make SAF through a process called hydro-treated esters and fatty acid (HEFA) that uses hydrogen to turn the oils into SAF, Pratik Chandhoke, technical services manager of renewable aviation at Neste, told Aviation Today. So I would say that we have a full approach looking between now, 2030 and 2050 when we really need to meet President Biden's aggressive decarbonization goals, and we believe we can fully decarbonize the aviation sector in that timeframe. Ensuring that aviation has access to the same alternative fuel policies as other transport modes, Prioritising aviation as a user of liquid alternative fuels (as other transport modes have better options), potentially by using multipliers for credits, Supporting research and technology into new production processes and feedstocks, Providing access to more cost-effective debt, debt guarantees and capital grants for production facility construction, Supporting the technical fuels approvals process at ASTM, Diverting economic support from fossil fuels towards renewable and sustainable aviation fuels, Ensuring that any government support is contingent on global sustainability standards being adhered to. renewable organic matter), or sustainable feedstock. The aviation industry has a clear vision for its use of SAFs, and will adopt only fuels made from feedstocks that can be grown or produced without the risk of unintended environmental and social consequences, such as competition with food production or deforestation. That's going to involve a number of different elements, certainly things like incentive programs to make SAF economically competitive with Jet A for airlines and economically attractive relative to transport fuels for fuel producers, access to capital to enable the development of these new production capacities by the incumbents and also the startup fuel producers, and stable and predictable government policies to reduce the risk and enable a government support mechanisms to de-risk this capital, Hussain said during the Farnborough International Airshow Connect on July 14. SAF made from renewable biomass and waste resources have the . Finally, an emissions test determines the exhaust emissions and smoke levels for the SAF. When you factor in the cost of carbon, you're looking at maybe twice the price of kerosene.". 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. Camelina: an energy crop, with high lipid oil content. (202) 204-5244 fax, info@eesi.org 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. Alaska Air Group GEO Ben Minicucci spoke in a June 30 Washington Post Live event about the companys strategy to get to net zero emissions by 2040 and cited SAF as the most impactful solution in their plan. Read all of the articles in the Sustainable Aviation Fuel series. A summary list of the cons outlined in the guide below: May Currently Be More Costly Than Traditional Jet Fuel, Consumers Will Likely Bear The Increased Cost For Sustainable Aviation Fuel, May Only Be Effective For Specific Types Of Flights, Still Uses Conventional Jet Fuel In The Final Fuel Product, The Scale Of Use Of Sustainable Aviation Fuel Is Not Yet Where Conventional Jet Fuel Is, & There Might Be Barriers To Growth, if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'bettermeetsreality_com-large-mobile-banner-1','ezslot_8',117,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-large-mobile-banner-1-0'); Has Some Practical/Technical Challenges, Some Question How Renewable Some Feedstocks Actually Are, Some Question How Sustainable Some Feedstocks Actually Are, Is Not The Only Sustainability Solution For The Aviation Industry, Some Reports Indicate That Hydrogen Planes Are The Mid To Long Term Solution, A fuel (which some reports refer to as a type of biofuel) used to power aircrafts that has claimed sustainability benefits compared to traditional aviation fuel (i.e. bp.com mentions that aside from a need to reduce the cost of SAF, government policy and policy incentives that reduce investment risk in increased production and supply, research, development and commercialization of improved production technologies and innovative sustainable feedstocks, and advanced technologies to process feedstocks more efficiently at greater scale and investment in the development of sustainable and scalable feedstock options may also be short to long term barriers to the growth of SAF. Its hard to match conventional jet fuel for energy density when it comes to keeping planes in the air. Heres how. Some may be more suitable than others in certain areas of the world. Older aircrafts with less sustainable aircraft systems may be able to increase their in the air lifespan by lowering their carbon footprint with sustainable aviation fuel. 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. 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. Since SAFs were certified for commercial aviation in 2011, more than 225,000 commercial flights have been powered by SAFs and six billion litres of SAFs are in current forward purchase agreements by airlines. The industry has called on governments to assist potential SAF suppliers to develop the necessary feedstock and refining systems at least until the fledgling industry has achieved the necessary critical mass and prices drop thanks to economies of scale. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page. "We used about 100 million liters of sustainable aviation fuel in 2021," Willie Walsh tells CNBC. We've moved! Sustainable Aviation Fuels. We in the Department of Energy, working closely with USDA, developed a billion tonnes report, which is really 15 years of resource assessment and understanding the science behind the biomass feedstocks, and what we have done is identified that the nation could produce one billion tons of sustainable biomass feedstock pretty much without interrupting the existing markets for food feed, fiber, and any other possible uses of that biomass, Reed said. This first installment in a four-part series of articles reviewed the basics of SAF. They point out that the way the fuel is sourced and produced is where emissions might be saved. Production capacity is limited but growing. Published Jul 16, 2021. EESI advances science-based solutions for climate change, Battery technology for electric flight is improving. 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. Ultimately, they will be willing to pay," he added. Our suite number is now 400. There may also be an opportunity for farmers to create an additional income. Naveed Hussain, chief technology officer and vice president and general manager at Boeing Research & Technology, said that to accelerate the scale of SAF available, there need to be incentive programs. 7 technical pathways exist. cnbc.com indicates that the increased costs for SAF over traditional jet kerosene will ultimately be paid for by the consumerif(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'bettermeetsreality_com-sky-1','ezslot_21',140,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-sky-1-0'); This obviously makes air travel more expensive for consumers, and they may have no choice on certain flights that use SAF, Theres also the query of whether this adds increased pressures on lower income citizens who usually travel on budget flights, May Only Be Effective For Medium To Long Term Haul Flights. RD benefits from favorable tax policy, making its production more profitable; it dwarfs SAF output nationally. For example, using the waste gases produced as a by-product in steel manufacturing to produce sustainable aviation fuel is showing great promise. 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. The only difference is that the feedstock is from non-fossil sources.. popsci.com also mentions that these costs might be a significant issue in less fuel efficient plane models per mile the plane has to fly (because the planes are using more fuel per mile). Increased production will improve the economies of scale for these sustainable fuels, which made up less than 0.1 percent of the 96 billion gallons of total global commercial aviation fuel consumption in 2019. They thrive off carbon dioxide, which makes them ideal for carbon sequestration (absorbing CO2) from sources like power plants. (Neste). 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. 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. They also indicate that algae feedstock production could be used in other markets other than aviation too. Nor does it take into account SAFs made from non-biological sources, such as municipal waste. However, continued R&D may result in wider application in the future. Fuels that dont contribute to deforestation, and that use renewable energy to produce the fuel might emit less CO2. Since the certification of SAFs in 2011, more than 225,000 commercial flights have been powered by SAFs and six billion litres of SAFs are in current forward purchase agreements by airlines. Cowen's stocks to play it, The environmental footprint of aviation is considerable, with the World Wildlife Fund describing it as "one of the fastest-growing sources of the greenhouse gas emissions driving global climate change." We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. Achieving . 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 . SAF is considered a drop-in fuel and is certified for use blended with conventional fuel up to a maximum 50 percent mixture, requiring no change in aircraft engines or fueling infrastructure. This guide compliments our separate guide on whether sustainable air travel is possible.

SAF is currently more costly than traditional fossil jet fuel [and thats because of] a combination of the current availability of sustainable feedstocks and the continuing development of new production technologies. Alaska Airlines is a partner as well. Newer engines do not have this problem, and SAFs have been performance tested at 100% in some new aircraft. In terms of content, aircraft maker Airbus has described sustainable aviation fuels as being "made from renewable raw material." Plastics for example arent produced from renewable feedstocks, and neither are synthetic fibres used in textiles. "We used about 100 million liters of sustainable aviation fuel in 2021 that's a very small amount compared to the total fuel required for the industry.". Copyright Environmental and Energy Study Institute (EESI). This is probably the biggest enabler to get to 2040. Achieving this goal, however, will be a difficult challenge. Shifting to H2 as a fuel source presents a significant set of challenges in production, storage and infrastructure, aircraft configuration and engine modification requirements. qantas.com indicates that for one of their routes where blended SAF is used, carbon emissions are reduced by around 10 per cent. The blending limit is 50%. 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.. 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. These residues can be processed into synthetic fuel. [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. We're able to test those technologies there, we're able to look at how that's working, and it helps drive our research strategy.. Aviation is steadily growing worldwide as well as in the European Union (EU). However, these feedstocks will not be enough to sustain the amount of SAF the aviation industry will need to meet its goals while following sustainable practices. 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). It's not something that happens quickly, it's a sophisticated process technology. This creates a loop: plants absorb carbon from the atmosphere, then are turned into SAF, which releases the carbon back into the atmosphere when it is burned. The Sustainable Skies Act would establish a $1.50 per gallon tax credit for SAF that reduces emissions by 50 percent. Washington, DC 20036-6101, (202) 628-1400 phone The WWF also says air travel is "currently the most carbon intensive activity an individual can make.". SAF are estimated to generate 80% less carbon emissions than conventional kerosene , and have . Got a confidential news tip? 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 . From cnbc.com: 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, Some Question If Some Sustainable Aviation Fuels Actually Decrease Emissions At All, popsci.com has a good article outlining this point. Relative to fossil fuels, SAFs result in a reduction in CO2 emissions across their lifecycle. That type of potential lead Boeing to partner with SkyNRG in an effort to accelerate SAF development globally. The LCFS gives credits to fuels with low CIs and deficits for high CIs. Looking ahead, Walsh said airlines had ordered 14 billion liters of SAF. petroleum-based jet fuel), if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[336,280],'bettermeetsreality_com-large-mobile-banner-2','ezslot_9',120,'0','0'])};__ez_fad_position('div-gpt-ad-bettermeetsreality_com-large-mobile-banner-2-0');Although there isnt yet an internationally agreed upon definition of sustainable aviation fuel, theres a commonly listed sustainability benefit that it reduces carbon emissions, Currently, the reduction might be for short to medium haul flights, There can be other claimed sustainability and environmental benefits of SAF too (which we outline in the guide below). 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. While direct power-to-liquid options are based on technically proven steps, the process is currently expensive and needs further development. 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.
