Hyundai E&C Rallies Seven Partners To Design 100-MW-Class Electrolysis Plant

Hyundai Engineering and Construction (Hyundai E&C) is taking part in a government-funded research and development (R&D) project to develop design technology for water electrolysis plants of 100 MW or more. Korea’s Ministry of Climate, Energy and Environment is funding the work.

The project, titled “Front-End Engineering Design Technology Development for 100MW-Class Overseas Water Electrolysis Plant,” aims to produce a design package covering system configuration, process engineering, and operations, moving the technology toward demonstration and commercial deployment. Hyundai E&C leads a consortium that includes Hyundai Engineering, Hyundai Motor Company, Hanwha Global, Korea Midland Power, Future Standards Research Institute, Seoul National University, and Korea University. Hyundai E&C is developing the front-end engineering design (FEED) package and the feasibility analysis, using artificial intelligence and dynamic simulation to manage renewable energy fluctuations and improve plant stability.

Hyundai E&C says the water electrolysis sector is increasingly prioritizing renewable energy integration, standardized large-scale operations, and system optimization. The company’s relevant experience includes constructing a hydrogen production facility in Buan, Jeonbuk, and a 5 MW proton exchange membrane (PEM) water electrolysis system in Jeju.

The HMG Construction Technology Research Institute, the combined R&D organization of Hyundai E&C and Hyundai Engineering, is consolidating the group’s hydrogen capabilities across production, storage, transportation, and utilization. The institute is also researching small modular reactors, sustainable aviation fuel, offshore wind, and biogas.

“The results achieved through this R&D will serve as a key asset in strengthening our competitiveness in securing future water electrolysis projects in Korea and overseas,” said a Hyundai E&C official. “The HMG Construction Technology Research Institute, which is carrying out this project, will consolidate Hyundai Motor Group’s core technological capabilities across the entire hydrogen value chain, from production and storage to transportation and utilization, to establish a Korean-style green hydrogen platform, while further solidifying its leading position in the next-generation water electrolysis hydrogen business.”
