Duke Energy and its subsidiaries support new Water Research Center
CHARLOTTE, N.C., Oct. 4, 2012
CHARLOTTE, N.C., Oct. 4, 2012 /PRNewswire/ --Duke Energy and its
subsidiaries, including Progress Energy Carolinas and Progress Energy Florida,
have joined with a dozen other companies and the Electric Power Research
Institute (EPRI) in supporting the new Water Research Center (WRC) at Georgia
Power's Plant Bowen in Cartersville, Ga.
A new technology being tested at the research and development center could
significantly reduce the water needed for power plant cooling towers.
The WRC is the first U.S. research facility of its kind, providing a venue for
developing and testing technologies to reduce power plant water withdrawals
and consumption and improve the quality of water related to power generation.
Operated by the Southern Research Institute, the WRC is being developed by
Southern Company and its subsidiary Georgia Power, Southern Research and the
EPRI industry collaborative.
"Duke Energy is proud to join our industry colleagues in exploring innovative
water-management technologies in this unique research center," said Mitch
Griggs, vice president of Environmental Services for Duke Energy. "The
breakthrough results we anticipate from the Water Research Center will inform
our technology decisions and enable us to continue to provide reliable,
affordable and increasingly clean electricity to our customers well into the
Cooling water is essential for most thermal, or steam-driven, electric
generation, which is the primary form of producing power in the United States
and globally. Although most of the water withdrawn for power generation is
returned to the source, the energy industry is focused on finding more
efficient ways to manage water resources.
Evaluation of the new technology – a thermosyphon cooler developed by Johnson
Controls – is the first project to become operational at the center.
According to Johnson Controls, the technology transfers heat to the
environment without evaporative water loss by using an air-cooled refrigerant
that pre-cools water before it enters the cooling tower.
The thermosyphon cooler reduces the amount of water that must be cooled by
evaporation in the cooling tower, thus reducing water consumption.
The year-long testing at the WRC will document the technology's water savings
potential and energy consumption characteristics.
The WRC is being designed to accommodate development and evaluation of power
plant water management technologies in seven areas. These include cooling
tower water chemistry and advanced cooling systems; process wastewater
treatment; zero liquid discharge options; moisture recovery from power plant
processes; solids landfill water management; carbon technology water issues;
and water use modeling and monitoring for best management practices.
The technologies being explored at the WRC can be implemented by power
companies worldwide to address water issues and also will educate students and
community leaders about the importance of water conservation and the
technologies being developed to reduce water consumption.
