Gevo announced this week that it is getting closer to its goal of having 350m gal/year isobutanol capacity by 2015 with its recent investment in another ethanol plant owned by its new joint venture partner Redfield Energy of Redfield, South Carolina.
The 50m gal/year ethanol plant will be retrofitted around late 2011 by Gevo to produce 38m gal/year bio-isobutanol, which is expected to start commercial production by fourth quarter of 2012.
Gevo said it will provide the technology and capital to retrofit the facility in exchange for equity interest in Redfield. The companies did disclose how much capital will pour into the facility.
I will actually write an article about bio-based chemical intermediates used in rubber manufacture and hopefully will be able to talk to Gevo as well as its investor/partner Lanxess on their isobutene project. One of my question is how much isobutanol per year Lanxess needs from Gevo to satisfy their demand for isobutene, that will be used to produce biobased butyl rubber.
Gevo is currently retrofitting another 22m gal/year ethanol plant, which it bought in Luverne, MN, to produce 18m gal/year bio-isobutanol slated to start in the first half of 2012.
