In Late June the Department of Commerce determined that two Texas companes could start exporting an ultralight type of crude called condensate. This constitutes the bigget loosening of the U.S. ban on oil exports since 1975.
Researchers at the University of California, Riverside, have come up with a magic ingredient that may improve the performance of lithium-ion batteries by a factor of three. It’s common beach sand.
“The optimist proclaims that we live in the best of all possible worlds and the pessimist fears this is true” — James Branch Cabell. Or, as I once said in a presentation in China after Tiananmen Square, “a strategic optimist is a realist with brains.”
I live with the hope we can do better as nation with respect to the environment, our economy and the quality of life choices open to Americans, particularly low- and moderate-income Americans. But I worry that given the ideological and related political divisiveness among us, we may not.
In this context, after reading the recent article, “SAFE: Report’s ‘flash points’ emphasize US transportation fuel problem” in the Oil & Gas Journal, often seen by some as a mouthpiece for the oil industry, my thoughts reflected both optimism and pessimism. I concluded that I was a realist tempered by experience (and hopefully with a brain). Okay, what did the piece suggest that stimulated my mental and emotional adrenaline? Two or three quotes used by the author Nick Snow, respected Washington editor of OGJ, taken from a national conference convened by Securing America’s Future Energy (SAFE):
“A proliferation of global oil geopolitical ‘flash points’ (e.g., conflicts in countries or within countries that limit or could limit the supply of oil) makes it even more urgent for the U.S. to aggressively reduce its dependence on crude oil for transportation fuels…If we could be only 65% dependent on oil for our transportation fuels by 2025 instead of 90%, it would make a tremendous difference…We also need better politics developed by people who can find win-win situations so we can move forward…We all agree that we need to diversify our transportation sources away from oil.”
Nick Snow is no blazing liberal. According to his resume, Mr. Snow has spent 30 years or so as a journalist covering oil issues, many of those for media outlets friendly to oil interests (e.g., Oil Daily).
Have we reached nirvana? Did the article in the OGJ signal that big or small oil companies will soon announce their commitment to replacement fuels, like natural gas-based ethanol and methanol? Their support, given the fact that some oil companies already own significant natural gas fields, could be important from a public policy and an “on the ground production and distribution” perspective.
When I was a kid, older members of my family, if they wanted something but knew it was impossible to secure, would say, “I should live so long.” In some respects, while I’m surprised by the selected quotes used in the article by Mr. Snow, I doubt it heralds an epiphany by leaders of the oil industry or their companies.
Why am I a wannabe optimist but a realistic pessimist? Oil companies’ primary behavior over the past decade or more has been to oppose the development of most replacement fuels, FFVs and open fuel markets. Sometimes they have done this through other organizations that they influence or control, and sometimes directly. Clearly, gas station franchises granted by oil companies remain tied to a “just say no” position on replacement fuels, or a back- or side-of-the-station mandate concerning location of replacement-fuel pumps. For the most part, their reaction to “flash points” has been “drill, baby, drill,” and their battle cry has been that only more drilling will make the nation oil independent. This is a curious stance, since companies are simultaneously seeking to increase their ability to export globally. America still imports about a third of its oil, while retail prices for gasoline at most stations remain high.
I’m afraid that the OGJ piece by Snow is not a harbinger of good tidings concerning oil company endorsement of replacement fuels — at least any time soon. Rather, the article reflects a willingness of the author to honestly describe a major issue facing the nation, that is, the disproportionate share of oil in transportation fuels. Regrettably, excluded from the piece is a narrative about the fact that oil converted to gasoline has a significant negative effect on the environment, and that oil imports still take a toll on the economy. Replacement fuels would address security, environmental and economic issues, and related national objectives in a much more positive way.
I have a vested interest in remembering the famous Andrews Sisters. How many of you remember them? They played in my uncle’s band for a short time. So let me end, somewhat inappropriately, using the last stanza of one of their hit tunes “I Can Dream, Can’t I?” by composer Sammy Fain. I am sure neither the sisters nor Sammy would mind. With respect to the oil companies, “I am aware. My heart is a sad affair. There is much disillusion there. But I can dream, can’t I?”
Dreaming is about all you can do now, with respect to getting oil companies to develop, or support the development of, flexible replacement fuels. Maybe someday!
The headlines recently have been terrible — a commercial plane was shot down over the Ukraine, there’s war in the Middle East and more. It makes you wonder, over and over again, about man and woman’s inhumanity to his or her fellow men and women.
While certainly not equal in impact on the world at the present time, I happened to run across one point of light concerning a set of innovations which, in the long run, could positively impact climate change, security and consumer choice issues. It was reflected in a couple of articles describing the partnership between the state of California’s Energy Commission and Cummins Engines to develop an E85-fueled engine that apparently cuts Co2 by up to 80 percent (read it in Fleets and Fuels) in medium-duty trucks.
According to Cummins Engines and the Commission, a relatively small 4-cylinder, 2.8-liter engine has been successfully subjected to 1,000 miles and 1,500 hours of testing. It is now going through validation tests in Sacramento.
The story is a welcome one. Cummins indicates that the engine can generate 250 horsepower and 450 pound-foot of torque using E85. “Using lignocellulosic-derived E85, the powertrain’s efficiency features 75 to 80 percent lower well-to-wheels carbon emissions than gas engines; depending on the drive cycle…Cellulosic E85 is not derived from tilling, fertilizing and harvesting corn…Using corn-derived E85, the high thermal efficiency and power-to-weight ratio of this engine results in 50 to 80 percent lower well-to-wheels carbon emissions compared with the gasoline engine.”
Based on the Cummins documentation, California’s Energy Commission indicates “that successful completion of the project may result in a new market for E85 fuel now dominated by gasoline and diesel in the 19,500 lb. step-van fleet market.” The agency estimates greenhouse-gas savings as great as 69 percent, or 10 to 20 percent using corn based ethanol.
Fortunately, the general principles guiding development of Cummins’ engine may help improve flex-fuel automobiles and grant Americans more confidence in the environmental, price and economic benefits associated with extended use of E85.
Lessons learned may increase the nation’s ability to reduce GHG emissions. Based on what Cummins has done, using smaller engines extends the benefit of E85. Diesel-like cylinder pressures are important. Ethanol’s high-octane rating generates more engine efficiency. Use of state-of-the art sensors for spark ignition and coordination of stop-and-start functions enhances efficiency and reduces emissions. E85 is clearly a safe fuel.
The knowledge gained from the Cummins effort could lead to better flex-fuel vehicles and could support the effort to use increased technology fixes for older, non-flex-fuel cars and FFV twins. Perhaps the biggest benefit from the partnership between California and Cummings relates to the boost it could give to the search for replacement fuels, as well as the myth-busting understanding it could provide consumers about the safety of E85. It is a safe fuel, assuming engine adaptation and software amendment.
Elon Musk’s proposal to share Tesla’s electric-car patents and ideas might at least encourage increased collaboration among FFV makers in Detroit and the potential players in the conversion industry that likely would emerge, subsequent to EPA testing and approval of older vehicles for conversion. Even improved cooperation at the margin would could expand production of new FFV vehicles and expand conversion of older vehicles. For automakers and makers of conversion kits, as well as developers of FFV software technology, successful collaboration would generate larger markets.
Increased use of E85 through conversion of existing cars and the increased production of new FFV vehicles would help meet national and local environmental objectives, reduce gasoline prices and provide consumers with lower fuel costs, apart from gasoline. Both would also reduce dependency on foreign oil. Paraphrasing the poet Robert Frost, while FFVs — new or converted — are on a road less traveled now, as John F. Kennedy indicated, the journey of a thousand miles must begin with one step. The road less traveled now has more replacement-fuel drivers and FFVs than ever. Because of this fact, the journey of a thousand miles toward alternative fuel choices has made progress and, hopefully soon, will move at a faster speed. Success will mean a better quality of life for us all. It’s good news!

One of the greatest appeals of switching to an alternative-fuel vehicle — electric, compressed natural gas or hydrogen — is saving money and freeing yourself from the clutches of foreign oil. But another is being able to supply your own fuel from a garage filling station where you may even be able to generate some of it yourself.
All this takes on a certain air of necessity when you realize that most of the infrastructure for recharging or refilling is not yet in place. In many cases, the garage may be the best option right now. So let’s run down some of the different options available and see how they stack up as being economical and practical.
Let’s start with the easiest one — electric cars. There are three types of chargers available to owners of a Prius, Leaf or Chevy Volt. The first is a Level 1 “trickle” charger, which is just a basic 120-volt line that plugs into any three-pronged outlet. This is the standard plug-in for all EVs. The problem is the amount of time it takes for a complete charge. For the Leaf, it takes close to 21 hours, which means that you can’t even do it overnight. For hybrids there’s some leeway since you can always revert to the gas motor and do some brake recharging as well. But if you’re planning to rely completely on a home outlet, you’d better have a second car.
More favorable is a Level 2 240-volt circuit. If you have an electric clothes dryer in your house, you’re already equipped. If you don’t have a 240-volt system at home, installation is easy enough. It will require a 40-amp circuit breaker, which may need a permit from the local building department, but the job is simple enough. Recharging time will be cut to less than eight hours, enough for an overnight. Plugincars.com puts the price at $600 -$700, although vendors such as ClipperCreek lists some for less.
If you really want to go really high-tech, you can move up to a Level 3 480-volt power supply that can give you an 80 percent charge in half an hour. The whole package costs $30,000, but with federal tax breaks and some help from the car companies, you can get it down to $10,000. Nissan offers a unit for $9,900. You could probably recoup some of the costs by recharging EVs for your neighbors, but you might need a zoning variance.
So how about compressed natural gas? What are the options there?
The Honda Civic is the only CNG passenger vehicle being sold in the United States. (Most of the progress has been with delivery trucks and long-haul trailers.) There are currently 1,000 CNG filling stations across the country, but half of them belong to companies that are using them for their fleets. Only about 500 are available to the public. So, unless you’re traveling along an Interstate and can make it to one of Clean Energy Fuels’ new truck stops, you’re going to have a hard time.
Refilling at home, however, isn’t all that impractical. More than half the residences in the country are equipped with natural gas for home heating, cooking or hot water. The trick is to get a device that can compress this household gas to be used in your car.
Honda originally offered a home refueling kit, the Phill, which costs $4,500 and could do a refill overnight. Honda stopped making the offer after 2012; however, due to concerns about the widely varying quality of non-commercial gas and the possibility of home devices allowing moisture to collect in the fuel system. For those willing to take the chance, the Phill is still available from its manufacturer, BRC FuelMaker. The question is, “Why is it so expensive when the same pump would cost 10% if it filled air bottles?” There is a regulatory review needed to reduce the cost.
Seeking to promote the technology, the Department of Energy (DoE) handed out grants a few years ago to encourage companies to develop affordable home systems. Now one of them may have come through. The Eaton Corporation of Cleveland, already prominent in the field of electrical charging stations, announced in 2012 that it plans to market a CNG home refueling device by 2015. “The system will use liquid to act as a piston in compressing the gas,” says Chris Roche, vice president at Eaton’s Innovation Center. “We have also developed an innovative heat exchange technology that will improve efficiency and cut costs dramatically.” Eaton is aiming at production costs of $500, which means the device could sell for less than $1,000. GoNatural, a Salt Lake City company, has also promised to have a product available by 2015. “It could be a game changer,” said New York Times reporter Paul Stenquist, in profiling CNG home compressors last October.
So, what about hydrogen? Is there anything available there? Hydrogen is very difficult to deal with. It is the smallest atom and will leak through just about anything. It’s hard to store and transport and must be kept under high pressure.
The upside, however, is the possibility of generating your own hydrogen, particularly from renewable resources. This can be done with simple electrolysis of water, which only requires an electric current. If you can generate that current with wind or solar energy, then you are essentially powering your car for free.
Making it happen is probably a long way off, although people are working on it. HyperSolar, Inc., a Santa Barbara company, has announced “proof of concept” of a method for generating solar hydrogen. “Using our self-contained particle in a low cost plastic bag, we have successfully demonstrated our ability to mimic photosynthesis to produce renewable hydrogen from virtually any source of water using the power of the Sun,” said CEO Tim Young while making the announcement. Horizon Fuel Cells, a Singapore company, released a “desktop” hydrogen generator in 2010 that generates hydrogen through electrolysis from any power source. It sells for $250 on Amazon. Although the company is targeting much smaller fuel-cell devices, it could eventually scale up to handle quantities needed to run a hydrogen fuel cell car
Altogether for cutting loose from the local gas station, electric vehicles are the best bet for now. But natural gas in its many forms — including methanol — are moving up and renewable hydrogen may be on the horizon. With home-generating devices proliferating, it is not hard to see all this eventually making a dent in our consumption of fossil fuels.

PUMP, the latest documentary feature film from Joshua Tickell and Rebecca Harrell Tickell, will be making its long awaited premiere this September in specially selected theaters around the country.
According to its makers, the documentary “tells the story of America’s addiction to oil, from its corporate conspiracy beginnings to its current monopoly today, and explains clearly and simply how we can end it – and finally win choice at the pump…”
