Can algae become the new biodiesel?

Supporters call it “clean diesel” to differentiate it from “biodiesel,” and indeed, there is a difference. Soybeans, the main feedstock for biodiesel, have only a 2-3 percent oil content. Some species of algae can have up to 60 percent oil content. This reduces the land requirements for growing a crop by a factor of 30.

So is algae biodiesel one of those great ideas that is always just over the horizon? Or has it germinated long enough that it may finally about to become a reality? The outcome still appears to be up for grabs.

The term “algae” actually cover a whole spectrum of organisms, from the 20-foot ribbon-like “seaweed” that grows in ponds and along littoral shores to the mid-ocean, microscopic “plankton” that is the diet of whales. All have one thing in common – they use carbon and sunlight to photosynthesize organic material. And they are good at it. Some species can double their mass within 24 hours. Thousands of species thrive in varying environments. Last summer, a red algae “tide” that feeds on farm runoff at the mouth of the Mississippi River “bloomed” to cover 5,000 square miles of the Gulf of Mexico, killing all manner of birds, fish and marine life, including hundreds of manatees. “If we can figure out how to make energy out of that,” President Obama told an audience at the University of Miami, “we’ll be doing alright.”

The idea of harvesting algae for energy was first suggested by Richard Harder and Hans von Witsch, two European scientists at the outbreak of World War II. Nothing much developed, however, and interest didn’t revive until the Energy Crisis of the 1970s, when the Department of Energy set up an Aquatic Species Program to pursue research.

Funded with $25 million over the next 18 years, the Aquatic Program investigated thousands of species, finding the Chlorella genus the most promising. It also made an important discovery. When Chlorella is deprived of nitrogen, it can increase its lipid (fat and oil) content to a remarkable 70 percent of mass! Remember, soybeans are only 2-3 percent lipids. But this created a conundrum. While depriving algae of nitrogen might may increase lipid content, it also severely inhibited growth. The Aquatic Program had not yet resolved this dilemma when it was disbanded in 1996.

Private companies picked up the research, however, and have tried to overcome it with genetic engineering. While pursuing this, they have developed two methods of cultivation. The easiest is to grow algae in open pools or “raceways” that devour large areas of land, since sunlight can only penetrate a few centimeters into the algal mat. The problem here is that most species are highly sensitive to variations in acidify, temperature and humidity. Their high lipid content also means they synthesize fewer proteins, which makes them extremely vulnerable to invasive species. This makes it very difficult to bring them up to commercial scale.

The more advanced technology is “photobioreactors,” conducted in large networks of glass or plastic tubes. The system overcomes environmental difficulties but is very expensive. In 2009 Exxon combined with J. Craig Venter, the decoder of the human genome, to try to develop a commercial method for developing algae-based fuels. After investing $600 million, however, Exxon pulled out of the enterprise in 2013, saying commercialization was 25 years away.

Nevertheless, several small companies say they are now making progress. Algenol, a Fort Myers, Fla. company, says it has developed a revolutionary “3rd generation” technology that can produce ethanol, jet and diesel fuel 8,000 gallons per acre, 18 times the output of corn-based ethanol, at $1.25 per gallon. Sapphire, a San Francisco company, has opened a 100-acre Green Crude Farm in New Mexico and hopes to be producing 100 barrels a day next year with full-scale commercialization by 2018. And Aurora Algae, a Hayward, Calif. firm which has operated a test facility in Western Australia for the last three years, has just announced an open-pond operation in Harlingen, Texas that it hopes to expand to 100 acres.

There is one great irony to all this. A full-blown algae industry already exists, providing feedstock for food additives, cattle silage and nutritional and pharmaceutical products. Some highly specialized fatty acids derived from exotic species can fetch $10,000 per gallon. In fact, the current industry sees algae-for-fuel as a rather low-grade use. “Until more federal funding is available, my members are going to continue growing for the higher-value products,” Barry Cohen, executive director of the National Algae Association, told Slate’s John Upton. “We have algae companies that are growing for the ingredients industry, the food industry and the nutraceutical industries. If they can grow the right species, those companies will buy every drop they can make.”

What makes these operations viable, of course, is their high-value end products, which cover the costs of growing algae in commercial quantities. An algae-for-fuel industry will either have to: a) develop new species that are much more efficient or b) perfect mass-production techniques that can bring prices down to an acceptable range. Only then will “clean diesel” become a competitor. For now, the industry seems headed in the right direction.

Clean Energy Fuels sees daylight ahead

Wall Street was abuzz last week as Clean Energy Fuels, the leading supplier of natural gas for use in delivery and heavy-duty trucks, jumped 11 percent in one day after a long slump in which investors were questioning its business model.

“We’re at the very beginning of a major shift to natural gas for trucking – a shift that could take a decade before the growth slows – and Clean Energy Fuels is the leader in the market,” added Jason Hall of Motley Fool, who had been skeptical of the company in the past but is now turning enthusiastic.

“Natural gas vehicles are here to stay,” added James E. Brumley on SmallCap Network, in one of the many enthusiastic endorsements the company received last week. “So Clean Energy Fuels is very much a right-time, right-place idea. It’s not just that the company is the biggest and the best at what it does. There’s a market of scale for what it has to offer.”

It hasn’t been easy. The company, the brainchild of legendary oilman T. Boone Pickens, seemed poised for growth last year but suddenly hit a sudden downdraft in January. Skepticism grew over whether compressed natural gas (CNG) or liquid natural gas (LNG) would be the best substitute for diesel in heavy-duty trucks. The debate is really inconsequential since the two are interchangeable – LNG for large-scale storage and transport with some use in the biggest rigs and CNG for fueling smaller commercial vehicles. Nevertheless, the controversy drove down CEF’s stock price 25 percent since the first of the year.

“Much of the conversation in the investor community over the past six months has been dominated by the false idea that CNG and LNG were competing fuels,” wrote Hall in a recent evaluation. “But while we’ve been arguing, Clean Energy Fuels has been opening stations for trucks across the country. And the company is a leader in both.”

Once again, it seems to have been a case of investors becoming absorbed in short-term focus while ignoring the long-term prospects of the company. True, Clean Energy Fuels has not yet delivered a profit but its progress in building infrastructure to enable us to use significant portions of our natural gas resources as a substitute for diesel fuel has been significant. Here’s what the company has accomplished so far:

  • Clean Energy Fuels has delivered 800 million gallons of CNG and LNG to light and heavy-duty trucks.
  • The company has built approximately 500 fueling stations across the country.
  • It has installed over 1,500 compressors for delivering CNG to vehicles worldwide.
  • It has two LNG production plants.
  • It has 60 LNG tankers making 5,000 deliveries every year.
  • It has two renewable natural gas plants producing bio-methane.
  • It has 39 major airport fueling stations.
  • It now fuels over 35,000 trucks, large and small, with CNG each day.

As you can see, this is no fly-by-night operation. Whether the company is profitable or not right now, Pickens is obviously in it for the long haul.

Clean Energy Fuels’ long-term goal is a “CNG superhighway” that will offer fueling stations to long-haul trucks along all the major interstates that crisscross the country. But its major success to date has been in servicing fleet vehicles for delivery companies and municipalities.

  • CEF currently services 230 trucks a day for UPS with big plans for expansion.
  • CEF has contracts with Owens-Corning, Lowe’s, Proctor & Gamble and other commercial establishments’ fleet owners for their delivery vehicles.
  • Garden City Sanitation of San Jose has converted 23 refuse trucks to natural gas using CEF’s services.
  • CEF will be fueling Kroger’s new 40-unit fleet of LNG trucks later this year.

Analysts believe that refuse and delivery fleets, especially those that are garaged overnight and can be refueled at a central CNG station, will become one of the company’s major markets.

CEO Andrew Littlefield just announced a loss in revenues for the first quarter of 2014 but said this was because of the expiration of the federal volumetric excise tax credit (VETC), which had provided $26 million in 2013. Overall, the trend is definitely upward:

  • LNG fuel deliveries increased 22 percent to 16.7 million gasoline gallon equivalents.
  • CNG deliveries increased 16 percent.
  • When the VETC is excluded, overall revenues were up 43 percent. 
  • Sales of Redeem, the company’s renewable bio-methane product, increased 45 percent.

Sean Turner, COO for Gladstein, Neandross & Assoc., a leading consulting firm for the development of alternative fuels, notes that the NGV market in the United States is actually larger than in countries such as Argentina and Pakistan, which have been at it for a longer time. “While North America might lag behind in the adoption curve of other countries, natural gas usage per vehicle is actually near the top worldwide,” he said. “This is because other countries have tended to employ NGVs for passenger cars, whereas the U.S is now concentrating on medium-sized and heavy-duty trucks.” And as T. Boone Pickens likes to point out, natural gas will be unrivaled in this marketplace since electric vehicles cannot produce the torque needed to power those long-haul vehicles.

Whether all this makes Clean Energy Fuels a hot stock again is something Wall Street will have to decide. But in terms of moving America toward greater reliance on homegrown natural gas, the news is all favorable.

Let freedom ring: Oil companies, capitalism and fuel choice

It’s a free county, ain’t it? Americans have many choices that are denied to citizens of other less-fortunate nations. But we forget how many decisions are made for us, sometimes out of necessity, such as paying taxes; sometimes out of greed, such as the monopolistic actions of oil companies in denying many Americans the ability to purchase alcohol-based fuels at their corner gas station. Try it someday! On your way home from work, on your shopping trip to your friendly supermarket or on your way to see a movie at your favorite theater, make a stop for fuel at a gas station. Make sure to have some gasoline in your tank, because it likely will take you a lot of time to find a gas station that sells E85 or even E15.

Now, I went to Harvard Law School for four days, before I decided that there were too many lawyers around and memorizing case studies was not my forte. But Harvard provides significant value added, apart from being near Harvard Square and Boston. I was exposed to terms and content related to antitrust, restraint of trade, collusion and monopolies. Now, I didn’t stay long enough to know whether those concepts applied to oil companies that restrict consumer choices of alternative fuel. Probably not, because I am sure, by now, one of my Harvard colleagues would have filed a well-reimbursed case to break open the fuel market to options like ethanol, methanol and more. But whether legal or not, oil companies deserve their comeuppance for limiting many of us who, too often, are required to use more expensive, environmentally harmful gasoline, instead of existing, safe, alternative fuels.

How do they do this? Well, if you are a gas station owned or franchised by an oil company, your contract and rules related to behavior often prevent you from adding a pump or adding to an existing pump to sell E15 or E85. As relevant, since oil companies generally require the stations they own to buy fuel from them, and since they don’t sell E15 or E85, adding a pump would be akin to waiting for the hereafter (and acting on faith that you will get there).

Wait, there is more! Every now and then an oil company wants to publicly show it is a bit beneficent (for image purposes), but don’t hold your breath with respect to proof that image and reality are the same. Sure, you might find an alternative-fuel pump near the rear side of the garage proximate to the men’s room, or, if you are lucky, on the side of the station near the air pump. Most oil-company-owned stations and franchisees are generally precluded from putting an alternative-fuel pump under the covered island or space out front. They also face restrictions on advertising alternative fuels as an available product and oil-company pricing limits competition from alternative fuels.

Congress has refused to enact open fuels legislation, which would require oil companies to open up their gas stations to other fuels. Ongoing efforts by public and private sector advocates, as well as nonprofit groups, to encourage policies that would convert older cars to flex-fuel vehicles and to encourage Detroit to build more FFVs could well lead to a large consumer market for alternative fuels and generate a positive market reaction among independent gas companies and, perhaps, even some smart oil companies. While I have been wading through the pros and cons of allowing oil companies to increase exports to other nations, I do believe that if increased exports are in the nation’s future, they should be approved only if the oil companies agree to require their stations and franchises to offer alternative fuels in a primary space alongside gasoline. A bit of tat for tat is in the public interest. Let freedom ring for consumer! Let capitalism mean competition for gasoline and alternative fuels at your nearby gas station! Oh, I forgot, alternative fuel station!

From lab to market, it’s a long haul

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.

Right, wrong and indifferent — the AAA, oil and alternative fuels

My favorite automobile service group — the AAA — has once again treaded without fear or trepidation into analysis. Remember earlier, when it suggested that E15 harms engines, based on what looked like an oil-industry-generated study? The AAA’s methodology was weak and its conclusions suspect, a judgment supported by the EPA’s response. According to the agency, AAA’s conclusions were erroneous and based on a limited sample. EPA’s own findings were generated from a relatively large sample of cars, indicating that E15 is safe for most engine types and reaffirmed the wisdom of its approval of E15 usage.

I was surprised to find an article in Oil Price by blogger Daniel Graeber, based to a large degree on comments from AAA’s Michael Green suggesting that the oil shale boom has prevented gas prices from going higher than they are now. Graeber approvingly quoted Green, who said, “Sadly, the days of cheap gasoline may never return for most American drivers despite the recent boom in North American crude oil production.” Assumedly, Green meant that the cost of drilling tight oil will remain high and the costs per barrel of oil will follow suit.

Green apparently went on to indicate that political leaders, particularly, members of Congress who argue for a drill-baby-drill policy, are wrong to link more wells to significant price relief for folks who find gas costs a real problem.

The AAA is right when it suggests that, despite the oil shale boom and signs of increasing demand in America, refineries are sending increased amounts of oil-based products overseas. Understandably, their patriotism doesn’t extend to accepting a lower price for oil in the U.S. when they can get higher prices overseas.

The article appears inconsistent, when at one point it mentions that crude oil inventories are running above average, and later blames current exports for low supplies and low supplies for preventing a drop in prices at the pumps.

Both are correct in indicating sales of oil products abroad probably do have an effect on costs-up to now probably marginal. Certainly, if Washington extends export privileges, increased sales of oil abroad may have a more significant impact on consumer costs. More relevant, however, concerning gasoline costs at the pump, will be economic recovery in the U.S., investor speculation and the oil sector’s ability to manage prices.

Cheap oil has been, recently, and likely will be in the future, a fantasy. The cost of oil per barrel has hovered at around $100 and upward for an extended period, and drilling in shale is relatively expensive. Continuous exogenous and existential (don’t you like those words — they create great passion and emotion) threats from the Middle East and Eastern Europe, also, will likely tilt oil prices upward in the near future.

I would commend the AAA, assumed by many to be the leading advocate for automobile owners in the nation, for grasping the fact that the behavior of producers is likely to lead to higher gas costs and create burdens, particularly for low and moderate-income groups. Now with this knowledge, shouldn’t the AAA argue for breaking oil’s near monopoly on fuel? If the AAA was really interested in helping vehicle owners lower their cost of fuel, it might take the lead in arguing for choice at the pump. Wouldn’t it be great if they really stood up for more open fuel markets as well as alcohol-based transitional fuels, such as ethanol and methanol? Competition at the pump from flex-fuel vehicles, combined with conversion of older vehicles to flex-fuel cars would, over time, mute increases in gas prices and, at the same, time generate environmental benefits for a better America. Support for alcohol-based fuels is consistent with support for renewable fuels, if one is concerned about the environment and GHG emissions. Let’s bring them on as fast as we can. But let’s acknowledge that renewable fuels are not really ready yet for prime time. They are too expensive for many Americans and their technical limitations, particularly concerning electric batteries, are not yet coincident with the desires of most Americans.

CNG moves ahead on all fronts

The effort to substitute compressed natural gas for foreign oil in our gas tanks is moving ahead on all fronts across the country, in scores of municipal departments that are converting their fleets, in new gas stations that are opening and with entrepreneurs who are looking for ways to speed up the conversion.

Leading the pack is Clean Energy Fuels, T. Boone Pickens’ effort to put the nation’s natural gas resources to work in the transport sector. Clean Energy Fuels has targeted long-distance, heavy-duty trucks, which tend to stay on the Interstate Highway System and can be services at massive truck stops. In Pennsylvania, for instance, Clean Energy Fuels is building stations in Pittston and Pottsville that will serve trucks on heavily the traveled I-81 and I-476. They are scheduled to open later this year.

But much of Clean Energy Fuels’ real success is coming from the fleet conversion for major shipping firms that rely heavily on truck transportation. The company has had particular success with UPS. Fueling depots were recently opened in Oklahoma City and Amarillo, Texas. The carrier E.J. Madison, LLC has deployed a fleet of 20 long-haul LNG trucks that will utilize a CEF network of stations that stretches from Los Angeles to Jacksonville, Florida. Jacksonville is emerging as a hub of CEF activity as the company has opened a liquid natural gas (LNG) terminal there as well. LNG is more difficult to handle than compressed natural gas but has much greater energy density.

Rapidly expanding in Florida, CEF has just announced a grand opening of a CNG filling station that will service the Hillsborough Area Regional Transit Authority (HART), which provides public transportation throughout the Tampa metropolitan area. The opening kicks off a plan to convert HART’s entire fleet of public services buses and vans to compressed gas.

Just last week Clean Energy Fuels CEO Andrew Littlefair was in the news telling The Motley Fool that Tesla’s electric cars will not be in competition with CEF’s efforts. “Tesla and electric vehicles are really great for certain applications,” he told interviewer Josh Hall. “But hauling 80,000 pounds of cargo, natural gas is really well suited for that.”

However, even if Clean Energy Fuels doesn’t think CNG can compete with electric at the passenger-car level, others do. Last week the Wawa convenience store chain announced it will partner with South Jersey Gas to open CNG fueling stations in southern New Jersey. “Compressed natural gas gives us an opportunity to increase the convenience we offer our customers and positions us for the future as well,” Brian Schaller, vice president of fuel for Wawa told the press. “We’re excited about the growth potential.” With 600 stores on the East Coast from New Jersey to Florida, Wawa has plenty of room to grow.

Pennsylvania is becoming a hotbed of compressed gas progress as the state seeks to take advantage of the Marcellus Shale. The state has adopted a funding program to help businesses convert. One of the first to take advantage is Houston-based Waste Management, which received an $806,000 grant from the State Department of Community & Economic Development to switch 25 of its waste and recycling collection vehicles to CNG. Pennsylvania-American Water Company has also announced plans to convert its fleet with a $315,000 state grant. American Water, the largest water utility in the state, operates out of Scranton.

Nebraska is a long way from any natural gas drilling but the Uribe Refuse Services company of Lincoln has announced it will convert its entire fleet of 17 trucks to natural gas over the next few years. The first trucks were displayed in the city last week on Earth Day.

Oklahoma is a big oil-and-gas producing state and is making a major effort to convert state vehicles to natural gas. In 2011 Gov. Mary Fallin joined 15 other states in a multi-state memorandum of understanding committing them to purchase NGVs for the state fleet. The state now has 400 CNG vehicles and is pushing the federal government to convert its fleet in the state as well. Oklahoma is building CNG gas stations to match and now stands third in the nation behind California and New York.

The natural gas industry is putting its shoulder to the wheel on this effort. The American Gas Association and America’s Natural Gas Alliance (ANGA) have teamed up to sponsor “Add Natural Gas (+NG),” an effort that is encouraging entrepreneurs and mechanics to convert ordinary passenger cars already on the road to CNG. “Fleets across the country are already using natural gas vehicles to save money and reduce emissions,” says the group’s website. “However, natural gas can be used to fuel any vehicle. To demonstrate this, we worked with automotive engineers to add natural gas as a fueling option for some of the most popular vehicles on the market today.”

Performance CNG LLC is a Michigan startup that has been inspired to take up the initiative. The company recently had a hybridized 2012 Ford Mustang GT demonstrated as part of +NG’s campaign and is currently trying to raise $55,000 in capital on Indiegogo, an international crowd funding site. More than half the money would go to EPA emissions testing.

Not everyone is convinced that CNG is the way to go. Clean Energy Fuel’s stock has done poorly since January, based on investor skepticism that its market is not that big and that some liquid natural-gas based fuel – methanol of butanol – will prove easier to handl

Rin Tin Tin, RINs and the price of ethanol

Is the son or daughter of Rin Tin Tin alive and well? For a while I thought he or she was, while catching up on my reading over the weekend. I kept reading articles about RINs (Renewable Identification Numbers), their possible impact on the ethanol market and relatively high ethanol prices, despite the apparent weakening of the ethanol market. There seemed to be RINs and more RINs on every page I turned! Because I hadn’t slept for two nights, I couldn’t really focus on the contents of the articles, but only on the dog Rin Tin Tin and his offspring. How many of you have done that? Come on, be honest. Don’t make me feel bad!

I felt guilty after it became obvious that my focus on Rin Tin Tin resulted from a tired brain and eyes. I am back to the complex world of RINs today. (I had a bit of sleep).

Okay, you ask, “What the hell are RINs?” They are sort of a pass at reflecting company fulfillment of government mandates concerning biofuels. For this article, think ethanol! They are issued at the point of ethanol production or the purchase of the fuel by companies. They are approved by the EPA. They reflect a credit that verifies that the required amount of ethanol has actually been blended into gasoline. Succinctly, the Renewable Fuel Legislation, now the law of the land, mandates that a Renewable Identification Number (RIN) must be attached to every produced or imported gallon of renewable fuel in the U.S. One more thing, RINs are separated from the batch of renewable fuel when it is blended with gasoline. This fact indicates compliance with the law and Renewable Volume Obligations (RVOs). Credits, at this juncture, can be used for trading purposes.

In 2012, before the EPA’s Nov. 2013 proposal to change RIN quotas and lower requirements for ethanol, the price of RINs was very volatile. Initially, they ranged around 1 to 10 cents a gallon. By spring of 2013, however, they were around $1.

Why the price increase and what does it bode for the price of ethanol in the future? Initially, the RINs were thought of as a way to encourage refiners to produce renewable fuels, like ethanol, and to “pay” for credits if they don’t “play” by  meeting fuel targets.

Part of the volatility and increase in costs of RINs, probably, has to do with speculation by banks and other financial institutions. Thomas D. O’Malley, chairman of PBF Energy, indicated in a recent New York Times article that financial institutions “helped transform an environmental program into a profit machine…These things were designed to monitor the inclusion of ethanol in the gasoline pool…They weren’t designed to become a speculative item. For the life of me, I can’t see the justification for it.” Interviews with members of the financial community, conducted by the New York Times, seem to suggest agreement with O’Malley.

According to the Times, speculation in RINs “could have consequences for consumers. In the end, energy analysts say, the outcome will be felt at the gas pumps — as the higher cost of the ethanol credits get tacked onto the price of a gallon of gasoline.” The Times reports that the “credits, which cost 7 cents each in January [2013], peaked at $1.43 in July, and [were] trading for 60 cents” in September. Jordan Godwin in the Barrel Blog indicated that like RINs in 2013, ethanol prices in 2014 are downright wacky. “In a matter of less than two months, ethanol prices went from six-month lows to eight-year highs.” Godwin and others blame delayed returning train cars during the winter and constraints on supply and production. I would add speculation by Wall Street and uncertainty as to the impact and longevity of EPA’s new regulations concerning the reduced mandates for ethanol and other biofuels. It’s a dilemma for proponents of alternative fuels. Less speculation regarding trading, sustained predictable production and refinement of the distribution system, (along with avoidance by some retailers and blenders to price ethanol well over costs) would facilitate more competition with gasoline at the pump. More predictable competition and larger sales at the pump of E15 and E85 would generate more private-sector fixes to the ethanol supply chain as well as likely stabilize prices and, over time, lower them. In light of ethanol’s benefits to the nation, wise folks might be asked to find policies and stimulate market behavior that permit the American people to have it both ways.

Take me shopping for eggs, copper and corn starch

Good news for a world often filled with bad news has recently been generated by two major U.S. universities, both in regards to the efficacy of alternative fuels. Maybe the announcements will lend confidence that America can find a way to balance economic growth with environmental concerns. Increasing success over time will mean that (paraphrasing in part, the late Sen. Robert Kennedy) the nation will not have to accept “what is” with respect to the dominance of gasoline as a fuel, but can consider “what could be” concerning the use of alternative, cleaner, safer, environmental-better and cheaper fuels.

Stanford University professors, in a paper co-authored by Dr. Matthew Kanan, assistant professor of chemistry, announced that they have developed a copper catalyst that can efficiently convert carbon monoxide and water into ethanol. Quoting from a recent MIT Technology Review (April 2014), “while the work is still experimental, it’s significant because the group was able to synthesize ethanol and other desired products with so little energy input.” The Stanford researchers envision a “two-step process in which carbon dioxide is first converted into carbon monoxide using either existing processes or more energy-efficient ones that are currently under development. Then, the carbon monoxide would be converted to ethanol or other carbon-based compounds electrochemically. The key to the new catalyst is preparing the copper in a novel way that changes its molecular structure.”

How long will it take to get from idea to market? If the copper-based process survives further lab tests and evaluations, and if it is then converted into a prototype that is able to produce ethanol fuel, a big push to convert the prototype to real-world status from both the private sector and government would be warranted.

Stanford’s “breakthrough” — if the process becomes marketable and can generate lower-priced, environmentally-safe ethanol that is capable of fueling flex-fuel vehicles (FFVs) and older, converted FFVs — will be significant, even perhaps a disruptive technology. With the proper support, hopefully in the not-too-distant future, increased use of the copper catalyst will minimize and maybe even end the food vs. fuel and land-use allocation fights, as well as help resolve GHG emissions and other pollutant issues that have sometimes frustrated the use of corn-based ethanol and muted receptivity to natural-gas-based ethanol. Technological improvements concerning production reflected in recent life-cycle analysis of corn-based ethanol and reasonable assumptions concerning the cost and environmental benefits of natural-gas-based ethanol, combined with the success of Stanford’s copper catalyst approach, could offer owners of FFVs (both converted and new vehicles) a wider variety of alternatives to secure ethanol that, clearly, will be cheaper, safer and better for the environment.

Stanford’s good news was matched by Cornell’s. Dr. Yingchao You and Dr. Hao Chen announced that they had discovered that a component of corn starch and the yolk shell structure of eggs improve the durability and performance of lithium batteries. In this context, they note that lithium-sulfur batteries are a very solid alternative to lithium-ion batteries. Stabilization problems related to its capacity can be resolved by using amylopectin, a polysaccharide (mainly good old corn starch).

Enveloping the battery’s lithium sulfur cathodes, with an encasing resembling the shell of an egg yolk (sulfur coated with an inexpensive polymer) also apparently improves the battery’s durability and performance.

Cornell has initiated a startup company to take the new and improved starch, egg-yolk shell battery to market. Maybe sometime soon, moderate and middle-income owners of electric cars that are less expensive than what is now available will be able to reduce their fear of driving long distances and feel confident about the life and efficiency of the batteries in their vehicles.

I avoided chemistry, physics and engineering in college. I knew I was not destined to become neither city planner nor designer at MIT when my first student-planned bridge went under water instead of over it. While my efforts were applauded by the Malthusians among my colleagues, they were not regarded highly by professors. Since graduation, unless supported by respected colleagues with a background in relevant sciences and engineering, I have been hesitant to suggest approval of science-driven energy innovations. I am a policy and program person. However, after review and discussions with trusted experts, I believe the Stanford and Cornell initiatives have a good chance to see the light of day, or, more appropriate, see the light in the market place. If one or both do, we will all be better off and the number of feasible alternative transportation fuels available to the consumer will grow. Hooray for copper, starch and eggs.

The Battle Over Ethanol Takes Shape

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.

Hawks Are Out Again: Mistakenly Casting Doubt on Ethanol

The Hawks are out again.  One of my favorite service organizations, the American Automobile Association (AAA), in conjunction with media outlets, has again attacked the use of ethanol in cars.  It’s quite sad.

I will still keep my membership card. The AAA is the Walmart, Costco or Nordstrom of the automobile industry when it comes to service at relatively low costs to its members.  If you get a flat tire on a sparsely traveled road when it’s raining or snowing, the AAA, following the Postal Service norm, “come rain or snow,” will get there reasonably quickly to help you.  Get stuck in your four story garage with a dead battery! Don’t fret or fear, your neighborhood AAA repair truck will be at your side within a relatively short time. It,generally, will “get you to your work on time.” Do I sound like Julie Andrews or the cast in “My Fair Lady?”

 

While I don’t lose sleep over the question (I only get two hours of sleep even without thinking about the AAA), I often wonder why the AAA appears to join with those, particularly in the oil industry, who seem to want to confuse flex fuel vehicle owners and owners of older cars able to convert their engines easily and cheaply, about the wisdom of using ethanol.

Conversion of older cars and extended use of already approved flex fuel cars as well as increased use of ethanol by both sets of vehicles  will result in many benefits, particularly when compared to gasoline.  For example, ethanol according to many, many independent studies by qualified researchers is a safer, cheaper, and more environmentally friendly fuel than gasoline.  While what is and what is not a fact often becomes a metaphysical question and 100% certainty becomes a question often for philosophers more than scientists, trust me — ethanol is a good but is not a perfect alternative fuel. It is better than gasoline.  Right now a perfect fuel does not exist! Remember that the enemy of the present good is often the distant perfect.

Despite AAA’s press releases, EPA studies involving more rigorous methodology, including strategic sampling of a range of cars, indicate that engine damage is almost a nonoccurrence when using E15.  E10 has been around for a long time with no discernable engine impact and E85, after extensive testing, has been approved for flex fuel cars.

Understandably, ethanol, given improvements in new car engines and tighter fuel standards, reflects fewer benefits than   shown in relatively recent studies concerning ghg emissions, and pollutants like SOx and NOx.  But ethanol still provides significantly more environmental benefits and less costs to the consumer now than gasoline.

The differences between ethanol and gasoline will become even more apparent if you assume that Americans use their God-given noggin and opt to convert their older cars to accept alternative fuels.  It’s cheap and safe and can be done with a kit, or with quick software or tuning fix for some cars.  Similarly, there are nearly 15,000,000 flex fuel cars in the U.S. Most owners do not know they have such a car. Look at the sticker in the back of the car or fuel cap.  You probably are the proud owner of a flex fuel vehicle and, once you recognize this fact, you can use ethanol without risk.  Using ethanol, both for flex fuel cars and converted older vehicles will likely lower your gasoline costs and will contribute to a healthier environment.  Tell your neighbors!  Tell your friends! Tell your significant other!  Tell your spouse!

Clearly, you will see the environmental benefits to your community, state and nation, if you abandon the conventional way of measuring emissions and pollutant reductions and use tons. The new graphic will portray a visible and important increase in the actual emissions and pollutants eliminated from the atmosphere.  It also will emphasize the importance of extending the number of vehicles that can use ethanol through conversion of older cars to flex fuel vehicles and the production of increased numbers of flex fuel vehicles.  If the owners of both sets of cars increasingly fuel their vehicles with mostly ethanol (an objective of a number of demonstrations and pilot programs in several states), the President’s desire to wean the nation off of gasoline will come closer to fruition.  The scale up will provide a transition approach to open fuel markets until competitive renewable fuels become ready for prime market time.
