Topsoe to Build Largest Electrolyzer Plant in Denmark

At a glance
  • Construction starts in the second half of 2022, with operations expected by 2024.
  • The plant will have an initial capacity of 500 MW per year, expandable to 5 GW.
  • The facility will produce SOEC electrolyzers, known for higher energy efficiency.
  • The plant will create 170 jobs and cover an area of 23,000 m2.

Project Overview

Topsoe is set to build the world's largest and most advanced industrial-scale electrolyzer production plant in Herning, Denmark. The facility aims to accelerate the green energy transition by providing Power-to-X solutions, particularly for hard-to-abate sectors such as transport, chemicals, steel, and cement.

Timeline and Capacity

Construction of the plant will commence in the second half of 2022, with operations expected to begin in 2024. Initially, the plant will have an annual capacity of 500 MW, with the potential to scale up to 5 GW, making it one of the first industrial-scale plants of its kind.

Technological Advancements

The facility will produce Solid Oxide Electrolyzer Cells (SOEC), which offer higher energy efficiency compared to competing technologies. This innovation is expected to play a crucial role in decarbonizing various industries and supporting the EU's ambitions for energy independence.

Economic and Environmental Impact

When fully operational, the plant will employ 170 people and cover an area of 23,000 m2. The project aligns with the recent agreement between the EU Commission and North Sea countries to significantly increase offshore wind capacity by 2050, ensuring the availability of renewable power for future Power-to-X facilities.
