Is butanol the next big thing in biofuels?

/in , /by

Fuel Freedom recently learned about a man named David Ramey who drove his 1992 Buick Park Avenue from Blacklick, Ohio to San Diego using 100 percent butanol, without making any adjustments to his engine.

Ordinarily this wouldn’t be big news. But with the EPA now considering cutbacks in the 2014 biofuels mandate, some producers of ethanol are starting to turn to butanol as a way of getting around the limitations of the 10 percent “blend wall” that is threatening to limit ethanol consumption. This could be another breakthrough in our efforts to limit foreign oil.

Butanol is the alcohol form of butane gas, which has four carbons. Because it has a longer hydrocarbon chain, butane is fairly non-polar and more similar to gasoline than either methanol or ethanol. The fuel has been demonstrated to work in gasoline engines without any modification to the fuel chain or software.

Since the 1950s, most butanol in the United States has been manufactured from fossil fuels. But butanol can also be produced by fermentation, and that’s where another opportunity for reducing our dependence on fossil fuels exists.

The key is a bacterial strain called Clostridium acetobutylicum, also named the Weizmann organism for pioneering biological researcher Chaim Weizmann, who first used it to produce acetone from starch in 1916. The main use for the acetone was producing Cordite for gunpowder, but the butanol, a byproduct, eventually became more important.

Once set loose on almost any substratum, Clostridium acetobutylicum will produce significant amounts of butanol. Anything used to produce ethanol — sugar beets, sugar cane, corn grain, wheat and cassava, plus non-food crops such as switchgrass and guayule and even agricultural byproducts such as bagasse, straw and corn stalks — can all be turned into butanol. (Of course, not all of these are economical yet.)

Given the modern-day techniques of genetic engineering, researchers are now hard at work trying to improve the biological process. In 2011, scientists at Tulane University announced they had discovered a new strain of Clostridium that can convert almost any form of cellulose into butanol and is the only known bacterium that can do it in the presence of oxygen. They discovered this new bacterium in, of all places, the fecal matter of the plains zebra in the New Orleans Zoo.

DuPont and BP are planning to make butanol the first product of their joint effort to develop next-generation biofuels. In Europe, the Swiss company Butalco is developing genetically modified yeasts from the production of biobutanol from cellulosic material. Gourmet Butanol, a U.S. company, is developing a process that utilizes fungi for the same purpose. Almost every month, plans for a new butanol production plant are announced somewhere in the world. Many refineries that formerly produced bioethanol are now being retrofitted to produce biobutanol instead. DuPont says the conversion is very easy.

What are the possible drawbacks? Well, to match the combustion characteristics of gasoline, butanol will require slight fuel-flow increases, although not as great as those required for ethanol and methanol. Butanol also may not be compatible with some fuel system components. It can also create slight gas-gauge misreadings.

While ethanol and methanol have lower energy density than butanol, both have a higher octane rating. This means butanol would not be able to function as an octane-boosting additive, as ethanol and methanol are now doing. There have been proposals; however, the proposals are for a fuel that is 85 percent ethanol and 15 percent butanol (E85B), which eliminate the fossil fuels from ethanol mixes altogether.

The only other objection that has been raised is that consumers may object to butanol’s banana-like smell. Other than that, the only problem is cost. Production of butanol from a given substratum of organic material is slightly lower than ethanol, although the increased energy content more than makes up for the difference.

Ironically, the EPA’s decision to cut back on the biofuels mandate for 2014 is now driving some refiners to convert to butanol, since its greater energy density will help it overcome the 10 percent “blend wall.”

“Michael McAdams, president of the Advanced Biofuels Association, an industry group, said butanol was a ‘drop-in’ fuel, able to be used with existing gasoline pipelines and other equipment because it does not have a tendency to take up water, as ethanol does,” The New York Times reported last October. “‘It’s more fungible in the existing infrastructure,’ he said. ‘You could blend it with gasoline and put it in a pipeline — no problem.’

“Butanol would also help producers get around the so-called blend wall, Mr. McAdams said…With the 10 percent limitation, ‘you don’t have enough gasoline to put the ethanol in,’ he said. ‘You don’t have that problem with butanol.’”

So here’s to butanol. It will be yet another big step in reducing our dependence in foreign fuels.

Of myths, oil companies and a competitive fuel market

/in , /by

I do not wish to join the intense dialogue concerning whether or not the government should allow exports of crude oil. Others are already doing a good job of confusing and obscuring the pros and cons of selling increased amounts of America’s growing oil resources overseas.

What I do want to do is just focus on the logic of one of the oil industry’s major arguments for extending the permitting of exports — again, not on the wisdom of exporting policy. Permit me to do so in the context of the industry’s long-standing argument concerning the pricing of gasoline to U.S. consumers. The argument is that more oil drilling in the U.S. will lower the price of gas and put America on the path to oil “independence.”

In somewhat of circuitous manner, oil companies are using the opposite of their domestic advocacy for “drill, baby, drill” policy as a way to keep prices lower at the pump. Their yin is that producing more oil in the U.S. and sending significant amounts overseas, combined with declining vehicular fuel demand, will lower gas prices. Economist Adam Smith would applaud the simplicity if he were alive and well. Their yang presents a bit more complicated set of “ifs.” That is, the industry presumes that fulfillment of the yen (excuse another pun) to export will result in more U.S. oil being drilled because of increased world demand generated by the assumed ability of the U.S. to produce oil at less costs than the world price for oil. It will also help foster infrastructure development in the U.S. to break up current log jams concerning oil transportation. Finally, it will facilitate more efficient refineries, allowing them to specialize in different types of oil. The yin and yang will result in (marginally) lower prices of gasoline — so goes the rhetoric and oil-industry-paid-for studies.

Paraphrasing Dr. Pangloss in “Candide,” the oil companies hope for the “best of all possible worlds.” But, before Americans run out and buy stock, note the price of gasoline does not directly reflect oil production volume. Indeed, gas prices, despite increased supplies, have gyrated significantly and now hover nationally over $4 a gallon. Generally, oil and gas prices relate to international prices, tension in the Middle East and investor and banker speculation — not always or directly domestic costs. Stockholders and executives of oil companies function not on patriotism but on profit and to the extent that the law permits, they will sell overseas to get the best price — in effect, the best dollar over payment for a barrel of oil. Consumers, I suspect, are rarely a significant part of their opportunity costing.

Unfortunately, lack of strong empirical evidence tempers the company’s argument that increased world demand will stimulate good things like refinery efficiency and log-jam-ending infrastructure. Maybe if the price per barrel is right (clearly, higher than it is now) and seems predictable for more than a small period of time, refinery and infrastructure developments will be positive. But, the costs to the consumer, in this context, will be higher. It will also be higher because shale oil is tight oil and more risky and costly to drill.

Oil independence is a myth suggested by oil industry and a non-analytical media. Certainly, the oil boom and less vehicular demand have generated less imports and less dependency. But we still buy nearly 300 billion dollars’ worth of oil every year to respond to need and we still produce far less than demand.

Somewhere in the dark labyrinth of each major oil company is a pumped-up (another pun), never-used, secret justification for franchise agreements impeding the sale of alternative fuels in their retail outlets. To alleviate guilt, it may go something like this: “Monopolies at the pump will allow us to make larger profits. You know we will someday soon want to give back some of the profits to consumers by lowering the price of gasoline.” If you believe this still-secret beneficence, let me sell you the Brooklyn Bridge.

There is another way to steady the gasoline market and lower consumer costs. Inexpensive conversions to allow older vehicles to use safe, cheaper and environmentally better alternative fuels (as opposed to gasoline), combined with expanded use by flex-fuel owners of alternative fuels, would add competition to the fuel market and likely reduce prices for consumers. Natural-gas-based ethanol is on the horizon and methanol, once the EPA approves, will follow, hopefully shortly thereafter. Electric cars, once costs are lower and distance on single charges is higher, will be a welcome addition to the competitive mix.

The Battle Over Ethanol Takes Shape

/in , /by

The decision isn’t scheduled until June but already opposing sides are converging on Washington, trying to pressure the Environmental Protection Agency over the 2014 Renewable Fuel Standard for ethanol.

Last week almost 100 members of the American Coalition for Ethanol descended on the nation’s capital for its annual “Biofuels Beltway March,” buttonholing 170 lawmakers and staffers from 45 states.  The object was to send a message to EPA Administrators Gina McCarthy to up the ante on how many billions of gallons the oil refining industry will be required to purchase this year.

The ethanol program is currently in turmoil.  The latest problem is rail bottlenecks that have slowed shipments and created supply shortages over the winter months.  Record-breaking cold and four-foot snow pack have been partly responsible but the rail lines are also becoming overcrowded.  With all that oil gushing down from the Bakken and Canadian crude now finding its way into tank cars as the Obama Administration postpones its decision over the Keystone Pipeline, ethanol is getting tangled in traffic.  .

“Ethanol for April delivery sold for about $3.02 a gallon on the Chico Board of Trade, an 81 percent increase over the low price during the past 12 months of $1.67 a gallon reached in November,” reported the Omaha World-Herald last Friday  “This weeks settlement price of $2.98 a gallon was the highest since July 2011.”  With only so much storage capacity, some ethanol refineries have been forced to shut down until the next train arrives to carry off the inventory.  As ethanol becomes mainstream, it is becoming more and more subject to market events beyond its control.

But the big decision will be EPA’s ruling in June.  In accord with the 2008 Renewable Fuel Act, Administrator McCarthy must set a “floor” for amount of ethanol refiners will have to incorporate into their blends during 2014.  The program ran into trouble last year when the 13.8 billion gallon requirement pushed ethanol beyond the 10 percent “blend wall” where the auto companies will not honor warrantees in older cars.  Refiners were forced to purchase compensating Renewable Identification Numbers (RINs), which exploded in value from pennies to $1.30 per gallon, forcing up the price of gasoline.  Contrary to expectations, gasoline consumption has actually declined over the last six years, from 142 billion gallons in 2008 to 134 billion in 2013 as a result of mileage improvements plus the lingering effects of the recession.  Last November McCarthy proposed reducing the 2014 from 14.4 billion gallons to 13 billion.  The industry has been crying “foul” ever since.

But there are other ways to fight back.  Last week in Crookson, gas stations were offering Minnesota drivers 85 cents off a gallon for filling up with E-85, the blend of 85 percent ethanol that many see as the real solution to the blend-wall problem.  “We want the public to understand there are different ratios of gasoline and ethanol and how they can save you money,” Greg LeBlac, of the Polk County Corn Growers, told the Fargo Valley News. 

At the annual meeting of the American Fuel and Petroleum Manufacturers (APFM) in Orlando last week, Anna Temple, product manager at WoodMac, made the case that the industry should forego efforts to raise the blend wall from 10 to 15 percent and instead shoot for the moon, leapfrogging all the way to E-85, where ethanol essentially replaces gasoline completely.  (The 15 percent only ensures starts in cold weather.)

“E-15 is a non-starter in terms of market share,” Temple told her audience, as reported by John Kingston’s in Platts.  http://blogs.platts.com/2014/03/25/eight-fillups/  She argued the incremental battle would absorb vast amounts of political capital yet still not be enough to absorb the 15-billion-gallon target for 2021.  Instead, Temple pointed to the growing fleet of flex-fuel vehicles that now numbers around 15 million, headed for 25 million in 2021 or 10 percent of the nation’s 250-million-car fleet.

“If U.S. drivers poured about 200,000 barrels-per-day of E-85 into their flex fuel cars in 2021, that would take care of about 17 percent of the scheduled ethanol mandate,” Temple said.  “It would only require that flex-fuel owners fill a 15-gallon tank eight times a year.”   The remainder would be absorbed in the 10 percent blend and ethanol producers would not have to cut output.

Platts’ Kingston checked the math and found that even this goal would leave ethanol consumption slightly above the blend wall at 10.5 percent.  “Still, the very modest number of eight fill-ups per flex fuel vehicles per year makes the whole blend wall issue seems a lot less daunting,” he confessed.

Of the 15 million people who own flex-fuel vehicles, of course, many don’t even realize it.  (The yellow gas cap or a rear-end decal are the giveaway.)  But the number of gas stations offering E-85 pumps is rising.  The Energy Information Administration now estimates the number at 2,500 with most of the growth taking place outside the Midwestern homeland.  California and New York each have more than 80 stations apiece.

The problem of rail bottlenecks can probably be solved by increasing the number of E-85 outlets and flex-fuel vehicles to bring supplies closer to the place of consumption.  Still, the industry would probably be happy to have a bigger renewable fuel mandate as well.

Progress on Fuel Efficiency: More is needed

/in , /by

Every now and then I will read a White House Blog.  They’re sort of a fun read when you’re depressed about the state of the world and the country.  The content always somehow reminds me of  Gene Kelly dancing in the street in the middle of the rain, or that old (possibly New Yorker) cartoon where the patient tells the psychiatrist that he is not doing well and the good doctor says ‘no you’re just fine, you’re happy and healthy.’  Probably neither is the proper analog to the politically necessary positive nature of the White House blurbs.  I marvel at times at the President’s ability to seek a better America, especially given the politics of the present.  While his optimism and tenacity don’t always come through as “Morning in America,” I believe that his attitude is based on a reasonable outlook about what the nation can do, if it can engage in an honest dialogue about key environmental and alternative fuel issues.

Last week’s blog focused on the White House’s effort to increase fuel efficiency standards.  It notes correctly that the President’s legislative approach to the environment has resulted in the toughest fuel economy standards in history:

“Under the first ever national program, average fuel efficiency for cars and trucks will nearly  double, reaching an average performance equivalent to about 54.5 miles per gallon by 2025….In 2011, the President also established the first-ever fuel efficiency and greenhouse gas standards for medium and heavy duty vehicles, covering model years 2014 through 2018.”

More is to come! Increased fuel efficiency standards are currently being addressed by the Administration, and the EPA is hard at work developing Tier 3 rules.

The Administration’s record is a decent one and has benefited the environment, lessened ghg emissions, and strengthened the economy. Regrettably though, fuel efficiency regulations primarily apply to new cars.  They should be matched by a cost efficient and comprehensive federal effort to encourage the conversion of older non flex fuel vehicles; they also should encourage Detroit to continue producing larger numbers of flex fuel cars.

In this context, EPA and Detroit automakers need to reach a consensus concerning effective engine recalibration alternatives, as well as an extension of consumer warranties and related financial coverage of recalibrated vehicles.  Without permitting older cars to achieve the fuel efficiency and environmental advantages of flex fuel vehicles, we will not be able to respond to Pogo’s admonition and Commodore Oliver Perry’s initial statement (paraphrased): that we, as a nation, have met the enemy, and he is us!

To grant primacy to new or relatively new flex fuel cars would increase the nation’s ability to reduce ghg emissions and other environmental pollutants (e.g. NOx and SOx). There are well over 200,000,000 non flex fuel cars in the U.S. that cannot readily use available fuel blends higher than E-15 and will not be able to use natural gas based ethanol that hopefully relatively soon will come on the market.

Lowering the certification costs of conversion kits by the EPA and increasing the number of manufacturers of those kits would bring down their price from around 1,000 dollars to the near 300 dollar level that is common in the “underground” market.  Simplifying legal conversion could  —and indeed would —-make an important environmental difference.  Such action would also open up the fuel market to competition, and likely lower the price of gas at the pump for consumers. Finally, such actions would also support the President’s objective to wean the nation off of oil and gasoline.  Oh Happy Day!  Go for it Gene Kelly and the American Association of Psychiatrists!  It might be time to show some real love for environmentally and efficiency neglected and needy older vehicles.

Can Butanol Be the New Ethanol?

/in , /by

Even as the ethanol industry is wobbling over the Environmental Protection Agency’s decision to cut back on the ethanol mandate in 2014, a new candidate has emerged as an additive to gasoline – butanol.

Virgin Airways founder and CEO Richard Branson has announced that his Virgin Green Fund will be cosponsoring a groundbreaking butanol manufacturing plant in Luverne, Minnesota.  “Butanol is the future of renewable fuel,” said Branson, who is already using renewable jet fuel for his airline.  “It’s hugely versatile and can be used to produce gasoline fuel blends, rubbers, solvents, and plastics, which gives us scope to enter a range of markets,” he said in an interview with Bloomberg.

Corn ethanol now dominates the $26 billion gasoline additive market, drawing the glucose content out of 45 percent of the nation’s corn crop (the protein is fed to animals).  Branson’s butanol would use a similar feedstock – corn, sugar cane or cellulosic biomass – but would produce a fuel that has 84 percent of gasoline’s fuel density compared to ethanol’s 66 percent, although ethanol has a higher octane rating.  The implication is that butanol could be mixed at higher blends, giving it almost the same range as gasoline.

Both butanol and ethanol are made through a process that employs yeasts to ferments the glucose from organic material into alcohols.  Methanol, the simplest alcohol, has one carbon joined to a hydroxyl ion while ethanol has two carbons and butanol has four.  Octane, the principal ingredient in gasoline, has eight carbons without the hydroxyl ion.

As far a butanol is concerned, it’s not as if people haven’t tried this before.  Both BP and Royals Dutch Shell have experimented with producing butanol from organic material but have found the process harder than they anticipated.  “There is certainly a potential, but there have been quite considerable problems with the technology,” Clare Wenner, of the London-based Renewable Energy Association, told Bloomberg.  “It’s taking a lot longer than anybody thought years ago.”

Gevo’s plant in Minnesota, for instance, has been running at only two-thirds of its 18 million gallon-a-year capacity because of a contamination in its yeast fermenting facility in September 2012.  Similar instabilities in the microbial-based process have dogged the efforts to break down cellulose into simple molecules.  There operations can often be performed in the laboratory but become much more difficult when moved up to a commercial scale.

Branson is confident these obstacles can be overcome.  He’s already got Silicon Valley investor Vinod Khosla on board in Gevo and Total, the French oil company, has also taken a stake.  Together they have enlisted big ethanol producers such as Big River Resources and Siouxland Ethanol to commit to switching their manufacturing process to butanol.  Butamax Advanced Biofuel, another Minnesota refiner funded by Dupont and BP, is also in the process of retrofitting its ethanol plant to butanol.  Taken together, these facilities would be able replace 1 billion of the 14 billion gallons of ethanol now being produced every year.

Whether this would be enough to make a bigger dent in America’s oil import budget remains to be seen.  The 14 billion gallons of ethanol currently substitutes for 10 percent of our gasoline and about 6 percent of our total oil consumption.  The Environmental Protection Agency has limited ethanol additives to 15 percent of the blend, mainly to protect older cars.  (In Iowa, newer cars are running on an 85 percent blend.)  Now the reduction in the 2014 mandate is making the ethanol industry nervous about overcapacity.  Butanol is less corrosive of engines and the 16 percent blend could give it an edge.

On another front, T. Boone Pickens’ Clean Energy Fuels announced this week that it may turn a profit for the first time since its founding in 1997.  Clean Fuels is concentrating on supplying compressed natural gas for trucks, signing major contracts with Frito-Lay, Proctor & Gamble, United Parcel Service and Ryder.  It is also attempting to set up a series of filling stations on the Interstate Highway System.  The use of CNG requires an entirely new infrastructure, however, rather than the easy substitution of liquid and butanol.

The dark horse here is methanol, which is liquid and fits easily into our present infrastructure but would be synthesized from natural gas.  Somehow, methanol has not attracted the attention of Branson’s biofuels and Pickens’ CNG.     All of these efforts hold promise, however, and would make a huge dent in our annual $350 billion bill for oil imports, which constitutes the bulk of our $450 billion trade deficit.  So good luck to all and may the best fuel win – or all of them, for that matter.

There’s Gold in Them Thar’ Flares

/in , /by

Walter Breidenstein may be the only CEO in America who still answers the company phone himself. If his operation is still something of a shoestring, it’s because he’s spent four years trying to duel with perhaps the most formidable foe in the country, the oil companies.

“I’ve been trying to get into North Dakota for four years to show them there’s a way to make money by stopping flaring,” says the 48-year-old who started his entrepreneurial career at 15 by washing dishes. “The oil companies have done everything they can to keep me out of the state and the bureaucracy has pretty much goes along with them. The companies know that as soon as they acknowledge we’ve got a workable system here, they’d have to buy one of our rigs for every well in the state.”

North Dakota, in case you haven’t heard, has become one of the biggest wasters of natural gas in the world by flaring off $1 billion worth a year while producing carbon emissions equal to 1million automobiles.  But oil is what the drillers are after and, as it was in the early days of the oil industry; gas is regarded pretty much as a nuisance. The result is gas flares that make the whole state look like neighboring Minneapolis from outer space.

The flaring has generated a lot of negative publicity, environmentalists are up in arms and landowners have sued over lost royalties. The big guys are starting to move into the state. The New York Times ran an article this week about new pipeline construction, fertilizer factories and GE’s “CNG in a Box,” which will capture flared gas and sell it asnatural gas.

Breidenstein has a different idea.  “Somewhere around 2000 I started reading about methanol technology and realized it was a very undervalued resource,” he says. “Then I read George Olah’s The Methanol Economy in 2006 and that convinced me.  At Gas Technologies we’ve been trying to put Olah’s vision into practice.”

Gas Technologies has developed a $1.5 million portable unit that captures flared gas and converts it to methanol. “It’s a very accessible device,” says Breidenstein.  “You can move it around on a flatbed truck.”  The company ran a successful demonstration of a smaller unit at a Michigan oil well last fall but still hasn’t been able to break into North Dakota.

“The oil companies’ attitude is that money is no problem as long as they don’t have to spend it,” says Breidenstein.  “I’ve been in the business 25 years and I know where they’re coming from. But the problem is no one is forcing them to deal with flaring. And as long as they can keep throwing that stuff into the atmosphere for free, nobody’s going to look for a solution.”

You’d think with a billion dollars worth of natural gas being burning off into the atmosphere each year, though, there’d be some say to make money off it and that’s what frustrates Breidenstein.

“Our rig costs between $1 and $2 million dollars,” he says.  “But by capturing all the products of flared gas, you can make around $3500 per day.  That puts your payback at around three to four years.  But the oil companies don’t think that way. They won’t look at anything that goes out more than six months.

That puts things in the hands of state regulators and so far they have sided with the oil companies. “By statute, the oil companies are allowed to flare for a year it there’s no solution that’s economical,” says Alison Ritter, public information officer for the North Dakota Department of Mineral Resources.  “There’s nothing we can do to require them to buy from one of these boutique firms. Many oil companies have already committed their gas to pipeline companies and they can’t back out of those contracts.”  Still, the pipelines may not be built for years. “You have to understand, the Bakken Oil Field is 15,000 square miles, the size of West Virginia,” adds Ritter.  “It’s hard to service it all with infrastructure. We’re building pipelines as fast as we can.” Of 40 applications for flaring exemptions submitted this year the state has approved two and denied one, with the other 37 pending.  While they are pending, flaring goes on.

Of course if Gas Technologies were to start receiving orders right now, they’d be hard pressed to produce a half-dozen of them let alone the 500 that the state might require. “We’ve had talks with venture capitalists but if you’re not from Silicon Valley, they’re not interested,” says Breidenstein.  “But we’ve got a business model here and we know it can work.”

At least someone has taken notice. This year Crain’s Detroit Business rated Gas Technologies Number One in the state for innovative technology, ahead of 99 other contenders, including General Motors, Ford, Volkswagen, Whirlpool, Dow Chemical and the University of Michigan.  “Because the Walloon Lake company’s patents are potential game-changers, its patents rank high on the value meter with a score of 156.57 (anything over 100 is considered good),” said the editors.

It may not be long before others start noticing as well.

Are Hydrogen Cars the Future – Again?

/in , /by

The hydrogen car may be on the road to another comeback – again.  At the annual auto show in Los Angeles last week, both Honda and Hyundai unveiled “concept cars” of hydrogen models they expect to be available by 2015.  As a result, the automobile press has been filled with stories its revived prospects.

“For a long time, hydrogen fuel-cell vehicles were seen as a tantalizing technology to help reduce society’s reliance on oil,” Brad Plumer wrote in the Washington Post. “But the vehicles themselves were seen as forbiddingly expensive. Not the pendulum may be swinging back.”

“Toyota made a decagon – the fuel-cell car is going to be a big part of our future,” wrote Bradley Berman in The New York Times, quoting Toyota spokesman John Hanson.  “Today Toyota is not alone,” he continued. “Four other carmakers – General Motors, Hyundai, Honda and Mercedes-Benz – are also promising fuel-cell cars in the next few years.”

The prospect of an automobile running on hydrogen is indeed perpetually attractive.  Hydrogen is the most common element in the universe.  When combined with free oxygen in the atmosphere it “combusts” to produce H2O – water.  There are no other “exhausts”. Thus hydrogen promises transportation absolutely clean of any air pollution.  No global warming, either.

But it isn’t quite that simple.  The question that always presents itself is, “Where do you get the hydrogen?” Although hydrogen may be the most common element on earth, all of it is tied up in chemical compounds, mostly methane and water.  Accessing this hydrogen means freeing it up, which requires energy.

Most of our commercial hydrogen is made by “reforming” natural gas, which splits the carbon and hydrogen in methane to produce carbon dioxide and free hydrogen. That doesn’t help much with global warming.  Another method is to split water through electrolysis. That is a much cleaner process but requires a considerable amount of electricity. Depending on what power source is used, this can produce zero or ample emissions. If it’s coal, the problem is made much worse. If it’s clean sources such as solar or nuclear, then there can be a strong advantage. In the 1930s, John Haldane proposed giant wind and solar farms that would generate hydrogen that could fuel all of society. Such facilities generating hydrogen for transportation would be a step toward such a utopia.

Even then, however, there are problems.  Hydrogen is the smallest molecule and leaks out of everything.  It is very difficult to transport.  Joseph Romm, a disciple of alternative energy guru Amory Lovins, was appointed head of hydrogen car development program under President Bill Clinton and worked for two years on its development.  In the end, he became very disillusioned and wrote a book entitled The Hype About Hydrogen, in which he argued that the idea really wasn’t practical. Romm is now one of the country’s premier global warming alarmists on ClimateProgress.org.

What has apparently brought hyfrohgen cars back to the forefront has been the substitution for platinum as the principal catalyst in the fuel cell process.

A fuel cell produces an electric current by stripping the electron off a hydrogen atom and running it around a barrier that is otherwise permeable to a naked proton.  The proton and electron are reunited on the other side of the barrier, where they combine with free oxygen to form water.  Until recently, platinum was the only substance that could fill this barrier function. This made fuel cells very expensive and raised the question of whether there was enough platinum in the world to manufacture fuel cells in mass production.  But several platinum substitutes have now been found, making fuel cells considerably cheaper and more accessible.

Estimates are now that next year’s Hyundai and Honda FCVs will sell for about $34,000, which puts them in the range of electric vehicles such as the Nissan Leaf and the Toyota Prius.  (The Tesla, a luxury car, is  priced in a much higher range,)  The problem then becomes fueling.  The FCV offers considerable advantages over the EV in that it has a range of 300 miles, comparing favorable to gasoline vehicles.  It can also be refilled in a matter of minutes, like gasoline cars, whereas recharging  an EVs can take anywhere from  20 minutes to three hours. But hydrogen refueling stations have not materialized, despite former governor Arnold Schwarzenegger’s promise of a “hydrogen highway.” At last count there were 1,350 EV recharging stations around the country but only ten hydrogen stations, eight of them In Southern California.

All this suggests that neither hydrogen cars or electric vehicles will be sweeping the country any time soon.  Neither the Chevy Volt nor the Nissan Leaf have sold well and are not expected to do much better next year.  If you read the press stories carefully, you soon realize that the reason the automakers are constantly cycling back and forth between electric and hydrogen cars is that they are trying to meet California’s requirements for low-emissions vehicles that will allow them to continue selling in the state. The problem, as always, is consumer resistance..  The automakers can manufacture all the hydrogen and electric cars they want but consumers are not always going to buy them, especially at their elevated price.  So the manufacturers will end up dumping them on car rental agencies where they will sit on the back lots, as did the first generation of EVs.

There is, however, one type of alternative that succeeded handsomely in California and had widespread consumer acceptance, although it is completely forgotten today.  That is methanol.  In 2003, California had 15,000 cars running on blends of up to 85 percent methanol.  Consumers were extremely happy and did not have to be dragooned into buying them.  Refueling was easy since liquid methanol slots right into our current gas stations. Cars that run on methanol can be manufactured for the same price as cars that run on gasoline.

The experiment only ended because natural gas, the main feedstock for methanol, had become too expensive.  In 2003, natural gas was selling as high as $11 per mBTU, making it more expensive than gasoline.  That was before the fracking revolution.  Today natural gas sells for less than $4 per mBTU and the industry is coping with a glut.  Methanol, which is already produced in industrial quantities, could sell for $1 less than motorists are now paying for energy equivalent in gasoline.  Moreover, methanol can be made from garbage and crop wastes and a variety of other sources that would reduce it’s carbon footprint.

Hydrogen and electric cars each have a future and it is good to see the auto companies keep experimenting with them.  But each has impediments that are going to be difficult to overcome. Methanol, on the other hand, is a technology that could be implemented today at a price that not require subsidies.  Even if it is only perceived as a “bridge” to some more favorable, low-carbon future, it is worth pursuing now.

What Do Iceland and Israel Have in Common?

/in , /by

In New York City politics they used to talk about the “three I’s” – the Irish, the Italians and the Israelis, which formed the major voting blocs. Today we can talk about the “two I’s” –two countries that are making significant progress in methanol as an alternative fuel – Iceland and Israel.

Iceland is by far the leader.  The Icelanders are blessed with a string of volcanoes that bristle with geothermal energy. Tapping these vents, they are able to get 25 percent of their electricity from this natural, renewable source – the highest proportion of geothermal in the world. Drawing the other 75 percent from the island’s ample hydroelectric resources, you have a grid running entirely without fossil fuels.

But that’s just the beginning. Blessed with this amplitude of natural resources, the Icelanders have decided to turn it into an auto fuel as well. In 2011 a Reykjavik-based company called Carbon Recycling International set up a unique operation that will capture the small amounts of carbon dioxide and carbon monoxide emitted from geothermal vents and transforming that into an auto fuel as well.

The target ingredient is methanol, the simplest alcohol, made up of a single carbon, three hydrogens and a hydroxyl ion. Methanol is a liquid at room temperature and can be easily funneled into our existing gas-station infrastructure. Methanol burns with about 50 percent of the energy content of gasoline but has a higher octane rating so the real effect is about 66 percent. Methanol functions similarly to the corn ethanol that currently constitutes 10 percent of our gasoline.

Through a simple procedure, CRI takes the carbon dioxide exhaust from the 75 MW Orka geothermal plant and combines it with hydrogen to produce methanol. The hydrogen is obtained through the electrolysis of water, using electricity from the power plant. The outcome is 5 million gallons of methanol per year. In the United States, the Environmental Protection Agency has not yet approved methanol as a gasoline additive but Iceland allows it to be mixed at a rate of 3 percent (although they also have some Fords running on 50 percent). Cars would actually run on 85 or 100 percent methanol – the Indianapolis 500 cars have done it since the 1960s – but government regulators in both countries are reluctant to give it a try (It would require replacing a few elements in the fuel line to avoid corrosion).

Iceland’s experiment has been so successful that the country has now decided to export the product to Europe. This year CRI has begun to send its “green methanol” to the continent to add to Europe’s gas tanks. The Icelanders advertise that the product adds no additional carbon dioxide to the atmosphere. This is because the carbon dioxide that is captured was already headed for the atmosphere. Instead it is burned in gasoline engines, also ending up in the atmosphere, but along the way it has replaced an equal amount of gasoline that would have produced its own carbon emissions.

Icelanders proclaim they are putting into effect what Nobel Prize Winning chemist George Olah called the “methanol economy.”  In his 2009 book, Beyond Oil and Gas: The Methanol Economy  

Olah and his co-authors outline how methanol from a variety of sources – natural gas, coal and any biological material – could serve as the basis of an economy much less dependent on fossil fuels. At the Orka carbon recycling and geothermal plant, they appear to be doing just that.

At the same time, Olah is finding recognition in Israel as well. This month Olah and his University of Southern California colleague G.K. Surya Prakash became the first recipients of the Eric and Sheila Samson Prime Minister’s Prize for Innovation in Alternative Fuels for Transportation, with Prime Minister Benjamin Netanyahu bestowing the first-ever award. The Israelis are also looking for alternatives to gasoline in order to reach their proclaimed goal of reducing dependence on oil by 60 percent by 2025. With the discovery of new gas supplies in the eastern Mediterranean they are in a good position to apply Olah’s proposed technology in transforming natural gas into methanol for transportation.

Nor is Olah standing still. In an October op-ed contribution to the Wall Street Journal, he announced that he has developed a new technology that will allow large quantities of carbon dioxide from power plants to be transmuted into methanol so that carbon exhausts can be “recycled” just as the they are at Orka. The plan could make use of carbon exhausts in the U.S., perhaps rescuing the fading coal industry.

Iceland and Israel are already taking steps toward the vision of a methanol economy. Will Iowa and Illinois be next?

Ford Leads the Way

/in , /by

The Ford Motor Company stepped front-and-center in the effort to fine alternatives to high-priced imported oil last week with the announcement that it will offer compressed natural gas (CNG) tank as an option in the F-150 pickup truck, its most popular brand that currently sells 700,000 models a year.

Now it won’t come cheap. There’s a $250-$350 charge for the vehicle to come “prepped” from the factory. That means putting hardened valves, valve seats, piston and rings into the V6 engine. But after that, there’s a $7-9000 charge for installing the CNG tank in the cargo bay – made considerably more expensive than in Europe because safety standards are interpreted in a way that makes them much more expensive. This lifts the showroom price from $24,000 to around $32,000. That’s a big chunk but Ford swears you’ll make it back in three years by substituting fuels.

With the price of gas at around $3.80 per gallon and the oil-equivalent of natural gas at around $1.20, those savings should add up fast.  Of course all this assumes that the price differential won’t narrow to its traditional level, but that doesn’t seem very likely now. Electrical plants have shown a tendency to move quickly back to cheaper coal if the price of gas rises, but the difference between the crack spread and the spark spread seems to have separated permanently, much to natural gas’s advantage.

All this is good news for those looking to substitute some of our abundant natural gas for foreign oil in our transport sector.  In fact, there’s a lot of progress being made right now:

Clean Energy Fuels of Newport Beach, CA already has a network of 360 natural gas fueling stations at truck stops along Interstate highways and is trying to build a complete national infrastructure.  NGV stations cost $750,000 a pop but Clean Energy is looking at the long term.  The ready availability of filling stations will help spur the conversion of giant 18-wheel diesel haulers, which most people see as the ripest target for conversion.

Heavy-duty fleet vehicles are making rapid progress.  Buses and garbage trucks are in the forefront. Eight out of ten new vehicles bought in 2012 by Waste Management, the leader in the field, were powered by natural gas.

There are now 120,000 gas vehicles on the road in the United States, according to Natural Gas Vehicles of America, the trade group.  Unfortunately, this constitutes only a tiny fraction of the 15.2 million NGVs worldwide. Iran, Pakistan and Argentina, improbably, are the leaders. We’re behind in making the transition, but there’s plenty of room to catch up.

In a report issued in June, Citi Research estimated that one-quarter of the world’s present consumption of oil could be replaced by natural gas under present conditions. More than 9 million barrels per day could be replaced in truck transport, 2 million of these in the US. Another 3 million b/d could be opted out in marine transport and 200,000 b/d in railroad locomotives.

All this would be fairly easy to transact since it involves large commercial organizations with centralized decision-making.  Sooner or later, however, this approach is likely to run up against limits.  The stumbling block will be the vastly more decentralized system of private automobiles, which still consumes 60 percent of our oil and involves a car in every garage and a gas station on every other corner. Here the problem of building an infrastructure and achieving widespread distribution is much more difficult.

The problem comes because reformers are viewing natural gas as a fuel instead of a feedstock. Compressed natural gas (CNG) and liquefied natural gas (LNG) are the most readily available options – and both are legal – but in the end they are going to have their limits. It will make much more sense to use methane as a feedstock for the manufacture of liquids, methanol in particular.  These will be much easier to transport and will substitute for gasoline in current car engines with only minimum adjustment – nothing like the $8000 required for the F-150. Valero has just opted to build a $700 million methanol manufacturing plant in St. Charles, Louisiana in anticipation of this demand. All depends on whether the Environmental Protection Agency decides to give a go-ahead to use methanol in car engines. The matter is pending.

So the effort to use our abundant natural gas resources to reduce our dependence on expensive, unpredictable and unreliable foreign sources of oil is making headway. Ford’s decision to equip the F-150 with CNG is a beginning. But there’s more to come.

What do Grover Norquist and Edmund Burke have to do with Natural Gas?

/in , /by

I don’t like the idea of advance pledges by candidates concerning how they would vote, if they were elected by us. I believe it is contrary to representative democratic government and denies the fact that economic, security, social and environmental conditions change, often rapidly, and must be responded to with studied intelligence and common sense, not constant polling or focus groups.

I guess I am, at least, part Burkian.  Although it departs from present reality, as the great philosopher and British MP, Edmund Burke indicated, our elected leaders , should use their “…unbiased opinion…mature judgment…enlightened conscience…(our) representative(s) owe …not (their) industry only, but (their) judgment; and (they) betray, instead of serving (us), if they sacrifice ( judgment) to (our often fleeting ) opinion(s).” Voters can, at least in theory if not always in practice, dismiss their representatives at the next election. I am not sure Burke won again after he made his plea for more thinking and less pandering.

I am suffering emotionally (not too significantly) by being tempted by  a Kaplan analogue to Grover Norquist’s “no new taxes” pledge, required of  candidates for office.  While the tax pledge, I believe, is responsible for at least some of the dysfunction in Washington, there is a certain romantic, almost utopian appeal to it with respect to frustrated advocates for more and better fuel choices at the pump than just gasoline. As Emerson wisely indicated, perhaps, “a foolish consistency is the hobgoblin of little minds.”

The new Kaplan analogue to the Norquist pledge would acknowledge that the natural gas train has left the station. Indeed, it has! One has only to look at the number of wells/rigs now in place compared to just a few short years ago and the relatively rapid escalation in gas production.

The natural gas sector has become, and likely will remain, an economic and political powerhouse. In this context, advocates of a “renewable transportation fuel only” approach, risk, implicitly, supporting a short and intermediate term future dependent on oil and gasoline. As a result, their success would likely result in increased environmental degradation, more greenhouse gas (GHG), higher costs for consumers, increased security problems and restricted economic growth. Clearly, the enemy of a short term good would become a distant perfect.

The Kaplan pledge would commit candidates to help secure reasonable and effective federal and state regulations to protect and enhance the environment and significantly reduce GHG production during production, distribution and sales of natural gas-from wellhead to automobile.

The pledge would commit candidates, once elected, to help foster a collaborative public, nonprofit and private sector effort to wean the country off dirty oil and gasoline. It would require them to develop and support initiatives that open up the now almost closed transportation fuel market to safe, environmentally sound, cheaper alternative transition fuels. Finally, it would commit candidates, should they take office, to support the development of renewable fuels and vehicles that would reflect competitive costs and mileage capacity that match the budget and occupation as well as life-style needs of low, moderate and middle income Americans.

I feel sinful in departing from the philosophy of Edmund Burke. I need to contemplate my fall from philosophical grace. I apologize!  I hope I am treated with grace and redemption. My excuse in proposing a Congressional pledge was only a temporary errant fantasy. It “ain’t” going to happen. It is a flight from reality.

But, was it all bad? Perhaps, the Kaplan pledge points the way to an alternative that is not antithetical to Edmund Burke. What if, instead of trying the impossible with elected officials, many  of whom try to fit their views to the, often of the moment, views of their constituents, advocates of a free fuel market and alternative transitional transportation fuels worked to form  a coalition of nonpartisan or bipartisan groups: business, labor, environment, government, academic and community . Each group would join because they are consistent in heart and mind with the Kaplan fuel freedom pledge. Each would accept the intent explicit in the pledge; that is the nation’s need for a comprehensive fuels strategy that would bridge the gap between renewable and natural gas advocates, between environmentalists and the natural gas industry, between liberals and conservatives.

Free market business and conservative adherents would put muscle behind their ideology in seeking a more open fuel market. Liberals would put meaning behind their desire to aid the needy who suffer from the high cost of gasoline and limited job opportunities because budget constraints limit driving. Environmentalists would match their concern for the environment with support for natural gas, ethanol and methanol as transitional fuels — fuels that would reduce GHG and other gasoline generated pollutants. The nation would be better able to secure the stimulus now required to improve economic growth because of the reduced dependency on foreign imports. Every one of us would benefit from success in assuring research and development of renewable fuels. The coalition would inform and increase Congressional understanding of the need for an integrated coherent national fuel strategy. The payoff to elected leaders:  The Coalition would promise to help voters comprehend the nation’s need for alternative fuels and a comprehensive fuel freedom strategy. It would meet with measured success. Sign me up! The best of all possible worlds! Oh Happy Day!  I can dream can’t I?
