What Hogreen Air Co. does

Hogreen Air Co. (주식회사 호그린에어) is a privately held South Korean hydrogen mobility company founded in September 2016 by CEO Hong Seong-ho (홍성호) and headquartered in Buk-gu, Gwangju. The company designs and sells hydrogen fuel cell power systems, unmanned aerial vehicles, and hydrogen storage/handling equipment for industrial, defense, government, and commercial customers. Its core hardware includes gaseous- and liquid-hydrogen drones offering 2+ hours of flight time (up to 5 hours for liquid hydrogen and up to 14 hours with the 4.8kW power pack) versus 20–30 minutes for lithium-battery drones, hydrogen power packs (A zero 2.4kW, A1 4.8kW) built around Intelligent Energy IE-SOAR fuel cells, SPACE ENERGY SP-100 stationary generators, IE-DRIVE 100kW fuel cells, and Type 3 gaseous (6.8L/9.2L) and vacuum-insulated liquid (6L/16L) hydrogen containers plus liquid-hydrogen converters and sensors.

Technically, the company combines self-designed hydrogen fuel cell power packs with an LTE/5G mobile-network-based Ground Control System (GCS v4.1) that enables remote/cross-border drone operation, OTA updates, LiDAR-based obstacle visualization, SLAM autonomous flight, multi-drone formation control, and AI video analysis. AI-driven mission capabilities—face recognition, license-plate detection, 3D mapping, crack/pipeline/bridge inspection, and smoke/wildfire detection—are delivered partly through partners (NetOn for facial recognition, Capturing Reality for photogrammetry). The company holds exclusive Korean distribution and domestic licensing rights for UK-based Intelligent Energy fuel cells and has filed/registered approximately 20 patents.

Commercially, Hogreen Air operates a B2B enterprise field-sales motion focused on defense, government, industrial, and energy sectors, supplemented by public procurement (innovation-product designation), an inquiry-based customized quotation system, a Naver Smart Store, and a subscription GCS software service. Revenue is predominantly hardware/component sales (products currently sold as components rather than finished units), with additional subscription and professional-services streams. Reported revenue was roughly 2.6–3.1 billion KRW annually across 2021–2024 (2023: ~2.9 billion KRW). The company employs 18 people, over half in its corporate research institute.
