What are the regional incentives for converting to bioethanol?
This page is translated from the original post "Quelles sont les aides par régions pour une conversion au bioéthanol ?" in French.

Faced with the outrageous fuel prices at the pump, a solution exists: conversion to Bioethanol. Although the kits are expensive, there are fortunately aid programs depending on the region.
After a relative lull in pump prices, linked to discounts granted by the government and some oil companies, prices have significantly risen again and are not expected to drop much as long as the conflict between Russia and Ukraine persists. This is not the only factor driving up prices, as euro-dollar parity also influences fuel prices, not to mention the staggering taxes in France.
Therefore, you should expect to pay about €1.95 per liter of Super 95 at a large surface station in Yvelines (78), compared to €1.10 for a liter of E85 bioethanol, which is still well below its pre-crisis level, when it was more common to count on about €0.85/liter.
If you wish to install a bioethanol conversion kit, note that it will cost between €800 and €1,600 depending on your vehicle. This substantial sum can, depending on your place of residence, be mitigated by a regional subsidy. Here’s our France overview (source aide-sociale.fr):
