Isooctane Is a Renewable Gasoline Replacement

How can a gallon of gas be completely decarbonized? Make it with renewable isooctane, naphtha, and alcohol from the Gevo product portfolio. When gasoline is made from corn or other renewable feedstocks, it has no fossil carbon.

Our isooctane is already being used by professional auto racing teams.

As our isooctane penetrates the market even more, it will become more and more cost effective to be used as a base for renewable gasoline.

 

Gevo Puts the “New” in Renewable Fuel with Isooctane and Isobutanol Powering a Cleaner Future Now

By Dr. Pat Gruber, CEO, Gevo, Inc.

You may have heard recently that Gevo reached an agreement to provide renewable gasoline to the fleet vehicles for the City of Seattle. It’s a four-year deal, with the potential for three extensions of two years each to supply 600,000 gallons per year of renewable isooctane and 200,000 gallons per year of renewable isobutanol. This contract is a big deal because Seattle is taking on the problem of greenhouse gas (GHG) fleet emissions through its Green Fleet Action Plan.

The city and its Green Fleet Program Manager, Philip Saunders, identified a problem: Transportation is the cause of more than 60 percent of GHG emissions in the Puget Sound area. They set some aggressive goals to help solve it, including a five-year horizon to reduce GHG emissions by 50 percent by 2025, and to use only fossil-fuel-free fuel by 2030.

The city is taking a bold step to break away from fossil-based fuels and to reduce CO2 and particulate emissions. Gevo will supply isobutanol to begin, and then migrate into our renewable gasoline through the use of isooctane.

Gevo’s renewable gasoline flies in the face of the unfounded myth that says using biofuels means a compromise on performance. In fact, our isooctane is a premium product that is helping us gain ground on our goal to position it to replace the whole gallon of gasoline. Our isooctane is an ethanol-free, high-octane gasoline that’s chief market has been high-performance fuel for racing and classic cars.

Our renewable isobutanol is a premium oxygenate blendstock that reduces GHG emissions in reformulated gasoline (RFG) zones that have been mandated since the 1990 Clean Air Act to reduce smog in urban areas throughout the country. While the majority of the bio-based oxygenate in use has been ethanol, Gevo’s isobutanol offers several benefits: it doesn’t absorb water and phase separate in open fuel systems, and also can add octane for improved engine performance.

A large part of the Seattle Green Fleet Action Plan is rapid electrification of the city fleet, which makes sense for reducing transportation GHG emissions. But this plan will requires a sizable upfront investment to replace vehicles, as well as building out a charging infrastructure.

Isooctane makes sense for Seattle during this transition, since city fleet vehicles need to run well over the long term of this transition, and aging vehicles may see delays in their replacement schedule. Our performance fuels meet the same standards as the fossil fuels for which they were originally written. Also, our fuels are fungible, so if a fleet vehicle runs low on gas and needs to buy fuel to get back to the city garage, they can top up with any gasoline. It’s no wonder we consider clean cities to be an area of potential growth for our products, as urban governments use all sorts of vehicles to conduct municipal business.

From race cars to city vehicles, Gevo’s renewable gasoline, isooctane, and isobutanol can power transportation into the future, helping reduce GHG emissions and shrinking the carbon footprint of every vehicle that uses them.
