Topsoe Confirms FID Will Build World’s Largest SOEC Electrolyser Plant; the company’s largest single investment

Topsoe’s board of directors made the final investment decision (FID) to begin construction of the world’s largest SOEC electrolyser manufacturing facility in Herning, Denmark. The plant’s manufacturing capacity is 500 MW per year with an option to expand to 5 GW.

SOEC technology consumes less electricity than alkaline and PEM technologies because the process requires less energy overall; with the integration of a steam supply, the SOEC process becomes even more efficient.

The case for using electrolysis to produce green fuels is now well established, but manufacturing capacity has always been the challenge. We are meeting this challenge head-on. We are committed to taking the lead in scaling power-to-x technology to contribute to the energy transition, and we are investing over DKK 2 billion [US$267 million] to meet this demand and address this fundamental weakness in supply. This is the largest investment in the company’s history, clearly underlining our commitment to driving the energy transition, and we hope this huge facility will serve as a catalyst for new investments in the future.

Sundus Cordelia Ramli, CCO of Topsoe’s Power-to-X division, said Topsoe already has 500MW of pre-sold capacity and is also in talks with other potential offtake partners.

With a capacity of 500 MW per year, the new facility will be the largest SOEC manufacturing plant in the world. This is a rapid acceleration not only for Topsoe, but also for Denmark.

Topsoe is also delivering on its REPowerEU ambitions when, in May 2022, a joint statement was signed with other industry leaders and the European Commission to commit to increasing European electrolyser manufacturing capacity tenfold by 2025.

This is a major statement of intent from Topsoe, but it is also a reality that industry cannot drive this energy transition alone. We expect long-term incentives and favorable framework conditions from the EU and the Danish government to continue accelerating the market for green hydrogen and anchoring large-scale electrolyser production right here in the EU.
