陕西研制液氢航空地面保障系统完成全流程一体化测试Shaanxi Develops Liquid Hydrogen Aviation Ground Support System, Completes Full-Process Integrated Testing
10月9日，记者从陕西省工业经济联合会获悉，陕西同尘和光低温科技有限公司自主研制的液氢航空地面保障系统，日前在河北邢台威县通用机场完成液氢航空地面保障全流程一体化测试，实现液氢槽车运输、地面存储到飞机储罐加注全流程贯通，可为多款氢能飞机试飞提供完整地面保障，这标志着陕西液氢航空应用迈上新台阶。
同尘和光总经理李晓刚介绍，氢能飞机使用的液氢为零下253摄氏度极低温燃料，对保冷、安全控制要求极高，国内以往多为单环节验证。本次测试完成槽车卸车、储罐存储、飞行器加注等核心环节，系统采用模块化平台设计，可适配吨级eVTOL（电动垂直起降飞行器）、固定翼无人机等不同构型氢能飞行器。
项目融合航天级绝热保冷技术，攻克大流量低温加注、BOG蒸发气体回收、安全联锁等关键工程技术。同尘和光2025年已完成吨级液氢eVTOL试飞，本次是从单机试飞迈向平台化保障的重要进展，将为低空经济绿色发展补齐关键基础设施短板。
同尘和光成立于2023年7月，由陕西氢能产业链链主企业陕西维纳数字科技股份有限公司联合西安交通大学能源与动力工程学院液氢领域教授团队共同组建，目前已形成氢液化、液氢加注、高效储存、轻量化、液氢无人机系统五大核心技术能力。
业内人士表示，液氢被视为支撑氢能航空与低空经济规模化发展的关键能源载体，此次全流程一体化测试的实现，意味着我国在液氢航空地面保障这一细分环节逐步补齐短板，为氢能飞行器从试验走向常态化运营提供了基础设施支撑。
On October 9, reporters learned from the Shaanxi Industrial Economy Federation that Shaanxi Tongchen Heguang Cryogenic Technology Co., Ltd. independently developed a liquid hydrogen aviation ground support system. Recently, it completed an integrated full-process test of liquid hydrogen aviation ground support at the General Airport in Weixian, Xingtai, Hebei. The system achieves full-process integration from liquid hydrogen tanker transportation and ground storage to aircraft tank refueling, capable of providing complete ground support for test flights of various hydrogen-powered aircraft. This marks a new milestone in the application of liquid hydrogen aviation in Shaanxi.
Li Xiaogang, General Manager of Tongchen Heguang, introduced that the liquid hydrogen used by hydrogen-powered aircraft is an ultra-low temperature fuel at minus 253 degrees Celsius, with very high requirements for thermal insulation and safety control. Previously, domestic tests mostly verified single links. This test completed core links including tanker unloading, tank storage, and aircraft refueling. The system adopts a modular platform design, adaptable to different configurations of hydrogen-powered aircraft such as ton-class eVTOL (electric vertical take-off and landing aircraft) and fixed-wing drones.
The project integrates aerospace-grade thermal insulation and cryogenic cooling technologies, overcoming key engineering challenges such as high-flow low-temperature refueling, BOG gas recovery, and safety interlocks. Tongchen Heguang completed a ton-level liquid hydrogen eVTOL test flight in 2025, and this marks an important step from single-machine test flights toward platform-level support, filling crucial infrastructure gaps for the green development of the low-altitude economy.
Tongchen Heguang was established in July 2023, jointly set up by Shaanxi Vina Digital Technology Co., Ltd., the leading enterprise in Shaanxi's hydrogen energy industry chain, along with a team of professors specializing in liquid hydrogen from the School of Energy and Power Engineering at Xi’an Jiaotong University. It has currently developed five core technological capabilities: hydrogen liquefaction, liquid hydrogen refueling, efficient storage, lightweight technology, and liquid hydrogen UAV systems.
Industry insiders indicate that liquid hydrogen is regarded as a key energy carrier supporting the scale development of hydrogen-powered aviation and the low-altitude economy. The achievement of this full-process integrated test signifies that China is gradually filling the gaps in liquid hydrogen aviation ground support, providing infrastructure support for hydrogen-powered aircraft to move from experimental tests to routine operations.
