Paul Harvey, the rest of the news and natural gas

Paul Harvey was a conservative icon in radio news during the mid to end of the 20th century. While I often differed with the substance of his commentary, he was a welcome travel partner when driving, particularly on a long trip. What I liked most about him was that he generally articulated his views without being malicious, and his voice was just wonderful. He sounded like a symphonic rap musician, using iambic pentameter.

One of Harvey’s favorite phrases was here’s “the rest of the story.” Remembering it, gives me a wonderful opening for this column.

This week there were several optimistic articles on natural gas growth this past week . One article in particular caught my eye. The piece described the expanded, but still relatively low, market penetration of natural gas as a transportation fuel. Given the cost and environmental benefits of natural gas, I was pleased to read the content and see the numbers and quotations. But in Paul Harvey’s terms it did not tell “the rest of the story”!

Yes, natural gas is making inroads into the trucking industry, even among buyers of new cars, asserts the article. “The boom in natural gas production in the U.S. has ignited a revolution in the auto sector that could reshape the way Americans fuel their vehicles, market participants and analysts said in a week-long special on FOX Business.” ClearView Energy Partners, the Newport Beach, California company that is building fuel stations along major interstate trucking corridors, will likely facilitate the growth of natural gas as a fuel in trucks. It will provide one of the missing pieces that have impeded natural gas’ popularity — fear of running out of fuel. “About 25% of the truck market could convert to natural gas by 2020, according to a report by Citigroup…eight in 10 new trucks Waste Management brought in 2012 were powered by natural gas.” Your friendly bus driver’s bus is increasingly likely to run on natural gas.

“Only a tenth of a percent of natural gas consumed in U.S. last year was used for fuel in vehicles, according to the Energy Department. Of the more than 15.2 million natural gas vehicles on roads across the globe, [only] about 120,000 are in the U.S.” Natural gas clearly hasn’t taken off yet as a transportation fuel in the U.S. Kevin Book, ClearView’s managing director of research indicates that, “I think you look at locomotives, also a very interesting and potentially large market, and also some of the marine applications before you start talking about smaller passenger cars.” I suspect his negative perceptions of natural gas as a competitive fuel in cars stems from the present costs of CNG passenger vehicles and the present absence of CNG fuel stations — a possible temporary problem if ClearView’s commitment to develop a natural gas highway could extend to private automobiles. We have had many successful freedom movements in this country. There would be only relatively marginal costs to extend the capacity of the natural gas highway’s fuel stations to include CNG availability for all consumers of natural gas vehicles and to assure availability of natural gas derivative fuels like ethanol. If you build it, many of the 17 million FFVs now on the road will come and more will follow, given what’s presently on the (near term) horizon.

Here is more of “the rest of the story,” à la Paul Harvey. One of the most innovative programs to stimulate the use of natural gas, CNG, was initiated by Gov. Hickenlooper and Gov. Fallin. Under their nonpartisan umbrella, 22 states have agreed to replace older cars, when they are due to retire, with CNG cars. Their commitment will create a large pool of CNG purchases over the next few years. Detroit has agreed to work with the states and both the governors and carmakers want to use the effort to produce a less expensive CNG car for American households.

But there is more! Two companies, Coskata, Inc. and Celanese have had success in converting natural gas to ethanol and are both striving to commercialize and define strategies to market their product. If they are successful, other companies will follow in light of historical “copycat capitalism.” The result will be a fuel that will be environmentally better and clearly cheaper than gasoline. The result will also be increased demand for fuels like E85, which will generate consumer purchases of FFVs and the conversion of existing, older cars. It may also open up the pockets of investors concerning the support for future E85 pumps. If ethanol becomes popular because of price and environmental objectives, can methanol be far behind (excuse me, Percy)? Freedom to choose what you drive and what fuel you use on the high and bi ways of this nation would be consistent with the American way and creed.

Madera Pacific Ethanol plant lands sweet neighbor

It’s better times for California’s ethanol producers, with investment dollars flowing into technology to make production plants more efficient and diverse in the feedstocks they accept.

“We are just about there,” said Paul Koehler, spokesman for Sacramento-based Pacific Ethanol, referring to the long-time effort to begin making ethanol from farm waste and nonfood feedstock instead of corn

Study: Ethanol co-product may offer low-fat product for use in swine diet

Distillers dried grains with solubles (DDGS) are a co-product of the ethanol industry and have been an affordable source of energy and protein in swine diets for decades. In recent years, ethanol plants have begun to centrifuge the solubles from ethanol production to extract oil, which is sold to the biodiesel industry.

 

Toyota Embraces Hydrogen

Toyota is the world’s most successful car company. The Prius is the most popular gas-electric hybrid ever, with 3 million sold in 80 countries worldwide. Toyota can be said to have pioneered the first vehicle that has challenged the traditional internal combustion engine.
So why is the Japanese giant now moving away from hybrids and placing its bets on the hydrogen fuel cell?
It’s a tough question. Not many analysts can see the sense of it. Elon Musk dismisses the whole idea as “fool cells” and says it can’t succeed. Yet, Toyota maintains that there are inherent advantages in the technology that will eventually emerge. Most of all, the decision by Toyota, Honda and Hyundai to go with hydrogen instead of electric vehicles has set off a fierce debate on which technology — if either — represents the better route to replacing the internal combustion engine.
It is not as if this is a snap decision for Toyota. In 1992, the company set up two task forces — one to investigate the gas-electric hybrid and one to pursue the hydrogen vehicle. In 1997 the Japanese giant introduced the Prius, which has gone on to become one of the most successful models of all time. But work never stopped on the fuel cell project. Now, as company officials reportedly believe hybrid technology may have reached the point of diminishing returns, they feel it is time to move on to something new. “Of all the advanced power train systems we have in our portfolio,” Toyota Senior Vice President Bob Carter told Green Car Reports, “we see hydrogen fuel cells as being the no-compromise, primary-option vehicle for the next 100 years.”
All this is happening, of course, at the moment when Tesla seems to be proving that electric vehicles can go head-to-head with gas-powered cars. So the question is, what does Toyota see in hydrogen that can’t be achieved by following up with electrics?
Range is one answer. Toyota is still convinced that electric vehicles will never get beyond the 150-200-mile range that most EVs now achieve — although Tesla is already pushing toward 300. The new Toyota Fuel Cell Vehicle (FCV) that will go on sale in California next summer will have a range of 300 miles, with hopes of future improvement.
Even more important than range is refueling time. A fuel-cell vehicle can fill up at a hydrogen pump in ten minutes — still significantly longer than gasoline — but an EV takes from four to six hours. Even the new “superchargers” that Musk is installing around the country take 20 minutes to give a half-charge. But Musk is also working on a battery-pack replacement that would be faster than a gasoline fill-up.
Of course all this is predicated on having “filling stations” available, and on that score, hydrogen is even further behind. There are only 60 such facilities in the entire country. Tesla just announced its 100th supercharging station in April and that’s just a small part of the action. Most EV owners recharge at home and the electric grid is everywhere. Providing hydrogen around the country would require a whole new infrastructure.
Joseph Romm, who once promoted hydrogen cars as Assistant Secretary of Energy under Bill Clinton and later wrote the book, “The Hype About Hydrogen,” remains one of the fiercest critics of the technology. “Hydrogen is the smallest molecule and escapes almost any container,” he wrote in his blog, ThinkProgress. “It makes metals brittle. It is almost impossible to transport. These are physical barriers that will be very difficult to overcome.”
Another surprising aspect of hydrogen is that it is not particularly cheap. Unlike EVs, ethanol or methanol made from natural gas, hydrogen does not offer consumers any financial incentive. At the J.P. Morgan Auto Conference in New York last week, Senior Vice President Carter admitted that a full tank of hydrogen needed to carry the driver 300 miles will cost $50, slightly higher than ordinary gasoline. By contrast, the owner of a Prius only pays $21 for the same trip, and the owner of a Tesla Model S would pay $9.60 at off-peak rates. It’s hard to see how there is going to be any appeal to consumers.
Now it must be admitted that much of the fierce debate taking place on the Internet concerning fuel cells vs. EVs revolves around reducing carbon emissions rather than freeing ourselves from foreign oil. EV advocates imagine a grid running on wind and solar energy while H2 partisans envision windmills and solar collectors turning out prodigious amounts of hydrogen. Other environmental critics have argued that without a larger component of non-fossil-fuel sources generating the electricity, converting to electric vehicles will do nothing to reduce carbon emissions, although some people disagree with all this.
It sometimes seems as if we are trying to accomplish too many things at once. Putting more FCVs and EVs on the road would definitely move us toward energy independence. The source of the hydrogen or electricity can be sorted out later, and the same goes for methanol and ethanol as a liquid substitute for gasoline. These fuels might originally come from natural gas, but renewable sources such as landfill gas and manure piles could be substituted later.
The important thing is to keep moving forward on all fronts. No one knows when some vast new battery improvement or an entirely different method of extracting hydrogen may prove to be a game-changer. Toyota is doing this by pursuing the fuel cell vehicle — even though for the present the odds seem slightly stacked against it.

Fuel Fight: Corn Waste Wades Into Renewables Fracas

There may be no romance in its seven-syllable name, yet for corn growers and environmental advocates, corn-based cellulosic ethanol holds the promise of an elixir. Cellulosic ethanol is a fuel made not from corn kernels, but instead the husk, stalk, cob and other waste parts of corn. And after being broken down by yeast and enzymes, proponents say it burns more cleanly than regular ethanol made from the parts of corn we’d otherwise eat.
