Developing Hydrogen Drones and Hydrogen Fuel Cells

Recognized for Technological Competitiveness in the Global Market

MOUs Signed with the U.S., Nigeria, and Others

Maintaining KRW 2.9–3.1 Billion in Annual Revenue Over the Past Three Years

Aiming to Lead the Hydrogen Value Chain and RE100

Currently, the drone can achieve flight durations of up to 90 minutes, and once liquid hydrogen technology is commercialized, the flight time is expected to extend to up to 180 minutes.

Thanks to its long-endurance capability, the drone can be applied across a wide range of industries, including GOP border fence surveillance, 

wildfire detection, missing-person searches (with facial recognition), people counting, oil leak detection, and structural crack monitoring.

Over the past three years, the company has maintained stable revenue, recording KRW 2.6 billion in 2021, KRW 3.1 billion in 2022,

 KRW 2.9 billion in 2023, and KRW 2.8 billion in 2024, sustaining an annual average of approximately KRW 2.9–3.1 billion.

This steady growth is underpinned by continuous investment in research and development.

Out of its total workforce of 18 employees, more than half—10 engineers—are dedicated to the company’s in-house R&D center, focusing on advanced technology development.

As a result of these efforts, Hogreen Air possesses a broad portfolio of core technologies, including:

• Drone airframe manufacturing technologies (compressed hydrogen and liquid hydrogen drones)

• LTE- and 5G-based drone control and communication technologies

• Hydrogen fuel cell propulsion systems for drones

• Hydrogen transfer technology using liquid hydrogen charging systems

• Ground Control System (GCS) development technologies

The company is also expanding its market presence through the development of

 hydrogen fuel cell power generation systems and hydrogen fuel cell–based EV charging systems.

Looking ahead, Hogreen Air aims to further expand its global market reach.

To achieve this, the company is analyzing high-demand markets in North America, Europe, and Asia, and developing customized strategies that reflect each region’s environmental policies and carbon neutrality regulations.

In parallel, Hogreen Air is strengthening product reliability by securing global certifications such as CE, FCC, KC, and CCC, while collaborating with global corporations and local distributors to accelerate market entry.

Additionally, the company is pursuing investment opportunities through partnerships with overseas venture capital firms and investors, while actively promoting its technology and expanding global networks through international exhibitions such as CES.

Regarding these efforts, Hong Seong-ho, CEO of Hogreen Air, stated:

“We are committed to building a regional hydrogen industry ecosystem while continuously investing in talent development and technological innovation,

 with the goal of leading the global hydrogen value chain and RE100 initiatives.

Based on our technology, we aim to grow into a global leader delivering sustainable energy solutions.”
