LOTTE SK Eneroot is a South Korea–based energy company focused on hydrogen-based power generation. Formed as a joint venture between LOTTE Chemical Group and SK Gas, the company develops and operates hydrogen fuel cell power plants that supply low-carbon electricity and recover waste heat for industrial and local use.
Its projects typically deploy phosphoric acid fuel cell (PAFC) technology, using by-product hydrogen from petrochemical operations with a pathway to transition to clean hydrogen as supply scales. LOTTE SK Eneroot’s activities span project development, financing, construction, and operation, with installations located in industrial complexes such as Ulsan. The company contributes to Korea’s energy transition by adding distributed, carbon-free power capacity and integrating fuel cell systems into regional industrial ecosystems.
