Advancing Core Technologies
The facility aims to position Hyundai Motor at the forefront of global hydrogen technology through two key products:
- Next-generation hydrogen fuel cell: Hyundai Motor targets enhancing both power output and durability compared to current models while achieving price competitiveness to lead the global market. Fuel cells generate electricity through electrochemical reactions between hydrogen and oxygen, functioning as onboard power generators.
- PEM electrolyzers: The plant will produce high-efficiency polymer electrolyte membrane (PEM) electrolyzers as first production in Korea. These electrolyzers generate high-purity hydrogen from water without carbon emissions — a critical technology for achieving global net-zero targets. Drawing on nearly three decades of fuel cell development expertise, the company has achieved approximately 90 percent localization of electrolyzer components.
The company has already developed an electrolyzer stack and in February completed a 1 MW containerized electrolyzer system that is currently in demonstration operation, producing more than 300 kg of high-purity hydrogen daily. A 5 MW-class large-scale project is currently under development in Jeju, Korea, with the goal of establishing a complete green hydrogen ecosystem.
Advanced Manufacturing Platform
Hyundai Motor plans to operate the new Ulsan hydrogen fuel cell production facility as an advanced manufacturing platform incorporating core technologies from its accumulated human-centered manufacturing expertise.
The plant will extensively deploy robotics technologies to reduce worker strain while enhancing operational efficiency. Advanced monitoring systems will detect even minute safety hazards to protect workers.
Expanding the Hydrogen Ecosystem
The fuel cells produced will be optimized for different applications, from passenger vehicles to commercial trucks, buses, construction equipment and marine vessels.
Beyond fuel cells, Hyundai Motor Group is developing comprehensive solutions across the hydrogen value chain — from resource-circular production to storage, transport and utilization — while building partnerships with governments, global companies and research institutions.
The groundbreaking ceremony is expected to serve as a platform for collaboration among government, local authorities and industry stakeholders, reinforcing a unified approach toward accelerating the hydrogen economy. Hyundai Motor aims to strengthen its global leadership in hydrogen and expand strategic partnerships to support carbon neutrality and ecosystem development.
Attendees at the ceremony viewed multiple generations of fuel cells and electrolyzers, along with hydrogen-powered vehicles including the all-new NEXO SUV, trucks, excavators, vessels, tractors and forklifts — showcasing the extensive applications of hydrogen mobility.
The facility is expected to scale production in line with market growth, contributing to the expansion of the global hydrogen ecosystem and supporting infrastructure development.
At the ceremony, Hyundai Motor and Korean bus manufacturer KGM Commercial signed a Memorandum of Understanding (MoU) for fuel cell supply, highlighting the plant’s pivotal role in advancing Korea’s hydrogen ecosystem.
