Samsung C&T has completed Korea’s first off-grid green hydrogen production facility powered exclusively by renewable energy.
The company announced on March 25 that it completed a green hydrogen production facility in Gimcheon, North Gyeongsang Province, linked to solar power generation. Attendees at the completion ceremony included Minister of Climate, Energy and Environment Kim Sung-hwan, lawmaker Song Eon-seok, North Gyeongsang Province Deputy Governor for Economic Affairs Yang Geum-hee, Gimcheon Mayor Bae Nak-ho, Daegu Regional Environment Office Director Cho Eun-hee, Korea Institute of Energy Technology Evaluation and Planning President Lee Seung-jae, Korea Hydrogen Union Chairman Kim Jae-hong, and Samsung C&T Construction Group CEO Oh Se-chul. This attendee list and event framing are also reflected in English-language coverage. 
This project uses 100% renewable energy generated by an 8.3 MW solar power system to produce green hydrogen through water electrolysis, with a 10 MW hydrogen production setup. The facility can produce 0.6 tons of green hydrogen per day and more than 230 tons annually. The hydrogen produced will be connected to local hydrogen infrastructure and supplied to facilities such as hydrogen vehicle charging stations. 
The project is significant because it is Korea’s first case of applying an off-grid model that produces hydrogen by directly using renewable energy without relying on the external power grid. In that sense, it presents a model for renewable-energy-based green hydrogen production. Samsung C&T says that, based on the experience gained through this project, it plans not only to lay the foundation for future overseas green hydrogen projects, but also to promote localization of water electrolysis equipment and operating technologies, which have been designated as national strategic technologies. 
In this project, Samsung C&T carried out the overall EPC scope, including design, procurement, and construction of the solar power facilities, water electrolysis equipment, and hydrogen production and storage systems. The company also plans to participate in future operations and maintenance in order to ensure stable facility operation and continue advancing the technology. 
Jeong Gi-seok, head of Samsung C&T’s Renewable Energy Technology Research Center, said, “By realizing Korea’s first off-grid green hydrogen production, we have secured the technological foundation for pursuing large-scale green hydrogen projects both domestically and internationally.” He added that the company plans to continue strengthening its competitiveness in the global green hydrogen market based on eco-friendly energy technology and business capabilities.

Meanwhile, Samsung C&T’s construction division considers green hydrogen and ammonia to be key pillars of its future eco-friendly energy business and is pursuing related projects in global markets including the Middle East and Australia. In Korea as well, the company is expanding its business across the broader green hydrogen value chain, including participation in hydrogen and ammonia storage and supply infrastructure projects. Samsung C&T’s broader green hydrogen and ammonia push has also been described previously by official and industry reporting.
