Advanced D5 RINs continue to climb, D3, D6 RINs down slightly

U.S. EPA data on RINs generation through September shows D3 cellulosic biofuels RINs generation tapered off slightly for the month of September, after a steady climb seen each month throughout the year. D6 renewable fuel RINs (primarily corn ethanol) were down slightly from the previous month, while advanced biofuel D5 RINs continue to climb. Biofuel producers assign renewable identification numbers (RINS) to each gallon-equivalent of fuel produced, which are then used by obligated parties to show the EPA that they have complied with the blending requirements under the renewable fuel standard.

Cellulosic, D3, RINS were down in September at 12.3 million, 1.5 million lower than August’s and the lowest since June’s 12.5 million D3 RINs generation. D3 RINs generation for 2015 through September, adjusted for corrections, totaled 87.95 million; of that 14.2 million were generated by importers. Broken down by type of fuel, D3 RINs generation for the first nine months included 1.65 million from cellulosic ethanol, 50.8 million from renewable CNG and 36.3 from renewable LNG.

Advanced biofuel, D5, for September continued to climb, reaching 24.6 million, up from August’s 20.8 million, as shown in the Oct. 15 data on the EPA website. D5 RINs generation for the year through September totaled 90.4 million. Just over half, 45.9 million D5 RINs were generated by importers. By type of fuel, 64.6 million advanced biofuel D5 RINs were ethanol, 18.6 million naptha, 505,000 heating oil, 6.8 million non-ester renewable diesel and 5,000 CNG.

Biomass-based diesel, D4, RINs totaled 161.4 million in September, down from July’s peak for the year so far of 192.8 million and August’s 185.7 million. D4 RINs for the year through September total 2.05 billion; 232.3 million were generated by importers and 180.1 million foreign generation. Biodiesel accounted for 1.65 billion D4 RINs, non-ester renewable diesel accounted for 406.6 million,

Cellulosic diesel, D7, RINs generation was zero in September, as it has been for all but two months in 2015.

D6 RINs, the renewable fuel dominated by corn ethanol, totaled 1.22 billion in September, down from August’s 1.26 billion. The corrected total for the first nine months was 11.02 billion. Of that, 346.5 million were foreign generation or generated by importers. Ethanol comprised the lion’s share, when broken down for the year to date by fuel type, at 10.68 billion D6 RINs. Biodiesel accounted for 89.2 million and non-ester renewable diesel 253.7 million.

EPA reports the total available D3 cellulosic RINs as 2.9 million assigned and unlocked, 15.7 million separated and locked and 69.2 million separated and unlocked, with 773,000 D3 RINs retired. D5 advanced biofuel RINs include 19.2 million assigned and unlocked, 227,000 separated and locked and 70.1 million separated and unlocked; 24,660 RINs are retired. For D6 RINs, 372 million RINS have been retired; 8 million are assigned and locked, 688 million assigned and unlocked; 439.6 million are separated and locked, while 9.5 billion have been separated and unlocked. The total RINS assigned and separated for all D-codes are 509.6 million retired, 522.7 million locked and 12.2 billion unlocked.
