Yeah, But Tesla Is So Much Cooler

Availability options for ethanol are spinning the wheels of the industry.

by Jeff Reinke, Editorial Director, PD&D

Jeff ReinkeAt the risk of losing my membership card in the middle class, white republican club, I’m going to go out on a limb and admit that I like the technology and environmental benefits of E85, as well as its soon to be developed ethanol brethren, as a fuel source for my vehicle. However (cue the Evil Galactic Empire music that marks Darth Vader’s entrance), I rarely use it because of the cost disadvantages, and I’m not alone.

Although I may be one of the few to vocalize my stance, I’m confident of my presence in the silent majority after both a conversation with Luke and Carrie following their attendance at the opening of Coskata’s new cellulosic ethanol facility, and in reading a post on www.biofuelsdigest.com regarding a study that compared an E85 flex fuel vehicle with the all-electric Tesla Roadster.

Coskata feels their plant and proprietary process will result in lower processing costs and higher fuel octane levels, but unfortunately this still doesn’t solve the distribution and accessibility roadblocks associated with ethanol—which is why the dark side of the force still drives my purchasing rationale.

Then there’s the Biofuels Digest study. According to which, a vehicle running on E85 corn-based ethanol generates 30 percent fewer CO2 emissions over its lifetime when compared to the Tesla all-electric sports car. This is based on the amount of coal that needs to be burned in order to generate the electricity coming via the plug.

Using this same logic, the Tesla will also create 21 percent more CO2 emissions than a car running on conventional gasoline. Additionally, other ownership issues, like a higher initial cost and having to replace a $12,000 lithium-ion battery, would seem to make a vehicle using E85 or any other variation of ethanol, a better option.

So armed with this type of knowledge, why did the U.S. Department of Energy provide Tesla with a $465 million low-interest loan, and offer potential buyers with tax credit incentives of up to $7,500?

Simple. The Tesla has a better chance for greater public acceptance.

Even though it strains the national grid and complicates environmental controls, electrical outlets are everywhere. There’s no issue with plugging in/refueling the Tesla. I have to go out of my way to fill up on E85, and then I know that I’d have to go back to re-fill sooner because of the lower energy density. So the cost savings are mitigated because I’m buying more fuel, simply at a lower price.

At the end of the day a cool looking sports car that I can plug in to an outlet in the garage is going to get more momentum and change more attitudes than hunting and searching for an ethanol pump that I’ll have to frequent more often with basically the same, old boring vehicle I’m driving now.

I like the cleaner element of ethanol. I like the fact that more feedstocks based on current waste products can be used to produce it. I even like the fact that it makes a hardcore conservative like me think a little greener. However, until the availability options for ethanol are solved, I’m afraid this segment of our industry is simply spinning its wheels.

Is ethanol-blended fuel just an inconvenient stepping stone on the path to electic vehicles? Drop me a line at jeff.reinke@advantagemedia.com.


Jeff - Good discussion and well phrased.

Food for thought: Why use food to make fuel? Using waste to produce fuel is an excellent idea and should be pursued, but using corn (or any other food) is not economically justifiable. And on the distribution side, why not take waste bio-fuels and our large supply of natural gas (and other "green" sources) to generate electrical power for which we have a good distribution system - and then enjoy driving that Tesla? Or using your electric mower or garden tractor? For vehicles, significant gains in efficiency can be made with hydraulics and should be encouraged more - including retrofit kits for the large number of pickups in use.

I agree that E85 is not the smartest program that they could come up with, but the farmers that they used to pay not to grow can now grow and sell, at a fixed rate, for E85. Um, but if they didn't grow but now they do, doesn't that mean more emissions from diesel equipment to plant, till, and harvest? Shouldn't that go into their one sided equasion? Don't like coal? What about hydro power generation? Solar has been being "developed" for 40 years and has made no progress, despite a long history of government funding. We, as a whole, need to re think our past decisions and regulations in order to progress to a viable, affordable, safe, clean future.
The distribution argument doesn't hold water either. They completely removed and rebuilt a gas station in the next town in two weeks. The state built a propane station, for municipal vehicles, on a local vacant lot in a month. Ever see the Army Corps of Engineers build a bridge over a river in 12 hours? It can be done if it needs to be.
As a boy I built a VW that got 50MPG with standard VW parts. Today they have electronic controlled fuel injection and computer controlled systems. I once worked on a vehicle that used a 24VDC aircraft starter for a motor and golf cart batteries for power. It had a hand wound rheostat for a throttle and would go 60 MPH with a 200 mile range. The year was 1974. C'mon people, who's kidding who.

Ethanol is a very unstable fuel, it will spoil in a matter of weeks! It is just a diversion by the big oil companies to make alternative fuels seem less viable.
Electric vehicles can charge bateries from wind and solar genarated electricity too! Comparing the emmisions to electricity generated by coal power is a serious slant on the issue!
Hydrogen fuel cells will be the only viable alternative fuel fo the future fleets of commuter cars. Check with any large auto maker, and you will see that these are the designs on the not to distant horizon. Before you start dishing any BS on the dangers of hydrogen, remember how flammable gasoline is? Hydrogen for fuel cells can be generated with solar pannels at a minimal cost, and storred as safley as propane.
Excelent rebuke on the distribution debate! Let's sink the E85 and look to serious allternatives.

Hydraulics is the most viable quick fix, while infrastructure changes are made. Let's see more of the government fleets testing these options, so we can get some hard data, rather than all this conjecture and propoganda!

Hydrogen is only useful in a easily transportable form (i.e. liquid) which does not mean cooled and compressed H2 (terribly inefficient) but NH3(liquid anhydrous ammonia). First make H2 (nuclear electrolytic, PV solar electrolytic, or solar-thermal H2O decomposition via, a.e.; a S/I cycle) then convert to NH3 via a Haber–Bosch process type catalytic process with N2 derived from air separation techniques). Some new direct electrolysis; H2O + N2/air to NH3 generation methods are in development. NH3 can be combusted, decomposed to N2 & H2 for a fuel-cell or directly to a (also in development) NH3 to electricity fuel-cell.
