Fracking Problems
By most estimates, natural gas is likely to become the dominant power generation fuel in the U.S. within perhaps a decade. The rapid growth in natural gas supplies follows advanced drilling techniques that can economically tap large shale gas reserves located deep beneath Earth’s crust. Unfortunately, it only takes one outlaw drilling company to frack it up for the rest of us.

Systems Integration, Flexible Control Reduce Makeup Water Cost
Longview Power, a 695-MW coal-fired power plant now under construction in Maidsville, W.Va., is scheduled to begin commercial operation later this year. The $2 billion project reached 580 MW in early June, just a month after completing the “first fire on coal” schedule milestone. Testing and tuning of the controls and various systems continue.

Improving the Efficiency of Toronto’s District Heating Plant
Enwave Energy Corp.’s district heating plants in downtown Toronto will be operating cleaner and more efficiently before the fall 2011 heating season begins when boiler upgrades now under way are completed. Enwave hired Benz Air Engineering (BAE) to design and install upgrades to all eight boilers inside Enwave’s Pearl Street Station. When the $20 million project is completed, the retrofits will produce energy savings exceeding $5 million per year. In addition, the company will receive incentives of $100,000 per boiler from Enbridge, its natural gas provider.

Chile, Peru Put the Brakes on Mega-Hydro Projects
Weeks after Brazil’s environmental agency, IBAMA, granted final approval for construction of the mammoth 11.2-GW Belo Monte Dam in the Amazon region to proceed, an appeals court in Chile suspended plans for the 2.75-GW multi-dam HidroAysen project in the Patagonia region, and Peru’s government terminated a concession for the 1.5-GW Inambari in the Peruvian Amazon area after month-long mass protests (Figure 5).

Fighting Pipe Abrasion
Steel piping systems used to convey coarse materials, often over long distances, are under constant attack from abrasion. In power plants, the materials are usually coal and limestone slurry. The common industry solution has been to install abrasion resistant (AR) pipe that is much harder on the Brinnell Scale than standard steel pipe. The harder the inner wall, studies have shown, the better it resists the gouging or plowing action of abrasive sliding particle flow.

Osmotic Power Makes Headway
Statkraft began operating its 4-kW prototype osmotic power plant at Tofte, just outside Oslo, Norway, in 2009. Now the firm reports that it is close to developing a large-scale plant. In June, Statkraft and Japanese materials manufacturer Nitto Denko/Hydranautics signed an agreement for the development and supply of membranes specifically designed for use in large-scale osmotic power plants.
