Topsoe has taken final investment decision (FID) to begin construction of the world’s largest SOEC electrolyzer manufacturing plant in Herning, Denmark. The plant will have a manufacturing capacity of 500 MW per year, with an option to expand to 5 GW. Construction is set to start in H2 2022.

Commenting on the announcement, Roeland Baan, CEO of Topsoe, said: “The case for using electrolysis to produce green fuels is now well established, but manufacturing capacity has always been the challenge. We are facing this challenge head on. We are dedicated to taking the lead on scaling power-to-x technology to help drive the energy transition, and we are investing over DKK 2 billion to meet this demand and address this fundamental supply weakness. This is the single biggest investment in the company’s history, clearly highlighting our commitment to driving the energy transition, and we hope this huge facility will act as a catalyst for new investment in the future.”

Sundus Cordelia Ramli, CCO of Topsoe’s Power-to-X division, added: “There is a genuine trust in us and our cutting edge SOEC electrolyzer technology, built on years of technological excellence. With this new state of the art manufacturing facility, we are taking power-to-x technology into a commercially competitive position, ultimately making the case for decarbonization unarguable. We already have 500 MW of pre-sold capacity and are in discussions with other potential offtake partners as well, who find our electrolyzer technology attractive, and look forward to being able to make more announcements in due course.”

At 500 MW capacity per year, the new facility will be the world’s largest SOEC manufacturing plant. This is a rapid acceleration not just for Topsoe, but also for Denmark and the EU towards a green energy transition while reducing dependence on fossil fuels.
