Hylium Industries

What Hylium Industries does

Hylium Industries, Inc. is a South Korean cryogenic liquid hydrogen (LH2) technology company founded in 2014 by CEO Dr. Kim Seo-young, who spent 20 years researching liquid hydrogen at KIST before commercialization. Headquartered in Pyeongtaek (8,264 m² facility, 4,958 m² floor area) with R&D offices in Seoul and Sacramento and a European branch in Essen, Germany, the company offers an integrated LH2 stack: compact liquefaction systems, ultra-light titanium storage tanks (3L–6,000L), transport cylinders and trailers, mobile hydrogen refueling stations (mHRS), and LH2-powered fuel cell drones including the HyliumX (5+ hour flight time, 90km+ range) and Dodeca (12-rotor). Proprietary technologies include VCS boil-off reduction (<4%/day) and Korea's first domestically developed LH2 pump.

The company monetizes through four primary streams: direct hardware sales (LH2 tanks, trailers, refueling stations, drones) to government, military, and enterprise customers; technology licensing via the Element 1 Corp Strategic Assembly License Agreement; Hydrogen-as-a-Service drone operations primarily in the US market; and thermoelectric device (TED) sales for automotive thermal management. Customers include Hyundai Motor and POSCO (also Series A investors), KSOE/HD Hyundai, SK E&S, the Republic of Korea Army (Ami Tiger Drone Unit), Jeju Province Government, and NEOM in Saudi Arabia. Marketing combines enterprise field sales targeting large industrial and government buyers with active participation in global hydrogen and drone exhibitions (World Hydrogen Expo, H2 MEET, Drone Show Korea). Distribution leverages direct enterprise sales, strategic partnerships (Chart Industries JV Hylium Chart for trailers, Element 1 Corp for licensing), and a minor e-commerce shop for SMB/consumer channels. The company has received the WEF Technology Pioneer 2025 designation and Korea's Industrial Medal of Honour.
