Fossil fuels provide a constant and reliable energy supply. We want to have our energy sources available at any time when we want it or need it. A substitution technology therefore also needs to be constant and reliable, next to its scalability to live up to the full energy demand.
Renewable electricity can also be transformed into synthetic liquid e-fuels. Again, the first step is to produce hydrogen by splitting water H2O into H2 and O2 through electrolysis. Thereafter comes the synthesis of hydrogen via the Fischer-Tropsch process by adding CO and CO2. This process is a collection of chemical reactions that converts a mixture of carbon monoxide, carbon dioxide and hydrogen into liquid hydrocarbons. The result is synCrude, resembling fossil crude oil. From there one can produce a number of hydrocarbon fuels, as diverse as synthetic e-diesel, e-gasoline, e-methanol or e-kerosene.
