They do not demand a new infrastructure. But hydrogen fuel cell cars do. It isn't there yet. It might be there someday. But it might not matter. We have to explore hydrogen like we have explored electric vehicles, although, ultimately, the EVs [electronic vehicles] did not catch on the way some people thought they might. We found people did not like the inconvenience of finding special limited sites for charging them; again, no infrastructure existed." So was I driving the car of the future?

Not to be left out, Daimler-Chrysler's retired board member Jiirgen Hubbert put the total percentage of hydrogen fuel cell cars at about 1 percent by 2012—and he said Daimler aimed to be building most of them.20) Hydrogen derived from natural gas would be profitable to Big Oil and was going to be part of the energy future. But hybrids were now, and the mistake that GM had made was to ignore the consumer market for hybrids.

At Chevron headquarters in San Ramon, California, a hydrogen fuel cell unit is the primary power source for the data center. Chevron has made a commitment to be more energy efficient in their own everyday operations, and new targets are set each year. Since 1992 Chevron's energy efficiency ahs increased by 24 percent. And of course, Chevron is dedicated to helping other companies conserve as well.44 Chevron Energy Solutions (CES), a subsidiary of Chevron, develops energy-efficient facility improvements for public institutions and businesses.

The long-term solution is likely electric, whether the electricity is provided by a super-efficient battery or by a hydrogen fuel cell. Researchers and automakers are looking to electrify the drivetrain, powering vehicles only with electricity and motors, rather than with petroleum fuel and combustion engines. Several years ago, most people would have said that hydrogen-powered cars were the only solution—and exciting new developments from manufacturers like Honda have restored faith not only in hydrogen cars but also in a future hydrogen economy.

To make a hydrogen fuel cell car with the same range as today's gasoline-powered car, with comparable passenger room, would require storing the hydrogen at 10,000 pounds per square inch (psi), which is ultrahigh pressure. This can be done, using ultrastrong carbon fibers to reinforce the tanks. Such a tank might even survive a high-speed crash. The question is whether the more delicate plumbing connections from the tank would survive. If not, hydrogen under extremely high pressure would escape rapidly. Hydrogen is extremely flammable.

Grove built the first hydrogen fuel cell in 1839. As in the case of internal combustion, fuel cells have been continually perfected to the point where they can produce electricity with about 90 per cent efficiency. The cost of fuel cells keeps decreasing as they become ever more common in the marketplace. As promising as these traditional hydrogen energy technologies may be, we come up against fundamental constraints which chemistry places on how much energy we can get out of the hydrogen atom.
