Petrobras Cellulosic Ethanol Project - Who's on First?


By Robin J. Johnson, Ph.D.

In the ongoing quest by Petrobras to enter the cellulosic ethanol field, at least two companies appear to be involved. Novozymes of Denmark and KL Energy of South Dakota have both signed agreements to develop cellulosic ethanol technology for sugarcane bagasse.

The relationship between the three companies isn't clear. Petrobras' ethanol production activities are handled through its subsidiary, Petrobras Biocombustivel, which plans to hold a 45.7% equity interest in Acucar Guarani, the fourth largest sugarcane processor in Brazil, and a 49% equity stake in Nova Fronteira Bioenergia S.A., a joint venture with Grupo Sao Martinho.

Novozymes is a major supplier of enzymes for (among other things) biofuel production. The company is a leader in cellulosic ethanol enzyme technology.

KL Energy claims to have a proprietary process for producing cellulosic ethanol. Their technology includes thermal and mechanical pretreatment and enzymatic hydrolysis of cellulosic materials and fermentation of both C5 and C6 sugars.

Is Novozymes supplying enzymes for KL Energy's process to be integrated in a Petrobras sugar mill? Here's what we know.

In August of 2010, Petrobras, and KL Energy Corporation signed a joint development agreement for technology to turn sugarcane bagasse into ethanol. The 18-month project includes an investment by Petrobras of $11 million to adapt KL Energy’s demonstration facility in Upton, Wyoming to use bagasse. The agreement provides Petrobras with the option to license KL Energy's technology for use within Petrobras Group assets. Integration of KL Energy technology into one of Petrobras’ Brazilian sugarcane mills is scheduled to go online sometime in 2013.

On October 15, 2010 Novozymes and Petrobras announced an agreement to develop a process to make ethanol from sugarcane bagasse.

On October 21, 2010, KL Energy announced it had re-acquired all third party technology licensing agreements in order to facilitate commercialization of its technology with its strategic partners. On September 1, 2010 KL Energy signed a Master Coillaboration Agreement with add blue Consultoria Ltda. of Brazil. The two companies plan to set up a new company to handle business in Brazil.

KL Energy lists Petrobras as one of its partners on its website, but websites aren't always kept current. The Novozymes press release doesn't mention any other partners, though any cellulosic ethanol plant would have to use some form of pretreatment and fermentation technology. It will be interesting to see how all these arrangements shake out and are revealed over time.
