Natural Gas

The Natural Gas parameter screen is shown for both PC and NGCC plants. The following parameters are shown:

•Fuel Extraction Method: Natural gas can be extracted by conventional drilling or hydraulic fracturing. Conventional drilling is the default.

•Fuel Transport Method: Natural gas can be transported by pipeline or as Liquefied natural gas (LNG). Pipeline is the default.

•Fuel Extraction: The following parameters specify the water needed for natural gas extraction:

•Water Withdrawal Factor: This parameter measures the water withdrawal intensity in gallons of water per volume (MMscf) of natural gas extracted.

•Water Consumption Factor: This parameter measures the water consumption intensity in gallons of water per volume (MMscf) of natural gas extracted.

•Fuel Processing: The following parameters specify the water needed for natural gas processing:

•Water Withdrawal Factor: This parameter measures the water withdrawal intensity in gallons of water per volume (MMscf) of natural gas processed.

•Water Consumption Factor: This parameter measures the water consumption intensity in gallons of water per volume (MMscf) of natural gas processed.

•Fuel Transport: The following parameters specify the water needed for natural gas transport:

•Water Withdrawal Factor: This parameter measures the water withdrawal intensity in gallons of water per volume (MMscf) of natural gas transported.

•Water Consumption Factor: This parameter measures the water consumption intensity in gallons of water per volume (MMscf) of natural gas transported.
