Global Bioenergies, IBN-One and Lantmännen Aspen partner on renewable isooctane for specialty fuel applications
July 11, 2016
Global Bioenergies, IBN-One and Lantmännen Aspen, world market leader in alkylate gasoline for two- and four-stroke small engines, have entered into a partnership on renewable isooctane (earlier post) for specialty fuel applications.
Aspen is part of the Swedish Lantmännen group, an agricultural cooperative and Northern Europe’s leader in agriculture, machinery, bioenergy and food products with annual revenues of €3.4 billion (US$3.8 billion). In particular, Lantmännen Aspen’s commercial activities include specialty fuels for usage in two- and four-stroke small engines—e.g. chainsaws and lawn mowers—where the operator, machine and environment benefit from a cleaner fuel quality regarding harmful substances compared to regular gasoline.
Global Bioenergies obtains a €400K grant from BMBF to produce renewable gasoline additives; Audi to use for engine testing
July 04, 2016
France-based Global Bioenergies announced that its German subsidiary, Global Bioenergies GmbH, secured a €400,000 (US$446,000) grant from the BMBF (the German federal ministry for research and education) to finance a 14-month-project aimed at producing renewable gasoline additives.
Global Bioenergies has developed a process to convert renewable resources into gaseous isobutene via fermentation. Under the new grant, Global Bioenergies will first produce 100% renewable ETBE, a molecule obtained by the condensation of ethanol and isobutene, and presently used as a gasoline additive in large volumes (worldwide market: 3.4 million tons per year).
Altex & Unitel partner to demonstrate a new technology for making synthetic gasoline from biomass
April 05, 2016
Altex Technologies has selected Unitel to provide engineering services to design and build a pilot system that will produce 1 BPD of synthetic gasoline from biomass (Biomass Conversion to Synthetic Gasoline System, BCSGS). This project is funded by a ~$1-million grant from the California Energy Commission under the auspices of its Alternative and Renewable Fuels and Vehicle Testing Program.
The Altex process does not require the intermediate conversion of the feedstock into synthesis gas or pyrolysis liquids, plus it does not require hydrogen. Some of the feedstocks that Altex plans to use include alfalfa, corn stover, switchgrass, and processed woodchips.
NREL updates Survey of Advanced Biofuel Producers in the United States
March 17, 2016
The National Renewable Energy Laboratory (NREL) updated its annual survey of US non-starch ethanol and renewable hydrocarbon biofuels producers. The 2015 Survey of Non-Starch Ethanol and Renewable Hydrocarbon Biofuels Producers provides an inventory of the domestic advanced biofuels production industry as of the end of calendar year 2015, documenting important changes (e.g., biorefinery development, production capacity, feedstock use, and technology pathways) that have occurred since the publication of the original 2013 survey.
During 2015, NREL surveyed 114 companies that were reported to be pursuing commercial-scale biofuel production capacity. Companies were classified as either non-starch (cellulosic or algae-derived) ethanol producers or renewable hydrocarbon producers. The questionnaire included topics such as facility stage of development, facility scale, feedstock, and biofuel products. The NREL team supplemented missing survey data elements (when possible) with publicly available data obtained directly from company websites, press releases, and public filings.
USPTO awards patent to UMD team for process to make gasoline through fermentation; electrofuels
December 22, 2015
The US Patent and Trademark Office issued patent Nº 9,217,161 for a process using naturally occurring microorganisms to ferment biomass or gases directly to hydrocarbons such as hexane and octane. The fuels separate and rise to the surface of the fermentation broth, and are exactly the same as current components of gasoline.
The inventors are Professor Richard Kohn and Faculty Research Associate Dr. Seon-Woo Kim from the University of Maryland (UMD). The team was awarded a separate patent earlier this year (9,193,979) for ethanol-tolerant microorganisms that convert cellulosic biomass to ethanol. (Earlier post.) Both processes were developed based on their theory, described in in a paper published in the Journal of Theoretical Biology, that fermentation systems drive toward thermodynamic equilibrium.
Ensyn granted EPA Part 79 approval for renewable gasoline
November 25, 2015
Ensyn (earlier post) has been granted a key regulatory approval from the US Environmental Protection Agency (EPA) for its renewable gasoline product, RFGasoline. This approval, pursuant to Title 40 CFR Part 79 promulgated under the Clean Air Act, is required for the sale of RFGasoline into US commerce.
This approval follows the recently announced Part 79 approval of Ensyn’s renewable diesel product, RFDiesel. (Earlier post.)
Neste files patent on gasoline fuels with high bioenergy content
August 22, 2015
Neste, currently largest producer of renewable drop-in fuels (primarily diesel) with its NEXBTL platform (earlier post), has filed a patent (US20150144087) on a gasoline composition (and the method for making it) comprising up to 20 vol% (preferably from about 10-15 vol.%), of paraffinic bio-hydrocarbons originating from the NEXBTL process.
In addition, the fuel can incorporate oxygenates such as ethanol (5 to 15 vol%); iso-butanol (5 to 20 vol%, preferably about 10 to 17 vol%); or ETBE (7 to 25 vol%, preferably about 15 to 22 vol%). The resulting fuels with high bioenergy content can be used in conventional gasoline-fueled automotive engines. In a related paper published in the ACS journal Environmental Science & Technology, a team (Aakko-Saksa et al.) from VTT Technical Research Centre in Finland and Neste showed that a combination of ethanol or isobutanol with bio-hydrocarbon components offers an option to reach high gasoline bioenergy content for E10-compatible cars.
New one-pot process to produce gasoline-grade biofuel from the bacterial biopolymer PHB
August 09, 2015
A team from the Hawaii Natural Energy Institute, University of Hawaii at Manoa is developing a new one-pot process to produce gasoline-grade (C6–C18) hydrocarbon oil from polyhydroxybutyrate (PHB)—an energy storage material formed from renewable feedstock in many bacterial species. In contrast to conventional biofuels derived from plant biomass, the resultant PHB oil has a high content of alkenes or aromatics, depending on the catalyst.
PHB has already been identified as having great potential as an intermediate in the production of hydrocarbon fuels. One approach, described by a team from the National Renewable Energy Laboratory (Wang et al.), is thermally to depolymerize and decarboxylate PHB at 400 ˚C to propene, for subsequent upgrading to hydrocarbon fuels via commercial oligomerization technologies.
