As one of the world's most innovative companies, Sunfire today develops and manufactures systems for renewable industrial gas and fuel production. These substitutes for mineral oil and natural gas, known as e-Gas, e-Fuel or e-Chemicals, replace fossil fuels in existing infrastructures. The solid oxide cells (SOCs) used for the conversion process are also used as generators to provide electricity and heat.

Sunfire’s vision is to make regenerative energy from sources such as wind farms, hydropower plants and photovoltaic systems available wherever and whenever it is needed — not just when the wind is blowing, the waves are crashing or the sun is shining.


The key component is the steam electrolyser, based on solid oxide cell technology and able to break water into its constituent parts not only from its liquid but also from its gaseous form (i.e. steam). The main benefit of steam electrolysis is that the enthalpy of vaporisation can be achieved without the use of expensive electrical energy. Indeed, recycling waste heat such as that generated by industrial processes makes it possible to increase the efficiency of the steam electrolyser to over 80 percent.


Sunfire is supported by strong partners such as Audi, Boeing or ThyssenKrupp Marine Systems. It is the company’s goal to refine the solid oxide electrolyser and fuel cell systems and to advance their industrialisation. Only then can Sunfire’s technologies be established as the cornerstones of a decentralised energy system of the future.
