Back around 2001, I was working at DuPont's Sabine River Works in Orange, Tx. Conoco was building two huge CoGen Turbine Electric Generators on DuPont's property, with DuPont providing all the offsite utilities for the facility.
These were General Electric design turbines. The idea was Natural Gas fueled feed stock, with the added benefit of a way to burn off nasty Volatile Organic Compound (VOC) byproducts, from the six or seven other chemical plants along there. I think cheap electricity for them all as well.
These were like big jet engines, six stories tall, and tall exhaust stacks. Supposedly they were going to build twenty of these units around New York City. I don't if that ever happened, but years later, I worked with a guy who did one on a barge in Venezuela, that could be moved to different locations along the coast.
Natural gas should be a viable, cheap fuel in some locations, for many years to come.
