President Obama, DOE boost alternate fuels

President Obama burnished his legacy as an environmentalist last week by mandating a huge cut in greenhouse gas emissions among federal vehicles. The aim is to cut emissions for 40 percent by the year 2025.

The executive order will increase the percentage of the government’s 636,000 vehicles that run on alternative fuels. Improved gas mileage on new internal combustion engines can account for only a small fraction of the required reduction, so the only alternative will be to increase the number of non-gasoline engines in the fleet. Among the frontrunners will be cars running on compressed natural gas, electric vehicles, propane-powered cars, vehicles running on gasoline-ethanol combinations, hydrogen vehicles, and all manner of hybrid combinations of any of the above Obama’s order built on a previous executive action in 2009 that has helped reduce greenhouse-gas emissions by 17 percent. The 40 percent reduction will be measured against levels in 2008, right before Obama took office.

As of 2013, more than 200,000 of the federal fleet of 635,748 vehicles were alternative-fuel vehicles. The most common of these were the 180,000 cars running on an ethanol-gasoline mix. But the new cars are expected to be of the more experimental variety. It is anticipated that, by 2025, half the federal vehicles will be some kind of plug-in hybrid.

The White House pointed to the efforts of large private companies such as IBM, GE, Honeywell and Walmart in meeting the same standards of switching to alternative vehicles in their fleet. The president’s spokespeople said the combined effort would be “the equivalent of taking nearly 5.5 million cars off the road.”

The president’s order was not the only effort by the federal government to increase its fleet of alternative vehicles. The Department of Energy announced a $6 million program to accelerate the alternative vehicle market. DOE said the purpose of the grants will be to get people accustomed to the idea of driving alternative vehicles. Eleven projects will be funded around the country. They will include:

  • Clean Fuels Ohio will sponsor the Midwest DRIVES initiative to make alternative fuel vehicles available to select company fleets on a short-term lease basis. The program will used data collected from these experiments to encourage other companies to lease AFVs as well.
  • Penske Truck Leasing of Reading, Pennsylvania, will make compressed natural gas heavy-duty trucks available to cross-country truck fleets on a 1-to-3-month basis. The object will be to test consumer satisfaction.
  • The Florida Office of Consumer Services, Office of Energy, will make available plug-in hybrid vehicles to car rental companies in the Orlando area. With Disney World at its doorstep, Orlando is the nation’s largest car-rental market. The idea will be to accustom renters to the advantages of plug-in hybrids.
  • The Triangle Council of Governments around Research Triangle Park will supply vehicles powered by CNG, electricity, propane, E85 and biodiesel over a three-state area that will include North Carolina, South Carolina and Tennessee. The object will be to encourage fleet purchases.
  • The Plug-In Hybrid Electric Vehicle Demonstration Program, run by ASG Renaissance of Dearborn, Michigan, will attempt to stimulate consumer awareness and demand for PHEVs by placing them in the hands of media influencers. It is hoped that a social media campaign through Facebook and Twitter will bring positive coverage.
  • The West Virginia University Research Corporation will develop a curriculum for training promoters and repair specialists for alternative vehicles. The National Alternatives Fuels Training Consortium will provide marketing and outreach for the new curriculum.
  • The National Fire Protection Association of Quincy, Massachusetts, will develop curricula for the use of alternative vehicles in fire protection, emergency services and first responders to auto accidents.
  • The North Central Texas Council of Governments will develop a curriculum for use of propane, electric and natural gas vehicles for fire marshals, code officials, mechanics and technicians, and first responders. The program will be offered in four states of the Southwest.
  • The University of Central Florida will establish a training program for the use of CNG, electric and propane vehicles by first responders, college instructors, tow-truck operators and salvage/recycling vehicles. Hands-on training will be supported by vehicles supplied the National Association of Fleet Managers.
  • The Metropolitan Energy Center of Kansas City will collaborate with State Fire & Rescue Training institutes in Kansas and Missouri to adapt existing alternative fuel safety curricula to their existing training structures.
  • The National Association of State Energy Officials will work with its network of State Energy Offices, the National Governors Association, and the International Emergency Managers Association to help incorporate alternative fuel and advanced vehicles into multiple emergency preparedness plans.

So there’s plenty going on in the advance of alternative vehicles. It will take more than a drop in the price of oil to discourage these programs.

New Tool Advances Genetic Engineering of Fuel Crops

A powerful new tool that can help advance the genetic engineering of “fuel” crops for clean, green and renewable bioenergy, has been developed by researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Lawrence Berkeley National Laboratory (Berkeley Lab).


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.

Is Elon Musk the next Henry Ford?

Elon Musk doesn’t mind making comparisons between himself and Henry Ford. Others are doing it as well.

In announcing his plans for a “Gigafactory” to manufacture batteries for a fleet of 500,000 Teslas, Musk said it would be like Ford opening his famous River Rouge plant, the move that signaled the birth of mass production.

The founder of PayPal and current titular leader of Silicon Valley (now that Steve Jobs is gone), Musk is not one for small measures. The factory he is now dangling before four western states would produce more lithium-ion batteries than are now being produced in the entire world. And that’s not all. He’s designing his new operation to mesh with another cutting-edge, non-fossil-fuel energy technology – solar storage. His partner will be SolarCity (where Musk sits on the board), run by his cousin Lyndon Rive. Together they are looking beyond mere automobile propulsion and are envisioning a world where all this solar and wind energy stuff comes true.

So, is Musk a modern-day Prometheus, bringing the fire to propel an entirely new transportation system? Or, as many critics charge, is he just conning investors onto a leaky vessel that is eventually going to crash upon the shores of reality? As the saying goes, we report, you decide.

One investor that is already showing some qualms is Panasonic, which already supplies Tesla with all its batteries and would presumably help the company fill the gap between the $2 billion it just raised from a convertible-bond offering and the $5 billion needed to build the plant. “Our approach is to make investments step by step,” Panasonic President Kazuhiro Tsuga told reporters at a briefing in Tokyo last week. “Elon plans to produce more affordable models besides [the] Model S, and I understand his thinking and would like to cooperate as much as we can. But the investment risk is definitely larger.” Of course, this is Japan, where “the nail that sticks out gets hammered down.” Corporate executives are not known for sticking their necks out.

Another possible investor is Apple, which has mountains of cash and, at least under Steve Jobs, was always willing to jump into some new field – music, cell phones – to try to set it straight. This is a little more ambitious than the Lisa or the iPod and Jobs is no longer around to steer the ship, but Apple and Musk officials held a meeting last spring that stirred a lot of talk about a possible merger. A much more likely scenario, according to several commentators, is that Apple would become a major player in the Gigafactory.

And a Gigafactory it will be. Consider this. The three largest battery factories in the country right now are:

1)    The LG Chem factory in Holland, Mich. is 600,000 square feet, employs 125 people and produces 1 gigawatt hour (GWH) of battery output per year.

2)    The Nissan factory in Smyrna, Tenn. is a 475,000 square-foot facility with 300 employees puts out 4.8 GWH per year.

3)    A123 Systems’ battery factory in Livonia, Mich. is 291,000 square feet, employs 400 people and produces 0.6 GWH per year.

Both LG and Nissan received stimulus grants from the Department of Energy, built to overcapacity and are now operating part-time.

Now here’s what Musk is proposing. His Gigafactory would cover 10 million square feet, employ 6,500 people and produce 35 GWH per year of battery power. Basically, Musk’s operation is going to be ten times better anything ever built before, at a time that most of what exists isn’t even running fulltime. Does that sound like something of Henry-Ford proportions? Similar to Ford’s $5 a day wages, perhaps?

There are, of course, people who think all of this is crazy. In the Wall Street Journal blog, “Will Tesla’s $5 Billion Gigafactory Make a Battery Nobody Else Wants?,” columnist Mike Ramsey expresses skepticism over whether Tesla’s strategy of using larger numbers of smaller lithium-ion is the right approach. “Every other carmaker is using far fewer, much larger batteries,” he wrote. “Tesla’s methodology – incorrectly derided in its early days as simply using laptop batteries — has allowed it to get consumer electronics prices for batteries while companies like General Motors Co. and Nissan Motor Co. work to drive down costs without the full benefits of scale. Despite this ability to lower costs, no other company is following Tesla’s lead. Indeed, in speaking with numerous battery experts at the International Battery Seminar and Exhibit in Ft. Lauderdale a few weeks ago, they said that the larger cells would eventually prove to be as cost effective, and have better safety and durability. This offers a reason why other automakers haven’t gone down the same path.

But Musk has managed to produce a car that has a range of 200 miles, while the Leaf has a range of 85 miles and the Chevy Spark barely makes 82. Musk must be doing something right. And with Texas, Arizona, Nevada and New Mexico all vying to be the site of the Gigafactory, it’s more than likely that the winning state will be kicking in something as well. So, the factory seems likely to get built, even on the scheduled 2017 rollout that Tesla has projected.

At that point, Musk will have the capacity to produce batteries to go in 500,000 editions of the Tesla Model E, which he says will sell for $35,000. Sales of the $100,000 Model S were 22,000 last year. Does this guy think big or what?

To date, Silicon Valley doesn’t have a terribly good record on energy projects. Since Kleiner Perkins Caufield & Byers fell under Al Gore’s spell in 2006, its earnings have been virtually flat and the firm is now edging away from solar and wind investments. Venture capitalist Vinod Khosla’s spotty record in renewables was also the subject of a recent 60 Minutes segment. But, as venture capitalists say, it only takes one big success to make up for all the failures.

Will Tesla’s Model E be the revolutionary technology that, at last, starts making a dent in oil’s grip on the transportation sector? At least one investor has faith. “I’d rather leave all my money to Elon Musk that give it to charity,” was the recent evaluation of multi-billionaire Google founder Larry Page.

The oil industry and API, at it again. When will they ever learn?

Never a dull moment! The API is at it again. Just a few days ago, it dramatically issued a survey indicating that close to 70% of all consumers were worried that E15 (a blend of 15% ethanol and 85% gasoline) would damage their cars. While the survey was done apparently by a reputable firm, it was not attached to the press release, preventing independent experts or advocate group experts from commenting or verifying the questions and the sample. More importantly, the survey was preceded by an expensive oil industry media blitz that illustrated or talked about the so-called evils of ethanol. The survey and media show reflected an attempt by the oil industry to eliminate or weaken the renewable fuel mandates and lessen competition from alternative transitional fuels.

Americans are usually not Pavlovian in demeanor or behavior; we do ask for second and even third opinions from our doctors. But when only one group, in this case, the oil industry, has put out a continuous flashy very expensive multimedia message, the API’s survey results were almost preordained to reflect the published results. Whatever the industry wanted it got! If you tell a misleading partial story to create fear and uncertainty, long enough, it will likely influence many. In this case, the API, if it had a nose, its nose, similar to Pinocchio’s, would be growing and growing and growing.

Let’s look at the facts — never acknowledged by the API in its “Fuel for Thought” campaign.

  1. DOE effectively demolished the API-supported study many months ago indicating that the sampling approach was wrong and the analysis was faulty. DOE’s study used a much larger number of vehicles and was far more rigorous concerning methodology. (Just to let you know, API is an oil industry funded group.)
  2. Many countries around the world have used E15 and higher ethanol blends as a fuel without significant problems. They are seen as a way to reduce environmental problems. They are cheaper than gasoline and they reduce the need, at times, for oil imports. Put another way, they improve quality of life, lower costs to the consumer, and are good for the economy and security.
  3. Although oil company franchise agreements with gas stations have limited the number of stations able to sell E15, several states (mostly in the Midwest) with multi-fuel stations, have demonstrated the merits of E15. Early data appears to discount engine problems.

Hell, Henry Ford’s initial car was designed to run on pure ethanol until the temperance movement supported by Standard Oil banned the use of manufactured alcohol. I know Standard Oil was very concerned that Americans would drink ethanol at their favorite bars or in front of their favorite fire place with their favorite significant other. Praise be to Standard Oil for salvation!

The law (RFS) requires a 10% ethanol blend with gasoline. More than a year ago, EPA OK’d the sale of E15 (for most cars particularly those produced after 2001). In June, the Supreme Court refused to hear the appeal by the oil industry of EPA’s standards.

API’s media campaign raises the food versus fuel fight canard because ethanol is produced mostly from corn as the feedstock. But the narratives neglect to raise the fact that the evidence concerning the negative impact on food is disputed by reputable analysts who indicate that, for the most part, the corn used for ethanol production is not your friendly grocery counter corn. Put another way, most of the corn to ethanol conversion comes from corn not able to be used for food. Yes, there still maybe some impacts on corn production and prices because of the growers reallocation of land, in light of the differential between corn and ethanol prices, to ethanol. However, many studies suggest that if a negative food impact exists, it is relatively minor. It is a worthy debate.

It appears, that API, conveniently, forgets to mention that ethanol can be produced efficiently and effectively from natural gas and that cellulosic based ethanol is now being manufactured or will soon be manufactured in large volumes by several companies. Further, Clean Energy Fuels announced this week that it will start selling fuel made from methane in landfills and other waste sources in over 40 stations in California. Success of these initiatives, likely, will mean the end of the fuel versus food issue. If success is combined with the inexpensive conversion of existing cars to flex fuel cars permitting them to use alternative fuels, America will be blessed with a much cleaner, environmentally safe, and cheaper alternatives to gasoline- assuming the oil industry doesn’t block their sale at fuel stations.

Clearly, the oil industry does not want competition at the pump from ethanol…whether corn, cellulosic, garbage or natural gas. The American public should be wary of misleading guerilla marketing through industry funded surveys or not so benign expensive media blasts by captive organizations like API. Hopefully, the American consumer will not be confused for long. Paraphrasing a song by Peter, Paul and Mary about war and peace and a statement by President Lincoln, when will the oil companies ever learn?, and, if they don’t learn, when will they recognize “they can fool all the people some of the time and some of the people all the time but they cannot fool all the people all the time.”
