Some automakers are going beyond just letting you choose the color of your car, if you actually need an infotainment system, and whether or not you want seat-warmers (yes, duh). They’re letting you choose the fuel that it runs.
That’s all about to change — and no, we’re not advocating anyone getting behind the wheel of a car after drinking (seriously, don’t do that).
There are more than 210 million licensed drivers in the United States, and I’ll venture a guess that the vast majority of them fill their tanks with the old standby, 87 octane unleaded gasoline. Read more →
Picture this.
You’re driving down the road and you notice your tank is almost empty — time to fill up. Read more →
The price of gas rises and falls in cycles, but buyers of the Ford F-150, the best-selling vehicle in the United States the past three decades, have consistently had one complaint: the poor fuel economy of the truck.
Ford Motor Co. CEO Mark Fields thinks the company has solved that problem with the 2015 model F-150 now rolling off the assembly line at Ford’s plant in Dearborn, Mich. The new version is 700 pounds lighter, owing to the body consisting almost exclusively of aluminum, instead of heavier steel.
Although the truck’s gas-mileage figures won’t be announced by the company until later this month, AP’s story notes:
The company says the 2015 truck will have from 5 percent to 20 percent better fuel economy than the current version, which gets up to 23 mpg. A figure in the higher end of that range might convince some buyers to switch brands, says Jesse Toprak, chief sales analyst for the car buying site Cars.com.
Fields told CNBC’s “Squawk Box” program that better fuel efficiency has been the “biggest customer unmet need, the biggest dissatisfier” in the past.
What about the effect cheap gasoline has on buyer behavior? He was asked whether consumers care less about fuel economy when gasoline is as cheap as it has suddenly become — around $3 a gallon, or even less in some places.
“They’re much smarter these days,” Fields said, adding that prices are volatile. “Our long-term view is, over time, the price of a barrel of oil is gonna go up. It’s a non-renewable resource.”

Things have always been a little easier in Europe when it comes to saving gas and adopting different kinds of vehicles. The distances are shorter, the roads narrower, and the cities built more for the 19th century than the 21st.
Europeans also have very few oil and gas resources, and have long paid gas taxes that would make Americans shudder. Three to four times what we pay in America is the norm in Europe.
Thus, Europeans have always been famous for their small, fuel-sipping cars. Renault was long famous for its Le Cheval (the horse), an-all grey bag of bones that’s barely powerful enough to shuttle people around Paris. The Citroën, Volkswagen and Audi were all developed in Europe. Ford and GM also produced models that were much smaller than their American counterparts. Gas mileage was fantastic — sometimes reaching the mid-40s. A big American car getting 15 miles per gallon and trying to negotiate the streets of Berlin or Madrid often looked like a river barge that had wandered off course.
More Europeans also opt for diesel engines instead of conventional gasoline — 40 percent by the latest count. The overall energy conversion in a diesel engine is over 50 percent and can cut fuel consumption by 40 percent. But diesel fuel is still a fossil fuel, which have a lot of pollution problems and don’t really offer a long-range solution. So, Europeans decided that it’s time to move on to the next generation.
Last week the European Union laid down new rules that will try to promote the implementation of all kinds of alternative means of transportation, making it easier for car buyers to switch to alternative fuels. The goal is to achieve 10 percent alternative vehicles by 2025 over a wide range of technologies, removing the impediments that are currently slowing the adoption of alternatives. If everything works out, tooling around Paris in an electric vehicle within a few years without suffering the slightest range anxiety would become a reality.
By the end of 2015, each of Europe’s 28 member states will be asked to build at least one recharging point per 10 electric vehicles. Since the U.K. is planning to have 1.55 million electric vehicles. That would require at least 155,000 recharging stations, which is a pretty tall order. But members of the commission are confident it can be done. “We can always call on Elon Musk,” said one official.
For compressed natural gas, the goal is to have one refueling station located every 150 kilometers (93 miles). This gives CNG a comfortable margin for range. With liquefied petroleum (LPG) it will be for one refueling station every 400 kilometers (248 miles). These stations can be further apart because they will mainly be used by long-haul trucks travelling the TEN-T Network, a network of road, water and rail transportation that the Europeans have been working on since 2006.
Interestingly, hydrogen refueling doesn’t get much attention beyond a sufficient number of stations for states that are trying to develop them. There is noticeably less enthusiasm for hydrogen-powered vehicles than is expressed for EVs and gas-powered vehicles. All this indicates how the hydrogen car has become a Japanese trend while not arousing much interest in either Europe or America.
At the same time, Europeans are planning very little in the way of ethanol and other biofuels (they also mandate 20 percent ethanol in fuel). Sweden is very advanced when it comes to flex-fuel cars. They have been getting notably nervous about the misconception that biofuels are competing with food resources around the world — Europe does not have its own land resources to grow corn or sugarcane the way it is being done in the United States and Brazil. Europe imports some ethanol from America but it is also now developing large sugar-cane-to-ethanol areas in West Africa.
Siim Kallas, vice president of the European Commission for TEN-T, told the press the new rules are designed to build up a critical mass of in order to whet investor appetites for these new markets. “Alternative fuels are key to improving the security of energy supply, reducing the impact of transport on the environment and boosting EU competitiveness,” he told Business Week. “With these new rules, the EU provides long-awaited legal certainty for companies to start investing, and the possibility for economies of scale.”
Is there any chance that the public is going to take an interest in all this? Well, one poll in Britain found last week that 65 percent would consider buying an alternative fuel car and 19 percent might do it within the next two years. Within a few years they find the infrastructure ready to meet their needs.
When he died, the patriot Paul Revere was embalmed in V8 juice, tanning lotion and several energy drinks. Surprisingly, he reappeared at a relatively recent conference of the Massachusetts Association of Automobile Dealers, looking fit and ready for another ride. The dealers had prayed for his second coming. They hoped that even though his previous ride was only one horsepower, he would consent to try a low-horsepower vehicle and ride the state, warning their brave residents that Tesla is online and in-store sales of electric cars coming. The dealers’ marketing folks felt that a reincarnated Revere would do wonders for their shaky image as wheeler dealers (excuse the pun). His deep, holier-than-thou, Fred Thomas-type voice (you know, the actor-turned-politician-turned-actor who now sells most anything on TV for money) would convince all but his former peer group (dead people) that Tesla was anti-American.
“What did Tesla do wrong,” asked Revere? Oh, it’s trying to sell its non-horse, torque-engine vehicles directly to modern-day patriots. Can you imagine euthanizing horsepower? Tears came to Revere’s eyes. But there’s more, paraphrasing a former automaker and cabinet officer Charles Wilson, one of the dealers indicates that what’s good for automobile dealers was and will always be good for America. What Elon Musk, the head of Tesla Motors, wants to do is eliminate dealerships. If the present case before the courts in Massachusetts is won by Tesla and Teslas are sold online, from a storefront, or shopping mall, surely Ford, Chrysler and General Motors will not be far behind. Forget capitalism, forget free markets, forget competition, even forget, Paul, your membership in the old Tea Party in Boston (you know, the taxation-without-representation crowd). Forget everything you fought for. By eliminating dealerships, Tesla will cost jobs. Dealers soon will have to close their doors. Bypassing dealers to sell cars will also first limit and then end our community philanthropy — you know, Little League teams, Fourth of July concerts, community picnics, jerseys for kids etc. Tesla’s headquarters is in California, and it’s a crazy state with Hollywood and all that. Californians act like foreigners. Tesla’s founder believes in global warming, he isn’t satisfied with life in America and he is developing a spaceship where the elite can, someday soon, travel to a second home and ruin our local economy. Losing dealers will make every community less American. Sure, vehicle costs may come down and emissions may improve, but what American is unwilling to pay extra to save his or her friendly auto dealer?
Revere was puzzled. He was a merchant way back then and he believed that competition and the free market were part of the American Dream. (To be honest, he also feared riding and did not understand how he could ride a multiple-horse powered vehicle. He had only mounted one horse.)
But he understood what the dealership folks were trying to tell and sell him. While in his heart, he was a bit ambivalent, he finally said he would do the famous ride again, and this time, because mileage capacity had increased and population of Massachusetts had grown, he agreed to try to go farther west than in his famous, poet-legitimized and sanctified ride.
But just as he gave them the okay, the dealerships received an email from a colleague in Boston that Tesla had won in the Massachusetts court. One dealer started crying. Several others criticized “those activist judges.”
Revere asked to read the email. It indicated that the Massachusetts Supreme Judicial Court unanimously determined that the Mass. State Automobile Dealers “lacked standing to block direct Tesla sales under a state law designated to protect franchises owners from abuses by car manufacturers” (Reuters, Sept. 15, 2014). Succinctly, the law was tied to the franchise relationship rather than unaffiliated manufacturers like Tesla.
The court’s finding should make it easier for Tesla to secure positive rulings in many other states. Earlier this spring, senior officials from the Federal Trade Commission strongly indicated that laws outlawing direct sales harmed consumers. Revere, after looking at the email, felt guilty that he had all but agreed to replicate his famous ride. But he was consoled by the fact that freedom and competition won out, at least in the Tesla case in Massachusetts, and that at least consumer democracy was alive and well in the state. He couldn’t help but muse on the fact that Texas, a state supposedly committed to minimal regulation and almost zero interference by government concerning businesses and citizens’ lives, turned its back on Tesla because of lobbying by dealers. Tesla cannot sell directly in Texas. But, as Ralph Waldo Emerson suggested, “foolish consistency is the hobgoblin of little minds.” After driving a Tesla (with no horsepower), Revere went back to the halo- lit neter lands happy. We haven’t heard from him since. But on faith alone, his experience with reincarnation likely would have made him a fan of Tesla’s electric cars and other alternative fuels.
To understand why hedge fund managers and speculators like biofuels, it is necessary to understand what has always driven the fuel that Henry Ford envisioned would power his first Model T’s. Originally, biofuels were seen as the solution to the possibility of a dwindling supply of fossil fuels as well as rising cost of these fuels. But, biofuels come with their own set of challenges. To understand what is now driving this sector, we need to understand the environmental impact of biofuel development as well as the state of the fossil fuel marketplace.
If there’s an Achilles’ heel to the efforts being made to introduce compressed natural gas (CNG) into the country’s vehicles, it is that somebody is going to come along with a liquid fuel that works much better.
CNG has many things going for it. Natural gas is now abundant and promises to stay that way for a long time. That puts the price around $2 a gallon, which is a big savings when gas costs $3.50 and diesel costs $3.70 per gallon. Trucks — mid-sized delivery trucks and big 18-wheelers — are the target market. Delivery vans usually operate out of fleet centers where a central compressor can be installed to service many vehicles. Meanwhile, pioneering companies such as Clean Energy Fuels are busy building an infrastructure at truck stops along the Interstate Highway System to service long-hauling tractor-trailers on their cross-country routes.
But there is a weakness. As a gas, CNG requires a whole new infrastructure. Compression tanks must be built at gas stations, much stronger than ordinary gas tanks and tightly machined, so gas does not escape. Even under compression, CNG has a much lower energy density than gasoline. This requires special $6,000 tanks that must still take up more space. In passenger vehicles they will devour almost all the trunk space, which is why vendors are concentrating on long-distance tractor-trailers.
As a result, there always seems the chance that some liquid derivative of methane is going to come along and push CNG off the market. Methanol has been a prime candidate since it is already manufactured in commercial quantities for industrial purposes. M85, a mixture of 85 percent methanol and 15 percent gasoline, is legal in the United States, but has not been widely adopted.
Now a new candidate has emerged in the long-distance truck competition — dimethyl ether or “DME.” Two methane ions joined by a single oxygen molecule, DME is manufactured from natural gas and has many of the same properties as methanol. It is still a gas at room temperature but can be stored as a liquid at four atmospheres or -11o F. It can also be dissolved as a gasoline or propane additive at a 30-70 percent ratio. In 2009 a team of university students from Denmark won the Shell Eco Marathon with a vehicle running on 100 percent DME.
So is it practical? Well, we’ll soon find out. Volvo has just announced it will release a version of its D13 truck in 2014 that runs on DME. At the same time, Volvo pushed back the launch of its natural gas version of the same line, meaning it may be changing its mind about which way the technology is going to go. In case you haven’t been keeping abreast, Volvo is now the largest manufacturer of heavy trucks in the world, having acquired Mack, America’s oldest truck company, in 2000.
So does that mean that CNG may turn out to be a dead end and Clean Energy Fuels is going to get stuck with a lot of unused compressor pumps? Well, hold on a minute. Technology does not stand still.
Last week at the Alternative Clean Transportation Expo in Long Beach, Calif., Ford and BASF unveiled a new device for the Ford F-450 CNG fuel tank. It’s called a Metal Organic Framework (MOF), a complex of clustered metal ions built on a backbone of] rigid organic molecules that form one-, two-, or three-dimensional structures. Lots of surface area is created, making MOFs porous enough to hold large amounts of gaseous material such as methane.
MOFs create the possibility that on-board CNG tanks will not have to operate under extremely high pressure or extremely low temperatures. Like a metallic sponge the high-surface material soaks gas right up, where it can be easily dislodged as well. According to BASF and Ford, the same amount of natural gas that requires 3,600 pounds per square inch (PSI) can be stored in an MOF tank at close to 1,000 PSI. That makes a big difference when it comes to designing an automobile.
So does that mean natural gas is going to be able to hold its own against DME and other liquid competitors? Well, wait a minute, there’s still more. Not only is MOF technology good at storing methane, it also works with hydrogen! That means the hydrogen-fuel cell — still the favorite among Japanese manufacturers — may be able to work its way back in the game as well.
In fact, Ford isn’t playing any favorites. Equipped with its new MOF tanks, the F-450 will offer drivers a choice of seven — that’s right, seven — different fuel options using the same internal combustion engine. “Ford has no idea which of these fuels will make the most sense,” Ford’s Jon Coleman told Jason Hall of Motley Fool. “So we need to build vehicles that have the broadest capability and the broadest fuel types so our customers can choose for themselves.”
That’s the name of the game. It’s called Fuel Freedom.
The Energy Information Administration has done us an enormous favor by producing a simple chart to make sense of where the development of energy storage technology is going. Energy storage, as the EIA defines it, includes heat storage, and a quick look at the chart reveals that those forms that involve sheer physical mechanisms – pumped storage, compressed air and heat reservoirs – are much further along than chemical means of storage, particularly batteries.
The EIA divides the development of technologies into three phases – “research and development,” “demonstration and deployment” and “commercialization.” It also ranks them according to a factor that might be called “chances for success,” which is calculated by a multiple of capital requirements times “technological risk.”
As it turns out, only two technologies that could contribute to transportation are in the deployment stage while three more are in early development. The two frontrunners are sodium-sulfur and lithium-based batteries while the three in early stages are flow batteries, supercapacitors and hydrogen. The EIA refers to hydrogen as one of the ways of storing other forms of energy generation, particularly wind and solar. But hydrogen is also being deployed in hydrogen in hydrogen-fuel-cell vehicles that have already been commercialized.
Other than building huge pumped-storage reservoirs or storing compressed air in underground caverns, the chemistry of batteries is the most attractive means of storing electricity, which is the most useful form of energy. Batteries have always had three basic components, the anode, which stores the positive charge, the cathode, which stores the negative charge, and the electrolyte, which carries the charge between them. Alexander Volta designed the first “Voltaic pile” in 1800 by submerging zinc and silver in brine. Since then, battery improvements have involved finding better materials for all three components.
Lead-acid batteries have become the elements of choice in conventional batteries because the elements are cheap and plentiful. But lead is one of the heaviest common elements and becomes impractical when it comes to loading them aboard a vehicle.
The great advantage of lithium-ion batteries has been their light weight. The lithium substitutes for metal in both anode and cathode, mixing with carbon and iron phosphate to create the two charges. Li-ion, of course, is the basis of nearly all consumer electronics and has proved light and powerful enough to power golf carts. The question being posed by Elon Musk is whether they can be ramped up to power a Tesla Model S that can do zero-to-60 with a range of 300 miles.
Tesla is not planning any technological breakthrough, but will use brute force to try to scale up. Enlarging li-ion batteries tends to shorten their life so the Tesla will pack together thousands of small ones no bigger than a AA that will be linked by a management system that coordinates their charge and discharge. Musk is betting that economies of scale at his “Gigafactory” will lower costs so that the Model X can sell for $35,000. According to current plants, the Gigafactory will be producing more lithium-ion batteries than are now produced in the entire world.
In the sodium-sulfur battery, molten sodium serves as the anode while liquid sodium serves as the cathode. An aluminum membrane serves as the electrolyte. This creates a very high energy density and high discharge rate of about 90 percent. The problem is that the battery must be kept at a very high temperature, around 300 degrees Celsius, in order to liquefy its contents. A sodium-sulfur battery was tried in the Ford “Ecostar” demonstration vehicle as far back as 1991, but it proved too difficult to maintain the temperature.
Flow batteries represent a new approach where both the anode and cathode are liquids instead of solids. Recharging takes place by replacing the electrolyte. In this way, flow batteries are often compared to fuel cells, where a steady flow of hydrogen or methane is used to generate a current. The great advantage of flow batteries is that they can be recharged quickly by replacing the electrolyte, rather than taking up to 10 hours to recharge, as with, say, the Chevy Volt. So far flow batteries have relatively low energy density, however, and their use may be limited to stationary sources. A German-made vanadium-flow battery called CellCube was just installed by Con Edison as a grid-enhancement feature in New York City this month.
Supercapacitors use various materials to expand on the storage capacity devices in ordinary electric circuits. They have much shorter charge-and-discharge cycles but only achieve one-tenth of the energy density of conventional batteries. As a result, they cannot yet power vehicles on a stand-alone basis. However, supercapacitors are being used to capture braking energy in electric trams in Europe, in forklifts and hybrid automobiles. The Mazda6 has a supercapacitor that uses braking energy to reduce fuel consumption by 10 percent.
The concept of “storage” can be also be expanded to include hydrogen, since free hydrogen is not a naturally occurring element but can store energy from other sources such as wind and solar. That has always been the dream of renewable energy enthusiasts. The Japanese and Europeans are actually betting that hydrogen will prove to be a better alternative than the electric car. Despite the success of the Prius hybrid, Toyota, Honda and Hyundai (which is Korean) are putting more emphasis on their fuel cell models.
Finally, methanol can be regarded as an “energy storage” mechanism, since it too is not a naturally occurring resource but is a way to transmit the potential of our vast reserves of natural gas. Methanol proved itself as a gasoline substitute in an extensive experiment in California in the 1990s and currently powers a million cars in China. But it has not yet achieved the recognition of EVs and hydrogen – or even compressed natural gas – and still faces regulatory hurdles.
All these technologies offer the potential of severely reducing our dependence on foreign oil. All are making technical advances and all have promise. Let the competition begin.
