The fuel cell and water electrolysis unit of HD Hyundai, HD Hydrogen, has developed a mass production system for Korean-style SOFC – solid oxide fuel cells and is entering the market on a full scale.
HD Hydrogen stated on August 7, 2026, that it just finished pre-use assessment of its SOFC power generation equipment HD250 and HD300 as well as manufacturing facilities from the Korea Electrical Safety Corporation, creating a product mass production system.
The company was founded in August 2024 and developed SOFC power generation equipment with high efficiency, and along with it, constructed a production line in a matter of two years.
Interestingly, HD250 and HD300 are now mass-produced, small- and mid-size power generation SOFC products of 249kW-class and 285kW-class, respectively, for which demand from the market is pretty high. The water-free operation technology, which can operate without an additional external water supply, improves the ease of installation and the effectiveness of operation, and makes the products suitable for different installation settings and operating conditions.
The Korean-style SOFC is known as a next-generation power generation technology that can realize high generation efficiency within the hydrogen fuel cells. It can be used with a variety of fuels such as hydrogen and natural gas and can additionally employ the heat generated in the power generation process and thereby is attracting focus as an essential technology when it comes to eco-friendly distributed power.
HD Hydrogen aims to target the domestic eco-friendly small-scale power plant market initially and to get into the self-consumption power market for energy-intensive facilities, including data centers. In addition, the company will accelerate development of high-output and high-durability SOFC products for ships, thereby expanding its scope of operations into global distributed power generation as well as environmentally friendly energy markets.
According to Nam Young-jun, the CEO of HD Hydrogen, “The background to being able to complete product development and establish a mass production system in a short period after our founding lies in the manufacturing capabilities HD Hyundai has accumulated. Using this mass production system as a springboard, we will actively expand our SOFC business not only in the onshore power generation market but also in the maritime market going forward.”
