Recently, Volkswagen of America made the announcement that it’s collaboration with Solazyme, Inc and Amyris, Inc for its Renewable Diesel Evaluation Program was successfully completed. Back in 2012 Volkswagen tested its renewable diesel formulas and TDI® Clean Diesel technology. The testing found that many of the results were very comparable to the crude based diesel in the performance category while resulting in fewer emissions. Throughout the two-year test over 134,000 miles were logged, evaluating the performance of a 100 percent algae based diesel fuel and a plant-sugar derived fuel, and it was also determined that fuel economy was either similar or even better.
“The successful completion of this collaboration with two leaders in renewable fuels and products highlights how far advanced fuel technology has come in recent years, proving that sustainable fuels are not only produced in more environmentally friendly ways but can offer similar performance and lower emissions from a well-to-wheel perspective when compared with commercially available crude based fuels,” said Ewald Goessmann, executive director, Volkswagen Group of America, Electronics Research Laboratory. “Evaluations like this are part of Volkswagen’s broader holistic environmental strategy which underscores the company’s commitment to the environment by deploying a comprehensive approach which addresses carbon reduction and sustainability at each part of the vehicle lifecycle.”
These results show just how promising renewable fuel can be, with benefits including better fuel economy and lower emissions. During the test, no engine problems were triggered and no extreme wear occurred and on top of that the production of soot was lower than using normal diesel.
Overall, the tests showed that renewable clean diesel could have extremely positive results and currently have a lot of potentials. Volkswagen plans to continue looking at the study to determine even more information for the future.
