D7 - cellulosic diesel

D7 Renewable Identification Numbers (RINs), which cover cellulosic diesel, represent a niche and highly specialized category within the Renewable Fuel Standard (RFS) program. Historically, the volumes of D7 RINs have been limited due to the technological and economic challenges of producing cellulosic diesel at scale.

D7 RINs do not have distinct market prices. The main reason for this is that D7 RINs can be substituted with other types of RINs that meet the overall advanced biofuel requirements, such as D3 RINs, reducing the need for a separate market specifically for D7 RINs

In recent years, there have been gradual improvements in the production capacity for cellulosic diesel, but it still lags behind other renewable fuel categories. In 2023, the production of D7 RIN
