Korea South-East Power (KOEN) and the Saemangeum Development Agency have signed a memorandum of understanding to develop a large-scale green hydrogen complex in Saemangeum, South Korea. The proposed project will integrate solar power generation, green hydrogen production and hydrogen-fired power generation in Buan, North Jeolla Province.
Furthermore, the project is planned for 1 GW of onshore solar capacity with 320 MW of water electrolysis capacity and 100 MW of hydrogen-only power generation. The project will feature a power-to-gas-to-power system, using solar electricity to produce, store and later reconvert green hydrogen into electricity. KOEN aims to connect the project to South Korea’s clean-hydrogen electricity market, which has set 2026 clean-hydrogen power procurement at 500 GWh.
In March 2026, Samsung C&T’s Engineering & Construction (E&C) Group completed an off-grid green hydrogen production facility in Gimcheon, South Korea. The plant generates green hydrogen using entirely renewable energy sourced from an 8.3 MW solar power installation. With a 10 MW water electrolysis system, the facility is capable of producing around 0.6 tonnes of green hydrogen per day, translating to over 230 tonnes annually.
