A Thanksgiving Feast of Alternatives

/in , /by

“Over the river and through the wood

To grandmother’s house we go.

The horse knows the way to carry the sleigh\

Through white and drifted snow.”

Thanksgiving has come and gone, Christmas is coming, and that makes me think of alternative fuels and finding something to replace gasoline in our engines.

What, after all, was the horse and sleight except an old-fashioned means of transportation?  It had served humanity since the Bronze Age.  It has often been said that Julius Caesar and George Washington used essentially the  same transportation technology in pursuing their wars

All this held through the early days of the 20th century. There is a famous scene Jules Verne’s The Mysterious Island, written in 1875, where the adventurers go to investigate a mysterious submarine – in a horse and carriage!  When people started assembling on the New York docks in 1913 to hear reports of the missing Titanic, half of them arrived in horses and carriages.

We eventually made the energy transformation to the “horseless carriage” of automobiles but it wasn’t easy. People were afraid of the new invention.  They didn’t know how to work it. They fretted over the extraordinary speeds that could be reached – 30 miles an hour!  They did not like the nasty exhausts that some new technologies produced.

Nor was it ever certain which means of propulsion for the new “automobiles” would prevail. There were three contenders – the electric car, the steam car and the internal combustion engine running on any number of fuels.  Gasoline was not the foremost possibility. When Henry Ford built his first model in 1895, called the “quadricycle,” he designed it to run on corn ethanol, which seemed like a reasonable alternative.

The steam car set speed records of 200 miles per hour and the electric showed great promise as a gadabout town car. But the internal combustion eventually prevailed. Why?  The steam car, running on coal, took too long to warm up – about 20 minutes.  The electric car had a very short range, as it still does today. The internal combustion engine was awkward because it required the driver to hand-crank the engine from the front.  There was also a question of whether there would be enough fuel available to run large numbers of cars.  At the time, oil was still a relatively rare commodity, marketed mainly for the “lamps of China.”  But when Spindletop gushed forth in 1901, questions about the oil supply faded.  And when Charles Kettering invented the electric starter in 1912, the battle was over.

Still, Henry Ford didn’t particularly like gasoline and never gave up on the idea that ethanol was a better alternative.  Gasoline had a lower octane rating, was much more toxic (particularly when blended with tetra-ethyl lead to raise its octane rating) and emitted more pollutants. It was also more explosive and required complex refining, whereas ethanol was relatively easy to produce. Ford had roots in farm country and as late as 1925, with the farm belt in a chronic recession, he argued that farmers should be growing their own fuel. “The fuel of the future is going to come from fruit like that sumac out by the road, or from apples, weeds, sawdust — almost anything,” he told The New York Times. “There is fuel in every bit of vegetable matter that can be fermented. There’s enough alcohol in one year’s yield of an acre of potatoes to drive the machinery necessary to cultivate the fields for a hundred years.”

These ideas still resonate today.  Making auto fuel from crops has become a reality since we add 10 percent corn ethanol to our gasoline supplies, cutting our dependence on foreign oil.  There is still talk about using the much larger portions of “crop wastes” to produce cellulosic ethanol, although the technology to do this economically has not emerged yet.  Electric cars are getting another run as battery life and range are extended.  And there is a range of other alternatives – compressed natural gas (CNG), liquefied natural gas (LNG), hydrogen fuel cells and methanol derived from natural gas, coal or any number of organic sources, including garbage, crops and crop wastes.  We have a regular Thanksgiving feast of options before us.  It’s just a question of finding out what works best.

So remember, no technology is forever.  The holiday revelers sleighing toward grandmother’s house for Thanksgiving never dreamed they might one day be making the same trip across 300 miles of countryside at speeds of 60 miles an hour. And today when you’re speeding down the Interstate in a car powered by gasoline from Saudi Arabia, you may not dream that in ten years you could be driving a car running on switchgrass grown on the scrubland of South Dakota or natural gas pumped from the Marcellus in Pennsylvania.  Yet stranger things have happened.  You never know where that path over the river and through the woods is going to lead.

Robert Rapier loves methanol

/in , /by

Robert Rapier – “R2” as he calls himself in good scientific notation – is one of the smartest people out there when it comes to energy. A master’s graduate in chemical engineering from Texas A&M University, Rapier is chief technology officer and executive vice president for Merica International, a renewable energy company. He also writes a regular column at EnergyTrendsInsider.com.

And he is a big enthusiast of methanol.

In a series of recent columns, Rapier has made a strong case that methanol is our best option for replacing foreign oil. He believes it can be done cleanly and in a way that also reduces carbon emissions. Unfortunately, one of the biggest impediments, according to Rapier, is the huge political momentum behind corn ethanol, which he regards as an inferior fuel. He is also highly critical of the biofuels effort, which has attracted so much attention in the form of venture capital from Silicon Valley.

“You can buy methanol today for around $1 per gallon,” he said. “This is a big, well-established business that does not receive heavy subsidies and government support as ethanol does. On a per BTU basis, unsubsidized methanol costs $17.61 per million BTUs. You can buy ethanol today – ethanol that has received billions in taxpayer subsidies – for $1.60 per gallon. On a per BTU basis, heavily subsidized and mandated ethanol sells for $21.03 per million BTUs.”

Yes, you read that correctly. We are paying 20% more for ethanol, enabled via highly paid lobbyists, heavy government intervention, taxpayer funds and protectionist tariffs than we are for methanol that has long been produced subsidy-free.

Unfortunately, the decision to mandate ethanol consumption while ignoring methanol has been based much more on politics than on the two fuels comparative advantages. “The fact is, methanol simply has not had the same sort of political favoritism, but is in [Rapier’s] opinion a far superior option to ethanol as a viable, long-term energy option for the world.”

Where biofuels are concerned, Rapier states that the effort has always been predicated on the assumption that we will eventually switch from corn ethanol to much more abundant, non-food cellulosic feedstocks such as switch grass. We just have to wait until somebody comes up with a way to break down cellulose. What investors do not seem to realize is that techniques for breaking down cellulose have been around since the 19th century. They just have proved to be too expensive.

But “high costs have never been a deterrent for Silicon Valley entrepreneurs who wielded Moore’s Law as the solution to every problem. In their minds, the advanced biofuel industry would mimic the process by which computer chips continually became faster and cheaper over time. But advanced biofuels amounted to a fundamentally different industrial process that was already over 100 years old. A decade into this experiment it is clear that Moore’s Law isn’t solving the cost problem.”

(Actually, if you read George Gilder’s latest book, “Knowledge and Power,” you would realize that mathematicians such as Claude Elwood Shannon and John von Neumann have determined that information as an entirely separate entity from energy and matter. Moore’s Law applies only to information, not matter and energy.)

Rapier says biofuels will never succeed until the effort at developing them is redirected into producing methanol rather than ethanol once again:

For methanol, we can produce it from biomass via a similar process to how it is produced for $1 per gallon today. There are numerous biomass gasifiers out there. Some are even portable. They do not require high fossil fuel inputs and they utilize a much larger fraction of the biomass. They aren’t limited to cellulose. They gasify everything – cellulose, hemicellulose, lignin, sugars and proteins – all organic components. And if there is also a heating application, the combined heat and fuel or power efficiency of a biomass to methanol via gasification route is going to put cellulosic ethanol to shame. In any case, the efficiency of biomass gasification to methanol is going to put cellulosic ethanol to shame, because it doesn’t have to deal with all of that water present in the ethanol process.

Altogether, Rapier argues that methanol has a much broader potential feedstock, is easier and cheaper to produce and could be manufactured in much larger quantities than corn ethanol. And this doesn’t even consider the possibility of synthesizing it from our superabundant supplies of natural gas. The problem is that “methanol doesn’t have a big lobby and 42 senators from farm states it can count on for perpetual support.”

At Fuel Freedom Foundation, we believe we should pursue all these options – ethanol, biofuels, compressed natural gas (CNG), liquefied natural gas (LNG) and electric cars. They all offer the possibility of reducing the $350 billion we shell out each year for imported oil. But we can’t help but admire Rapier’s observation that the methanol option is greatly underappreciated. The reasons are: 1) the EPA restrictions that make it illegal to use in car engines and 2) the lack of any large constituency such as the farm lobby that stands to gain from it. For that reason alone we’re very encouraged by Rapier’s writings and look forward to more in the future.
