On the heels of the opening of Coskata’s first flex ethanol facility capable of making ethanol from virtually any organic material, GM and Coskata have released a video (below) detailing the Coskata process. Unlike most promotional/informational videos that get dumped on the public, this one is actually rather informative.

Pennsylvania is beautiful this time of year, but I missed most of it since I made the 400+ mile drive mostly in the dark. It took eight hours of dodging speeding semi-trucks and going through many miles of tunnels, but I finally made it to the Westinghouse Plasma Center in Madison, PA. In case you’re asking, yes, the same Westinghouse that makes flat screen televisions (among other nifty tech stuff).
The Coskata semi-commercial flexible ethanol plant, dubbed “Lighthouse”, is located here. This facility is essentially a working scale model of a full size ethanol plant, and the processes and technology here can one day soon be scaled up to produce as much as a 100 million gallons of flex ethanol annually. The important word here is flexible, because unlike other ethanol products, the Coskata process can use just about any carbon matter to produce ethanol. This means the very garbage filling our dumps may one day instead fill our cars.

With the attention on first generation corn ethanol fading, the next big thing on the sustainable fuel horizon is nonfood biofuel crops. Within that category, inedible weeds are taking a front-row seat due to their relatively low demands on water, pesticides, and herbicides, and their reduced need for tilling and other mechanized soil prep. Some weeds with biofuel potential can also thrive on contaminated soils, absorbing and cleaning pollutants in a process called phytoremediation.

Needed is fuel from wood and waste, not food and haste. Some of the world’s best minds are focused on fuel from cellulosic and waste sources, in some cases from biological sources that remove CO2 from the air and enrich depleted soil. I am writing this article from the 31st Symposium on Biotechnology for Fuels and Chemicals sponsored by NREL. 800 global bioscientists have gathered in San Francisco to share their research and showcase their progress. Many at the conference [...]

The 31st Symposium on Biotechnology for Fuels and Chemicals
One of the world’s most prestigious and established biofuels meetings, the 31st Symposium on Biotechnology for Fuels and Chemicals, is currently underway May 3-6 in San Francisco, with more than 800 scientists expected to attend sessions on topics ranging from commercialization of biofuels and their long-term sustainability to emerging technologies and turning algae into fuel.
We’re liveblogging (on Twitter) [...]

We must transition from fuel from food and haste to fuels from wood and waste. Although the economics do not yet favor major production, pilot plants are taking wood and paper waste and converting it to fuel. Other cellulosic material is even more promising. Some grasses , energy crops, and hybrid poplar trees promise zero-emission fuel sources. These plants absorb CO2 and sequester it in the soil with their deep root systems.

Alan Novak, Director of Alternative Fuels for Emerson Process Management and host of at least three BioEnergy Summits throughout the country, is optimistic for the future of advanced biofuels in meeting the nation and the world’s future transportation fuel needs.

It is well-known, of course, that the rich and their descendants will be completely immune to the effects of climate change. Thus, many of them have been driving efficiency-challenged cars that carelessly drain the last of the world’s oil, making their carbon footprint heavier than that of lesser beings.
So, from a climate-change point of view, who better to target with the security of their own driveway supply to power their gas guzzlers — from a carbon free fuel in place of oil? The I’ve got mine crowd.
Everyone who drives gas guzzlers could recoup the cost in a bit over a year. How?
Because this home ethanol distillation unit-cum-driveway pump invented by the Los Gatos company E-Fueler can distill ethanol from a nearly free feed stock; waste alcohol from vineyards or restaurants.

If non-food cellulosic ethanol — “celluline” — is the future of sustainable biofuels, what are the best non-food crops to use to make it?
In a new study, researchers have shown that growing perennial grasses to make celluline rather than using corn stover or sugar cane is better for the environment because it increases soil health and stores much more carbon in the soil, thereby reducing greenhouse gases.

Current first generation ethanol is produced by fermenting the starch in corn kernels. This has become a controversial source of biofuel due to food vs. fuel concerns and the relatively low energy gain from the whole process.
But celluline represents a true departure from these concerns in that significantly more liquid fuel energy can be harvested from non-food portions of the plant — the stems and leaves. Celluline is still in the research and development stage, but many people have hung their hats on it as the holy grail that will replace corn ethanol and bypass concerns over food vs. fuel and energy gains (PDF).

Tom Vilsack — former two-term Governor of Iowa, strong biofuels supporter, and former democratic candidate for president himself — has been leaked as President-elect Obama’s frontrunner for Agriculture Secretary.
From a biofuels standpoint, the choice of Vilsack would be a clear indication of the direction an Obama administration would likely take. As a political leader from a corn farming state, Vilsack has shown strong allegiances with the corn ethanol industry in the past and has been an outspoken advocate of alternative energy.
