[Money Today] Kim, Kwon Woo] [Demonstration of technology in all fields of hydrogen fuel cell drone, patent application and overseas export promotion]

On the 23rd, MetaVista set a record of 10 hours and 50 minutes on a dron with 39 liters of liquid hydrogen and a 6L special tank.

Liquid hydrogen company Metavista announced on Wednesday that it set up a 10 hour 50 minute flight record by demonstrating its multi-copter hydrogen fuel cell drone using liquid hydrogen. About 390 grams of liquid hydrogen was used in the 6L special tank.

MetaVista has set a six-hour flight history with a 4L tank on its first test on July 3, and has been testing it continuously to keep track of its goal.

MetaVista demonstrated its proprietary technology in all areas of hydrogen fuel cell drones, including liquid hydrogen production from hydrogen cyanide, ultralight liquid hydrogen tanks, ultra-light multi-copter, fuel cell power management, wireless sensors and sensor fusion Stressed. In the future, the company will apply for a large number of patents on related technologies that have been delayed due to concerns about technology leakage.

A MetaVista official said, "The demand for dron battery market is expected to increase by solving short flight time which was the biggest disadvantage of existing battery drone with liquid hydrogen. I have demonstrated the possibility of being utilized. "

"Liquid hydrogen tanks, which need to maintain insulation, are very difficult to make small tanks compared to large ones." "The long-term flight of drones through the development of small liquid hydrogen power systems is a high technology of miniaturization and light weight of MetaVista's liquid hydrogen tank "He said.

As MetaVista has proven its liquid hydrogen technology, it will actively promote overseas exports. Currently, liquid hydrogen drone and dedicated hydrogen liquefier are being packaged and active consultation with overseas companies is being carried out with the aim of exporting to overseas, a company official said.

The official said, "We have demonstrated the future of high-powered drones that are approaching rapidly and will continue to commercialize them in the future." The long-time flight images of liquid hydrogen drone can be confirmed on MetaVista's official YouTube channel "He added.
