The latest benchmarking study by the EUCG examines the technology and costs of 49 flue gas desulfurization systems currently under design or construction by 12 of the nation’s largest utilities. Although the study’s detailed results are proprietary to EUCG members that participated in it, POWER was given access to the top-level findings. To get details at the plant/unit level, you’ll have to join the EUCG and participate in the study, which is ongoing.

The U.S. Department of Energy (DOE) and Great River Energy are testing a new coal-drying technology that could dramatically reduce the emissions of lignite-burning power plants. The project was selected for funding during Round I of the DOE’s Clean Coal Power Initiative (CCPI), a series of competitions to demonstrate a range of promising clean-coal technologies. […]

Are you using your flue gas desulfurization (FGD) system to its highest potential? You might not be if you’re not making it do double duty. It seems that million-dollar wet scrubber you installed to rid your flue gases of sulfur dioxide also can do a decent job of capturing mercury — under the right conditions. […]

If little else is clear about the future of the U.S. power industry, this much is: Electricity rates are going up across the country, and will continue to. None of the esteemed panelists at the CEO session of the ELECTRIC POWER 2007 Conference & Exhibition in Chicago last month actually said those words. But much […]

In a carbon-constrained world, CO2 capture and storage (CCS), although considered the most radical of the carbon abatement technologies (CATs), seems to be favored over combustion and steam cycle improvements alone. However, CCS is the least commercially developed of the CAT options; at present, there are only field prototypes for its various forms. Nonetheless, most […]

  State policy makers are characteristically reluctant to recognize that they have advanced a policy as far as they can, and that they must cede some control to fully realize its ultimate benefits. Ceding control often runs counter to policy makers’ political instinct to serve their constituents. Doing so is even harder when a new […]

Sylvester Stallone, as Rocky Balboa, staged another magical comeback earlier this year — in the ring and at the box office. Just when you think Rocky is down and out for good, the sixth release of the Rocky franchise just may be the best of the lot. "Down but not out" is also an apt […]

Reducing NOx emissions from large utility coal-fired boilers has been a primary focus of the U.S. power generation industry since passage of the 1970 Clean Air Act and subsequent legislation. By the early 1990s, nearly all such boilers had installed some form of low-NOx burner (LNB) technology and/or overfire air (OFA) — the least expensive […]
