An independent study for T&E assesses the near-term cost of e-petrol production for cars.
E-fuels have entered the political debate on car CO₂ standards as a decarbonisation alternative to electric vehicles. To establish an up-to-date evidence base that can better inform ongoing policy discussions, T&E commissioned consultancy Ionect to assess the technical feasibility and near-term cost of e-petrol production for cars.
The study finds that producing e-petrol in 2030 would cost around €4 per litre. At the pump, this would translate into fuel prices of roughly €7 per litre, compared to less than €2 per litre for fossil petrol. At such prices, e-petrol would be unaffordable for most drivers, especially when electric mobility offers a much cheaper alternative.
Proponents of e-petrol for cars say that some e-fuel production co-products are unavoidable, and that once the aviation sector scales up e-fuels, these co-products could become cheap and widely available for road transport. Ionect’s findings challenge this narrative. The study concludes that producing e-petrol derived from aviation e-fuel co-products would actually be even more expensive than dedicated e-petrol production. Moreover, T&E estimates that any potential e-petrol co-product volume would amount to less than 3% of the fossil petrol consumed by European cars in 2035. Crucially, the study also finds that co-products from aviation e-fuel production can be avoided entirely, at a relatively modest additional production cost of around 10%. Alternatively, any co-products could be directed to the chemicals sector, including plastics.
Overall, there is no credible case for using e-petrol in cars: volumes would be minimal, they do not reduce tailpipe air pollution, and electric mobility offers a much more affordable alternative. The European Commission proposed to include a compensation mechanism for fuels in the car CO₂ regulation which would reward carmakers with lower CO₂ targets for the biofuels and e-fuels that are placed on the market by fuel suppliers. T&E strongly recommends that co-legislators delete the proposed fuel credits mechanism as it would only increase the costs of decarbonisation for both industry and drivers, and delay the inevitable transformation towards affordable electric mobility.
