## About

Based in Dresden, Germany, and founded in 2010 by CEO Nils Aldag and co-founders Christian von Olshausen and Carl Berninghausen, Sunfire SE develops and manufactures high-temperature solid oxide fuel cells for the generation of renewable electricity and heat using a wide variety of liquid and gaseous fuels. In March 2024, Sunfire GmbH raised EUR 100 million in venture debt funding from a European Investment Bank. The round was part of a larger EUR 315 million series E and venture debt funding.

Sunfire GmbH converts electrical energy into chemical energy and various liquid and gaseous fuels based on hydrocarbons like natural gas and liquefied petroleum gas (LPG) into electricity and heat. The company also offers products consisting of Sunfire hylink, electrolyzers for the production of renewable, low-cost industrial hydrogen, and Sunfire synlink, technology to produce renewable feedstocks for refineries such as for synthetic fuels, among other uses.

The company plans to use its proceeds from March 2024 funding to accelerate the growth and industrialization of its green hydrogen technologies.
