What We Do

We transform renewable energy into low-carbon, drop-in fuels with a pathway to "net zero"(1)

Capturing Renewable Energy…

• • We design our business with carbon value in mind from the beginning

Photosynthesis

…Transforming it into Energy Dense, Liquid Hydrocarbons

• • Carbon value impacts everything we do

• • We are set up to maximize the value of renewable energy sources

• • We transform renewable energy sources into a "drop in" fungible commodity that can be easily stored and transported globally

H20

C02

Renewable Natural Gas (RNG)

Biogas captured from wastewater / stillage, livestock manure

Renewable Electricity

Cogeneration / Combined Heat & Power (CHP), Wind Power

 "Drop in" as a fuel to existing infrastructure and fleets(2)

 Infrastructure already exists allowing renewable energy to reach wide markets  Immediate and Scalable for significant carbon reduction. Consumers don't have to make any alterations to current vehicles

 Net Zero GHG footprint potential when burned to generate energy for transportation

• (1) "Net-zero" refers to the greenhouse gas or carbon balance across the complete lifecycle of a product. Gevo uses the Argonne National Laboratory's GREET model, the pre-eminent science-based lifecycle analysis model to measure and predict GHG emissions across the life-cycle of its products. The GREET model takes into account emissions and impacts "cradle to cradle" for renewable resource-based fuels including: inputs and generation of raw materials, agriculture practices, chemicals used in production processes of both feedstocks and products, energy sources used in production and transportation, and end fate of products, which for fuel products is usually burning to release energy.

• (2) Certain regulatory approvals required in some jurisdictions.
