Towards the Social Implementation of Drones: Clearing the Flight Time Barrier with "Hydrogen x Drones"

We endorse April Dream, an initiative to make April 1st a day for announcing dreams. This press release is Robodex's dream.

Robodex's dream is for drones to become an ordinary part of society, not a special one. Drones are already expected to have many possibilities. However, in reality, the constraint of "flight time" is a major barrier preventing these possibilities from fully expanding.

To overcome this barrier, we are working on developing hydrogen-powered drones as a new option for long-duration flight. However, our goal is not the "widespread adoption of hydrogen drones themselves," but for drones to be used as a matter of course in society, supporting people's lives and industries.

To achieve this, we continue to take on challenges every day.

**The Near Future Robodex Seriously Envisions** Drones becoming naturally integrated into daily life, routinely supporting people's lives and industries. We envision such a future. Inspection, monitoring, and maintenance of infrastructure, deployment in times of disaster, and industrial applications. Drones hold the power to integrate into these daily routines and support people.

**One of the Few in Japan! Committed to "Domestic Production" for Development** Japan's drone industry relies heavily on imports. Issues arise with risks such as manufacturing halts due to political reasons or the development of security problems.

Robodex is committed to "domestic production" for everything. Even now, and in the future where drones will be even more necessary, we can deliver to users through a stable domestic supply chain, and because of domestic manufacturing, we can provide them with peace of mind, free from security concerns.

Currently, achieving complete domestic production is not easy... As the industry develops, we will continue to strive to set precedents so that the entire industry can choose "complete domestic production" in the future!

**No Worries About Hydrogen Supply Either!** To enable long-duration drone flight, we are combining hydrogen with drones. As you might guess, we've received many questions like, "Where do you get hydrogen?" Please rest assured!

We completed the development of a mobile hydrogen station in May 2025. Equipped with an explosion-proof room on the back of a truck, it can refuel hydrogen wherever the truck can go!

Currently, we are working on equipping this truck with a hydrogen generator to produce hydrogen on-site and refuel it on-site!

Furthermore, we believe that if we can also create semi-mobile hydrogen stations in a container format, rather than just trucks, hydrogen will become even more accessible and easier to use. We will continue to strive to make hydrogen supply more convenient!

**A Frank Announcement!!!** Frankly speaking, we receive pointed questions daily such as, "Is hydrogen safe?", "Do I need to prepare a truck to fly a drone?", and "How is it different from battery-powered drones?"

For the future we envision, we cannot wait for other factors to move; we must pioneer our own path.

Therefore, for the future social implementation of drones and the widespread adoption of hydrogen energy, we will engage with users to help them learn and deepen their understanding. Starting from fiscal year 2026 (though we've been working on it quietly until now, we're getting serious!), we will actively disseminate information on technology and operations from the perspective of those involved in development.

We will clearly share on-site verification results, challenges in actual operation, and our approach to safety, actively working to promote understanding of drones and hydrogen energy.

We believe that the social implementation of drones is not achieved solely through technological evolution but progresses hand-in-hand with the understanding of users and society as a whole. As a bridge builder, our company will continue its efforts to connect technology and society.

**About Robodex Inc.** Robodex Inc. (Headquarters: Yokohama City, Kanagawa Prefecture; President and Representative Director: Daisuke Kaihata) is a pioneer in hydrogen drones, working on the development of drones capable of long-duration flight. Committed to "domestic production," we guarantee high security and safety in any situation.

Leveraging the technological expertise cultivated through hydrogen drones, we are also expanding our business into the development of compact hydrogen mobility, hydrogen generators, and hydrogen supply.
