Gevo Selects Polynaphtha™ Technology and Engineering from Axens

MARCH 8 - 2021
Gevo Selects Polynaphtha™ Technology

Gevo Selects Polynaphtha Technology and Engineering from Axens for its Net-Zero 1 Project in South Dakota for Renewable Gasoline and Sustainable Aviation Fuel 

Axens today announces that Gevo, Inc. selected its PolynaphthaTM oligomerization technology for its Net-Zero 1 project in Preston, South Dakota. Axens scope will include technology license, basic engineering, and catalyst supply for the conversion of renewable olefins into a flexible slate of renewable gasoline and jet fuel.

As we look to build our Net-Zero 1 project in South Dakota, we chose to work with Axens because of their commercial engineering, project execution, and plant support track record, based on 24 heterogeneous oligomerization references. Axens has done a great job of adapting its technology to meet our special needs to produce drop-in jet fuel and gasoline hydrocarbons from isobutanol, a process-chain we’ve been successfully running at South Hampton Resources for the past 10 years.  We expect that the experience of Axens should help to ensure the successful deployment, start-up, and operation of the hydrocarbon part of our Net-Zero 1 plant,” said Chris Ryan, President, Chief Operating Officer and Chief Technology Officer of Gevo.

This project represents yet another example of Axens applying its flexible technologies to the developing low-carbon fuels market. We congratulate the Gevo team on this significant milestone and are pleased to renew Axens commitment throughout the final stages of project execution, start-up, and operation.” – Romain Lemoine, VP of Process Licensing, Axens Americas.


About PolynaphthaTM technology

Axens PolynaphthaTM oligomerization technology provides a robust solution to convert a range of olefins into a flexible slate of drop-in, high-quality renewable fuels, including gasoline, jet fuel, and diesel, consistent with Axens commitment to help reduce the carbon intensity of the transportation fuel pool. 

The technology is backed by more than thirty years of commercial heterogeneous catalyst oligomerization experience in both the refining and renewable markets.


About Gevo

Gevo’s mission is to transform renewable energy and carbon into energy-dense liquid hydrocarbons. These liquid hydrocarbons can be used for drop-in transportation fuels such as gasoline, jet fuel, and diesel fuel, that when burned have potential to yield net-zero greenhouse gas emissions when measured across the full lifecycle of the products. Gevo uses low-carbon renewable resource-based carbohydrates as raw materials, and is in an advanced state of developing renewable electricity and renewable natural gas for use in production processes, resulting in low-carbon fuels with substantially reduced carbon intensity (the level of greenhouse gas emissions compared to standard petroleum fossil-based fuels across their lifecycle). Gevo’s products perform as well or better than traditional fossil-based fuels in infrastructure and engines, but with substantially reduced greenhouse gas emissions. In addition to addressing the problems of fuels, Gevo’s technology also enables certain plastics, such as polyester, to be made with more sustainable ingredients. Gevo’s ability to penetrate the growing low-carbon fuels market depends on the price of oil and the value of abating carbon emissions that would otherwise increase greenhouse gas emissions. Gevo believes that its proven, patented, technology enabling the use of a variety of low-carbon sustainable feedstocks to produce price-competitive low carbon products. These products, such as gasoline components, jet fuel, and diesel fuel yields the potential to generate project and corporate returns that justify the build-out of a multi-billion-dollar business.

Gevo believes that Argonne National Laboratory GREET model is the best available standard of scientific based measurement for life cycle inventory or LCI. Learn more at Gevo’s website:
