Bio-isobutanol company Gevo signs licensing and joint development agreements with Porta in Argentina; corn feedstock
February 03, 2016
Gevo, Inc. has entered into a license agreement and a joint development agreement with Porta Hnos S.A. to construct multiple isobutanol plants in Argentina using corn as a feedstock.
The first plant is to be wholly owned by Porta and is anticipated to begin producing isobutanol in 2017. The plant is expected to have a production capacity of up to five million gallons of isobutanol per year. Based on projected isobutanol pricing, Gevo estimates that it could generate approximately $1 million in annual revenues once the plant is operational, through royalties, sales and marketing fees, and other revenue streams such as yeast sales.
Researchers improve efficiency of ethanol-to-butanol conversion with new bifunctional catalyst
December 04, 2015
Researchers at the University of Rochester and the University of Ottawa (Canada) have developed a highly selective (>99%) tandem catalytic system—a bifunctional iridium catalyst coupled with bulky nickel or copper hydroxides—for the conversion of ethanol (up to 37%) to n-butanol, through the Guerbet process.
The team was able to increase the amount of ethanol converted to butanol by almost 25% over currently used methods without producing unwanted byproducts. A paper describing the new system is published in the Journal of the American Chemical Society.
Bio-isobutanol company Gevo enters major licensing and development agreement with Praj
November 10, 2015
Gevo, Inc. has entered into a license agreement and a joint development agreement with Praj Industries Limited to enable the licensing of Gevo’s isobutanol technology to processors of non-corn based sugars, including the majority of Praj’s global customer base of ethanol plant owners. The two companies had signed a memorandum of understanding on licensing earlier this year. (Earlier post.)
As part of these agreements, Praj will invest substantial resources in the development and optimization of Gevo’s isobutanol technology for use with non-corn feedstocks including sugar cane, sugar beets, cassava, rice, sorghum, wheat and certain cellulosic sugars. This development work is anticipated to lead to process design packages (PDP) that would be expected to accelerate the licensing of Gevo technology to processors of these, particularly in Praj’s extensive customer base. The development work is expected to build upon the PDP that Gevo already has developed for corn, translating it to other feedstocks and plant configurations.
Butamax and Gevo cross-license & settle litigation on bio-isobutanol; Butamax to lead w/ gasoline blending, Gevo w/ alcohol-to-jet
August 24, 2015
Gevo, Inc. and Butamax Advanced Biofuels, LLC, a joint venture between BP and DuPont, have entered into worldwide patent cross-license and settlement agreements, ending a patent dispute that stretches back to 2011 related to technologies for the production of bio-based isobutanol. (Earlier post.)
This settlement ends all of the lawsuits and creates a new relationship between the companies, aimed at leveraging each other’s strengths and accelerating development of competitive supply for bio-based isobutanol.
Synbio company Intrexon and Dominion partner to commercialize bioconversion of natural gas to isobutanol in Marcellus and Utica Basins
August 20, 2015
Intrexon Energy Partners (IEP), a joint venture of synthetic biology company Intrexon Corporation and external investors (earlier post), and Dominion Energy, a subsidiary of Dominion Resources, have entered into an agreement to explore the potential for commercial-scale biological conversion of natural gas to isobutanol in the Marcellus and Utica Shale Basins.
Intrexon’s proprietary methanotroph bioconversion platform uses optimized microbial cell lines to convert natural gas into higher carbon compounds such as isobutanol and farnesene under ambient temperatures and pressures. This novel approach avoids costly, resource-intensive thermochemical gas-to-liquids (GTL) conversion methods, and offers a biofuel that does not utilize sugar or other plant-based feedstock.
DOE BESC engineered microbe improves biobutanol yield from cellulose by a factor of 10
August 14, 2015
Researchers at the US Department of Energy’s (DOE’s) BioEnergy Science Center (BESC) have engineered a microbe that improves isobutanol yields from cellulose by a factor of 10. The work, published in the journal Metabolic Engineering, builds on results from 2011 in which researchers reported on the first genetically engineered microbe to produce isobutanol directly from cellulose. (Earlier post.)
Isobutanol is attractive because its energy density and octane values are closer to those of gasoline; it is useful not only as a direct replacement for gasoline but also as a chemical feedstock for a variety of products. For example, isobutanol can be chemically upgraded into a hydrocarbon equivalent for jet fuel.
National Marine Manufacturers Association endorses use of isobutanol in marine fuel market
June 18, 2015
The National Marine Manufacturers Association (NMMA) has identified biobutanol as a suitable and safe alternative biofuel to ethanol. The research and subsequent resolution to move forward formally with butanol as an industry-wide biofuel alternative comes as the industry focuses on addressing the congressionally-mandated Renewable Fuel Standard (RFS) requiring 36 billion gallons of renewable fuel to be blended into the gasoline supply by 2022.
Methods to increase renewable fuels in the gasoline supply have primarily focused on ethanol—specifically fuel with a higher blend of ethanol such as E15 (fuel with 15% ethanol). Multiple reports show that ethanol blends greater than 10% can cause significant damage to marine engines. As a result, the marine industry has explored biobutanol fuel blends with promising results.
DOE BETO awards $10M to 7 advanced biofuels projects
February 21, 2015
The US Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) has selected seven projects to receive up to $10 million to support innovative technologies and solutions to help advance the development of advanced biofuels, including bugaboo and drop-in hydrocarbons.
The Bioenergy Technologies Office is working to produce cost-competitive ($3/gallon of gasoline equivalent) advanced biofuels from non-food biomass resources that reduce greenhouse gas emissions by 50% or more versus petroleum-based alternatives. These newly selected projects are intended to support this effort.
