Corn Butanol: Gevo’s Technology, Economics, and Performance

The document examines Gevo's GIFT platform, which converts corn sugars into isobutanol for use as a fuel additive or chemical feedstock. It highlights that achieving 'advanced biofuel' certification from the US EPA is critical for the technology's commercial success, as the product would otherwise be only marginally better than ethanol in terms of carbon impact. The report notes significant financial instability at Gevo, including a risk of insolvency and potential delisting from the NASDAQ. Economically, retrofitting an ethanol refinery with GIFT and a combined heat and power (CHP) system would increase capital requirements by approximately 60%. Additional risks include past process contamination at a Minnesota plant, ongoing patent litigation with Butamax, and the emergence of potentially cheaper ethanol-to-butanol conversion technologies.

• Gevo's GIFT platform is designed to be compatible with the existing global ethanol production capacity of approximately 23 billion gallons per year, allowing existing refineries to be adapted for isobutanol production.
• To meet the RFS2 threshold for advanced biofuel certification, Gevo's process requires a renewable gas and electricity component, such as an anaerobic digester/generator; without this, the product is only marginally better than ethanol.
