An engineering "David" has prevailed for the moment over an engineering giant.

Has an engineering "David" really prevailed over the German giant, or is it an outlaw run?

A hydrogen-powered “streamliner” claims to have beaten the BMW H2R to move into the land speed record books. The H2R had posted a 186 mph top speed record during an FIA sanctioned run in Germany, which requires the speed by maintained for one mile, among other technical requirements.

So until the timing is completed, sorted, certified and accepted by sanctioning bodies, such as the FIA, the BMW apparently still holds nine records for hydrogen-fueled cars running with an internal combustion engine. Wanna bet we haven’t heard the last on this from BMW?

The Quantum car, driven by Jesse James, was clocked at 199.712 mph at El Mirage Dry Lake Bed in the Mojave Desert last week. The publicity stunt will be shown on “Jesse James Is a Dead Man” on Sunday, August 9 at 10:00 PM on Spike TV.

The run was supported by 24 Quantum hydrogen injectors that fuelled an 8-cylinder engine, provenance unspecified, which was rated at 704 horsepower. Quantum claims its patented fuel injector has been “designed, tested and validated” specifically for precision fuel metering and durable service with cleaner burning, dry gaseous fuels such as hydrogen and natural gas.

Subscribe to TheDetroitBureau.comQuantum’s gaseous fuel injectors are used in Ford’s hydrogen internal combustion engine vehicles and Toyota Prius and Escape hydrogen hybrid electric vehicles, which have been developed by Quantum. All are technical curiosities right now — albeit of the advanced research sort — rather than serious alternatives to existing technology.

While completely impractical now, there are reasons to keep researching hydrogen fuels.

The Quantum car was fitted with three, carbon-fiber composite, 5,000 psi rated, hydrogen storage cylinders made by Quantum. Among the many, many challenges facing hydrogen as a fuel is where it comes from and how to store it.

Hydrogen as a gas has reasonable energy density by weight, but extremely bad energy density by volume when compared with gasoline. That is why it requires a much larger fuel tank — or tanks — to store it when compared to the gasoline tank in your car. Then you get into age old trade-offs that seriously diminish its practicality as a fuel. A larger tank means a heavier tank to store anywhere the near the energy need for practical driving range, unless you want to run a couple of miles at a time between refueling like a dry-lake racer. Increasing the gas pressure improves the energy density by volume somewhat, but now you are into complex, expensive systems.  

To address this Quantum has developed 3,600 psi natural gas on-board storage cylinders, and 5,000 and 10,000 psi hydrogen storage cylinders, along with the related valves and pressure management systems.

While completely impractical now, there are reasons to keep research into hydrogen fuels ongoing. A fuel cell vehicle — in theory — is radically different approach to transportation than that taken by internal combustion engines. As in battery-electric vehicles, a fuel cell vehicle (FCV) is driven by an electric motor or motors. However, battery vehicles use electricity from an external source, while fuel cell vehicles can create their own electricity. Using pure hydrogen to do this emits no pollutants, while using hydrogen-rich fuels and a  “reformer” to convert them to hydrogen produces some small amount of air pollutants.

As we said, a fuel cell vehicle can be fueled with pure hydrogen gas, which needs to be stored on-board in expensive high-pressure tanks. One potential work around to the problem is to use hydrogen-rich fuels — methanol, natural gas, or even gasoline — but these fuels must first be converted into hydrogen gas by the reformer. It’s like buying your own oil refinery with the car, and about as expensive.
