  • Firstenergy to Convert Coal-Fired Burger Plant to Biomass

    Confronted with a district court ultimatum that would have forced it to install expensive pollution controls or close two coal-fired units at its R.E. Burger Plant in Shadyside, Ohio, Akron-based FirstEnergy Corp. announced in April that it would convert them to biomass. When the $200 million retrofit is complete, as is expected by 2013, the Burger Plant will likely be one of the largest biomass facilities in the U.S.

  • Powering the People: India’s Capacity Expansion Plans

    India has become a global business power even though hundreds of millions of its citizens still live in poverty. To sustain economic growth and lift its people out of poverty, India needs more — and more reliable — power. Details of government plans for achieving those goals demonstrate that pragmatism may be in shorter supply than ambition and political will.

  • Interest in Solar Tower Technology Rising

    Though solar thermal tower technology has been around since the 1970s, to date, only one plant in the world commercially generates electricity: Abengoa Solar’s 11-MW PS10 tower just outside Seville, in Spain’s Andalucía desert has been grid-connected since early 2007. Because the technology relies on heat from solar energy that is reflected by mirror arrays (heliostats) onto a tower-mounted receiver, installations tend to be site-specific, expensive, and high-maintenance.

  • The Foreign Investment Factor (supplement to Powering the People: India’s Capacity Expansion Plans)

    Recognizing that the long-term sunk cost, long project planning and construction timeframe, and high-risk portfolio make it difficult for private investors to raise funds whose maturity matches project completion dates, the Indian government has since 1991 allowed 100% foreign direct investment in the power sector.

  • Boiler-Tuning Basics, Part II

    Boilers have enormous thermal mass and are relatively slow to react. Turbines are nimble and quickly answer an operator’s command. Coordinating an entire plant requires an intimate knowledge of both systems and selecting the right logic tools to bring them together.

  • Tidal Barrages Could Power 5% of UK

    Barrages across the Solway Firth, Morecambe Bay, and the Mersey and Dee estuaries in the northwest UK could provide more than 5% of the nation’s electricity and meet half the region’s electricity, a study by engineers at the University of Liverpool has found.

  • Nuclear Uprates Add Critical Capacity

    New-generation nuclear plants may be having trouble getting out of the gate, but that doesn’t mean that nuclear capacity additions are at a standstill. In fact, the 104 operating nuclear units in the U.S. have added substantial new capacity in the form of reactor and plant uprates over the past 20 years. Power uprates alone have added more than 5,600 MW since 1998 — the equivalent of five new nuclear plants.

  • Geologists Map Carbon-Trapping Rock Formations

    U.S. scientists concerned about carbon dioxide (CO2) leaks from sequestration attempts have been pursuing the option of natural chemical reactions within the earth to turn the carbon back into a solid, and they have identified an abundant supply of large rock formations around the world that could be used a vast sink for the heat-trapping gas.

  • Birth Pangs of the Nuclear Renaissance

    The much-ballyhooed U.S. nuclear renaissance, with a few exceptions, is running late, thanks to the usual Washington bureaucratic quagmire plus the added risk resulting from crumbling financial markets. The future doesn’t look much brighter. The poor outlook for Yucca Mountain and the new administration’s general indifference to nuclear power have made a rebirth of the nuclear industry an even higher-risk proposition than before.

  • Tapping Geothermal Energy with a Comprehensive Strategy

    Geothermal energy in Europe may have been used for centuries — it was popularized by the Romans and adopted by the Turks — but geothermal-generated electricity was first produced at Larderello, Italy, in 1904. Since then, its growth on the continent has shot up to 820 MW. But, according to the European Renewable Energy Council, the resource’s full potential has barely been harnessed.
