NREL Survey Shows Dramatic Improvement in B100 Biodiesel Quality

17.04.2013
The latest national survey of 100% biodiesel (B100) "blend stock" samples by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications.
The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers – along with reliable operation of the nation’s vehicles powered by biodiesel blends.

“The survey showed a major improvement over results from previous years,” NREL Senior Chemist Teresa Alleman said. “In our 2007 survey of B100 biodiesel, less than half of the samples met quality specifications. More stringent quality requirements, along with the voluntary BQ-9000 quality management program, are among the reasons for this marked improvement.”

B100 is not commonly used as a fuel, but is blended with petroleum diesel, typically in blends up to 20%, and has been part of the industry's steady growth in the past decade. B100 production increased from 27.9 million gallons in 2004 to more than 1 billion gallons in 2012.

For the most recent survey conducted from August 2011 to February 2012, NREL researchers collected fuel samples from 53 producers and 14 terminals from across the United States. Terminals from the East and West Coasts, the Rocky Mountain region, and the Midwest were tested for a range of critical properties, such as free and total glycerin content, metals content, and cloud point that could have an immediate impact on operability.

To ensure product quality, ASTM published the first B100 quality standards in 2002. ASTM International does not enforce fuel quality, but it is a leader in the development and delivery of international voluntary consensus standards. Its specifications are frequently adopted by state and local governments to ensure fuel quality and are monitored by industry members. NREL is among the organizations participating in the development of standards.

The anonymous data from the NREL study "Quality Parameters and Chemical Analysis for Biodiesel Produced in the United States in 2011" are in publication and available on NREL’s website for use by interested parties.

NREL is the U.S. Department of Energy's primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for DOE by the Alliance for Sustainable Energy, LLC.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
