What does GreenFuel do?

GreenFuel uses a portfolio of technologies to profitably recycle CO2 from smokestack, fermentation, and geothermal gases via naturally occurring species of algae. Algae can be converted to transportation fuels and feed ingredients or recycled back to a combustion source as biomass for power generation.

Codexis evolves enzymes for use in improving chemical manufacturing processes. Enzymes exist throughout nature and some have been used as biocatalysts to enable new, more efficient manufacturing processes, ranging from the manufacture of antibiotics to the production of monomers for use in plastics. Compared with chemical processing methods, enzyme-based methods are often faster, cleaner, and more efficient. Enzymes are highly selective catalysts, creating products of exceptional purity. The difficulty is that it is not always possible to find enzymes in nature that are suited to catalyzing a specific chemical reaction. That’s where Codexis’ proprietary technology comes in.

Green Chemistry

Over the last few years a lot of attention has been paid to Green Chemistry and its potential for helping to protect the environment and support sustainable industrial processes. More recently, it has become evident that in addition to improving the environmental footprint of products and processes, green chemistry can help chemical and pharmaceutical manufacturers improve the efficiency and reduce the cost of production. In other words, green chemistry is not only good for the environment, it’s good for business.

Gevo – Next Generation Biofuels

Gevo’s  team of biofuel experts is developing the next generation of biofuels that will provide a sustainable path to the replacement of petrochemicals like gasoline, diesel and jet fuel.

Advanced biofuels, which include butanol, isobutanol and other alcohol systems will:

  • Deliver the performance of gasoline without the environmental impact
  • Help to eliminate supply scarcity and reduce our dependency on foreign oil
  • Reduce greenhouse gases and dirty emissions

Making Renewable Fuels An Affordable Reality


Advanced biofuels like isobutanol and butanol can also address many challenges that first-generation biofuels such as ethanol have faced on their path to market: energy efficiency, transport and the need to modify existing engines. In contrast, butanol:

  • Has a higher energy content per gallon than many first generation biofuels
  • Does not absorb water and can be transported through the existing oil and gas distribution infrastructure.
  • Can be used in gas-powered vehicles without modification or blending, which eliminates our dependency on fossil fuels.

Partners and Investors

Virgin Green Fund

“Through Virgin Fuels, we look for investments in companies–such as Gevo–that will help to significantly reduce net greenhouse gas emissions, improve management of scarce resources, and have a long-term positive impact on our society.” – Virgin founder, Richard Branson

Founded by Sir Richard Branson, Virgin Green Fund was established to invest up to $400 million in U.S. and European companies in the renewable energy and resource efficiency sectors whose goals are to:

  • Reduce net greenhouse gas emissions and/or improving management of scarce resources,
  • Operate in environmentally and economically sustainable markets, and
  • Have a long-term positive impact on their communities and society more broadly

Khosla Ventures

“I think Gevo’s got fantastic scientific founders, great technology and a lot of very strong intellectual property. I think with our support and the support of Richard Branson of Virgin, it’ll be pretty exciting.” – Samir Kaul, General Partner at Khosla Ventures

Vinod Khosla, who was recently named the #1 Venture Capitalist by Forbes and Fortune, founded Khosla Ventures to offer venture assistance, strategic advice and capital to entrepreneurs. The firm helps entrepreneurs extend the potential of their ideas in both traditional venture areas like the Internet, computing, mobile, and silicon technology arenas, but also supports breakthrough scientific work in clean technology areas such as bio-refineries for energy and bioplastics, solar, battery and other environmentally friendly technologies.
