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.
For the moment, the price at the pump is reasonable. A spike in demand or a terrorist disruption, however, will quickly remind us that we are desperately dependent on oil as we continue to consume 140 billion gallons of gasoline per year. Even in these recessionary times of moderate demand, we are running out of easy to extract oil from dessert sands. We are turning to sources of unconventional oil, such as tar sands in Canada, to produce oil with ever increasing greenhouse gas emissions.
For a while, corn ethanol was viewed by some as a step in the right direction. Now we are like the character in a Woody Allen comedy who explains, “I used to be a heroin addict; now I’m a methadone addict.” At a time when a billion people go hungry, many as a result of disappearing water on this heating planet, fuel from food is not the answer.

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) from today’s press meeting for the event.

The 9 billion gallons of ethanol that Americans used last year helped drive down oil prices. For those of us who fuel our vehicles with gasoline, as much as 10 percent of that gasoline is ethanol. The Energy Independence and Security Act of 2007 requires that more biofuel be used every year until we reach 36 billion gallons by 2022.
Reduced oil prices are good. We can go from good to great, if we move past 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. These plants often grow in marginal lands needing little irrigation and no fertilizers and pesticides, standing in sharp contrast to the industrial agriculture that produces much of our fuel.

Cellulosic ethanol is, for some, the holy grail of alternative fuel, while others remain resolutely unconvinced, claiming such confidence in the potential of biofuel as a fool’s errand (or worse).Beyond these entrenched extremes, ranging from wild optimism to abject skepticism, comes the real heavy lifting - understanding there are significant hurdles inherent in getting second generation biofuel from the lab into full-scale sustainable commercial production, but seeing those hurdles as challenges to be overcome, not as roadblocks from which to retreat, and working to bridge the gap from current reality to potential promise.
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.

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).
In the report, “Will the Plunge in Grain Prices Mean Lower Food Prices at the Supermarket?,” the RFA points out that, while prices for agricultural staple commodities such as corn, wheat, and soybeans have all plummeted by about 50% in the last half year, food prices at the grocery store have remained highly elevated. At the same time, ethanol production has dramatically increased.
When the above factors are taken together, the link between grocery store food prices and corn ethanol production becomes dubious. Not only that, and also somewhat unintuitively, it seems that the diversion of relatively large portions of the US corn crop to ethanol production has very little effect on even the market price of corn.
Editor’s Note: I was in Houston, TX, last week, celebrating the International Year of the Planet at the first ever joint meeting between the American societies of Soil Science, Geology, Crop Science and Agronomy. With a significant focus on biofuels, this conference was rife with interesting materials.
In my last post I discussed how agriculture could regain its rightful place as the keystone of civilization due to the rise of biofuels over the next 30 years or so. But, in what seems a ridiculously colossal conundrum, hundreds of millions of impoverished people worldwide could face starvation due to competition of fuel land with food land.
Editor’s Note: I’m in Houston, TX, this week, celebrating the International Year of the Planet by posting on topics covered at the first ever joint meeting between the American societies of Soil Science, Geology, Crop Science and Agronomy. With a significant focus on biofuels, this conference should be rife with interesting materials.
Several times during the session the presenters highlighted the fact that biofuels have finally brought an inherent value to agriculture that was previously missing. This, more than anything else, is why biofuels are not going to go away. Up to now, the lack of agricultural value has caused a deep deficiency in the level of funding and investment that governments worldwide have provided for their agricultural security and infrastructure.
Over the last few months, things have been a bit gloomy in the world of biofuels. Earlier this year, they enjoyed a position of prominence as a viable means of reducing carbon emissions and addressing the energy crisis. Since then, federal mandates requiring an increase in the amount of land set aside for growing biofuel crops may have already contributed to rising food costs and, peversely, may have also actively triggered an increase in global warming. As a result, the public and political perception of biofuels is at an all-time low.
The Sustainable Biodiesel Alliance (SBA) is a non-profit organization created to promote cradle-to-grave biodiesel practices for verifying that all points in the production and distribution chain are sustainable.
And now they want your input on what those sustainable practices and standards should be — they’ve released the first draft of their “Principles and Baseline Practices for Sustainability” (PDF) to the public under a 45-day comment and review period.
So, if you’ve ever questioned the wisdom of growing our own fuel, or you’ve wondered how biofuels can be considered sustainable at all given other seemingly cleaner options like solar, wind and geothermal, now’s your time to speak up.
