At KEET 2025, Hogreen Air is operating its largest exhibition to date, presenting its full lineup of core technologies—from

 hydrogen-powered drones to hydrogen fuel cell–based EV charging systems and hydrogen power packs.

In particular, Hogreen Air is clearly demonstrating the technological evolution of its drone systems by exhibiting actual aircraft across three development stages:

• Stage 1: Battery-powered drones

• Stage 2: Compressed hydrogen-powered drones

• Stage 3: Liquid hydrogen-powered drones

This three-stage display provides visitors with a clear, tangible view of the company’s technological roadmap and innovation trajectory.

Beyond drone systems, Hogreen Air plans to comprehensively showcase key technologies essential to the future hydrogen energy ecosystem during the exhibition, including:

• AI-based facial recognition systems

• Hydrogen fuel cell–based EV charging systems (7 kW / 12 kW / 30 kW class)

• Hydrogen power packs (4.8 kW class)

• Hydrogen tanks and fuel cell stack lineups (800 W / 1 kW / 2.4 kW / 4 kW class)

Throughout the exhibition, Hogreen Air is also conducting real-time technical consultations, drawing strong interest and continuous inquiries

 from domestic and international buyers as well as public-sector stakeholders.

Hong Seong-ho, CEO of Hogreen Air, stated:

“KEET 2025 is a venue where the technologies and market vision that Hogreen Air has been preparing have been realized in tangible form.

Beyond a simple product exhibition, we are demonstrating on-site how hydrogen-based unmanned mobility and energy infrastructure can transform cities and industries.

Building on this exhibition, we will accelerate overseas exports and expand collaborative projects with public institutions.”
