Reuse-recycle programs are now becoming a huge part of both shale and Combined Cycle Gas Turbine (CCGT) operations, saving water and reducing other impacts.

During the past 30+ years, USA energy fuel usage has changed from predominance of coal and foreign oil to shale natural gas and oil. In addition, both the technology and role of wastewater treatment firms have evolved from specialized product line to comprehensive menu of unit operations – capable of reducing effluents to approximately drinking water quality.

Background

Shale gas, derived from hydraulic fracturing and horizontal drilling, has yielded a market price of under $3/MMBTU for the past few years – from $12/MMBTU in 2008 – a 75% reduction resulting in a 40% cut of Combined Cycle Gas Turbine (CCGT) operating costs. Low cost natural gas generated from hydraulic fracturing and horizontal drilling supports converting older coal-fired power plants into natural gas fired units. 

This trend of continued reliance on shale gas for base-loaded power plants will continue. The siting of new drilling facilities and power plants offer an opportunity to comply with wastewater discharge regulations and water scarcity by adopting reuse recycle management. This discussion examines the potential for reuse-recycle programs in addressing shale gas production and gas-fired power plant wastewater issues.
