cellulosic biofuels

Familiar corporate names like Cummins, Freightliner and Waste Management have joined forces with dozens of less-familiar public companies and startups to form what some might call a new U.S. industry. Thousands of commercial trucks powered by compressed natural gas (CNG) are on the roads nationwide, many of them filling up at dedicated fueling stations offering a compressed form of renewable natural gas (RNG), a cellulosic biofuel typically sourced from landfills and dairy farms. In today’s RBN blog, the third and final in our series on the D3 Renewable Identification Number (RIN), we show how this young industry could emerge as a commercial success for cellulosic biofuels, although political and regulatory risk remains. 

A primary objective of the Renewable Fuel Standard (RFS) implemented in 2007 was to stimulate the production of at least 16 billion gallons/year of gasoline and diesel made from cellulosic biomass, or non-food crops and waste biomass like corn stalks, corncobs, straw, wood, wood byproducts and animal manure. But the vision of making gasoline from wood chips never materialized and today’s cellulosic biofuel is a whole different ballgame. In today’s RBN blog, we look at the evolution of cellulosic biofuels and the D3 Renewable Identification Number, aka the D3 RIN. 

A primary objective of the federal Renewable Fuel Standard (RFS), when it was expanded back in 2007, was to stimulate by 2022 the production of at least 16 billion gallons/year of gasoline and diesel made from cellulosic biomass in conversion plants resembling small refineries. After getting lots of headlines in the early days of renewable fuels, that vision faded into the background and attention shifted to the use of ethanol in gasoline and the production of diesel from soybean oil, but cellulosic biofuels — non-food crops and waste biomass like animal manure, corn cobs, corn stalks, straw and wood chips — are back in the spotlight thanks to a regulatory quirk. In today’s RBN blog, the first in a series, we review the unusual history of the D3 Renewable Identification Number (RIN), the subsidy designed to stimulate cellulosic biofuel production, and the recent impact on heavy-duty trucking.
