The Myth of the Hydrogen Economy

Robert Zubrin, from The New Atlantis, does an excellent job of debunking the theory that hydrogen will replace gasoline in the economy of the future:

If we are to achieve any progress on this most critical issue, the myth of the hydrogen economy needs to be debunked. It is bad science, bad economics, and bad public policy.

And even if you are among those willing to sacrifice freedom and economic rationality for the sake of the environment, and therefore prefer hydrogen for its advertised benefit of reduced carbon dioxide emissions, think again. Because hydrogen is actually made by reforming hydrocarbons, its use as fuel would not reduce greenhouse gas emissions at all. In fact, it would greatly increase them.

Zubrin also discusses another possible alternative, methanol, in his review of the book Beyond Oil and Gas: The Methanol Economy. According to the review, the future looks considerably better for methanol,

The authors dub their proposal the “methanol economy.” Methanol is commonly known as “wood alcohol” because it can be produced from wood; it can also be made from coal, natural gas, methane hydrates, any type of biomass, or urban waste. It can be used as fuel for internal-combustion engines, and eventually in fuel-cell vehicles. It can also be used as feedstock for producing dimethyl ether, an excellent fuel for non-polluting diesel engines. In short, it is a convenient medium for storing energy and is easily transported and dispensed as a fuel.

Integrating methanol into our energy system would have numerous benefits in the not-so-distant future. As the authors point out, it would make the transportation of liquid natural gas much safer by converting it to less-hazardous liquid methanol before shipping it. Methanol could also be used to produce plastics, synthetic fabrics, and many other non-fuel products currently made from petroleum.

Importantly, methanol can also be produced (in conjunction with an auxiliary electricity source, like nuclear power) by chemically recycling carbon dioxide, which can be found naturally in the air or readily captured from atmosphere-polluting industrial emissions. The methanol produced can, in turn, be used to produce synthetic hydrocarbons and other products now obtained from fossil fuels. If successfully tapped, methanol “has the ability to liberate mankind from its dependence on fossil fuels for transportation and hydrocarbon products,” while reducing the amount of carbon dioxide pumped into the atmosphere.

And finally, Stephanie Cohen walks us through the unique energy visions pronounced by both Republicans and Democrats and tracks the development of US energy policy through the past few centuries.
