In an announcement Monday, Sunfire GmbH said Paul Wurth joined as the new lead investor through a Series C round of financing. 

With the injection of new capital, along with Paul Wurth’s technical support, Sunfire said it intends to move on industrial-scale projects that apply high-temperature electrolysis and Power-to-Liquid technology.

“Thanks to what is our largest financing round yet, we pave the way for the industrialization of our technology validated in pilot plants,” said Sunfire chief executive Carl Berninghausen. 

“With Paul Wurth joining the venture, we become a valuable partner for energy-intensive industries. This milestone means for us an important step towards an industrial company, and we will now be able to expand our pure product business to service activities also in the field of projects,” he added.    

Paul Wurth chief executive Georges Rassel said the investment arises from its effort to play a leading role in the steel industry’s transformation to carbon-free steel production. 

“We would like to accompany our customers also in their journey to hydrogen-based hot metal production and support them to achieve climate protection targets,” he said.
