Hyundai Motor Group to Demonstrate 5 MW Hydrogen Electrolyzer, Accelerate Hydrogen Ecosystem Expansion

Participates in World Hydrogen Expo 2026
Presents Vision Spanning Hydrogen Production to Mobility
Builds Hydrogen Ecosystem in Saemangeum AI Valley

Hyundai Motor Group is building a hydrogen ecosystem spanning production, storage and transportation, and applications such as mobility.

The group plans to demonstrate a 5 MW-class electrolyzer stack module that produces hydrogen by electrolyzing water in Jeju in 2028. Following its hydrogen passenger car, the NEXO, it will also introduce mobility solutions using hydrogen commercial vehicles and railways.

Hyundai Motor Group unveiled its vision for hydrogen technologies, encompassing hydrogen production infrastructure, mobility, and ecosystem development, at World Hydrogen Expo 2026, which opened at KINTEX in Ilsan on the 4th. Jang Jaehoon, vice chairman of Hyundai Motor Group, visited the event that day, toured the group's exhibition pavilion and booths of key participating companies, and reviewed hydrogen-related technologies and business developments.

Hyundai Motor Group exhibited its polymer electrolyte membrane (PEM) water electrolysis plant technology and its Waste-to-Hydrogen (W2H) model for producing hydrogen from waste resources.

The group unveiled for the first time its approach to combining 12 water electrolysis stacks to form one 5 MW-class Electrolyzer Stack Module (ESM). One ESM can produce approximately 700 tons of hydrogen annually, enough to fuel a NEXO approximately 130,000 times. A key feature is that multiple modules can be arranged in parallel and scaled up to a water electrolysis plant with a capacity of several hundred megawatts.

Hyundai Motor Group operates a 1 MW-class containerized demonstration facility in Gwangju and is pursuing additional demonstration projects in Boryeong, Buan, and Jeju. In 2028, it will begin a 5 MW-class demonstration project in Jeju, and in 2029, it plans to pursue a water electrolysis plant project with a capacity of at least 20 MW in Saemangeum.

At its W2H exhibit, the group presented a resource-circulation model centered on HTWO Energy Cheongju that converts waste resources into hydrogen for local use. It also introduced hydrogen production and utilization projects tailored to local conditions, including a biogas-based hydrogen production facility in Paju and a project in Indonesia.

The group also showcased the 2027 NEXO, hydrogen commercial vehicles, and railway technologies. It unveiled for the first time a fuel cell system designed for greater durability to meet the demands of long-distance commercial vehicle operations. In the railway sector, it displayed a hydrogen electric locomotive model and a flat-type fuel cell module.

Hyundai Motor Group also introduced Bluelink Uptime Care, an integrated fleet management system that can precisely analyze vehicle data to support the operation of hydrogen commercial vehicles.

Centered on the Saemangeum AI Valley, Hyundai Motor Group presented a model for a future industrial city connecting renewable energy, hydrogen, AI (artificial intelligence) data centers, robotics, and urban infrastructure. The plan is to use electricity and hydrogen generated from renewable energy to power data centers and robot manufacturing plants, among other facilities.

A Hyundai Motor Group official said, "We will introduce the group's integrated hydrogen solutions, from hydrogen production to mobility and applications in urban and industrial sectors, while expanding opportunities to collaborate with customers and partners. Building on our hydrogen production capabilities, we will identify diverse applications and provide solutions optimized across the entire value chain, turning them into tangible businesses."
