Fuel of the Future? What Drivers Need to Know About E20

A new fuel is intended to help reduce CO2 emissions in road traffic – without the need for new vehicles.

Since autumn 2023, a test operation with Super E20 has been running at a gas station in Mannheim. The fuel contains up to 20 percent bioethanol – twice as much as E10. The goal is to reduce the emissions of the existing fleet of combustion vehicles, of which over 40 million are on the road in Germany alone.

Higher Bio Content, Lower Emissions

E20 is currently being used as part of a fleet test, including by Südzucker AG. According to information from ADAC and industry partners like CropEnergies, significant CO2 savings could be achieved through the higher blending of bioethanol – depending on the production method, even up to 80 percent compared to pure gasoline. In combination with bio-naphtha, savings of up to 40 percent in the end product are possible.

Legal and Technical Questions Unresolved

So far, the European fuel standard only allows an ethanol content of ten percent. New standards would be necessary for the official approval of E20. Technically, the use is also not without problems: While many modern gasoline engines could handle E20, experts warn of possible damage to older models, such as the fuel pump or injection system. Additionally, consumption could slightly increase by around three percent.

Political Debate on Approval in Germany

CDU Members of the European Parliament have appealed to EU Commission President Ursula von der Leyen. Their argument: Given the slow spread of e-mobility, the existing vehicle fleet must also be considered. E20 could be a quick lever for CO2 reduction – provided there are standards and comprehensive infrastructure.

Not a Replacement for E-Mobility, but a Transition

E20 is not considered a final solution, but rather a transitional solution within the framework of the energy transition. It is intended to help reduce emissions in the transport sector until alternative drives gradually replace the combustion fleet. When and if E20 will be available nationwide depends on regulatory requirements, manufacturer approvals, and acceptance by drivers.
