Decarbonizing the Process

Many people want to know: Why are biofuels referred to as carbon neutral?

The answer is that biofuels use carbon that is already in the carbon cycle that occurs naturally in our world’s balanced environment. So while biofuels release less carbon into the atmosphere, the key is that they don’t introduce “fossil carbon” or carbon that has long been sequestered within the earth in the form of oil, natural gas, and coal deposits.

But not all biofuels are created equal in their low carbon claims. Everything Gevo does is dedicated to reduce the carbon intensity of every gallon of its biofuel.

We have focused on decarbonizing the entire process of creating our biofuel. The goal is to reduce the biofuel carbon footprint at every step of the process to get to carbon neutral biofuel and in some cases carbon-negative biofuel.

To do that:

  • Gevo works with the farmers who grow the corn to reduce the carbon released through no-till and low-till farming techniques. This carbon-farming solution captures carbon and sequesters it in the soil.
  • Gevo plans to install manure digesters on farms to capture methane that can be turned into renewable natural gas.
  • Gevo has taken an existing ethanol plant and converted it to an isobutanol plant, rather than requiring green-field construction that is expensive and carbon intensive.
  • Gevo will use wind turbines to power its isobutanol plant, to eliminate the need for electricity generated on the grid using fossil fuels.
  • Gevo makes fuels that can use the existing infrastructure, including pipelines. This carbon-neutral transport minimizes the carbon intensity of building new infrastructure to handle less fungible fuel types.

The world doesn’t stop because of the dangers of climate change—we’ve all seen that. Airline carbon emissions don’t keep them from flying. Carbon-neutral and carbon-negative biofuels allow the world to continue to conduct business and move people and freight, keeping economies vital and strong, and supplying populations with the food and goods they need to continue to improve their quality of life. And every gallon of renewable biofuel could replace a gallon of fossil fuel. And that’s how biofuels can reduce carbon emissions.
