Problems of Hydrogen Distribution

Here is an interesting study of the German auto industry R&D with regard to hydrogen fuel-cell vehicles. The study is called “R&D focus of German Hydrogen Innovation System” and seems to be based on a theory that testing and subsequent implementation can not happen until a suitable “innovation system” comes about. They study the hydrogen research from 1974 to 2000 in Germany because they call it a “frontrunner” in the EU.

Not surprisingly, and as I have suggested before, the risk and uncertainties of a hydrogen infrastructure remain a major obstacle to its use in a distributed network for automobiles:

What is the logical way out of this visible trend in the German R&D sector? As argued earlier, the R&D behaviour of the car manufacturing industry can be explained by the uncertainties they perceive in terms of infrastructure development and these uncertainties are very difficult to manage. A way out therefore, depends strongly on reducing the uncertainties regarding infrastructure. This requires a strong party that acts as a system intermediary. The role of this intermediary is to bring together the parties involved in a future hydrogen economy (like is done in the Californian Fuel Cell Partnership) but is also capable of arranging strong commitments in terms of infrastructure development. Hereby reducing the uncertainty for all actors involved. Since the stakes are so high and the process so capital intensive this is a role that most likely only a strong government can play. This is in line with history that shows that the majority of our current infrastructures (roads, electricity, natural gas) are controlled and coordinated by governments. When the transition to hydrogen is really taken seriously by governments, just funding of R&D is likely not to be sufficient. A strong coordination effort should accompany these financial initiatives

And yet we see some in the US government discussing hydrogen fuel-cell as though the infrastructure will magically appear. Will the oil companies build it? Not likely, unless the government subsidizes them and pays for the risks, which just begs the next question; Will the government build it? Why would they when there are other more stable and certain existing sources of fuel distribution? Well, the motive is not clear (false hope? pride? machiavellianism?) but the consequences are clear:

On July 21, 2005, Governor Arnold Schwarzenegger signed Senate Bill 76 (SB 76) that provided the necessary funding and legislative guidelines to implement recommendations of the CA H2 Net Blueprint Plan. SB 76 is a budget trailer bill that provides $6.5 million in funding for state-sponsored hydrogen demonstration projects until January 1, 2007. The funds may be used for co-funding the establishment of up to three hydrogen fueling station demonstration projects and the State lease and purchase of a variety of hydrogen fueled vehicles.

Close to $7 million dollars to build three stations and buy a few cars. Since funding runs out in 2007, that leaves three years to achieve the Governor’s vision:

To expedite the transition of our transportation system away from petroleum fuels, towards hydrogen fuel and vehicles, experts point to the crucial need for a hydrogen fueling infrastructure and the necessary leadership to make it a reality. An early network of only 150 to 200 hydrogen fueling stations throughout the State (approximately one station every 20 miles on the State’s major highways) would make hydrogen fuel available to the vast majority of Californians. This early vision for California’s Hydrogen Highway Network is achievable by 2010 and will help demonstrate the economic and technical viability of hydrogen technologies. Studies by the California Fuel Cell Partnership and others estimate that this initial low-volume fueling network will cost $75 – $200 million, the majority of this investment coming from private investment by energy companies, automakers, high-tech firms, and other companies.

One station every twenty miles? How does that compare to the number of existing gas and diesel stations? $75 – $200 million is a big spread. The numbers factor out to $375K to $1.3 million per station. The cost of blending biofuels into existing gas and diesel stations would be a tiny fraction of those numbers. Speaking of numbers:

200 stations x every 20 miles = 4000 miles

That is double the number of “Interstate” miles in California, according to the California Highways site:

The Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 brought the total authorized milage to 43,000. Of these miles, California has been allocated 2,311 miles.

That sounds great, until you take into account that Interstate miles are a tiny fraction of commonly traveled roads:

The Interstate system (formally “The Dwight D. Eisenhower System of Interstate and Defense Highways”) serves the 48 contiguous states, Alaska, Hawaii, Puerto Rico, and the District of Columbia. It carries more than 21 percent of the nation’s traffic on only 1% of the nation’s total road and street mileage.

The other 80 percent of people on 99% of the roads will have no hydrogen until someone, something, somehow figures out a sustainable distribution system. The CA governor clearly thinks it will be private industry subsidized by taxpayers. The report above thinks it will be the government. Neither has demonstrated a suitable “innovation system” that can bring a solution by 2010.

When you look at a cost/benefit analysis of energy distribution, hydrogen has serious problems of security (e.g. gas/liquid pressure and loss), while biofuels and hybrids are standing by as proven safe and reliable. Could the same level of investment in biofuels result in same or greater emissions changes by 2010 than combined hydrogen use for the five years afterwards?

Don’t get me wrong, research on hydrogen is great but I wish elected officials could be realistic about the need for a secure (e.g. sustainable) and clean source of energy that people can use on the road today. Progress today does not mean stump speeches about the great big hydrogen companies that will run our energy system ten years from ten years from now.

Go ahead, send Arnold a note and ask him how he gets around in his hydrogen Hummer.

The H2H puts lipstick on the pig by turning a vehicle whose urban fuel economy is about 10 miles per gallon (filling the tank routinely costs over $50) into a futuristic, alternatively-fueled car whose main tailpipe emission is water vapor.

So there you have the typical marketing pitch. Did you know that with hydrogen you can turn water into wine, rocks to pearls…tomorrow? The story concludes:

GM does not allow Schwarzenegger to use the “Self-Serve” lane at the hydrogen station. The company fills the tank itself, keeps the vehicle in Lake Forest, Calif. (near its engineering facilities and Quantum’s offices) and requires that a GM engineer ride in the car at all times. Is Hummer’s tentative embrace of green technology sparked by conscience or sales? Noting that Hummer’s North American sales in the first 11 months of 2004 declined 19% compared to the same period in 2003, the refashioning of Hummer starts to make sense–even if selling Hummers on their fuel economy still sounds like a desperate move.

Desperate and, quite frankly, not innovative enough.

Toyota rides sustainability wave

Sales are booming for the hybrid maker Toyota. They say sales are up for all their vehicles, including SUVs, but I find it particularly interesting that they are now talking about making over 300,000 hybrids a year. Just a couple years ago they were tepid about making less than 50,000 a year, concerned that the market would be small or fail to evolve. Now the news is that the company is firing on all eight batteries:

Japanese car firm Toyota has seen its vehicle sales soar in September, compared to a year earlier, in sharp contrast to those of its US rivals. The car firm saw year-on-year sales rise 20%, helped by sales of passenger cars…

[…]

Sports Utility Vehicles (SUV) and trucks – traditionally major businesses for US car firms – have lost their appeal in recent months with rising oil prices.

This trend was confirmed by Ford’s results, which saw car sales rise by 26.2% for the period – while sales of its trucks declined by 5.5%.

Also interesting is that the US companies are now even talking about taking bonuses back from executives:

After a board meeting on Tuesday, GM said it would change its bylaws to require that executives return bonuses or incentive compensation, should the firm restate its financial results.

On what strange computer did they figure bonuses when their company was headed for major headaches? Is this like the captain of the Titanic pushing for more speed as he boasted of the ships resiliance to disaster? Were the numbers simply wrong, or was GM and Ford management unable to understand the warning signs?

GM Diesel Hybrid: Opel Astra

Boy, I really missed this announcement. Then again, I’m not sure anyone else saw it either. Back in January 2005, GM said it was working on an exciting new hybrid-diesel platform:

With fuel consumption below 4-liters/100km (MVEG mix), the Astra Diesel Hybrid is projected to be 25 percent more fuel-efficient than comparable diesel models.

[…]

The two-mode full hybrid technology can provide a significant reduction in fuel consumption helping to meet ever-stringent carbon-dioxide emission targets. Its scalability enables the technology to be applied to markets around the world.

[…]

1.7L CDTI with 92-kw/125-hp and 280-Nm/206 lb-ft of torque; with maintenance-free particulate filter

And since then, nada. No news on this concept car. Instead, in January 2006, GM announced a new fashion concept: the hybrid Tahoe. It is like ordering a low-fat BigMac.

The front of the Chevrolet Tahoe Two-mode Hybrid has been lowered 10 mm compared to the conventional Tahoe, which provides additional aerodynamic benefits as well as a smoother and sleeker appearance.

Lowriders are really just guys trying to get a few extra mpg out of their classic Cadillacs and Buicks, right? Reminds me of the Range Rover’s variable height said to increase mpg from 8 to 10 when used to lower the flat-boxy SUV at highway speeds. Hey, every little bit counts, even though they marketed it as a comfort, safety and off-roading stability feature (would you buy a Range Rover for any other reason?). Sorry, I digress:

“This truly looks like a special vehicle,� said [Design Manager David] Smith. “It is packed with details, and every one of them serves a function.�

Looking good is a function, right? Especially to the Design Manager. The function of all that chrome is…

There’s no mistaking this truck for anything other than a hybrid: Badging appears on the C-pillar, on the rear liftgate and on the hitch cover.

Of course. A giant SUV is so clearly a hybrid vehicle that GM decided they would paste big colorful badges all over it saying “Don’t hate us for our high-margin SUV, it’s a hybrid”.

Other aerodynamic refinements include sharpening of the D-pillar rearward, including the taillamps, a CHMSL appliqué detail spoiler over the rear hatch and a closeout panel under the back of the vehicle to facilitate airflow.

Lightweight, aero-efficient wheels with the lowest rolling-resistance tires available for full-size trucks further trim fuel use, and are complemented with a tuned ride to provide the ride and handling performance and attention to detail that customers expect from a totally integrated vehicle.

Ah, now I get it. They’re trying to make it *cool* and *hip* to be hybrid. Cool and hip means driving a Tahoe, thus they were pushed into this decision by the consumers. Maybe they will find some well-dressed androgenous actors to drive the new Tahoe in advertisements. Ok, bad joke. But the fact that SUVs are high-margin does not excuse the fact that the smaller cars are really more efficient right now, especially the smaller hybrid-diesel.

Perhaps instead of this exercise in finding new shades of lipstick for a pig, some GM marketing muscle could be put into technology developments that could put GM back on the map.

I mean, just for perspective, compare the above “wowy, zowy” super cool Tahoe press release language with the ultra-nerd tone for the Astra:

From the outside, the Astra Diesel Hybrid, with its unique panoramic glass roof, doesn’t look much different from a production-version Astra GTC.

Hmmmm. No badges? How uncool. And why isn’t it lowered with chrome wheels? Oh, wait, this is for the european market.

Inside, however, the tachometer in the gauge cluster has been replaced by instruments that provide feedback on the operation of the hybrid propulsion system, such as traction provided by the electric motors, traction from the diesel engine, or both. Another gauge displays the battery’s charge level. Also, a video animation in the graphic information display located in the center console depicts the current propulsion state of the vehicle when it’s driving.

Ah, yes, instruments showing the “current propulsion state”; what every car buyer wants to know when they look for a car.

I have to admit I’m happy that GM is headed towards hybrids, but if only they could try a little harder to get real things really rolling. After all, McDonald’s serves salads now and I hear they are not only tasty but bringing home the bacon:

The world’s largest fast-food chain also Tuesday announced the sale of its new Asian Premium salad, expected to be the company’s largest seller, according to industry experts.

Judge rules for caution on environment

The story is really about preserving endangered US mountain carribou from weekend-warrior snowmobile enthusiasts, but I thought this quote was worth pointing out:

Citing aerial photographs that show snowmobile tracks crisscrossing caribou routes to vital feeding areas, the judge added, “The court chooses to be overprotective rather than under-protective.”

And why not? If you move the snowmobiles to another location, or require them to reduce their pollution (noise and emissions), is there any real difference? Whereas if you do not, the carribou may be gone forever. Seems like the judge made a wise call, in terms of risk. The article goes on to show a little irony:

Snowmobile interests have countered that the herd has shrunk over the decades mostly because of past logging, backcountry skiing and global warming

Global warming, likely to be caused by exhaust. And snowmobiles are one of the worst polluters, each engine putting out the equivalent exhaust of 1,000 cars as I’ve mentioned before. Think about that for a second. Just one hundred snowmobiles would put out 100,000 cars worth of exhaust.

The risk actually identified by the animal experts was that the heavy snowmobiles pack down so much snow that it prevents the caribou from escaping their enemies in deep powder. They also argued that the noise of the unregulated engines disturbs the caribou enough to hurt their feeding and calving. These claims make sense, and were apparently well documented, especially when compared to the “it’s because of global warming, not because of the engines that might be a major contributor to global warming”. Interesting that the snowmobile interests wanted to argue about disturbances caused by backcountry skiing. With logic like that, it is no wonder the judge decided to send the snowmobiles packing. Did the defense present photos of angry-looking ski couples making nasty faces at the caribou? Perhaps they had evidence of the latest ski fashion colors causing a loss of caribou appetite?
