Kevin Luke of Buford-based Z-4 Energy Systems wants to develop a way to save wind energy for when the wind's not blowing. He's working on a commercialization plan for wind-powered water pumping, incorporating compressed air storage. Luke points out that wind is variable and energy storage is needed to provide controlled, consistent water pumping. He seeks to use air compressors, similar to those found commercially, powered by a wind turbine rotor. The driving force behind his efforts is that the wind blows at variable speeds and when there is not enough wind to turn the turbine, the stored air can continue to be used to pump the well. Currently, wind electric and solar powered systems use lead acid batteries for storage, which don't perform well in the cold weather and have a short lifespan.

Greenblatt noted that while wind power could produce impressive amounts of peak energy during strong gusts, the biggest problem was wind power’s intermittency. The problem could be addressed by a process called compressed air energy storage, where excess energy could be used to pump compressed air into underground storage facilities that could include abandoned mines. When the wind was not blowing, he said, the compressed air could be tapped and combined with the burning of natural gas to create high-efficiency electrical generators approximating the efficiency levels of coal-fueled power plants.

But Manchin's proposal went a step beyond talk and ideas, setting out a concrete way to begin attracting more money to development of ethanol, biodiesel, solar, wind or biomass electricity generation. “I've always been told the $35, $40 range (per barrel of oil) is where alternative fuels become viable” Manchin told The News-Record after a tour of Arch Coal's Black Thunder mine. “Let's find that benchmark ... I don't see another way.”

WASHINGTON -- Federal officials vowed this week to boost renewable energy production on federal lands in the West, but wind and geothermal industry officials criticized the administration for a lack of openness and support leading to delays in some of their projects.

Energy corridors should enhance markets for both fossil-based energy as well as wind and other renewables, as the federal government prepares for a wave of electrical transmission and pipeline construction across the West.
