After a monumental year for biodiesel at ASTM, this session gives a broad-brush update on where specifications stand across every market. B20 is well-established, and higher blends are now backed by real data and real momentum. We'll cover this year's research on metals and phosphorus across all blend levels, plus the long-term B50/B100 storage results that helped pass B21-B50 in home heating oil. Looking ahead, streamlining efforts and the B5 allowance in the gas turbine spec head to ballot, and OEMs are now putting forward their own requests for B30 and B100 approval. Come learn why spec by spec, biodiesel is becoming a fixture of the fuel supply.
