Companies

  • The EFuel100 MicroFueler™ (http://www.efuel100.com) is the world's first portable ethanol micro-refinery system; it replaces the traditional ethanol reflux column system with a solid state distillation technology, making it possible for homeowners and small businesses to safely and cost-effectively create their own fuel, on-site (available 4th Quarter, 2008).

Technologies

  • Ethanol from Garbage and Old Tires (http://www.technologyreview.com/Energy/20199/?nlid=925) - Tubes packed with bundles of white fibers are the core of a bioreactor, which is the heart of a new technology that Coskata claims combine thermochemical and biological approaches to make ethanol out of wood chips, household garbage, grass, and old tires--indeed, just about any organic material. (MIT Technology Review; March/April 2008)
  • Methanol -- Ethanol's Sister Product - Ethanol can be an even more effective energy alternative to petroleum if the unused portion of the crop are used to create methanol. (PESWiki; Feb. 26, 2006)
  • Tectane: H20 Injector and Aquahol - H2O Injector is an inexpensive add-on device for car engines which reduces emissions and increases mileage up to 40%, and can allow cars to run on 75-octane gasoline or ethanol fuels. Aquahol is the separate injection of 80% ethanol and 20% water, which is the cleanest-burning fuel. Drawbacks?
    • Tectane Offers a Net Zero Solution for Existing Vehicle Infrastructure (http://pesn.com/Radio/Free_Energy_Now/shows/2007/02/03/9700223_Tectane/) - By injecting water into an ethanol mixture that can be used on most any vehicle, and producing ethanol from the prolific and multi-use sweet sorghum plant, the net result is no added emissions to the environment. {PESN; Feb. 3, 2007}
  • Switchgrass shows promise for ethanol production (http://www.physorg.com/news118949833.html) - A large-scale trial of switchgrass suggests that prairie grasses grown using only moderate amounts of fertilizer on marginal land can produce significant amounts of ethanol, making the crop a more viable plant source of biofuel than previously thought. (PhysOrg; Jan. 7, 2008) (CBS News (http://www.cbsnews.com/stories/2008/01/09/tech/main3692251.shtml)) (Slashdot (http://hardware.slashdot.org/article.pl?sid=08/01/11/1847256))
  • Cannabis Hemp as a Global Warming Solution - Proponents argue that easily grown and robust Cannabis Hemp is one of the best if not the very best plants overall for fuel, building supplies, medicine, fiber, food, paper, and substitute for wood. Some go so far as to argue that it could be the best solution to global warming.
  • New natural gas dehydration approach (http://www.insidegreentech.com/node/797) - The Vaperma (http://www.vaperma.com/), EnCana (http://www.encana.com/) and SDTC (http://www.sdtc.ca/) Advanced Natural Gas Dehydration Project could significantly reduce emissions and energy consumption compared to traditional natural gas processing.

  • Biofuel nanotech process intensification (http://biopact.com/2007/02/nanodynamics-licences-biofuel.html) - NanoDynamics' (http://www.nanodynamics.com/) ND Fusion rotating tube reactor (http://www.ndfusion.com/processint.php) provides for faster, higher, more efficient ethanol yields by boosting fermentation without damaging fragile yeast cells and generates higher purity ethanol with lower energy and capital cost. It has the ability to economically convert sugarcane process streams to ethanol. (Biopact; Feb. 27, 2007)
  • Zeolite Membrane for Ethanol Dehydration (http://www.greencarcongress.com/2007/07/mitsui-engineer.html) - Mitsui Engineering will use a zeolite membrane in dehydration systems for bioethanol plants, to remove water from the ethanol produced. Only water passes through the membrane, thereby helping to reduce process fuel consumption by around 10% compared to other methods. (Green Car Congress; Jul. 11, 2007)
  • Biodiesel Processors and Ethanol Stills (http://www.circlebio.com/) - Circle Biodiesel & Ethanol Corporation makes biodiesel processors as well as ethanol stills for the biofuels industry. (PESN; Oct. 23, 2007)

Cellulosic

  • Is vinegar the secret ingredient for biofuels? (http://www.news.com/8301-11128_3-9891603-54.html?tag=cd.blog) - ZeaChem (http://www.zeachem.com/) says it has come up with a method of making cellulosic ethanol that results in close to 40 percent more fuel per ton of wood chips than competing processes, and at a price at the pump of around $1.10 to $1.50. See Video (http://www.news.com/1606-2_3-6233989.html). (CNet News; March 12, 2008)
  • Hydrogenolysis Process for Cellulosic Ethanol (http://www.greencarcongress.com/2007/07/mohr-davidow-an.html) - ZeaChem (http://www.zeachem.com) combines the output of fermentation and gasification into hydrogenolysis, for the production of ethanol from cellulosic biomass feedstocks. ZeaChem claims that its technology will produce 50% more ethanol per ton of feed and results in an energy output that is more than ten times greater than the input. (Green Car Congress; Jul. 2, 2007)
  • Heat-Seeking Bacteria Could Hold Key to Better Cellulosic Ethanol (http://www.treehugger.com/files/2007/08/heat-seeking_bacteria.php) - TMO Renewables (http://www.tmo-group.com/) believes it has found the silver bullet of cellulosic ethanol production: an organism that eats nearly anything and makes ethanol really quickly. The heat-seeking rod-shaped bacterium thrives in high temperature conditions and is 300 times more effective at making ethanol than its wild strain counterpart. (TreeHugger; Aug. 24, 2007)
  • Biofuels from Wood Chips (http://www.physorg.com/news100838926.html) - Three University of California campuses and West Biofuels LLC, will develop a prototype research reactor to make biofuels without food crops or microbial fermentation. It will use steam, sand and catalysts to efficiently convert forest, urban, and agricultural “cellulosic” wastes into alcohol that can be used as a gasoline additive. (PhysOrg; Jun. 12, 2007)
  • Brelsford Engineering Inc (http://www.beienginc.com/) - BEI is offering a new and efficient dilute-acid (http://www.brelsfordenginc.us/) chemical process for the conversion of waste cellulose into fermentable sugars and subsequently into bio-ethanol. Capital costs are about 50% of those for comparable dilute concentrated acid, or enzymatic, cellulose hydrolysis processing. Small farm scale fuel ethanol plants can now be economically profitable.
  • Cellulosic ethanol breakthrough (http://biopact.com/2007/05/dedini-achieves-breakthrough-cellulosic.html) - Brazil's Dedini SA (http://www.dedini.com.br/) announced it has come up with a way to produce cellulosic ethanol on an industrial scale from plant waste, at a cost of US 27 cents a liter (US$ 1.02 per gallon). This development could revolutionize the industry, making it cost-competitive with oil at US$42 a barrel. (Biopact; May 16, 2007)
  • BTX starch separation from wheat straw verified (http://biopact.com/2007/02/independent-lab-verifies-btx-holdings.html) - Starch was extracted from wheat straw with the 'Hypercritical Separation Technology' (http://www.biotexcorp.com/technologies.html), a dry mechanical system to separate biomass on a molecular level, while utilizing very little energy and emitting no waste product. The HST system concentrates the starch and sugar fractions to produce feedstock for cellulosic ethanol. (Biopact; Feb. 15, 2007)
  • First US Cellulosic Ethanol Plant (http://thefraserdomain.typepad.com/energy/2007/02/celunol_cellose.html) - Celunol (http://www.celunol.com/) achieves high ethanol yields from cellulosic biomass at costs competitive with conventional sugar and starch feedstocks. Its 50,000 gallon pilot facility commenced operation in November 2006 and a 1.4 million gallon facility is targeted for completion in mid 2007. (The Energy Blog; Feb. 8, 2007)

Its two-step thermo-chemical conversion process to convert biomass into a synthetic gas and then gas to ethanol, eliminates the use of expensive enzymes. (Renewable Energy Access; Feb. 8, 2007)
  • Mascoma (http://www.mascoma.com/) - Cellulosic biomass has a cost per BTU equivalent to oil of about $14/barrel. Recent advancements in enzymes, organisms and production technologies allow cost-effective ethanol production from inexpensive cellulosic biomass (grass, wood, agricultural and forestry wastes).
  • Diversa (http://www.diversa.com/) - Developing enzymes that convert renewable resources, such as corn and cellulosic biomass, into renewable fuels, such as ethanol and biodiesel. Valley "Ultra-Thin™" enzyme, for the conversion of corn into ethanol, is on the market today and a set of enzymes has been developed for an economical, commercial-scale process to convert starch and cellulosic biomass to fuel ethanol.
