  • Turning Flue Gas Carbon into a Raw Material for Manufacturing

    Bayer in February brought online a pilot plant at Chempark Leverkusen, Germany, to recycle carbon dioxide (CO2) scrubbed from the flue gas of a 1,000-MW RWE lignite-fired unit and convert it into a raw material and petroleum substitute for plastic manufacturing. The Bayer facility (Figure 4) essentially produces a chemical precursor into which CO2 is incorporated and then processed into polyurethanes that are used for many everyday items.

    This web supplement to "Changing Winds: The Evolving Wind Turbine" examines the debate over the merits of the two most common wind turbine axis orientations.

  • Plan for the Worst: Insurance Insights

    Imagine this scenario: Two separate power plants experience a bowing problem greater than 18 mils with a steam-turbine rotor. The turbines are from the same manufacturer and several repair options are reviewed. Management at both plants selects an innovative approach involving removal of a substantial amount of material, which is replaced with weld overlay and then machined to correct diameters and centerline of the balance piston area. One plant’s insurance company covers the repair, the other plant’s doesn’t. Why?

  • Electricity: A Fuel of the Future

    The recent tensions in the Middle East and their impact on oil and gasoline prices remind us that the U.S. remains heavily dependent on foreign nations—some of them unstable—to meet many of our energy needs. Of course, oil will continue to have an important place in our energy mix, and expanding our domestic reserves makes sense.

  • EPA Proposes Cooling Water Intake Rules

    Rules proposed by the Environmental Protection Agency (EPA) under Section 316(b) of the Clean Water Act on Monday call for flexible technology standards, determined on a case-by-case basis, for more than 670 power plants across the nation that pull in at least 2 million gallons per day of cooling water. The EPA said the proposal, which seeks to protect aquatic life, establishes a “common sense framework, putting a premium on public input and flexibility.”

  • FERC: Negawatts on a Par with Megawatts

    The Federal Energy Regulatory Commission (FERC) yesterday established a new rule that puts demand response (DR) on a par with power generation. The rule requires organized wholesale energy market operators to pay DR resources the market price for energy, known as the locational marginal price (LMP), when those resources have the capability to balance supply and demand as an alternative to a generation resource and when dispatch of those resources is cost-effective.

  • Xcel to Repower Black Dog Coal-Fired Units with Natural Gas

    Xcel Energy wants to retire its last two coal-fired power plants (Units 3 and 4) at the Black Dog power plant in Burnsville, Minn., and replace them with natural gas–fired units. Black Dog Units 1 and 2 were converted to natural gas combined-cycle operation in 2002. Xcel says the conversion would be “more economical” than alternatives.
