Haldor Topsoe: SOEC technology can unlock full potential of renewable power

Haldor Topsoe says solid oxide electrolysis cell technology (SOEC), a core technology in power-to-X solutions that produce climate-friendly fuels such as hydrogen and ammonia, holds the key to unlocking the full potential of renewable power.

The SOEC technology can be thermally integrated with a range of chemical synthesis processes enabling the efficient production of future fuels such as methanol and ammonia.

Green ammonia, for example, can be produced from air, water, and renewable electricity and become a highly attractive fuel for decarbonising the maritime sector

“In the article in Science, we claim that the SOEC technology holds the best promise for a wider adoption thanks to unrivalled energy conversion efficiencies,” said Rainer Küngas, Principal Scientist at Topsoe and one of the lead authors of the article.

“The high operating temperature of SOECs gives rise to the two main advantages over competing alkaline and polymer-electrolyte membrane (PEM) electrolysers: more favourable thermodynamics and faster kinetics.”

“It is also essential that the SOEC technology is based on scalable production methods and abundant raw materials such as nickel, zirconia, and steel.”

In the article, Haldor Topsoe argues the technology is ready for an industrial scale-up, which is already happening at a rapid pace.

The technology has moved from the R&D phase into demonstration and scale-up, and today it is on the verge of commercialisation.

Haldor Topsoe is at the forefront of the commercialisation activities and has just shipped the world’s first unsubsidized SOEC plants that will soon start converting CO2 into useful chemicals in Ohio, US.
