Gevo has been producing and selling its patented alcohol-to-jet fuel (ATJ) derived from isobutanol since 2011. Gevo is working toward further commercializing its patented ATJ, which is a clean burning, homegrown, drop-in jet fuel that has the potential to deliver aviation biofuels at scale and at competitive cost. Fossil-based jet fuel is one of the largest expenses for airlines. Gevo’s ATJ is expected to help reduce the airline industry’s carbon footprint and help control fuel costs.

Before Gevo’s ATJ could be sold to airlines, it had to pass a series of technical and safety tests. After six years of rigorous performance assessments conducted by ASTM International, including extensive engine testing and data analysis by all of the major original equipment manufacturers, the ASTM D7566 specification was revised to include Gevo’s ATJ in April of 2016. The revision includes ATJ derived from renewable isobutanol, regardless of the carbohydrate feedstock (i.e. cellulosics, corn, sugar cane, molasses, etc.). For more on Alaska Airlines flying with Gevo’s cellulosic renewable ATJ click here for a PDF download.

Gevo’s ATJ can now be seamlessly integrated into the existing distribution infrastructure and onto commercial aircraft where a domestic, competitively priced, sustainable supply of biofuels is expected to meet the growing demand for fuel alternatives in one of the world’s largest industries for fuel consumption.

Gevo is a leading renewable chemicals and advanced biofuels company. We have developed bio-based alternatives to petroleum-based products using a combination of synthetic biology and chemistry. We produce isobutanol, a versatile platform chemical for the liquid fuels and petrochemicals markets. Isobutanol has broad market applications as a solvent and a gasoline blendstock that can help refiners meet their renewable fuel and clean air obligations. It can also be further processed using well-known chemical processes into jet fuel and feedstocks for the production of synthetic rubber, plastics and polyesters.


Gevo’s Alcohol to Jet Fuel clears key ASTM hurdle 

March 28, 2016S

First commercial test flight with Alaska Airlines comes closer

In Colorado, ASTM International Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and Subcommittee D02.J on Aviation Fuel passed a concurrent ballot this week approving the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) to include alcohol to jet synthetic paraffinic kerosene derived from renewable isobutanol.

The Gevo commercial test with Alaska

Alaska Airlines is now poised to fly the first-ever commercial test flight using Gevo’s renewable alcohol to jet fuel (ATJ).  Gevo is preparing the shipment of ATJ to Alaska Airlines for this first flight. Alaska Airlines will work with the Federal Aviation Administration to schedule the flight using Gevo’s ATJ.

The ASTM technical review

The D02.J Ballot passed two levels of ASTM technical scrutiny: subcommittee and main committee ballot and is in the final stages of Society Review. The ASTM process is substantially complete as it relates to the approval of the D02.J Ballot.  In order to fully complete the process, the ASTM still needs to close the Society Review, perform a final ballot tally, and publish the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) on its website.  It is expected that these final actions will be completed by the ASTM in early April.

Once the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) is published by the ASTM, Gevo’s ATJ will be eligible to be used as a blending component in standard Jet A-1 for commercial airline use in the United States and in many other countries around the globe.  Gevo’s ATJ would be eligible to be used for up to a 30% blend in conventional jet fuel for commercial flights.

Why a big deal?

In September, we learned Gevo aimed to increase isobutanol production at Luverne to a range of 750,000 to 1 million gallons in 2016, up 7-10x from expected 2015 production levels, in part to increase sales of isobutanol into core markets such as the alcohol-to-jet (ATJ), marina, off-road, isooctane and solvents markets.

Underpining this? Approximately $5.0M of capital expenditures for a distillation system to purify isobutanol on-site, an addition to our seed train to allow Gevo to produce its yeast on-site and a stainless steel fermenter to replace one of the existing carbon steel fermenters that has reached the end of its useful life.

The goal? Reducing the variable cost of producing isobutanol at Luverne to a range of $3.00-$3.50/gallon*, a decrease of approximately 50% from the current cost of production, enabling isobutanol to be produced at a positive contribution margin, based on an expected average selling price for isobutanol of between $3.50-$4.50/gallon

Gevo yields at this time

Gevo has demonstrated yields of 1.80-1.85 gallons per bushel and batch sizes of 16-18 thousand gallons per batch at Luverne, it said in September.

The commercial prospects?

With jet fuel selling at $0.97 per gallon based on $40 oil, don’t expect big orders from Alaska just yet. But they’ve seen as everyone has the projections of $70 oil by year end. While on a pro-rated basis we would not expect to see Alaska doing much more than demonstration that “it is doing something” based on these prices — clearly airlines need to show that they are doing something, else they’ll be regulated country-by-country on CO2 emissions.

What’s the carbon penalty right now based on Gevo’s cost structure? With $3.00 isobutanol, and that’s at the lowest possible end, that corresponds to the jet fuel cost when there’s (roughly) $100 oil. But on the other hand, there’s the $0.70 advanced bioful RIN, and there’s 1.5-1.7 in a gallon of jet fuel, so consider that there’s a $1.05 to $1.19 in RIN support there. That could well support a business for Gevo even with $70-$80 oil.

Reaction from the stakeholders

“We’re pleased that this newly-revised standard now supports isobutanol based alcohol-to-jet aviation biofuels and we look forward to flying it this year. Developing a domestic, competitively priced, sustainable supply of biofuels is fundamental to Alaska Airline’s long term sustainability goals,” said Joe Sprague, Alaska Airline’s Senior Vice President of External Relations.

Dr. Patrick Gruber, Gevo’s Chief Executive Officer, commented, “This ASTM revision is a major achievement and supports one of Gevo’s key products.  We believe that Gevo’s renewable ATJ provides a clear and cost-competitive path for commercial airlines to reduce their greenhouse gas footprints and reduce their particulate emissions from combustion. For Gevo, this step is expected to open a large and significant market to Gevo around which Gevo expects to build a profitable business.”

And Gevo is raising capital on the back of this

Gevo hailed the ballot as paving the way towards a commercial test of ATJ fuel. And, the company announced on the heels of this approval a complex financing plan.

Here’s the Gevo alphabet soup.

It will sell Series C units, with each Series C unit consisting of one share of common stock, Series F warrants to purchase a certain number of shares of common stock and Series H warrants to purchase a certain number of shares of common stock.

Not too bad so far. But, Gevo is also offering Series D units, in lieu of Series C units, to those purchasers whose purchase of additional Series C units in the offering would result in the purchaser beneficially owning more than 4.99% of the Company’s outstanding common stock following the completion of the offering.

The Series D units will consist of pre-funded Series G warrants to purchase one share of common stock, Series F warrants to purchase a certain number of shares of common stock and Series H warrants to purchase a certain number of shares of common stock.


Leveraging the same hydrocarbons technology that Gevo uses to convert isobutanol to jet fuel, Gevo also produces isooctane, or renewable gasoline. Whereas isobutanol can be used as a blendstock for a finished gasoline (with Gevo targeting isobutanol blends of 12.5% to 16%), the balance of such finished fuels is typically comprised of petroleum-based products. Gevo is looking to replace such petroleum-based products with its renewable isooctane. This would enable extremely high renewable content in gasoline, approaching almost 100% of the gasoline, while not sacrificing the performance of such fuels.

The market interest in renewable carbon-based fuels is increasing. Certain markets in Europe already place significant value on low carbon fuels, and other markets are moving in this direction, including parts of the U.S., such as California. Gevo believes its isooctane has the ability to address such demand successfully both from a performance, as well as a production cost standpoint. Given Gevo’s isooctane is virtually identical (chemically) to petro-isooctane, this should cause minimal adoption hurdles for the fuel.

Isobutanol: A Gateway to Chemicals and Fuels

Gevo’s commercialization efforts are focused on isobutanol, a naturally occurring four carbon alcohol. Isobutanol is an important platform chemical with broad applications in many chemicals and fuels markets. It is a “drop-in” product that should allow customers to replace petroleum-derived raw materials with isobutanol-derived raw materials without modification to their equipment or production processes. Because isobutanol can drop into existing infrastructure, it should provide for easy integration into existing chemical and specialty fuel production processes.

Gevo’s isobutanol has successfully cleared registration with the U.S. EPA as a fuel additive. It is the first isobutanol to be listed in the EPA’s Fuel Registration Directory and is now approved for blending with gasoline.

Isobutanol advantages. Gevo’s isobutanol-based products are chemically equivalent to those produced from petroleum-based raw materials, except they are produced via fermentation from renewable sources.

Our markets include:

  • Solvents and Coatings. A solvent-grade renewable isobutanol can be used in the existing butanol market as a cost-effective alternative to petroleum-derived solvents with a lower carbon footprint.
    Materials, Plastics, and Fibers. Isobutanol can be dehydrated to produce butenes, which are building blocks for the production of materials such as lubricants, synthetic rubber, PMMA, propylene, xylene, and PET. Gevo’s isobutanol can provide chemical companies with an alternative to petroleum-based butenes with potential advantages in cost, predictability and life cycle profile.
    Biojet Blendstock. Isobutanol has been converted to kerosene, which is a drop-in blend component for petroleum jet fuel. Bio-based kerosene has the potential to provide a cleaner burning, renewable jet fuel with a lower carbon footprint. Working with the Department of Defense, we have validated that alcohol-to-jet fuel is a clean-burning, homegrown, drop-in option.
    Specialty Fuels. For specialized uses, such as small-engine and/or marine fleet engines, it is important to have a fuel that does not cause shortened engine life or create operational safety issues, and can meet EPA emission targets. Isobutanol has a lower Reid vapor pressure value than ethanol and, with 30 percent more energy, generates significantly more renewable fuels (RIN) credits. It has a lower propensity for phase separation in the presence of water and has no stress corrosion cracking compatibility or elastomer incompatibility issues.
