CRANBURY, N.J. (DTN) -- The number of Renewable Identification Numbers generated in April edged higher for the D3, D4 and D6 nested categories while declining for the D5 and D7 subsets, according to the Environmental Protection Agency.
The D6 renewable fuel nested category is by far the largest subset under the Renewable Fuel Standard, which is overwhelmingly satisfied with conventional corn-based ethanol. In April, 10.2 million more RINs were generated than during March for total D6 RIN generation of 1.244 billion, the highest monthly total since January. The RIN total was generated on 1.235 billion gallons of qualified renewable fuel.
During the first four months of 2018, 4.889 billion D6 RINs were generated, a pace that would fall 333 million RINs shy of the 15-billion-gallon mandate.
Biomass-based diesel D4 RIN generation totaled 314.4 million in April, up 14.5 million from March, and at the highest monthly total since December. D4 RIN generation in April was generated on 203.8 million gallons of qualified biomass-based diesel, such as biodiesel and renewable diesel. Each gallon of biomass-based diesel generates 1.5 D4 RINs.
Cellulosic biofuel volume of 20.7 million gallons created an equal amount of D3 RINs in April, up 293,000 gallons.
Advanced biofuel submitted for D5 RIN generation declined by 1.5 million gallons to a three-month low at 5.1 million gallons in April. D5 RIN generation declined by 2.6 million on the month to 6.6 million.
Cellulosic diesel volume submitted for D7 RIN generation fell by 109,000 gallons to 487,000, generating 489,146 RINs in April.
