And all the hard work has come to fruition, with the successful completion of the world\u2019s first crewed liquid hydrogen-powered flights.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Before any aviation history enthusiast out there goes \u201cbut what about the Tupolev Tu-155?\u201d \u2014 yes, the Soviets did try out liquid hydrogen as fuel 35 years ago, but only for one of the three engines. In contrast, H2FLY\u2019s HY4 has now operated using only liquid hydrogen (as opposed to the gaseous kind) as fuel, relying solely on the hydrogen fuel-cell powertrain for the entire flight.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On Thursday, this TNW reporter was present for the fourth in a <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/watch-movies-tv-seriess\/\" data-internallinksmanager029f6b8e52c=\"8\" title=\"Watch Movies &amp; TV Series\" target=\"_blank\" rel=\"noopener\">series<\/a> of test flights. The event marked the culmination of Project HEAVEN, an EU-funded partnership undertaking to demonstrate the feasibility of using liquid, cryogenic hydrogen in aircraft.

If using up the aircraft\u2019s full storage capacity of 24kg, it could stay up for 8 hours.\u00a0<\/span><\/p>\n<div class=\"inarticle-wrapper latest channel-cta hs-embed-tnw\">\n<div id=\"hs-embed-tnw\" class=\"channel-cta-wrapper\">\n<div class=\"channel-cta-img\"><img decoding=\"async\" class=\"js-lazy\" src=\"https:\/\/s3.amazonaws.com\/events.tnw\/hardfork-2018\/uploads\/visuals\/tnw-newsletter.png\"\/><\/div>\n<p><noscript><img decoding=\"async\" src=\"https:\/\/s3.amazonaws.com\/events.tnw\/hardfork-2018\/uploads\/visuals\/tnw-newsletter.png\"\/><\/noscript><\/p>\n<div class=\"channel-cta-input\">\n<p class=\"channel-cta-title\">The &lt;3 of EU tech<\/p>\n<p class=\"channel-cta-tagline\">The latest rumblings from the EU tech scene, a story from our wise ol&#8217; founder Boris, and some questionable AI art.

All in all, this summer was H2FLY\u2019s eight flight test campaign. The hydrogen-electric HY4 has been flying since 2016, but this summer\u2019s breakthrough consists of operating the plane on liquid hydrogen, as opposed to hydrogen as gas.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Liquid hydrogen is more energy dense than its gaseous counterpart. That means that it requires significantly lower tank weights and volume. In the world of air transport, especially when retrofitting planes, this equals not having to throw out as many passenger seats, or reduce cargo space, i.e. payload.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But perhaps more significantly, it unlocks a much greater range. For the HY4 test aircraft, this equals 750km on gaseous hydrogen vs. 1,500km on liquid \u2014 or double the distance. On the other hand, liquid hydrogen requires cryogenic temperatures (around -253\u00b0C), which adds to the complexity of transporting and refuelling.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Retrofitting_existing_airframes_with_hydrogen_fuel-cell_propulsion_system\"><\/span>Retrofitting existing airframes with hydrogen fuel-cell propulsion system<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The HY4, made out of glass fibre and carbon fibre, will not go into commercial production. The next step from H2FLY will now be to scale the fuel-cell system to megawatt capacity. The H2F-175 system will unlock not only longer range, but also altitudes of up to 27,000 feet. In a partnership with Deutsche Aircraft, the two intend to retrofit a 30-seat Dornier 328 demonstrator with H2FLY hydrogen-electric fuel cells and begin test flights by 2025.\u00a0<\/span><\/p>\n<figure>\n                <iframe loading=\"lazy\" srcdoc=\"&lt;style&gt;*{padding:0;margin:0;overflow:hidden}html,body{background:#000;height:100%}img{position:absolute;top:0;left:0;width:100%;height:100%;object-fit:cover;transition:opacity .1s cubic-bezier(0.4,0,1,1)}a:hover img+img{opacity:1!important}&lt;\/style&gt;&lt;a href=\" https:=\"\" src=\"https:\/\/img.youtube.com\/vi\/uj-Yw3on2tI\/hqdefault.jpg\" style=\"top: 50%;left:50%;width:68px;height:48px;transform:translate3d(-50%,-50%,0)\" height=\"240\" width=\"320\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\"><\/iframe><\/p>\n<\/figure>\n<p><!--resp-video-container--><span style=\"font-weight: 400;\">The company\u2019s timeline is slightly more restrained <\/span><span style=\"font-weight: 400;\">than some of its competitors<\/span><span style=\"font-weight: 400;\">, but H2FLY co-founder and CEO, Dr Josef Kallo, says he foresees that an upscaled system will be capable of powering a 40-seat capacity regional plane with a range of about 2,000km by the end of the decade.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cAs an engineer, I can say that a 40-seater hydrogen-powered plane is a question of money and time. After that it becomes visionary,\u201d Kallo stated. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, he also added that the tests thus far indicate that it would be possible to scale up to 4MW + 4MW powertrains, which could propel larger aircraft for 80 to 100 passengers. He also does not exclude entirely new aircraft designs from new manufacturers, including for instance a blended wing body.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Liquid_hydrogen_potential_%E2%80%98gamechanger_for_commercial_aviation\"><\/span>Liquid hydrogen potential \u2018gamechanger\u2019 for commercial aviation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Something else a future of clean-burning, hydrogen-powered aviation requires is \u2014 other than the actual fuel \u2014 is refuelling infrastructure.
