Highwater CEO: Biobutanol is 'next step in biofuels'

By Kris Bevill | December 06, 2011

Lamberton, Minn.,-based Highwater Ethanol LLC has signed a letter of intent with Butamax Advanced Biofuels LLC to potentially retrofit its 50 MMgy corn ethanol plant to produce biobutanol. The agreement makes Highwater the first entrant to the Butamax Early Adopters Group.

“Butamax offers our shareholders both new technology, extensive engineering resources needed to retrofit our existing facility, and a commitment to the long-term success of the biofuels industry,” Highwater CEO Brian Kletscher said. “We are very excited about the letter of intent with Butamax and look forward to working with them in the advancement of biobutanol as the next-generation biofuel.”

Discussions between Highwater and Butamax regarding the retrofit plans are expected to last through the coming year. Kletscher said that he is hopeful an agreement will be reached by the end of 2012 and that retrofit activities will begin in 2013. Highwater will continue to produce ethanol until the retrofits are complete. The company’s decision to explore biobutanol production was driven by a desire to be a leader in renewable fuels production, he said. “Butanol has a potential to be a drop-in fuel that can be utilized throughout the nation,” he said. “It’s the next step in biofuels.”

Butamax, a joint venture between BP and DuPont, was formed in 2009 to commercialize the production of biobutanol. The company currently operates a demonstration-scale facility in Hull, England, as well as a technology laboratory in Paulinia, Brazil, which is focused on developing the sugarcane-to-biobutanol process. Its Early Adopters Group is expected to be comprised of the current ethanol operators willing to install Butamax’s proprietary biobutanol technology. Matrai, chief operating officer at Butamax, said relationships are currently being developed with a group of ethanol producers, including Highwater. “These facilities are among the most efficient, well-managed facilities in the United States,” he said, adding that his company is pleased to have begun talks with Highwater. “Highwater’s operational performance is among the best in the industry, making them an excellent biobutanol production partner.”

According to Butamax, when blended at 16 percent volume, biobutanol delivers twice the energy content of 10 percent ethanol blends. The fuel is also compatible with current automobile engines and fuel infrastructure. Butamax said the favorable blending properties of biobutanol could reduce refiners’ cost of gasoline production and could also be used to comply with renewable fuel standard requirements.

    I have a question for Butamax: How do the antiknock characteristics of 16% biobutanol-gasoline blends, compare with various E10's available at service stations throughout the USA? We should also consider various biobutanol-ethanol-gasoline blends, to see how they work out regarding vapor pressure, antiknock characteristics, and energy content.

    100% butanol has an octane rating of 87. Adding ethanol will increase the octane rating and eliminate chance of engine knocking. I am not sure what the octane rating is for 16% butanol/84% gasoline however the calculation should not be too difficult.

    Fungible grade gasoline is blended below octane spec so when ethanol is blended in at 10% it will meet 87 octane spec or higher. Fungible gasoline to be blended with bio butanol will need to be a higher octane. Refiners may not like this because octane is money so it will be more expensive to blend for bio butanol. That being said butanol has a higher btu content than ethanol so should get better mileage has lower RVP which is a plus for summer blend spec RVP is the number one off spec offender in summer. Plus butanol is less aggressive on rubber hoses, and has a lower affinity for water which may allow for blending at the refinery and pipeline transport (that is a huge savings in dollars). iso-butanol has a higher octane rating than n-butanol. So if Butamax can isomerize that is even a better deal.
