Natural gas prime movers: A prime income opportunity?
Although almost every factory, for example, uses compressed air to operate and control equipment--from power tools to packaging machinery--most air compressors are driven by electric motors. Similarly, although industry uses refrigeration for everything from freezing food to chilling warehouses to making chemicals and ice to operating skating rinks, natural gas powers only about 100 industrial refrigeration units in North America. But several factors are beginning to make natural gas more attractive as a prime mover. For one thing, the rising cost of electricity, with its demand or time-of-day and summer on-peak charges, has everyone looking for ways to cut their electric bills. At the same time, in the wake of deregulation of the nation`s electric industry, customers can build on-site power plants that use natural gas to generate their own electricity, or have outside power suppliers or energy service companies (ESCOs) do it for them. Waste and exhaust heat, which can represent up to 60% of the total energy supplied from both engines and turbines, can be captured and used. Finally, growing concern over electric power outages has made natural gas more attractive for mission-critical operations, while new financing options let people buy and install natural gas prime movers more easily.
