Impact Rating




Converting captured CO₂ into renewable gases and liquids.
Company Overview
Sunfire is on a mission to replace fossil fuels by converting captured CO₂ into renewable gases and liquids. Their technologies, including high-temperature SOEC and alkaline electrolysers, facilitate the production of renewable hydrogen and syngas, aiding industries in decarbonising various production chains.
Sunfire's Impact
Over decades, we have been excessively consuming coal, crude oil and natural gas, releasing billions of tons of CO2 into the atmosphere which in turn has led to detrimental effects on the planet. Sunfire’s mission is to replace these fossil fuels with renewable energy to prevent any further damage.
Current Investors
Current investors include Amazon, Lightrock, Hydrogen One Capital, The Climate Pledge, Carbon Direct, Eurazeo, Iven Capital, Electranova Capital and many others.
Goldman Sachs Bank Europe SE served as exclusive financial adviser and placement agent to Sunfire.
Sunfire's Growth Strategy and Use of Funds
Sunfire has recently announced plans to scale its alkaline electrolysis business, building a large-scale electrolyser production site in Germany with an annual manufacturing capacity of 500 MW by 2023 – with a further extension to gigawatt-scale already in planning.
These new funds will allow Sunfire to bring its advanced pressurised alkaline and game-changing solid oxide (SOEC) electrolysis technologies to industrial scale, building the first in a series of production gigafactories, creating both meaningful electrolysis capacity for our customers and attractive returns for our investors.
Risks Associated with Sunfire
Several challenges associated with the energy transition can be managed by coupling the sectors of electric power and mobility. Green power could be stored in the long term and fuels of high energy density could be used in a carbon-neutral way.
The first litres of fuel were produced from air-captured carbon dioxide and green power having implemented a continuous process with maximum carbon dioxide utilization and very high energy efficiency.
How are Sunfire driving innovation?
With its efficient high-temperature electrolysis, Sunfire already contributed to the breakthrough of a promising and innovative technology in the past. Sunfire is now implementing it on a multi-megawatt scale in industry. In addition, the company successfully supplies numerous customers with its robust pressurized alkaline technology to meet the immense demand for green hydrogen.
