Lyngby/Denmark – With the new facility, Topsoe will accommodate the rapidly increasing demand for competitive electrolysis technology, predominantly for green hydrogen plants based on renewable electricity. Development of the automated manufacturing facility, that will be the largest of its kind, is ongoing. Construction will commence in 2022 in order for the facility to be operational by 2023.

“This new manufacturing facility is a concrete step to take a leading role in the ongoing energy transition towards a low carbon future. We strongly believe that one of the most viable routes to this goal lies in the efficient utilization of renewable electricity to produce green hydrogen, fuels, and chemicals. With Topsoe’s solid oxide electrolyzer cell (Soec), more than 90 % of the renewable electricity that enters the electrolyzer is preserved in the green hydrogen it produces. This is significantly more efficient than the other available technologies in the market. Topsoe already has a number of technologies and several others under development that will ensure that the company will play a leading role in energy transition, reducing carbon emissions world-wide. The decision to build this large-scale production of our Soec technology shows that we are willing and able to translate our ambition into reality,” says Roeland Baan, CEO of Haldor Topsoe.
