• E-Fuel

    The renewable fuel


Net-zero transportation

Today, the global transportation sector meets more than 90% of its energy demand with the combustion of fossil fuels. While e-mobility and fuel cell solutions can effectively decarbonize urban and medium distance transportation, existing vehicles as well as airplanes, vessels, and truck fleets will continue to rely on fuels for the decades to come.

Renewable synthetic fuels (“e-Fuel”) produced from captured CO2 and water substitutes fossil-based gasoline, diesel and jet fuel, and effectively reduces transportation emissions.


The superior production pathway for e-Fuels is the Power-to-Liquid (PtL) process. Using proprietary PtL know-how, game-changing SOEC based co-electrolysis technology and advanced Fischer-Tropsch reactors, Sunfire has developed a fully integrated solution to produce e-Fuels.

In a first step, Sunfire-SynLink electrolyzers convert CO2, water steam and renewable electricity into renewable syngas, a mixture of hydrogen and carbon monoxide. In a Fischer-Tropsch synthesis, syngas is then processed into a renewable, synthetic crude – a sustainable substitute for crude oil. This renewable crude can be refined into different blends of e-Fuel such as jet fuel, diesel, gasoline and other hydrocarbon fuels.

Process e-Fuel production

Core advantages

+ Carbon-neutrality: By utilizing CO2 that has been previously released, Power-to-Liquid closes the carbon cycle

+ Electrical efficiency: Reusing heat and off-gas from the Fischer-Tropsch synthesis for co-electrolysis (Sunfire-SynLink) reduces electricity demand

Infrastructure integration: Due to similar chemical properties as crude oil, renewable crude can be processed in existing refinery infrastructures

Product quality: The use of pure feedstocks leads to a superior quality of e-Fuel compared to fossil fuels, e.g. no sulphur content, reduced NOX emissions

Scalability: PtL can be used to produce a wide variety of end-products that enable decarbonization transportation

e-Fuel is the sustainable solution for the aviation, maritime, and road transport. It will make a major contribution to the decarbonization of transportation across the globe, without requiring adaptions of existing fleets.

e-Fuel for Aviation


Today, airlines consume massive amounts of fossil jet fuel to move people around the globe, emitting hundreds of million tons of CO2 per year. e-Fuel will enable climate-neutral flying by utilizing captured CO2 and water as feedstocks to produce a fully renewable jet fuel. The global jet fuel certification scheme ASTM already accepts a blending of 50 % e-Fuel with conventional kerosene. Thus, e-Fuel can be used in every airplane – already today.

e-Fuel for logistics and cruises


Despite a rapid expected increase in global trade, logistics and cruises, the shipping industry aims at reducing GHG emissions by 50 % until the year 2050. To meet climate targets, e-Fuel produced from captured CO2, water and renewable electricity is key to effectively reduce carbon emissions of vessel fleets – without requiring high investments to switch propulsion technologies.

e-Fuel for road transport

Road Transport

Alongside e-mobility and fuel cell solutions, e-Fuels are key to swiftly decarbonize existing car and truck fleets and to enable climate-neutral long-haul transportation. e-Fuels perfectly integrate into well-established infrastructures throughout the world – without requiring major investments into new propulsion technologies and fueling equipment.

Current Projects

Sunfire realizes end-to-end PtL-projects with strong partners. Norsk e-Fuel is our first flagship project and more are already under development.


Norsk e-Fuel is the world’s first industrial-size demonstration of the Power-to-Liquid process. Using Sunfire-SynLink electrolyzers and direct air capture technology, the project converts Norway’s extensive renewable electricity resources into 10 million liters of renewable jet fuel per year.
