Tomorrow and Friday, GM is hosting a biofuels seminar in Chicago. We'll be bringing you full coverage from the Windy City, but before we head over, we wanted to check up on what Coskata has been up to, considering that our friend Wes Bolsen will be on hand and we'll get an update directly from him. The company hasn't put out any press releases since April, but that doesn't mean nothing has happened.

Greentechmedia mentioned that the biofuel company should be just about finished with a third round of funding, which will probably be a big one. On top of a $25 million demonstration plant being built in Pennsylvania, Earth2Tech writes about a new $400 million Coskata plant in Florida in partnership with U.S. Sugar Corp. Whatever the general discussion is in Chicago, we'll make sure to get the official response from Coskata to these claims that there's simply no way they can make cellulosic ethanol for $1 a gallon. Stay tuned.

General Motors and Coskata today announced that a pilot plant for cellulosic ethanol will be built in Madison, Pennsylvania. The plant will located adjacent to the Westinghouse Plasma Center in Madison. The plasma torches that Coskata will be using for their gasification process are based on technology that was developed by GM and Westinghouse in the early eighties. At that time the companies developed a plasma furnace used to melt raw materials for cast iron production at GM foundries. The first production application was at a GM foundry in Defiance OH in 1989.

Coskata is using the same plasma torch technology to heat biomass materials to over 1,600 degrees Fahrenheit. That temperature is sufficient to convert almost any organic matter into a gas that is an intermediate ingredient in Coskata's process for producing cellulosic ethanol. Coskata's pilot plant will use Westinghouse Marc-3 plasma torches while the commercial scale plant will use larger Marc-11 torches. The pilot plant will be in operation in Q1 2009 with the first commercial plant following in 2011.

When Coskata came out of stealth mode in January, the company announced that a 40,000 gallon-per-year commercial demonstration plant using a proprietary microbial cellulosic ethanol production process would be in operation by the end of 2008. Greentech Media reports that the biofuel start-up has begun construction on this demo plant, but we still don't know where. The location should be announced later this month, and the fuel from the plant will be used by GM at the Milford Testing Grounds and, possibly, by NASCAR. Coskata chief marketing officer Wes Bolsen also told Greentech Media that the tiny test lab at the company's Warrenville, Illinois location has helped double the efficiency of the ethanol-producing microorganisms since January. By late 2010-early 2011, a 100-million-gallon-per-year plant should be operational and a number of firms are bidding on the right to build it.

The magical cost of $1 per gallon of cellulosic ethanol is certainly a hot calling card these days, and one of the most well-known purveyors of this story is Coskata. Coskata splashed onto the scene in January with the big GM announcement, and has stayed in the news by announcing a partnership with ICM and, later this month, will disclose the location of its 40,000 gallons a year demonstration facility.

Bill Roe, the Coskata CEO, gave C-Net's Michael Kanellos an explanation yesterday of just how his company will be able to make this greener ethanol for that low a price. The short version is that Coskata's plan to license it's technology to bigger companies (companies that already know how to effectively build large ethanol plants), it's ability to use pretty much any carbon-containing item as a source for the fuel and it's mixed approach (one that contains both biological and thermochemical processes) to making ethanol all add up to a plan that, at this point, makes cheap cellulosic ethanol seem reasonable. Read the full details over on C-Net.

According to this tiny news posting, the cellulosic ethanol biotech team over at Coskata has raised $19.5 million in Series B funding (series B funds are made in the second round of investment in a private company). Whether that money includes the undisclosed amount GM put into the company earlier this year is unclear. I went hunting for the original regulatory filing where Private Equity HUB claims they found the information, but couldn't track it down. Coskata has not yet released an official statement about the funding, but PE says that backers named in the filing include Globespan Capital Partners, General Motors, Khosla Ventures, GreatPoint Ventures and Advanced Technology Ventures. The new name in the Coskata-backing lineup is Globespan.

When AutoblogGreen visited Coskata's Chicago headquarters, we didn't get into details about just how ordinary (in a 21st century American suburban business park kind of way) the surrounding area looked. Cars.com's description of their visit, though, starts off by questioning whether this potential energy leader's location is fitting for such important work:

... could [Coskata] really be found in a cluster of lookalike buildings housing an advertising agency, a medical clinic and a company called Yum Brands[?]

The answer is yes, and Cars.com goes on to describe why corn ethanol is a bad idea (actually, a "much, much worse idea" than we previously thought) and then describes a bit of Coskata's cellulosic ethanol production process. This should be a recap for those of you who read our initial report on what GM and Coskata are cooking up, but if you're hungry for more viewpoints on what Coskata is all about, it's worth a read.

If all the AutoblogGreen coverage of the GM-Coskata cellulosic ethanol partnership wasn't enough to satisfy your curiosity about just how these two companies hope to make living green and going yellow that much better for the environment (at least until Coskata gets into the coal-to-ethanol stuff, which a lot of us have questions about), Green Fuels Forecast has a few videos for you. In the clip above, GFF talks with Coskata's Richard Tobey about the technical aspects of the syngas-to-ethanol process.

After the jump, you'll find video interviews with various GM and Coskata representatives (Coskata CEO Bill Roe and GM's Mary Beth Stanek and Candace Wheeler) as well as a DieselForecast interview with the CEO of BMW USA, Tom Purves. Purves talks about how BMW plans to introduce diesel engines to the U.S. market.

General Motors vehicles and biomass materials are two things that you can find pretty much anywhere on the planet. GM and Coskata Energy announced a partnership today at the Detroit Auto Show that certainly hints at a future where you we will find biomass materials fueling GM vehicles in a lot of places, maybe pretty much anywhere.

If you've heard the Coskata name before, it's likely from the name of the Coskata-Coatue Wildlife Refuge. The Coskata energy company, no relation, was started in July of 2006 with funding by ethanol-magnate Vinod Khosla's Khosla Ventures as well as Advanced Technology Ventures and Great Point Ventures. Why was all this big money interested in Coskata? Because Coskata claims they will soon reach one of the holy grails of the new energy movement: cheap cellulosic ethanol that can be created, well, pretty much anywhere in the world. The short version of this story: Coskata Ethanol can make ethanol from biomass, municipal solid waste and any other carbon-containing material and GM, which has taken an equity stake in Coskata, wants to promote the heck out of this ability.

More details than you can possibly devour in one sitting after the jump.
