Hogreen Air participated in the 'SWEET 2021 (Solar, Wind & Earth Energy Trade Fair 2021),' held at the Kim Dae-jung Convention Center in Gwangju from July 8th to 10th.

Hogreen Air specializes in establishing stable systems in the drone industry and provides customized services for various sectors such as defense, industry, education, and services. The company aims to innovate in accident and safety management for unmanned aerial vehicles (UAVs) by promoting the efficient operation and services of drones. It was founded with a focus on the proliferation of green energy through hydrogen fuel cells.

At the exhibition, Hogreen Air showcased drones equipped with hydrogen fuel cells.

The company, known for manufacturing and selling various drone hardware, software, and comprehensive drone solutions, has developed the 'Hydrogen Power Pack,' a power generator system combining hydrogen fuel cells and hydrogen tanks. Hogreen Air holds numerous patents related to drones, including 'LTE-Based High-Speed Encryption of Video Data' and 'Unmanned Pesticide Supply System.' They are involved in drone development across various industries such as agriculture, defense, and AI.

Hogreen Air's PEM (Polymer Electrolyte Membrane) fuel cell platform is characterized by high-performance air-cooled fuel cells that use minimal peripheral components, ensuring reliability and cost-effectiveness. This system produces clean DC power from supplied hydrogen, emitting only pure water vapor by combining with oxygen from the air. Additionally, it operates with minimal noise and vibration, offering environmental advantages over conventional diesel generators.

A representative from Hogreen Air mentioned, "We have signed an exclusive distribution agreement with Intelligent Energy, a UK-based company, handling various types of hydrogen fuel cells (FCM800 series, FCPM for UAVs)." He explained that by combining Intelligent Energy's hydrogen fuel cells (2.4kW FCPM) with their hydrogen tanks, they could significantly extend the flight time to over 2 hours, addressing the limitations of traditional lithium-polymer batteries with 25-30 minutes of flight time. This enhancement opens up diverse applications, including firefighting and locating missing persons using facial recognition capabilities.

He further stated, "By participating in this exhibition, we hope to promote a positive perception of the safety of hydrogen fuel cells, dispelling common misconceptions. We plan to continue the development of drone autonomous flight and control systems."

SWEET 2021, now in its 15th year, provides a platform for networking and substantial business opportunities for renewable energy companies in Gwangju, the center of the Energy Valley. The exhibition covers various renewable energy sectors such as solar, wind, bioenergy, hydrogen, and more.
