How are e-Fuels produced?
Fischer-Tropsch synthesis is a chemical process in which a mixture of carbon monoxide (CO) and hydrogen (H₂), commonly referred to as synthesis gas, is converted into various hydrocarbon compounds of different chain lengths. Components that are liquid at room temperature can be used as fuels, while solid components can be used as waxes.Learn more
An electrolyser is a device or system that uses the process of electrolysis to split water (H₂O) into its components hydrogen (H₂) and oxygen (O₂) using an electric current.Learn more
Methane pyrolysis is a chemical process in which methane (CH4), the main component of natural gas, is broken down into its components hydrogen (H₂) and solid carbon at high temperaturesLearn more
Hydrogenation is a chemical process in which hydrogen molecules (H₂) are added to unsaturated compounds, usually in the presence of a catalyst, to produce saturated compounds.Learn more
Derived from naturally occurring and renewable sources that are not depleted during use
Renewable energy is energy that is obtained from naturally occurring and renewable sources that are not depleted during use. These sources include sunlight, wind, rain, tides, waves, geothermal heat and biomass.Learn more
Synthesis gas is an important gas mixture that consists mainly of carbon monoxide (CO) and hydrogen (H₂) and, as the name suggests, is used for syntheses. It is traditionally produced using various processes in which carbon-containing starting materials such as fossil fuels, biomass or waste materials are converted into a gas mixture. Synthesis gas is produced from H₂ and CO₂ in connection with power-to-liquid or for the production of e-fuels.Learn more
Where doe e-Fuels come from?
The term "renewable raw materials" in the context of e-fuels (electric fuels or synthetic fuels) refers to sustainable and non-fossil carbon sources that are used as feedstock for the production of synthetic hydrocarbon fuels through a combination with renewable electricity.Learn more
The term "carbon neutrality" in the context of e-fuels refers to the fact that the total carbon dioxide (CO₂) emissions generated during the entire life cycle of the production, use and ultimate consumption of e-fuels are offset by a corresponding amount of CO₂ that is removed from the atmosphere or prevented from being released in order to produce the e-fuels.Learn more
Power-to-liquid (PtL) is a process in which electricity generated from renewable sources is used to produce hydrogen by means of electrolysis.Learn more
Methanol is mainly produced through methanol synthesis, in which carbon monoxide and hydrogen react at high temperatures and pressures.Learn more
Hydrogen and e-fuels are both capable of enabling CO₂-neutral mobility.Learn more

Decarbonization is a complex and compelling process that aims to reduce the concentration of carbon dioxide (CO₂) and other greenhouse gases (GHG) in the atmosphere.Learn more
E-fuel blending refers to the mixing of synthetic fuels, also known as electric fuels or e-fuels, with conventional fossil fuels in order to reduce the carbon emissions of the overall fuel mixture.Learn more
Emissions trading (ETS) is a climate policy instrument in which companies receive a limited quota of emission allowances that they can trade with each other.Learn more

Alternative fuels for aircraft include synthetic fuels produced from renewable resources or carbon dioxide and hydrogen.Learn more
What e-Fuels really are?
E-fuels have emerged as a potential solution for energy storage, for solving the temporal and local difference between renewable energy production and its consumption, and for the seamless continued use of existing means of transportation and logistics infrastructure. In terms of sustainability, e-fuels therefore offer a unique mix of ecological, social and economic benefits.Learn more
A carbon footprint is a measure of the total amount of greenhouse gases, primarily carbon dioxide (CO₂), and other related emissions that are directly or indirectly associated with a person, organization, event, product or activity.Learn more
