A professor at the Tokyo Institute of Technology claims to have developed a catalyst that can cut the cost of making non-food based cellulosic ethanol — “celluline,” as I like to call it — by 30%.

Just for grits and shiggles, let’s say that when celluline’s finally produced in commercial amounts it will cost consumers $3.00 per gallon. If the cost savings associated with this catalyst were passed on to consumers, that would mean the same celluline would cost $2.10 per gallon.

Professor Michikazu Hara says the carbon-based catalyst can be made cheaply, and works by breaking down cellulose and creating sugar when mixed with water and heated to 100° C. Using the current celluline production methods, this step in the process uses a large amount of energy, time and chemicals.

According to the Nikkei Business Daily (via Tradingmarkets.com), Japan’s Suzuki Motor Company will begin selling cars that run completely on 100% ethanol in the US and Brazil by 2010. The company will begin the transition by first offering an E25 sedan for sale in Brazil this coming March.

Currently the most ethanol that a flex-fuel car can run on in the US is E85 — which is an 85% ethanol/15% gasoline blend. Suzuki’s move would mark a huge development in ethanol-powered vehicles, and a huge shift for Suzuki, which hasn’t had any alternative fuel-specific offerings in its lineup to this point.

Dutch firm Green Fuel Systems, along with several other companies, has developed flex-fuel conversion kits for the Toyota Prius that cost less than $1,000. Converting our existing fleet to second-generation ethanol could be the best near-term play to directly replace fossil fuels.

Although the concept of a hybrid/biofuel combo has been around for a while, it has (at least in our minds) mostly been in the form of diesel hybrids running on biodiesel (which isn’t going to happen). But what if we could take America’s most fuel efficient car and convert it to run on another domestically-produced renewable fuel: cellulosic ethanol?

Researchers at the University of California, Davis have developed an easy, efficient and inexpensive method for transforming raw plant material directly into a fuel called furfural without any fermentation. Furfural can be substituted for diesel.

The current, most widely adopted process for making second generation cellulosic fuel — “celluline” — involves the use of acids, enzymes and fermenting microbes to get from the harvested plant material to a fuel that is usable in your car’s engine.

Sheesh. It seems that everybody and their brothers are ethanol experts these days. But what drives me nuts is that when people are talking about ethanol, they don’t seem to know what type of ethanol they’re talking about.

It’s sad because the widespread misinformation and misunderstanding is killing popular opinion for biofuels in general right now and, in particular, mercilessly destroying the good name of the second generation of ethanol — cellulosic ethanol.

The truth of the matter is that cellulosic ethanol will be made from non-food sources (miscanthus, switchgrass, wood waste, and even garbage) that can be grown on marginal land or is already a waste byproduct of society.

The production of cellulosic ethanol could have huge benefits beyond energy independence:

It seems that BP is trying to make up for lost time — the worldwide oil giant has invested $90 million in cellulosic ethanol company, Verenium. This is BP’s first foray into the world of cellulosic ethanol (ethanol derived from non-food crops), and man is it a gigantic one.

The money will be distributed to Verenium over the next 18 months, with a likelihood of further investment and cooperation beyond that point. Under the agreement, BP will have broad access to Verenium’s research, production facilities, and technology.

Although relatively late to the fray, BP thinks this investment gives them the “most advanced technology for transforming [cellulosic material] to biofuels,” as Sue Ellerbusch, president of BP Biofuels North America said.

Verenium claims to have the edge in cellulosic ethanol production through genetic engineering of the microbes required to turn the cellulosic material (switchgrass, wood chips, sugarcane bagasse, miscanthus) into ethanol.

Imagine a grass crop, grown on marginal, non-food bearing land without pesticides or much fertilizer, that, when harvested, produces an oil that needs almost no processing to be substituted for diesel fuel.

Much attention has been given to producing ethanol from non-food crops like grasses, but the ability to produce something indistinguishable to diesel from grass could be a game-changer. It would require almost no infrastructure change and could fuel all of the existing long-haul trucks on the road without modification.

Ceres, Inc. supports the prediction that we could grow more than 30% of US transportation fuel with dedicated energy crops. This is no pipe dream: planting starts next spring.

Ceres, Inc., the self-described “energy crop company,” is engineering plants that could play a big role in the future of sustainable biofuels. In stark contrast to food crops, what Ceres is in the business of creating are “dedicated energy crops”—like switchgrass, sorghum, and miscanthus—that are ideally suited for fuel production.

While the global “food vs. fuel” debate rages on, a few companies like Ceres are quietly moving forward with next generation technology that challenges many of the current assumptions about growing fuel. In their view, it’s time to move the conversation on from corn-based controversy to second-generation, non-food based sources of ethanol.

Okay. Let me get this one out of the way: gas hasn’t been all bad. In fact, gas has allowed us to accomplish some pretty amazing things. To be clear, when I say “gas,” I’m using the term as an easy way to loosely refer to all liquid fuel products made from buried and fossilized hydrocarbon deposits.

Ooooh… I can hear the flamers’ keys clicking away furiously already. But, before you type that horribly thought out gunslinging response, hear me out.

Tomorrow, General Motors is hosting a backgrounder on cellulosic ethanol feedstocks at the Thousand Oak (CA) based laboratories of Ceres, Inc.

Coverage of non-food based ethanol tends to focus on fuel production technologies, but Ceres works one step further up the supply chain: they’re using genetic technology to engineer plants optimally suited for conversion into something you’d want to put in your gas tank.

I’ve already had the chance to speak with Richard Hamilton, President and CFO of Ceres, about the potential to produce super-strains of perennial grasses like sweet sorghum and switchgrass, and I’m looking forward to hearing more details tomorrow.

The current rate at which biofuels are falling out of favor is largely founded on biased ideologies, which have been shaped by widespread political and corporate agenda-pushing from all sides of the fence.

But first, a digression.

Part 1: When an egg was just an egg

I remember a time when an egg was just an egg. Nobody argued about that. It was a blissful time. Yet, for all its strengths, it was a fragile time held together by unsupported conclusions and limited knowledge.
