近日,德国氢动力创业公司H2FLY在斯洛文尼亚的马里博尔成功完成了世界上第一次使用液态氢作为燃料的载人飞行,标志着欧盟资助的HEAVEN项目圆满结束。在该飞行中,HY4和两名飞行员在空中飞行了3小时1分,消耗了10公斤的氢,最大储存容量为24公斤,可以持续飞行8小时。与普通飞机相比,使用液态氢可以显著降低油箱重量和体积,解锁更大的航程。对于HY4试验机来说,使用气态氢可以飞750公里,而使用液态氢可以飞1500公里,也就是两倍的距离。不过,液态氢需要低温(约-253°C),这增加了运输和加注的复杂性。通过与Deutsche Aircraft合作,他们打算用H2FLY的氢电燃料电池改装一架30座的Dornier 328示范机,并计划在2025年开始试飞。H2FLY于2015年由斯图加特德国航空航天中心和乌尔姆大学的五名工程师创立。该公司致力于整个动力系统的开发,但在必要时也会开发各个组件。2021年,H2FLY被加州公司Joby Aviation收购,后者正在开发一种电动垂直起降飞行器(eVTOL),以提供空中出租车服务。
