ED95 reduces emissions from heavy goods transports

Nearly all heavy goods vehicles are run on diesel, a fuel that has a negative impact on our climate, the local environment and people’s health. SEKAB has developed ED95, an ethanol fuel that reduces emissions of fossil CO2 by up to 80 per cent. Additional benefits are near-zero particle pollution and low nitrogen oxide (NOx) emissions.

ED95

Heavy goods transports are powered almost entirely by diesel, causing emissions of greenhouse gases and other pollutants. The efficient transport of goods and people is absolutely essential in our society, but the substantial environmental impact of transports must somehow be reduced. The solution SEKAB has worked with for 20 years is called ED95.

ED95 is an ethanol-based fuel for customised diesel engines. Ethanol’s potential can be utilised up to 40 per cent better in a diesel (compression ignition) engine than in a petrol (Otto) engine. With ED95, energy efficiency is as high as in diesel-powered engines, making it the best technique for ethanol.

Over the past 40 years, heavy goods road transport has increased nearly 30 per cent – a paradox considering that the volume of goods transported has actually decreased. It seems that goods are transported farther and less efficiently today than in the past, and some goods previously transported by rail and sea are now transported by lorries, which is worse for the environment. According to EU forecasts, freight tonne kilometres (FTK) will increase by a total of 50 per cent between 2010 and 2030, and the proportion of heavy goods transports is expected to increase from 73 to 77 per cent.

Scania’s ethanol buses have been running since the 80s

Scania has extensive experience with ethanol engines, having produced its first in the early 1900s. The first real ethanol diesel was produced in the mid 80s in conjunction with Stockholm Local Transport’s initial shift towards renewable fuels.

The first ethanol-powered buses were on the roads in Örnsköldsvik, Sweden in 1986, when the technology was refined through collaboration between SEKAB and Scania. Today, ED95 consists of 95 per cent ethanol and five per cent additives that lubricate and protect against corrosion and improve engine ignition.

ED95 provides all the advantages of ethanol

Today, nearly a thousand ED95 buses are in operation around the world, and the technology is established and appreciated. There are many benefits of ethanol-powered buses and lorries:

  • Ethanol is the world’s most prevalent biofuel and can be produced in large quantities and in many countries
  • Ethanol diesels meet emissions standards for hazardous particles without requiring particle filters
  • Comparatively low health effects that are relatively easy to manage
  • A diesel engine utilised ethanol’s energy 40 per cent better than a petrol engine
  • An ethanol diesel is just as efficient as a conventional diesel engine
  • ED95 emits up to 80 per cent fewer climate-changing CO2 equivalents than diesel
  • The most recent Scania ethanol diesels are certified under the most stringent emissions standards: Euro V and EEV
  • Substantially lower nitrogen oxide and hydrocarbon emissions than in diesel engines

ED95 can be produced locally

Biofuels and increased energy utilisation efficiency are not enough to tackle transport sector climate emissions. We must also reduce the total transport volume. It is therefore highly advantageous that ED95 can be easily made from locally-produced ethanol. SEKAB is also involved in discussions on the licensed production of ignition improvers, which can be used to further reduce the need for transports.
