    Care to Write a Testimonial?

    Testimonials From the EV World Update Edition 4.16 - [19731]: Bill Moore (EV World -Chief Editor) concluded his interesting "My Perspective" editorial (reproduced below) with the following plea to those who know his work: "...Finally, I'd like to ask your help, if you're interested...if you feel comfortable with writing a testimonial on my behalf, describing your credentials and your view of my journalistic efforts and writing skills -- and hopefully, not the lack thereof -- I would very much appreciate it. And if you have any recommendations for a budding author, please feel free to share them. Send your email responses to editor@evworld.com, and thank you in advance."

    MY PERSPECTIVE

    Setting the Record Straight
    This week I had the opportunity to talk with Dennis Campbell, the president of Ballard Power Systems, the world leader in PEM fuel cell technology. That 40-minute dialog, the first twenty-one minutes of which is now available on EV World for Premium subscribers, focuses on the question of fuel cell stack durability. My first report from the SAE workshop in Sacramento, entitled "200 Hundred Hours," precipitated the interview. Neither Ballard, nor DaimlerChrysler wished to leave the impression in EV World readers’ minds that 200 hours was the maximum operational life of a PEM fuel cell stack.

    What I learned from our discussion reconfirmed my conviction that fuel cells are a very long-range technological fix to problems that really need immediate attention and solutions today. You have but to read both Peter Eisenberger's and Dr. Joseph Romm's testimony this week before the full House Science Committee to appreciate this. (See my comments on below).

    Certainly, I will be the first person to acknowledge that fuel cells offer an elegantly simple sounding solution for replacing the internal combustion engine. There are no moving parts, the “fuel” is the most abundant in the universe and the only emission is warm water vapor. How much simpler can you make it?

    However, that apparent simplicity conceals a labyrinth of technological, economic and political twists and turns that boggle the mind starting with the complex materials science that goes into the making of a PEM fuel cell. Here's one of the surprises to come out of my interview with Mr. Campbell. Did you know that a PEM fuel cell membrane looks identical of common Saran wrap, the stuff you wrap left-overs in? Of course, it's hugely more expensive, but its also as fragile. Membranes can be made for longevity, transient response, cold-weather start-up, energy density, fuel efficiency, but not all at the same time. Ballard and other fuel cell developers can engineer various iterations of their cells to meet two or three of these criteria, but the technology simply doesn't exist at this point to meet them all. In Campbell's words, it's inch-by inch progress with no dramatic breakthroughs on the foreseeable horizon.

    House Science Committee Testimony
    But dramatic breakthroughs -- in cost-reduction, performance, durability and storage -- are precisely what the hydrogen economy needs, according to testimony this past week in Washington, D.C.

    Appearing before the U.S. House of Representative's Science Committee were four witnesses who offered their views on the nation's commitment to a hydrogen future. Two of the witnesses, Peter Eisenberg from Columbia University and Dr. Joseph Romm, a former-Acting Assistant Secretary of Energy offered what can only be characterized as a "sobering assessment" of the hurdles ahead.

    Here's what Eisenberg said, "...our committee concluded that incremental improvements to existing technology are not sufficient to close all the gaps (in hydrogen technology development). In particular, hydrogen storage is the potential show-stopper.

    "Simply put, for the Hydrogen Initiative to succeed, major scientific breakthroughs are needed. This will not be easy. We cannot simply engineer our way to a hydrogen economy."

    In his 10-page testimony, available at House Committee on Science web site, Romm's assessment was even more critical and alarming. In his remarks, he not only talks about the usual fuel cell obstacles, he also addresses the energy side of the problem. Perhaps most disconcerting of all, he projects that fully two thirds of the world's coal-powered energy capacity in 2030 hasn't even been built yet!

    He stated in his testimony, "Between 2000 and 2030, the International Energy Agency (IEA) projects that coal generation will double. The projected new plants would commit the planet to total carbon dioxide emissions of some 500 billion metric tons over their lifetime, which is roughly half the total emissions from all fossil fuel consumed worldwide during the past 250 years."

    The consequences of such a pathway is likely to result, he warns, in a one degree F temperature rise in the USA every decade. That is more than the entire previous century.

    "Two points are clear," he continues. "First, we cannot wait for hydrogen cars to address global warming. Second, we should not pursue a strategy to reduce greenhouse gas emissions in the transportation sector that would undermine efforts to reduce greenhouse gas emissions in the electric generation sector. Yet, that is precisely what a hydrogen-car strategy would do for the next few decades."

    Sudden Climate Change
    We may not have a few decades to get serious about climate change, as a fascinating article in Physics Today reveals.

    Tracing the history of the evolution of our understanding of how long it takes for climate change to occur, Spencer Weart writes that in the last fifty years or so we've gone from believing climate change was slow and gradual, taking thousands of years, to the chilling realization that dramatic climate change can take less than a decade!

    Weart, who directs the Center for History of Physics at the American Institute of Physics, writes, "Now that the ice had been broken, so to speak, most experts were prepared to consider that rapid climate change -- huge and global change -- could come at any time. 'The abrupt changes of the past are not fully explained yet,' wrote the NAS committee in its 2002 report, 'and climate models typically underestimate the size, speed, and extent of those changes'

    "Although people did not deny the facts head-on," he states, "many denied them more subtly by failing to revise their accustomed ways of thinking. 'Geoscientists are just beginning to accept and adapt to the new paradigm of highly variable climate systems,' wrote the NAS committee. And beyond geoscientists, 'this new paradigm has not yet penetrated the impacts community" -- the economists and other specialists who try to calculate the consequences of climate change. Policymakers and the public lagged even farther behind in grasping what the new scientific view could mean."

    Weart concludes, “In an area as difficult as climate science, in which all is complex and befogged, it takes a while to see what one is not prepared to look for.”

    Care to Write a Testimonial?
    Finally, I'd like to ask your help, if you're interested. I am proposing to write a non-fiction book and I have a potential publisher interested in the subject, which for the moment I'd prefer to keep confidential. I can tell you it isn't about electric cars, though there is a tangible link to important aspects of the hydrogen economy, renewable energy and the environmental community.

    That being said, the editor with whom I am dealing informs me that her editorial review board isn't particularly impressed with the fact that I've published EV World now for more than six years. Apparently, conducting hundreds of interviews and writing as many articles every week for six solid years isn't sufficient. She informs me that I can improve my chances of having my proposal accepted if I can provide some testimonials from respected industry leaders and academicians who are familiar with me.

    Therefore, I would like to ask that if you feel comfortable with writing a testimonial on my behalf, describing your credentials and your view of my journalistic efforts and writing skills -- and hopefully, not the lack thereof -- I would very much appreciate it. And if you have any recommendations for a budding author, please feel free to share them. Send your email responses to editor@evworld.com, and thank you in advance.

    Until next time, stay plugged into EVWorld...
