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.

1. Hydrogen fuel produces water vapor as exhaust

CO2 is a minor greenhouse gas. Water vapor is a major greenhouse gas. It also takes more energy to create hydrogen fuel than is produced by using it. In other words. In more ways than one its worse for the greenhouse than petro is.

2. Does anyone here know anything at all about H2 that hasn't been pounded into their

heads 20-30 years ago? This is why the US will watch China take over the industry.

It's not 1990 anymore.

--------"Iron Condor" scribbles: "Hydrogen fuel produces water vapor as exhaust"

Energy.Gov FACT:

Water Emissions from Fuel Cell Vehicles

Hydrogen fuel cell vehicles (FCVs) emit approximately the same amount of water per mile as vehicles using gasoline-powered internal combustion engines (ICEs).

---------"Iron Condor" continues with another round: " It also takes more energy to create hydrogen fuel than is produced by using it."

LA TIMES:

California invested heavily in solar power. Now there's so much that other states are sometimes paid to take it

On 14 days during March, Arizona utilities got a gift from California: free solar power.

Well, actually better than free. California produced so much solar power on those days that it paid Arizona to take excess electricity its residents weren’t using to avoid overloading its own power lines.

It happened on eight days in January and nine in February as well. All told, those transactions helped save Arizona electricity customers millions of dollars this year, though grid operators declined to say exactly how much. And California also has paid other states to take power.

The number of days that California dumped its unused solar electricity would have been even higher if the state hadn’t ordered some solar plants to reduce production — even as natural gas power plants, which contribute to greenhouse gas emissions, continued generating electricity... https://www.latimes.com/projects/la-fi-electricity-solar/

The latest Solar/Wind prices are at 0.03 cents per kWh. It takes ~50 kWh to make 1 Kg H2. That makes 1 Kg H2 cost $1.50. A Kg of H2 will move a 4,000 pound car and 4 adults ~300 miles. As more and more renewable energy comes online that price will drop. Think about that (if you can) for a few minutes.

You don't know a thing about today's hydrogen industry, do you.
