You may think hydrogen power is some futuristic fantasy, fit only for science-fiction writers. Or, at best, you might consider it a promising technology that won’t be ready for prime time for another 40 to 50 years. If so, think again. In a special edition on “Best Inventions 2006,” Time magazine praises the decision by Shanghai-based Horizon Fuel Cell Technologies “to design and market the H-racer, a 6-inch-long toy car that does what Detroit still can’t. It runs on hydrogen extracted from plain tap water, using the solar-powered hydrogen station.”

Hydrogen vehicles are not mere toys. More than 500 are on the road today. A BMW prototype with a hydrogen internal-combustion engine attained a top speed of 186 miles an hour. Mazda, Ford, Honda and GM are developing a variety of hydrogen-powered engines. Perhaps most exciting, Honda is now powering zero-emission vehicles with hydrogen derived from tap water in small stationary units that drivers can keep in their garages.

We believe the rapid pace of invention, testing and commercialization of fuel-cell technologies is a strong sign that we are entering the early stages of a hydrogen revolution. Instead of waiting half a century as critics suggest, the large-scale production of hydrogen fuel-cell cars could begin very soon. We have come to a crossroads where a single, courageous decision by a few world leaders could launch a new era of progress. That decision is, of course, to shift from our dependence on environmentally damaging fossil fuels to plentiful, renewable and clean-burning hydrogen fuel.

Not everyone sees the bright future of the hydrogen age. Some well-informed energy experts contend hydrogen will be viable only after 20 to 30 years of development. The respected environmental think tank Worldwatch Institute, cautions, “Despite recent public attention about the potential for a hydrogen economy, it could take decades to develop the infrastructure and vehicles required for a hydrogen-powered system.” Joseph Romm, author of The Hype About Hydrogen, states that, “Hydrogen vehicles are unlikely to achieve even a 5 percent market share by 2030.”

These predictions are needlessly pessimistic, based on common misconceptions about the cost, efficiency and technology of hydrogen. If we make hydrogen a national and international priority, as outlined below in a strategy for launching the hydrogen economy, we foresee the first affordable hydrogen fuel-cell cars coming to market starting between 2010 and 2012, and achieving 5 percent of the new car market share by 2020 or sooner.

Let’s examine the critics’ misconceptions about hydrogen.

Myth No. 1: A hydrogen industry needs to be built from scratch The production of hydrogen is already a large, mature industry, and the global hydrogen industry annually produces 50 million metric tons (50 billion kilograms) of hydrogen, worth about $150 billion. To put that into perspective, the current global output of pure hydrogen has the energy equivalence of 1.2 billion barrels of oil, or about a quarter of U.S. petroleum imports. The hydrogen industry is growing at 6 percent a year, thus doubling every 12 years. All this is happening without the incentives that would be provided by a growing fleet of hydrogen fuel-cell vehicles in need of fuel. If the hydrogen industry can expand so quickly “below the radar,” it will have no problem expanding quickly enough to fuel the needs of hydrogen fuel-cell cars in the future.

Myth No. 2: Hydrogen is too dangerous for common use This myth begins with the hydrogen-filled German zeppelin, the Hindenburg, which blew up at Lakehurst, New Jersey, in 1937. Recently that event was revisited in a detailed analysis by National Aeronautics and Space Administration (NASA) scientist Addison Bain. He found that it was not the hydrogen that originally combusted, but the dirigible’s outer coating, a highly flammable material similar to that used in rocket propellants. In reality, the hydrogen industry has had an excellent safety record for decades. In 30 years, liquefied hydrogen shipments have logged 33 billion miles. During all this time, no product losses or fires were reported. Gasoline, our automotive fuel of choice, is 22 times more explosive and has a dismal safety record in comparison.

Hydrogen, while flammable, is generally more easily managed than hydrocarbon fuels. If hydrogen is ignited, it burns with a clear flame and only one-tenth the radiant heat of a hydrocarbon fire. The heat that is produced tends to dissipate much more rapidly than heat from gasoline or oil fires. The bottom line is that hydrogen-safety critics should turn their fire against gasoline, and agitate for the rapid adoption of hydrogen on safety grounds alone! Myth No. 3: Hydrogen can’t be distributed via existing pipelines The transportation of hydrogen, one of the most frequently mentioned concerns of critics, is easily accomplished through pipelines. Creating a new pipeline network to move hydrogen is unnecessary; we can use the one already in existence. Some existing pipelines are already hydrogen-ready. The others can easily be modified with existing technologies by adding polymer-composite liners, similar to the process used to renovate old sewer pipes. Using existing pipelines creates no additional safety concerns. Already, hydrogen-refueling stations are appearing in California, Florida and British Columbia. Other regions are sure to follow.-More>
