Biodiesel Fuel Quality More Accessible Than Ever

By The National Biodiesel Board | April 15, 2020

Biodiesel fuel quality information is more accessible than ever thanks to new reports being published from the National Renewable Energy Laboratory. Through funding and support from the National Biodiesel Board, NREL’s statistical analysis is based on thousands of data points previously unavailable.

“Never before has NREL been able to provide this level of fuel quality information,” said Teresa Alleman, senior fuel chemist for NREL. “By partnering with NBB’s National Biodiesel Accreditation Commission, BQ-9000, we now have a simpler, more efficient way to collect, analyze and determine the quality of biodiesel. These reports will act as a recurring insight into biodiesel fuel quality each year.”

The reports are comprised of data gathered from U.S. and Canadian BQ-9000 producer members. The analysis from both the 2017 and 2018 reports show that the vast majority of biodiesel readily exceeded the performance specification limits in ASTM D6751, the standard for biodiesel.

“These reports show what we’ve been saying for years,” said Scott Fenwick, NBB technical director. “Biodiesel fuel is of the absolute highest quality, and these reports prove it. Having this data every year will go a long way in demonstrating to OEMs and regulatory agencies that biodiesel should be the fuel of choice for any diesel engine.”

As part of the data-gathering process (and under BQ-9000 requirements), biodiesel producers have their own B100 fuel analyzed against the full specifications at the point of production, then provide the NBAC with the resulting data. NBAC randomizes and anonymizes the results and provides the final version to NREL for statistical analysis.

BQ-9000 is a voluntary program for the accreditation of producers, marketers, laboratories and retailers of biodiesel fuel. It is a unique combination of ASTM D6751 and a quality systems program that includes storage, sampling, testing, blending, shipping, distribution, and fuel management practices. To receive accreditation, companies must pass a rigorous review and inspection of their quality management processes by an independent auditor while participating in annual audits and meeting the additional requirements under the program.
