A Hydrogen Economy Is a Bad Idea

By David Morris, AlterNet. Posted February 24, 2003.

When George Bush proposed a $1.7 billion program to promote hydrogen-fueled cars in the State of the Union Address, both sides of the aisle applauded. Almost everyone supports a hydrogen economy -- conservatives and liberals, tree huggers and oil drillers. Such unanimity forecloses serious discussion. That's unfortunate. An aggressive pursuit of a hydrogen economy is wrongheaded and shortsighted.

To understand why, we need to start with the basics. Hydrogen is the most abundant element on the planet. But it cannot be harvested directly. It must be extracted from another material. There is an upside to this and a downside. The upside is that a wide variety of materials contain hydrogen, which is one reason it has attracted such widespread support. Everyone has a dog in this fight.

Renewable energy is a very little dog. Environmentalists envision an energy economy where hydrogen comes from water, and the energy used to accomplish this comes from wind. Big dogs like the nuclear industry also foresee a water-based hydrogen economy, but with nuclear as the power source that electrolyzes water. Nucleonics Week boasts that nuclear power "is the only way to produce hydrogen on a large scale without contributing to greenhouse gas emissions."

For the fossil fuel industry, not surprisingly, hydrocarbons will provide most of our future hydrogen. They already have a significant head start. Almost 50 percent of the world's commercial hydrogen now comes from natural gas. Another 20 percent is derived from coal.

The automobile and oil companies are betting that petroleum will be the hydrogen source of the future. It was General Motors, after all, that coined the phrase "the hydrogen economy".

What does all this mean? A hydrogen economy will not be a renewable energy economy. For the next 20-50 years hydrogen will overwhelmingly be derived from fossil fuels or with nuclear energy.

Consider that it has taken more than 30 years for the renewable energy industry to capture 1 percent of the transportation fuel market (ethanol) and 2 percent of the electricity market (wind, solar, biomass). Renewables are poised to rapidly expand their presence. A hydrogen economy would be a potentially debilitating diversion.

As the President's 2004 budget demonstrates, any new money for hydrogen will be taken largely from budgets for energy efficiency and renewable energy. From a federal point of view, then, the more aggressively we pursue hydrogen, the less aggressively we pursue more beneficial technologies.

To be successful, a hydrogen initiative will require the expenditure of hundreds of billions of dollars to build an entirely new energy infrastructure (pipelines, fueling stations, automobile engines). Much of this will come from public money. Little of this expenditure will directly benefit renewables. Indeed, it is likely that renewable energy will have about the same share of the hydrogen market in 2040 as it now has of the transportation and electricity markets.

Far better to spend the billions the President wants to spend on hydrogen to increase renewable energy's share of the energy market from 1-2 percent to 25, 35, or even 50 percent in the same time frame.
