Fake and real news: Links between GHG reduction and alternative fuels

/in , , , , , /by

FT-emissions-graphicTurn on your local news every night and you’ll need a sleeping pill to get some rest. The format and content is the same around the country: a lot of tragic crime — ranging from sexual harassment, robbery and shootings — for about ten minutes; local sports for about 5 minutes; what seems like ten minutes of intermittent advertising; silly banter between two or more anchors for two minutes; and a human-interest story to supposedly lighten up your day at the very end of the show — likely about a dog and cat who have learned to dance together or a two-year-old child who already knows how to play Mozart. You get the picture!

Local news, as presently structured, is not about to send you to sleep feeling good about humanity, never mind your community or nation. National news is really only marginally better. Again, the first ten minutes, more often than not, are about environmental disasters in the nation or the world — hurricanes, volcanoes, cyclones and tornadoes. The second ten minutes includes maybe one or two tragically laced stories, more often than not, about fleeing refugees, suicide bombings, dope and dopes and conflict. Finally, at the end of the program, for less than a minute or two, there is generally a positive portrayal of a 95-year-old marathon runner or a self-made millionaire who is now single-handedly funding vaccinations for kids in Transylvania after inventing a three-wheeled car that will never need refueling and can seat twenty-five people.

Maybe this is how the world is! We certainly need to think about the problems and dangers faced by our communities, the nation and its citizens. Every now and then, Americans complain about the media’s emphasis on bad news. But their complaints are rarely recorded precisely in surveys of viewership. We criticize the primary emphasis on bad news, but seem to watch it more than good news. Somewhat like football, we know it causes emotional and physical injuries to players, but support it with the highest TV ratings and attendance numbers.

Jimmy Fallon, responding to the visible (but likely surface) cry for more good news, has added a section to The Tonight Show. He delivers fake, humorous news, which is, at times, an antidote to typical TV or cable news shows. Perhaps John Oliver, a rising comedian on HBO, does it even better. He takes real, serious news about human and institutional behavior that hurts the commonweal and makes us laugh. In the process, we gain insight.

This week’s news about carbon dioxide emissions “stalling” in 2014 for the first time in 40 years appeared in most newspapers (I am a newspaper junkie) led by The New York Times and the Financial Times. It seemed like good news! Heck, while the numbers don’t reflect a decline in carbon emissions, neither do they illustrate an increase. Let’s be thankful for what we got over a two-year period (in the words of scientists — stability, or 32.3bn tons a year).

But don’t submit the carbon stability numbers to Jimmy Fallon just yet. It’s much too early for a proposed new segment on The Tonight Show called “Real as Opposed to Fake, Good News.” Too much hype could convince supporters of efforts to slow down climate change that real progress is being made. We don’t know yet. Recent numbers only reflect no carbon growth from the previous year over a 12-month period. The numbers might be only temporary. They shouldnt lessen the pressure to define a meaningful fair and efficient strategy to lower GHG. If this occurs, yesterday’s good news will become a real policy and environmental problem for the U.S. and the world for many, many tomorrows.

I am concerned that the stability shown in the carbon figures may be related to factors that might be short lived. Economists and the media have attributed the 2014 plateau to decreases in the rate of growth of China’s energy consumption and new government policies, as well as regulations on economic growth in many nations (e.g., requirements for more energy-efficient buildings and the production of more fuel-efficient vehicles), the growth of the renewable energy sector and a shift to natural gas by utilities.

Truth be told, no one appears to have completed a solid factor analysis just yet. We don’t really know whether what occurred is the beginning of a continuous GHG emission slowdown and a possible important annual decrease.

Many expert commentators hailed the IEA’s finding, including its soon-to-be new director, Dr. Fatih Birol. He indicated that this is “a very welcome surprise…for the first time, greenhouse gas emissions are decoupling from economic growth.”

Yet, most expert commentators suggest we should be careful. They noted that the data, while positive, is insufficient to put all our money on a bet concerning future trends. For example, Hal Harvey, head of Energy Innovation, indicated, “one year does not a trend make.”

Many articles responding to the publication of the “carbon stall” story, either implicitly or explicitly, suggested that to sustain stability and move toward a significant downward trend requires a national, comprehensive strategy that includes the transportation sector. It accounts for approximately 17 percent of all emissions, probably higher, since other categories such as energy use, agriculture and land use have murky boundaries with respect to content. Indeed, a growing number of respected environmental leaders and policy analysts now include vehicle emissions as well as emissions from gasoline production and distribution as a “must lower” part of a needed comprehensive national, state and local set of emission reduction initiatives, particularly,if the nation is to meet temperature targets. Further, there is an admission that is becoming almost pervasive: that renewable fuels and renewable fuel powered vehicles, while supported by most of us, are not yet ready for prime time.

While ethanol, methanol and biofuels are not without criticism as fuels, they and other alternative fuels are better than gasoline with respect to emissions. For example, the GREET Model used by the federal government indicates that ethanol (E85) emits 22.4 percent less GHG emissions (grams per mile) when compared to gasoline (E10). The calculation is based on life-cycle data. Other independent studies show similar results, some a higher, others a lower percent in reductions. But the important point is that there is increased awareness that alternative fuels can play a role in the effort to tamp down GHG.

So why, at times, are some environmentalists and advocates of alternative fuels at loggerheads. I suspect that it relates to the difference between perfectibility and perfection. Apart from those in the oil industry who have a profit at stake in oil and welcome their almost-monopoly status concerning retail sales of gasoline, those who fear alternatives fuels point to the fact that they still generate GHG emissions and the assumption, that, if they become competitive, there will be less investment in research and development of renewables. Yes! Alternative fuels are not 100 percent free of emissions. No! Investment in renewables will remain significant, assuming that the American history of innovation and investment in transportation is a precursor of the future.

Putting America on the path to significant emission reduction demands a strong coalition between environmentalists and alternative fuel advocates. Commitments need to be made by public, private and nonprofit sectors to work together to implement a realistic comprehensive fuel policy; one that views alternative fuels as a transitional and replacement fuel for vehicles and that encompasses both alternative fuels and renewables. Two side of the same policy and behavior coin. President Franklin Roosevelt, speaking about the travails of the depression, once said, “All we have to fear is fear itself.” His words fit supporters of both alternative fuels and renewables. Let’s make love, not war!

The U.S. and China on methanol: Two roads converge

/in , /by

Nobel-Prize-winning chemist George Olah recently put methanol front and center again with a powerful Wall Street Journal editorial arguing for the conversion of carbon dioxide emissions from coal plants into methanol for use as a gasoline substitute in our car engines. Co-writing with University of Southern California trustee Chris Cox, Olah noted, “Thanks to recent developments in chemistry, a new way to convert carbon dioxide into methanol — a simple alcohol now used primarily by industry but increasingly attracting attention as transportation fuel — can now make it profitable for America and the world to reduce carbon-dioxide emissions.”

The authors argued that President Obama’s recently announced policy of mandating carbon sequestration for emissions from coal plants wastes a potentially valuable resource. “At laboratories such as the University of Southern California’s Loker Hydrocarbon Research Institute [founded by Olah], researchers have discovered how to produce methanol at significantly lower cost than gasoline directly from carbon dioxide. So instead of capturing and “sequestering” carbon dioxide — the Obama administration’s current plan is to bury it — this environmental pariah can be recycled into fuel for autos, trucks and ships.”

Olah, of course, has been the principal advocates of methanol since his publication of “Beyond Oil and Gas: The Methanol Economy,” in 2006.

To date, he has been recommending our growing natural gas supplies as the principal feedstock for a methanol economy. But the emissions from the nation’s coal plants offer another possibility.

This is particularly important since indications are that the Environmental Protection’s Agency’s assumption that a regulatory initiative will “force” the development of carbon-sequestering technology may be mistaken. A recent report from Australia’s Global CCS Institute said that, despite widespread anticipation that carbon capture will play a leading role in reducing carbon emission, experimental efforts have actually been declining.

The problem is the laborious task of storing endless amounts of carbon dioxide in huge underground repositories plus the potential dangers of accidental releases, which have aroused public opposition. Olah and Cox write, “By placing the burden of expensive new carbon capture and sequestration technology on the U.S. alone, and potentially requiring steep cuts in domestic energy to conform to carbon caps, the proposal could send the U.S. economy into shock without making a significant dent in global emissions… In place of expensive mandates and wasteful subsidies, what is needed are powerful economic incentives. These incentives should operate not just in the U.S., but in other countries as well.”

All this brings into stark relief the diverging paths that China and the United States have taken in trying to find some alcohol-based fuels to substitute in gas tanks. While Olah has been advocating a transformation to a methanol economy in this country, China is actually much further down the road to developing its own methanol economy. There are now more than a million methanol cars on the road in China and estimates show the fuel substitutes for 5-8% of gasoline consumption — about the same proportion that corn ethanol provides in this country.

In this country, the proposal has been that we derive methanol from our now-abundant supplies of natural gas. California had 15,000 methanol cars on the road in 2003 but curtailed its experiment because gas supplies appeared to be too scarce and expensive! Instead, the main emphasis has been on tax incentives and mandates to promote corn ethanol.

China has vast shale gas supplies and could benefit from America’s fracking technology. We could benefit strongly from China’s greater experience in developing methanol cars. The pieces of the puzzle are all there. Perhaps Olah’s proposal may be the catalyst that puts them all together.

Ironically, all this began with a Chinese-American collaboration in 1996. At the time, China had little knowledge or interest in methanol but was persuaded by American scientists to give it a try. Ford provided a methanol engine and China began ramping up its methanol industry and substituting it for gasoline. As a result, China is now the world’s largest producer of methanol, with about one-quarter of the market.

A year ago the Chinese national government was about to mandate a 15% percent methanol standard for gasoline when it ran into opposition from executives in its oil industry. Those leaders have since been deposed, however, and the 15% mandate may go ahead this year. In the meantime, provincial governments  have developed their own standards, with the Shanxi province west of Beijing in the lead.

Ironically, because methanol is only half the price of gasoline, many local gas stations are diluting their gasoline with methanol anyway in order to shave their costs. As a 2011 Energy Policy article by Chi-jen Yang and Robert B. Jackson of Duke University’s Nicholas School of the Environment reported, “Private gasoline stations often blend methanol in gasoline without consumers’ knowledge… In fact, its illegal status makes methanol blending more profitable than it would be with legal standards. Illegally blended methanol content is sold at the same price as gasoline. If legalized, standard methanol gasoline would be required to be properly labeled and sold at a lower price than regular gasoline because of its reduced energy content. Such unannounced blending is now common in China.”

So both countries are feeling their way toward a methanol economy. As Olah points out, the problem in the U.S. is that the various advantages given to ethanol have not been extended to methanol.“One means of addressing this inequity would be for Congress to pass the bipartisan Open Fuel Standard Act of 2013, which would put methanol, natural gas, and biodiesel on the same footing as ethanol (but without subsidies and without telling consumers which one to choose) for use in flex-fuel cars.”

In China, the concern is about coal supplies but this could be alleviated with help from America’s fracking industry or by implementing Olah’s new technology for tapping coal exhausts.

Either way, the pieces are all there. It may be time to start putting them together.
