The danger of a fuel cell infrastructure

A cursory review of the “Comparison of hydrogen, methanol and gasoline fuels…” in the Journal of Power Sources 79 (1999) 143-168, brought up a curious argument. Joan Ogden, Margaret Steinbugler and Thomas Kreutz suggest the following, on page 166:

Defining ‘infrastructure’ to mean all the equipment (both on and off the vehicle) required to bring hydrogen to the fuel cell, we find that the cost is comparble for hydrogen, methanol and gasoline POX fuel cell vehicles. Hydrogen appears to entail the lowest capital costs.

By how much? And what does that cost look like relative to other more stable and safe sources of fuel that also do not require long-haul centralized distribution? They do not say. Instead, they back away from their own conclusions by offering optimism about hydrogen.

The cost and efficiency estimated for various types of fuel cell vehicles depend on our assumptions, which may change as technology progresses. For example, future improvements in onboard fuel processor technology or development of fuel cells with higher performance on reformates could increase the vehicle efficiency for methonal or gasoline vehicles; better methods of hydrogen storage might lead to lower cost for hydrogen vehicles.

The last sentence is especially important. The amount of security required to properly distribute and store hydrogen fuel is not actually difficult as much as it is incredibly expensive. And the expense is not because of the materials involved, but rather due to the need to retrofit or build out a new system with a constant state of surveillance to avoid loss or damage of this form of energy. Compared to energy sources like biodiesel, which are actually used to clean up petroleum spills and distributed as one of the most environmentally stable forms of fuel, a highly expensive and centralized system of hydrogen seems like exactly the wrong thing to build in a climate of fear from terrorist attack or sabotage.

Since the article is focused on which fuel cell technology is best, it lacks important perspective on whether a fuel cell is really the right choice among all alternative sources. While the US military is running all their engines now on diesel, and spending billions on improvements to supply-chain logistics, this article gives a prediction about fuel cells that is hardly based on real-world experience and thus rather uninspiring:

The capital cost of developing hydrogen refueling infrastructure is comperable to or less than the total cost (on and off the vehicle) for methanol or gasoline fuel cell vehicles. The lifecycle cost of transportation is slightly less for hydrogen than for gasoline or methanol fuel cell vehicles. Like compressed natural gas or methanol, hydrogen faces the issue of reaching beyond centrally refueled fleet markets.

Fuel cell vehicles, even hydrogen, will have to be more realistic before their claims can be validated. For example, today’s gasoline engines could be more efficient, but the car manufacturers and the petroleum companies do not seem inclined to make it happen. They blame the consumer, but no matter who is at fault the fact remains that there has been little/no progress made for over a decade even though the capability exists. And I think we all know that most Americans, especially those driving on the open road at high speed, prefer large, heavy and “safe” feeling vehicles. So economic and cultural factors are important. On the other hand, electric vehicles have long been known to be capable of long distance travel at high-speeds in spite of the efforts by the car manufacturers and petroleum companies to undermine their development. So, with this in mind I have to ask why this report did not point out the more obvious conclusion that hydrogen power-plants fueling electric vehicles would solve the problems of hydrogen distribution as well as power-plant and vehicle emissions. The hydrogen fuel dream could thus be realized, but only as a competitor to other plants but not on an individualized level. Then, after the means of securing the energy had been developed and tested extensively, it would be more reasonable to propose extending it to consumer fueling-stations. Although in the meantime, people might also realize that a diesel-hybrid is far more practical, inexpensive and safe.

Pot. Kettle. Black.

I was reading a critique of literature this morning and noticed that the author was being rather negative and critical of others for being too negative and critical. S/he seemed oblivious to the contradiction, as their writing bemoaned the lack of more positive writing.

A stark problem with the success of the 419 fraud schemes is that the perpetrators often say they do nothing more than let people give them money. The victims fall into a trap of optimism, believing that they have actually found something for nothing. Alas, a little more critical thinking might be just what the doctor ordered for the new and less familiar risks people face online or to deal with a world where common hallmarks of universal rights are being seriously challenged (i.e. the Geneva convention):

Torture may be worse now in Iraq than under former leader Saddam Hussein, the UN’s chief anti-torture expert says.

[…]

Victims come from prisons run by US-led multinational forces as well as by the ministries of interior and defence and private militias, the report said.

Writing will be positive when people feel safe and prosperous (again). On what basis would a person manufacture a positive outlook in the face of great moral, financial or even physical danger? Conversely, prosperity and positivity also brings heightened risk in the forms of threats and vulnerabilities, painfully illustrated by the tragedy of the Cathars. Should proper caution and controls lead to a more universally safe and stable foundation, positive writing may again someday flourish. Until then, attacking people for being too negative is little more than the pot calling the kettle black.

Company Reps Arrested for Ivory Coast Toxic Waste

This is an interesting development in the story about the Ivory Coast toxic waste disaster. The BBC reports:

Two senior French officials of the company whose toxic waste has been dumped in Ivory Coast have been charged with poisoning, an official says.

Dutch-based company Trafigura Beheer BV says it is “shocked” and says the two had gone to help those affected by the waste, which has left seven dead.

Trafigura has always maintained it paid Ivorian firms and officials to dispose of the waste safely.

The timing of their arrest seems to have been a result of them trying to leave the country as much as actual culpability in the disaster. This echoes the already difficult position the French have been playing in the Ivory Coast as peacekeepers, as explained here by the BBC:

In recent years a quiet, relatively prosperous French client state has descended into chaos, and Paris has found it impossible to impose its authority.

Ethanol versus food

Here is another misleading report, this time from Fortune:

We are facing an epic competition between the 800 million motorists who want to protect their mobility and the two billion poorest people in the world who simply want to survive. In effect, supermarkets and service stations are now competing for the same resources.

Sensationalist point, really, since it completely overlooks the simple fact that biofuel production can come from recycling waste instead or or in addition to grain stocks. Even more relevant to the bold claims by Fortune is that production has and can still significantly outpace consumption needs. The problem is not quantity of grain stocks as much as economic and policy decisions that have resulted in waste and graft rather than generosity. I have studied the impact of trade on international stability and security for many years and will never forget the US position twenty years ago. Here is some analysis from 1985 that perfectly describes the unusual economics and politics of US agriculture and foreign aid:

This is a strange and painful year to talk about grain. Our televisions bring us pictures of starving African children, but world grain stocks exceed 190 million tons; a record surplus.

[…]

Worldwide production of wheat and feed grains has grown 20 percent since 1974, 100 percent since 1964. Between 1960 and 1980, food production grew slightly faster than population, yielding a net increase in food supplies per person …

Although this production boom slowed down significantly after 2000, and by 2002 people were warning that climate change (i.e. global warming) could spoil the parade, it is not hard to find agriculture references that still show surplus that could be made into fuel in addition to food:

Compared to the wheat and corn markets, the soybean market has been relatively tame for the last several months. Record large world stocks, increased soybean acreage in the U.S., and prospects for at least a trend yield in the U.S. suggest that surpluses will continue for another year. Soybean oil prices have been supported by speculative demand in light of prospects for increased bio-fuel demand, even though domestic soybean oil stocks have grown to the highest level in four years. Soybean meal prices remain at a low level, reflecting the large supply situation.

Stocks of U.S. soybeans on June 1, 2006 were estimated at 990.1 million bushels, 290.8 million more than on the same date last year and the largest ever June 1 inventory.
