Hogreen Air’s Liquid Hydrogen Drone Ranks ‘Top 10’ in Global Technology Competitiveness Evaluation
Page info
Hogreen Air Co., Ltd. (CEO Sung-ho Hong), a hydrogen fuel cell–based mobility specialist, announced on the 5th that its liquid hydrogen drone,
a next-generation model overcoming the limitations of conventional battery-powered drones, has ranked Top 10 in a global technology competitiveness evaluation.
Hogreen Air’s liquid hydrogen–based propulsion system was ranked 9th worldwide in a recent technology competitiveness assessment conducted by global market research firm QY Research, which evaluated hydrogen drone manufacturers worldwide.
Hogreen Air is the only Korean hydrogen drone company to rank within the global Top 10, placing ahead of a major domestic Company D.
While conventional lithium battery–based drones typically offer flight times of only 20 to 30 minutes, Hogreen Air’s liquid hydrogen drone is capable of over two hours of continuous flight.
It demonstrates clear advantages over battery-powered and gaseous hydrogen drones in terms of high energy density, long-endurance flight,
and low-temperature stability, making it highly applicable across a wide range of fields, including defense, industrial monitoring, and disaster response.
The company’s technological capabilities have already been recognized both domestically and internationally.
Following its official invitation to exhibit at the 2025 Asia-Pacific Economic Cooperation (APEC) K-Culture Advanced Future Industry Pavilion,
Hogreen Air also received a T-2 technology credit rating from NICE D&B, Korea’s leading technology credit rating agency.
This rating is awarded only to companies ranked within the top 5% of all evaluated firms for technological excellence.
In addition, Hogreen Air became the first company in Gwangju to be designated as a government-certified
“Hydrogen Specialized Company” by the Ministry of Trade, Industry and Energy.
Hogreen Air is also gaining recognition in the hydrogen fuel cell power generation sector. Its 7 kW-class Proton Exchange Membrane Fuel Cell (PEMFC)
stationary fuel cell system has successfully passed the final completion inspection by the Korea Gas Safety Corporation (KGS).
This achievement officially verifies that the company’s building-use fuel cell system meets both advanced technological standards and stringent safety requirements,
marking a critical milestone for entry into the urban distributed power generation market.
From the 3rd to the 5th, Hogreen Air showcased its liquid hydrogen drone at the Korea Tech Festival, held at COEX in Seoul.
CEO Sung-ho Hong stated,
“Liquid hydrogen drones are already internationally validated technology,” adding,
“We will further strengthen our position as a technology leader not only in the global hydrogen drone market, but also across hydrogen-based power systems and the broader eco-friendly infrastructure industry.”
