Biofuels are increasingly lumped into a single category of environmentally apocalyptic dead-end solutions. As the food vs. fuel debate rages on, it’s no wonder that the general public believes this.

But not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.

Homemade ethanol guru Floyd S. Butterfield and Silicon Valley entrepreneur and innovator Thomas J. Quinn want to see you making ethanol in your backyard. Their creation, called the E-Fuel 100 MicroFueler, is a stacked washer-dryer sized reactor that can convert sugar into ethanol for (they claim) $1.00 per gallon.

Before you get too excited, please note that the unit is probably too expensive for your next block party, unless you’ve got an extra $9,995 lying around somewhere. Fortunately, state and Federal tax credits can halve this, but that still keeps it out of the price range of the average American. Read the rest of this entry »

Converting the nation’s vehicle fleet to run on 85% ethanol (Flex-Fuel) may have gotten a whole lot easier.

AAMCO, one of the world’s largest chains of automotive service centers, has started an initiative designed to promote environmental sustainability and energy efficiency across the nation.

The Eco-Green Auto Service initiative will certify automotive centers that meet a stringent set of criteria while adding services that cut emissions, improve mileage, and reduce hazardous waste associated with owning a vehicle.

AAMCO is also promoting alternative fuels by installing E85 conversion kits that allow vehicles to run on ethanol blends up to 85%. Their service centers will use kits provided by Flex Fuel US ®, called the FLEX-BOX SMART KIT™, which is the only ethanol conversion kit fleet-certified by the EPA.

Scania (part of Volkswagen) builds modified, heavy-duty diesel engines designed to run on almost pure ethanol (E95, or 95% ethanol, with a 5% ignition improver).

If that sounds weird, that’s because it is. US auto manufacturers make a big deal out of converting cars and trucks to run on ethanol/gasoline blends of up to 85% ethanol. Scania has done better than that for 15 years, and guess what, their engines can run on 100% biodiesel too, without any modification. Read the rest of this entry »

As Green Car Congress reported earlier this week, ethanol production is up 37% for the first quarter of 2008.

Ethanol plants in the US are now pumping out approximately 21.4 million gallons of corn-based ethanol every day, which has already amounted to 1.9 billion gallons for the year.

The upshot of all this production is progress toward the ethanol quotas required by the new Renewable Fuels Standard, which mandates 15 billion gallons of ethanol be produced from corn in the US by 2015.

But check this out: the Renewable Fuels Association estimates that in 2015 it will take 1/3 of the total US corn harvest to meet those quotas. The estimation is based on producing 3 gallons of ethanol from one bushel of corn, and a total corn harvest of 15 billion bushels.

There’s always a better whey.

A Wisconsin cheese producer, Joe Van Groll of Stratford, Wisconsin, has a way with whey.

For nearly a decade, Van Groll experimented using the waste product of cheese manufacturing, whey permeate, to manufacture ethanol. During the past four years, he’s been doing just that, and believes his process can produce ethanol for less than $1 a gallon.

Researchers at Michigan State are trying to get corn-stover to digest itself after harvest. Doing so would mitigate the costly pretreatment steps needed for the production of cellulosic ethanol from the non-edible parts of the corn plant.

MSU’s scientists are adding genetic material to the corn’s genome, genes that would normally be responsible for the digestive enzymes produced by fungi and the microbes in cow rumens. The newly transgenic plants store these enzymes in vacuoles in the leaves and stalk in a way that doesn’t affect the plant while it’s alive.

Would I put you on? It’s true, algae-based biofuels are being produced from CO2 emitted from smokstacks.

It’s happening through a company called GreenFuel, headquartered in Cambridge, Mass.

GreenFuel has been partnering with Arizona Public Service Company to create biofuels from algae grown using carbon dioxide (CO2) emissions from a power plant. The companies successfully grew algae at APS’ Redhawk natural gas power plant in Arizona, and is moving their tests to a coal-fired power plant at Farmington, NM.

According to a release from APS, algae at Redhawk grew at levels 37 times higher than corn and 140 times higher than soybeans, which are now used to create biofuels. Read the rest of this entry »

There’s no doubt that growing corn-based ethanol has some serious problems: the dead zone in the Gulf of Mexico, controversy over increasing food prices, and questionable energy return.

But how does the impact of ethanol production compare to not doing anything?

Last week, the Delta Farm Press picked up on a statement made by Texas oilman T. Boone Pickens. Pickens admitted that he has opposed ethanol in the past, but on the other hand couldn’t support exporting half a trillion dollars—something the US will do this year in order to satisfy its oil addiction. Pickens said (via Delta Farm Press):

In case you didn’t know, the “dead zone” isn’t just a novel by Steven King or an old TV show, it’s an area about the size of New Jersey in the Gulf of Mexico that during the summer months is incapable of supporting sea life. The dead zone is created when fertilizer run off promote algae growth, which in turn throws off the oceans equilibrium by using all the available oxygen, killing everything else. So, good for algae perhaps, but bad for the sea life in general.

Carectomy recently reported that ethanol production for passenger vehicles could be responsible for a growth in this dead zone. In their words:

Corn is the biggest culprit in creating these environments, and now that the U.S. is looking to biofuels as a solution to its energy needs, the problem’s only getting worse. Bush signed legislation at the end of 2007 that will triple the amount of corn ethanol produced over the next several years.

More after the jump!
