And in some cases, it may require a wholesale redesign of the plane.<\/p>\n\n\n\n<p>This will not be easy.

According to the\u00a0International Air Transport Association\u00a0(IATA), SAF could contribute <a href=\"https:\/\/www.iata.org\/en\/iata-repository\/pressroom\/fact-sheets\/fact-sheet---alternative-fuels\/\" target=\"_blank\" rel=\"noreferrer noopener\">around 65% of the reduction in emissions<\/a> needed by aviation to reach net-zero in 2050.<\/p><\/div><div class=\"expander-content\"><p>In terms of redesigns, SAF is the easy option. SAF can \u2018drop in\u2019 &#8211; which means that it can be blended with conventional jet fuel and, in some cases (\u2026more in future), replace conventional jet fuel entirely. This means that SAF requires little to no redesign. Airbus already has commercial and military aircraft capable of flying with up to a 50% blend of SAF, and aims for 100% by 2030. <a href=\"https:\/\/stratcommand.blog.gov.uk\/2020\/10\/16\/aircraft-algae-and-alcohol\/\" target=\"_blank\" rel=\"noreferrer noopener\">The UK MOD has begun accepting up to 50% drop<\/a> in from its fuel suppliers and has already demonstrated a <a href=\"http:\/\/www.apple.com\/uk\" target=\"_blank\" rel=\"noreferrer noopener\">100% SAF flight<\/a>.<br><br>SAF, it should also be noted, can be produced in a carbon neutral way, but take CO2 out at ground level and return it at altitude \u2013 so, whilst a good deal better than kerosene, and an excellent transition fuel, SAF is not a completely green solution. <br><br>It\u2019s worth mentioning that the production pathway of SAF (and thus its scalability) is an important factor. For example, it\u2019s important to ensure that SAF created from biological sources (like forestry residues) does not compete with other sectors that need to use those same resides, like the paper industry. The EU and US are pursuing different approaches to this challenge.

Due to a later start, hydrogen has a shorter timeline and is likely to start seeing major aviation deployment in the 2030s. When combusted, hydrogen reacts with oxygen to create energy and water vapour, and so has no carbon emissions. If the hydrogen is produced from green sources, flights could, in theory, be carbon neutral (though it is unlikely we will completely eliminate emissions from hydrogen\u2019s production, storage and transport infrastructure).<\/h5><\/div><div class=\"expander-content\"><p>The energy density of hydrogen, by mass, is three times greater than kerosene, which makes hydrogen very attractive as an energy carrier. However, it has less energy by volume than kerosene: six times less for gas at high pressure (700 bars) and three times less for liquid (which requires it to be cooled to -253\u00b0C). So liquid hydrogen is more viable but will still require more space for storage than fuel, which will challenge aircraft shape and architecture.<br>\u00a0<br>As such, it will likely require planes to be redesigned to accommodate larger fuel tanks.\u00a0 This, for example, could create an opportunity to improve aircraft by moving the fuel storage &#8211; for example, taking it out of the wings. The wings could then be made thinner, generating less drag and increasing fuel efficiency. It also creates complex challenges around the design, engineering and materials choices for hydrogen storage tanks, fuel injection, and the engine itself &#8211; which would need to be modified to deal with this new fuel source.<br><br><br>H2 (whether combusted or used in fuel cells) also produces contrails\/water vapour, the dispersion of such clouds (contrail cirrus clouds) can trap heat that radiates from the earth below, increasing warming. Combusting it also produces nitrogen oxides (\u2018NOx\u2019) which could be a cause of smog, acid rain, and respiratory problems in humans, though it produces less of these than kerosene.<br><br><br>Hydrogen could also be used to power fuel cells, which drive an electric powertrain, and which have no waste emissions. A few recent test flights, including from startups <a href=\"https:\/\/www.zeroavia.com\/do228-first-flight\" target=\"_blank\" rel=\"noreferrer noopener\">ZeroAvia<\/a>\u00a0and <a href=\"https:\/\/www.businesswire.com\/news\/home\/20230302005768\/en\/Universal-Hydrogen-Successfully-Completes-First-Flight-of-Hydrogen-Regional-Airliner\" target=\"_blank\" rel=\"noreferrer noopener\">Universal Hydrogen<\/a>, are promising.

Given the safety-critical nature of aerospace, they will also take a lot of testing before passengers are allowed anywhere near them. Some of this just has to be done, but some elements can be sped up through new digital engineering approaches.<\/p>\n\n\n\n<p>Digital design tools can help scope design and architecture, engineering, as well as the electrical, mechanical systems and physical domains, and how they should join up. Modelling \u2013 when designed by aerospace entering experts &#8211; can help optimize and define the most effective configuration for fuselages, tanks and wings, predict the best materials choices, and design the integration of electrical, electronic, and mechanical components. Even Artificial Intelligence (AI) can help propose optimal designs if provided with clear input criteria, reducing the number of false starts, and the need to produce early physical prototypes.<\/p>\n\n\n\n<p>Simulations and physics-based systems modelling can be used for understanding important properties, like thermal management, which will be critical for the safety and efficiency of designs of battery packs, and engines using new fuel sources stored at different pressures and temperatures.<\/p>\n\n\n\n<p>Software design will also be increasingly important for system management, as powertrains are electrified and systems need to be monitored and held at particular states throughout the flight.<\/p>\n\n\n\n<p>Model-based system engineering (MBSE) &#8211; \u2018the application of modeling to support system requirements, design, analysis, verification and validation (V&amp;V) activities\u2019 \u2013 allows designers to take a holistic view; analyzing the aircraft system as a whole throughout its entire lifecyle, and identify the interactions between its components. The digital approach can help to accelerate projects, hastening the Validation &amp; Verification (V&amp;V) certification process, for example, by allowing more of the test and evaluation work to be done digitally.<\/p>\n\n\n\n<p>AI can also be used to translate flight data into scenarios for simulated testing from the component level up to virtual flight tests in varied and challenging conditions. This helps spot challenges early, reducing risk in costly real-life flight tests \u2013 though these, of course, must be done eventually. Once they are, detailed data collection, post-processing and visualization can help understand risks and improvements &#8211; which can be fed back into the digital model in order to improve the design.<\/p>\n\n\n\n<p>Airbus\u2019 <a href=\"https:\/\/www.airbus.com\/en\/innovation\/disruptive-concepts\/digital-design-manufacturing-services\">Digital Design Manufacturing and Services (DDMS) program<\/a> is a good example of &#8216;digital-first\u2019 in action. It has been used to help develop the Future Combat Air System and the A321XLR, which Airbus claims burns 30% less fuel than previous generation aircraft.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-no-silver-bullets-but-many-choices\">No silver bullets, but many choices<\/h2>\n\n\n\n<p>The commercial aviation community agrees on a mixture of propulsion solutions, but there are no \u2018silver bullets\u2019.<\/p>\n\n\n\n<p>In the near future, SAF-powered aircraft will likely predominate, as SAF requires no modification to airframes and is an improvement on conventional fuel from a sustainability perspective. SAF alone won\u2019t get us to Net Zero, however.<\/p>\n\n\n\n<p>This leaves us with hydrogen and electricity. Electricity is always likely to be limited to short distance flights due to the weight of batteries. Green hydrogen will likely be the eventual solution for commercial flights, due to its highly sustainable credentials and ability to be stored on board as a liquid fuel. Nonetheless, hydrogen will add storage and weight to current aircraft compared to kerosene, and so SAF is likely to be the best option for long-distance flights, at least in the medium term.<\/p>\n\n\n\n<p>Neither electric nor hydrogen propulsion is anywhere near ready to meet the full needs of commercial aviation, but both are progressing rapidly. Both will require major redesigns of aircraft, followed by endless optimization and rigorous testing. Those that get through this process first will have a significant competitive advantage. Digital engineering will likely determine the winners.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/section>\n\n\n\n<section class=\"section section--expert-slider wrapper-people-slider wp-block-cg-blocks-wrapper-people-slider undefined\"><div class=\"container\"><div class=\"content-title\"><h2 data-maxlength=\"34\" class=\"people-heading-title\">Meet our expert<\/h2><\/div><\/div><div class=\"slider slider-boxed\"><div class=\"container\"><div class=\"slider-window\"><div class=\"slider-list\">\t\t<div class=\"slide\">\n\t\t\t<div class=\"box\">\n\t\t\t\t<div class=\"row\">\n\t\t\t\t\t<div class=\"col-md-6 col-lg-4 box-img-wrapper\">\n\t\t\t\t\t\t<img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.capgemini.com\/mx-es\/wp-content\/uploads\/sites\/28\/2025\/06\/Sebastien-Kahn.jpg\" alt=\"Sebastien Kahn\"\/>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"col-md-6 col-lg-8 box-inner\">\n\t\t\t\t\t\t<div class=\"row title-social-media-header\">\n\t\t\t\t\t\t\t<div class=\"col-md-12 col-lg-6 mbl-social-icon\">\n\t\t\t\t\t\t\t\t<ul class=\"social-nav\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li>\n\t\t\t\t\t\t\t\t\t\t\t<a class=\"subnav-button--form\" href=\"javascript:void(0)\" aria-label=\"contact us\" data-bs-toggle=\"modal\" data-bs-target=\"#WPB31acc8da_bf76_4913_94a9_2efe04d43133\" data-bs-expert-title=\"1\">\n\t\t\t\t\t\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"ico-form\"><\/i>\n\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><a aria-label=\"Linkedin\" target=\"_blank\" href=\"https:\/\/www.linkedin.com\/in\/sebastien-kahn\/\"><i aria-hidden=\"true\" class=\"icon-li\"><\/i><\/a><\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"col-md-12 col-lg-6 box-container\">\n\t\t\t\t\t\t\t\t<div class=\"box-title\">\n\t\t\t\t\t\t\t\t\t<h3 class=\"people-profile-title\">Sebastien Kahn<\/h3>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span>Vice President Sustainability &amp; Industry, A&amp;D Sustainability Lead, ÎÚÑ»´«Ã½<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"col-md-12 col-lg-6 social-box-container dkt-social-icon\">\n\t\t\t\t\t\t\t\t<ul class=\"social-nav\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li>\n\t\t\t\t\t\t\t\t\t\t\t<a class=\"subnav-button--form\" href=\"javascript:void(0)\" aria-label=\"contact us\" data-bs-toggle=\"modal\" data-bs-target=\"#WPB31acc8da_bf76_4913_94a9_2efe04d43133\" data-bs-expert-title=\"Sebastien Kahn\">\n\t\t\t\t\t\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"ico-form\"><\/i>\n\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<li><a aria-label=\"Linkedin\" target=\"_blank\" href=\"https:\/\/www.linkedin.com\/in\/sebastien-kahn\/\"><i aria-hidden=\"true\" class=\"icon-li\"><\/i><\/a><\/li>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"people-info\">For the past 15 years, S\u00e9bastien Kahn has been supporting public and private players in their major ecological transition projects, in particular energy decarbonization strategies, hydrogen or electric ecosystems, and the associated financing and skills plans.
