Renewable biofuels are being developed to offset the use of every type of fossil fuel. One advantage of Gevo’s sustainable aviation fuel, renewable diesel, and renewable gasoline biofuels is that they meet the standards established for their respective fossil fuels. This means they can drop right into the tank of the vehicle or aircraft for which they are made and have an immediate environmental impact on aviation, trucking, mass and personal transportation, and more, because they reduce the carbon intensity with every gallon of fossil fuel they replace.
Gevo is constantly researching and developing new ways to make biofuel, from inedible corn and from other feedstocks including lignocellulosic sources that are considered waste.
While there are five different pathways to creating renewable jet fuel, Gevo uses the Alcohol-to-Jet synthesized paraffinic kerosene or ATJ-SPK method to create the necessary 12-carbon chain from its isobutanol, a product created in the initial fermentation.
This gasoline replacement is already in use in Formula 1 racing in Europe, and for packaged fuels. Gevo uses its isobutanol as a base to create the 8-carbon chain found in the fuel cells of the fastest racecars.
Isobutanol is the starting point for other fuels that we produce and market, but it’s a product in its own right, born of our synthetic biology to create a yeast that manufacturers it in our proprietary fermentation methods. Isobutanol is a blendstock oxygenate for gasoline and works well in marine and small engines.
Gasoline blended from isooctane made from corn or other renewable feedstocks, and blended with isobuanol or other renewable oxygenate will have low carbon intensity and a reduced carbon footprint. Gevo already makes the components, and as costs fall, this may be the fuel of the future for personal transportation.
Diesel drives much of the freight hauling and transportation around the world, and to have a renewable replacement would reduce a large part of the world’s transportation carbon footprint and greenhouse gas emissions. At Gevo, we have developed a way to make biodiesel from isobutanol and fusel oils, natural waste byproducts of the fermentation process.
It’s the original fermented fuel blendstock, made from corn and lignocellulosic feedstock.
Renewable Natural Gas (RNG) is derived from cow manure. Because it provides renewable energy and reduces emissions related to dairy farms and agriculture by capturing the naturally formed methane that leaks off of manure left in the field, it made sense to add it to Gevo’s circular economy model. It was first conceived as a source for low-carbon-intensity thermal energy to power the fermentation process for alcohol-to-jet and other advanced-renewable-fuel pathways at production facilities currently under development, as well as other planned facilities. But the reduced carbon score is adds to its appeal so it’s found its own market. We currently inject RNG directly into pipelines to be sold into markets where Low Carbon Fuel Standards are in place to offer tax credits, such as California.
