Scania has announced that, after 20 years of providing ethanol
buses, the Swedish company (owned by Volkswagen
) is going to sell ethanol trucks from the next model year onwards. The marque also announced agreements to build a network of fueling stations to make it easily available for small businesses to buy the biofuel
. According to Scania's data, ethanol produced from sugarcane can reduce CO2
emissions by up to 90 percent compared to a regular diesel
engine. Scania stated that it's betting on ethanol because it's the most cost-efficient biofuel available.
What you might find interesting is that Scania's technology makes engines work according to the diesel principle (compression-ignition). This allow the engines to be as efficient as diesel units. Scania's ethanol contains 5-7 percent special additives that improve ignition and lubrication. Most current flex-fuel engines compatible with ethanol use the otto cycle with lower efficiency. Current ethanol-powered buses by Scania are already running in countries such as Norway, Spain, Italy, Poland, United Kingdom, China, Australia
