The analysis of life cycle ED95 fuel containing 95% ethanol produced from grape marc was conducted to better understand its environmental impact and find precisely the benefits of this renewable fuel.
The indicator of climate change reveals a reduction of more than 85% of greenhouse effect gas emissions through the ED95 in comparison to diesel.
Cycle analysis (LCA) to quantify the impact of a “product” from the extraction of raw materials up to the end of his life, through the phases of distribution and use or “production to consumption.” LCA enables the ED95 fuel now have dedicated expertise and a comparison with the diesel reference fuel in the transport of goods and people (trucks and buses).
The indicator reflecting climate change assesses the greenhouse gas emitted during the transformation process, but also during the manufacturing process inputs (natural gas, electricity, inputs, etc).
The large difference is explained by the carburetor, the two fuels emit CO2 from different backgrounds. ED95 for this CO2 is called “biogenic”, that is to say from the plant and is not counted in the indicator of climate change, while for fossil diesel, CO2 is original fossil and recognized.
Bioethanol, which represents 95% of the ED95, is developed by the cooperative Raisinor France from grape marc, raw material collected on radii from 50 to 200 km distilleries. These wastes from the production of wine are upgrading in the production of bioethanol and does not compete with food production. Production potential would be about 40 million liters of ethanol per year.
The marc is the set formed by the film, the seeds obtained from the pressing of the grapes after they have been separated from the wort. The pulp is ultimately the solid parts of the grape must as is the liquid part.
The positions of the Swedish company Scania, a pioneer in the development of sustainable transportation for bioethanol ED95 are quite clear.
The manufacturer who is campaigning for the traceability of the production of bioethanol, also wants to create a label that bioethanol production in conditions that respect the environment, people and territories. It also calls for appropriate taxation of bioethanol ED95 compared to current diesel, which takes into account the energy delivered and not the volume supplied.
From a regulatory point of view, today, fuel ED95 is considered an experimental fuel. “With a view to developing this greener fuel, ED95 must find its place in the official nomenclature of France authorized fuels (…) It will eventually benefit from a special tax recognizing its environmental interests,” says Scania. It even says ready to propose its solution on the French market.
1986 – Scania piloting buses bioethanol ED95 urban services in cooperation with the regional public transport company in Stockholm. Therefore, Scania ethanol buses are used in the Swedish capital. To date, more than 900 Scania ethanol buses are in operation worldwide.
1995 – the first hybrid concept bus.
2007 – Testing an ethanol Monaco bus.
2009 – Six hybrid buses begin full-scale tests in Stockholm.
April 2011 – Test bioethanol ED95 bus to St-Quentin (02).
September 2011 – Test bioethanol ED95 in Reims (51) bus.
October 2011 – Test three distribution trucks bioethanol ED95 in the STAF carrier in Villeneuve-le-Roi.
