NREL publishes findings of Assessment of BQ-9000 Biodiesel Properties for 2024

In Missouri, the National Renewable Energy Laboratory (NREL) announced the findings of the Assessment of BQ-9000 Biodiesel Properties for 2024, the eighth in a series of annual reports documenting the quality of biodiesel from U.S. and Canadian producers participating in the industry’s voluntary BQ-9000® accreditation program.

The report, developed in partnership with Clean Fuels Alliance America and authored by Robert L. McCormick of NREL, analyzes monthly quality data provided by BQ-9000 accredited producers throughout 2024. The study evaluates critical fuel quality parameters within the ASTM D6751 and Canadian CAN/CGSB-3.524 specifications. These include test methods such as kinematic viscosity, sulfated ash, distillation temperature, carbon residue, cetane number, and levels of key metals including sodium, potassium, calcium and magnesium.

Results from the 2024 assessment reaffirm that biodiesel produced under BQ-9000 accreditation consistently exceeds the performance limits set by ASTM International’s D6751 specification — the industry’s global consensus standard for biodiesel quality.
