A major roadblock to transitioning to alternate fuels is the infrastructure that will supply them — namely, the extensive pipelines and network of refueling stations to dispense them. Typically referred to as the “chicken and egg” problem, conventional wisdom is that we won’t see widepread adoption of alternate fuels and new vehicles until the infrastructure exists to support them. This article in Car and Driver summarizes the dilemma.
But it’s definitely possible that the existing gas station infrastructure could evolve into the refueling infrastructure of the future. Already there has been considerable work in how to convert gas stations to hydrogen refueling stations, for example. The oil and gas industry is making significant investments in the technologies to make this transition possible, and a number of hydrogen stations have been constructed. (To learn more about where the industry is investing for our energy future, read America’s Oil and Natural Gas Industry -Putting Earnings into Perspective, 2009.) As the major energy companies own only about 10 percent of the gas stations in the U.S., there will be many small businesses that will be involved in this transition.
Initially, the demand for hydrogen fuel can probably be addressed by a few hydrogen producers that transport fuel by truck to a small network of refueling stations. In fact, there are several suppliers delivering now to a reasonably broad geographic coverage. The National Renewable Energy Laboratory (NREL) has an excellent interactive map of the U.S. showing hydrogen and alternative fuel locations in the U.S. Unfortunately, the current cost of delivering hydrogen fuel ranges from 5 to 10 times that of gasoline, and quantities are limited.
So the challenge going forward will be to expand production and distribution, while reducing cost. The “desired state” would be for small networks of refueling stations to be supplied by pipeline. Eventually larger production facilities would be built to service urban areas. This transition may occur over 25 years, says industry expert Carl Nemanich, in The Transition to Hydrogen as a Fuel, from the proceedings of a workshop sponsored by The Pew Center on Global Climate Change and the National Commission on Energy Policy.
Hydrogen is just one of a number of alternative fuels that may become commercially viable and available at a refueling station; we’re now well familiar with E85, but others include biodiesel, compressed natural gas, electricity and propane. Adding any of these alternative fuels to the mix will represent a significant capital investment. In anticipation, gas station owners and suppliers are learning about technical and financial requirements at association meetings and conferences so that they’ll be prepared to implement the most promising fuels as the market develops.
While the media serves up amazing news of alternative energy developments — such as today’s story on a new hydrogen storage method that uses carbonized chicken feather fibers — we still are a long way from seeing alternative fuels replace fossil fuels. (Read this report by American Petroleum Institute about U.S. energy demand growth and fossil fuels through 2030.)
In the interim, our current gas station infrastructure will continue to supply us, while gas station owners and suppliers concentrate on strengthening their businesses, given the tough economic environment.
