Gevo Makes Renewable Low-Carbon Biofuels That Help Boats Run Better

Gevo, Inc., is a U.S. based biofuel company that produces renewable fuel to help boats run better while reducing their carbon footprint.

Low Carbon Cycle

All boaters who use gasoline engines can benefit from isobutanol, an oxygenate blendstock that mixes with gasoline, and improves performance and reliability. Boaters understand the impact of greenhouse gases better than most people because they see the effects fossil-fuel emissions have on the environment, as the increased acidity harms fragile marine ecosystems.

Gevo uses its vast knowledge of synthetic biology and industrial chemistry techniques to determine new ways to produce low-carbon, renewable biofuel and chemicals. Creating proprietary processes, the company builds the molecular structure of fuels or chemicals, then figures out how to scale it up to create marketable alternatives to fossil fuels or petro-based chemicals.

The marine industry is an important market for Gevo’s isobutanol, and the technical properties of isobutanol shine in this application,” said Dr. Patrick Gruber, Gevo’s Chief Executive Officer.We are delighted with the results of the testing and to have the endorsement of the NMMA (US National Marine Manufacturers Association). Isobutanol has proven to be an effective, highly compatible biofuel for the recreational boating industry.

In Details

Gevo makes isobutanol from inedible No. 2 corn, which is considered an excellent gasoline oxygenate blendstock. Isobutanol, sometimes called “biobutanol”, has numerous advantages:

  • · Isobutanol does not absorb water – a key feature for the open-vented fuel systems most boats use. Isobutanol also stays mixed with gasoline, rather than phase separating with any water in the system.
  • · It has a chemical makeup that is not corrosive on marine fuel lines and fuel-system components.
  • · It will not damage fiberglass fuel tanks, nor will it cause galvanic corrosion in aluminum fuel tanks.
  • · U.S. based National Marine Manufacturers Association (NMMA) has endorsed isobutanol as a fuel oxygenate blendstock.
  • · Gevo takes carbon out of every step of its production process, so the carbon footprint is substantially lower than even other biofuels.
A Process to Make Low-Carbon, Renewable Diesel
Marine Industry Testing

Gevo has also recently developed a process to make low-carbon, renewable diesel. When this fuel is introduced, it will help meet increased demand as additional regulation requirements go into effect.

The renewable diesel is expected to reduce particulates and CO2 emissions, and will help the marine sector reduce sulfur emissions to meet new international water regulations beginning in 2020. The proprietary, breakthrough process will convert low-carbon isobutanol or low-value “fusel oils”—a mixture of alcohols that are byproducts from fermentation processes—into renewable diesel fuel.
