Three Robert Morris University professors are using a mathematical model to figure out the best places to build natural gas filling stations — and the answer is more complicated than the rationale for building conventional petroleum gasoline stations, reports Paul J. Gough of the Pittsburgh Business Times.
Conventional gas stations have decades of history and the market behind them, Gough notes. Most everyone has a car run by gas; it’s rare to have a private vehicle that runs on natural gas, and there are only a handful of natural gas fueling stations in the Pittsburgh region.
