Kassø

The Kassø e Methanol Facility in Tønder, Denmark produces e methanol using biogenic CO₂ sourced from a local biogas plant, 52.5 MW of Siemens Energy electrolyser capacity, and renewable electricity supplied by the adjacent Kassø Solar Park. The plant is designed for 42,000 tonnes per year of e methanol production across two methanol lines. The project reached major milestones in 2024 and 2025, including mechanical completion in June 2024, first green hydrogen production in January 2025, first raw e methanol production in March 2025, and official commissioning in May 2025. The facility is owned and operated through a joint venture between European Energy (51 percent) and Mitsui and Co (49 percent) under Solar Park Kassø ApS.
