There is no need for customer to refuel hydrogen directly to the tank inside the fuel cell because a fueled hydrogen tank will be delivered to them ahead of time.
The used-up hydrogen tank can be separated in one touch via the fuel cell system. The customer can use the fuel cell again immediately after inserting the new filled hydrogen tank.

While liquid hydrogen is denser than the high-pressure hydrogen we use and, therefore, more hydrogen can be stored per volume, it will still take some time for it to be commercialized since the equipment needed to refuel liquid hydrogen and to vaporize liquid hydrogen into hydrogen gas is heavy. Our company’s powerpacks can also be used with liquid hydrogen once the related infrastructure is built.

If you are a user of existing battery-powered drones, you can control it easily. Also, thanks to the easy replacement method of hydrogen tanks, you can replace the tank within 10 minutes at the maximum, which is easier and simper than operating and controlling batteries. When you purchase our product, our Sales Manager will visit you and provide basic training.

Yes, it can be used right away. We provide a mount package with the powerpack to make equipment easier. If you purchase a powerpack, the sales manager will personally visit you explain about how to use the pack and how to change the settings.

The warranty period of a powerpack is 1 year. With the exception of M600, if there is any problem with your drone or powerpack, all related services will be provided from South Korea. As for the M600 kit, Doosan Mobility Innovation will provide warranty for the product unless the problem was caused by an operating miss of the user.

You only need to bear the cost of hydrogen needed for the operation of the powerpack. Also, you won’t have to pay a cent in the first year since we provide a 1-year free hydrogen refueling coupon for each of our first-time customers.

First of all, it is possible to monitor the powerpack or flight information in real time remotely via an ultrahigh-speed communications module and cloud. In particular, you can operate your drone safely as you can monitor the remaining hydrogen amount accurately in real time.
And for our LTE module-equipped powerpack, we are currently building a system for remote diagnostics.

You can identify the problem on your own using the User Manual, and if you have trouble identifying it yourself, you file a claim report through our website to register details about the defect/breakdown. After you file your claim report, a manager will get back to you as soon as possible to inform you whether the problem can be fixed and what the procedures are.
