High-performance electrolysis

There are three common industrial technologies for producing green hydrogen through electrolysis: high-temperature SOEC, low-temperature alkaline, and low-temperature proton exchange membrane (PEM). 

Only SOEC uses water in the state of steam. The breakdown of the steam takes place within the SOEC cell, where it is split via reduction into a green hydrogen molecule and oxide ions (O2-). The oxide ions are then transported through the electrolyte to the anode and oxidized into oxygen molecules. 

One significant benefit of choosing SOEC is its high efficiency compared to alternative technologies. This efficiency, achieved by leveraging high-temperature electrolysis, ultimately makes it possible to produce more hydrogen per unit of power. 

Our SOEC technology leverages high-temperature electrolysis, producing more hydrogen per unit of power compared to traditional alkaline and PEM methods.

This is achieved through faster reaction kinetics and optimized conductivity, resulting in higher efficiency and lower power consumption.

With our SOEC, renewable electricity is utilized optimally to produce green hydrogen efficiently. This results in more efficient and carbon-free processes for Power-to-X solutions.

We are constructing the world’s first industrial-scale SOEC manufacturing facility in Herning, Denmark.

Set to begin operations in 2025, this 500 MW plant is backed by a EUR 94 million grant from the EU Innovation Fund, which vets the project and serves to mitigate potential risks in getting our SOEC technology to market.

The Herning facility will produce cutting-edge SOEC stacks, driving Europe’s green hydrogen goals and reducing CO₂ emissions by approximately 7.5 million tonnes over the next decade compared to conventional hydrogen production methods.
