Bio MCN uses an innovative technology to convert glycerin into high-quality bio-methanol on a large industrial scale. As a fuel, bio-methanol can either be blended with petrol, or it can be used as a feedstock for providing other environmentally friendly fuels. At Ecofys we determined under what conditions methanol can be used in petrol engines, and how its use affects vehicle emissions.
The emission tests were performed on a 2007 model SAAB 9-5 bio-power vehicle with a manual gearbox. This car - a standard flexi-fuel car designed for use with petrol and E85 alcohol fuel (or any mixture of the two), - was not optimised for methanol. All regulated emissions remained well below Euro 4 emission standards on a range of mixtures of methanol.
The engine runs more efficiently on M85, resulting in lower emissions of CO2 compared to petrol and E85 (up to 15% lower compared to petrol)). Using bio- methanol further reduces overall emissions as it is produced from renewable feedstock derived from organic waste materials and crops other than those used for food consumption.
