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.

Oxygen-containing gasoline additives called oxygenates, including ethanol, have provided an octane boost to the U.S. gasoline pool since 2000. This has allowed refineries to reduce the octane of refinery-produced gasoline, which increases their gasoline production capacity and efficiency while simultaneously helping achieve the goals for cleaner, lower-carbon fuels derived from domestic renewable feedstocks. A new approach to gasoline formulation promises to take this “sharing” of the octane load much further to exploit the unique octane-enhancing qualities of ethanol, although there are some real-world challenges to wider implementation. In today’s RBN blog, we explain what’s behind the concept of “hydrogen-rich” gasoline.
Some U.S. refiners report lower-than-market gasoline profit margins in the summer, which are often attributed to summer volatility specifications. But that is not always the primary issue; rather, some refiners have trouble generating enough octane-barrels due to the strong demand during the summer months, which can help drive price spikes. In today’s RBN blog we explain why, with a focus on octane, the primary yardstick of gasoline performance, quality and price, and show how refiners use a PIANO analysis to optimize their production.
In a refinery, crude oil is first distilled, which separates it into light, medium and heavy fractions. After that, refiners start performing chemical reactions to change the oil’s molecules from their natural form into those needed in modern fuels. But the catalysts used in that process aren’t only expensive, they essentially end up as hazardous waste at the end of their productive life. That helps to explain why there’s been a lot of interest in catalyst recycling, which advocates see as a way for refiners to improve both their profitability and their environmental performance. In today’s RBN blog, we continue our look into catalyst recycling — the technology, economics and trade-offs — and detail some of the pushback against it.
Refinery distillation units separate crude oil into light, medium and heavy fractions. After that, refiners start performing chemical reactions using catalysts — materials that accelerate chemical reactions — to change the oil’s natural molecules into the forms needed in modern fuels. In recent years, refiners have stepped up their efforts to recycle those catalysts to improve their profitability and environmental performance. In today’s RBN blog, we explain how catalysts, which were formerly disposed of as hazardous waste, are increasingly being recycled and reused in refineries.
The federal Renewable Identification Number (RIN) and California’s Low Carbon Fuel Standard (LCFS) have long served as tools to force renewable fuels like ethanol into the U.S. fuel supply. They are environmental credits that subsidize production of renewable fuels that would not otherwise be economically justified. Nuances embedded in the design of these credit systems have again kicked in to surprise the markets, this time with a hit to renewable diesel (RD) margins. Today’s RBN blog zeroes in on two root causes for that hit.
How can a business survive and thrive while spending $5.30 to make a product that sells for $1.90? That’s what’s happening in the booming renewable diesel (RD) market, where government subsidies allow RD to compete directly with petroleum diesel even though RD is inherently more costly to produce. But as new plants keep coming on stream, RD profit margins are coming under closer scrutiny. In today’s RBN blog, we analyze RD profit margins and show how they are changing as the market continues to expand.
The boom in renewable diesel (RD) production has triggered a race to secure the dozen different bio-feedstocks suitable for refining into diesel fuel. It’s an interesting story that impacts both the oil and agriculture industries, with twists and turns that will take years to play out. In today's RBN blog, we describe the current state of the market and highlight recent happenings in supply chains for two of those increasingly important bio-feedstocks — soybean oil and used cooking oil.
When the price of the Tier 3 sulfur credit hit a new high of $3,600 in October 2023, the tradable sulfur credit for gasoline moved from the background to center stage in refining circles. And while credit prices have retreated slightly to about $3,400, they still represent a nearly 10-fold increase over two years and translate to a Tier 3 compliance cost of almost $3/bbl, raising concerns from refiners in a highly competitive market. In today’s RBN blog, we look at how refiners are adapting and the investments that could reduce the cost of compliance.
The price of the Tier 3 gasoline sulfur credit hit $3,600 in October, up by a factor of 10 since 2022 and roughly in line with the all-time high reached in 2019. The high price of this important credit is a direct indicator of the true cost of compliance with the Environmental Protection Agency’s (EPA) Tier 3 gasoline sulfur standard and has raised some alarm recently in refining and financial circles. In today’s RBN blog, we give some specific examples of how refiners and investment analysts are reacting.
The price of the Tier 3 gasoline sulfur credit hit $3,600 in October, up by a factor of 10 from two years ago and roughly in line with the all-time highs seen in late 2019. This tradable credit allows refiners to sell gasoline that exceeds the sulfur specification on gasoline sold in the U.S. In today’s RBN blog, we examine what’s behind the credit’s steep and steady rise — and why it matters.
U.S. production of hydrogenated renewable diesel (RD), which is made from soybean oil, animal fats and used cooking oil, is growing faster than expected. That may sound like good news for the renewable fuels industry, but it comes with the fear that the rapid growth might push RD production levels well past the mandates set by the Renewable Fuel Standard (RFS), potentially triggering a sudden crash in Renewable Identification Number (RIN) prices that — if it happens — would rock the market. In today’s RBN blog, we estimate the likelihood and possible timing of such a market-shaking event.

The Renewable Identification Number (RIN) has long served as the tool used to force renewable fuels like ethanol and soybean oil into the U.S. gasoline and diesel supply. A creation of the Renewable Fuel Standard (RFS), RINs act as a subsidy that enables the production of renewable fuels that would not otherwise be economically justified. RIN prices are set by the usual workings of supply and demand, but chatter has bubbled up recently in the renewable fuels ecosystem that prices for a particular variety of RIN could be headed for a crash. In today’s RBN blog, we explain what’s behind the talk about RIN prices.
If you buy premium gasoline, you’ve probably noticed its price differential versus regular has been increasing in recent years. That is a sign of the rising value of octane, the primary yardstick of gasoline quality and price. In this blog series we’ve examined a new gasoline sulfur specification called Tier 3, which is causing complications for U.S. refiners looking to balance octane and gasoline production while still meeting the regulatory limits on sulfur. In today’s RBN blog, the fourth and final on this topic, we provide an analysis of the obscure Sulfur Credit Averaging, Banking and Trading (ABT) system, which allows refiners to buy credits to stay in compliance with the Tier 3 specs. The price of these credits quintupled in 2022, another sign of a tight octane market that will be attracting increased attention in the months and years ahead.
