The plant will produce high-efficiency electrolysis stacks for industrial-scale green hydrogen production, marking the company’s single largest investment to date.
Initially designed for an annual production capacity of 500 MW, the facility has the potential to scale further. When operating at full capacity, it will enable up to 10 GW of installed electrolyzer capacity at customer sites worldwide, contributing to the reduction of an estimated 15 million metric tons of CO₂ per year – equivalent to the annual emissions of nearly 3.5 million passenger vehicles.
Roeland Baan, Chief Executive Officer of Topsoe, said: “Our SOEC facility will be a game-changer for the energy transition. The technology’s unmatched efficiency is pivotal for scaling green hydrogen production for industrial decarbonization. With this facility, we are moving SOEC technology and Power-to-X from ambition to reality – at a scale and speed that are urgently needed.”
Topsoe has already signed offtake agreements with First Ammonia for a green ammonia project in Texas, United States, and with Forestal for an e-methanol project in Spain. Both contracts include 10-year service warranty programs.
Spanning 23,000 square metres, the Herning facility integrates advanced automation, precision manufacturing, and materials science expertise under one roof. Topsoe’s SOEC stacks, proven for durability and high performance at its demonstration plant, will be deployed globally to support the production of green hydrogen and its derivatives such as e-fuels, ammonia, and methanol.
